+"""Mint a provider API key by running a command (``key_cmd``).
+
+Static API keys are the exception at enterprise gateways: SSO/OIDC brokers,
+cloud IAM, and internal auth proxies all issue SHORT-LIVED bearers instead.
+A key copied into ``.env`` (``key_env``) is stale within the hour, so every
+request after that 401s and the user has to restart the session.
+
+``key_cmd`` names a command that PRINTS a token, so the credential is derived
+rather than stored::
+
+    providers:
+      my-gateway:
+        base_url: https://gateway.internal.example.com/v1
+        api_mode: chat_completions
+        key_cmd: my-auth-cli print-token --profile prod
+
+This is the established pattern for agent tooling — Claude Code's
+``apiKeyHelper``, the ``gcloud auth print-access-token`` / ``aws ecr
+get-login-password`` idiom, and vendor helpers such as ``databricks auth
+token`` all expose exactly this contract. Hermes already accepts a callable
+API key on both wire clients (the Entra ID / Azure identity path) and invokes
+it per request, so nothing downstream changes: the token is simply always
+fresh. It is cached until shortly before expiry, so the command runs about
+once per token lifetime rather than once per request.
+
+Output contract: print ONLY the token on stdout, either bare or as JSON with
+an ``access_token`` field (``expires_in`` is honoured when present) — the
+shape OAuth 2.0 token endpoints and the helpers above already emit.
+
+Precedence: an explicit ``--api-key`` still wins (the one-off recovery escape
+hatch); otherwise ``key_cmd`` is preferred over a static ``api_key`` /
+``key_env`` on the same entry.

+"""Unified deadline layer — one bounded-execution primitive, one timeout resolver.
+
+Phase 1 of the architectural fix for the timeout/hang backlog
+(https://github.com/NousResearch/hermes-agent/issues/85125).
+
+The tree currently carries at least six site-local deadline mechanisms, each
+built for one incident, none shared (tool_executor batch deadline, telegram
+``_await_with_thread_deadline``, gateway turn lease, reasoning stale floors,
+``human_wait_ceiling``, per-MCP-handler timeouts).  Every new stall report
+grows that list by one.  This module is the shared foundation the call sites
+migrate onto in later phases:
+
+* :func:`resolve_timeout` — one config-first resolution path for timeout
+  values (``timeouts:`` section in config.yaml > legacy env var > default),
+  so new surfaces stop inventing ``HERMES_*_TIMEOUT`` env vars (".env is for
+  secrets only") and hardcoded literals stop ignoring user config
+  (#63302, #53161, #43272 class).
+
+* :func:`clamp_timeout` — platform-safe clamping.  Large user-supplied
+  timeouts overflow ``time_t`` inside ``threading.Lock.acquire(timeout=...)``
+  / ``Thread.join(timeout=...)`` on macOS and kill whole tool batches
+  (#83220).  Clamping at the shared boundary fixes that class once, for
+  every consumer.
+
+* :func:`run_bounded_async` — a wall-clock deadline for awaitables that does
+  NOT depend on event-loop timers.  ``asyncio.wait_for`` schedules its expiry
+  on the loop; when the loop thread itself is blocked in a synchronous call
+  (family A of the #84047 stall triage), every asyncio-based timeout in the
+  process is silently disabled.  This helper drives the deadline from a
+  daemon ``threading.Timer`` (generalizing the proven telegram-adapter
+  primitive) and abandons cancellation-shielded tasks instead of waiting for
+  cancellation to complete.  The telegram adapter's private copy
+  (``plugins/platforms/telegram/adapter.py:_await_with_thread_deadline``)
+  migrates onto this in Phase 2 of #85125 — do not let the two drift in the
+  meantime; fix bugs here first.
+
+* :func:`run_bounded_sync` — the same contract for synchronous callables
+  bounded from a synchronous context (daemon worker thread, abandoned on
+  expiry).
+
+* :func:`kill_process_tree` — portable whole-tree termination so
+  kill-on-timeout stops orphaning descendants (#71148, #59549, #84967,
+  #68139 class).  Existing site-local tree-kills that migrate onto this in
+  Phase 4 of #85125: ``gateway/status.py`` (taskkill wrapper + psutil
+  snapshot/reap pair) and ``tools/code_execution_tool.py`` (psutil
+  recursive children kill).
+
+Design invariants:
+
+* Exceptions raised by the bounded operation propagate unchanged — callers
+  keep their existing error handling.  Only the *timeout* outcome is
+  reified (as :class:`BoundedResult`), because that is the outcome the
+  call sites keep getting wrong.
+* A timeout produced by this layer is OUR deadline, not the provider's.
+  Callers that feed errors into ``agent/error_classifier.py`` should

+"""Deterministic-empty detection and cost-aware retry budgets (NS-503).
+
+When a provider returns an empty completion, the agent loop retries up to
+3 times and then walks the fallback chain. Every attempt re-sends the full
+conversation input — at large context on paid routes this bills the user
+repeatedly for a turn that produces no text (the "charged ~$2.33 for an
+empty answer" incident class).
+
+Signaled refusals (``finish_reason="content_filter"``, Anthropic
+``stop_reason="refusal"``, Bedrock guardrails) are already terminal and
+never reach the empty-retry loop. This module addresses the *unsignaled*
+empties: the provider reports a successful completion with zero output
+tokens and a generic finish reason (portal-proxied refusals commonly look
+like this).
+
+Two independent guards, both failing OPEN to today's behaviour:
+
+1. **Deterministic-empty detection** — two consecutive empty attempts,
+   both with usage present and ``output_tokens == 0``, from the same
+   (model, provider, finish_reason), are treated as deterministic: the
+   same prompt will keep producing the same empty. Remaining retries are
+   skipped and the loop proceeds straight to the fallback chain (a
+   different model may behave differently). Attempts with missing usage
+   or ``output_tokens > 0`` (model generated *something* — think-block
+   stripping, whitespace, flaky decoding) never classify as deterministic
+   and keep the full retry budget.
+
+2. **Cost-aware retry budget** — when the estimated input cost of a
+   single empty attempt exceeds the configured threshold (default
+   $0.25), the empty-retry budget for this streak drops from 3 to 1.
+   Unknown pricing, missing usage, or included/subscription routes
+   leave the budget untouched.
+
+Configured via the additive ``agent.empty_response_guard`` section in
+``config.yaml`` (resolved once at agent init by ``agent_init``)::
+
+    agent:
+      empty_response_guard:
+        enabled: true            # false = legacy fixed 3-retry behaviour
+        cost_threshold_usd: 0.25 # per-attempt cost that halves the budget
+
+Per project policy, no ``HERMES_*`` environment variables are involved —
+``.env`` is reserved for credentials; behavioural settings live in
+``config.yaml``.

+"""Rotation-stable logical cache scope for prompt_cache_key derivation.
+
+Context-compression rotation (legacy ``compression.in_place: false`` mode)
+mints a new physical ``session_id`` mid-conversation to segment the
+transcript. The prompt-cache scope introduced by #79161 was derived from that
+physical id, so every rotation moved the conversation into a fresh cache
+bucket even though it is logically the same conversation continuing
+(issue #79017).
+
+``resolve_prompt_cache_scope()`` maps the physical session id to the ROOT of
+its *compression lineage* — the pre-rotation session id — using
+``SessionDB.get_compression_lineage()``, whose fork-aware semantics
+(hardened in #79193) give exactly the scope boundaries the cache key needs.
+NOT ``SessionDB.get_conversation_root`` / ``run_agent._conversation_root_id``
+(the Portal-attribution walk): that one follows ``parent_session_id`` blindly,
+collapsing /branch children and whole delegate trees into one id, which would
+violate the #79161 isolation this scope must preserve. The two resolvers are
+intentionally different — do not "deduplicate" them.
+
+- compression-rotation children walk back to the original segment
+  (rotation-stable scope — the fix);
+- ``/new`` starts a lineage-less session (fresh scope);
+- ``/branch`` children (``_branched_from``), delegate subagents
+  (``_delegate_from``), and tool-tagged children (``source="tool"``) are
+  explicit fork children and keep their own isolated scope, preserving the
+  sibling/subagent isolation #79161 established;
+- cron fires keep their physical ``cron_<job>_<ts>`` id here — the per-fire
+  timestamp is stripped later by ``_cache_scope_from_session_id`` exactly as
+  before.
+
+The resolution is memoized per (agent, session_id): the lineage walk runs
+once per transcript segment — NOT per API call — and re-runs only when
+rotation actually changes ``agent.session_id`` (per the no-DB-on-the-hot-path
+constraint recorded on #79017). Default installs compact in place and never
+rotate, so they hit the memo forever and behave byte-identically to before.

+"""Cheap content-sanity checks for the truncated-response continuation path.
+
+Issue #86581: a model in a degenerate repetition loop can spend its ENTIRE
+output budget echoing one fragment.  The ``finish_reason=length``
+continuation path in ``conversation_loop.py`` would then retry with a
+"continue, don't repeat" nudge — stitching a pathological fragment into the
+final response with no content-sanity check.  In the incident behind #86581
+a single turn produced a 60,698-char response delivered as 31 Discord
+messages.
+
+These helpers detect repetition-dominated fragments BEFORE the continuation
+nudge is appended so the turn can abort with a clear user-facing error
+(mirroring the existing ``_thinking_exhausted`` guard) instead of flooding.
+
+The detection is deliberately conservative: only LONG verbatim repeats
+(60+ chars) whose occurrences cover a majority of the fragment trip the
+guard, so ordinary truncated responses (a sentence cut mid-word, a heading
+repeated, code with similar-looking lines) are never blocked.

+    are replayed alongside an encrypted ``reasoning`` item (HTTP 400

+/**
+ * Renderer-bundle skew detection.
+ *
+ * The desktop UI (including bundled plugins like Bot Mode) is compiled into
+ * the app binary at build time, while `hermes update` only moves the source
+ * tree. A user who updates from the terminal — or whose in-app update failed
+ * on the bundle-swap leg — ends up running a NEW runtime under an OLD
+ * renderer: About proudly reports the new Hermes version while the sidebar
+ * is missing the features that version shipped (the "no Bots tab after the
+ * Bot Mode update" reports).
+ *
+ * Detection: the packaged build carries install-stamp.json with the commit
+ * it was built from. If commits touching `apps/desktop/` exist in the source
+ * tree AFTER that stamp commit, the running renderer is provably missing
+ * desktop changes the installed runtime has:
+ *
+ *   git rev-list --count <stampCommit>..HEAD -- apps/desktop
+ *
+ * Scoping to `apps/desktop/` keeps this quiet for the common case where the
+ * repo advances with agent-only changes — a shell built before those is not
+ * stale in any way the user can see.
+ *
+ * Fail-quiet by design: no stamp (dev runs), a fallback all-zero stamp
+ * (non-git build), an unknown commit (stamp predates a shallow clone's
+ * history), or any git failure all report "not stale". This warning must
+ * never false-positive — it tells users their install is torn.
+ *

+/**
+ * connection-registry.ts
+ *
+ * Pure, electron-free helpers for the desktop's multi-connection registry —
+ * the v2 successor to the single global `mode` + `remote` block in
+ * connection.json. The registry is a named list of agent SOURCES (local
+ * runtime, remote gateways, Hermes Cloud instances, SSH hosts) that are all
+ * registered at once; routing/pooling changes that consume the registry land
+ * separately, so this module is deliberately storage-shaped, not
+ * transport-shaped.
+ *
+ * Design rules (agreed with Teknium, Aug 2026):
+ *  - Every connection carries a REQUIRED, registry-unique `label` (the
+ *    "device name"). Uniqueness is case-insensitive so `Homelab` and
+ *    `homelab` can't coexist and produce two identical badges.
+ *  - When two sources expose the same profile name, surfaces disambiguate as
+ *    `@<profile>-<label-slug>` — `agentHandle()` is the one place that rule
+ *    lives.
+ *  - The registry ALWAYS contains exactly one `local` connection (the app's
+ *    own runtime). It cannot be removed; it is the default primary.
+ *  - `primary` designates the connection that owns the window backend (boot
+ *    overlay, install/update machinery). Removing the primary retargets to
+ *    the local entry rather than leaving a dangling id.
+ *
+ * Kept standalone (no `import 'electron'`) so it unit-tests with `node --test`
+ * — same pattern as connection-config.ts / backend-probes.ts. main.ts wires
+ * these into the IPC layer and owns file I/O + secret encryption.

+// Launching the Hermes TUI in the user's OWN terminal emulator.
+//
+// This is deliberately NOT the in-app terminal pane: the point of the verb is
+// to hand a session to the terminal the user already lives in, running
+// `hermes --tui --resume <id>` there. Two problems have to be solved for that
+// to work anywhere:
+//
+//  1. WHAT to run. The desktop's Hermes runtime is often a venv Python invoked
+//     as `python -m hermes_cli.main`, not a `hermes` on PATH — so the command
+//     and its PYTHONPATH have to be carried over verbatim. We write them into a
+//     small launcher script instead of trying to quote a nested command through
+//     a terminal emulator's `-e` argument, which every emulator parses
+//     differently.
+//  2. WHERE to run it. There is no portable "default terminal" API, so each
+//     platform gets its own resolution:
+//       - macOS: `open` the `.command` script with NO `-a`, letting
+//         LaunchServices route it to whichever app the user has bound to shell
+//         scripts (Terminal.app by default, iTerm2/Ghostty/WezTerm when they've
+//         claimed it). That is the closest thing macOS has to "their terminal".
+//       - Linux: an ordered ladder of emulators, led by Debian's
+//         `x-terminal-emulator` alternative — which IS the user's configured
+//         choice — before falling back to the common concrete emulators.
+//       - Windows: Windows Terminal when installed, else a `cmd.exe` console.
+//
+// Everything here is pure so it can be unit-tested without Electron; the side
+// effects (writing the script, spawning) live in main.ts.

+ *    backend), but the stop promise keeps the process handle until the
+ *    bounded SIGTERM -> SIGKILL escalation in waitForExit resolves;
+ *  - concurrent stop requests for one key share the single in-flight stop;
+ *  - spawn paths can await inFlight(key) so a fresh child never overlaps a
+ *    dying one on the same HERMES_HOME.
+ *
+ * Extracted into a dependency-free module (same pattern as backend-child.ts /

+// MCP server spawns, and the Electron-side binary resolvers.
+//
+// Fix (same approach as VS Code's shell-environment resolution; ported from

+// capture $PATH between sentinel markers so profile banners can't corrupt the

+/**
+ * `::preview{file="…"}` — a workspace HTML file rendered LIVE inside the
+ * assistant message. A sandboxed iframe with an opaque origin
+ * (`sandbox="allow-scripts"`, deliberately no `allow-same-origin`): scripts
+ * run and the widget is fully interactive, but the document cannot reach the
+ * app, its cookies, storage, or the bridge. The doc arrives via `srcdoc`
+ * from a bridge file read, so single-file HTML (what agents generate) is
+ * fully live; relative sibling assets don't resolve in an opaque origin.
+ *
+ * SIZE IS CONTENT-DRIVEN. The opaque origin means the parent can't measure
+ * the document, but we own the srcdoc string — an injected script posts the
+ * content's size up via postMessage (tagged with a per-mount token). Height
+ * tracks live within the clamp band; width adopts ONCE from the first
+ * report, so a fixed-size widget shrink-wraps and sits left in the message
+ * flow like an image, while a fluid page measures the full viewport and
+ * stays column-wide. A `height="480"` attribute only sets the starting
+ * height — measurement always wins.
+ *
+ * NATIVE BY DEFAULT. A theme prelude injects first: the app's resolved
+ * theme tokens under friendly names (--foreground, --muted-foreground,
+ * --accent, --border, --card), the app font, zero body margin/padding, and
+ * a transparent background — so widget-shaped content reads as part of the
+ * app. The page's own styles override all of it, so a full page keeps its
+ * own design.
+ *
+ * WIDGETS TALK BACK OFF-SCREEN. `window.hermes.send(prompt)` (or declarative
+ * `data-hermes-send` on any clickable element) routes the prompt through the
+ * composer's send path as a user turn typed `display_kind=hidden`: the agent
+ * wakes and the durable row exists (context, resume, audit via the DB), but
+ * no bubble renders — the widget updating is the visible response. Token-
+ * gated, length-capped, throttled to human speed.
+ *
+ * Non-HTML targets and remote gateways (no local file access) fall back to
+ * the standard preview-attachment card rather than a broken frame.

+/**
+ * Budgeted renderer loop — the one way to run a decorative rAF animation.
+ *
+ * Desktop has repeatedly shipped the same bug class: an animation loop that
+ * never sleeps (bots face clock #88543, pixel egg #88406, diffusion
+ * placeholder #88564, status pulse / spinner in the #77651 wave). Each fix
+ * re-implemented the same four behaviors by hand. This helper owns them:
+ *
+ *  - **fps budget** — paints are skipped until `1000 / fps` elapsed; the loop
+ *    still rides rAF so Chromium can align and pause it natively.
+ *  - **observability pause** — wired to `createRendererLoopPauseController`:
+ *    the loop cancels while the window is hidden, minimized, or unfocused and
+ *    resumes when observable.
+ *  - **idle dormancy** — when `idleWhen()` returns true after a draw, the loop
+ *    parks (zero pending frames, zero timers) until `wake()` is called. This
+ *    is the piece every hand-rolled loop forgot: "nothing visible to animate"
+ *    must cost nothing.
+ *  - **teardown** — `dispose()` cancels the frame, disposes the pause
+ *    controller, and makes every later `wake()` a no-op. Callers MUST call it
+ *    from their effect cleanup / plugin disposer.
+ *
+ * Usage:
+ *
+ * ```ts
+ * const loop = createBudgetedLoop(now => paint(now), {
+ *   fps: 15,
+ *   idleWhen: () => visibleThings.size === 0
+ * })
+ * // something became animatable again:
+ * loop.wake()
+ * // effect cleanup / plugin disable:
+ * loop.dispose()
+ * ```

+ * simultaneously (see apps/desktop/AGENTS.md and the keep-alive comment in
+ * apps/desktop/src/app/chat/index.tsx), so a global search matches across

+ * they press ⌘F in a chat — they expect to search the chat they are reading
+ * (#81726).
+ *
+ * Strategy. At bar-open time, capture the active chat surface element and
+ * remember it for the lifetime of the find bar. Subsequent queries highlight
+ * only text nodes inside that subtree. ⌘G / ⌘⇧G step between highlights
+ * inside the same subtree. Closing the bar unwraps the highlights. If a

+ * (the route didn't change, so the FindBar's pathname cleanup never ran),
+ * the scope re-resolves to the new foreground surface — "find wherever the
+ * user is reading" holds across a flip, not just at open time (#81726).
+ *
+ * "Current view" is the foreground `[data-chat-surface]` element after
+ * filtering out inactive keep-alive tabs. That is the same policy every
+ * other document-wide lookup obeys (see pane-visibility.ts), so this can be
+ * reasoned about as "find wherever the user is reading".
+ *
+ * Implementation notes:
+ * - We wrap each match in a `<mark class="find-hit">` so the active match is
+ *   a single class toggle. Walking raw text nodes lets us split a node that
+ *   spans a match boundary without disturbing the surrounding React tree
+ *   (text nodes are inert for React reconciliation until the parent changes).
+ * - The active ordinal is the 1-indexed position of the match whose
+ *   `<mark>` carries `data-active`. We re-derive it on every step instead of
+ *   keeping a counter, so a stale count after a DOM mutation self-heals on
+ *   the next search.
+ * - The transcript is React-owned and re-renders while the bar is open —
+ *   assistant responses stream through `markdown-text.tsx`, which rebuilds
+ *   the markdown DOM on every delta, and a new message is appended whenever
+ *   the assistant answers. React does not know about the `<mark>`s we insert,
+ *   so a re-render of a region whose text or structure changed detaches our
+ *   marks (React re-allocates those nodes) while leaving marks in untouched
+ *   regions intact. To keep highlights consistent across those renders we
+ *   watch the captured scope with a MutationObserver and re-apply the wrap
+ *   whenever an unmarked occurrence of the query reappears — but ONLY then,
+ *   so a responsive render that left every mark in place costs nothing and an
+ *   append that adds no matching text is a no-op. The observer is gated off
+ *   while WE are mutating (a re-entrancy flag), coalesced to one re-apply per
+ *   microtask, and torn down when the bar closes (#81726).
+ * - We do NOT call `webContents.findInPage` from here. That bridge still
+ *   exists for multi-window secondary sessions (each window searches its
+ *   own webContents), but for the primary window it cannot be scoped, so
+ *   the renderer-side walker is the only path that satisfies the issue.

+ * remote entry declares its own `suggest.keywords` / `suggest.hosts`, served
+ * through `GET /api/mcp/catalog`. The suggestion provider and the inline
+ * setup card read the catalog first.
  *
- *   1. keyword → suggestion pills over the composer ("you typed jira…"),
- *   2. giving the inline setup card a config to write via the ordinary
- *      `POST /api/mcp/servers` endpoint — the exact same path as pasting the
- *      vendor's snippet into the Capabilities editor by hand.
+ * This static list remains ONLY for older backends whose catalog responses
+ * carry no `suggest` field (the provider falls back to it when the catalog
+ * yields zero suggestible entries). Do not add new vendors here — add a
+ * manifest under `optional-mcps/` instead. Remove this file at the next
+ * backend contract bump.
  *
- * Nothing here changes base Hermes behavior: no backend code reads this file,
- * entries are URL-only remotes (no local process is ever spawned from a
- * suggestion), and every install still lands in config.yaml through the
- * existing validated endpoint. If an entry ALSO exists in the install catalog
- * (e.g. linear, figma), the setup card prefers the catalog path.
+ * GitHub is intentionally absent (here AND in the catalog): its hosted MCP
+ * requires each MCP host to provide its own OAuth app (generic Dynamic
+ * Client Registration 404s at /register), and the bundled github/* skills
+ * via the gh CLI are the more capable integration. The composer's github
+ * suggestion provider offers the `github-auth` skill instead.

+/**
+ * Hermes Bot Mode — a "one chat per agent" roster for the Hermes desktop.
+ *
+ * Left pane "Bots": one row per Hermes profile (a bot = an agent profile) with
+ * a customizable avatar (shape + color + eyes, image, or pet). Click opens that
+ * bot's chat; right-click → Edit Profile (avatar, title, description).
+ * "New Agent" creates a profile — Name / Title / Description with an
+ * "Advanced" disclosure for full profile config.
+ *
+ * Right tile "Routines": scheduled tasks (Hermes cron jobs) scoped to the
+ * bot you're currently chatting with — follows the live gateway profile.
+ *
+ * Bots message each other straight into each bot's ONE canonical "Bot
+ * Chat" — @-mentions deliver over gateway RPCs (no CLI relay), and
+ * bot-initiated sends use `hermes -p <bot> chat --in ~ -c "Bot Chat"`.

+/**
+ * Native kanban terminal-event notification (completion, blocker, failure).
+ *
+ * No maintained exact-fit OSS exists and the SDK
+ * has no kanban event door, so this module rides the kanban plugin's EXISTING
+ * /events socket (api.ts onEventsFrame). No new WebSocket, no new process,
+ * no DB, no auth, no persistence — cursor is an in-memory per-board high-water
+ * mark. Notifies on the same terminal kinds the gateway watcher pings
+ * (gateway/kanban_watchers.py): 'completed' (kanban_db.complete_task —
+ * payload: summary + artifacts), 'blocked' (payload: reason), 'gave_up'
+ * (payload: error), 'crashed', 'timed_out', and 'block_loop_detected'
+ * (payload: reason — the routed-to-triage human handoff).
+ *
+ * Two delivery doors, complementary by design:
+ *  - `host.notify` — the in-app toast, covers the foreground case;
+ *  - `ctx.os.notify` (when bound) — the native OS notification, which the
+ *    desktop shell fires only while the user is AWAY from Hermes. This is the
+ *    door that covers "walked away and the worker hit a blocker".
+ *
+ * Cursor contract: first observation of a board baselines
+ * seen[board] = GET /board latest_event_id (MAX task_events.id for that
+ * board). Events id <= seen are historical/replay — never notified, no
+ * cursor change. id > seen advances cursor for EVERY kind; only terminal
+ * kinds emit. Reconnect replays from 0; cursor filters. Board switch never
+ * mixes cursors; returning reuses prior cursor (never reset to current MAX).
+ * Fail-closed: while a board's baseline is unknown, no event can be
+ * classified so none is notified. Empty slug ('') suppressed.

+//  1. Removing a connection must dispose its secondaries — remote/cloud
+//     sources have no local process whose death would drop the socket, so
+//     without an explicit dispose the WebSocket stays open and streams ghost
+//     events until page reload.
+//  2. A materially edited connection re-dials so fresh sockets target the

+//  3. When the Electron main reports the connection no longer exists
+//     (`No connection with id`), the reconnect loop fail-stops and evicts
+//     the entry instead of retrying forever.

+/**
+ * PERSISTED UNREAD ("finished — unread" green dot) — the durable layer under
+ * the transient `$unreadFinishedSessionIds` atom, ported from the webui's
+ * proven design (sessions.js: viewed-count watermarks + completion markers).
+ *
+ * Two persisted records, both bucketed BY PROFILE and then keyed by the
+ * DURABLE lineage id (sessionPinId) so state survives auto-compression's
+ * session-id rotation — same durable-id rule as `$sessionColorOverrides`:
+ *
+ *  1. SEEN WATERMARKS — the message_count last acknowledged for a session
+ *     (set when the user opens it, kept current while it stays selected, and
+ *     seeded on FIRST SIGHT of an unknown session so a fresh install doesn't
+ *     paint every row green). A row whose live `message_count` exceeds its
+ *     watermark is unread — this is what reconstructs the green dot for a
+ *     session that finished while the app was CLOSED, which the live
+ *     busy→idle edge in session-states.ts can never replay after a restart.
+ *
+ *  2. EXPLICIT MARKERS — the live busy→idle edge, persisted. Covers the gap
+ *     where a turn finishes in the background but the sidebar list hasn't
+ *     refreshed its message_count yet (and any completion that adds no
+ *     stored messages), so a restart right after a finish keeps the dot.
+ *
+ * PROFILE SCOPING is not optional: session ids are caller-supplied and each
+ * remote-profile backend is its own namespace, so two profiles can hold the
+ * same id — and the lists routinely mix profiles (cron/messaging are ALWAYS
+ * cross-profile, `$sessions` is too in all-profiles mode). Unscoped keys let
+ * one profile's watermark/marker paint (or silence) another's row. The bucket
+ * is always the ROW's own `profile` (normalizeProfileKey, absent → "default"),
+ * never the live gateway's — except for the live busy→idle edge with no loaded
+ * row, which only ever fires for the ACTIVE gateway's runtimes and therefore
+ * falls back to `$activeGatewayProfile`.
+ *
+ * Both records are BOUNDED: markers cap per profile (oldest evicted),
+ * watermarks cap in total (unlisted, unmarked entries dropped first), and
+ * deleting/archiving a session drops its entries outright via
+ * {@link forgetSessionUnread}.
+ *
+ * Scope of watermark-based unread: chat + cron rows. Messaging rows get their
+ * message_count bumped by inbound human messages, so count-over-watermark
+ * would paint "finished — unread" on every new inbound text; they keep only
+ * the explicit live-edge markers (now persisted across restarts too).

+
+     - Apple HIG, Materials: "Materials help visually separate foreground
+       elements, such as text and controls, from background elements." Controls
+       sit ON a material, never directly on content; even `clear` Liquid Glass
+       is specced with a 35%-opacity dimming layer behind it over bright
+       content.
+       https://developer.apple.com/design/human-interface-guidelines/materials
+     - Firefox picture-in-picture, the closest analogue we have (a small
+       always-on-top window over arbitrary content): the close/unpip buttons
+       are `background-color: rgba(255,255,255,.8)` with a `#000` glyph — an

+   desktop is composited by WindowServer after Chromium has finished drawing
+   the frame (the same reason backdrop-filter can't frost the HUD). A glyph
+   halo has the same flaw from the other side: it guesses one backdrop
+   luminance and is grime over everything else.
+
+   So: the composer bar's exact tokens — same fill, same hairline, same bottom
+   shadow. The bar is the HUD's solved case for "our surface, over an unknown
+   desktop, in either appearance", and theme plus OS light/dark (mode 'system')
+   come free with it, because --dt-card and --ui-text-primary are the pair the
+   whole app is built on. The chip inverts with the appearance instead of

-                Ctrl+Enter as LF (c-j), distinct from plain Enter (c-m). This
-                binding makes Ctrl+Enter the equivalent of Alt+Enter on those
-                terminals, giving an Enter-involving newline keystroke
-                without requiring terminal settings changes. Ctrl+J (the raw
-                LF keystroke) also triggers this by virtue of being the same
-                key code — a harmless side effect since Ctrl+J has no
-                conflicting Hermes binding. See issue #22379.
+                This is enabled by default to match Claude Code / Codex /
+                OpenCode behavior. On Windows Terminal and similar environments,
+                Ctrl+Enter is delivered as the same c-j key code, so this also
+                covers Ctrl+Enter there. Set display.cli_multiline_shortcuts:
+                false to restore legacy c-j submit behavior on unusual POSIX

+# Browser Use Mode Benchmark
+
+The A/B battery behind PR [#81958](https://github.com/NousResearch/hermes-agent/pull/81958)
+(Browser Use CLI 3.0 mode, salvage of #66476 by @laithrw): built-in
+`browser_*` toolset vs the single `browser_exec` driver, measured as total
+task tokens / tool calls / wall clock at accuracy parity on live multi-step
+web tasks.
+
+## Design
+
+- **Arms differ only by tree + config.** `base` runs the built-in twelve
+  `browser_*` tools from a merge-base checkout; `pr` runs `browser_exec`
+  (`browser.backend: browser-use`) from the branch checkout; `prns` is `pr`
+  with the schema's helpers digest stripped to the header (isolates the
+  digest's value). Each cell gets a throwaway `HERMES_HOME`; web-fetch
+  credentials are stripped so every arm must actually drive the browser.
+- **Tasks are oracle-checked.** toscrape-family sites (stable content, no
+  anti-bot), regex oracles over the final answer. `tasks/easy.json` (5 tasks:
+  price lookup, category extract, count/aggregate, login, pagination) and
+  `tasks/hard.json` (6 tasks: full-category multi-page crawls, five-star
+  rating aggregation, JS/delayed render, login chain, cross-category
+  compare).
+- **Resume-safe.** Completed cells in `results/*.jsonl` are skipped on rerun
+  (same pattern as `scripts/toolperf_abeval`).
+- **Backend matrix.** `orchestrate.py` drives a local headless-Chrome CDP;
+  `orchestrate_cloud.py --backend nous-cloud|browserbase` provisions a real
+  cloud browser per cell through the same provider plumbing the product uses.
+
+## Run
+
+```bash
+# arms are pinned checkouts — e.g. merge-base worktree vs your branch
+export BUBENCH_BASE_TREE=/path/to/merge-base-tree
+export BUBENCH_PR_TREE=/path/to/branch-tree
+```
+
+Note: since #81958 merged (and #85170 made Browser Use the default driver),
+a current-main checkout resolves to `browser_exec` in BOTH arms. The `base`
+arm only measures the built-in `browser_*` toolset when `BUBENCH_BASE_TREE`
+is pinned to a pre-#81958 tree (the original run used the PR's merge-base
+worktree). For future A/Bs of new browser changes, pin `base` to the
+merge-base of the change under test — the arms are generic.
+

+
+sonnet-5: −30% tokens at parity. qwen3-30b: a wash — weak coders burn the
+savings retrying exec code. The token win concentrates on multi-step tasks
+and grows with task hardness; strong models also finish in fewer tool calls.
+
+Compatibility probes from the same run: Firecrawl cloud browsers attach fine
+(CDP websocket); Camofox has no CDP surface — structurally incompatible,
+hence the automatic fallback to the built-in toolset in #81958.
+
+Caveats: toscrape-family sites (no anti-bot, no heavy SPA); n<=3 per cell;
+success-rate deltas at this n are noise — audit sub-100% cells run-by-run
+before calling a regression.
+
+## Provenance
+
+The original per-run `results*.jsonl` files lived in `/tmp/bu-bench/` (tmpfs)
+and were lost in a host reboot on Aug 12 2026. The harness, task definitions,
+and aggregate readouts in this directory were recovered verbatim from the
+session transcripts of the benchmark run (session `20260808_050008_5f615e`
+tool-call history); `single_run.py`/`orchestrate*.py` are the recovered
+scripts with the hardcoded `/tmp/bu-bench` paths parameterized. Rerunning the
+battery reproduces fresh per-run data.

+# Compaction Eval Harness
+
+Measures what context compaction actually costs in *recall*, not just tokens.
+
+## What it does
+
+1. Takes a real long transcript (JSON: `{"messages": [...]}`, chat format).
+2. Generates a bank of factual recall questions from the region that
+   compaction will summarize away (cached per transcript for reproducibility).
+3. Runs the transcript through `ContextCompressor.compress()` under each
+   policy in the matrix (current default, aggressive tail, codex-style, ...).
+4. For each policy, asks a fresh LLM the recall questions with ONLY the
+   post-compaction context, and judges answers against gold.
+5. Emits a scorecard: recall accuracy vs tokens retained, per policy.
+
+## Usage
+
+```bash
+# from repo root, venv active
+python evals/compaction/runner.py \
+    --transcript /path/to/lineage.json \
+    --policies current,aggressive,floor10k \
+    --questions 15 \
+    --out evals/compaction/results/run1
+python evals/compaction/report.py evals/compaction/results/run1
+```
+
+Transcripts are NOT committed (they contain real session data). Point
+`--transcript` at a local file. See `fixtures.py` for the expected shape and
+a synthetic-transcript generator used by CI smoke tests.
+
+## Building transcripts from real sessions (`scripts/`)
+
+Compaction rotations mean a single active session rarely exceeds ~300K
+tokens, but the *lineage* (parent→children chain) carries the full
+uncompacted history. The scripts reconstruct those into eval transcripts:
+
+```bash
+# 1. ALWAYS copy the DB first — never point at the live state.db
+cp ~/.hermes/state.db /tmp/state_copy.db
+
+# 2. Find big lineages (sessions with parent_session_id form chains), then:
+python evals/compaction/scripts/reconstruct_lineage.py \
+    /tmp/state_copy.db <root_session_id> /tmp/lineage.json
+
+# 3. (optional) Replay a 500K prefix through one checkout's compressor and
+#    dump before/after for the HTML viewer:
+python evals/compaction/scripts/replay_lineage.py <checkout> /tmp/lineage.json out.json 500000
+python evals/compaction/scripts/build_html_report.py <runs_dir> report.html
+```
+
+`reconstruct_lineage.py` walks the whole descendant tree chronologically,
+dedupes rotation-copied rows by content hash, strips synthetic compaction
+artifacts (summaries, todo snapshots), and resolves the system prompt through
+the `system_prompts` dedup table (sessions only carry a hash). The HTML
+report renders before/after transcripts side by side with compaction
+artifacts color-coded.
+
+## Region-scoping tripwire
+
+`test_region_scoping.py` plants sentinels in head/middle/tail and asserts the
+summarizer's serialized-turns input carries ONLY the middle (compacted)
+region in both legacy and lean modes. Run it directly or via pytest.
+
+## Policies
+
+Defined in `policies.py`. Each policy maps to `ContextCompressor` constructor
+kwargs plus optional attribute overrides applied post-construction (e.g.
+`tail_token_budget`). Add new policies there — the runner picks them up by
+name.
+
+## Notes
+
+- Question generation and judging use `agent.auxiliary_client.call_llm`
+  (same transport the compressor uses), so the harness needs a configured
+  provider. Costs real tokens: ~(policies x questions) answer calls plus
+  one generation and one judge pass.
+- Accuracy is judged 2/1/0 (correct / partial / wrong); the scorecard
+  reports normalized percent. The judge sees gold answers, the answerer
+  does not.
+- `--also-uncompacted` adds a control arm that answers from the full
+  original transcript — the recall ceiling.

+each. "recovery" = one session_search round-trip (FTS5+BM25 sim) against the

+
+* sweep/gui current scores are from the previous question banks (same
+  transcripts; banks regenerated in the 4-way run). prmerge/acp are clean
+  same-bank comparisons across all arms.
+
+## Findings
+
+1. LEAN+RECOVERY BEATS CURRENT BY +22.5pts ON AVERAGE (68.3 vs 45.8) AT 3.3x
+   FEWER TOKENS (49K vs 162K). It wins on 3 of 4 transcripts and loses only
+   sweep — the one transcript where current's fat tail got lucky with
+   restated facts (93.3 is bank-inflated luck; see finding 3 of the previous
+   scorecard).
+
+2. THE ANCHOR INDEX FIXED THE NEEDLE-FACT CLASS. GUI closed-book went
+   23.3 -> 60.0 and GUI+recovery 46.7 -> 80.0 after mechanically indexing
+   exact identifiers (SHAs, ids, paths, error strings) instead of trusting
+   the summarizer with them. ACP+recovery hit 80.0.
+
+3. TWO FRESH TRANSCRIPTS CONFIRM CURRENT IS WEAK, NOT STRONG: 33.3 and 30.0
+   at ~157K retained. The original sweep 93.3 was restatement luck, not
+   policy quality. Current's average is 45.8% for 162K tokens — lean+recovery
+   is 22 points better for less than a third of the spend.
+
+4. prmerge IS THE HARD CASE for everyone (96.7 ceiling, best policy 43.3):
+   1.1M-token lineage truncated at 500K, dense multi-PR state. Recovery
+   misses there are mostly query formulation. Headroom, not a blocker.
+
+5. Goal check (Teknium): tail = max(10K, 2.5%) ✓; summaries scoped to the
+   compacted region only ✓ (sentinel tripwire test); session_search pointer ✓
+   (+20-43pts measured); better accuracy AND more savings than current ✓
+   (+22.5pts at 0.30x tokens).
+
+
+## Codex CLI head-to-head (same transcripts, same exams, same judge)
+
+Real OpenAI Codex CLI (v0.147.0, gpt-5.6-sol, 258K window) run end-to-end on
+the identical four transcripts: chunk files read via `codex exec` until its
+REAL auto-compaction fired (verified `compacted` event in the rollout jsonl;
+peak context 455-483K), then quizzed post-compaction from memory with the
+same 15-question banks and scored by the same judge.
+
+policy                  sweep   gui    prmerge  acp    AVG     retained state
+codex (real, post-cmp)  26.7%   40.0%  43.3%    36.7%  36.7%   ~4.5K (opaque blob + user msgs)
+hermes current          93.3%*  26.7%* 33.3%    30.0%  45.8%   ~162K
+hermes lean closed-book 40.0%   60.0%  23.3%    36.7%  40.0%   ~49K
+hermes lean+recovery    70.0%   80.0%  43.3%    80.0%  68.3%   ~49K
+
+Notes:
+- codex answers from its own post-compaction session — the honest analog of
+  our closed-book arms. It has NO session_search equivalent (its rollout is
+  on disk but the agent cannot search it at runtime), so recovery has no
+  codex counterpart; that gap is exactly the differentiator lean leans on.
+- Apples-to-apples closed-book: lean 40.0% vs codex 36.7% — parity-plus at
+  10x codex's retained state but 0.30x current's. With recovery: +31.6pts
+  over codex.
+- codex ties lean+recovery on prmerge (43.3%) — the dense multi-PR campaign
+  is the hardest transcript for every policy and the clearest iteration
+  target.
+- Methodology caveats: codex ingested transcripts as FILE READS (tool
+  outputs), not native conversation — this matches how its compaction
+  treats tool output (drops it all into the server-side summary) but is not
+  byte-identical to a native session. Its model (gpt-5.6-sol) also differs
+  from the answering model in our arms; scores compare COMPACTION PIPELINES
+  end-to-end, not models in isolation. One codex quiz reply was also
+  capped short (~1K chars for 15 answers), which its terse post-compaction
+  style invites.
+
+## Recommendation
+
+Ship lean as opt-in (compression.tail_mode: lean, legacy default), harness as
+the permanent gate. Iterate prmerge-class recall behind the flag (query
+mining, per-epoch anchor windows) before default flip.

+## Methodology notes
+
+- Transcripts: 4 real session lineages reconstructed from a state.db copy
+  (sweep campaign 42 rotations / GUI desktop 34 / PR-merge 17 / ACP review
+  17), chronological 500K-token prefix, tool-group aligned.
+- Question generation: main model, from the region the CURRENT policy would
+  summarize (most conservative boundary), cached per transcript so every
+  policy answers the identical exam.
+- Answering: fresh LLM sees ONLY the post-compaction context (closed-book) or
+  context + one FTS5+BM25 search round-trip over the archived region
+  (+recovery). Judge sees gold; answerer never does. Scoring 2/1/0.
+- Known caveats: 15 questions/transcript => +-1 question ~ 3.3pts noise;
+  sweep/gui current-policy rows predate a question-bank regeneration
+  (prmerge/acp are same-bank across all arms); the recovery sim conservatively
+  approximates production session_search (same engine, no windowing).
+- Cost shape: lean compaction = ~25 aux-model digest calls (~2min, one-time
+  per compaction) vs 1 call today; every post-compaction turn is ~110K input
+  tokens cheaper. Break-even ~1 turn.

+     naturally (verified via token_count drops / compacted events in the

+"""Disk-usage rollup for ``/api/status`` (NS-656).
+
+Companion to :mod:`gateway.memory_status`, closing the same class of gap
+for storage: a hosted agent can fill its data volume completely — SQLite
+writes failing, session persistence dead, config saves lost — while its
+dashboard and the NAS agent card both look perfectly healthy.  Fleet
+incidents OOF-2 (unrecoverable disk-full) and OOF-107 (fleet-wide disk
+exhaustion, remediated by hand) are exactly this failure mode.
+
+The readiness endpoint already probes disk (``gateway/readiness.py::
+_probe_disk``), but readiness is a component verdict, not user-facing
+telemetry — nothing renders it.  This module produces the public block
+the dashboard SPA and the NAS availability sweep actually consume.
+
+Unlike the memory block (which distills already-persisted heartbeat
+files), disk is sampled live via :func:`shutil.disk_usage` — a single
+``statvfs`` call, the same thing the readiness probe does per request.
+There is no meaningful "staleness" dimension, so no ``sampled_at``.
+
+Public-safety note: ``/api/status`` is an unauthenticated liveness probe
+(``PUBLIC_API_PATHS``).  This block carries only coarse numbers (MB
+granularity, whole-percent usage) and an enum — the same disclosure
+class as the ``memory`` block.
+
+Everything is best-effort and read-only: an unreadable filesystem
+degrades to ``pressure="unknown"`` rather than raising into the status
+endpoint.

+gateway's scheduled deliveries. In strict/allowlisted enterprise deployments
+that divergence silently dropped attachments from manual cron runs while
+scheduled runs delivered them (text is unaffected — only media goes through
+path validation).
+
+``apply_media_policy_env()`` is that same translation as a shared, idempotent
+helper. Gateway startup calls it, and every standalone delivery entrypoint
+calls it immediately before filtering media paths.
+
+Precedence: an explicitly-set environment variable WINS over config.yaml.
+This preserves both the operator contract (env overrides are how deployments
+pin behavior) and gateway/run.py's historical shape (it only wrote the env

+"""Memory status rollup for ``/api/status`` (NS-656).
+
+The gateway already *produces* every memory-pressure signal a user would
+want to know about, but all of it dies in log files:
+
+* :func:`gateway.shutdown_watchdog.write_loop_heartbeat` embeds a
+  :func:`gateway.lifecycle_ledger.sample_memory` snapshot (gateway RSS +
+  system MemAvailable/MemTotal + swap) in ``state/gateway.heartbeat``
+  every 30 seconds.
+* :func:`gateway.lifecycle_ledger.record_startup` detects an unclean
+  previous death and flags ``suspected_oom`` — but only into
+  ``gateway-exit-diag.log`` and a WARNING line.
+* ``gateway/agent_cache_pressure.py`` evicts transcripts under pressure,
+  again log-only.
+
+So a hosted agent can be OOM-killed hourly (the BlueAtlas incident,
+NS-608) while its dashboard and the NAS agent card both look perfectly
+healthy.  This module is the read side that closes the gap: it distills
+the *already-persisted* heartbeat + lifecycle sentinel into a compact,
+public-safe block that ``/api/status`` can serve to the dashboard SPA
+and the NAS availability sweep — no new sampling, no IPC with the
+gateway process, just two small file reads.
+
+Public-safety note: ``/api/status`` is an unauthenticated liveness probe
+(``PUBLIC_API_PATHS``), which is exactly why NAS can consume it.  This
+block therefore carries only coarse numbers (MB granularity), enums, and
+booleans — the same disclosure class as the existing ``active_agents``
+count and ``nous_session_valid`` field (which was added for the same
+NAS-sweep audience).
+
+Everything here is best-effort and read-only: a missing/corrupt file
+degrades to ``pressure="unknown"`` rather than raising into the status
+endpoint.

+"""Dependency install execution shared between early recovery and full recovery.

+  ``hermes_cli.main``'s third-party imports, so it can complete a pending
+  update while no native extension is mapped yet (#83569).
+- ``hermes_cli.main._recover_core_update_marker_locked`` — the historical
+  post-import recovery path. Kept as a fallback for installs the early pass
+  could not complete (marker left in place on failure).
+
+This module is deliberately **stdlib-only** so importing it can never fail in
+the corrupted-venv state it exists to repair. ``hermes_cli.main`` imports
+``managed_uv``, ``hermes_constants``, and friends only in its late path; the
+early path must not. Where the late path uses ``managed_uv.ensure_uv`` to
+bootstrap uv if missing, the early path uses the stdlib
+:func:`hermes_cli._early_recovery._find_uv_binary` lookup and falls back to
+plain pip when uv is absent — a degraded but working installer (the late

+    ``"ignore"``), and the hidden-window ``creationflags`` on Windows only. On

+    with nothing behind it — during ``hermes import``, which is the
+    disaster-recovery path a user reaches for *because* they already lost

+
+    ``atomic_replace`` rather than a bare ``os.replace``: it resolves a
+    symlinked target first, so a deployment that links ``config.yaml`` into a
+    dotfiles repo keeps the link instead of having it silently swapped for a
+    regular file (GitHub #16743), and it falls back to copy/fsync/unlink on
+    ``EXDEV``/``EBUSY`` for cross-device and bind-mount installs.  That

+
+    Permission bits *and* ownership are carried across the replace so routing
+    through mkstemp does not change the file the caller would otherwise have
+    produced.  ``os.replace`` swaps in a temp file owned by the *writing* user,
+    so without the chown a ``sudo hermes import`` would silently re-own every
+    restored file to root — on the disaster-recovery path, and on exactly the
+    Docker/NAS installs ``utils._restore_file_owner`` documents.  Both concerns
+    delegate to the shared ``utils`` helpers rather than being re-derived here.
+    The temp file is removed on any failure so a partial import leaves no
+    residue.
+
+    The one bit of the old file *not* carried across is setuid/setgid.  The
+    replacement bytes come out of the zip, so preserving those would let an
+    archive take over the identity an existing privileged file executes as —
+    and unlike the other ``utils`` writers, which re-serialize content this
+    process produced, the trust boundary here is an untrusted archive.  The

+Password providers ride the same broker with step 2 swapped: there is no
+upstream IDP, so ``/auth/native/authorize`` sends the system browser to the
+interactive ``/login`` form (broker_state in the PKCE cookie) and a successful
+``/auth/password-login`` plays the role of the upstream callback — it calls
+:func:`complete_pending` and bounces the browser to the loopback redirect.
+Steps 4–5 are identical. The point of brokering a password login at all is

+Passwords, etc.), which no embedded desktop webview can.

+
+Sources (read-only — foreign files are never modified):

+
+* **Codex CLI** stores rollout JSONL under
+  ``~/.codex/sessions/YYYY/MM/DD/rollout-*.jsonl``.  The first line is a
+  ``session_meta`` record (cwd, session id); conversation turns are
+  ``response_item`` records whose payload is ``{"type": "message",

+role-alternation invariant Hermes enforces everywhere else:
+
+* only plain ``user`` / ``assistant`` text messages are produced (tool
+  calls become short bracketed summaries inside the assistant text; we
+  never fabricate ``tool_calls`` structures);

+# the full drain budget (180s by default), warns "still running after 180.0s
+# — restart may fail", and `hermes update` can deadlock behind it.  The loop
+# publishes a liveness signal precisely for this case: an asyncio task
+# rewrites ``state/gateway.heartbeat`` every 30s (#66892), so a frozen loop
+# stops refreshing the file while a busy-but-alive loop keeps refreshing it.
+#
+# ``probe_gateway_loop_liveness`` reads that signal (a local stat + JSON read,
+# instant — far inside the 10s query tier of the subprocess timeout doc) and

+# - ``alive``   — heartbeat is fresh: the loop is dispatching (possibly busy).
+#                 Callers must take the normal graceful-drain path, which
+#                 honours the in-flight cron drain floor (#86684).
+# - ``wedged``  — heartbeat belongs to this PID but has gone stale well past
+#                 several missed beats: the loop is provably dead.  Draining
+#                 is pointless (nothing can run the drain), so callers may
+#                 escalate immediately via ``_escalate_wedged_gateway``.
+# - ``unknown`` — no heartbeat / unreadable / PID mismatch (older gateway,

+#                 Treated like ``alive``: never escalate on ambiguity.

+* :func:`is_ancestor_of_head` — ask whether a remote tip is already contained

+"""Recurring in-session wakeups — the /loop command (Claude Code parity).
+
+``/loop [interval] <prompt>`` re-runs a prompt (or a slash command) on a
+recurring cadence INSIDE the current session. Each tick is a real agent
+turn: the wakeup prompt is injected through the exact same input path as
+a typed user message, so the agent always sees current state (latest CI
+result, newest queue depth, the file as it is now).
+
+Two cadence modes, mirroring Claude Code's ``/loop``:
+
+- **Fixed interval** — ``/loop 5m check the deploy`` fires every 5 minutes.
+- **Self-paced** — ``/loop keep refining the failing test until green``
+  (no interval token) lets the loop set its own rhythm: it starts fast and
+  backs off exponentially while the agent's replies stop changing, then
+  snaps back to the floor as soon as a reply differs. Zero extra LLM cost —
+  change detection is a local digest comparison.
+
+Stop conditions (any of):
+
+- The agent ends a wakeup reply with ``LOOP_COMPLETE`` on its own line
+  (the wakeup prompt teaches it to do so when the task is done/moot).
+- ``--times N`` — stop after N ticks.
+- ``--until <condition>`` — an evidence-based stop judged by the same
+  auxiliary judge that powers /goal (fail-open: a broken judge never
+  wedges the loop; the tick budget is the backstop).
+- ``/loop stop`` / ``/loop clear`` — user control.
+- ``loops.max_ticks`` config backstop (default 100, 0 = unlimited).
+
+Design notes / invariants (same contract as ``hermes_cli/goals.py``):
+
+- A wakeup is just a normal user-role message appended via the surface's
+  ordinary input path. No system-prompt mutation, no toolset swap —
+  prompt caching stays intact and role alternation is preserved.
+- Wakeups only fire while the session is IDLE. A real user message always
+  wins; the tick just re-arms and fires at the next idle boundary.
+- State is persisted in SessionDB's ``state_meta`` table keyed by
+  ``loop:<session_id>`` so ``/resume`` picks the loop back up.
+- /goal mixing: an active /goal takes priority. When the goal loop has a
+  continuation queued (or the goal judge is mid-flight), the /loop tick
+  defers to the next interval instead of racing a second synthetic turn.
+  Goal-continuation turns never count as loop ticks and vice versa.
+- This module has zero hard dependency on ``cli.HermesCLI``, the gateway
+  runner, or the TUI gateway — all three drive the same ``LoopManager``.

+"""Data-policy confirmation helpers for model selection surfaces.
+
+Some inference tiers are cheap *because* the vendor trains future models on your
+prompts and completions. Selecting one for the low price without realising the
+data trade-off is a real footgun. This guard mirrors
+``hermes_cli.model_cost_guard`` — it returns a warning payload that the CLI and
+web model-selection flows surface as an explicit confirm step.
+
+Why a static table (not a ProviderProfile hook): the guard runs inside core
+selection code (``auth.py`` / ``web_server.py``), which never calls into the
+active provider profile for a selection-time warning. Keeping the rule set here
+also means it renders regardless of which provider plugin happens to be loaded,
+and it stays testable without importing arbitrary third-party plugin code into
+the selection path.
+
+The status is NOT machine-readable anywhere today: neither models.dev nor the
+Meta ``/v1/models`` payload exposes a training/retention flag (verified
+2026-08-07). The only reliable signals are the vendor-documented model id and
+its anomalously low pricing, so the rule keys on the id.

+"""Unified selection-time guard registry for model switching surfaces.

+every new guard class (e.g. the data-training-tier guard) had to be wired into
+every surface by hand — and inevitably missed some.

+result with their own confirm UX (stdin prompt, modal, inline keyboard,
+``confirm_required`` JSON) — that half stays per-surface; the *evaluation* half
+lives here. Adding a guard to ``_GUARDS`` makes it appear on every surface at
+once.
+

+
+        A platform plugin can ship two independent things: an inbound adapter

+        agent calls like any other tool. Deferring the plugin defers both, so
+        in a CLI/TUI process the client tools never register at all:
+        ``resolve_toolset()`` returns ``[]``, the toolset is missing from the
+        ``hermes tools`` checklist, and even an explicit ``platform_toolsets``
+        entry is dropped because the key is unknown. The same tools work in
+        gateway/web processes only because those materialize every platform at
+        startup (issue #78050).
+
+        Client tools that live in a dedicated ``tools`` submodule can be
+        registered at discovery time instead: importing ``<plugin>/tools.py``
+        does not import the adapter, so the SDK stays unloaded and startup
+        stays cheap. A plugin taking this path must therefore keep its package
+        ``__init__`` import-light and pull the adapter in from inside
+        ``register()`` (as ``plugins/platforms/a2a`` does).
+
+        Opting in is explicit: the manifest must declare ``provides_tools``
+        (the field the plugin list and web server already read to name a
+        plugin's tools, per #78538). Keying off the mere presence of a
+        ``tools.py`` would opt a plugin in by accident — a platform is free to
+        put internal helpers there — and would leave the contract invisible to
+        anyone reading the manifest. ``tools.py`` remains where the code is

+
+    When the terminal is in ``modifyOtherKeys=2`` mode (pushed by
+    ``_enable_extended_enter_keys`` so Shift+Enter is distinguishable from
+    Enter), the terminal re-encodes *every* Ctrl+key combo as
+    ``ESC[27;5;<codepoint>~`` instead of the raw control byte (``\\x01`` etc.).
+    Kitty keyboard protocol emits ``ESC[<codepoint>;5u``.
+
+    Stock prompt_toolkit 3.x only maps ``ESC[27;5;13~`` (Ctrl+Enter = Ctrl+M);
+    all other Ctrl+letter combos are unmapped and leak as literal text or get

+      → ``Keys.ControlA`` .. ``Keys.ControlZ``
+    * **Ctrl+digit** (0–9): same formats → ``Keys.Control0`` .. ``Keys.Control9``
+    * **Ctrl+symbol** (``[`` ``\\`` ``]`` ``^`` ``_`` `` `` ``@``):
+      same formats → the same ``Keys`` value the raw control byte maps to.
+    * **Alt+letter** (a–z, A–Z): ``ESC[27;3;<codepoint>~`` and
+      ``ESC[<codepoint>;3u`` → ``(Keys.Escape, <letter>)`` — matching how
+      prompt_toolkit handles a bare ``ESC`` followed by a character.
+    * **Shift+letter** (a–z): → the uppercase character.
+    * **Multi-modifier letters** (Shift+Alt=4, Ctrl+Shift=6, Ctrl+Alt=7,
+      Ctrl+Alt+Shift=8): normalized onto the same targets — Ctrl-bearing
+      combos behave as the Ctrl key (Alt adds an ``Escape`` prefix),
+      matching how dte/kakoune normalize these protocols.
+    * **Esc key**: ``ESC[27u`` / ``ESC[27;<mod>u`` (Kitty disambiguate mode
+      reports Esc this way, #56684) → ``Keys.Escape``.
+    * **Modified Enter/Tab/Backspace/Space**: Alt+Enter → the Alt+Enter
+      newline tuple; Shift+Tab → ``BackTab``; Ctrl+Tab → plain Tab;
+      Ctrl/Alt+Backspace → ``(Escape, ControlH)`` (backward-kill-word,

+      backspace; Shift+Space → a plain space (#86866); Alt+Space →
+      ``(Escape, " ")``.
+    * **Kitty functional keys** (Private Use Area codepoints): keypad keys
+      → their non-keypad equivalents (KP_ENTER → Enter, KP_4 → '4',
+      KP_LEFT → Left, …); F13–F24 → ``Keys.F13``..``F24``; lock/media/
+      modifier-event keys → ``Keys.Ignore`` so they are consumed instead of

+"""``hermes peer`` — bot-to-bot DMs across machines/gateways.
+
+A *peer* is another Hermes gateway (any machine: homelab, Spark, Hermes
+Cloud) running the ``api_server`` platform. Registering it here gives every
+bot on THIS machine a transport to message bots on THAT machine:
+
+    hermes peer add spark --url http://spark.lan:8377 --key <API_SERVER_KEY>
+    hermes peer dm spark "Message from 🤖 dixie (@dixie): disk status?"
+    hermes peer dm spark/researcher "..."      # named profile (multiplexed peer)
+
+``dm`` resolves the remote agent's canonical "Bot Chat" session (by title,
+creating it when missing), runs ONE synchronous agent turn over the peer's
+existing ``POST /api/sessions/{id}/chat`` endpoint, and prints the reply on
+stdout — the exact cross-machine twin of the local
+``hermes -p <bot> chat --in ~ -c "Bot Chat" ...`` bot-messaging command, so
+the Bot Mode protocol composes over it unchanged.
+
+Design notes:
+- No new server surface: the peer's stock api_server is the transport.
+- Peer labels/URLs live in config.yaml (``bot_peers``); the peer's
+  API_SERVER_KEY is a credential and lives in ``~/.hermes/.env`` as
+  ``HERMES_PEER_<NAME>_KEY``.
+- Named-profile targets use the peer's ``/p/<profile>/`` multiplex mirror;
+  the bare target is the peer gateway's own (launch) profile.

+"""Per-terminal session breadcrumbs for ``hermes -c`` / ``--continue``.
+
+Each CLI session writes a tiny breadcrumb file
+``$HERMES_HOME/terminal-sessions/<terminal-id>`` containing
+``{"session_id": ..., "cwd": ..., "ts": ...}``.  A bare ``hermes -c`` then
+resumes the session that belongs to THIS terminal (tty / tmux pane / kitty
+window / wezterm pane / ...) instead of the globally most-recent session —
+so two terminals side by side each continue their own conversation.
+
+Everything here is strictly best-effort: no function raises, and when no
+stable terminal identity can be derived (no tty and no known multiplexer
+env var) breadcrumbs are skipped entirely and ``-c`` falls back to the
+existing latest-session behavior.  Gated by ``session.terminal_continue``

+# draw-your-font
+
+Photo of handwritten letters in → installable font out. You do the seeing
+(find and label letters, judge quality); the CLI does all geometry (trace,
+metrics, font assembly). Never edit SVG paths or coordinates yourself.
+
+## Setup in Hermes (once per session)
+
+The CLI is the pinned npm package `draw-your-font@0.1.0` — run it via npx (Node ≥ 18 required, no global install needed):
+
+```bash
+npx -y draw-your-font@0.1.0 --help
+```
+
+Wherever the examples below show `$DYF`, use `npx -y draw-your-font@0.1.0`. Shell variables do not persist between tool calls, so paste the full command each time. Everything runs locally; the user's handwriting never leaves the machine.
+
+Photos arrive in Hermes either as a file path in the message or via the gateway image cache — use the actual file path with the CLI. When a photo lands in the conversation with no path, ask the user for the file (the CLI needs a real file, not your memory of the image).
+
+Do the visual steps (contact sheets, previews, glyph sheets) by loading the PNGs with `vision_analyze`.
+
+## Decide the flow
+
+- **User has no photo yet** → offer the template: print, write, photograph.
+- **User shares photo(s) of handwriting** → main flow below.
+- **User pasted an image but there is no file path** → you can see it, but the
+  CLI needs a file. Ask them to drag the image file into the terminal (that
+  inserts its path) or give the path directly. Do not proceed from memory.
+- **User wants changes to a font built this session** → Refine section.
+
+## Template flow (best quality)
+
+```bash
+$DYF template -o template.pdf --charset minimal   # or: spanish
+```
+
+Tell the user: print it, write one character per box with a dark pen
+(0.5 mm+), keep the letter sitting on the solid line, then photograph each
+page from above in good light and share the file paths. The grid prints in
+light grey and vanishes during processing - only their ink survives.
+
+## Main flow: photo(s) → font
+
+**1. Segment.** Works for template pages and freeform photos alike:
+
+```bash
+$DYF segment photo1.jpg photo2.jpg -d work
+```
+
+**2. Look, then label.** Load `work/contact-1.png` with `vision_analyze` (one per photo): every
+detected blob is numbered. This is the step where your eyes matter - check:
+
+- Did every written character get exactly one box? A letter drawn with
+  separate strokes may appear as two boxes (relabel handles it: give the main
+  box the character and mark the fragment `""`), and two touching letters may
+  share one box (ask the user to re-shoot just those, or accept the gap).
+- Junk boxes (shadows, ruled lines, smudges, page edges) → label them `""`.
+
+Then write `work/labels.json` mapping blob id → character, e.g.
+`{"0": "A", "1": "B", "7": "", "8": "a"}`:
+
+- Template page: order is the charset order printed on the template - verify
+  against the sheet instead of trusting it blindly. minimal order: A–Z, a–z,
+  0–9, then `.,;:!?'"-()@#&+/$`; spanish appends `ÑñÁÉÍÓÚáéíóúü¿¡`.
+- Freeform: identify each letter from the contact sheet. Uppercase vs
+  lowercase for shape-twins (S/s, O/o, C/c, X/x…) is decided by relative size
+  and position - compare against neighbors you're sure of.
+- The user told you what they wrote (e.g. "ABC then abc")? Trust it, map in
+  reading order (top row first, left to right), and verify visually.
+- Same letter appears twice → label the better-drawn one, `""` the other.
+
+**3. Build.**
+
+```bash
+$DYF build -d work --labels work/labels.json --name "Dan's Hand"
+```
+
+Name the font after the user (ask if unclear - one short question max).
+
+**4. Judge before delivering.** Load `work/preview.png` and `work/glyphs.png` with `vision_analyze`
+and critique like an art director:
+
+- Broken or blotchy letters (bad trace) → often a faint pen stroke; try
+  `--weight 1`, or ask for a re-shoot of just that letter.
+- Everything too thin/thick → rebuild with `--weight 1` / `--weight -1`.
+- Jagged edges → rebuild with `--smooth 1.5` (up to 2).
+- A letter placed wrong (e.g. a `g` not descending) → usually a mislabel;
+  fix labels.json and rebuild.
+- Filled-in bowls (b, o, g look solid): should never happen - if it does,
+  the crop is smudged; ask for a re-shoot.
+
+Rebuilds are cheap and safe to iterate. Fix what you can yourself first;
+only bother the user for re-shoots when the source ink is the problem.
+
+**5. Deliver.** The font lands at `<workdir>/<NameWithoutSpaces>.ttf` (the
+build output prints the exact path). Give that path and how to install:
+macOS - double-click → "Install Font"; Windows - right-click → "Install".
+Mention what's missing (the build prints uncovered letters) and offer,
+without pushing:
+
+- Web formats + CSS: rebuild with `--formats ttf,woff,woff2,css`.
+- A legibility read (below).
+- Their next photo to fill missing characters: re-run segment with ALL
+  photos (old and new) into a fresh workdir - `$DYF segment p1.jpg p2.jpg -d
+  work2` - then relabel from the new contact sheets (blob ids renumber; the
+  old labels.json does not carry over) and build from the new workdir.
+
+## Refine (conversational iteration)
+
+| User says | Do |
+|---|---|
+| "smoother / rounder" | `build … --smooth 1.5` (max 2) |
+| "thicker / bolder" | `build … --weight 1` (max 2) |
+| "thinner / lighter" | `build … --weight=-1` (negative needs the `=` form) |
+| "the g looks bad" | show them `work/crops/<id>.png` for that letter; offer re-shoot or smooth |
+| "wrong letter" / swap | edit labels.json, rebuild |
+| "give me woff2 / web" | `build … --formats ttf,woff,woff2,css` |
+| custom preview text | `$DYF preview -d work --text "…"` (after a build) |
+
+All refine commands rebuild from the stored crops - no re-photographing
+needed unless the ink itself is the problem.
+
+## Legibility report (offer after delivering)
+
+```bash
+$DYF preview -d work --text "minimum mill rn m cl d I l 1 O 0 quick brown fox" -o work/legibility.png

+
+Read it and give an honest, kind read: a score out of 10 for body-text use,
+the 2–3 letter pairs most likely to confuse (rn→m, cl→d, I/l/1, O/0), and one
+or two concrete fixes (rewrite those letters larger, more spacing). Note that
+display use (headings, notes) is more forgiving than paragraphs. Never gate
+delivery on this - it's advice, not a blocker.

+# Troubleshooting capture & segmentation
+
+The binarizer is adaptive (local background estimate) with two knobs on
+`segment`/`make`:
+
+- `--delta N` (default 40): how much darker than the local paper a pixel must
+  be to count as ink. Lower = more sensitive (catches faint pens, also more
+  noise). Raise to 55–70 for photos with heavy shadows misread as ink.
+- `--cap N` (default 165): absolute grey ceiling for ink after contrast
+  normalization. Anything lighter is never ink - this is what erases the
+  template's grey guides. Lower to 140 if printed guides survive into blobs;
+  raise to 190 for a very faint pencil (expect more noise).
+
+Re-running segment rewrites blobs.json and renumbers every blob - discard
+any labels.json written earlier and relabel from the fresh contact sheet
+(prefer a fresh `-d` workdir).
+
+## Symptoms → fixes
+
+**Hundreds of tiny blobs** - noisy paper texture or aggressive delta. Re-run
+segment with `--delta 55`. If the photo is low light, ask for a brighter shot.
+
+**A huge blob spanning the page** - a shadow edge or the page border got
+thresholded. Crop the photo to just the paper (or re-shoot from directly
+above), or raise `--delta`.
+
+**Letters missing entirely** - pen too faint (pencil, gel on glossy paper).
+Try `--delta 25 --cap 190`. If still missing, the honest fix is rewriting
+with a darker pen; say so.
+
+**Strokes broken into fragments** - thin ballpoint. Try `--delta 30`, then
+`build --weight 1` to fatten what traced. Recommend a 0.5mm+ pen for the
+re-shoot.
+
+**Two letters in one box** - they touch on paper. No code fix; ask the user
+to re-write just those letters with space between them, segment the new
+photo, and merge via labels.
+
+**Template guides appear as blobs** - printer printed the grey too dark.
+Re-run with `--cap 140`. If their printer only does solid black, they can
+still use the template - the guides will show as long thin blobs; label them
+all `""`.
+
+**i/j dots detached as separate blobs** - normally auto-merged; if the dot is
+very far from the stem it may not be. Label the stem blob with the letter and
+the dot `""` - or better, relabel both after a re-shoot. (A dotless i still
+reads fine in most handwriting.)
+
+**Rotated/skewed photo** - mild angles are fine and become part of the font's
+character. A strongly rotated photo (>5°) will slant every glyph; ask for a
+straighter shot rather than trying to compensate.

+## Cleanup
+
+`render` is one-shot (workers exit when it finishes). `preview` is **not** — it runs a background Next.js server that keeps Chrome workers resident until you stop it. Never leave one running: on GPU-less hosts each idle worker's swiftshader process pegs a CPU core, and a preview left open for days stacks up multiple.
+
+Stop a preview when the user is done reviewing (or before starting a new one):
+
+```bash
+pkill -f "hyperframes.*preview"     # the Studio server (frees port 3002)
+pkill -f chrome-headless-shell      # its render workers; only safe if nothing else uses them
+```
+
+If unsure whether other tools use `chrome-headless-shell`, check first: `pgrep -af chrome-headless-shell`. Recover a wedged host (many idle workers spinning CPU) the same way — see [references/troubleshooting.md](references/troubleshooting.md#runaway-cpu-from-leftover-preview-workers).
+
 ## Pitfalls
 
+- **Leaving `preview` running** — it's a long-lived server holding Chrome workers; on WSL/containers/CI those idle workers spin a CPU core each (software WebGL). Stop it when done — see [Cleanup](#cleanup).
+
 - **`HeadlessExperimental.beginFrame' wasn't found`** — Chromium 147+ removed this protocol. Ensure you're on `hyperframes@>=0.4.2` (auto-detects and falls back to screenshot mode). Escape hatch: `export PRODUCER_FORCE_SCREENSHOT=true`. See [hyperframes#294](https://github.com/heygen-com/hyperframes/issues/294) and [references/troubleshooting.md](references/troubleshooting.md).
 - **System Chrome (not `chrome-headless-shell`)** — renders hang for 120s then timeout. Run `npx puppeteer browsers install chrome-headless-shell` (setup.sh does this). `hyperframes doctor` reports which binary will be used.
 - **`repeat: -1` anywhere** — breaks the capture engine. Always compute a finite repeat count.

+## Runaway CPU from leftover preview workers
+
+**Symptom:** load average climbs and stays high; `top` shows several `chrome-headless-shell --type=gpu-process` at ~300%+ CPU each, alive for hours/days, even when you're not rendering.
+
+**Cause:** `npx hyperframes preview` is a long-lived server that keeps Chrome render workers resident. On hosts with no real GPU (WSL, containers, most CI), each idle worker falls back to software WebGL (`swiftshader`) whose GPU process busy-spins a CPU core. A preview left open — or several started over time — stacks these up.

+**Diagnose:**
+
+```bash
+pgrep -af chrome-headless-shell        # list the workers + their parent flags
+pgrep -af "hyperframes.*preview"       # the preview server(s) holding them open

+
+**Fix:** stop the preview server and its workers (see [SKILL.md#cleanup](../SKILL.md)):
+
+```bash
+pkill -f "hyperframes.*preview"
+pkill -f chrome-headless-shell         # only if no other tool uses it — check pgrep first
+```
+
+**Avoid:** never leave a `preview` running after review; use `render` (one-shot, self-cleaning) for output. Keep `--workers` low on shared/GPU-less hosts.

+
+# Simple English: Write Like an Aerospace Manual
+
+Write technical text with the rules of ASD-STE100 Simplified Technical English. STE is the controlled language that aerospace and defense manufacturers use for maintenance documentation. The rules exist so that a tired reader who is not a native English speaker cannot misread an instruction. They remove the usual signs of AI-generated text as a side effect: long sentences, synonym rotation, hedges, filler, and decorative clauses.
+
+Write for that tired reader. Each sentence must survive one read.
+
+## How to use it in Hermes
+
+The text usually arrives one of three ways:
+
+1. **Inline.** The user pastes the text into the message. Rewrite it in place and reply with the result.
+2. **File.** The user points at a file (README, runbook, docs page). Use `read_file` to load it, then `patch` for targeted section rewrites or `write_file` for a full rewrite. Never touch code blocks, identifiers, or quoted errors (see Untouchables).
+3. **Check mode.** The user asks you to audit text for STE compliance instead of rewriting it. Report each violation as rule number + offending text + compliant rewrite, using `references/checklist.md`.
+
+This skill differs from `humanizer`: humanizer restores natural human voice; simple-english enforces a controlled language for technical instructions. For docs, runbooks, and error messages use this skill. For blog posts, essays, and personal writing use humanizer. Do not apply both to the same text.
+
+## Your Task
+
+When asked to write or rewrite technical text:
+
+1. **Select the mode** (pragmatic or strict, below).
+2. **Classify each passage** as procedural or descriptive. Every other rule depends on this.
+3. **Correct your vocabulary before drafting.** In strict mode, use `make sure that` for the check/verify/confirm/ensure concept — the dictionary rejects all four as verbs. In pragmatic mode, pick one and keep it. Pick ONE noun for config/settings (all are valid technical nouns — pick one and keep it). Use no other word for these concepts in the whole document.
+4. **Apply the rules** from the catalog below.
+5. **Do the self-check** before you deliver. This step is not optional.
+6. **Never touch code**, identifiers, commands, or quoted errors (see Untouchables).
+
+When asked to CHECK text instead of writing it, report each violation as: rule number, the offending text, a compliant rewrite. Cite only rule numbers that exist in this file. Do not cite rule numbers from memory: the numbering is unintuitive and models invent it (tested — an agent without this file cited "Rule 3.1: short sentences"; the real Rule 3.1 is about verb forms).
+
+## Two Modes
+
+| Mode | When | What you apply |
+|---|---|---|
+| **Pragmatic** (default) | Docs, READMEs, error messages — the user wants clear text | All structural rules. Domain words stay ("idempotent", "webhook"). |
+| **Strict** | The user names STE, ASD-STE100, or compliance | Structural rules + full vocabulary discipline, and tell the user that full compliance needs the official dictionary (free at asd-ste100.org). |
+
+## Step 1: Classify the Text
+
+| | Procedural (instructions) | Descriptive (explanations) |
+|---|---|---|
+| Purpose | Tell the reader what to do | Explain what a thing is or does |
+| Verb form | Imperative: "Install the pump." | Simple present/past/future |
+| Sentence limit | **20 words** (Rule 5.1) | **25 words** (Rule 6.3) |
+| Unit rule | One instruction per sentence (5.2) | One topic per paragraph (6.5), max six sentences per paragraph (6.6) |
+
+Do not mix the two in one passage. A "Getting started" section is procedural. An "Architecture" section is descriptive. A note inside a procedure is descriptive (25-word limit, no imperative).
+
+## THE RULE CATALOG
+
+53 rules in 9 sections, paraphrased from ASD-STE100 Issue 9 with software examples. The official wording is in the free standard at asd-ste100.org.
+
+### Section 1 — Words (Rules 1.1-1.14)
+
+| Rule | Instruction |
+|---|---|
+| 1.1 | Use only approved words, technical nouns, or technical verbs. |
+| 1.2 | Use an approved word only as its listed part of speech. |
+| 1.3 | Use an approved word only with its approved meaning. |
+| 1.4 | Use only the approved forms of verbs and adjectives. |
+| 1.5 | You can use domain words as technical nouns ("webhook", "commit", "endpoint"). |
+| 1.6 | Use an unapproved word only when it is a technical noun or part of one. |
+| 1.7 | Do not use technical nouns as verbs. |
+| 1.8 | Use the technical nouns of your project or industry. |
+| 1.9 | When you pick a technical noun, pick a short and clear one. |
+| 1.10 | No regional, slang, or jargon words as technical nouns. |
+| 1.11 | One item, one name. Do not call it "config" here and "settings" there. |
+| 1.12 | You can use domain verbs as technical verbs ("deploy", "compile", "merge"). |
+| 1.13 | Do not use technical verbs as nouns. |
+| 1.14 | Use American English spelling. |
+
+In pragmatic mode, rules 1.5, 1.8, and 1.12 do the heavy lifting: your domain vocabulary is legal. The ones agents break are 1.7, 1.11, and 1.13.
+
+**Before:** You can webhook the event, then do a deploy.
+**After:** Send the event to the webhook. Then deploy the service.
+
+### Section 2 — Multi-word nouns (Rules 2.1-2.2)
+
+| Rule | Instruction |
+|---|---|
+| 2.1 | Write multi-word nouns of three words or fewer. |
+| 2.2 | When a technical noun needs more than three words, write it in full once, then give a short form or hyphenate the units. |
+
+Break long noun chains with prepositions (of, on, in, for):
+
+**Before:** the connection pool timeout configuration value
+**After:** the timeout value for the connection pool
+
+### Section 3 — Verbs (Rules 3.1-3.7)
+
+| Rule | Instruction |
+|---|---|
+| 3.1 | Use only the verb forms that the dictionary gives. |
+| 3.2 | Use only: infinitive, imperative, simple present, simple past, simple future, past participle as adjective. |
+| 3.3 | Use the past participle only as an adjective ("the cached response"). |
+| 3.4 | No auxiliary verbs for complex constructions. No present perfect, no "is to be installed". |
+| 3.5 | Use an "-ing" form only as a technical noun or inside one ("logging", "the mounting bracket") — never as a verb. |
+| 3.6 | Active voice. In descriptive text, passive is legal only when the agent is unknown. |
+| 3.7 | Describe an action with a verb, not a noun ("compress the file", not "perform compression of the file"). |
+
+**Approved modals: can, will, must. Banned: should, would, may, might, could (Rule 3.2).**
+The standard rejects "could" even for possibility: write "an explosion can occur", never "could occur". For "should": a requirement becomes "must"; a suggestion is stated as fact or deleted. This matters double for agent instructions — models read "should" as optional.
+
+**Before:** The migration has completed and the table is being rebuilt.
+**After:** The migration is complete. The database rebuilds the table.
+
+**Before:** The flag can be set in the config file, making restarts unnecessary.
+**After:** You can set the flag in the config file. Then a restart is not necessary.
+
+**Before:** The temperature must be adjusted.
+**After:** Adjust the temperature.
+
+### Section 4 — Sentences (Rules 4.1-4.5)
+
+| Rule | Instruction |
+|---|---|
+| 4.1 | Write short and clear sentences. |
+| 4.2 | Do not omit words or use contractions to shorten sentences. Keep articles, keep "that". |
+| 4.3 | Use a vertical list for complex text. |
+| 4.4 | Use connecting words between sentences on related topics ("Then", "As a result"). |
+| 4.5 | Put an article (the, a, an) or a demonstrative adjective (this, these) before nouns where applicable. |
+
+Rule 4.2 is the anti-terseness rule. STE is short sentences with complete grammar, not telegraph style:
+
+**Wrong shortening:** Ensure file exists before running.
+**STE:** Make sure that the file exists before you run the command.
+
+### Section 5 — Procedural writing (Rules 5.1-5.5)
+
+| Rule | Instruction |
+|---|---|
+| 5.1 | Maximum 20 words per sentence. Warnings and cautions included. |
+| 5.2 | One instruction per sentence, unless two actions happen at the same time. |
+| 5.3 | Write instructions in the imperative: "Run the migration." |
+| 5.4 | Put a required condition before the command, divided by a comma: "If the build fails, read the log." |
+| 5.5 | Notes give information, never instructions. Notes get the 25-word limit. |
+
+**Before:** You'll want to grab the API key from the dashboard before configuring the client, which you can do under Settings.
+**After:** Get the API key from the dashboard, under Settings. Then configure the client with this key.
+
+### Section 6 — Descriptive writing (Rules 6.1-6.6)
+
+| Rule | Instruction |
+|---|---|
+| 6.1 | Give information gradually: one new fact per sentence. |
+| 6.2 | Use key words and phrases to give the text a logical structure. |
+| 6.3 | Maximum 25 words per sentence. |
+| 6.4 | Group related information in paragraphs. |
+| 6.5 | One topic per paragraph. |
+| 6.6 | Maximum six sentences per paragraph. |
+
+No imperative in descriptive text. Descriptions explain; procedures instruct.
+
+### Section 7 — Safety instructions (Rules 7.1-7.3)
+
+| Rule | Instruction |
+|---|---|
+| 7.1 | Use a word that shows the risk level ("WARNING" = injury, "CAUTION" = damage). |
+| 7.2 | Start with a clear command or condition. |
+| 7.3 | Then give the risk or the possible result. |
+
+Never bury the instruction after the explanation. The pattern transfers directly to destructive CLI flags, irreversible migrations, and dangerous API options.
+
+**Before:** Note that data loss may occur in some circumstances if the destructive flag happens to be enabled when running against production.
+**After:** CAUTION: Do not use the `--force` flag against production. The flag deletes rows that do not match the source.
+
+### Section 8 — Punctuation and word count (Rules 8.1-8.7)
+
+| Rule | Instruction |
+|---|---|
+| 8.1 | All standard punctuation is legal except the semicolon. Write two sentences instead. |
+| 8.2 | Use hyphens to connect words that act as one unit. |
+| 8.3 | Parentheses are legal for references, item numbers, abbreviations, plural forms, explanations, alternatives. |
+| 8.4 | In a vertical list, the lead-in colon ends a sentence for word count. |
+| 8.5 | Text inside parentheses counts as one word. |
+| 8.6 | Count as one word each: numbers, numbers with units, abbreviations, alphanumeric identifiers, quoted text, titles, labels, proper nouns. |
+| 8.7 | A hyphenated word counts as one word. |
+
+Rule 8.6 matters for software text: `sqlpipe run --config sqlpipe.yaml` in backticks is quoted text and counts as one word. Long identifiers do not blow your sentence budget.
+
+### Section 9 — Writing practices (Rules 9.1-9.4, GR-1 to GR-8)
+
+| Rule | Instruction |
+|---|---|
+| 9.1 | When a word-for-word replacement does not work, restructure the sentence. |
+| 9.2 | Use each approved word correctly: approved meaning, approved part of speech. |
+| 9.3 | Do not build phrasal verbs ("go down" → "decrease", "set up" → "install" or "configure"). |
+| 9.4 | Keep one consistent style and terminology through the whole document. |
+
+General recommendations GR-1 to GR-8: keep the conjunction "that", be careful with "with", give pronouns clear referents, prefer "this + noun" over bare "this", avoid false friends, avoid Latin abbreviations, use inclusive language, and use the possessive apostrophe form only when you are sure it is correct (GR-8: if unsure, do not use it — non-native readers find it hard).
+
+GR-6 for software docs: "e.g." → "for example", "i.e." → "that is", and delete "etc." — name the items or write "and more".
+
+## VOCABULARY DISCIPLINE
+
+The official dictionary (~900 approved words, ~1,200 banned words with alternatives) is copyrighted by ASD and is not reproduced here. Its mechanics apply without it: **one word, one meaning, one part of speech.**
+
+Known part-of-speech rulings, useful as patterns:
+
+| Word | Ruling |
+|---|---|
+| test, check, work | Noun only. "Do a test", not "test the pump". "Check that X" becomes "make sure that X". |
+| oil | Technical noun (TN) only. For the verb, the dictionary gives "lubricate": "Lubricate the linkage with oil." |
+| help | Verb only. For the noun, the dictionary gives "aid": "with the aid of". |
+| fall (noun) | Rejected. Use "decrease" for a reduction in value. Use FALL (verb) only for physical movement downward by gravity: "Make sure that the tools do not fall into the engine." |
+| follow | "To come after" only, never "obey". Write "obey the instructions". |
+| above, below | Physical positions only. For limits write "more than", "less than". |
+
+### The modal ladder
+
+| You wrote | STE writes |
+|---|---|
+| should (requirement) | must |
+| should (recommendation) | Delete it, or state it as fact: "X is better because Y." |
+| may / might / could (possibility) | can |
+| may (permission) | can |
+| would (hypothetical) | Restructure: "If X occurs, Y occurs." |
+
+### Slop-to-simple substitutions
+
+This table is ours, not the ASD dictionary. It maps the words AI-generated docs overuse to plain replacements. If the word carries no fact, delete it instead of replacing it.
+
+| Slop | Write instead |
+|---|---|
+| leverage, utilize | use |
+| in order to | to |
+| prior to | before |
+| ensure | make sure that (strict mode; in pragmatic mode, ensure is an allowed pick if it is your one chosen check-verb) |
+| it is worth noting that | (delete) |
+| it's important to, crucially | (delete — state the fact) |
+| simply, just, easily, seamlessly, effortlessly | (delete) |
+| robust, powerful, comprehensive, performant | (delete, or give the measurable property) |
+| functionality | function, feature |
+| enables you to, allows you to | you can |
+| is designed to, aims to | (delete — say what it does) |
+| facilitate | help, make possible |
+| dive into, delve into | read, examine |
+| when it comes to | for |
+| in the event that | if |
+| due to the fact that | because |
+| as needed, as necessary | (state the condition) |
+| and/or | Pick one, or write "X, or Y, or both" |
+| e.g. / i.e. / etc. | for example / that is / (name the items) |
+| gracefully handles | (say what it does: "retries three times, then stops") |
+| out of the box | by default |
+| under the hood | internally |
+| blazingly fast, state-of-the-art | fast (give the number) / (delete) |
+| streamline | make simpler, make faster |
+| plethora, myriad | many |
+| addresses the issue, tackles | corrects the fault, removes the error |
+
+### Consistency pass
+
+Collapse synonym rotations to one term each (Rules 1.11, 9.4). The two lists below work differently.
+
+**Technical nouns — not in the dictionary. Pick one and keep it consistent (both modes):**
+
+- config / configuration / settings / options → pick one
+
+**Dictionary rulings — the standard has already chosen. Use the approved word (strict mode); pick one and keep it consistent (pragmatic mode):**
+
+| You wrote | Dictionary status | Use instead |
+|---|---|---|
+| check (verb) / verify / confirm / ensure | All rejected as verbs | `make sure that` (strict); pick one (pragmatic) |
+| validate | Not in dictionary | Use as technical verb (Rule 1.12), or replace with `make sure that` |
+| delete / drop (verb) / destroy | All rejected | `erase` (data), `remove` (physical); avoid `drop` and `destroy` |
+| remove | Approved verb | Keep it |
+| run / execute | Both rejected | `operate` for run, `do` for execute (strict); pick one (pragmatic) |
+| invoke / launch | Not in dictionary | Use as technical verbs (Rule 1.12) |
+| display (verb) / render / present (verb) | All rejected | `show` (approved verb) |
+| issue | Not in dictionary | Use as technical noun, or replace with `problem` (approved) |
+| failure | Rejected in general use; approved as TN for performance loss | Use only when it means a performance error: "a failure of the pump" |
+| error | Approved noun | Keep it |
+| problem | Approved noun | Keep it |
+
+## Untouchables
+
+These are technical names (Rules 1.5, 8.6). Leave them exact, even when they break vocabulary rules:
+
+- Code blocks, inline code, identifiers, CLI commands, flags, file paths
+- Quoted error messages and log lines
+- Product names, API endpoint names, config keys
+- Numbers with units — each counts as one word in the sentence limit
+
+## Beyond Documentation
+
+Same rules, different targets. Full adaptations in `references/use-cases.md`:
+
+- **Error messages**: state what happened (simple past), the cause if known, then the fix as an imperative. No "Oops", no "Please ensure", no apology filler.
+- **Runbooks**: STE's home turf. Imperative steps, conditions first, warnings before the step.
+- **Incident reports**: simple past only. "We have identified an issue that may have impacted" becomes "Between 14:02 and 14:31 UTC, 12% of requests failed."
+- **Release notes**: breaking changes follow the warning pattern — command first, risk second.
+- **Agent instructions (prompts, AGENTS.md)**: a system prompt is a procedure for a reader that cannot ask questions. One instruction per sentence, no "should", condition first.
+- **Translation prep**: STE's original job. One meaning per word plus complete grammar removes most translation ambiguity.
+
+## Self-Check Before You Deliver
+
+This step is not optional. Run these four checks on your draft:
+
+1. Count words in your three longest sentences. Over the 20/25 limit → split them.
+2. Search your draft for: `'ll`, `'re`, `'s` (contraction), `has been`, `have been`, `should`, `-ing` verbs after a comma, semicolons.
+3. Search for every `if` and `when`. Each one stands at the START of its sentence, before the command. "Increase the timeout if the network is slow" → "If the network is slow, increase the timeout."
+4. Search for the verbs you did NOT pick in Your Task step 3 (the check/verify/confirm set). Replace every hit with your chosen verb.
+
+Fix what you find, then deliver. For a full audit, run `references/checklist.md`.
+
+## Full Example
+
+**Before (real unedited AI output):**
+
+> **Connection timeouts.** If sqlpipe hangs or fails with `dial tcp: i/o timeout`, check that the host running sqlpipe can reach the Postgres port (usually 5432) — this is often a security group or firewall rule blocking the connection. If you're connecting to a managed database (RDS, Cloud SQL, etc.), confirm the instance allows connections from sqlpipe's IP. You can also try increasing `source.connect_timeout_seconds` in your config, since a slow network path can trip the default timeout even when the connection eventually succeeds.
+
+**After (classified procedural, verb = "make sure", conditions first, one instruction per sentence):**
+
+> **Connection timeouts.** sqlpipe stops with `dial tcp: i/o timeout` when it cannot reach the Postgres port (5432 by default).
+>
+> 1. Make sure that the host that runs sqlpipe can reach the Postgres port. A firewall or security group usually blocks it.
+> 2. If the database is managed (RDS, Cloud SQL), make sure that the instance accepts connections from the IP of sqlpipe.
+> 3. If the network is slow, increase `source.connect_timeout_seconds` in the configuration.
+
+What changed: 40-word sentences split under 20; "you're" expanded; "check/confirm" collapsed to "make sure that"; every condition moved before its command; "etc." removed; code and error strings untouched.
+
+## Limits
+
+STE is for technical facts and instructions. Do not apply it to marketing copy, blog voice, or brand writing — it deletes persuasion by design. When a user asks for STE on marketing text, say so and offer it for the docs instead.

+# Verification checklist
+
+Run this pass on every draft before you deliver it. The checks are ordered from mechanical to judgment.
+
+## Mechanical checks (searchable)
+
+Search the draft for each pattern. Every hit outside code blocks and quoted text is a violation.
+
+| Search for | Violation | Fix |
+|---|---|---|
+| `'ll`, `'re`, `'ve`, `n't`, `it's` | Contraction (Rule 4.2) | Expand it. |
+| `has been`, `have been`, `had been` | Present/past perfect (Rule 3.4) | Simple past or simple present. |
+| `has` / `have` + past participle | Present perfect (Rule 3.4) | Simple past. |
+| `should`, `would`, `may`, `might`, `could` | Unapproved modal (Rule 3.2) | See the modal ladder in SKILL.md. |
+| `is being`, `are being`, `was being` | Progressive passive (Rules 3.4, 3.5) | Active, simple tense. |
+| `, making`, `, allowing`, `, enabling`, `, ensuring` | "-ing" clause as verb (Rule 3.5) | New sentence with a real subject. |
+| `;` | Semicolon (Rule 8.1) | Two sentences. |
+| `e.g.`, `i.e.`, `etc.` | Latin abbreviation (GR-6) | "for example", "that is", name the items. |
+| `simply`, `easily`, `seamlessly`, `robust` | Filler (no fact) | Delete. |
+| ` if `, ` when ` (mid-sentence) | Trailing condition (Rule 5.4) | Move the condition to the start of the sentence, add a comma. |
+
+## Countable checks
+
+1. **Sentence length.** Count words in each sentence. Procedural limit: 20. Descriptive limit: 25. Notes: 25.
+   Backticked commands, numbers with units, and identifiers count as one word each (Rule 8.6).
+2. **Paragraph size.** Maximum six sentences per paragraph (Rule 6.6).
+3. **Multi-word nouns.** Any noun chain over three words → break it with prepositions (Rule 2.1).
+4. **Instructions per sentence.** One, unless the actions are simultaneous (Rule 5.2).
+
+## Judgment checks
+
+5. **Classification.** Is each passage cleanly procedural or descriptive? Procedures in imperative, descriptions never in imperative.
+6. **Voice.** Any passive sentence: is the agent truly unknown, and is the passage descriptive? Otherwise make it active (Rule 3.6).
+7. **Condition placement.** Every "if/when" stands before its command, with a comma (Rule 5.4).
+8. **Synonym rotation.** One term per concept across the whole document (Rules 1.11, 9.4). Scan for check/verify/confirm, config/settings, run/execute.
+9. **Warnings.** Command or condition first, risk second (Rules 7.2, 7.3).
+10. **Completeness.** Articles present, "that" present after "make sure", no telegraph style (Rule 4.2).
+11. **Untouchables intact.** Code, identifiers, quoted errors, and proper nouns are unchanged.
+
+## When reporting violations (check mode)
+
+For each violation give: the rule number, the offending text, and a compliant rewrite. Cite only rule numbers that appear in SKILL.md.
+End the report with this statement when the user asked for STE compliance: "No tool can guarantee ASD-STE100 compliance. Final approval rests with the writer. The official standard is a free download at asd-ste100.org."

+# Use cases beyond documentation
+
+STE was built for aircraft maintenance manuals. The same properties — one meaning per word, short sentences, condition-first commands — transfer to any text where misreading has a cost. By the end of Issue 8, 64% of registered STE users were outside aerospace and defense.
+
+Each case below names the mode and the adaptations.
+
+## Error messages and CLI output
+
+Mode: procedural. This is the highest-value target: an error message is a 2 a.m. instruction to a stressed reader.
+
+Pattern: state what happened (past simple), state the cause if known, give the command or condition to fix it.
+
+> **Before:** Oops! Something went wrong while attempting to establish a connection. Please ensure your credentials are properly configured and try again.
+> **After:** Connection to the database failed. The password for user `app` was not correct. Set `DB_PASSWORD` and connect again.
+
+## Runbooks and standard operating procedures
+
+Mode: strict-leaning procedural. This is STE's home turf — an on-call runbook is a maintenance manual.
+
+- Every step imperative, one instruction per step, conditions first.
+- Warnings before the step, command first, risk second.
+- 20-word limit enforced hard: an operator under pager stress reads each sentence once.
+
+## Incident reports and postmortems
+
+Mode: descriptive. Simple past only — a timeline in present perfect ("we have identified...") hides when things happened.
+
+> **Before:** We have identified an issue that may have impacted some users' ability to access the service.
+> **After:** Between 14:02 and 14:31 UTC, 12% of requests failed. A deploy at 14:00 removed the cache warmup step.
+
+STE bans hedges ("may have impacted") — the report states what is known and says "unknown" for the rest. This reads more honest because it is.
+
+## Commit messages and PR descriptions
+
+Mode: descriptive body, imperative subject. Convention already matches STE: imperative subject line, plain past facts in the body. Apply the substitution table and the 25-word limit to the body. Delete "this PR aims to".
+
+## API changelogs and release notes
+
+Mode: descriptive. One entry, one change, one sentence where possible. "Breaking:" entries follow the warning pattern — command first: "Update your calls to `v2/users`. The `name` field split into `first_name` and `last_name`."
+
+## Instructions for AI agents (prompts, AGENTS.md, skills)
+
+Mode: procedural. A system prompt is a procedure executed by a reader with no ability to ask questions — the exact reader STE was designed for.
+
+- One instruction per sentence keeps rules independently quotable and hard to half-follow.
+- One word, one meaning prevents the model from treating "check", "verify", and "validate" as three different operations.
+- Condition-first ("If the build fails, stop") beats trailing conditions, which models drop.
+- No "should" — a model reads "should" as optional. Write "must" or delete the rule.
+
+## Support macros and status-page updates
+
+Mode: descriptive, 25-word limit. Non-native readers are the majority of many user bases. No "we sincerely apologize for any inconvenience this may have caused" — "The API was down for 18 minutes. Uploads made during this time were saved and will process today."
+
+## Translation and localization prep
+
+Mode: strict. STE's original purpose was making English readable for non-native maintenance crews, and it doubles as pre-editing for machine translation. One meaning per word plus complete grammar (articles, "that") removes most translation ambiguity. If your docs get localized, STE cuts the error rate and the cost.
+
+## UI copy and empty states
+
+Mode: procedural, hard length limits. Buttons and labels are technical names (exempt). Body copy follows the rules: "No projects yet. Create a project to start." Nothing else survives at this length anyway.
+
+## Where STE does not fit
+
+Marketing pages, launch posts, blog voice, brand writing. STE deletes persuasion on purpose. Write those in your own voice — then use STE for the docs the landing page links to.

+"""Meta Model API (Muse Spark) provider plugin for Hermes Agent.
+
+Provider profile for Meta Superintelligence Labs' Muse Spark family, served
+via the OpenAI-compatible Meta Model API at ``https://api.meta.ai/v1``.
+
+Bundled from https://github.com/albertodepaola/hermes-meta-provider. Hermes'
+provider discovery (``providers/__init__.py``) imports it on first
+``get_provider_profile()`` / ``list_providers()`` call, and the module-level
+``register_provider()`` below wires it into the registry.
+
+Design notes
+------------
+* **Zero core edits.** Everything rides on ``ProviderProfile`` hooks. No changes
+  to hermes' ``model_metadata.py`` / ``models.py`` / ``run_agent.py`` are needed:
+  - Context window (1M), reasoning and vision capabilities already resolve from
+    models.dev for the muse-spark family, so no static ctx table entry is required.
+  - The reasoning dial is emitted as a **top-level ``reasoning_effort``** kwarg
+    (returned in the ``top_level`` slot of ``build_api_kwargs_extras``), which the
+    chat-completions transport merges unconditionally. This deliberately avoids
+    the ``extra_body.reasoning`` path, whose emission is gated by a hardcoded
+    host allowlist in core (``AIAgent._supports_reasoning_extra_body``) that a
+    third-party plugin must not edit.
+* **Meta 400 on ``reasoning_effort: "none"``.** Muse rejects ``none``; disabling
+  reasoning maps to ``"minimal"`` instead.
+* **``default_max_tokens=16384``.** Muse spends completion budget on hidden
+  reasoning tokens first; small caps can finish with empty content.

+### Managed LLM Operation Names
+
+Hermes identifies managed LLM operations by provider wire protocol, not by the
+physical service routing the request. This keeps Relay middleware and codec
+selection stable when providers such as OpenRouter or Nous expose an
+OpenAI-compatible API:
+
+| Hermes API mode | Relay operation |
+| --- | --- |
+| `chat_completions` | `openai.chat_completions` |
+| `codex_responses` | `openai.responses` |
+| `anthropic_messages` | `anthropic.messages` |
+
+Middleware written against earlier Hermes builds might match physical provider
+names such as `openrouter`, `nous`, or `anthropic` as the operation. Match the
+canonical operation instead. Hermes retains the original provider in the
+managed invocation metadata field `hermes.provider`. Unknown or custom API
+modes continue to use the physical provider name as their operation.
+
 ### Dynamic Plugins

+"""Per-plugin persistent storage convention.
+
+Plugins that want durable state today invent their own paths, and most of
+them invent the same wrong one: a scratch directory inside
+``<hermes home>/plugins/<name>/``. That tree is the plugin *install* dir —
+``hermes plugins remove`` deletes it and ``hermes plugins update`` git-pulls
+into it — so user data parked there dies with the code that wrote it.
+
+This module is the sanctioned alternative: one data root per plugin under
+``<hermes home>/plugin-data/<name>/``, owned by the user, untouched by
+install/update/remove. Agent-built plugins get durable state without
+inventing a storage story, and every plugin's data is inspectable in one
+predictable place.
+
+Secrets are deliberately NOT part of this convention — credential reads go
+through ``agent.secret_scope`` / ``.env`` like everywhere else in Hermes.

+# Box
+
+Use Box as the cloud file system for file operations, collaboration, metadata, and document work. Run operations with Hermes' `terminal` tool and use the Box CLI; use the SDK guide when building an application.
+
+## When to Use
+
+- Organizing, uploading, versioning, moving, sharing, or collaborating on Box files and folders
+- Searching Box content or existing metadata
+- Asking questions about Box files, extracting metadata, or generating text grounded in a file
+- Processing a Box folder at scale without downloading every source file
+- Building a Box-backed application, integration, or webhook handler
+
+## Start broad file-system conversations
+
+When someone is exploring a cloud file system for Hermes, first give a short fit assessment: Box is useful when a team needs cloud file storage, sharing, search, metadata, and document work. Then ask whether they want to connect a Box account with OAuth or build a Box-backed application or integration with an SDK.
+
+OAuth makes Hermes act as the Box account authorized in the browser. That account's Box permissions determine what Hermes can access. To give Hermes narrower access, authorize an account that is invited only to the required files, folders, or Hubs.
+
+Do not run setup, show a command cookbook, propose account plans or folder taxonomies, or load every reference for a broad exploratory question. Wait for the user's answer, then load only the relevant path. When a request already names a concrete outcome, skip this discovery step and handle that outcome directly.
+
+Start normal CLI work with the official Box CLI OAuth app. It covers ordinary content work and Box AI. Use a custom **User Authentication (OAuth 2.0)** Platform App only when the requested operation needs an additional OAuth scope, such as webhook management. This remains an OAuth flow; do not substitute a server-side or impersonation identity.
+
+## Perform chosen setup interactively
+
+When a user selects an authentication path or asks Hermes to connect Box, perform the setup through `terminal`; do not turn the next response into instructions for the user to copy. Take the next safe action yourself, and pause only for an approval, browser sign-in, administrator action, or secret that Hermes cannot safely supply.
+
+- If `box` is missing, ask for any terminal approval required to install `@box/cli` under the current Hermes home at `tools/box-cli`; then verify it with the shell-appropriate command in [CLI guide](references/cli-guide.md). Do not attempt a global npm install, use `sudo`, change npm's global prefix, or change `PATH`.
+- Before OAuth, ask: **“Is Hermes running on the same computer as the browser you will use to authorize Box, or on a remote host such as a VPS, container, or cloud VM?”** Use normal `box login` only for the same-computer path. Use `box login --code` only for the remote/headless path. Do not infer runtime topology from the operating system alone; read [OAuth setup](references/oauth-setup.md) after the user answers.
+- Before starting browser authorization, state that Hermes will act as the Box account signed in there. If the user wants narrower access, they can authorize an account that is invited only to the required files, folders, or Hubs. Do not make that account an administrator to unlock an exceptional operation.
+- If a custom OAuth Platform App is necessary, use the CLI's interactive Platform App flow. Ask the user to enter its client secret only in the local CLI prompt; never request it in chat, write it to Hermes configuration, or commit it.
+- If an install, browser authorization, environment switch, or permission change needs approval, request that approval and resume the setup after it is granted. Do not replace the action with a command list.
+
+## Start each task
+
+1. Confirm the CLI and current actor. Probe with `command -v box` on POSIX shells or `Get-Command box -ErrorAction SilentlyContinue` in PowerShell. If `box` is on `PATH`, use it. If Hermes installed the CLI under its current home, use the shell-appropriate verified runner in [CLI guide](references/cli-guide.md) in place of every leading `box`. Then run `box users:get me --json --fields id,name,login` with that runner.
+   If this succeeds, record the actor and continue. Do not ask about authentication again. Treat `folders:items 0` only as a listing of the actor's root; it is not proof that a shared file, folder, or Hub is inaccessible. For a known file or folder, verify its ID directly; for a Hub, use the Hubs discovery path in [Box Hubs](references/hubs.md).
+2. If authentication is absent, ask to connect a Box account with OAuth, then ask whether Hermes and the authorization browser run on the same computer or on separate hosts. Read [OAuth setup](references/oauth-setup.md).
+3. Read the relevant reference before operating. Use documented commands first; only run subcommand help when the request needs an option not covered by the reference or the installed CLI rejects the documented form.
+
+Examples labeled `bash` use POSIX continuation syntax. In PowerShell, run the Box command on one line or replace each trailing `\` with PowerShell's backtick continuation. Do not paste POSIX variable assignments into PowerShell.
+
+## Extend the CLI without pausing
+
+When the Box CLI lacks a dedicated subcommand, use `box request` for the matching REST endpoint and continue the ordinary operation. Do not ask the user to choose merely because the implementation uses REST; it is the same Box task and preserves the configured CLI identity. Read [REST API fallback](references/rest-api.md) when the endpoint needs a request body or custom header.
+
+Ask before a delete, a collaboration/shared-link or permission change, an identity change, a broad or costly batch mutation, or when the target or scope is ambiguous. Otherwise perform the requested operation and verify it.
+
+## Choose the right path
+
+| Need | Read |
+| --- | --- |
+| CLI conventions, environments, JSON, or REST escape hatch | [CLI guide](references/cli-guide.md) |
+| Files, folders, versions, links, or collaborations | [Content workflows](references/content-workflows.md) |
+| Search, metadata, Box AI, or AI units | [Search and AI](references/search-and-ai.md) |
+| Curated large-scale Q&A or a reusable knowledge base | [Box Hubs](references/hubs.md) |
+| Many files or a resumable batch | [Bulk operations](references/bulk-operations.md) |

+| Webhooks or Events API | [Webhooks and events](references/webhooks-and-events.md) |
+| CLI unavailable or a missing CLI operation | [REST API fallback](references/rest-api.md) |
+| Auth, permissions, rate limits, or API errors | [Troubleshooting](references/troubleshooting.md) |
+
+## Content handling policy
+
+For semantic analysis of Box-hosted content, prefer Box AI: it preserves Box permissions, processes source files through Box's governed AI integration, keeps source-file bodies out of Hermes' coding-model context, and scales document work without downloading every file. Do not criticize or block another workflow; use it when the user explicitly chooses it.
+
+Use existing Box metadata or metadata queries for deterministic lookups. Otherwise use Box AI:
+
+- `ai:ask` for Q&A, summaries, and comparisons
+- `ai:extract-structured` for known fields or metadata templates
+- `ai:extract` for flexible key-value extraction
+- `ai:text-gen` for writing grounded in one Box file
+
+For Q&A over more than 25 files or a reusable curated knowledge base, prefer Box AI for Hubs. Discover an existing accessible Hub first; only create or populate one after the user approves the shared-resource change. If no Hub is available and the user does not want one created, narrow a one-off request with search or metadata. Do not use a Hub for metadata extraction or text generation. Read [Box Hubs](references/hubs.md).
+
+When the user asks to extract metadata from a Box file, treat it as a request to persist the result unless they ask for a preview. Use structured extraction with inline fields when the desired schema is known and freeform extraction when the fields are exploratory. Reuse a compatible existing enterprise template when one represents every requested field. Otherwise store flat scalar results in the built-in `global.properties` metadata instance, or upload a JSON sidecar beside the source file when the result contains nested objects, tables, or values that must retain their types. Read every write back and compare it with the intended result. Never silently substitute a file description, attach a partial or unrelated template, truncate fields, or discard fields.
+
+Do not create or change metadata templates. Box does not permit creation of global templates, and enterprise-template administration is outside Hermes' normal OAuth content workflow. If the user needs reusable typed enterprise metadata and no compatible template exists, explain that a Box Admin or authorized Co-Admin must create it separately, leave existing structured metadata unchanged, and report the persisted `global.properties` instance or JSON sidecar instead. Read [Search and AI](references/search-and-ai.md) for the complete extraction and writeback workflow.
+
+Before the first Box AI request, state that Box AI must be enabled, consumes AI units, and remains limited to the current actor's permissions; do not wait for acknowledgement. An AI response returned to Hermes can still contain sensitive information. Confirm only when a material batch's file scope or expected AI-unit use is ambiguous, or when the user has not explicitly requested that scale. See [Search and AI](references/search-and-ai.md).
+
+## Operate safely
+
+- Prefer IDs to paths and verify the current actor before diagnosing a missing file.
+- Use `--json` and `--fields` to keep output small. For mutations, inventory first, confirm ambiguous or large scope, then read back the result.
+- Run ordered CLI mutations serially so progress and recovery are unambiguous. Use documented bulk input support or bounded SDK concurrency for scalable work.
+- Do not create a shared link merely to provide navigation. Shared links change access and require explicit confirmation.
+- Do not put secrets in chat, command output, source control, or logs.
+
+## Report results
+
+For every individually reported Box item, include its ID and a clickable navigation link:
+
+- File: `https://app.box.com/file/<FILE_ID>`
+- Folder: `https://app.box.com/folder/<FOLDER_ID>`
+- Hub: `https://app.box.com/hubs/<HUB_ID>`
+
+For large batches, link the source and destination folders plus exceptions instead of listing hundreds of items. A human may not be able to open content that is only visible to the connected Box account; state that clearly. Include the actor and verification performed in every write summary.
+
+## Verify
+
+After any write, fetch the file or folder with the same actor or list its parent and confirm the returned ID and name. For a metadata write, retrieve the metadata instance and compare every returned field with the intended value; an HTTP success alone is not verification. Report missing, normalized, or rejected values. For a disposable setup check, create a smoke folder, verify it, then delete it only if the user authorized cleanup.

+
+## Workflow
+
+```
+Inventory → classify if needed → plan → confirm → execute → verify → report
+```
+
+## Inventory and plan
+
+```bash
+box folders:items <FOLDER_ID> --json --max-items 1000 --fields id,name,type,parent
+```
+
+Paginate until every item is accounted for. Record IDs, names, types, target folder IDs, and a completed-ID log. Before broad moves, access changes, or AI use, present the scope and ambiguous cases for approval.
+
+## Classify content
+
+Prefer deterministic filename, extension, and existing-metadata rules. For semantic classification, use Box AI rather than downloading file bodies:
+
+```bash
+box ai:ask --items=id=<FILE_ID>,type=file \
+  --prompt "Classify as invoice, receipt, contract, report, or other." --json
+```
+
+For known fields, use `ai:extract-structured`; for variable fields, use `ai:extract`. Sample a small representative set before processing a large batch. Disclose Box AI unit use and obtain confirmation before a material AI batch.
+
+## Execute and recover
+
+```bash
+box folders:create <PARENT_ID> "Category" --json --fields id,name
+box files:move <FILE_ID> <TARGET_FOLDER_ID> --json --fields id,name,parent
+```
+
+Process ordered CLI mutations serially and log each success or failure. On `409`, find and reuse the existing target. On `429`, honor `Retry-After` and retry the same request. Resume from `inventory minus completed IDs`; do not restart blindly.
+
+Use a documented `--bulk-file-path` workflow when the relevant command supports it. Use bounded SDK concurrency only when the application owns retries, idempotency, and rate-limit handling.
+
+## Verify and report
+
+List each destination and the source folder, then compare IDs and counts with the plan. Report links to the source folder, destination folders, and exceptions. Do not dump hundreds of item links unless the user asks for a manifest.

+# Box CLI guide
+
+Run Box commands through Hermes' `terminal` tool. Prefer the documented command in this skill over exploratory help calls. Use help only when a required option is absent here or the installed CLI rejects the syntax.
+
+## Use one command runner
+
+Resolve one command runner before any Box operation:
+
+1. Check whether `box` already resolves in the runtime shell (`command -v box` on macOS/Linux or `Get-Command box` in PowerShell). If it does, use that command as-is, regardless of where Hermes or Box CLI was installed.
+2. If it does not resolve, install and verify an isolated CLI under a writable, persistent Hermes runtime directory. Prefer the current Hermes home at `tools/box-cli`; `HERMES_HOME` is optional, and Hermes uses its platform default when it is unset (`~/.hermes` on macOS/Linux and `%LOCALAPPDATA%\hermes` on Windows).
+3. If that directory is not writable, ask for a writable persistent directory in the runtime. Do not assume Hermes's source checkout, a global npm prefix, or a user home is writable. If a nonstandard existing CLI is not on `PATH`, ask for its executable path instead of scanning the machine.
+
+Only use `npm exec --prefix` after Hermes installed and verified that exact local copy. Run each installation block below as one terminal call, record the verified absolute prefix it prints, and use that literal path in later calls. Never depend on a shell variable surviving a separate Hermes terminal call, and never give the user an unverified `npm exec --prefix` command to run.
+
+Box CLI 4 requires Node.js 18 or newer. Before installing, run `node --version` and `npm --version` in the same runtime and shell Hermes will use. If Node is missing or its major version is below 18, ask for approval to install or activate a supported Node runtime using the environment's normal mechanism, then rerun both checks. If npm is unavailable or the filesystem is not writable, ask for the runtime-appropriate installation or writable Hermes home; do not assume a system package manager, a desktop, or elevated privileges.
+
+On macOS/Linux:
+
+```bash
+node --version
+npm --version
+BOX_CLI_HOME="${HERMES_HOME:-$HOME/.hermes}/tools/box-cli"
+mkdir -p "$BOX_CLI_HOME"
+npm install --prefix "$BOX_CLI_HOME" @box/cli
+npm exec --prefix "$BOX_CLI_HOME" -- box --version
+cd "$BOX_CLI_HOME" && pwd -P
+```
+
+On Windows PowerShell:
+
+```powershell
+node --version
+npm --version
+$boxCliHome = Join-Path $(if ($env:HERMES_HOME) { $env:HERMES_HOME } else { Join-Path $env:LOCALAPPDATA "hermes" }) "tools\box-cli"
+New-Item -ItemType Directory -Force -Path $boxCliHome | Out-Null
+npm install --prefix $boxCliHome @box/cli
+npm exec --prefix $boxCliHome -- box --version
+Resolve-Path $boxCliHome
+```
+
+Keep the resolved runner for the whole task. When Hermes installed the local copy, replace the leading `box` in every example with the applicable `npm exec --prefix` runner below. Otherwise run the examples with the already-resolved `box` command.
+
+The examples in other references use `bash` fences and POSIX `\` continuations. In PowerShell, keep the same Box arguments but run the command on one line or use PowerShell's backtick continuation. Use PowerShell variables only in PowerShell examples.
+
+On macOS/Linux:
+
+```bash
+npm exec --prefix "<VERIFIED_ABSOLUTE_PREFIX>" -- box
+```
+
+On Windows PowerShell:
+
+```powershell
+npm exec --prefix "<VERIFIED_ABSOLUTE_PREFIX>" -- box
+```
+
+For example on macOS/Linux:
+
+```bash
+npm exec --prefix "<VERIFIED_ABSOLUTE_PREFIX>" -- box users:get me --json --fields id,name,login
+```
+
+Do not attempt a global npm install, use `sudo`, change npm's global prefix, or change `PATH`.
+
+## Check identity and control output
+
+On macOS/Linux:
+
+```bash
+command -v box
+box --version
+box users:get me --json --fields id,name,login
+box folders:items 0 --json --max-items 20 --fields id,name,type
+```
+
+On Windows PowerShell:
+
+```powershell
+Get-Command box -ErrorAction SilentlyContinue
+box --version
+box users:get me --json --fields id,name,login
+box folders:items 0 --json --max-items 20 --fields id,name,type
+```
+
+Use `--json` for machine-readable output and `--fields` to return only needed fields. Folder `0` is the current actor's root, not a complete access inventory: do not use its listing to reject a shared file or folder, and never use it to discover Box Hubs.
+
+## Environments and actors
+
+```bash
+box configure:environments:list
+box configure:environments:set-current <ENVIRONMENT_NAME>
+box users:get me --json --fields id,name,login
+```
+
+The CLI has one current environment. Confirm before switching it, then verify the actor. Perform ordinary Hermes work as the OAuth identity selected for that environment; do not impersonate another user.
+
+An isolated npm installation isolates the CLI executable, not its authenticated environments. Box CLI stores environments and tokens for the runtime's OS user, using the platform credential store when available and `~/.box` as a fallback. Hermes profiles and concurrent sessions running as the same OS user can therefore share the current Box environment. Warn about this shared state during setup, verify the actor before every task, and explain that changing the current environment can affect other Hermes sessions and ordinary Box CLI use under that OS account.
+
+On Linux, Box CLI secure storage depends on Secret Service/libsecret support. If the CLI reports a plaintext fallback, warn that credentials may be stored in `~/.box/box_environments.json` and token-cache files. Do not read or print those files. Recommend configuring the runtime's supported Secret Service/libsecret package or using a properly isolated runtime user before production use; do not assume a package manager or require another confirmation merely to deliver the warning.
+
+## Pagination and search
+
+```bash
+box folders:items <FOLDER_ID> --json --max-items 100 --fields id,name,type
+box search "quarterly review" --json --limit 20 --fields id,name,type,parent
+box metadata-query enterprise_12345.contractTemplate <ANCESTOR_FOLDER_ID> \
+  --query "status = :status" --query-param status=active --json
+```
+
+Paginate inventories fully before bulk work. Metadata queries require the template scope/key and an ancestor folder ID.
+
+## REST escape hatch
+
+When the CLI has no dedicated command, preserve its configured auth with `box request` and perform the ordinary requested operation. Do not stop to ask simply because this uses REST; read [REST API fallback](rest-api.md) for endpoint-specific bodies and headers.
+
+```bash
+box request /files/<FILE_ID> --json
+box request /files/<FILE_ID> -X PUT --body '{"name":"renamed.pdf"}' --json
+box request /folders -X POST --body '{"name":"New folder","parent":{"id":"0"}}' --json
+```
+
+Use `box request` as the CLI-based REST fallback. Use an SDK or raw HTTP only when the CLI is unavailable or application code genuinely needs direct REST.
+
+## Batch inputs and mutations
+
+Many Box CLI commands accept `--bulk-file-path` for CSV or JSON input. Use it only after inventorying the target set and confirming material writes. For ordered moves, version updates, and other recoverable mutations, keep an operation log and process serially. Use bounded concurrency in application SDK code only when its retry and rate-limit behavior is explicit.
+
+## Confirmation rules
+
+- Confirm before deletes, access changes, identity changes, broad moves, or an ambiguous target.
+- Confirm the scope before an AI-unit-consuming bulk request.
+- Do not pass `--yes` unless the user has already approved the exact operation.

+# Content workflows
+
+Use IDs, not paths, once an item is resolved. If the current OAuth identity cannot see the target, verify the exact item ID and ask the owner to invite that identity to the intended file, folder, or Hub.
+
+## Browse and create folders
+
+```bash
+box folders:get <FOLDER_ID> --json --fields id,name,parent,item_collection
+box folders:items <FOLDER_ID> --json --max-items 100 --fields id,name,type
+box folders:create <PARENT_ID> "Customer-123" --json --fields id,name,parent
+```
+
+Duplicate names in one parent return `409`. Reuse the existing folder ID instead of retrying blindly.
+
+## Verify a shared file or folder
+
+When the current OAuth identity receives a file or folder invite, use the ID from its Box URL if available and fetch that exact item. Do not use an absence from folder `0` as proof that access failed; it is only that identity's root listing. If only a name is known, use Box search to resolve the ID, then fetch the item:
+
+```bash
+box search "Quarterly plan" --json --limit 20 --fields id,name,type,parent
+box files:get <FILE_ID> --json --fields id,name,parent
+box folders:get <FOLDER_ID> --json --fields id,name,parent
+```
+
+Use [Box Hubs](hubs.md) for a Hub invite: Hubs are not files or folders and are discovered separately.
+
+## Upload, download, and version files
+
+```bash
+box files:upload ./artifact.pdf --parent-id <FOLDER_ID> --json --fields id,name,size
+box files:get <FILE_ID> --json --fields id,name,size,sha1,parent
+box files:download <FILE_ID> --destination . --save-as local-copy.pdf
+box files:versions:upload <FILE_ID> ./updated.pdf --json --fields id,name,sha1
+box files:versions:list <FILE_ID> --json
+box files:versions:download <FILE_ID> <VERSION_ID> --destination . --save-as older.pdf
+```
+
+Download source bytes only when the task truly requires local editing or the user explicitly approves external analysis. Prefer a new version over replacing an unrelated file by name.
+
+## Create native Box Notes
+
+When the user asks for a Box Note, create a native note from Markdown through `box request`; do not substitute an uploaded text file named `.boxnote`. Read [REST API fallback](rest-api.md) for the exact request and verification command. Create it immediately when the destination is explicit or unambiguously the actor's root; otherwise ask which folder to use.
+
+## Rename, tag, and move
+
+```bash
+box files:update <FILE_ID> --name "Renamed.pdf" --json --fields id,name
+box files:update <FILE_ID> --description "Updated by Hermes" --tags "reviewed,2026" --json
+box files:move <FILE_ID> <NEW_PARENT_ID> --json --fields id,name,parent
+box folders:move <FOLDER_ID> <NEW_PARENT_ID> --json --fields id,name,parent
+```
+
+Read back the item or its parent after every write. Moving a folder moves its contents; confirm broad moves before executing them.
+
+## File descriptions
+
+Treat 255 characters as the safe file-description limit; Box can truncate longer values. Never use a description as a fallback for extracted metadata. Set one only when the user explicitly asks for a description, verify that the complete intended text fits before writing, then fetch the file and compare the returned description with the intended value. Use [Search and AI](search-and-ai.md) to persist extracted results as metadata or a JSON sidecar instead.
+
+## Collaborate and share
+
+```bash
+box collaborations:create <FOLDER_ID> folder --role editor --login collaborator@example.com --json
+box shared-links:create <FILE_ID> file --access company --json
+box shared-links:create <FOLDER_ID> folder --access open --json
+```
+
+Use the narrowest collaboration role. Creating or widening a shared link changes access, so require explicit confirmation.
+
+## Navigate without changing permissions
+
+Report these links for items already known to the caller; they do not create a shared link:
+
+- File: `https://app.box.com/file/<FILE_ID>`
+- Folder: `https://app.box.com/folder/<FOLDER_ID>`
+
+Include the item ID with the link. If a human cannot open an item visible only to the connected Box account, state that rather than creating a link with broader access.
+
+## Read and write metadata
+
+```bash
+box files:metadata:get <FILE_ID> --scope global --template-key properties --json
+box files:metadata:create <FILE_ID> --scope global --template-key properties \
+  --data invoice_id=INV-001 --json
+```
+
+`global.properties` is Box's built-in schema-free metadata instance; no template creation is required. Its values are not a reusable typed enterprise schema and cannot be used by the Metadata Query API. Read all existing metadata instances before writing so unrelated properties are preserved. Use [Search and AI](search-and-ai.md) when metadata must be extracted from document content; do not use a partial, unrelated, or incomplete enterprise template.

+# Box Hubs
+
+Use a Box Hub for recurring Q&A over a curated knowledge base. A direct Box AI Ask request handles up to 25 selected files; a Hub request sends one `hubs` item and searches the Hub's indexed content. Do not use a Hub for metadata extraction or text generation.
+
+## Check availability and discover an existing Hub
+
+The Box Free Developer Plan includes the Hubs API, Box AI APIs, and a monthly AI-unit allowance for building and testing. Do not apply Box web-app plan wording as a blanket API restriction. The CLI calls the same APIs and does not bypass account entitlements: production availability still depends on the organization's plan and Box configuration.
+
+Before the first Hub AI request, explain that Box AI must be enabled and consumes AI units; do not wait for acknowledgement. Explain that answers only use indexed files the current actor can access. Hubs are not files or folders: never use `folders:items 0` to discover or reject a Hub invitation. Confirm the current actor, then list accessible Hubs before proposing a new one:
+
+```bash
+box users:get me --json --fields id,name,login
+box hubs --scope all --max-items 1000 --json
+box hubs --query "Product" --scope all --sort relevance --json
+box hubs:get <HUB_ID> --json
+box hubs:items <HUB_ID> --max-items 100 --json
+```
+
+For a known Hub URL or ID, run `box hubs:get <HUB_ID>` directly even if the list is empty. Report each Hub as `https://app.box.com/hubs/<HUB_ID>`. Check `is_ai_enabled` before asking a question, then make one bounded Hub Ask request to verify actual API availability. Box AI for Hubs must have been enabled before the Hub was created so Box can index its content. If Hub AI is unavailable, distinguish a disabled feature, a Hub created before AI enablement, indexing delay, missing Hub collaboration, missing access to underlying files, and exhausted AI units; do not silently download source files into Hermes' model context.
+
+## Ask questions across a Hub
+
+Use one Hub item and `single_item_qa`. Request citations so Hermes can report the source files behind an answer. Use `box request` (or the SDK) for Hub Q&A rather than relying on `box ai:ask`, whose installed CLI versions may not accept Hub item types. This uses the Box AI Ask endpoint; the `box-version: 2025.0` header is required for `/hubs` management endpoints, not this request.
+
+```bash
+box request /ai/ask -X POST \
+  --body '{"mode":"single_item_qa","items":[{"id":"<HUB_ID>","type":"hubs"}],"prompt":"Summarize the approved renewal terms and cite each source.","include_citations":true}' \
+  --json
+```
+
+State the Hub ID and navigation link with the answer. List cited file IDs, names, and file links when Box returns citations. Treat an answer as bounded by indexed, accessible Hub content; do not claim it searched files that have not indexed or that the actor cannot access.
+
+## Create and populate a Hub
+
+Do not create a Hub automatically. For Q&A over more than 25 files or a reusable curated collection, discover an existing accessible Hub first. If none fits, offer to create a curated Hub and obtain explicit approval before creating or populating it. If the user declines, narrow the one-off scope with search or metadata instead.
+
+After approval, create it, report its link, and verify it:
+
+```bash
+box hubs:create "Policy knowledge base" --description "Approved policy reference" --json
+box hubs:get <HUB_ID> --json
+```
+
+Adding an item curates a reference; it does not move the underlying file or folder. A clearly requested small addition may proceed without a redundant prompt. Confirm before bulk additions or removals, then verify every returned result and read back the Hub items. The API can return partial success for multi-item changes, so do not treat a successful request alone as proof that every item was added.
+
+```bash
+box hubs:items:manage <HUB_ID> \
+  --add id=<FILE_ID>,type=file --json
+box hubs:items:manage <HUB_ID> \
+  --add id=<FOLDER_ID>,type=folder --json
+box hubs:items <HUB_ID> --max-items 100 --json
+```
+
+Without `parent-id`, the CLI adds the item to the first Item List block. To target a specific Item List block, first list pages with `box hubs:document:pages <HUB_ID> --json`, retrieve blocks with `box hubs:document:blocks <HUB_ID> <PAGE_ID> --json`, then pass the returned Item List block ID as `parent-id`.
+
+Confirm before enabling or disabling Hub AI, deleting or copying a Hub, or changing shared access. Verify each change with `box hubs:get`, `box hubs:items`, or `box hubs:collaborations`:
+
+```bash
+box hubs:update <HUB_ID> --ai-enabled --json
+box hubs:collaborations <HUB_ID> --max-items 100 --json
+box hubs:collaborations:create <HUB_ID> --role viewer --user-id <USER_ID> --json
+```
+
+## Handle indexing, permissions, and limits
+
+Newly added content usually indexes within minutes but can take up to an hour. Verify the item addition, wait or retry a bounded number of times, and report a retryable indexing state instead of declaring the source absent. Diagnose permissions separately: a successful `box hubs` or `box hubs:get` proves Hub access, not access to every underlying file. Hub answers respect the querying actor's access to underlying files.
+
+Box AI for Hubs has a service limit per Hub and across the enterprise. Box's dedicated Hubs guidance currently documents 20,000 files per Hub; verify current account or product documentation when operating near the boundary. Do not present that number as an immutable guarantee. Only the first 4 MB of a supported document's text representation is indexed. Explain AI-unit use before the first request and confirm a material batch or broad Hub population.

+# OAuth setup
+
+Use OAuth for every Hermes-to-Box connection. OAuth follows the signed-in Box user's permissions and the app's scopes; it does not grant enterprise-wide access.
+
+## Choose the OAuth account
+
+Authorize the Box account that Hermes should act as. OAuth follows that account's permissions. If the user wants a narrower permission boundary, authorize an account that is invited only to the files, folders, or Hubs Hermes should access. Do not make that account an administrator merely to unlock an exceptional operation.
+
+Everyone who uses a shared or background Hermes deployment receives the access of the one Box account it authorizes, so do not connect it to a broader personal or administrator account. Before starting the browser flow, make sure the authorization browser is signed in as the intended Box account.
+
+Choose a descriptive environment name, such as `hermes-box-oauth`. Do not overwrite or reauthorize an existing environment until its identity is confirmed.
+
+## Same-host interactive path
+
+First resolve the Box command runner using [CLI guide](cli-guide.md). Then ask whether Hermes runs on the same computer as the browser the user will use to authorize Box. Use this path only when they confirm that it does. This is normally a local computer setup. Do not infer this from the operating system alone. Use the resolved runner; do not reconstruct a local npm prefix unless Hermes installed and verified that exact local copy.
+
+Start one official local login operation without `--code`, leave its terminal process running until it exits, then verify the actor. The examples below use `box`; replace that executable with the previously verified local runner only when Hermes installed and verified a private CLI copy:
+
+```bash
+box login --default-box-app --name <ENVIRONMENT_NAME>
+box users:get me --json --fields id,name,login
+```
+
+The browser flow creates and selects the named environment. Run the action through Hermes's terminal rather than asking the user to copy a runner command. Announce the pending authorization, wait for the CLI process to finish, then continue with the actor check. Let the CLI open the authorization page and receive the local callback. Do not use browser tools, inspect browser tabs, request the resulting URL, navigate to Box, or ask the user to paste a code.
+
+If the callback server cannot bind port 3000, the browser opens an unusable authorization result, or the callback never reaches the waiting CLI, stop that login process before retrying. Retry the official app on the supported ports `3001`, `4000`, `5000`, and `8080`, one at a time, and verify the actor after each successful completion:
+
+```bash
+box login --default-box-app --port 3001 --name <ENVIRONMENT_NAME>
+```
+
+Do not switch a same-host setup to `--code` merely because port 3000 failed. Use `--code` only after the supported local ports fail or the user confirms that the authorization browser is on another host.
+
+## Separate-host or headless path
+
+Use this path only after the user explicitly confirms that Hermes runs on a remote host—such as a VPS, container, or cloud VM—or that it is headless and the authorization browser is on a different computer. Use the same previously resolved runner and run:
+
+```bash
+box login --default-box-app --code --name <ENVIRONMENT_NAME>
+```
+
+Open the displayed URL with a browser tool only when it controls the human's authorization browser. Otherwise present the URL and pause for the user to sign in and approve access, then continue the CLI's code-and-state prompts and verify the actor. Do not use this path when the same-host callback is available.
+
+## Existing environments
+
+The Box CLI stores multiple named environments but uses one current default:
+
+```bash
+box configure:environments:list
+box configure:environments:set-current <ENVIRONMENT_NAME>
+box users:get me --json --fields id,name,login
+```
+
+Request approval before switching the current environment, especially on a shared or background installation. Switch it only after approval and verify the resulting actor. If the returned identity is API-only or has no normal Box login, do not use it for Hermes; connect a normal Box account through OAuth instead.
+
+## Custom OAuth Platform App
+
+Use this path only when the requested operation needs a scope unavailable through the official CLI app, such as **Manage webhooks**. Open the [Box Developer Console](https://app.box.com/developers/console), create or select a Platform App with **User Authentication (OAuth 2.0)**, and enable only the required scopes. Never broaden scopes merely to avoid an authorization error.
+
+Use the same topology decision as the official app. For a same-host browser, add `http://localhost:3000/callback` as an OAuth redirect URI in the app's **Configuration** tab, save it, then run:
+
+```bash
+box login --platform-app --port 3000 --name <ENVIRONMENT_NAME>
+```
+
+If port 3000 cannot bind, choose another free local port, add the exact `http://localhost:<PORT>/callback` URI to the Platform App, save the configuration, stop the failed login process, and retry with the matching `--port`. Unlike the official app, a custom Platform App may use any port whose exact callback URI is registered.
+
+For a remote or headless Hermes runtime whose authorization browser is on a different computer, register the same loopback callback URI and add `--code`:
+
+```bash
+box login --platform-app --code --port 3000 --name <ENVIRONMENT_NAME>
+```
+
+Before starting the remote flow, explain that the browser may finish on an unreachable localhost page; this is expected. The resulting URL contains both `code` and `state`, which the waiting CLI requests. Ask the user for only those two values, submit them to the existing process, and then verify the actor. Do not inspect unrelated browser tabs or switch to the local callback workflow on a remote host.
+
+Let the CLI prompt for the Client ID and Client Secret. Do not ask the user to paste the Client Secret into chat, write it to Hermes configuration, or give the user an unverified local-runner command to copy. Authenticate the intended user in the browser, then verify the resulting actor. Keep administrator-only operations outside the normal Hermes OAuth identity.

+# REST API fallback
+
+Use `box request` to extend the CLI when it has no dedicated subcommand. It reuses the configured Box identity, so continue ordinary requested work without asking the user to choose a REST fallback. Confirm only for deletes, access or identity changes, broad or costly batches, or an ambiguous target or scope. Use direct REST only when the CLI is unavailable or application code needs a raw endpoint that an SDK cannot cover.
+
+Using REST does not bypass Box metadata safety rules: inspect metadata instances and existing schemas first, never create or change a metadata template, and retrieve and compare the metadata instance after every write. Never use a file description as an implicit metadata fallback.
+
+## CLI request escape hatch
+
+```bash
+box request /files/<FILE_ID> --json
+box request /files/<FILE_ID> -X PUT --body '{"name":"renamed.pdf"}' --json
+box request /folders -X POST --body '{"name":"New folder","parent":{"id":"0"}}' --json
+```
+
+## Create a native Box Note
+
+When asked to create a Box Note, create the native note with the Box Notes API; do not upload plain text with a `.boxnote` suffix. Use the intended parent folder (use `0` only when the user's target is unambiguously their root), then fetch the returned file to verify it:
+
+```bash
+box request /notes/convert -X POST \
+  --header "box-version: 2026.0" \
+  --body '{"content":"# Hello world\n\nhello world","content_format":"markdown","parent":{"id":"0"},"name":"hello-world"}' \
+  --json
+box files:get <RETURNED_FILE_ID> --json --fields id,name,type,parent
+```
+
+`content` is Markdown and is limited to 1 MB. Report the returned file ID and its normal Box file link.
+
+## OAuth identity boundary
+
+`box request` uses the selected OAuth CLI environment. It does not bypass that user's Box permissions. If the CLI is unavailable, use an OAuth-authorized SDK client as described in [SDK development](sdk-development.md). Never echo, log, or commit OAuth tokens or client secrets.

+# SDK development
+
+Use this reference for shipped Box applications. For a one-off Hermes task, use the CLI references instead.
+
+## Start with the application
+
+Inspect the repository for existing Box clients, `BOX_` configuration, token storage, webhook handlers, retry policy, and language conventions. Extend the existing integration instead of mixing SDK and raw REST without a reason.
+
+## Choose an identity
+
+| Identity | Use when |
+| --- | --- |
+| OAuth | each end user connects their own Box account |
+
+OAuth follows the signed-in user's permissions and app scopes. For a shared or background application, the Box account that authorizes the application defines its access boundary; invite that account only to the files, folders, or Hubs the application needs.
+
+## Use an official SDK
+
+- [Python SDK Gen](https://github.com/box/box-python-sdk-gen)
+- [The `box` npm package](https://developer.box.com/guides/tooling/box-npm-package)
+- [Existing Node SDK projects](https://github.com/box/box-node-sdk)
+- [Other Box SDKs](https://developer.box.com/guides/tooling/sdks/)
+
+Use the SDK matching the project language. For a new JavaScript or TypeScript application, use the project's existing package manager to install the unified `box` package; with npm, run:
+
+```bash
+npm install box
+```
+
+Import its Node SDK from the explicit SDK subpath:
+
+```typescript
+import BoxSDK from "box/sdk";
+```
+
+The package also exposes a project-local Box CLI through `npx box`. Use that runner for development inside the application when useful, but do not silently replace the separately resolved Hermes CLI runner or its authenticated environment. If the project already uses `box-node-sdk`, extend that integration instead of migrating it without a concrete reason. For Python or another language, install its current official Box SDK rather than the npm package.
+
+Store OAuth tokens and any custom Platform App client secret in the project's approved secret mechanism, not source control. When a custom Platform App needs additional scopes, use **User Authentication (OAuth 2.0)** and have the intended Box user grant access; do not add an impersonation path for normal application work. Keep exceptional enterprise administration outside the normal Hermes runtime and application identity; do not elevate the account the application normally uses.
+
+## OAuth client
+
+Use the generated SDK's OAuth support rather than rebuilding authorization-code exchange or token refresh logic. Follow the installed SDK's current OAuth method names and its language-specific authorization guide when implementing a concrete call. Initialize the OAuth client before calling any SDK method, associate stored tokens with the Box user who granted them, and verify that user before performing work. Do not copy a partial SDK call into an application without its OAuth initialization and token-refresh path.
+
+## Build document-aware apps with Box AI
+
+When an application must understand Box documents, prefer Box AI: it preserves Box permissions, processes source files through Box's governed AI integration, keeps source-file bodies out of the application's external model context, and scales document work without downloading every file:
+
+- ask for Q&A and summaries;
+- structured extract for repeatable fields or a metadata template;
+- extract for variable fields;
+- text generation for output grounded in one Box file.
+
+Before the first request, explain that Box AI must be enabled and consumes AI units. Do not silently switch to external processing when Box AI is unavailable; offer an explicitly chosen alternative neutrally. Treat Box AI responses as potentially confidential application data.
+
+## Build Hub-backed knowledge experiences
+
+For a recurring Q&A experience over a curated collection, use a Box Hub rather than assembling more than 25 file items per Ask request. Discover existing Hubs first; creating a Hub, populating it, enabling its AI features, or changing its collaborations changes shared resources and requires explicit product approval. Box Hubs endpoints use API version `2025.0`.
+
+Use the generated SDK matching the project language. The exact generated method names can vary by SDK release; keep the request shape below and follow the installed SDK's current names.
+
+```python
+from box_sdk_gen import AiItemAsk, AiItemAskTypeField, CreateAiAskMode
+
+answer = client.ai.create_ai_ask(
+    CreateAiAskMode.SINGLE_ITEM_QA,
+    "What changed in the latest policy?",
+    [AiItemAsk(id=hub_id, type=AiItemAskTypeField.HUBS)],
+    include_citations=True,
+)
+```
+
+```typescript
+const answer = await client.ai.createAiAsk({
+  mode: "single_item_qa",
+  prompt: "What changed in the latest policy?",
+  items: [{ id: hubId, type: "hubs" }],
+  includeCitations: true,
+});
+```
+
+Querying a Hub uses its indexed content and only returns information from files the current actor can access. Newly added Hub content can take minutes, and occasionally up to an hour, to index; surface a retryable indexing state rather than treating an early answer as complete. The Free Developer Plan includes the Hubs and Box AI APIs for building and testing, with a monthly AI-unit allowance. Production availability depends on the organization's plan and configuration. In every environment, verify that the Hub exists, has AI enabled, and was created after Hub AI was enabled so its content can be indexed. Read [Box Hubs](hubs.md) for the CLI and operational workflow.
+
+## Webhooks and reliability
+
+Verify webhook signatures, persist idempotency keys, fetch authoritative state after events, and keep retry/backoff policy explicit. Bound concurrent API calls and make retries safe before increasing throughput. See [Webhooks and events](webhooks-and-events.md).

+# Search, metadata, and Box AI
+
+Use Box search and metadata before AI when they answer the request deterministically. For semantic understanding of Box-hosted files, prefer Box AI: it preserves Box permissions, processes source files through Box's governed AI integration, keeps source-file bodies out of Hermes' coding-model context, and scales document work without downloading every file. Do not block or criticize an explicitly chosen alternative workflow.
+
+## Search and metadata queries
+
+```bash
+box search "invoice ACME" --json --limit 25 --fields id,name,type,parent
+box metadata-query enterprise_12345.contractTemplate <ANCESTOR_FOLDER_ID> \
+  --query "status = :status" --query-param status=active --json
+```
+
+Search only returns content visible to the current actor. Resolve IDs and confirm the actor before treating empty results as missing files.
+
+## Select a Box AI operation
+
+| Need | Command |
+| --- | --- |
+| Answer, summarize, or compare 1 file | `ai:ask` with `single_item_qa` |
+| Answer, summarize, or compare 2–25 selected files | `ai:ask` with `multiple_item_qa` |
+| Q&A over more than 25 files | [Box Hubs](hubs.md) |
+| Recurring Q&A over a curated knowledge base | [Box Hubs](hubs.md) |
+| Discover fields from an exploratory prompt | `ai:extract` |
+| Extract a known schema without creating a template | `ai:extract-structured --fields` |
+| Extract against an existing compatible template | `ai:extract-structured --metadata-template` |
+| Write or rewrite text grounded in one file | `ai:text-gen` |
+
+```bash
+box ai:ask --items=id=<FILE_ID>,type=file \
+  --prompt "Summarize the renewal obligations and dates." --json
+
+box ai:extract --items=id=<FILE_ID>,type=file \
+  --prompt "invoice_number, vendor, total, due_date" --json
+
+box ai:extract-structured --items=id=<FILE_ID>,type=file \
+  --fields "key=invoice_number,type=string,description=Invoice number" \
+  --fields "key=total,type=float,description=Invoice total" --json
+
+box ai:text-gen --items=id=<FILE_ID>,type=file \
+  --prompt "Draft a concise customer update based on this file." --json
+```
+
+`ai:text-gen` supports exactly one item. Extraction endpoints return JSON; they do not automatically attach that result to the file. Use structured extraction with inline fields when the desired schema is known, freeform extraction when the fields are exploratory, and `--metadata-template` only when an existing Box template is the source of truth.
+
+Do not use a Hub for metadata extraction or text generation. For semantic Q&A across more than 25 files or a reusable curated collection, read [Box Hubs](hubs.md), discover an existing Hub first, and obtain approval before creating or populating one. If the user does not want a Hub created, narrow the candidate set with search or metadata.
+
+## Diagnose Box AI access
+
+A file that succeeds with `files:get` or search can still fail through Box AI when Box AI is unavailable for the current OAuth identity or account. If the user can preview or download a file but `ai:ask` returns `404 not_found`, do not immediately misdiagnose its collaboration as missing. First verify the current actor and the file permissions:
+
+```bash
+box users:get me --json --fields id,name,login
+box files:get <FILE_ID> --json --fields id,name,permissions
+```
+
+If the file permissions and actor are correct, verify that Box AI is enabled and available for the account or enterprise, that the selected OAuth application has the required AI scope when using a custom Platform App, and that AI units are available. Reauthorize the intended OAuth identity after changing application access, then retry one file before a batch. Do not use impersonation as a fallback; if the wrong identity is selected, switch only with approval to the intended OAuth environment and verify it first.
+
+## Extract and persist file metadata
+
+Treat extraction and persistence as separate operations. Unless the user asks for a preview, the extraction request authorizes writing the result back to Box; do not stop for a redundant confirmation.
+
+### Inspect schemas before extracting
+
+1. Retrieve the file, its parent, and every metadata instance already attached to it.
+   ```bash
+   box files:get <FILE_ID> --json --fields id,name,parent
+   box files:metadata <FILE_ID> --json
+   ```
+2. List the enterprise templates visible to the current OAuth identity and retrieve plausible schemas.
+   ```bash
+   box metadata-templates --json --fields templateKey,displayName,scope
+   box metadata-templates:get <TEMPLATE_KEY> --scope enterprise --json
+   ```
+3. Compare every requested field with each candidate's meaning, field key, and type. Use an existing template only when one semantically appropriate template supports **all** requested fields. Do not attach a partial or unrelated template merely to fit some values.
+
+### Use a compatible existing template
+
+Extract against the template, then add its metadata instance or update the existing instance. Do not write absent, null, incompatible, or truncated values.
+
+```bash
+box ai:extract-structured --items=id=<FILE_ID>,type=file \
+  --metadata-template="type=metadata_template,scope=enterprise,template_key=<TEMPLATE_KEY>" \
+  --json
+
+box files:metadata:create <FILE_ID> --scope enterprise --template-key <TEMPLATE_KEY> \
+  --data "invoice_number=INV-001" --data "total=#1250.00" --json
+
+box files:metadata:update <FILE_ID> --scope enterprise --template-key <TEMPLATE_KEY> \
+  --replace "invoice_number=INV-001" --replace "total=#1250.00" --json
+
+box files:metadata:get <FILE_ID> --scope enterprise --template-key <TEMPLATE_KEY> --json
+```
+
+Use the CLI's required `#` prefix for float values when creating or adding typed metadata. Use full ISO timestamps for Box date fields, such as `2025-03-29T00:00:00Z`. Compare every returned field with the intended typed value. Report the template key, metadata instance `$id`, file ID, and file link.
+
+### Work without a compatible template
+
+Do not create a metadata template. Box does not allow creation in the `global` scope. Enterprise templates can only be created by a Box Admin or a Co-Admin granted template-management permission, and custom templates may depend on the account plan. Template administration is outside Hermes' normal OAuth content workflow.
+
+Choose extraction based on the request, not on template availability:
+
+- For known fields, run `ai:extract-structured` with inline `--fields`; this preserves a predictable typed JSON result without creating a template.
+- For exploratory or variable fields, run `ai:extract` with a precise prompt.
+
+Persist a flat scalar result in Box's built-in `global.properties` instance. It accepts schema-free properties without creating a template. Convert each value to a lossless string representation, validate keys before writing, and preserve unrelated existing properties. If the instance does not exist, create it. If it exists, use `--replace` for existing keys and `--add` for new keys.
+
+```bash
+box files:metadata:get <FILE_ID> --scope global --template-key properties --json
+
+box files:metadata:create <FILE_ID> --scope global --template-key properties \
+  --data "invoice_number=INV-001" --data "total=1250.00" --json
+
+box files:metadata:update <FILE_ID> --scope global --template-key properties \
+  --replace "invoice_number=INV-001" --add "total=1250.00" --json
+
+box files:metadata:get <FILE_ID> --scope global --template-key properties --json
+```
+
+`global.properties` is untyped and cannot be queried with the Metadata Query API. For nested objects, tables, arrays, or any result whose JSON types must remain intact, write the complete extraction response to a UTF-8 JSON sidecar named `<SOURCE_NAME>.<FILE_ID>.metadata.json` and upload it to the source file's parent folder. If that exact sidecar already exists for the workflow, upload a new version rather than creating a duplicate. Fetch the uploaded file and compare its content or checksum with the local JSON, then report both the source and sidecar IDs and links.
+
+If the user explicitly requires reusable typed enterprise metadata, explain that an administrator must create a compatible enterprise template separately. Do not elevate the connected account or switch to an administrator identity. Preserve the extraction through `global.properties` or a JSON sidecar in the meantime, and never silently truncate or discard fields.
+
+### File descriptions are not metadata fallback
+
+**Hard rule:** Never use a file description as an automatic substitute for extracted metadata. Treat 255 characters as the safe limit because Box can truncate longer descriptions. Use `box files:update --description` only when the user explicitly requests a description, first verify the complete intended text fits, then read it back and compare it with the intended value.
+
+## Confidentiality and AI units
+
+Box AI processes source files through Box's governed AI integration instead of downloading source bodies into Hermes' coding-model context. Box AI responses returned to Hermes can still contain confidential information. Do not claim that no third-party model provider is involved or that content can never be used for training; follow Box's current trust and plan documentation.
+
+Before the first Box AI request, explain that Box AI must be enabled, calls consume AI units, and answers remain constrained by the current actor's permissions. For a material batch, state the file count and ask for confirmation. Do not promise a unit balance or per-call cost unless Box exposes it for the current account.
+
+If Box AI is unavailable or out of units, offer existing metadata/search, a smaller sample, enabling units, or explicit approval for local/external analysis. Never silently fall back to downloading files for an external model.
+
+## Scale
+
+Use `--bulk-file-path` where the command supports it. For hundreds of files, inventory first, sample the schema, confirm unit-consuming scope, and use [Bulk operations](bulk-operations.md). For recurring, high-throughput extraction, evaluate Box Extract rather than simulating a folder-wide workflow through repeated downloads.

+# Troubleshooting
+
+Capture the actor, object ID and type, exact command, status code, and safe error body before changing approach.
+
+## First checks
+
+```bash
+box users:get me --json --fields id,name,login
+box configure:environments:list
+box files:get <FILE_ID> --json --fields id,name,parent
+box folders:get <FOLDER_ID> --json --fields id,name,parent
+box hubs --scope all --max-items 1000 --json
+box hubs:get <HUB_ID> --json
+```
+
+Confirm the current actor, resource type, ID, resource-specific collaboration, app scopes, and selected environment. Do not use folder `0` as an access test: it cannot discover a Hub and may not list every shared file or folder.
+
+## Common failures
+
+| Signal | Likely cause | Next action |
+| --- | --- | --- |
+| local OAuth reports `EADDRINUSE`, opens an unusable result, or never returns to the CLI | occupied or mismatched loopback callback port | stop the waiting login process; for the official app, retry `3001`, `4000`, `5000`, then `8080`; for a custom app, register the exact new callback URI before retrying |
+| remote OAuth browser ends on an unreachable localhost page | expected `--code` redirect or wrong topology | if Hermes is remote, return the URL's `code` and `state` to the waiting CLI; if Hermes and the browser are on the same host, stop and restart without `--code` |
+| 401 or 403 | expired auth, missing scope, insufficient role | verify identity, reauthorize the app, and check folder role |
+| shared file/folder absent from root or 404 | wrong actor, an access-only/shared item, or missing file/folder collaboration | verify `users:get me`, then fetch the known file/folder ID directly; only change collaboration after confirming the target and actor |
+| Hub absent from root or 404 | root listing cannot discover Hubs, wrong actor, or missing Hub collaboration | run `box hubs --scope all` and `box hubs:get <HUB_ID>`; verify Hub collaboration separately from underlying-file access |
+| 409 | duplicate name, existing collaboration, metadata conflict | list the parent/template and reuse or rename deliberately |
+| 429 | rate limit | honor `Retry-After`, retry the same request, and reduce batch rate |
+| Box AI access error | feature disabled, plan/unit restriction, unsupported content | explain the limitation and offer metadata/search, a sample, units, or approved fallback |
+
+If two Hermes profiles or sessions appear to change each other's Box actor, remember that a private npm installation does not isolate Box CLI environments for the same OS user. List environments, verify the current actor, and ask before switching. On Linux, if the CLI reports plaintext credential fallback, warn about `~/.box` without reading or printing its credential files and recommend configuring Secret Service/libsecret or an isolated runtime user.
+
+Do not diagnose missing content until identity and access are verified. Do not silently change actors, broaden sharing, or download confidential source files as a workaround.

+# Webhooks and events
+
+Use webhooks for push notifications about a file or folder. Use Events API polling for catch-up, backfill, or a durable cursor. Webhook management requires a custom OAuth Platform App with the **Manage webhooks** scope; the official Box CLI OAuth app is not sufficient. Use the normal OAuth identity that owns or can access the target, not an administrator identity unless the target operation itself requires it.
+
+## Create and inspect a webhook
+
+```bash
+box webhooks:list --json
+box webhooks:create folder <FOLDER_ID> \
+  --triggers FILE.UPLOADED,FILE.VERSION_UPLOADED \
+  --address https://example.com/box/webhook --json
+```
+
+The current actor needs access to the target and the app needs appropriate scopes. Confirm the destination URL and event triggers before creating a webhook.
+
+## Poll user events with a durable cursor
+
+For user catch-up and backfill, use the User Events API through the selected OAuth identity. Do not use the CLI's default `box events` command: it defaults to enterprise admin-log streams. Persist the returned `next_stream_position` after every successful response, then use it on the next poll:
+
+```bash
+box request /events --query "stream_type=changes&stream_position=now" --json
+box request /events --query "stream_type=changes&stream_position=<SAVED_CURSOR>" --json
+```
+
+Use `stream_position=now` only to initialize a future-events cursor. For backfill, begin with an approved historical cursor or reconcile the target folder first, then persist each returned cursor atomically with the processed event IDs.
+
+## Application handler contract
+
+When implementing a shipped application:
+
+1. Verify the Box signature before parsing or acting on the body.
+2. Persist idempotency keys because deliveries can repeat.
+3. Acknowledge quickly and process work asynchronously.
+4. Fetch the current file or folder from Box; do not trust an event payload as the final state.
+5. Persist the Events API cursor when polling.
+
+Test a valid event, duplicate event, invalid signature, and restart/catch-up path.

+"""Regression: multiplex gateway profile scoping + full-prompt wiring.
+
+Two scenarios for _agent_home's resolution order (#86313 post-merge findings):
+
+1. MULTIPLEX INVERSION (@kshitijk4poor): the messaging gateway hands every
+   agent the shared launch-home state.db but binds the profile home per turn
+   via the HERMES_HOME ContextVar (copy_context into the worker). A bound
+   override must WIN over the db-derived launch home, else the shared-db
+   fallback stomps the correct profile deterministically.
+
+2. BARE THREAD (the original #86313 fix): no override bound — the db-derived
+   home must still win over ambient env resolution.
+
+Plus the full-prompt wiring test (@helix4u): build_system_prompt_parts on a
+bare thread with the bot's session DB must produce a prompt whose identity
+(SOUL.md), skills block, and profile line ALL belong to the bot — reverting
+any single call-site wire breaks this test.

+from that physical id, so every rotation went cache-cold. The fix resolves

+"""Retention parity at the compaction boundary (#84718).
+
+Compaction re-injects the todo list verbatim (``TODO_INJECTION_HEADER`` +
+``TodoStore.format_for_injection``) while skill instructions are pruned down
+to ``[SKILL_PRUNED: ...]`` markers. The imperative crosses the boundary; the
+policy that governed it does not. These tests pin the coupling fix: when the
+compressed transcript carries prune markers AND a todo snapshot is being
+re-injected, the snapshot block must also carry an explicit instruction to
+reload those skills before acting on the preserved tasks.
+
+Invariants covered:
+
+* the notice names every pruned skill with its exact ``skill_view`` call;
+* skill guidance recovery now survives at least as well as the todo snapshot
+  (same message, same strip lifecycle);
+* the notice rides AFTER ``TODO_INJECTION_HEADER`` so the stale-snapshot
+  strip removes both together — repeated boundaries never accumulate;
+* deterministic and bounded — same input, same bytes; marker cap shared with
+  the summary re-injection path;
+* absent when nothing was pruned (zero recurring cost for clean sessions).

+#82154: on a subscription OAuth credential, Anthropic's server-side content
+filter rejected the first sentence of the built-in ``SKILLS_GUIDANCE`` prompt
+and surfaced the rejection as ``HTTP 400 "You're out of extra usage."`` —
+a billing-shaped message that sent users to buy quota they did not need.
+
+Bisected against the live API against the full 71,721-char assembled prompt:
+that sentence alone reproduced the 400, and removing it alone cleared it.
+Size (20 KB of filler → 200) and the ``system[0]`` identity gate (a 429, not a
+400) were both ruled out.
+
+These tests pin the reword. They deliberately assert on the *trigger substrings*
+rather than on an exact replacement string, so a future rewording is free to
+change the prose as long as it does not reintroduce the rejected phrasing or

+"""Regression tests for #88234 — CLI cleanup must NOT finalize a session that
+was handed off to the gateway.
+
+The handoff flow re-binds the CLI session_id to a gateway session_key via
+``switch_session``, which reopens the session row.  The CLI then exits and
+``_run_cleanup`` fires ``_notify_session_finalize`` on that same session_id.
+The resulting ``end_session`` call sets ``end_reason`` on a row the gateway
+just reopened and is actively writing to — the handoff leg vanishes from
+session history and ``session_search`` cannot find it.
+
+The fix adds a module-level ``_handed_off_session_ids`` set (mirroring the
+existing ``_single_query_finalize_attempted_session_ids`` pattern).
+``_handle_handoff_command`` registers the session_id when the handoff
+completes, and ``_should_emit_cleanup_session_finalize`` /
+``_emit_interrupted_session_end`` check the set before firing.

+"""Regression tests for #60920/#60941: interrupt marker duplication on redraw.
+
+The root cause: The interrupt marker ("_[Interrupted - processing new message]_")
+was being appended to the response string, which got recorded in _OUTPUT_HISTORY
+by the Panel rendering via _cprint → _record_output_history. When
+_recover_terminal_after_interrupt called _force_full_redraw → _replay_output_history,
+the marker was replayed on top of the already-visible message, causing duplicates
+that accumulated on every SIGWINCH.
+
+The fix:
+1. A flag ``_show_interrupt_marker`` is set instead of mutating ``response``.
+2. After the Panel rendering, the marker is printed via ``_cprint`` inside a
+   ``_suspend_output_history()`` context so it never enters ``_OUTPUT_HISTORY``.
+3. ``_recover_terminal_after_interrupt`` no longer clears ``_OUTPUT_HISTORY`` —
+   it doesn't need to, because the marker was never recorded.
+
+These tests verify the contract at the module level without hitting the full
+prompt_toolkit input loop.

+"""Regression tests for issue #87711 — Ctrl+key / Alt+key combos broken
+under modifyOtherKeys level 2.
+
+When the CLI pushes ``ESC[>4;2m`` (modifyOtherKeys=2) to supported
+terminals so Shift+Enter is distinguishable from Enter, the terminal
+re-encodes EVERY Ctrl+key combo as ``ESC[27;5;<codepoint>~`` instead of
+the raw control byte (``\\x01`` etc.). prompt_toolkit 3.x only ships a
+mapping for ``ESC[27;5;13~`` (Ctrl+Enter = Ctrl+M); all other Ctrl+letter
+combos are unmapped and leak as literal text or get swallowed.
+
+``install_modify_other_keys_aliases()`` populates ``ANSI_SEQUENCES`` with
+the full set so every Ctrl+combo continues to fire the same key binding
+the raw byte would.

+"""Regression tests for #88583 — one-shot resumed-session turns must persist.
+
+Bot Mode's bot-to-bot send (``hermes -p <bot> chat --in ~ -c "Bot Chat"
+--create-if-missing -Q -q "..."``) runs exactly one turn and exits. The
+receiving agent replied, the CLI banner said it resumed the titled session,
+but nothing landed in state.db when the turn's in-loop transcript flush
+failed transiently (write-lock contention with a multiplex gateway sharing
+state.db): the one-shot path had no end-of-run durable retry and never
+finalized the session row, unlike the interactive CLI (which retries on the
+next turn and ends the session with ``cli_close`` on quit).
+
+The fix routes every one-shot exit (quiet ``-Q -q``, human ``-q``, and the
+kanban SIGTERM path) through ``cli._flush_one_shot_session_store``: a final
+``_persist_session`` retry (idempotent via the per-message persisted
+markers), a token-count drain, and ``end_session(..., "cli_close")``.

+"""Regression tests for cooked-mode termios drift healing (cli._heal_cooked_mode_drift).

+Failure class: prompt_toolkit's ``run_in_terminal`` flips the tty to cooked
+mode for every "print above the prompt" window and restores raw mode after.
+If that restore is lost (cancelled coroutine, racing chained windows, an
+external actor), the terminal stays in cooked mode while the prompt_toolkit
+Application still believes it owns raw mode — the kernel line-buffers
+keystrokes and the CLI appears to stop taking input even though the process
+is healthy. Observed live on 2026-08-13 (session 20260813_113539_0f5b00):
+pts left in ``icanon echo`` after a background-review + bg-notification
+sequence, healed externally with stty.

+"""Tests for git self-heal: atomic worktree-add failure cleanup + pack maintenance.
+
+Regression for the Aug 2026 `hermes -w` timeout incident: 39 accumulated packs
+slowed object lookups until `git worktree add` blew its 30s timeout, and the
+timed-out add left a partially-materialized worktree plus a LOCKED admin entry
+(lock pid = the live hermes process), poisoning every retry.
+
+Two behaviors:
+1. `_cleanup_failed_worktree_add` — removes the partial dir, the admin entry
+   (even when LOCKED), and the orphaned branch, so a failed add is atomic.
+2. `_maintain_pack_health` — repacks when *.pack count reaches the sprawl
+   threshold; no-op below it.

+   scheduler looked perfectly healthy (heartbeat + success markers fresh)
+   while no job ever ran again.  Now the failure propagates to the ticker
+   loop, which records it and backs off.
+
+2. The ticker loop detects fd exhaustion (EMFILE/ENFILE/"Too many open
+   files"), attempts best-effort fd reclamation (``gc.collect()`` + raising
+   the soft nofile limit), and applies exponential backoff so an exhausted
+   process stops hammering the store every 60s.  Once FDs free up, the next
+   tick succeeds and the backoff resets — the scheduler self-heals without a
+   gateway restart.
+
+3. Genuine lock contention (EWOULDBLOCK/EAGAIN on flock) still skips the tick
+   silently — that behavior is preserved.

+"""Dead-owner cron claim reclaim + one-shot CLI `cron run` sync gate (#86721).
+
+A one-shot ``hermes cron run <job_id>`` used to background-dispatch the run
+onto a daemon thread of the calling process when the CLI inherited a
+gateway/desktop session env. The process exited immediately, the runner died
+mid-LLM-call, and the job's execution row stayed ``claimed`` forever —
+blocking every future run.
+
+Two-part fix under test here:
+
+1. ``hermes_cli.cron._job_action("run", ...)`` declares the channel stateless
+   before invoking the cron API, so the background-dispatch path is gated off
+   and the run executes synchronously to completion in the CLI process.
+2. ``cron.scheduler.tick`` periodically reaps execution rows whose owner
+   process is provably dead (``recover_interrupted_executions``), so a stale
+   ``claimed`` row from a crashed/exited owner auto-clears without a gateway
+   restart.

+"""RED-first regression test for the cron in-flight claim leak (t_27b59583).
+
+The leak
+--------
+``cron/scheduler.py`` tracks in-flight cron jobs in the module-level
+``_running_job_ids`` set. ``_submit_with_guard`` adds a job id BEFORE the
+future that owns its release exists: everything between the add and
+``pool.submit`` — ``create_execution``, ``contextvars.copy_context()``, and
+once running, the whole pre-future body of ``run_one_job`` (SessionDB
+construction around L3150-3161, agent import/build, config load) — has no
+``finally`` that discards the id. If any of it throws or hangs, the release
+path in ``_run_and_release``'s ``finally`` never runs. Every later tick then
+short-circuits with ``cron.scheduler: Job '<x>' already running — skipping``
+with no ``last_error``, no failure counter, and no alert, until the whole
+gateway process restarts (incident: jarvis ``board-pm-triage-*`` jobs,
+2026-08-02).
+
+This file is committed BEFORE the fix (red-first). Against the unfixed
+scheduler these tests MUST FAIL: the stale id is never released, so the
+primary assertion (``job_id not in get_running_job_ids()`` after a tick)
+fails. The implementation task (t_3778a491) makes them pass by adding the
+bounded stale-entry guard: on each tick, a claim older than
+``max(2 * interval, floor)`` with no live future is force-released, logged
+with a countable ``cron.inflight.forced_release`` signal, and surfaced via
+``mark_job_run(..., success=False, error=...)`` as ``last_error``.
+
+Design notes
+------------
+- The job store persists ``schedule`` as an already-parsed DICT
+  (``{"kind": "interval", "minutes": N}``), not the string form
+  ``parse_schedule`` consumes — the fixtures use the persisted dict shape.
+- The guard's age bookkeeping (``_running_since`` / ``_running_futures`` /
+  ``get_inflight_guard_stats``) does not exist yet on the unfixed scheduler.
+  The helpers reference it defensively (``getattr``/``hasattr``) so the SAME
+  file runs cleanly against both the red (unfixed) and the green (fixed)
+  implementation; the leak simulation is identical either way — an id in
+  ``_running_job_ids`` with no future ever installed.

+text-only on manual ``hermes cron run <job-id>``. Same box, same token, same
+scopes — the divergence is process context and error visibility, not
+credentials.
+
+Three defects, each pinned here:
+
+1. STANDALONE LANE SWALLOWS WARNINGS: platform standalone senders (Slack,
+   Discord, ...) report per-file upload failures in ``result["warnings"]``
+   while returning ``success: True``. ``_deliver_result`` only checks
+   ``result["error"]`` — an attachment failure vanishes: job marked ok, no
+   delivery error, text delivered, file gone.
+
+2. LIVE-ADAPTER LANE SWALLOWS MEDIA FAILURES: ``_send_media_via_adapter``
+   logs failed/skipped sends at WARNING and returns None — the caller
+   cannot surface them into delivery_errors either.
+
+3. MEDIA-POLICY ENV BRIDGE IS GATEWAY-ONLY: ``gateway.strict`` /
+   ``media_delivery_allow_dirs`` / ``trust_recent_files`` from config.yaml
+   are exported to the env vars ``validate_media_delivery_path`` reads ONLY
+   in gateway startup (gateway/run.py). A CLI-process manual run filters
+   MEDIA paths under different policy than the gateway's scheduled tick.

+"""Regression tests for #86522 — one-shot run_claim cleared on dispatch failure.
+
+``get_due_jobs`` stamps a ``run_claim`` on one-shot jobs before returning them
+as due (#59229); ``mark_job_run`` clears it on completion.  When dispatch
+itself fails (interpreter shutdown, execution-creation error, executor submit
+error) the job never reaches ``mark_job_run`` and the stale claim blocked
+re-dispatch until the TTL expired (default 30 min) — a precisely-timed
+one-shot reminder arrived up to 30 minutes late with no error surfaced.
+
+The fix (salvaged from PR #87591 by @RelaxJonh) adds
+``cron.jobs.clear_run_claim`` and calls it on all three ``_submit_with_guard``
+early-exit paths, wrapped best-effort so a failing store can never crash the
+tick these paths exist to protect.

+"""Deterministic reproduction of the recurring-cron EAGAIN in-memory wedge (t_8b5480b3).
+
+Scenario modelled on the 2026-08-14 incident: a recurring no_agent interval job
+whose script subprocess raises EAGAIN ([Errno 11] Resource temporarily
+unavailable) during a substrate thread-exhaustion spike. After the failure is
+recorded (terminal 'failed' execution row), the job must be re-dispatched on
+the NEXT tick once the substrate recovers — with no force-run.
+
+SCOPE NOTE (honest): this file exercises the in-memory EAGAIN-release class —
+the claim taken by ``_submit_with_guard`` is released when the submit/init
+path fails, so the NEXT tick re-dispatches. It passes on unfixed base because
+a terminal ``failed`` execution row does not itself suppress a recurring job's
+next due fire; that is pre-existing behavior, not the fix. The persisted-state
+(restart-surviving) half of the incident — a recurring job whose persisted
+``last_status=error`` and ``next_run_at`` parked in the future is never
+re-dispatched without force-run/resume — is covered by
+``test_recurring_persisted_error_recovery.py``, which provides the clean
+behavioral RED (unfixed: no execution) / GREEN (fixed: re-dispatched) for the
+new recovery path.
+
+This file drives the REAL `tick()` end-to-end against a throwaway HERMES_HOME:
+  tick 1 -> script EAGAINs (subprocess.run raises OSError 11) -> failed exec row
+  tick 2 -> substrate recovered (script runs clean) -> job MUST fire again

+by `mark_job_run` is invisible to the in-memory sweep: it is not in the
+running set (nothing force-releases it) and it is not due (so `get_due_jobs`
+never returns it).  It just sits — exactly the restart-surviving symptom
+documented in the incident.
+
+This recovery (cron/jobs.py `_get_due_jobs_locked`) re-arms `next_run_at` to
+now for a recurring job that:
+  * is in a persisted `last_status == "error"` state, AND
+  * has NOT re-fired within a full cadence (`last_run_at` older than
+    cadence + grace — so it is NOT a normal transient-error retry that will
+    fire on its own soon), AND
+  * is not currently running in this process.
+
+The scheduler then re-dispatches it on the next tick WITHOUT force-run/resume
+— the built-in equivalent of mech_red_guard's `cron resume`.
+
+Deterministic RED/GREEN: on unfixed code the wedged job is left untouched (no
+execution row, no re-dispatch); with the recovery it re-fires and completes.

+"""Deterministic reproduction of the recurring-cron wedge (t_8b5480b3) — RED/GREEN.
+
+The 2026-08-14 incident (t_20e23f84): 4 recurring no_agent interval jobs
+EAGAIN-failed at 12:50:05 and then recorded ZERO executions for ~1h47m while
+the scheduler ticked normally and fired 100+ other jobs — wedged in a
+non-dispatch state that even survived a gateway restart, cleared only by a
+manual force-run (`hermes cron run <id>`).
+
+Root cause class (t_3778a491, the SAME symptom on 2026-08-02): `_submit_with_guard`
+adds a job id to the in-memory `_running_job_ids` set BEFORE the future that
+owns its release exists. Anything that hangs or dies between the add and
+`pool.submit` (documented case: EAGAIN thread exhaustion on a substrate spike,
+or a wedged SessionDB.__init__ on a stale sqlite flock) leaks the claim. Every
+later tick short-circuits with "already running — skipping" silently — no
+execution row, no last_error, no counter — so the job is due-but-never-dispatched.
+
+The live deployment (origin/main) does NOT contain the t_3778a491 in-flight
+stale-claim sweep, so the wedge class is still live.
+
+This file drives the REAL `tick()` and asserts the fix's contract:
+  RED  (unfixed): a stale in-flight claim is never released by tick → the
+       wedge reproduces deterministically (job stays in the running set, no
+       execution, no re-dispatch without force-run).
+  GREEN (fixed):  the same stale claim is force-released by the next tick
+       (cron.inflight.forced_release) and the job re-fires — no gateway
+       restart, no force-run needed — and 2 consecutive auto-fires work.

+"""Session-boundary gating for background-process completion delivery.

+Plain ``type=completion`` events historically carried only ``session_key``

+The fix stamps the spawning conversation's session-db id on the watcher at
+spawn time and routes stamped events through the SAME pre-flight policy the
+async-delegation path already uses (``_classify_completion_target``):
+
+- terminal (user boundary such as /new)  -> drop with a log
+- retry (transient DB uncertainty)       -> watcher re-polls
+- deliver (live / idle-ended parent)     -> proceed as today

+"""Regression tests for #82161.

+``restart_drain_timeout`` defaults to ``0``, and the drain applied that single
+budget to every class of in-flight work. That default is deliberate for chat
+turns — the user is told the gateway is restarting and the session is
+pre-marked resume_pending, so interrupting one is cheap and recoverable — but
+a cron run has neither property: it is written to jobs.json as a permanent
+failure that nobody is waiting on, and a recurring job just skips to its next
+schedule.
+
+With the shared budget the drain short-circuited on ``timeout <= 0`` before
+the wait loop, producing the reported log line: ``drain took 0.00s,
+timed_out=True, cron_at_start=1, cron_now=1`` — it detected the job and killed
+it anyway. Cron work now drains on its own floor (``cron_drain_timeout``),
+clamped to the shutdown-watchdog leash so the extra wait can never eat the
+post-drain cleanup window.

+"""Regression tests for #82232.
+
+When the shutdown interrupts an in-flight cron job, the job's own worker
+thread tries to deliver an "interrupted" notice — and loses, because
+``_bounded_adapter_teardown`` has already closed the transport by the time it
+gets there. The notice is dropped, and ``_consume_interrupted_flag`` discards
+the resulting ``delivery_error`` with it, so the run's only trace is a line in
+jobs.json.
+
+The gateway now sends that notice itself in the post-interrupt phase, while
+adapters are still connected — the same window
+``_notify_active_sessions_of_shutdown`` uses for chat sessions, which never
+saw cron work because cron runs outside ``_running_agents`` (#60432).

+"""Regression tests for #82888 — internal synthetic turns are persisted typed.
+
+Async-delegation batch completions and background watch notifications re-enter
+the gateway as synthetic ``MessageEvent(internal=True)`` turns (see
+``_inject_watch_notification``). They must keep ``role='user'`` (message
+alternation is sacred) but the persisted row must carry
+``display_kind='internal_notification'`` so transcripts and the desktop UI can
+render them as timeline notices instead of user bubbles.
+
+Covered:
+
+1. an internal event threads ``persist_user_display_kind`` into the agent run;
+2. a real user event does NOT get the marker;
+3. the gateway-side fallback user rows (transient-failure / no-new-messages
+   paths) carry the marker for internal events only;
+4. a marked row round-trips through SessionDB replay with role='user' intact
+   and the marker is stripped from provider-bound payload copies.

+"""Regression coverage for #88532.
+
+A multiplexed gateway serves every profile from one process.  ``SessionStore``
+used to bind a single ``SessionDB`` during ``__init__``, freezing it to the
+process's own root home, so a named profile's sessions were physically written
+to the root ``state.db`` even though ``_profile_runtime_scope`` had already
+redirected ``get_hermes_home()`` for that turn.  The rows carried the correct
+``profile_name``, which is why the only visible symptom was the desktop listing
+a profile's session under the default bot: the desktop reads
+``profiles/<name>/state.db``, which never received the write.
+
+These tests pin the handle to the *active* scope rather than to construction
+time.  ``test_write_under_profile_scope_lands_in_profile_store`` is the one
+that reproduces the report; it fails against the pre-fix code with the session
+row sitting in the root store.

+2. weixin: repeated poll failures through a proxy strand sockets in the

+"""Regression tests for parallel platform connect at gateway startup (#83791).
+
+The old ``GatewayRunner.start()`` loop awaited each platform's connect()
+(including its own timeout) in turn. A single slow/failing platform (e.g.
+Telegram behind a dead proxy) therefore delayed every later platform's
+connect by a full timeout window, cascading one platform's failure onto
+WeChat/QQ/etc. These tests prove the connects now run concurrently.
+
+Why event-order, not wall-clock timings
+---------------------------------------
+An earlier version of this test recorded ``time.monotonic()`` around each
+connect() and asserted ``slow_start < fast_end``. That assertion is true in
+BOTH the serial and the parallel world, so it proved nothing:
+
+  serial:   slow_start=0, slow_end=0.300, fast_start=0.300, fast_end=0.300
+            -> 0 < 0.300  (passes, but it's serial!)
+  parallel: slow_start=0, fast_start=0,    fast_end=0.001, slow_end=0.300
+            -> 0 < 0.001  (passes)
+
+The only assertion that distinguishes them is ``fast_end`` occurring *before*
+``slow_end`` (true only when the two connects overlap). We record the
+connect start/end events in arrival order, which is fully independent of clock
+resolution -- ``time.monotonic()`` has only ~15 ms resolution on Windows
+(GetTickCount64), so parallel connects can land on the same tick and defeat any
+wall-clock comparison. Event ordering cannot be defeated by a coarse clock.

+"""Regression test for the Telegram lazy-install rebind path (#85272).
+
+When ``plugins.platforms.telegram.adapter`` is imported before
+python-telegram-bot is available, the top-level ``except ImportError`` block
+binds every SDK symbol to a placeholder. ``check_telegram_requirements()`` then
+lazy-installs the package and re-imports, rebinding those module globals.
+
+Any symbol the rebind misses stays a placeholder while ``TELEGRAM_AVAILABLE``
+flips to ``True``, so the adapter believes the SDK is present and fails at the
+first use of that symbol. ``TypeHandler`` was missed, and handler registration
+raised ``TypeError: Any cannot be instantiated`` — see #85272.
+
+The test drives the real transition rather than asserting on one name, so it
+also catches the next symbol that gets dropped from the rebind list.

+"""Legacy ``api_mode`` spellings must keep selecting the transport they named.
+
+Regression coverage for the silent api_mode vocabulary break: earlier
+releases accepted ``api_mode: openai`` on custom provider entries. The
+canonical set consumed by ``agent_init`` is now {chat_completions,
+codex_responses, anthropic_messages, bedrock_converse, codex_app_server},
+and an unrecognized value was silently ignored at BOTH consumption sites:
+
+* ``hermes_cli.config._normalize_custom_provider_entry`` passed the raw
+  string through, so ``agent_init``'s accepted-set check dropped it and
+  fell through to hostname detection.
+* ``hermes_cli.runtime_provider._parse_api_mode`` returned None, with the
+  same fall-through.
+
+For a host with a detection rule (e.g. api.actual.inc -> codex_responses)
+the provider silently switched transports after an update and broke:
+observed live as every reasoning-bearing request to a relay's untested
+/v1/responses endpoint failing while chat_completions worked. See the
+#66543 discussion.
+
+The fix canonicalizes known legacy/alias spellings through one shared map
+(``_canonical_api_mode``) at both sites. Unknown values still pass through
+unchanged (normalizer) / return None (runtime gate) so existing invalid
+config behavior is untouched.

+"""``bounded_probe_run`` — deadlock-safe capture for fail-open probes (#87134).
+
+On Windows, ``subprocess.run(..., capture_output=True, timeout=N)`` can hang
+FOREVER after its timeout fires: run()'s cleanup kills the direct child and
+then joins the pipe reader threads with an unbounded ``communicate()``.  A
+descendant (``conhost.exe`` under wmic/powershell, ``git.exe`` under a
+launcher shim) holding duplicated pipe handles keeps the pipes from EOF and
+the join never returns.  ``hermes update`` wedged exactly there inside
+``_scan_gateway_pids`` on machines where the full ``Win32_Process`` scan
+exceeds its budget.
+
+``bounded_probe_run`` is the shared, generalized form of the fix that
+``bounded_git_probe`` already proved for git probes (#68609 / #66037):
+explicit ``communicate(timeout)``, tree-kill on failure, bounded 1s drain,
+then abandon.
+
+These tests use REAL subprocesses (no mocks) for the semantics: a mock cannot
+reproduce pipe-handle inheritance or timeout behavior.  The POSIX-only
+descendant-survival cases live in ``test_git_probe_tree_kill.py`` and now
+exercise the same code path through the ``bounded_git_probe`` delegation.

+Regression for #86794: a background/quiet `hermes chat -c "<title>" -q "..."`
+against a not-yet-existing titled session silently no-oped — the error message
+was written to stdout (which quiet/programmatic callers treat as the "final

+titled session from the same invocation.
+
+Two behaviors are fixed here:
+
+1. **fail loudly on stderr** — when no session matches `-c <title>`, the error
+   goes to stderr (exit 1), so programmatic callers always see it.
+2. **--create-if-missing** — same invocation with the flag creates a fresh

+"""Deferred platform plugins must still register their *client* tools.
+
+Issue #78050: a bundled ``kind: platform`` plugin is registered as a deferred
+loader so ``hermes chat`` doesn't import ~20 gateway SDKs. The a2a plugin ships
+two independent things behind that one deferral — an inbound adapter (heavy)
+and five outbound client tools (``a2a_call``, ``a2a_discover``, ``a2a_list``,
+``a2a_history``, ``a2a_orchestrate``). Deferring the plugin deferred both, so
+in a CLI/TUI process the client tools never registered at all:
+``resolve_toolset("a2a")`` returned ``[]`` and the toolset was absent from the
+``hermes tools`` checklist. The same tools worked in gateway/web processes only
+because those materialize every platform at startup.
+
+Client tools that live in a dedicated ``tools`` submodule are now registered at
+discovery time; the adapter stays deferred.

+"""SessionDB bootstrap must never run schema init on an event-loop thread.

+Enterprise field report (2026-08-14): after an unclean shutdown plus a

+``SessionDB.__init__`` blocked the gateway's event-loop thread (reached via
+``_post_turn_goal_continuation`` → ``GoalManager()`` → ``load_goal`` →
+``_get_session_db``). The loop-liveness watchdog missed 3 probes and killed
+the process with exit 75; the supervisor restarted into the same state —
+an unbounded crash loop.
+
+Contract fixed here, at the shared boundary (goals.py ``_get_session_db``,
+which the heartbeat module reuses):
+
+- Called on a thread with a RUNNING event loop and no cached DB, it must
+  NOT construct SessionDB inline. It returns None immediately (callers
+  already degrade gracefully on None) and populates the cache from a

+"""Memory-aware kanban dispatch guard (OOF-30 / OOF-77).
+
+Two production incidents shared the same failure shape: no
+``kanban.max_in_progress`` configured, a busy board, and a small hosted VM —
+the dispatcher fanned out 26-31 concurrent workers, the host swap-thrashed,
+and the whole machine (dashboard included) became unreachable.
+
+Covers the two safeguards added in response:
+
+1. :func:`hermes_cli.kanban_db.derive_default_max_in_progress` /
+   :func:`hermes_cli.kanban_db.resolve_max_in_progress` — memory-derived
+   default global concurrency cap when the operator never set one.
+2. The live memory-pressure guard inside ``dispatch_once`` — critical
+   pressure spawns nothing; elevated pressure spawns at most one; unknown
+   imposes no restriction (fail-open).

+"""Regression tests for the quarantine no-op restore gap (#75584).
+
+On Windows, ``_run_quarantined_install`` / ``_run_install_cmd`` rename live
+``hermes*.exe`` shims aside (``hermes.exe.old.<ms>``) before invoking the
+installer so uv/pip can write fresh replacements. When the install SUCCEEDS
+but never rewrites entry points (uv audits an already-satisfied editable
+install as a no-op), the old code only restored the shims on FAILURE — the
+quarantined shims stayed renamed aside and ``hermes`` vanished from PATH
+after a green install.
+
+These tests exercise both wrapper sites with a fake installer and assert the
+shims come back on every path:
+  - success + installer rewrote shims  → fresh shims kept, .old garbage left
+  - success + installer wrote nothing  → original shims renamed back (the bug)
+  - failure                            → original shims renamed back (as before)

+while ``bitwarden.py`` imported cryptography at module level, so every
+Windows ``hermes update`` exited 2 before even fetching and the update
+looped forever (#86735 / #86780 / #86781).  The guard is now honest:
+
+* it only reports a loaded module when the dependency sync would actually
+  REWRITE that distribution (``_dependency_sync_would_rewrite`` — installed
+  version vs the on-disk pyproject pins);
+* it runs AFTER the code swap, immediately before the venv rewrite
+  (``_abort_dependency_sync_if_self_locked``), so a deferral leaves the

+"""The live-DB guard must survive a scrubbed child environment (#82770).
+
+Forensic background: a read-only sweep of production ``state.db`` files found
+hundreds of zero-message "open" gateway session rows carrying test-fixture
+identities (``chat-1`` / ``user-1`` / ``wx-chat``), with matching
+``gateway_routing`` scopes pointing at ``pytest-of-*`` temp directories.
+
+The escape is structural, not a one-off test bug.  Hermetic isolation rides
+entirely on the process environment: ``HERMES_HOME`` says *where* to write and
+``PYTEST_CURRENT_TEST`` / ``PYTEST_VERSION`` say *whether the guard is armed*.
+Both live in the same carrier, so a child spawned with a rebuilt environment
+loses them together — it aims at the developer's real ``state.db`` and
+silences the only check that would have stopped it, in one step.
+
+Process ancestry is the signal that survives an env rebuild, so these tests
+pin that the guard is armed by ancestry when the environment no longer says
+"pytest".
+
+These tests drive ``_ensure_test_isolation`` rather than constructing a real
+``SessionDB``: if the guard regresses, the assertion must fail *without* the
+test itself writing to the developer's live database.

+"""Behavioral tests for provider-confirmed compression-budget rearming.
+
+``compression_attempts`` is a shared per-turn backstop (pre-API gate,
+overflow/413 handlers, post-tool gate). Before the refund fix, *successful*
+pre-API compactions consumed it permanently: a marathon tool turn burned all
+attempts on compactions that worked, the pre-API gate went dark for the rest
+of the turn, and the context grew unchecked until the provider rejected the
+request terminally ("max compression attempts (N) reached").
+
+The budget is rearmed only when a completed compaction is followed by a real
+provider prompt count below the configured threshold. Rough estimates and
+usage-less responses cannot reopen the anti-thrash cap.
+
+These tests drive ``run_conversation()`` through real tool iterations — no
+source inspection, only observable compaction counts.

+"""Fallback activation must preserve the Anthropic wire signal (PR #79787).
+
+Three behaviors salvaged from PR #79787:
+
+1. An explicit ``api_mode`` on the fallback entry is honored — and always
+   wins, including an explicit ``chat_completions`` that would otherwise be
+   overridden by codex_responses / bedrock re-detection.
+2. ``fb_api_mode`` is detected from the ORIGINAL ``base_url`` hint before
+   ``resolve_provider_client`` / ``_to_openai_base_url`` can rewrite a
+   dual-surface ``/anthropic`` base to ``/v1``.
+3. ``api_mode`` is passed into ``resolve_provider_client`` at the fallback
+   call site so the resolver keeps the Anthropic wire for custom bases.

+"""Watermark commit: concurrent appends survive in-place compaction (#75316).
+
+The provider summary call is external and slow. Messages that arrive while it
+runs must (a) persist immediately — appends are not fenced by the compression
+lock — and (b) survive the commit: ``archive_and_compact(watermark=...)``
+re-sequences every active row above the watermark after the compacted set
+instead of archiving it. The commit is holder-fenced: a compression whose
+lease was reclaimed cannot publish a stale compaction.

+"""Regression: the Windows Desktop update hand-off must run through python.exe.
+
+`scripts/desktop-update/windows.ps1` drives `hermes update` for the in-app
+Desktop updater. It used to invoke the update through the venv's
+`venv\\Scripts\\hermes.exe` console-script launcher. On Windows that launcher is
+a real process that keeps `hermes.exe` mapped as its running image and spawns
+`python.exe` as a child. The update ends in `uv pip install -e .`, which rewrites
+the console-script shims -- including the `hermes.exe` the launcher still has
+mapped -- and Windows refuses to replace a file mapped as a running image
+("os error 32"). The rename fallback then defers to next reboot via
+`MOVEFILE_DELAY_UNTIL_REBOOT`, which needs elevation a Desktop-driven update
+does not have, so `uv pip install -e .` exits non-zero, the ZIP fallback repeats
+the same sequence, the desktop build stage is never reached, and the pre-build
+clean has already removed `apps/desktop/release` -- leaving an install whose
+Start Menu shortcut points at a `Hermes.exe` that no longer exists.
+
+Driving the update as `python.exe -m hermes_cli.main update` puts the inherited
+image handle on `python.exe`, which uv never has to replace, so the shim is an
+ordinary unlocked file when uv rewrites it.
+
+This test is source-level because Linux CI cannot execute the PowerShell
+hand-off. The invariant it guards is that every `Invoke-HermesStep` call site
+(the update, its retry, and the desktop rebuild) drives `$pythonExe`, never the
+`$hermesExe` shim. `hermes.exe` may still be *named* in the file for the
+step-2 unlock preflight -- that is a lock probe, not an invocation -- so we
+assert against the invocation sites specifically.

-"""A live compression lock must delay a concurrent append, not destroy the turn.
+"""Appends flow freely during compression; the commit preserves them (#75316).
 
-``append_message`` refused immediately when another writer held the session's
-compression lock. The conversation loop turns that into
-``session_persistence_failed`` and tells the operator to check disk space and
-permissions, when in fact the store is healthy and busy for a few seconds.
+HISTORY: ``append_message`` used to refuse while another writer held the
+session's compression lock, with a short busy-wait (#75264 → #75083). That
+fenced ordinary transcript writes behind a lease whose real job is stopping
+two COMPRESSIONS colliding — turns died as ``session_persistence_failed``
+whenever a slow provider summary overlapped an incoming message (#74568,
+#77386), and a stale lock from a dead PID blocked writes for the full TTL.
 
-The write lock already gets a patience budget for exactly this reason (#74478).
-A compression hold is even more bounded, since the lock row carries its own
-``expires_at``, so the same budget applies here.
-
-The sibling condition, a compressor finding its own lease gone, is permanent
-and must still fail fast rather than spin out the whole budget.
+CURRENT CONTRACT (watermark commit): appends never check compression_locks.
+``archive_and_compact()`` takes a watermark captured at compression start and
+re-sequences every row that arrived after it (the concurrent tail) back into
+the live transcript, atomically, instead of archiving it with the snapshot.
+The commit itself is holder-fenced: a compression whose lease was lost cannot
+publish.

+"""Regression: Install-Uv must surface installer errors and have fallbacks.
+
+Issue #69216: Windows installs died with only the generic message
+``uv installed but not found at ...\\bin\\uv.exe``.  Two root causes:
+
+1. ``Install-Uv`` piped the astral installer's entire output straight into
+   ``Out-Null`` (``2>&1 | Out-Null``), so any real failure -- download error,
+   corporate proxy block, AV quarantine, permissions -- was swallowed and
+   the user only ever saw the generic post-condition failure (first
+   identified in #69366).
+2. There was exactly one install source, ``astral.sh``.  Corporate proxies
+   commonly block astral.sh while the byte-identical installer published at
+   GitHub releases downloads fine (diagnosed by @gakugaku on #69216).
+
+The fix installs a three-rung ladder inside ``Install-Uv``:
+
+- Rung 1: astral.sh installer, output captured via ``Tee-Object``.
+- Rung 2: GitHub releases installer mirror, same ``UV_INSTALL_DIR``.
+- Rung 3: salvage an existing ``uv.exe`` (``Get-Command uv`` or
+  ``%USERPROFILE%\\.local\\bin\\uv.exe``) by copying it into
+  ``$HermesHome\\bin\\uv.exe`` so the managed-first invariant holds.
+
+Only after all three rungs fail does it error out -- and then it prints the
+tail of the captured installer output so the real cause reaches the user.
+
+install.ps1 only runs on Windows, so these tests lock the contract at the
+source-text level (same style as test_install_ps1_uv_powershell_host.py).

+"""Transaction-boundary regression for Windows venv recreation (#83149).
+
+Review finding on PR #83194 (egilewski): the rollback source (the parked
+previous venv) was deleted as soon as ``Install-Venv`` saw a working
+interpreter in the replacement — but ``Install-Dependencies`` is a separate,
+later stage (a separate *process* under the stage-per-process bootstrap) and
+every dependency tier or the baseline-import gate can still fail after that
+point. Deleting the backup early re-creates exactly the availability failure
+the transactional recreate exists to prevent.
+
+The contract locked here:
+
+* ``Install-Venv`` records the parked backup in ``venv.pending-backup``
+  instead of deleting it, and its stale-tree sweep excludes that backup.
+* ``Install-Dependencies`` restores the previous venv on failure
+  (``Restore-VenvBackup``) and commits the cleanup only after the
+  baseline-import gate passes (``Complete-VenvTransaction``).
+
+The script only runs on Windows, so Linux CI locks the contract at the
+source level, same approach as tests/test_install_ps1_venv_recreate_safety.py.

+"""``SessionDB`` must support ``with``, so an owning scope releases its fds.
+
+Historically a SessionDB handle could not be released by dropping the last
+reference: once its background token writer started, the instance pinned
+ITSELF two ways (the writer thread's bound-method target, and a strong
+``atexit`` drain hook that only ``close()`` unregistered), so ``__del__``
+never ran for exactly the instances that leaked ``state.db``/``-wal``/
+``-shm`` descriptors (#88033). The writer now retires after an idle window
+and the atexit hook is a weak reference, so abandoned handles are eventually
+GC-collectible -- but eventual collection is not deterministic release.
+
+Owning call sites are still expected to close explicitly; the ownership
+comments in ``run_agent.py`` and ``tui_gateway/methods_session.py`` say so in
+those words. This module pins the ergonomic half of that contract: an owner can
+scope a handle with ``with`` and be exception-safe by construction, instead of
+hand-writing a ``try/finally`` at each of the ~59 instantiation sites (#88033).
+
+Following ``test_session_db_read_conn_pool.py``, these assert on the
+``sqlite_safe_read`` tracking registry rather than on raw descriptor counts:
+SQLite's unix VFS parks a closed descriptor on a per-inode reuse list while any
+connection still holds POSIX locks on that inode, so descriptor counts lag the
+real connection count and make such assertions flaky.

+"""Regression test for #86632: cron's synchronous delegate_task fallback must
+return after the child completes — the automatic background review must not
+fire inside the delegated child.
+
+Field signature (issue #86632): a cron job's top-level ``delegate_task`` takes
+the #66617 stateless-channel synchronous fallback, the child finishes its turn
+normally (``Turn ended: reason=text_response``), and the delegation never
+returns to the parent — the heartbeat monitor goes stale and the cron
+inactivity watchdog kills the job.  Root cause (traced in the issue thread and
+fixed by the ``_delegate_depth`` guard in ``AIAgent._spawn_background_review``):
+the child's turn finalization spawned the automatic memory/skill background
+review fork.  Delegated children must never spawn that fork — it inherits the
+child's (often premium) model, replays the whole conversation, and its spawn
+inside the child's finalize path is the wedge site the cron watchdog kills.
+
+This exercises the REAL end-to-end #86632 path: a genuine ``AIAgent`` child
+(mocked LLM client) with the skill-review trigger armed, dispatched through
+``delegate_task(background=True)`` under a session runtime where async delivery
+is unsupported (cron), forcing the synchronous fallback.

+"""The streamable-HTTP transport must accept both SDK generations' arity.
+
+``streamable_http_client`` yields ``(read, write, get_session_id)`` on mcp 1.x
+and ``(read, write)`` on mcp 2.x. ``_run_http`` unpacked a fixed 3-tuple, which
+is 1.x's shape, so on 2.x every HTTP and SSE server failed its handshake with
+``ValueError: not enough values to unpack (expected 3, got 2)`` and parked after

+It survived review because the existing coverage
+(``test_mcp_client_cert.py``) fakes the transport with a 3-tuple — encoding the
+old shape into the test — and because the common server configs are stdio,
+which is a different code path entirely. So the assertion that matters is not
+"does the happy path work" but "does it work for *each* arity the supported SDK

+"""Tests for approvals.single_query_mode — configurable approval behavior for
+single-query (-q) sessions.
+
+Background (#86878): ``hermes chat -q "..."`` runs one turn and exits. cli.py
+exports ``HERMES_INTERACTIVE=1`` (needed for interactive sudo password
+prompts), which previously made ``_is_interactive_cli()`` report True in the
+approval gate. A -q run has NO user waiting to answer approval prompts, so a
+dangerous command just waited the full timeout (300s) then failed closed — and
+the agent was effectively forced to work around the block (often silently
+auto-approving via ``execute_code``, which auto-approves in non-gateway mode).
+``approvals.single_query_mode`` (default ``deny``, mirror of cron_mode) makes
+that decision deterministic and explicit.

+"""Regression tests: profile HERMES_HOME override in ephemeral agent threads (#50233).
+
+Why: normal prompt turns bind ``session['profile_home']`` via
+``set_hermes_home_override`` before ``run_conversation`` so the turn runs against
+the correct profile home. The two ephemeral RPC paths — ``prompt.background`` and
+``preview.restart`` — spawn a fresh ``AIAgent`` on a NEW thread, and the
+``HERMES_HOME`` ContextVar set on the session-create thread does NOT propagate to
+those threads. Without an explicit re-bind, a background/preview-restart turn under
+a non-default profile would run against the wrong home. This module locks in:
+
+  1. ``prompt.background`` re-binds ``profile_home`` for the ephemeral turn.
+  2. ``preview.restart`` re-binds ``profile_home`` for the ephemeral turn AND does
+     NOT close the ephemeral agent (a task-wide ``AIAgent.close()`` would kill the
+     background server the restart just started — maintainer problem #1).
+  3. Both paths RESTORE the override after the turn (reset token from set), exactly
+     like the normal prompt turn, and skip the bind entirely when no profile is set.
+
+How to test: run this module with pytest; each test drives the real RPC handler
+from ``tui_gateway.server._methods`` with ``threading.Thread`` patched to run the
+target inline, then asserts on the recorded override set/reset calls and the agent.

+"""Desktop image submit path must never block on vision calls (#83291).

+with the auxiliary vision model *before* the turn was dispatched — serial
+blocking calls of 60-90s per large photo, silent failure swallowing, and an
+interrupt window that killed the turn with zero API calls. The replacement
+``_build_image_ref_message`` only references the image paths so the agent
+analyzes them in-loop with ``vision_analyze`` (the same shape as the

+"""Tests: profiles.list ``preferred_session_ids`` precise session summaries.
+
+Why: the desktop BOTS roster previews ``last_session`` (the profile's most
+recently active session) but clicking a bot row opens the PINNED canonical
+chat — two different session identities, so the preview shows one
+conversation and the click lands in another (NousResearch/hermes-agent#88200).
+The generic fix at the RPC layer: callers that know which session they care
+about pass ``preferred_session_ids={profile: session_id}`` and receive a
+precise ``preferred_session`` summary per profile — hidden sessions included,
+compression lineages resolved to the live tip, no pagination window — while
+``last_session`` keeps its existing "most recent" contract.
+
+Contract under test:
+- A profile named in the map gets ``preferred_session``: a summary dict when
+  the id resolves, ``None`` when it definitively does not (missing row,
+  denied internal source).
+- Summary keys: ``id`` (the requested pin, durable identity), ``resolved_id``
+  (live compression tip; equal to ``id`` when uncompressed), ``title``,
+  ``preview`` (newest user/assistant text at the tip), ``started_at``,
+  ``last_active``, ``message_count``.
+- Profiles not named in the map carry no ``preferred_session`` key at all.
+- ``last_session`` behaviour is unchanged in every case.
+- ``include_sessions: false`` skips preferred resolution entirely.
+- Resolution reads each profile's OWN state.db (strict per-profile scoping).

+"""Bot Mode roster probe — canonical Bot Chat system prompt section.
+
+When the desktop's Bot Mode manages this install (any profile carries a
+``ui_meta['hermes-bots']`` block in its profile.yaml), a bot's canonical
+"Bot Chat" session — and ONLY that session — gets a short "Messaging other
+agents" section so the bot can receive teammate DMs, reply with attribution,
+and hand off @mentions.  Regular sessions never carry the section; the
+desktop's composer middleware owns the @mention send path there.
+
+The caller (agent/system_prompt.py) enforces the session-title gate against
+``BOT_CHAT_TITLE``; this module answers "is this install Bot-Mode-managed,
+and what should the section say for this profile".
+
+This replaces the plugin-side SOUL.md backfill: the protocol is injected by
+the core at prompt-build time instead of appended to user-authored SOUL
+files.  If the profile's SOUL.md already carries the section (created by an
+older plugin version), the probe stays silent so the text never doubles up.
+
+Silent (returns ``""``) when:
+- no profile on this install is Bot-Mode-managed (the dominant case),
+- the current profile's SOUL.md already contains the protocol heading,
+- anything at all goes wrong (never crash a prompt build).
+
+Deterministic within a process: the result is computed once and cached, so
+compression-triggered prompt rebuilds produce identical bytes.
+
+Toggle via ``agent.bot_mode_protocol`` in config.yaml (default True).

+        MCP 2026-07-28 replaced the ``initialize``/``initialized`` handshake
+        with a stateless core: every request is self-describing and clients
+        MAY probe ``server/discover`` up front (SEP-2575). The SDK exposes
+        both paths on ``ClientSession`` (``initialize()`` / ``discover()``)
+        and ``adopt()``s whichever result installs the outbound stamp, so
+        the rest of this file is era-agnostic.

+
+        - ``auto`` (default): try the legacy handshake FIRST, and fall back
+          to ``server/discover`` when the server signals it is modern-only
+          (``UnsupportedProtocolVersion`` -32022, or ``initialize`` missing
+          -32601). This is the reverse of the SDK's own discover-first auto
+          mode, on purpose: nearly every configured/catalog server today
+          speaks the handshake era, and initialize-first means ZERO extra
+          round-trips and zero behavior change for all of them, while
+          stateless-only servers still connect via the fallback.
+        - ``stateless``: probe ``server/discover`` first (one legacy retry
+          on MCPError, so a handshake-only server still connects).
+        - ``legacy``: handshake only, no fallback (escape hatch for servers
+          that misbehave on unknown methods).
+
+        Both result types expose ``.capabilities``, so downstream gates

+Plugin Guard — Security scanner for externally-installed plugins.
+
+Inspired by Claude Cowork's skill & plugin security scanning (announced
+2026-08-06: third-party skills and plugins are automatically checked for
+malicious content when someone uploads or edits them, returning pass /
+warn / fail). Hermes already scans hub-installed *skills* via
+``tools/skills_guard.py``; this module extends the same static-analysis
+engine to ``hermes plugins install`` and ``hermes plugins update``, which
+previously cloned and executed arbitrary Git repositories unscanned.
+
+Plugins are strictly more dangerous than skills — they run Python
+in-process with the agent — but they are also *expected* to do things a
+skill never should: read their own API keys from environment variables
+(the documented ``requires_env`` pattern), call provider HTTP APIs with
+those keys, and spawn subprocesses. A naive reuse of the skill threat
+patterns would flag every legitimate provider plugin. So this scanner:
+
+- Runs the full skills_guard pattern set on documentation/config files
+  (README, after-install.md, plugin.yaml, ...), where prompt-injection
+  and social-engineering content lives.
+- Exempts the "reads own env secret" / "HTTP call with key" pattern
+  family on *code* files, while keeping genuinely malicious signals:
+  foreign credential-store access (~/.ssh, ~/.aws, ~/.hermes/.env),
+  reverse shells, destructive commands, persistence mechanisms,
+  obfuscated execution, and known exfiltration services.
+- Applies plugin-sized structural limits and skips VCS/venv noise.
+
+Verdict → install policy (Cowork's pass/warn/fail, adapted):
+
+- ``safe``      → install normally.
+- ``caution``   → warn; requires explicit confirmation (interactive
+                  prompt, ``--force``, or a caller-supplied decision
+                  callback).
+- ``dangerous`` → blocked. ``--force`` does NOT override.
+
+Usage:
+    from tools.plugin_guard import scan_plugin, should_allow_plugin_install
+
+    result = scan_plugin(Path("/tmp/clone/my-plugin"), source="owner/repo")
+    allowed, reason = should_allow_plugin_install(result)

+"""Per-mutation skill audit ledger + single-edit rollback (tracker #79686 P3).
+
+Every skill mutation — regardless of actor — appends one JSONL entry to
+``~/.hermes/skills/.curator_ledger.jsonl`` describing who changed what, with
+before/after file manifests whose contents are stored content-addressed
+(sha256-deduped) under ``~/.hermes/.curator_backups/blobs/``.
+
+Design decisions (Teknium-approved):
+  - JSONL, not the state DB: the ledger is a durable, human-greppable audit
+    trail that survives DB resets and is trivially rsync/backup friendly.
+  - The ledger covers ALL actors, tagged ``curator`` / ``agent`` / ``user``.
+    The curator *invariant* (never hard-delete autonomously) is unchanged and
+    applies only to autonomous actors; foreground user deletes stay
+    hard-delete — but they are still ledgered so they're recoverable via
+    ``hermes curator rollback <entry-id>``.
+  - Per-file content-addressed blobs (not tarballs): a mutation typically
+    touches one file, so a whole-tree tarball per mutation would be wasteful,
+    and identical content across entries dedupes to a single blob.
+
+The ledger is TELEMETRY, NOT A GATE: a ledger failure must never block the
+mutation it describes. Every public write path here is wrapped so exceptions
+are logged and swallowed. The one deliberate exception is ``rollback_entry``,
+which FAILS CLOSED when its own pre-rollback safety capture fails (consistent
+with the whole-run tarball rollback in agent/curator_backup.py).

+"""Advisory NVIDIA SkillEvaluator Tier 1 scan for skill installs.
+
+Runs alongside (never instead of) the built-in skills guard
+(``tools/skills_guard.py``). The skills guard remains the enforcement
+layer — trust levels, install policy, block verdicts. This module adds a
+second, advisory opinion from NVIDIA's SkillEvaluator: deterministic,
+keyless Tier 1 static checks (PII, unicode smuggling, script lint).
+
+Design contract (deliberate):
+
+- **Warn, don't block.** PII-class findings (emails, personal paths,
+  connection-string placeholders) are shown to the user with file/line and
+  the install continues. The upstream PII scanner has known false-positive
+  classes (``git@github.com``, documentation example emails, ``op://``
+  secret-manager references), so its findings are surfaced as information,
+  never used to reject a skill outright.
+- **Prompt only for secrets-class criticals.** Findings that look like a
+  real leaked credential (private keys, cloud access keys, tokens,
+  credentialed connection strings) get one confirmation beat in
+  interactive installs. ``--force`` skips the prompt; non-interactive
+  installs (TUI/agent, ``skip_confirm=True``) proceed with a loud warning
+  rather than wedging on a prompt nobody can answer.
+- **Never break installs.** Scanner missing from PATH, crashing, timing
+  out, or emitting unparseable output all degrade to a no-op. The
+  built-in guard has already run by the time this executes.
+
+The scanner binary is optional::
+
+    uv tool install --python 3.13 \
+        "skillevaluator @ git+https://github.com/NVIDIA/SkillEvaluator.git@v0.1.0"
+
+Enable/disable via ``skills.tier1_advisory`` in config.yaml (default: on;
+a no-op unless the binary is installed).

+"""Session-backed MCP OAuth flows for the gateway (mcp.servers.oauth.*).
+
+This mirrors the *provider* OAuth model used by the dashboard
+(``/api/providers/oauth/{id}/start`` + ``/poll/{session_id}``) rather than the
+FastAPI-request-coupled MCP dashboard flow: a ``start`` primitive kicks off a
+background worker and returns ``{session_id, auth_url, flow}``; a ``poll``
+primitive reports ``{status: pending|approved|error}`` until the tokens land on
+disk for that server in that profile.
+
+The underlying token machinery is the *same* one the CLI ``hermes mcp login``
+uses — ``hermes_cli.mcp_config._probe_single_server`` under
+``tools.mcp_oauth.force_interactive_oauth`` — so no OAuth logic is reimplemented
+here. The only new piece is decoupling the two browser callbacks (authorization
+URL out, ``code``/``state`` back in) from a FastAPI ``Request``:
+
+* ``tools.mcp_dashboard_oauth.DashboardOAuthFlow`` already provides the two
+  thread-safe rendezvous points (``publish_authorization_url`` /
+  ``deliver_callback``). We reuse it verbatim as the bridge object.
+* Instead of routing the browser redirect through a FastAPI callback route, we
+  run a tiny loopback HTTP listener on ``127.0.0.1:<port>/callback`` and set the
+  flow's ``redirect_uri`` to it. When the provider redirects the user's browser
+  there, the listener calls ``flow.deliver_callback(...)``. This is the same
+  loopback strategy the CLI uses by default, just wired to the shared bridge.
+
+Client contract (what the desktop plugin does):
+  1. call ``mcp.servers.oauth.start(profile, name)`` → ``{session_id, auth_url}``
+  2. open ``auth_url`` in the native browser (``openExternal``)
+  3. poll ``mcp.servers.oauth.poll(profile, name, session_id)`` until
+     ``status == "approved"`` (tokens persisted) or ``"error"``.

+// SPACE marker) followed by the recomposed characters. The byte streams below
+// are real captures taken from OpenKey and EVKey on macOS while typing the
+// phrase "vương sỹ hạnh" (Telex: "vuonwg syx hanhj").
+//
+// The bug these guard against: characters were dropped and a stray space was
+// left mid-syllable (e.g. "hạnh" rendered as "hạ  "). Root causes fixed:
+//   1. parse-keypress split fused control-byte+text chunks so the recomposed

+//   2. textInput commits multi-character (IME/paste) inserts synchronously

+/**
+ * App-wide warning banner for resource trouble (NS-656): memory pressure
+ * and disk exhaustion.
+ *
+ * Triggers, worst-first:
+ * 1. Disk critical — the HERMES_HOME volume is nearly full. Worst because
+ *    the failure mode is silent data loss (SQLite writes failing, sessions
+ *    and config not persisting), not just a restart (OOF-2/OOF-107).
+ * 2. Memory critical — the gateway's heartbeat shows system memory in the
+ *    `critical` band right now.
+ * 3. Post-mortem — the previous gateway life died uncleanly and its last
+ *    heartbeat showed near-exhausted memory (`last_boot_suspected_oom`).
+ *    This is a heuristic, not proof the OOM killer acted — copy says so.
+ * 4. Disk elevated / 5. memory elevated — early warnings.
+ *
+ * All of this previously died in server-side log files; a hosted agent
+ * could be OOM-killed hourly or fill its disk completely while the
+ * dashboard looked healthy.
+ *
+ * Dismissal semantics (session-scoped, sessionStorage):
+ * - EVERY dismissal key embeds the reporting boot (`boot_id`), so a gateway
+ *   restart invalidates all of them. Without this, dismissing `critical`,
+ *   rebooting, and coming back still-critical would hide the NEW incident —
+ *   and mask the OOM notice too, since critical takes precedence. Disk
+ *   entries share the scheme: disk state has no boot relationship, but
+ *   re-surfacing a still-full disk after a restart is the desired behavior.
+ * - Within one boot, dismissal masks only the dismissed trigger; escalation
+ *   (elevated → critical, in either domain) re-opens immediately, and a
+ *   confirmed recovery (pressure back to "ok", not "unknown") clears that
+ *   domain's live dismissals so the NEXT episode in the same boot surfaces
+ *   again.

+ * Soft-keyboard inset math for the dashboard chat terminal (NS-434).
+ *
+ * Problem: when the on-screen keyboard opens on mobile, neither iOS Safari
+ * nor Android Chrome (default `interactive-widget=resizes-visual`) shrinks
+ * the *layout* viewport — the keyboard just overlays it. Our app shell is
+ * `h-dvh`, so the terminal host's bounding box doesn't change, `fit()`
+ * computes the same (cols, rows), and the PTY never re-lays-out. The Ink
+ * input line — drawn at the bottom of the grid — ends up hidden underneath
+ * the keyboard.
+ *
+ * The only reliable signal is `window.visualViewport`: its `height` shrinks
+ * to the visible region above the keyboard, and `offsetTop` reflects any
+ * visual-viewport scroll (iOS nudges the page when an input focuses). The
+ * keyboard inset is the part of the layout viewport below the visual one:
+ *
+ *   inset = layoutHeight - vv.height - vv.offsetTop
+ *
+ * ChatPage applies this as bottom padding on the terminal wrapper, which
+ * shrinks the xterm host → ResizeObserver refit → `term.onResize` sends
+ * `RESIZE` to the PTY → Ink redraws the input line above the keyboard.
+ *
+ * We also set `interactive-widget=resizes-content` in the viewport meta so
+ * Android Chrome 108+ resizes the layout viewport natively; there the inset
+ * computes ≈ 0 and this path is a harmless no-op. iOS ignores the directive
+ * and takes the JS path.

+ * and releases that pin the moment the user scrolls up so their manual review of
+ * the backlog is never yanked back down.
+ *
+ * These two decisions are pulled out here as pure functions so they can be

+#### Outbound client tools: `provides_tools`
+
+`kind: platform` plugins are **deferred**: the adapter module (and its SDK
+imports) only load when a gateway, cron, or `send_message` path first asks the
+platform registry for the platform. If your plugin also ships outbound *client
+tools* the agent should be able to call from any session (the bundled `a2a`
+plugin's `a2a_call` / `a2a_discover` etc.), put them in a dedicated `tools.py`
+with a `register_tools(ctx)` function and declare them in the manifest:
+
+```yaml
+provides_tools:
+  - my_platform_call
+  - my_platform_list
+```
+
+With `provides_tools` declared, Hermes imports only `tools.py` during plugin
+discovery and registers the client tools in every process — CLI and TUI
+included — while the adapter stays deferred. Keep the package `__init__.py`
+import-light and pull the adapter in from inside `register()` so the eager
+import stays cheap. Without the field, nothing changes: the whole plugin stays
+deferred.
+
+Users enable the toolset per platform like any other, e.g.
+`hermes tools enable my_platform --platform cli`, or by listing the toolset
+key under `platform_toolsets` in `config.yaml`. Plugin platform names are
+also valid `--platform` targets, so an inbound session on your platform can
+be granted its own outbound tools.

+### Transcript directives — inline components the model addresses
+
+`TRANSCRIPT_DIRECTIVE_AREA` makes the transcript itself a contribution area.
+Register a named directive and the agent can render your component inline in
+an assistant message by emitting a paragraph of the form `::name{key="value"}`:
+
+```javascript
+import { TRANSCRIPT_DIRECTIVE_AREA } from '@hermes/plugin-sdk'
+
+ctx.register({
+  id: 'task-card',
+  area: TRANSCRIPT_DIRECTIVE_AREA,

+    render: ({ attrs, streaming }) => jsx(TaskCard, { taskId: attrs.id, streaming })
+  }
+})
+```
+
+Rules the host enforces so the surface stays safe:
+
+- The directive must be the **entire paragraph** — `::name` mid-prose stays
+  prose, so plugin components can never hijack running text.
+- Attributes are **untrusted model output** (`key="value"` pairs, string-only).
+  Validate your own fields; render nothing on garbage rather than guessing.
+- An **unclaimed** directive (no plugin registered for the name) renders as
+  the plain paragraph it always was — nothing breaks when a plugin is off.
+- Renders are wrapped in the contribution error boundary: a throw degrades to
+  an inline error chip, never a dead message.
+- First registration wins on a name collision; namespace adventurous names
+  with your slug (`myplugin-board`, not `board`).
+
+Core ships one directive as the reference consumer: `::preview{file="…"}`
+renders the workspace HTML file **live inside the message** — a sandboxed
+`srcdoc` iframe with an opaque origin (scripts run and the widget is fully
+interactive; no reach into the app, its storage, or the bridge). The frame
+sizes itself to the content (height live, width adopted from the content's
+intrinsic span, flush left in the message flow), and a theme prelude hands
+the document the app's resolved tokens (`--foreground`, `--muted-foreground`,
+`--accent`, `--border`, `--card`), the app font, and a transparent
+background — so widget-shaped HTML reads as native while a full page keeps
+its own design. Non-HTML targets and remote gateways fall back to the
+classic preview card. Tell the agent about your directive in a skill (that's
+how it learns to emit it).
+
+Previewed widgets can also **talk back**. Inside the frame,
+`window.hermes.send('get-price eth')` (or a declarative
+`<button data-hermes-send="get-price eth">` — no script needed) hands that
+prompt to the agent as a user turn, off-screen: no bubble takes up the
+transcript, the widget updating is the visible response. The turn is still
+real — it wakes the agent, rides the composer's steer/queue rules, and
+persists (typed `hidden`) so resume and the session DB keep the full record.

 `host.request` is the same JSON-RPC the app itself uses (sessions, config, skills,
-cron, kanban, …). Profile-shaped plugins get first-class methods too:
+cron, kanban, …). `host.requestProfile` accepts a descriptor from
+`host.profileRoutes()` and routes that RPC through its exact registry source and
+profile without changing the active chat or gateway. The profile-only overload is
+retained only for the sole-local/legacy topology; registry-aware plugins should pass
+the descriptor so two sources exposing the same profile name cannot collide.
+
+`host.openWorkspace(id, { render, title?, minWidth?, onClose? })` docks a
+plugin-rendered view into the **main workspace zone** — the same center area
+session tiles and previews use — as a tab, and reveals it. Re-calling it with
+the same `id` refreshes the content in place and re-fronts the tab instead of
+opening a duplicate. Closing the tab (the tab's Close control or ⌘W) tears the
+registration down and fires your `onClose`; the returned disposer closes it
+programmatically. Feature-detect it (`typeof host.openWorkspace ===
+'function'`) and fall back to a regular contributed pane on older desktop
+builds — Bot Mode's group-chat rooms are the reference consumer (main-window
+takeover when available, in-panel view otherwise).
+
+`host.profileRoutes()` inventories every registered source in the current connection
+registry. Connect-on-demand SSH sources expose a credential-free `default` seed
+route without opening a tunnel, so a plugin can be the first caller that dials them;
+an SSH `remoteProfile` remains the route's backend `targetProfile`. `connectionId`
+is the registry routing identity;
+pair it with `profile` for keys and persistence. Endpoint, token, SSH host/key, and
+other raw connection fields never cross the plugin IPC boundary. `profile` is the
+source-local route used
+for requests; `targetProfile` is the backend Hermes profile served by that route.
+They differ when a route explicitly maps to another backend profile (for example an
+SSH `remoteProfile` override or a legacy per-profile URL alias). This distinction
+preserves backend identity without exposing connection secrets.
+
+Profile-shaped plugins get first-class methods too:
 `profiles.list` (each profile + its most recent conversation as
 `last_session`; pass `include_sessions: false` to skip the per-profile DB
-probe) and `profiles.create` (`name`, `description`, `clone_from`,
+probe; pass `preferred_session_ids: { profileName: sessionId }` for an
+exact, existence-checked lookup of one pinned session per profile — each
+named row gains a `preferred_session` summary that resolves hidden rows
+and compression lineages to their live tip, or `null` when the id is
+definitively gone; older gateways ignore the param and omit the field)
+and `profiles.create` (`name`, `description`, `clone_from`,
 `clone_all`, `no_skills`, `soul`, optional `model` + `provider` pin) — the
 ws twins of the dashboard's `/api/profiles` REST routes.
+`host.state.busy` is the focused chat's live turn (thinking and streaming).
+`host.state.awaitingResponse` stays true from send until the first assistant
+payload. Both follow the chat the user is actually looking at — the focused
+session tile when one holds focus, else the primary workspace chat (the same
+signal the statusbar's busy pulse reads). Subscribe in a component:
+
+```javascript
+const busy = useValue(host.state.busy)
+```
+
+For token-level detail, listen with `host.onEvent` (`message.start`,
+`message.delta`, `message.complete`).
+
 `host.onEvent` streams live gateway events (message deltas,
 session lifecycle, tool activity). Listeners are isolated — a throw in your
 listener can't affect app dispatch. Every `host` door is async-safe: a sync throw

+:::caution Contributor-operated distribution
+This APT repository is **community-maintained by `@adybag14-cyber` and is not an official NousResearch distribution**. NousResearch does not build, sign, host, or audit these packages. Enabling the repository means trusting the contributor-operated repository and its signing key. Termux itself remains a Tier 2 / best-effort platform.
+:::
+
+For users who prefer a native package-manager install rather than building Python/Rust dependencies on the phone, a community-maintained APT repository is available. The repository bootstrap and packaging sources are published in [`adybag14-cyber/termux-python`](https://github.com/adybag14-cyber/termux-python), with the Hermes package build in [`adybag14-cyber/termux-hermes`](https://github.com/adybag14-cyber/termux-hermes).

+Install the repository key/source and Hermes with:
+
+```bash
+curl -fsSL https://raw.githubusercontent.com/adybag14-cyber/termux-python/main/scripts/setup_apt_repo.sh | bash

+```text

+APT-managed Hermes installs are marked with install method `apt`. Hermes therefore does not run its Git self-updater against package-owned files; use the package manager instead:
+
+```bash
+pkg update

 A second, separate guard refuses to touch the venv while any process is running from its Python interpreter (the Desktop app's backend, a gateway, a Python REPL). Those processes keep native extension files (`.pyd`) locked, and a dependency sync that dies partway on an access-denied error strands the install between versions. This guard is **not** bypassed by `--force`; if you're certain the detected holders are false positives, use the explicit `hermes update --force-venv`.
 
+#### Windows venv recreation is transactional
+
+When the Windows installer must recreate an existing `venv`, it first moves the old directory to a unique `venv.stale.*` name, then creates and verifies the replacement. The old tree is deleted only after the dependency install completes and the baseline imports pass in the new tree — until then it is the rollback source (recorded in `venv.pending-backup`).
+
+If the move cannot be completed, the installer stops and leaves the live `venv` untouched. If `uv` fails or reports success without creating the interpreter, any partial replacement is moved to `venv.failed.*` and the previous venv is restored. This keeps the health and blocker checks usable after a failed install.
+
+A `venv.stale.*` or `venv.failed.*` directory can remain when another process still owns a file handle. Close Hermes Desktop, gateways, and Python processes using the install, then retry the install/update; parked directories are cleaned up best-effort after a successful recreation.

+
+#### Command-minted credentials (`key_cmd`)
+
+Enterprise gateways often issue short-lived bearer tokens (SSO/OIDC brokers, cloud IAM, internal auth proxies) rather than static API keys, so a token copied into `.env` goes stale mid-session and requests start returning 401. `key_cmd` names a command that *prints* a token; Hermes runs it and caches the result until shortly before expiry, so long sessions keep working with no restart:
+
+```yaml
+providers:
+  my-gateway:
+    base_url: "https://gateway.internal.example.com/v1"
+    api_mode: chat_completions
+    key_cmd: "my-auth-cli print-token --profile prod"
+```
+
+Works with any helper that prints a token — `databricks auth token`, `gcloud auth print-access-token`, `az account get-access-token`, `vault read`, or Claude Code-style `apiKeyHelper` scripts.
+
+The command must print **only** the token on stdout: either bare, or as JSON with an `access_token` field (`expires_in` is honored; absolute `expiry`/`expiresOn` ISO timestamps too). Multi-line output is rejected rather than guessed at. If no expiry is advertised, the token is re-minted on a bounded window.
+
+Precedence: an explicit `--api-key` flag still wins; otherwise `key_cmd` beats a static `api_key`/`key_env` on the same entry. The minted credential applies to the main agent turn and to auxiliary tasks (title generation, compression, vision, embedding) alike.
+
+Not to be confused with `secrets.command`, which runs a helper **once at startup** to populate env vars process-wide. Use that for a vault/keychain helper handing back many secrets; use `key_cmd` when one provider's credential must be re-minted *during* a session.
 
 :::note Legacy format
 Older configs used a top-level `custom_providers:` list instead. It still works — Hermes reads both — and `hermes update` auto-migrates it to the `providers:` dict (config v12). Field names differ slightly in the dict format: legacy `model` is `default_model`, and legacy `api_mode` is `transport`.

+## Add to Hermes link
+
+MCP vendors and docs can offer a one-click **"Add to Hermes"** button that opens the Hermes desktop app with a pre-filled server config, mirroring Cursor's `cursor://anysphere.cursor-deeplink/mcp/install` scheme:
+
+```text
+hermes://mcp/install?name=NAME&config=BASE64
+```
+
+- `name` — the server name. Must match `^[A-Za-z0-9._-]{1,64}$`.
+- `config` — the server config object as **base64url-encoded JSON** (standard base64 is also accepted). The decoded JSON must be an object with either a string `url` field (`http://`/`https://` only) or a string `command` field, and may carry any of the server keys documented above. Payloads over 32KB are rejected.
+
+Example (JavaScript):
+
+```js
+const config = { url: 'https://mcp.example.com/mcp' }
+const link = `hermes://mcp/install?name=example&config=${btoa(JSON.stringify(config))
+  .replace(/\+/g, '-').replace(/\//g, '_').replace(/=+$/, '')}`
+```
+
+Opening the link never installs anything by itself: the desktop app shows a confirmation dialog with the server name and the full pretty-printed config (with an extra caution for `command`-based servers, which run a local process), and the user must explicitly confirm. Existing server names are never overwritten — the user is asked to rename or cancel.

+title: "Bot Mode"
+description: "Turn your Hermes profiles into a roster of named Bots — each with its own chat, role, model, memory, skills, and avatar. Bots run routines, share group chats, and message each other."
+---
+
+# Bot Mode
+
+**Bot Mode** turns your [Hermes profiles](./profiles.md) into a roster of named **Bots**. Each Bot has its own role, model, memory, skills, and avatar; Bots run recurring routines, deliberate together in group chats, and message each other directly. Build a specialist Bot once and it is there forever, one click away.
+
+Bot Mode ships **built into the [desktop app](./desktop.md)** and is **on by default** — no install needed. It appears as a **Bots** tab next to Sessions, with a **Routines** tile docked beside the conversation.
+
+:::tip A Bot is a profile
+There is no new primitive to learn: a Bot **is** a Hermes profile — isolated config, memory, skills, credentials, and chat history under `~/.hermes/profiles/<name>/`. Bot Mode is a UI over that primitive, so everything you do in it is visible from the CLI too: `hermes -p <bot> chat` opens the same agent, and Bot routines appear in `hermes cron list`. No core patches, no background daemons, no extra storage.
+:::
+
+## The Bots pane
+
+The roster shows one row per agent profile: avatar, latest-message preview, and timestamp.
+
+- **Click a Bot** to land in its chat — every Bot has a canonical, persistent **Bot Chat** conversation that is created (and pinned) the moment the Bot is born.
+- **Sessions** (from a Bot's context menu) browses and filters that profile's 200 most recent stored conversations, without changing the primary click-to-chat flow.
+- **Active now** — a presence strip above the roster shows every Bot currently working: the gateway-busy profile plus any Bot that wrote within the last 90 seconds. Each chip opens that Bot's chat. The strip never reorders the roster and disappears when the fleet is idle.
+- **Search** filters the roster as you type.
+
+:::note The canonical Bot Chat is a forever-chat
+Typing `/new` (or `/reset`) inside a Bot's canonical chat would fork the relationship into a scratch session — the one thing Bot Mode promises never happens. The composer reroutes it to `/compact` instead: fresh working context, same conversation. Regular sessions on the same profile keep full `/new` freedom.
+:::
+
+## Creating a Bot
+
+Hit **New Agent** in the roster. The quick path is three fields — **Name**, **Title**, **Description** — and the Bot exists in seconds, introducing itself as the first message of its new Bot Chat.
+
+An **Advanced** disclosure opens the full capabilities surface:
+
+- **Clone from an existing profile** — start from another Bot's config, skills, SOUL, and memory, or pick **Fresh profile** for a clean start.
+- **Create empty** — skip the bundled skills entirely for a minimal profile.
+- **Model & provider pin** — give the Bot its own model. Any provider/model pair Hermes knows about works, and different Bots can run on different models side by side. Leave it unset to inherit from the launch profile.
+- **Custom SOUL.md** — the Bot's persona and standing instructions.
+- **Per-skill, per-toolset, and per-MCP-server enablement** — tick exactly the capabilities this specialist needs.
+- **Shared keys** — by default the new Bot shares one OAuth/token pool with the main profile, so credential refreshes cannot invalidate each other. (Older gateways copy credentials instead — still functional, just forked.)
+
+### Choosing which machine it lives on ("Create on")
+
+With more than one connection registered in [Settings → Connections](./multi-connection-desktop.md), the New Agent dialog grows a **Create on** picker. Pick a device and the profile is created on **that** machine's backend — your window never switches gateways. The new Bot then appears in the roster as a Connections Bot (with an `@name-device` handle when the name exists on several machines), and chatting with it routes to its own machine.
+
+With a single connection (the common case) the picker is hidden and the Bot is created on the machine you're connected to — exactly the old behavior.
+
+Remote-creation notes:
+
+- **Clone source** is a profile of the *target* machine (its `default`) — a remote box doesn't have your local profiles to clone.
+- The live Capabilities tab binds to your active gateway, so a remote-target draft uses the staged Skills/Tools/MCP checklists instead; both read the target machine's catalog.
+- Cancelling the dialog discards the draft profile on whichever machine it was created.
+
+**Edit Profile** (right-click a Bot) reopens the same surface on the live profile any time: avatar, title, description, model pin, skills, toolsets, MCP servers, and the full SOUL.md.
+
+**Duplicate** (right-click) makes a full clone of a Bot — config, skills, SOUL.md, memory, and its look. **Delete Profile** permanently removes one, behind the same destructive confirmation the desktop's profile menu uses; the default profile cannot be deleted.
+
+## Avatars
+
+Every Bot gets a face:
+
+- **Geometric faces** — 7 shapes × 10 colors, with blinking eyes that scan while the Bot works.
+- **An uploaded image** — any picture you like.
+- **An AI-generated portrait** — when an image backend is configured, generated in place (this rides the standard `image.generate` RPC and works over both local and remote gateways).
+- **A pixel pet** — a companion from the [petdex gallery](./features/pets.md) that bounces beside the avatar while the Bot is busy. Run `hermes pets` in a terminal to explore the gallery.
+
+A Bot's look, title, and description are stored in the profile's metadata on the backend, so the same Bot appears the same way on every desktop connected to that backend.
+
+## Routines
+
+The **Routines** pane attaches recurring tasks to the Bot that does them — "summarize my inbox every morning" lives next to the Bot responsible for it. A structured schedule picker builds the schedule (frequency first, then only the detail that matters), with an Advanced field exposing the raw Hermes schedule string.
+
+Routines are plain [Hermes cron jobs](./features/cron.md) namespaced `[bot:<name>] <routine>` — they also show up in `hermes cron list` and the core Cron page. Runs land in the Bot's own chat history, so the result is right where you would talk to that Bot anyway.
+
+## Groups and group chats
+
+Right-click a Bot → **Move to group** to organize the roster into labeled sections — pick an existing group or create one inline. Ungrouped Bots stay on top; groups follow alphabetically, and a group disappears when its last member leaves.
+
+**Open chat** on any group header (2–6 Bots) opens a shared room where the whole group coordinates:
+
+- Your message triggers up to **three serial rounds** of member turns. @-mentioned Bots respond (everyone responds when nobody is mentioned); each Bot replies briefly or passes, and the room settles when a full round stays silent.
+- Bots pull each other in with `@name`, and escalate real judgment calls to you with `@user` — the group header shows a **needs you** badge when that happens.
+- Hard caps (10 messages per send, 3 rounds) keep rooms from spinning.
+- Each member keeps its own persistent `Group: <name>` session, so room context survives like any other conversation.
+- **Not every Bot replies to every message.** Speaking is each member's own choice — a Bot replies only when it has something new to add and passes otherwise, and @-mentioning specific members scopes the round to them. Expect the members you addressed (or whoever has something to say) to speak, and the rest to stay quiet.
+- **Rooms can span machines.** The New Group Chat picker seats Bots from any registered connection; each member's turns run on its own machine, in its own `Group: <name>` session there. Cross-machine members carry a device badge (`dixie · Mac Mini`) in the room and in other members' transcripts, and the disambiguated `@name-device` handle works in room mentions — so same-named agents on two machines never blur together.
+
+## Bot-to-bot messaging
+
+Bots message each other with attribution, and you can hand work off from any chat:
+
+- **@mentions** — type `@researcher have a look at this` in any chat and the active Bot hands the message off, waits for the reply, and reports back. Mention names are validated against the live roster, so an email address or an unknown `@` passes through untouched.
+- **@mentions across machines** — mentioning a Bot that lives on another registered connection (use its `@name-device` handle when names collide) delivers over the Connections registry in the background: the active Bot stays on this device, the desktop routes the message to the recipient's machine, and the reply is relayed back attributed to that agent. Your window's gateway never switches.
+- **Direct messages** — a Bot reaches a teammate's Bot Chat through the standard CLI: `hermes -p <bot> chat --in ~ -c "Bot Chat" --create-if-missing -Q -q "Message from 🤖 <sender> (@<sender>): ..."`. The receiving Bot sees the message the next time it runs and knows how to reply, because the messaging protocol is part of its Bot Chat system prompt.
+
+The backend teaches each Bot's canonical Bot Chat session the messaging protocol automatically at prompt-build time — including when a teammate opens it headlessly from the CLI. Only the canonical Bot Chat gets the protocol section; your regular sessions and your SOUL.md stay untouched. This is controlled by `agent.bot_mode_protocol` in `config.yaml` (default: on):
+
+```yaml
+agent:
+  bot_mode_protocol: true   # inject the bot-to-bot messaging protocol into canonical Bot Chats
+```
+
+:::note
+Bot-to-bot delivery is per-invocation: the receiving Bot picks the message up when it next runs. Live interrupt of a Bot mid-conversation is future work.
+:::
+
+### Bot-initiated DMs across machines (`hermes peer`)
+
+Bots on one machine can message Bots on **another machine's gateway** without any desktop in the loop. Register the other gateway as a *peer* (its API server URL + `API_SERVER_KEY`):
+
+```bash
+hermes peer add spark --url http://spark.lan:8377 --key <API_SERVER_KEY>
+hermes peer list
+hermes peer dm spark "Message from 🤖 dixie (@dixie): disk status?"
+hermes peer dm spark/researcher "..."   # named profile on a multiplexed peer
+```
+
+`hermes peer dm` delivers into the remote agent's canonical Bot Chat over the peer's existing API server, runs one agent turn there, and prints the reply on stdout — the exact cross-machine twin of the local `hermes -p <bot> chat` command.
+
+Once a peer is registered, the messaging protocol taught to every Bot Chat (`agent.bot_mode_protocol`) automatically includes the peer roster and the `hermes peer dm` pattern — so **your bots learn on their own** that teammates exist on other machines and how to reach them. Registering or removing a peer refreshes each Bot Chat's protocol on its next message (capability epoch).
+
+Requirements: the peer machine runs the `api_server` gateway platform with a strong `API_SERVER_KEY`; reachability is your network's business (LAN, Tailscale, VPN). The key is a credential and lives in `~/.hermes/.env` as `HERMES_PEER_<NAME>_KEY`; peer names/URLs live in `config.yaml` under `bot_peers`.
+
+## Bots across machines
+
+When you register several backends in **Settings → Connections** — the local runtime, remote gateways, SSH hosts, Hermes Cloud instances — the roster shows the Bots from **every** connected source, persistently: SSH sources are inventoried without spawning anything on the remote box, and machines that are momentarily unreachable keep their last-known rows instead of vanishing. When the same profile name exists on several sources, handles disambiguate as `@name-device` (for example `@research-homelab`). A Bot's chats, sessions, memory, and routines live on the machine that owns the profile.
+
+Clicking a Connections Bot does **not** hop your window onto that machine — stay in your chat and `@mention` it, seat it in a group chat, or create new agents on it directly with the **Create on** picker. Cloud and local agents share one roster this way: register your Hermes Cloud instance and your desktop (say, over Tailscale or SSH) and their Bots can message each other and sit in the same rooms, with each agent's work running on its own machine.
+
+See [Connecting Desktop to Many Hermes Instances](./multi-connection-desktop.md) for the full multi-connection guide.
+
+## Turning it off
+
+Bot Mode is a bundled desktop plugin. Flip it off in **Settings → Plugins → Bots** — the roster, the Routines pane, and the composer middleware unregister live, no restart needed. Your profiles, sessions, and cron jobs are untouched either way; Bot Mode never owns your data, it only renders it.
+
+There is also a preference to hide the canonical Bot Chats from the regular sidebar session list, so they only appear inside the Bots pane. (This uses the core hidden-session flag; on older gateways the chats simply stay visible.)
+
+## CLI parity
+
+Because Bots are profiles, everything has a terminal equivalent:
+
+| In Bot Mode | From a shell |
+| --- | --- |
+| Chat with a Bot | `hermes -p <bot> chat` |
+| A Bot's files, skills, memory | `~/.hermes/profiles/<bot>/` |
+| Routines | `hermes cron list` (jobs named `[bot:<name>] …`) |
+| Create / inspect profiles | `hermes profile create`, `hermes profile list` |
+
+See [Profiles](./profiles.md) for the underlying primitive and [Profile Commands](../reference/profile-commands.md) for the full CLI reference.

+Hermes maps its existing approval UX onto cua-driver's immutable runtime
+modes. Permission mode, capability manifest approval, and the existing-profile
+grant are launch settings. They cannot change after the runtime starts:
 
 | Hermes session | cua-driver mode | Human intervention | `existing_profile` |
 |---|---|---|---|
-| Manual or smart approvals (default) | `standard` | Normal Hermes approvals; Cua stops at its protected boundary | Refuses unless a certified protected host is available; Hermes does not claim one today |
-| `--yolo`, `/yolo`, or `approvals.mode: off` | private `unrestricted` daemon | One explicit Hermes risk acceptance; no runtime Cua prompts | Allowed within Cua's built-in, managed, and user policy ceilings |
+| Manual or smart approvals (default) | `standard` | Normal Hermes approvals; Cua stops at its protected boundary | Refuses unless `computer_use.grant_existing_profile: true` (one-time config opt-in) |

+| `--yolo`, `/yolo`, or `approvals.mode: off` | private `unrestricted` daemon | One explicit Hermes risk acceptance; no runtime Cua prompts | Refuses unless `computer_use.grant_existing_profile: true`; YOLO does not substitute for this grant |
 
-The unrestricted daemon is private to that Hermes session. Turning `/yolo`
-off, resetting/closing the session, cancellation cleanup, or process exit ends
-the Cua session and stops that daemon. It never changes the machine-wide
-daemon's mode or grants another Hermes conversation the same authority.
+### Attaching to your signed-in browser
 
-`smart` approval remains `standard`: an LLM classification is not protected
-human consent. Cua's `bounded` manifest mode is also not inferred from smart
-approval or a normal tool confirmation; it needs a separately trusted host
-that reviews and launches the exact manifest.
+The agent can drive a Chrome/Edge window you already have open — including a
+signed-in profile — **without restarting the browser, copying the profile, or
+touching your tabs**. Because DevTools access exposes that profile's live
+pages, cookies, and storage, cua-driver requires an explicit human grant that
+ordinary tool approval cannot substitute for. You opt in once, in config.yaml:
+
+```yaml
+computer_use:
+  grant_existing_profile: true
+```
+
+Hermes then launches the cua-driver runtime with the trusted-launcher grant
+(`--grant existing-profile`), and
+`cua_browser_prepare` with an existing profile succeeds against the exact
+`(pid, window_id)` the agent proves. Leave it `false` (the default) and
+existing-profile attachment fails closed; driver-owned isolated profiles work
+either way and are what the agent prefers.
+
+### Bounded mode for repeatable automation
+
+For recurring browser automation (cron jobs, scheduled research against an
+authenticated app), `bounded` mode uses a capability manifest you review once:
+
+```yaml
+# config.yaml
+computer_use:
+  permission_mode: bounded
+  capability_manifest: ~/.hermes/cua-manifest.yaml
+```
+
+The manifest names the apps, browser profile kinds, allowed origins, and
+typed tools the session may use (see the
+[cua-driver permission modes reference](https://cua.ai/docs/reference/cua-driver/permission-modes)
+for the format). Hermes launches a private runtime with
+`--capability-manifest ... --approve-capability-manifest`; anything outside
+the manifest fails closed inside cua-driver. A missing or unreadable manifest
+fails loudly at session start rather than silently downgrading. Session YOLO
+still overrides bounded for that one session.
+
+Each MCP transport owns a private lifecycle session inside its runtime. A
+public session name is only a label for cursor identity and session-scoped
+state. It does not select, share, or keep a runtime alive. Turning `/yolo` off,
+resetting or closing the Hermes session, cancellation cleanup, or process exit
+closes that transport session. Hermes also stops private runtimes that it
+launched for bounded, unrestricted, or existing-profile access. One Hermes
+conversation cannot change another runtime's mode or grants. On macOS, a
+standard runtime with an existing-profile grant uses a fresh CuaDriver.app
+daemon on a private socket. Bounded and unrestricted modes use a private
+embedded service under the Hermes host identity.
+
+`smart` approval remains `standard`: an LLM classification cannot stand in for
+a reviewed manifest or a launch-time grant.

+    name="Agent Tooling Scout",
+)
+```
+
+The first run has no previous output, so the prompt runs as-is. On later runs the previous output is prepended with continuity framing ("avoid repeating what was already reported"). It combines freely with upstream jobs (`context_from=["<other_job_id>"]` plus `continuity=true`), and `continuity=false` on update turns it off while preserving other `context_from` entries.

+## Missed scheduled fires (`last_fire_error`)
+
+On hosted (managed-cron) deployments, a scheduled fire travels from the platform scheduler through the dashboard to the gateway's internal API server. If that final hand-off fails — the gateway process is down, or its API-server listener never started — the run never begins, so there is no execution record and no `last_status` to inspect. The tell-tale shape: the job works every time you trigger it manually, but never auto-fires.
+
+These misses are stamped on the job record as `last_fire_error` (timestamp + reason) and surfaced by:
+
+- `cronjob` tool → `action: "list"` — the `last_fire_error` field
+- `hermes cron list` — a red `⚠ Missed scheduled fire:` line under the job
+- The dashboard job view
+
+The stamp always reflects **current** auto-fire health: it is overwritten by newer misses and cleared automatically by the next successful run. If you see it, the job and its schedule are fine — the gateway side of the fire path needs attention (most commonly, restart the gateway through its supervisor so it loads the full profile environment: `hermes gateway restart`).
+
+### Misfire catch-up
+
+When an external scheduler provider is active (managed cron on hosted deployments), the gateway also runs a catch-up sweep: a job whose scheduled time passed with no fire delivered — and whose grace window has elapsed — is claimed and run locally, so an outage in the fire hand-off costs minutes instead of the whole day. The sweep is de-duplicated against late scheduler retries by the same store claim used for normal fires.
+
+```yaml
+cron:
+  misfire_grace_minutes: 10   # wait this long for the scheduler's own retries
+                              # before catching up locally; 0 disables catch-up
+```
+
+Local (built-in ticker) deployments don't need this — the ticker already picks up past-due jobs on its next tick.

 ## Schedule formats
 
 The agent's final response is automatically delivered to the job's `deliver:` target — the agent no longer fires messages itself, so the user-facing content simply goes in the final response. To deliver to **additional or different** targets, list multiple `deliver:` targets on the cron job (comma-separated, e.g. `deliver: "telegram,discord"`) rather than having the agent send them.

+## Audit ledger and single-edit rollback
+
+Whole-run snapshots answer "undo everything the last curator pass did" — but sometimes you want to know *who changed what* and undo exactly one mutation. Every skill mutation — curator auto-transitions, agent `skill_manage` calls, and your own CLI archive/restore/purge — appends one entry to the append-only JSONL ledger at `~/.hermes/skills/.curator_ledger.jsonl`:
+
+- **actor** — `curator` (background review fork / auto-transitions), `agent` (foreground agent tool calls), or `user` (CLI commands)
+- **action** — `create`, `edit`, `patch`, `delete`, `write_file`, `remove_file`, `archive`, `restore`, `purge`, `rollback`
+- **evidence** — delete intent (`absorbed_into` for consolidations, empty for prunes, and whether the recoverable-archive path handled it), triggering session id when available
+- **before/after** — per-file `{path, sha256}` manifests. File contents are stored content-addressed (deduped by hash) under `~/.hermes/.curator_backups/blobs/`, so a hundred entries touching the same unchanged file cost one blob.
+
+```bash
+hermes curator ledger                  # newest 20 entries
+hermes curator ledger --skill my-skill --limit 50
+hermes curator rollback <entry-id>     # restore that one mutation's before-state
+```
+
+Single-entry rollback restores exactly the files that mutation touched (and removes files it created) from the blob store — nothing else in the skills tree moves. Like whole-tree rollback, it takes a safety ledger entry of the current state first and **fails closed**: if the safety capture can't be written, nothing is changed. Because foreground deletes are ledgered too, `hermes curator rollback <entry-id>` can resurrect a hard-deleted skill.
+
+The ledger is telemetry, never a gate — if writing an entry fails, the mutation still goes through. Disable it with:
+
+```yaml
+skills:
+  ledger: false
+```
+
+## Archive TTL purge
+
+Archived skills are kept forever by default. If you want `~/.hermes/skills/.archive/` bounded, set a TTL and purge explicitly — purging never runs automatically, and every purged skill is captured into the ledger (with blobs) first, so even a purge leaves an auditable, recoverable trail:

Completed tasks also send the first line of the worker's `--result` so you see the outcome without having to `/kanban show`.

+description: "Re-run a prompt on a recurring interval inside your session — Hermes' take on Claude Code's /loop."
+---
+
+# Recurring Loops (`/loop`)
+
+`/loop` re-runs a prompt (or a slash command) on a recurring cadence **inside your current session**. Each wakeup is a real agent turn: Hermes reads the current state fresh — the latest CI result, the newest queue depth, the file as it is now — does the work, reports back, and goes quiet until the next tick.
+
+It's Hermes' take on **Claude Code's `/loop`** (and its `/proactive` alias, which works here too). Where [`/goal`](./goals.md) is judge-driven — "keep working until this objective is achieved" — `/loop` is timer-driven: "do this again every N minutes (or whenever it makes sense) until something says stop."
+
+## When to use it
+
+- **Polling external state.** "Watch the deploy / the CI run / the queue and tell me when it changes." The canonical use case.
+- **Iterate-until-green.** "Run the tests, fix what fails, repeat until they pass."
+- **Monitoring during a work session.** Keep an eye on error rates or a long job's progress while you do something else in the same conversation.
+- **Periodic housekeeping.** Re-run a lint pass or a status summary every N minutes during a long session.
+
+When the work should run **unattended** — overnight, on a real schedule, surviving restarts of your terminal — use a [cron job](./cron.md) instead. `/loop` lives inside a session; cron lives outside all of them. And when the task is a single objective with a definition of done, [`/goal`](./goals.md) is usually the better fit.
+
+## Quick start
+
+```
+/loop 5m check the deploy status and tell me if it's live yet
+```
+
+What you'll see:
+
+1. **Loop accepted** — `↻ Loop set (every 5m): check the deploy status…`
+2. **First wakeup in 5m** — while the session is idle, Hermes injects the wakeup and runs a normal turn against current state.
+3. **Repeat** — every 5 minutes, until a stop condition fires or you stop it.
+
+Loop a slash command just as easily:
+
+```
+/loop 10m /recap
+```
+
+## The two cadence modes
+
+**Fixed interval — you set the clock.** Give an interval (`30s`, `5m`, `2h`, `1h30m`) and the loop fires on that schedule. Use it when the thing you're watching changes on its own timeline:
+
+```
+/loop 2m poll the build at ci.example.com/job/42 and ping me the moment it finishes
+```
+
+**Self-paced — Hermes sets the clock.** Omit the interval and the loop paces itself: it starts at the floor (1 minute by default), and while the agent's replies stop changing it backs off exponentially — 2m, 4m, 8m, up to the ceiling (15 minutes by default). The moment a reply differs from the last one, cadence snaps back to the floor. Change detection is a local digest comparison (timestamps are ignored), so idle waits cost nothing extra:
+
+```
+/loop keep an eye on the migration and summarize progress
+```
+
+The rule of thumb: **fixed interval when an external clock drives the work; self-paced when the work drives the rhythm.**
+
+## Stop conditions
+
+A loop ends when any of these fires:
+
+| Condition | How |
+|---|---|
+| The agent decides it's done | The wakeup prompt teaches the agent to end its reply with `LOOP_COMPLETE` on its own line when the task is finished or moot. |
+| A run cap | `--times N` — stop after N wakeups. |
+| An evidence-based condition | `--until <condition>` — after each wakeup, the same auxiliary judge that powers `/goal` checks the reply against your condition (fail-open: a broken judge never wedges the loop). |
+| You | `/loop stop` (or `/loop pause` to keep it around). |
+| The backstop budget | `loops.max_ticks` (default 100) pauses the loop so an unattended session can't burn tokens forever. `0` = unlimited. |
+
+Examples:
+
+```
+/loop 2m poll CI --times 30
+/loop 5m watch the queue --until queue depth reaches zero
+```
+
+## Commands
+
+| Command | What it does |
+|---|---|
+| `/loop [interval] <prompt> [--times N] [--until <cond>]` | Start (or replace) the loop for this session. |
+| `/loop` or `/loop status` | Show cadence, ticks fired, and time to the next wakeup. |
+| `/loop pause` | Stop firing without losing the loop. |
+| `/loop resume` | Pick it back up. |
+| `/loop stop` | End the loop. |
+| `/proactive …` | Alias for `/loop` (Claude Code parity). |
+
+Works on the CLI, the TUI (`hermes --tui`), the web dashboard chat, the desktop app, and every gateway platform (Telegram, Discord, Slack, WhatsApp, …). On messaging platforms the gateway fires wakeups even between your messages — the loop belongs to the chat's session, and its results arrive as ordinary replies.
+
+## Mixing with `/goal`
+
+Both features inject synthetic turns at idle boundaries, so they follow one rule: **an active goal owns the session.** While a `/goal` is actively driving (judge saying "continue"), loop wakeups defer. The loop resumes using idle time as soon as the goal finishes, pauses, or parks itself on a wait barrier (`/goal wait`, or the judge's automatic WAIT verdict). A parked goal plus a `/loop` is a natural combo: the goal waits on the big async thing while the loop keeps a heartbeat on something else.
+
+A real user message always wins over both — wakeups only fire while the session is idle and nothing of yours is queued.
+
+## Behavior details
+
+- **A wakeup is a normal user-role turn.** No system-prompt mutation, no toolset swap — prompt caching stays intact.
+- **Survives `/resume` and compression.** Loop state persists per session and migrates across context-compression boundaries, same as `/goal`.
+- **One loop per session.** Setting a new `/loop` replaces the old one. Run several loops by running several sessions (or use cron for a fleet of schedules).
+- **Interrupting a wakeup turn (Ctrl+C) pauses the loop** — recoverable with `/loop resume`, so cancel actually means cancel.
+- **Token cost scales with cadence.** Every tick is a full agent turn. Match the interval to how often the state actually changes; prefer self-pacing for idle waits.
+
+## Configuration
+
+```yaml
+# ~/.hermes/config.yaml
+loops:
+  min_interval_seconds: 30       # floor for fixed intervals
+  max_ticks: 100                 # backstop budget (0 = unlimited)
+  self_paced_floor_seconds: 60   # self-paced starting cadence
+  self_paced_ceiling_seconds: 900  # self-paced max backoff
+```
+
+The `--until` judge routes through the `goal_judge` auxiliary task, so `auxiliary.goal_judge.*` overrides (provider, model, max_tokens) apply to loop conditions too.
+
+## `/loop` vs `/goal` vs cron
+
+| | `/loop` | `/goal` | cron |
+|---|---|---|---|
+| **Trigger** | Timer (or self-paced) | Judge verdict after each turn | Schedule, outside any session |
+| **Lives in** | Your current session | Your current session | Its own session per run |
+| **Ends when** | Stop condition / caps / you | Goal achieved / budget / you | You remove the job |
+| **Best for** | Polling, monitoring, periodic re-runs | One objective, iterate until done | Unattended, long-horizon schedules |

+Two behaviors apply to every MCP tool result before the model sees it:
+
+- **Invisible Unicode TAG characters are stripped.** Characters in the U+E0000–U+E007F range render as nothing in terminals and chat UIs but are fully visible to the model — a classic prompt-injection smuggling channel for a malicious or compromised server. Hermes strips them from tool results, resource content, and tool descriptions. Legitimate emoji tag sequences (regional flags like 🏴󠁧󠁢󠁳󠁣󠁴󠁿) are preserved.
+- **Vendor `_meta` is surfaced; protocol-reserved keys are not.** When a server attaches a `_meta` mapping to a tool result (vendor namespaces like `com.example/handoff`), Hermes passes it through to the model alongside the result content. Keys under protocol-reserved prefixes — a `modelcontextprotocol` or `mcp` label followed by another label, e.g. `modelcontextprotocol.io/...` or `tools.mcp.com/...` — are dropped, matching the MCP spec's key-name rules.

+In addition to the built-in security scanner (which enforces the install
+policy above), Hermes can run [NVIDIA SkillEvaluator](https://github.com/NVIDIA/SkillEvaluator)
+Tier 1 checks on every hub install as a second opinion. Tier 1 is
+deterministic and keyless — PII detection (leaked emails, personal paths,
+connection strings), unicode-smuggling detection, script lint, license
+compliance, and a static security scan via
+[NVIDIA SkillSpector](https://github.com/NVIDIA/SkillSpector).
+
+The scan is **advisory only**: findings are printed with file and line
+before the install confirmation, and the install continues. Findings that
+look like real credentials (private keys, cloud access keys, tokens,
+credentialed connection strings) are highlighted in red so you can review
+the flagged lines before deciding. PII-class findings are informational —
+the upstream scanner has known false-positive classes (e.g.
+`git@github.com` SSH syntax, documentation example emails), so they never
+block anything.
+
+To enable it, install the optional scanner binaries (the second one powers
+the `security` check; without it that check simply reports "not run"):
+
+```bash

 ## External Skill Directories
 
 If you maintain skills outside of Hermes — for example, a shared `~/.agents/skills/` directory used by multiple AI tools — you can tell Hermes to scan those directories too.
@@ -373,6 +412,49 @@ Paths support `~` expansion and `${VAR}` environment variable substitution.
 
 All four skills appear in your skill index. If you create a new skill called `my-custom-workflow` locally, it shadows the external version.
 
+## Project-Local Skills
+
+Repos can carry their own skills, active only for sessions started inside that project — the same pattern other agent harnesses use for repo-local configuration. When you launch Hermes inside a git checkout, it looks for skills in:
+
+```text
+<project-root>/.hermes/skills/    # Hermes-native location
+<project-root>/.agents/skills/    # cross-tool convention (shared with other agent CLIs)
+```
+
+The project root is the nearest ancestor directory containing `.git` (worktrees and submodules count).
+
+### Trusting a project
+
+Skills are procedure documents the agent follows, so Hermes does **not** auto-load them from arbitrary cloned repos. The first time you run Hermes in a repo with project skills, the banner shows a notice:
+
+```text
+◆ 3 project skill(s) found in /home/you/myproject but not loaded — run `hermes skills trust` to enable them.
+```
+
+Trust the repo once (from inside it, or by passing the path):
+
+```bash
+hermes skills trust             # trust the current repo
+hermes skills trust ~/myproject # or explicitly
+hermes skills untrust           # revoke
+```
+
+Trusted roots are stored in `skills.trusted_project_dirs` in `~/.hermes/config.yaml`. Set `skills.project_discovery: false` to turn the feature off entirely (no scanning, no notices).
+
+### Precedence
+
+Project skills are the **highest-precedence tier**: `project → local (~/.hermes/skills/) → external_dirs`. A project skill named `deploy` overrides a same-named profile or bundled skill for sessions inside that repo — that's the point: vendored repo skills win on their home turf, without touching your global profile. Project skills are tagged `[project]` in the agent's skill index so provenance stays visible.
+
+Like external dirs, project skill directories are treated as repo-owned: autonomous skill maintenance (the curator) never modifies them, and new agent-created skills always go to `~/.hermes/skills/`.
+
+### Scan-time quarantine
+
+Trust is a repo-level decision, but a repo's skill content changes with every `git pull`. To close that gap, every project skill is scanned with the same security scanner used for Skills Hub installs before it enters the index. A skill whose scan verdict is **dangerous** (prompt-injection directives, credential-exfiltration commands, hidden-text tricks) is quarantined: it does not appear in the skill index, `skills_list`, slash commands, and refuses to load by name with an explanatory error. Scans are content-hash cached under `~/.hermes/cache/project_skill_scans/` (never inside your repo) and re-run automatically when the skill's content changes.
+
+### Non-interactive surfaces (cron, API, ACP)
+
+Cron jobs and other non-interactive surfaces inherit your interactive trust decision — they never prompt and never auto-trust. The project root resolves from the surface's working directory (a cron job's `workdir`, via the same mechanism the terminal tool uses). A cron job whose `workdir` is inside a repo you previously trusted loads that repo's project skills; a job in an untrusted or undecided repo loads none.
+

+## Tool result annotations
+
+A few tool behaviors are worth knowing when you read agent transcripts:
+
+- **Signal deaths are explained.** When a terminal command is killed by a signal, the result carries a human-readable note instead of a bare numeric code — e.g. exit `-9`/`137` becomes "terminated by signal 9: SIGKILL — often the kernel OOM killer on memory exhaustion, or an explicit kill -9", and segfaults, aborts, SIGTERM, broken pipes, and CPU/file-size limits are labeled the same way. Negative codes (subprocess semantics) are stated definitively; the shell's `128+signum` convention is hedged with "usually" since an application can legitimately exit with those codes.
+- **UTF-16 text files are transcoded, not refused.** `read_file` detects UTF-16 (BOM or byte-pattern heuristic, either endianness — common for Windows Notepad files and PowerShell `>` redirects) and transcodes it to UTF-8 for display instead of flagging the file as binary. The result includes a hint disclosing the conversion; edits via `patch`/`write_file` re-encode as UTF-8. Files over 10 MB and genuinely binary files still get the binary-file refusal.

+# Connecting Desktop to Many Hermes Instances
+
+Register every Hermes backend you own — the local runtime, remote gateways on
+your LAN or VPS, SSH hosts, and Hermes Cloud instances — in one desktop app,
+and use the agents on all of them side by side. Connections are persistent:
+each registered source dials its own backends and WebSockets on demand, and
+background agents keep streaming while you look at another source.
+
+This is the desktop-side complement to
+[Running Many Gateways at Once](./multi-profile-gateways.md): that page is
+about hosting several gateways on one machine; this one is about one desktop
+app talking to several machines.
+
+## Where to find it
+
+Everything lives on the unified **Settings → Gateways** page (older builds had
+separate **Gateway** and **Connections** pages; legacy Connections deep links
+redirect there). Three doors lead to it:
+
+- **Settings → Gateways** — the page itself (**Cmd/Ctrl+,**, then
+  **Gateways** in the settings nav). The connections registry is a section
+  of that page, below the connection-mode and per-profile override controls.
+- **The sidebar profile rail** — the plug button at the right end of the rail
+  (tooltip: **"Connect another Hermes gateway…"**) deep-links straight to
+  the Gateways page. It is always visible, even before you have created
+  a second profile or a second connection.
+- **The command palette** — **Cmd/Ctrl+K**, then type *Gateways* (also
+  matches *connections*, *add gateway*, *remote*, *ssh*, *instances*).
+
+## The connection registry
+
+The registry section of **Settings → Gateways** manages a named list of agent
+sources. The
+pane's intro says it plainly: *"Register every place your agents live — this
+device, remote gateways on your network, and Hermes Cloud instances. All of
+them are stored here."* Each entry is a *connection*:
+
+| Kind | What it is | Auth |
+|---|---|---|
+| **Local** | "The Hermes runtime managed by this app." | automatic |
+| **Remote gateway** | "A Hermes gateway reachable over HTTP(S) — LAN, Tailscale, or the internet." | session token or OAuth |
+| **SSH** | "A Hermes install reached over SSH." The app opens the tunnel and starts the dashboard for you | SSH key + adopted token |
+| **Hermes Cloud** | "A hosted instance discovered through your Hermes Cloud account." | portal sign-in |
+
+Rules worth knowing:
+
+- **Every connection needs a unique device name** ("Homelab", "Work laptop").
+  The name shows up everywhere the instance appears — roster badges, handles,
+  update results. Uniqueness is case-insensitive, so `Homelab` and `homelab`
+  cannot coexist.
+- The **local** entry is managed by the app (it wears a **This device** pill)
+  and cannot be removed. Removing any other connection tears down its live
+  backends and tunnels; the instance itself is untouched.
+- One connection is always the **Primary** (pill on its row): it owns the
+  app-managed window backend — boot overlay and install/update machinery.
+  **Make primary** on any row retargets that; removing the primary falls back
+  to the local entry.
+- **Test** probes the connection's own HTTP *and* WebSocket legs, so a pass
+  (the *"Reachable"* toast) means chat will actually work — not just that the
+  host pinged.
+- **Duplicates are rejected when you save**: there is only ever one **local**
+  entry; **remote** and **cloud** entries are deduplicated on the normalized
+  URL (trimmed, trailing slashes stripped, lowercased — and across both
+  kinds, so a cloud entry and a remote entry can't point at the same URL);
+  **SSH** entries are deduplicated on the normalized `user@host:port` plus
+  remote profile.
+- Cloud entries normally come from the Hermes Cloud sign-in/discovery flow at
+  the top of the Gateways page — the **Hermes Cloud** kind in the add-connection
+  editor points you there.
+
+As the pane's own caption notes: *"Chats and the agent roster follow the
+source you pick; the app-managed window backend is still chosen by the
+connection-mode controls above."*
+
+## Adding a connection, step by step
+
+1. Open **Settings → Gateways** and scroll to the connections registry (or
+   click the plug in the profile rail).
+2. Click **Add connection**.
+3. Pick the kind: **Local**, **Hermes Cloud**, **Remote gateway**, or **SSH**.
+   (**Local** is disabled while the app-managed local entry exists — which is
+   almost always; **Hermes Cloud** directs you to the cloud sign-in/discovery
+   flow above.)
+4. Fill the fields:
+   - **Name** — required, unique; the "device name" shown everywhere this
+     instance appears (placeholder: `Homelab`). Max 64 characters.
+   - *Remote gateway only:*
+     - **Gateway URL** — the base URL of a running `hermes serve` backend,
+       e.g. `http://homelab.lan:9119`. Reverse-proxy path prefixes work.
+     - **Authentication** — choose **Session token** or **OAuth**:
+       - **Session token** — paste the dashboard session token from the
+         remote gateway. When editing, *"Leave blank to keep the saved
+         token."*
+       - **OAuth** — sign in through the Nous Portal browser flow; no token
+         to paste.
+   - *SSH only:*
+     - **SSH host** — one composite field in `user@host:22` form (user and
+       port optional). Your SSH key is used; the app adopts a dashboard
+       token over the tunnel.
+5. Click **Save connection** (or **Cancel**).
+6. Click **Test** on the new row and wait for *"Reachable"*.
+
+Edit any non-local entry later with the pencil button, or remove it with the
+trash button — removal asks for confirmation and reminds you that *"The
+instance itself is not touched — you can add it again any time."*
+
+:::info The remote backend is a running `hermes serve` process
+Nothing here works unless the backend is actually up and reachable on the
+other machine. The desktop app attaches to it; it does not start it for you
+(except for SSH connections, where the app starts the dashboard over the
+tunnel on demand). See
+[Connecting to a remote backend](./desktop.md#connecting-to-a-remote-backend)
+for backend-side setup — auth providers, binding to a non-loopback address,
+and Tailscale guidance.
+:::
+
+### Migrating from the single-connection settings
+
+The first launch of a registry-capable build imports your existing settings
+automatically: the global connection mode and any per-profile overrides from
+the old Gateway settings become named registry entries (deduplicated by
+URL/host).
+The legacy settings file is left untouched, so older builds on the same
+machine keep working. If a migrated name collided, it was suffixed
+(`Homelab 2`).
+
+## Agents across sources
+
+Every [profile](./profiles.md) on every registered connection is an *agent*.
+The union roster is what multi-source surfaces (and the built-in
+[Bot Mode](./bot-mode.md) roster) render:
+
+- When the same profile name exists on several sources, handles disambiguate
+  as **`@name-device`** — `research` on your Homelab renders as
+  `@research-homelab`, while a profile unique across all sources keeps its
+  bare name.
+- Enumeration is eager but sockets are lazy: the app lists agents over REST
+  without dialing every source's WebSocket. An unreachable source reports
+  per-row instead of breaking the roster; SSH sources stay connect-on-demand
+  until you first open an agent on them (no surprise tunnels).
+- Opening an agent dials **its own source** — chats, sessions, and memory
+  live on the machine that owns the profile, exactly as if you were using
+  that instance directly.
+
+Each `(connection, profile)` pair gets its own backend and socket, pooled
+with the same idle-reaping as local per-profile backends — background agents
+keep streaming while you look at another source.
+
+### Switching and scoping
+
+Switching agents is the same gesture as switching profiles:
+
+- **The profile rail** at the sidebar foot switches the active profile; the
+  home pill returns to the default profile and the layers pill shows the
+  **All profiles** view. **Cmd/Ctrl+1–9** switch profiles from the keyboard.
+- The sidebar's session list, cron jobs, and messaging status are **scoped to
+  the active profile** — and, for agents on another source, to that source's
+  machine. Sessions you see under `@research-homelab` live on the Homelab;
+  its cron jobs run there; its messaging channels are the ones its gateway
+  hosts. The **All profiles** view merges every profile's sessions into one
+  list, with per-profile tags.
+- Hovering an agent pre-warms its backend so the switch doesn't pay a cold
+  boot.
+
+## Updating every instance at once
+
+**Settings → Gateways → Update all instances** (shown once more than one
+connection is registered) dispatches `hermes update` to every eligible
+connection in parallel:
+
+- **Local** updates through the app's own update pipeline (the same flow as
+  Settings → Updates).
+- **Remote and SSH** connections are told to update themselves via their own
+  backend — the update runs on *that* machine.
+- **Hermes Cloud** instances are skipped with a *"Managed by Hermes Cloud"*
+  note: the platform manages their versions.
+
+Each instance reports independently, so one unreachable box never wedges the
+batch. Backends that manage updates externally (Docker, Nix) refuse politely
+with their own message, per row.
+
+## Security notes
+
+- **Where tokens live.** Remote-gateway session tokens are encrypted at rest
+  with Electron's `safeStorage` (the OS keychain — Keychain on macOS, DPAPI
+  on Windows, the session keyring backend on Linux) and stay in the Electron
+  main process; the renderer and plugins never see token bytes. OAuth tokens
+  for native sign-in are stored the same way, keyed by gateway base URL, and
+  refreshed automatically before expiry.
+- **Keyring-less Linux.** On a Linux session without a usable keychain the
+  app cannot encrypt the token; saving one raises an explicit opt-in dialog
+  before it will store the
+  token in plain text.
+- **The registry file** (`connections.json` under the app's user-data
+  directory) holds labels, URLs, and hosts — secrets only ever appear inside
+  encrypted envelopes.
+- The plugin SDK's `host.connections()` deliberately returns labels, kinds,
+  and the primary id — never token material.
+
+## For plugin authors
+
+The Desktop [plugin SDK](../developer-guide/desktop-plugin-sdk.md) exposes the
+multi-source surface directly:
+
+- `host.connections()` — the registered connection list (labels, kinds,
+  primary; never token bytes).
+- `host.agents()` — the union roster: one row per `(source, profile)` with
+  the precomputed `@name-device` handle.
+- `host.ensureAgent(connectionId, profile)` — activate an agent's gateway so
+  subsequent `host.request` calls hit its backend.
+- `host.warmAgent(connectionId, profile)` — fire-and-forget socket pre-warm
+  (hover-intent).
+
+All four are feature-detected: on an older Desktop build they're absent and a
+plugin should fall back to the single-source `profiles.list` flow. Bot Mode's
+multi-source roster is the reference consumer.
+
+## Troubleshooting
+
+- **"Connection test failed"** — the backend isn't reachable at that URL from
+  this machine. Check that `hermes serve` is running on the remote host, the
+  port is open, and (for token auth) the token is current. Re-run **Test**
+  after fixing.
+- **An agent shows but won't open** — run **Test** on its connection. The
+  WebSocket leg failing while HTTP passes usually means a proxy, firewall, or
+  gateway auth/origin guard is blocking `/api/ws`.
+- **A remote source is missing from the roster** — its backend is down or
+  unreachable; the roster lists it under sources with the error. SSH sources
+  show *connect-on-demand* until first use — that's by design, not a failure.
+- **"Update Hermes Desktop to chat with agents on other connections"** — the
+  app predates the multi-connection stack; update the desktop app itself.
+- **Duplicate device names** — not possible; names are enforced unique at
+  save time. If a migrated name collided, it was suffixed (`Homelab 2`).
+- **"Could not save the connection"** — most commonly a missing **Name**, a
+  name already in use, or a malformed **Gateway URL** / **SSH host**; the
+  error message names the exact violation.

+
+# Box
+
+Use Box as the cloud file system for file operations, collaboration, metadata, and document work. Run operations with Hermes' `terminal` tool and use the Box CLI; use the SDK guide when building an application.
+
+## When to Use
+
+- Organizing, uploading, versioning, moving, sharing, or collaborating on Box files and folders
+- Searching Box content or existing metadata
+- Asking questions about Box files, extracting metadata, or generating text grounded in a file
+- Processing a Box folder at scale without downloading every source file
+- Building a Box-backed application, integration, or webhook handler
+
+## Start broad file-system conversations
+
+When someone is exploring a cloud file system for Hermes, first give a short fit assessment: Box is useful when a team needs cloud file storage, sharing, search, metadata, and document work. Then ask whether they want to connect a Box account with OAuth or build a Box-backed application or integration with an SDK.
+
+OAuth makes Hermes act as the Box account authorized in the browser. That account's Box permissions determine what Hermes can access. To give Hermes narrower access, authorize an account that is invited only to the required files, folders, or Hubs.
+
+Do not run setup, show a command cookbook, propose account plans or folder taxonomies, or load every reference for a broad exploratory question. Wait for the user's answer, then load only the relevant path. When a request already names a concrete outcome, skip this discovery step and handle that outcome directly.
+
+Start normal CLI work with the official Box CLI OAuth app. It covers ordinary content work and Box AI. Use a custom **User Authentication (OAuth 2.0)** Platform App only when the requested operation needs an additional OAuth scope, such as webhook management. This remains an OAuth flow; do not substitute a server-side or impersonation identity.
+
+## Perform chosen setup interactively
+
+When a user selects an authentication path or asks Hermes to connect Box, perform the setup through `terminal`; do not turn the next response into instructions for the user to copy. Take the next safe action yourself, and pause only for an approval, browser sign-in, administrator action, or secret that Hermes cannot safely supply.
+
+- If `box` is missing, ask for any terminal approval required to install `@box/cli` under the current Hermes home at `tools/box-cli`; then verify it with the shell-appropriate command in [CLI guide](https://github.com/NousResearch/hermes-agent/blob/main/skills/productivity/box/references/cli-guide.md). Do not attempt a global npm install, use `sudo`, change npm's global prefix, or change `PATH`.
+- Before OAuth, ask: **“Is Hermes running on the same computer as the browser you will use to authorize Box, or on a remote host such as a VPS, container, or cloud VM?”** Use normal `box login` only for the same-computer path. Use `box login --code` only for the remote/headless path. Do not infer runtime topology from the operating system alone; read [OAuth setup](https://github.com/NousResearch/hermes-agent/blob/main/skills/productivity/box/references/oauth-setup.md) after the user answers.
+- Before starting browser authorization, state that Hermes will act as the Box account signed in there. If the user wants narrower access, they can authorize an account that is invited only to the required files, folders, or Hubs. Do not make that account an administrator to unlock an exceptional operation.
+- If a custom OAuth Platform App is necessary, use the CLI's interactive Platform App flow. Ask the user to enter its client secret only in the local CLI prompt; never request it in chat, write it to Hermes configuration, or commit it.
+- If an install, browser authorization, environment switch, or permission change needs approval, request that approval and resume the setup after it is granted. Do not replace the action with a command list.
+
+## Start each task
+
+1. Confirm the CLI and current actor. Probe with `command -v box` on POSIX shells or `Get-Command box -ErrorAction SilentlyContinue` in PowerShell. If `box` is on `PATH`, use it. If Hermes installed the CLI under its current home, use the shell-appropriate verified runner in [CLI guide](https://github.com/NousResearch/hermes-agent/blob/main/skills/productivity/box/references/cli-guide.md) in place of every leading `box`. Then run `box users:get me --json --fields id,name,login` with that runner.
+   If this succeeds, record the actor and continue. Do not ask about authentication again. Treat `folders:items 0` only as a listing of the actor's root; it is not proof that a shared file, folder, or Hub is inaccessible. For a known file or folder, verify its ID directly; for a Hub, use the Hubs discovery path in [Box Hubs](https://github.com/NousResearch/hermes-agent/blob/main/skills/productivity/box/references/hubs.md).
+2. If authentication is absent, ask to connect a Box account with OAuth, then ask whether Hermes and the authorization browser run on the same computer or on separate hosts. Read [OAuth setup](https://github.com/NousResearch/hermes-agent/blob/main/skills/productivity/box/references/oauth-setup.md).
+3. Read the relevant reference before operating. Use documented commands first; only run subcommand help when the request needs an option not covered by the reference or the installed CLI rejects the documented form.
+
+Examples labeled `bash` use POSIX continuation syntax. In PowerShell, run the Box command on one line or replace each trailing `\` with PowerShell's backtick continuation. Do not paste POSIX variable assignments into PowerShell.
+
+## Extend the CLI without pausing
+
+When the Box CLI lacks a dedicated subcommand, use `box request` for the matching REST endpoint and continue the ordinary operation. Do not ask the user to choose merely because the implementation uses REST; it is the same Box task and preserves the configured CLI identity. Read [REST API fallback](https://github.com/NousResearch/hermes-agent/blob/main/skills/productivity/box/references/rest-api.md) when the endpoint needs a request body or custom header.
+
+Ask before a delete, a collaboration/shared-link or permission change, an identity change, a broad or costly batch mutation, or when the target or scope is ambiguous. Otherwise perform the requested operation and verify it.

+
+## Content handling policy
+
+For semantic analysis of Box-hosted content, prefer Box AI: it preserves Box permissions, processes source files through Box's governed AI integration, keeps source-file bodies out of Hermes' coding-model context, and scales document work without downloading every file. Do not criticize or block another workflow; use it when the user explicitly chooses it.
+
+Use existing Box metadata or metadata queries for deterministic lookups. Otherwise use Box AI:
+
+- `ai:ask` for Q&A, summaries, and comparisons
+- `ai:extract-structured` for known fields or metadata templates
+- `ai:extract` for flexible key-value extraction
+- `ai:text-gen` for writing grounded in one Box file
+
+For Q&A over more than 25 files or a reusable curated knowledge base, prefer Box AI for Hubs. Discover an existing accessible Hub first; only create or populate one after the user approves the shared-resource change. If no Hub is available and the user does not want one created, narrow a one-off request with search or metadata. Do not use a Hub for metadata extraction or text generation. Read [Box Hubs](https://github.com/NousResearch/hermes-agent/blob/main/skills/productivity/box/references/hubs.md).
+
+When the user asks to extract metadata from a Box file, treat it as a request to persist the result unless they ask for a preview. Use structured extraction with inline fields when the desired schema is known and freeform extraction when the fields are exploratory. Reuse a compatible existing enterprise template when one represents every requested field. Otherwise store flat scalar results in the built-in `global.properties` metadata instance, or upload a JSON sidecar beside the source file when the result contains nested objects, tables, or values that must retain their types. Read every write back and compare it with the intended result. Never silently substitute a file description, attach a partial or unrelated template, truncate fields, or discard fields.
+
+Do not create or change metadata templates. Box does not permit creation of global templates, and enterprise-template administration is outside Hermes' normal OAuth content workflow. If the user needs reusable typed enterprise metadata and no compatible template exists, explain that a Box Admin or authorized Co-Admin must create it separately, leave existing structured metadata unchanged, and report the persisted `global.properties` instance or JSON sidecar instead. Read [Search and AI](https://github.com/NousResearch/hermes-agent/blob/main/skills/productivity/box/references/search-and-ai.md) for the complete extraction and writeback workflow.
+
+Before the first Box AI request, state that Box AI must be enabled, consumes AI units, and remains limited to the current actor's permissions; do not wait for acknowledgement. An AI response returned to Hermes can still contain sensitive information. Confirm only when a material batch's file scope or expected AI-unit use is ambiguous, or when the user has not explicitly requested that scale. See [Search and AI](https://github.com/NousResearch/hermes-agent/blob/main/skills/productivity/box/references/search-and-ai.md).
+
+## Operate safely
+
+- Prefer IDs to paths and verify the current actor before diagnosing a missing file.
+- Use `--json` and `--fields` to keep output small. For mutations, inventory first, confirm ambiguous or large scope, then read back the result.
+- Run ordered CLI mutations serially so progress and recovery are unambiguous. Use documented bulk input support or bounded SDK concurrency for scalable work.
+- Do not create a shared link merely to provide navigation. Shared links change access and require explicit confirmation.
+- Do not put secrets in chat, command output, source control, or logs.
+
+## Report results
+
+For every individually reported Box item, include its ID and a clickable navigation link:
+
+- File: `https://app.box.com/file/<FILE_ID>`
+- Folder: `https://app.box.com/folder/<FOLDER_ID>`
+- Hub: `https://app.box.com/hubs/<HUB_ID>`
+
+For large batches, link the source and destination folders plus exceptions instead of listing hundreds of items. A human may not be able to open content that is only visible to the connected Box account; state that clearly. Include the actor and verification performed in every write summary.
+
+## Verify
+
+After any write, fetch the file or folder with the same actor or list its parent and confirm the returned ID and name. For a metadata write, retrieve the metadata instance and compare every returned field with the intended value; an HTTP success alone is not verification. Report missing, normalized, or rejected values. For a disposable setup check, create a smoke folder, verify it, then delete it only if the user authorized cleanup.

+:::
+
+# draw-your-font
+
+Photo of handwritten letters in → installable font out. You do the seeing
+(find and label letters, judge quality); the CLI does all geometry (trace,
+metrics, font assembly). Never edit SVG paths or coordinates yourself.
+
+## Setup in Hermes (once per session)
+
+The CLI is the pinned npm package `draw-your-font@0.1.0` — run it via npx (Node ≥ 18 required, no global install needed):
+
+```bash
+npx -y draw-your-font@0.1.0 --help
+```
+
+Wherever the examples below show `$DYF`, use `npx -y draw-your-font@0.1.0`. Shell variables do not persist between tool calls, so paste the full command each time. Everything runs locally; the user's handwriting never leaves the machine.
+
+Photos arrive in Hermes either as a file path in the message or via the gateway image cache — use the actual file path with the CLI. When a photo lands in the conversation with no path, ask the user for the file (the CLI needs a real file, not your memory of the image).
+
+Do the visual steps (contact sheets, previews, glyph sheets) by loading the PNGs with `vision_analyze`.
+
+## Decide the flow
+
+- **User has no photo yet** → offer the template: print, write, photograph.
+- **User shares photo(s) of handwriting** → main flow below.
+- **User pasted an image but there is no file path** → you can see it, but the
+  CLI needs a file. Ask them to drag the image file into the terminal (that
+  inserts its path) or give the path directly. Do not proceed from memory.
+- **User wants changes to a font built this session** → Refine section.
+
+## Template flow (best quality)
+
+```bash
+$DYF template -o template.pdf --charset minimal   # or: spanish
+```
+
+Tell the user: print it, write one character per box with a dark pen
+(0.5 mm+), keep the letter sitting on the solid line, then photograph each
+page from above in good light and share the file paths. The grid prints in
+light grey and vanishes during processing - only their ink survives.
+
+## Main flow: photo(s) → font
+
+**1. Segment.** Works for template pages and freeform photos alike:
+
+```bash
+$DYF segment photo1.jpg photo2.jpg -d work
+```
+
+**2. Look, then label.** Load `work/contact-1.png` with `vision_analyze` (one per photo): every
+detected blob is numbered. This is the step where your eyes matter - check:
+
+- Did every written character get exactly one box? A letter drawn with
+  separate strokes may appear as two boxes (relabel handles it: give the main
+  box the character and mark the fragment `""`), and two touching letters may
+  share one box (ask the user to re-shoot just those, or accept the gap).
+- Junk boxes (shadows, ruled lines, smudges, page edges) → label them `""`.
+
+Then write `work/labels.json` mapping blob id → character, e.g.
+`{"0": "A", "1": "B", "7": "", "8": "a"}`:
+
+- Template page: order is the charset order printed on the template - verify
+  against the sheet instead of trusting it blindly. minimal order: A–Z, a–z,
+  0–9, then `.,;:!?'"-()@#&+/$`; spanish appends `ÑñÁÉÍÓÚáéíóúü¿¡`.
+- Freeform: identify each letter from the contact sheet. Uppercase vs
+  lowercase for shape-twins (S/s, O/o, C/c, X/x…) is decided by relative size
+  and position - compare against neighbors you're sure of.
+- The user told you what they wrote (e.g. "ABC then abc")? Trust it, map in
+  reading order (top row first, left to right), and verify visually.
+- Same letter appears twice → label the better-drawn one, `""` the other.
+
+**3. Build.**
+
+```bash
+$DYF build -d work --labels work/labels.json --name "Dan's Hand"
+```
+
+Name the font after the user (ask if unclear - one short question max).
+
+**4. Judge before delivering.** Load `work/preview.png` and `work/glyphs.png` with `vision_analyze`
+and critique like an art director:
+
+- Broken or blotchy letters (bad trace) → often a faint pen stroke; try
+  `--weight 1`, or ask for a re-shoot of just that letter.
+- Everything too thin/thick → rebuild with `--weight 1` / `--weight -1`.
+- Jagged edges → rebuild with `--smooth 1.5` (up to 2).
+- A letter placed wrong (e.g. a `g` not descending) → usually a mislabel;
+  fix labels.json and rebuild.
+- Filled-in bowls (b, o, g look solid): should never happen - if it does,
+  the crop is smudged; ask for a re-shoot.
+
+Rebuilds are cheap and safe to iterate. Fix what you can yourself first;
+only bother the user for re-shoots when the source ink is the problem.
+
+**5. Deliver.** The font lands at `<workdir>/<NameWithoutSpaces>.ttf` (the
+build output prints the exact path). Give that path and how to install:
+macOS - double-click → "Install Font"; Windows - right-click → "Install".
+Mention what's missing (the build prints uncovered letters) and offer,
+without pushing:
+
+- Web formats + CSS: rebuild with `--formats ttf,woff,woff2,css`.
+- A legibility read (below).
+- Their next photo to fill missing characters: re-run segment with ALL
+  photos (old and new) into a fresh workdir - `$DYF segment p1.jpg p2.jpg -d
+  work2` - then relabel from the new contact sheets (blob ids renumber; the
+  old labels.json does not carry over) and build from the new workdir.
+
+## Refine (conversational iteration)
+
+| User says | Do |
+|---|---|
+| "smoother / rounder" | `build … --smooth 1.5` (max 2) |
+| "thicker / bolder" | `build … --weight 1` (max 2) |
+| "thinner / lighter" | `build … --weight=-1` (negative needs the `=` form) |
+| "the g looks bad" | show them `work/crops/<id>.png` for that letter; offer re-shoot or smooth |
+| "wrong letter" / swap | edit labels.json, rebuild |
+| "give me woff2 / web" | `build … --formats ttf,woff,woff2,css` |
+| custom preview text | `$DYF preview -d work --text "…"` (after a build) |
+
+All refine commands rebuild from the stored crops - no re-photographing
+needed unless the ink itself is the problem.
+
+## Legibility report (offer after delivering)
+
+```bash
+$DYF preview -d work --text "minimum mill rn m cl d I l 1 O 0 quick brown fox" -o work/legibility.png
+```
+
+Read it and give an honest, kind read: a score out of 10 for body-text use,
+the 2–3 letter pairs most likely to confuse (rn→m, cl→d, I/l/1, O/0), and one
+or two concrete fixes (rewrite those letters larger, more spacing). Note that
+display use (headings, notes) is more forgiving than paragraphs. Never gate
+delivery on this - it's advice, not a blocker.
+
+## Troubleshooting
+
+Segmentation found far too many / too few blobs, grey guide lines surviving,
+shadow blobs, faint ballpoint strokes → see
+`references/troubleshooting.md`.

+:::
+
+# Simple English: Write Like an Aerospace Manual
+
+Write technical text with the rules of ASD-STE100 Simplified Technical English. STE is the controlled language that aerospace and defense manufacturers use for maintenance documentation. The rules exist so that a tired reader who is not a native English speaker cannot misread an instruction. They remove the usual signs of AI-generated text as a side effect: long sentences, synonym rotation, hedges, filler, and decorative clauses.
+
+Write for that tired reader. Each sentence must survive one read.
+
+## How to use it in Hermes
+
+The text usually arrives one of three ways:
+
+1. **Inline.** The user pastes the text into the message. Rewrite it in place and reply with the result.
+2. **File.** The user points at a file (README, runbook, docs page). Use `read_file` to load it, then `patch` for targeted section rewrites or `write_file` for a full rewrite. Never touch code blocks, identifiers, or quoted errors (see Untouchables).
+3. **Check mode.** The user asks you to audit text for STE compliance instead of rewriting it. Report each violation as rule number + offending text + compliant rewrite, using `references/checklist.md`.
+
+This skill differs from `humanizer`: humanizer restores natural human voice; simple-english enforces a controlled language for technical instructions. For docs, runbooks, and error messages use this skill. For blog posts, essays, and personal writing use humanizer. Do not apply both to the same text.
+
+## Your Task
+
+When asked to write or rewrite technical text:
+
+1. **Select the mode** (pragmatic or strict, below).
+2. **Classify each passage** as procedural or descriptive. Every other rule depends on this.
+3. **Correct your vocabulary before drafting.** In strict mode, use `make sure that` for the check/verify/confirm/ensure concept — the dictionary rejects all four as verbs. In pragmatic mode, pick one and keep it. Pick ONE noun for config/settings (all are valid technical nouns — pick one and keep it). Use no other word for these concepts in the whole document.
+4. **Apply the rules** from the catalog below.
+5. **Do the self-check** before you deliver. This step is not optional.
+6. **Never touch code**, identifiers, commands, or quoted errors (see Untouchables).
+
+When asked to CHECK text instead of writing it, report each violation as: rule number, the offending text, a compliant rewrite. Cite only rule numbers that exist in this file. Do not cite rule numbers from memory: the numbering is unintuitive and models invent it (tested — an agent without this file cited "Rule 3.1: short sentences"; the real Rule 3.1 is about verb forms).
+
+## Two Modes
+
+| Mode | When | What you apply |
+|---|---|---|
+| **Pragmatic** (default) | Docs, READMEs, error messages — the user wants clear text | All structural rules. Domain words stay ("idempotent", "webhook"). |
+| **Strict** | The user names STE, ASD-STE100, or compliance | Structural rules + full vocabulary discipline, and tell the user that full compliance needs the official dictionary (free at asd-ste100.org). |
+
+## Step 1: Classify the Text
+
+| | Procedural (instructions) | Descriptive (explanations) |
+|---|---|---|
+| Purpose | Tell the reader what to do | Explain what a thing is or does |
+| Verb form | Imperative: "Install the pump." | Simple present/past/future |
+| Sentence limit | **20 words** (Rule 5.1) | **25 words** (Rule 6.3) |
+| Unit rule | One instruction per sentence (5.2) | One topic per paragraph (6.5), max six sentences per paragraph (6.6) |
+
+Do not mix the two in one passage. A "Getting started" section is procedural. An "Architecture" section is descriptive. A note inside a procedure is descriptive (25-word limit, no imperative).
+
+## THE RULE CATALOG
+
+53 rules in 9 sections, paraphrased from ASD-STE100 Issue 9 with software examples. The official wording is in the free standard at asd-ste100.org.
+
+### Section 1 — Words (Rules 1.1-1.14)
+
+| Rule | Instruction |
+|---|---|
+| 1.1 | Use only approved words, technical nouns, or technical verbs. |
+| 1.2 | Use an approved word only as its listed part of speech. |
+| 1.3 | Use an approved word only with its approved meaning. |
+| 1.4 | Use only the approved forms of verbs and adjectives. |
+| 1.5 | You can use domain words as technical nouns ("webhook", "commit", "endpoint"). |
+| 1.6 | Use an unapproved word only when it is a technical noun or part of one. |
+| 1.7 | Do not use technical nouns as verbs. |
+| 1.8 | Use the technical nouns of your project or industry. |
+| 1.9 | When you pick a technical noun, pick a short and clear one. |
+| 1.10 | No regional, slang, or jargon words as technical nouns. |
+| 1.11 | One item, one name. Do not call it "config" here and "settings" there. |
+| 1.12 | You can use domain verbs as technical verbs ("deploy", "compile", "merge"). |
+| 1.13 | Do not use technical verbs as nouns. |
+| 1.14 | Use American English spelling. |
+
+In pragmatic mode, rules 1.5, 1.8, and 1.12 do the heavy lifting: your domain vocabulary is legal. The ones agents break are 1.7, 1.11, and 1.13.
+
+**Before:** You can webhook the event, then do a deploy.
+**After:** Send the event to the webhook. Then deploy the service.
+
+### Section 2 — Multi-word nouns (Rules 2.1-2.2)
+
+| Rule | Instruction |
+|---|---|
+| 2.1 | Write multi-word nouns of three words or fewer. |
+| 2.2 | When a technical noun needs more than three words, write it in full once, then give a short form or hyphenate the units. |
+
+Break long noun chains with prepositions (of, on, in, for):
+
+**Before:** the connection pool timeout configuration value
+**After:** the timeout value for the connection pool
+
+### Section 3 — Verbs (Rules 3.1-3.7)
+
+| Rule | Instruction |
+|---|---|
+| 3.1 | Use only the verb forms that the dictionary gives. |
+| 3.2 | Use only: infinitive, imperative, simple present, simple past, simple future, past participle as adjective. |
+| 3.3 | Use the past participle only as an adjective ("the cached response"). |
+| 3.4 | No auxiliary verbs for complex constructions. No present perfect, no "is to be installed". |
+| 3.5 | Use an "-ing" form only as a technical noun or inside one ("logging", "the mounting bracket") — never as a verb. |
+| 3.6 | Active voice. In descriptive text, passive is legal only when the agent is unknown. |
+| 3.7 | Describe an action with a verb, not a noun ("compress the file", not "perform compression of the file"). |
+
+**Approved modals: can, will, must. Banned: should, would, may, might, could.**
+The standard rejects "could" even for possibility: write "an explosion can occur", never "could occur". For "should": a requirement becomes "must"; a suggestion is stated as fact or deleted. This matters double for agent instructions — models read "should" as optional.
+
+**Before:** The migration has completed and the table is being rebuilt.
+**After:** The migration is complete. The database rebuilds the table.
+
+**Before:** The flag can be set in the config file, making restarts unnecessary.
+**After:** You can set the flag in the config file. Then a restart is not necessary.
+
+**Before:** The temperature must be adjusted.
+**After:** Adjust the temperature.
+
+### Section 4 — Sentences (Rules 4.1-4.5)
+
+| Rule | Instruction |
+|---|---|
+| 4.1 | Write short and clear sentences. |
+| 4.2 | Do not omit words or use contractions to shorten sentences. Keep articles, keep "that". |
+| 4.3 | Use a vertical list for complex text. |
+| 4.4 | Use connecting words between sentences on related topics ("Then", "As a result"). |
+| 4.5 | Put an article (the, a, an) or a demonstrative adjective (this, these) before nouns where applicable. |
+
+Rule 4.2 is the anti-terseness rule. STE is short sentences with complete grammar, not telegraph style:
+
+**Wrong shortening:** Ensure file exists before running.
+**STE:** Make sure that the file exists before you run the command.
+
+### Section 5 — Procedural writing (Rules 5.1-5.5)
+
+| Rule | Instruction |
+|---|---|
+| 5.1 | Maximum 20 words per sentence. Warnings and cautions included. |
+| 5.2 | One instruction per sentence, unless two actions happen at the same time. |
+| 5.3 | Write instructions in the imperative: "Run the migration." |
+| 5.4 | Put a required condition before the command, divided by a comma: "If the build fails, read the log." |
+| 5.5 | Notes give information, never instructions. Notes get the 25-word limit. |
+
+**Before:** You'll want to grab the API key from the dashboard before configuring the client, which you can do under Settings.
+**After:** Get the API key from the dashboard, under Settings. Then configure the client with this key.
+
+### Section 6 — Descriptive writing (Rules 6.1-6.6)
+
+| Rule | Instruction |
+|---|---|
+| 6.1 | Give information gradually: one new fact per sentence. |
+| 6.2 | Use key words and phrases to give the text a logical structure. |
+| 6.3 | Maximum 25 words per sentence. |
+| 6.4 | Group related information in paragraphs. |
+| 6.5 | One topic per paragraph. |
+| 6.6 | Maximum six sentences per paragraph. |
+
+No imperative in descriptive text. Descriptions explain; procedures instruct.
+
+### Section 7 — Safety instructions (Rules 7.1-7.3)
+
+| Rule | Instruction |
+|---|---|
+| 7.1 | Use a word that shows the risk level ("WARNING" = injury, "CAUTION" = damage). |
+| 7.2 | Start with a clear command or condition. |
+| 7.3 | Then give the risk or the possible result. |
+
+Never bury the instruction after the explanation. The pattern transfers directly to destructive CLI flags, irreversible migrations, and dangerous API options.
+
+**Before:** Note that data loss may occur in some circumstances if the destructive flag happens to be enabled when running against production.
+**After:** CAUTION: Do not use the `--force` flag against production. The flag deletes rows that do not match the source.
+
+### Section 8 — Punctuation and word count (Rules 8.1-8.7)
+
+| Rule | Instruction |
+|---|---|
+| 8.1 | All standard punctuation is legal except the semicolon. Write two sentences instead. |
+| 8.2 | Use hyphens to connect words that act as one unit. |
+| 8.3 | Parentheses are legal for references, item numbers, abbreviations, plural forms, explanations, alternatives. |
+| 8.4 | In a vertical list, the lead-in colon ends a sentence for word count. |
+| 8.5 | Text inside parentheses counts as one word. |
+| 8.6 | Count as one word each: numbers, numbers with units, abbreviations, alphanumeric identifiers, quoted text, titles, labels, proper nouns. |
+| 8.7 | A hyphenated word counts as one word. |
+
+Rule 8.6 matters for software text: `sqlpipe run --config sqlpipe.yaml` in backticks is quoted text and counts as one word. Long identifiers do not blow your sentence budget.
+
+### Section 9 — Writing practices (Rules 9.1-9.4, GR-1 to GR-8)
+
+| Rule | Instruction |
+|---|---|
+| 9.1 | When a word-for-word replacement does not work, restructure the sentence. |
+| 9.2 | Use each approved word correctly: approved meaning, approved part of speech. |
+| 9.3 | Do not build phrasal verbs ("go down" → "decrease", "set up" → "install" or "configure"). |
+| 9.4 | Keep one consistent style and terminology through the whole document. |
+
+General recommendations GR-1 to GR-8: keep the conjunction "that", be careful with "with", give pronouns clear referents, prefer "this + noun" over bare "this", avoid false friends, avoid Latin abbreviations, use inclusive language, and use the possessive apostrophe form only when you are sure it is correct (GR-8: if unsure, do not use it — non-native readers find it hard).
+
+GR-6 for software docs: "e.g." → "for example", "i.e." → "that is", and delete "etc." — name the items or write "and more".
+
+## VOCABULARY DISCIPLINE
+
+The official dictionary (~900 approved words, ~1,200 banned words with alternatives) is copyrighted by ASD and is not reproduced here. Its mechanics apply without it: **one word, one meaning, one part of speech.**
+
+Known part-of-speech rulings, useful as patterns:
+
+| Word | Ruling |
+|---|---|
+| test, check, work | Noun only. "Do a test", not "test the pump". "Check that X" becomes "make sure that X". |
+| oil | Technical noun (TN) only. For the verb, the dictionary gives "lubricate": "Lubricate the linkage with oil." |
+| help | Verb only. For the noun, the dictionary gives "aid": "with the aid of". |
+| fall (noun) | Rejected. Use "decrease" for a reduction in value. Use FALL (verb) only for physical movement downward by gravity: "Make sure that the tools do not fall into the engine." |
+| follow | "To come after" only, never "obey". Write "obey the instructions". |
+| above, below | Physical positions only. For limits write "more than", "less than". |
+
+### The modal ladder
+
+| You wrote | STE writes |
+|---|---|
+| should (requirement) | must |
+| should (recommendation) | Delete it, or state it as fact: "X is better because Y." |
+| may / might / could (possibility) | can |
+| may (permission) | can |
+| would (hypothetical) | Restructure: "If X occurs, Y occurs." |
+
+### Slop-to-simple substitutions
+
+This table is ours, not the ASD dictionary. It maps the words AI-generated docs overuse to plain replacements. If the word carries no fact, delete it instead of replacing it.
+
+| Slop | Write instead |
+|---|---|
+| leverage, utilize | use |
+| in order to | to |
+| prior to | before |
+| ensure | make sure that |
+| it is worth noting that | (delete) |
+| it's important to, crucially | (delete — state the fact) |
+| simply, just, easily, seamlessly, effortlessly | (delete) |
+| robust, powerful, comprehensive, performant | (delete, or give the measurable property) |
+| functionality | function, feature |
+| enables you to, allows you to | you can |
+| is designed to, aims to | (delete — say what it does) |
+| facilitate | help, make possible |
+| dive into, delve into | read, examine |
+| when it comes to | for |
+| in the event that | if |
+| due to the fact that | because |
+| as needed, as necessary | (state the condition) |
+| and/or | Pick one, or write "X, or Y, or both" |
+| e.g. / i.e. / etc. | for example / that is / (name the items) |
+| gracefully handles | (say what it does: "retries three times, then stops") |
+| out of the box | by default |
+| under the hood | internally |
+| blazingly fast, state-of-the-art | fast (give the number) / (delete) |
+| streamline | make simpler, make faster |
+| plethora, myriad | many |
+| addresses the issue, tackles | corrects the fault, removes the error |
+
+### Consistency pass
+
+Collapse synonym rotations to one term each (Rules 1.11, 9.4). The two lists below work differently.
+
+**Technical nouns — not in the dictionary. Pick one and keep it consistent (both modes):**
+
+- config / configuration / settings / options → pick one
+
+**Dictionary rulings — the standard has already chosen. Use the approved word (strict mode); pick one and keep it consistent (pragmatic mode):**
+
+| You wrote | Dictionary status | Use instead |
+|---|---|---|
+| check (verb) / verify / confirm / ensure | All rejected as verbs | `make sure that` (strict); pick one (pragmatic) |
+| validate | Not in dictionary | Use as technical verb (Rule 1.12), or replace with `make sure that` |
+| delete / drop (verb) / destroy | All rejected | `erase` (data), `remove` (physical); avoid `drop` and `destroy` |
+| remove | Approved verb | Keep it |
+| run / execute | Both rejected | `operate` for run, `do` for execute (strict); pick one (pragmatic) |
+| invoke / launch | Not in dictionary | Use as technical verbs (Rule 1.12) |
+| display (verb) / render / present (verb) | All rejected | `show` (approved verb) |
+| issue | Not in dictionary | Use as technical noun, or replace with `problem` (approved) |
+| failure | Rejected in general use; approved as TN for performance loss | Use only when it means a performance error: "a failure of the pump" |
+| error | Approved noun | Keep it |
+| problem | Approved noun | Keep it |
+
+## Untouchables
+
+These are technical names (Rules 1.5, 8.6). Leave them exact, even when they break vocabulary rules:
+
+- Code blocks, inline code, identifiers, CLI commands, flags, file paths
+- Quoted error messages and log lines
+- Product names, API endpoint names, config keys
+- Numbers with units — each counts as one word in the sentence limit
+
+## Beyond Documentation
+
+Same rules, different targets. Full adaptations in `references/use-cases.md`:
+
+- **Error messages**: state what happened (simple past), the cause if known, then the fix as an imperative. No "Oops", no "Please ensure", no apology filler.
+- **Runbooks**: STE's home turf. Imperative steps, conditions first, warnings before the step.
+- **Incident reports**: simple past only. "We have identified an issue that may have impacted" becomes "Between 14:02 and 14:31 UTC, 12% of requests failed."
+- **Release notes**: breaking changes follow the warning pattern — command first, risk second.
+- **Agent instructions (prompts, AGENTS.md)**: a system prompt is a procedure for a reader that cannot ask questions. One instruction per sentence, no "should", condition first.
+- **Translation prep**: STE's original job. One meaning per word plus complete grammar removes most translation ambiguity.
+
+## Self-Check Before You Deliver
+
+This step is not optional. Run these four checks on your draft:
+
+1. Count words in your three longest sentences. Over the 20/25 limit → split them.
+2. Search your draft for: `'ll`, `'re`, `'s` (contraction), `has been`, `have been`, `should`, `-ing` verbs after a comma, semicolons.
+3. Search for every `if` and `when`. Each one stands at the START of its sentence, before the command. "Increase the timeout if the network is slow" → "If the network is slow, increase the timeout."
+4. Search for the verbs you did NOT pick in Your Task step 3 (the check/verify/confirm set). Replace every hit with your chosen verb.
+
+Fix what you find, then deliver. For a full audit, run `references/checklist.md`.
+
+## Full Example
+
+**Before (real unedited AI output):**
+
+> **Connection timeouts.** If sqlpipe hangs or fails with `dial tcp: i/o timeout`, check that the host running sqlpipe can reach the Postgres port (usually 5432) — this is often a security group or firewall rule blocking the connection. If you're connecting to a managed database (RDS, Cloud SQL, etc.), confirm the instance allows connections from sqlpipe's IP. You can also try increasing `source.connect_timeout_seconds` in your config, since a slow network path can trip the default timeout even when the connection eventually succeeds.
+
+**After (classified procedural, verb = "make sure", conditions first, one instruction per sentence):**
+
+> **Connection timeouts.** sqlpipe stops with `dial tcp: i/o timeout` when it cannot reach the Postgres port (5432 by default).
+>
+> 1. Make sure that the host that runs sqlpipe can reach the Postgres port. A firewall or security group usually blocks it.
+> 2. If the database is managed (RDS, Cloud SQL), make sure that the instance accepts connections from the IP of sqlpipe.
+> 3. If the network is slow, increase `source.connect_timeout_seconds` in the configuration.
+
+What changed: 40-word sentences split under 20; "you're" expanded; "check/confirm" collapsed to "make sure that"; every condition moved before its command; "etc." removed; code and error strings untouched.
+
+## Limits
+
+STE is for technical facts and instructions. Do not apply it to marketing copy, blog voice, or brand writing — it deletes persuasion by design. When a user asks for STE on marketing text, say so and offer it for the docs instead.
