Covers the precise pinned-session resolver added in PR #88690: request
param shape, the preferred_session response field, hidden-row and
compression-lineage resolution, and older-gateway behavior.
An inline ::preview widget could render and be clicked, but the click went
nowhere: the sandbox has no channel to the agent, so an interactive chart
was a dead end. Now the frame injects a second script beside the measurer
that gives the page one voice:
window.hermes.send('get-price eth')
<button data-hermes-send="get-price eth">ETH</button> (zero-script form)
The prompt rides postMessage up tagged with the mount token, then goes
through the composer's own send path (requestComposerSubmit -> prompt.submit)
flagged display_kind=hidden — the same row-typing auto-continue and internal
notifications already use. The agent wakes and takes a real turn; the
durable row persists (context, resume, DB audit); but NO bubble renders,
live or on reload. The user clicks ETH and the chart just changes — the
off-screen loop is click -> hidden turn -> agent rewrites the widget file ->
frame hot-swaps.
Trust boundary matches size reports and is tighter where it matters: mount
token required (frames can't forge each other's intents), string-only,
trimmed, capped at 500 chars, throttled to one intent per second per frame.
The gateway whitelists display_kind to "hidden" — the RPC can't mint
arbitrary row types — and the flag threads through both turn paths (inline
and compute-host isolation) so isolated sessions don't resurrect bubbles on
resume.
The desktop platform hint teaches the model to wire interactive widgets
with data-hermes-send and to answer clicks by updating the widget's file
rather than with prose; the SDK doc documents the contract.
The SDK doc still described the v1 frame (fixed height attribute, rail card
under the frame) — chrome that no longer exists. And plugin_storage's usage
example used `with plugin_db(...)`, which reads as auto-close but sqlite3's
context manager only scopes transactions; the example now closes explicitly.
The first cut of the core ::preview consumer rendered the classic
preview-attachment card — a button into the right rail we already had, which
made the directive indistinguishable from an ordinary preview link. Now the
directive shows the thing itself: the workspace HTML file renders in a
sandboxed srcdoc iframe inline in the assistant message (opaque origin,
allow-scripts only — no reach into the app, its storage, or the bridge),
with an optional height attribute clamped to 120-1200px and the classic
card kept below as the rail escape hatch.
The frame waits for turn settle before reading the file (mid-stream it is
often mid-write), resolves relative paths against the session's own cwd,
and falls back to the plain card for non-HTML targets and remote gateways
(no local file door there).
The transcript becomes a contribution area (transcript.directives). A plugin
registers a named directive and the model addresses it by emitting
::name{key="value"} as its own paragraph; that leaf renders as the plugin's
component, wrapped in the contribution error boundary. Unclaimed or malformed
directives stay plain prose, so nothing changes for text that merely looks
like a directive (std::vector) or for users with the plugin disabled.
Core ships ::preview{file="..."} as the reference consumer (the existing
preview-attachment card), the desktop platform hint teaches the model the
syntax, and the SDK exports the area + types so runtime plugin.js files get
the surface through the normal plugins API.
Independent second-pass review found three gaps:
- focusedUsage is null | UsageStats, not Partial — ClientSessionState.usage
is the full type (app/types.ts) and its only write site seeds the four
required fields before merging (gateway-event.ts). The earlier Partial
annotation traced the wrong type (SessionRuntimeInfo, an RPC payload).
Comment now names the genuinely optional fields instead.
- The tile-focus contract test never seeded $sessionTiles/$sessionStates,
so it proved focusedStoredSessionId follows a tile but could not
distinguish focusedSessionId/focusedUsage working from broken. Seed a
bound runtime with distinct usage and assert both readout atoms move.
- The two public host.state references (website docs + bundled skill
reference) enumerated the old six atoms; plugin authors would never
discover the new ones. Both lists updated.
tsc/eslint/vitest green (4/4).
Gate composer submit and plugin host busy on the target session slice, not a leftover foreground busyRef. Staff can keep typing while a worker session is running.
Includes the follow-up test that submit uses the target session busy flag.
Follow-up to the salvaged #87558 commit: the PR's docs promised the flags
follow "the focused chat", but PRIMARY_SESSION_VIEW is the primary
workspace tab only — a focused session TILE would read the wrong chat.
Wire host.state.busy / host.state.awaitingResponse through the focused
slice ($focusedStoredSessionId / $focusedSessionState), same semantics
as the statusbar busy pulse, with the primary view (and its draft
fallback) while the workspace holds focus.
Adds a tile-focus vitest case and corrects the docs wording.
Plugins can now read host.state.busy and host.state.awaitingResponse
for the focused chat. These follow the same session slice the chat pane
uses, so a draft falls back to the global flags and a background turn
does not leak.
Closing a pane contributed by a plugin used to disable the entire plugin,
unloading every one of its contributions. For a plugin that owns several
independent panes (e.g. Bot Mode's Cronjobs pane alongside its Bots roster
and composer middleware), closing one pane silently killed the rest.
Now: closing one pane of a multi-pane plugin dismisses only that pane; the
plugin stays enabled and its other panes/commands/middleware keep working.
Reset layout restores dismissed contributed panes. A single-pane plugin
keeps the existing symmetric behavior (Close disables the plugin, with
Settings -> Plugins as the recovery path).
Adds regression coverage for both cases.
Desktop plugins reach the backend exclusively through the generic ws
JSON-RPC door (host.request), but profile enumeration/creation only
existed on the dashboard REST router, which plugins cannot reach — so
anything 'one chat per agent profile'-shaped (bot rosters, profile
pickers, team panes) was impossible to build as a plugin.
- tui_gateway/methods_profiles.py: new @method handlers
* profiles.list — profiles + optional last_session preview per profile
(mirrors session.list's kanban/tool deny-list; best-effort per-profile
state.db probe degrades to null instead of failing the call)
* profiles.create — ws twin of POST /api/profiles (clone_from/clone_all/
no_skills/description), plus optional SOUL.md content and a best-effort
model+provider pin; mirrors the CLI flow (seed skills, safe alias)
Both run on the RPC pool, not the WS reader thread (list_profiles walks
skill trees; create copies bundles).
- SDK: host.openSession(id, { profile, intent }) — open a stored session
the way core surfaces do, soft-swapping to the owning profile's backend
first (ensureGatewayProfile), and host.newChat(profile) — fresh draft in
a named profile (same door as the sidebar's per-profile '+').
- Docs: desktop-plugin-sdk.md gains both surfaces.
First consumer: a Grok Bot-style 'Bots' roster plugin (one persistent
chat per agent profile with a New Agent dialog) built on exactly these
four doors.
Fold ctx.notifyNative into a ctx.os namespace so every way a plugin
reaches outside the app window lives behind one attributed door instead
of accreting one top-level ctx method per capability:
- ctx.os.notify — the native-notification door from the previous commit,
unchanged semantics (plugin kind pref, away-gating, per-plugin throttle).
- ctx.os.openExternal / ctx.os.revealPath / ctx.os.writeClipboard — the
existing window.hermesDesktop bridge capabilities, now sanctioned and
result-shaped: each resolves false (never throws) when the bridge or
member is missing, so a plugin branches on the result instead of
sniffing the preload surface or crashing on an older shell.
No new Electron surface: everything routes through bridge members the
app already ships; the notification path keeps every existing gate.
Desktop plugins can toast in-app (host.notify) but have no sanctioned way to
reach the OS notification pipeline the app's own approval/turn alerts use, so
a plugin surfacing a genuinely notable background event (e.g. a discovery
plugin finding a match) stays invisible once the user steps away from Hermes.
Add a curated per-plugin door instead of exporting the raw dispatcher:
- ctx.notifyNative({ title, body?, silent? }) on PluginContext — attributed
to the plugin id, routed through dispatchNativeNotification so every
existing gate applies (master + per-kind prefs, post-connect baseline,
away-from-app gating, throttle).
- New 'plugin' native-notification kind with its own Settings ▸ Notifications
toggle (default on), so users silence plugins without losing app alerts.
- New optional `tag` discriminator on the notify payload keys the renderer
throttle and main-process cross-window dedupe per plugin, so two plugins
can't collapse each other's session-less notifications.
Consumer: the Index Network desktop plugin wants background opportunity
alerts; anything in ~/.hermes/desktop-plugins gets the same door.
Add an end-to-end developer guide for extending the native Hermes Desktop
app introduced in #60638: the HermesPlugin contract, PluginContext, every
contribution area (panes, routes, sidebar nav, status/title bar, palette,
keybinds, themes, composer, mount-scoped Contribute), the host API, the
React Query + nanostores data layer, the UI kit + theme variables, the
scoped ctx.rest/ctx.socket backend (plugin_api.py under /api/plugins/<id>)
and its separate enable gate, Settings/defaultEnabled/storage, bundled
plugins, the security model, pitfalls, and a full reference.
- Register the page in the sidebar under Extending -> Plugins.
- Disambiguate from the unrelated web-dashboard plugin SDK from both
directions, and add a map-table row + a desktop user-guide pointer.
- Fill the gaps in the agent-facing hermes-desktop-plugins skill
(ctx.rest/socket + backend, React Query, defaultEnabled, Contribute)
and point it at the new reference so agents know the SDK when writing
addons.
