On hosted deployments a scheduled fire that cannot be forwarded to the
gateway api_server (dead 8642 listener, gateway down) was invisible
outside gui.log: no execution row is created because the claim never
happens, so `cronjob list` showed a healthy job that silently missed
days of scheduled runs (4 consecutive nightly misses in the field,
diagnosed only by log grep).
Changes:
- cron/jobs.py: note_fire_forward_failure() durably stamps
last_fire_error ({at, detail}) on the job record; mark_job_run clears
it on the next successful run so it always describes current
auto-fire health (mirrors preflight_alerted/drift_alerted).
- hermes_cli/web_routers/cron.py: the dashboard fire webhook stamps the
job on the gateway-unreachable path, best-effort (never disturbs the
503/Retry-After retry contract or the OOF-266 intentional-stop drop).
- tools/cronjob_tools.py: _format_job carries last_fire_error so the
agent-facing cronjob list surfaces it.
- hermes_cli/cron.py: `hermes cron list` prints a red
"Missed scheduled fire" line.
- web/: dashboard CronPage renders the miss; api.ts type updated.
- gateway/run.py: one-time startup warning when an external cron
provider is active but the api_server adapter is not running (the
fire path is dead-on-arrival; most common cause is API_SERVER_KEY
missing from an unsupervised gateway relaunch).
- website/docs: cron doc section on missed fires.
Review fold on the #88113 follow-up. The new guards asserted implementation
details that a strictly-better future change would break, and the second
producer of the payload schema had no coverage at all.
- The distinguishability test asserted the failure payload was byte-identical
to the genuinely-clean one (`for key in commits/dirty/pruned: assertEqual`).
That freezes the AMBIGUITY as a required property: emitting `commits: None`
for "unknown" would improve exactly what #88113 is about and fail the test.
Now asserts what the parent actually depends on -- both keep the worktree,
and only the flag separates them.
- `assertNotIn("inspection_failed", ok_payload)` pinned key ABSENCE on the
happy path, forbidding an always-present-but-False flag (a legitimately
better JSON contract: stable key set for serializers). Now
`assertFalse(...get("inspection_failed", False))` -- same coverage, tolerant
of that refactor.
- `assertIn("UNKNOWN", note)` coupled tests to one word of English prose, and
was not even a cross-producer contract: delegate_tool's note said "state
unknown" (lowercase), so a copy-edit broke the implied convention. Tests now
assert the note names the worktree AND branch -- the actionable part for a
human -- and both producers' notes were aligned to read as one contract.
- The raises test never proved its patched seam ran (a future short-circuit
before any git call would keep it green while proving nothing). Now checks
`call_count` and mirrors the branch-survival + note-names-path legs its
sibling had.
- NEW `WorktreePayloadSchemaTests`: commit 2's whole point is the schema the
parent reads, but delegate_tool's fallback -- the second producer -- was
verified only by reading. It now AST-parses the real fallback dict literal
and compares against live `finalize_subagent_worktree()` output, so the two
producers cannot drift and the pre-fix leak (repo_root/base_commit, missing
commits/dirty/pruned) cannot come back.
- Docs/docstring drift: the flag has a second trigger (finalization itself
raising, handled in delegate_tool), and the module docstring listed
`inspection_failed` without `note`. Both corrected.
- Extracted the duplicated 5-line "corrupt the index" setup into
`_break_git_index()` beside the file's other module-level helpers.
Validation: 19/19 tests/tools/test_subagent_worktree.py; ruff clean. New
schema guard mutation-checked -- reverting delegate_tool's fallback to the
pre-fix `dict(_worktree_info)` shape fails it. Restores checksum-verified.
The preserved worktree is invisible to the only consumer that can act on it.
Completes the #88113 fix. That change correctly stops the destructive prune
when a git probe fails, but still returns commits=0 / dirty=False -- values
that were never measured. Those are the defaults the prune used to delete on,
so the failure payload is byte-identical to "inspected fine, child left
nothing":
inspection FAILED, uncommitted work kept -> {commits: 0, dirty: False, pruned: False}
inspected OK, child produced nothing -> {commits: 0, dirty: False, pruned: False}
The only failure signal was a logger.warning, and the sole consumer of this
payload is the parent agent reading the serialized delegate_task entry -- it
cannot read logs (no in-repo code reads the key back). So the parent's rational
reading of the failure case is "the child produced no work", which is the exact
wrong conclusion: a worktree possibly full of uncommitted work is preserved and
then never looked at. The data survives but nobody is told to recover it.
Changes:
- subagent_worktree: one _unproven() helper stamps inspection_failed + a note
naming the worktree/branch, warns, and returns the payload. Both unproven
exits route through it, so they cannot drift apart again.
- subagent_worktree: the pre-existing exception path (timeout, OSError, a
non-numeric rev-list stdout) produced the same unproven payload but logged at
DEBUG -- effectively silent. It now takes the same flagged path as a non-zero
exit; identical outcomes get identical reporting.
- delegate_tool: the caller's finalize-raised fallback assigned the
creation-side metadata dict (path/branch/repo_root/base_commit) -- a disjoint
schema missing commits/dirty/pruned. It now emits the same flagged shape, and
logs at WARNING.
- Docs + docstring + module contract now state that pruning requires
affirmative proof, so a future cleanup doesn't "fix" the preserved worktree
by restoring the unconditional prune and reintroducing this P1.
Purely additive: the happy-path payload shape is unchanged, so no existing
reader can break.
Validation:
- 18/18 tests/tools/test_subagent_worktree.py; 127 passed across the delegation
suites (test_delegate, batch_validation, control_actions, timeout_diagnostic).
- 3 new guards mutation-checked: neutering the flag fails all three; reverting
the production file to pre-fix main fails all three. Restores checksum-verified.
- E2E on real git: inspection-failure now returns inspection_failed=true with
work intact on disk; proven-clean still prunes (pruned=true).
Healthy IPv4-first connect is the new default path, so two transports
were warning on every successful initialize. Keep warning only when a
literal actually failed first. Also restates the transport docstring
and docs to match IPv4-first, hostname last.
A blackholed IPv6 path to api.telegram.org never errors, so
_await_with_thread_deadline never fires and connect hangs at
"attempt 1/8". Known A-record IPs connect over IPv4 immediately.
DoH timeout now fail-opens to the seed IPv4 list instead of the
hostname. Hostname stays last for IPv6-only hosts.
Closes#87015
Follow-ups on top of the salvaged CommandCode provider plugin (PR #32909):
- hermes_cli/config_defaults.py: COMMANDCODE_API_KEY setup-wizard entry
- hermes_cli/doctor.py: add key to the doctor env-var scan list
(health check comes free via the pluggable-profile loop)
- hermes_cli/dump.py: include commandcode in debug-dump api_keys
- docs: provider table row, fallback-provider table + supported lists
- tests: doctor dedicated-skip test now uses exact-name checks so
Bearer-authed Anthropic-COMPATIBLE gateways (CommandCode (Anthropic))
are allowed in the generic loop while native anthropic stays skipped
E2E verified with real imports: profile registration, aliases,
PROVIDER_REGISTRY auto-extension, bearer-auth host match
(positive + negative), live /models fetch (55 models).
Post-merge docs sweep for the Aug 16 scout slate. Two pages:
- mcp.md: tool-result sanitization section — invisible Unicode TAG chars
(U+E0000-E007F) stripped from results/resources/descriptions (#80689);
vendor _meta surfaced to the model minus protocol-reserved
modelcontextprotocol/mcp prefixes (#80712)
- tools.md: tool result annotations section — signal-death exit notes
(subprocess -signum definite, shell 128+signum hedged) (#78074); UTF-16
read_file transcoding with disclosure hint and 10MB cap (#80717)
Security-policy docs (approvals/allowlist) intentionally untouched.
Fold the list/mapping parser INSIDE the existing string-typed-value coercion guard (the `not isinstance(_default_value_for_key(key), str)` block from e4ea0a0ed) instead of running it unconditionally, so a genuinely string-typed setting whose value merely starts with '[' or '{' is left untouched while non-string keys get JSON/YAML flow literals parsed to real lists/dicts.
Update website/docs/user-guide/configuring-models.md: the `config set only writes scalar values` note is no longer accurate; document the list/mapping support with a quoted example.
Fixes#40545#50168
paperclip#10978 made destructive replacement an explicit caller choice
in their skill-sync and package-import paths: a rerun must never remove
operator edits by default. Our hub-skill updater had the same hazard --
'hermes skills update' calls do_install(force=True), which rmtree-replaces
the skill directory even when the user edited it after install.
do_update now compares the on-disk content hash against the hash the
lockfile recorded at install time; drifted skills are skipped with a
notice and only overwritten with the new --force flag (CLI + /skills
slash path). Bundled skills already had this protection via the
user-modified manifest in hermes update; this brings hub-installed
skills to parity.
Sabotage-verified: disabling the drift check makes the new skip test fail.
Copilot CLI 1.0.79-3 added /worktree new (start a session in a new
worktree). Hermes already has hermes -w launch-time isolation; this adds
the mid-session counterpart: /worktree new [name] creates a tree under
.worktrees/ (remote-tip base, worktree_sync honored), retargets
TERMINAL_CWD + process cwd, and registers the same keep-if-unpushed exit
cleanup. /worktree shows the active tree; /worktree list lists them.
Named trees skip the hermes- prefix so the startup pruner ages them on
the slower named-tree schedule.
CLI parity for the continuity toggle:
- subcommands/cron.py: --continuity on create; --continuity / --no-continuity
tri-state pair on edit (same store_const pattern as --no-agent/--agent)
- cron.py: forwarded to the cronjob tool; created/edited job summaries print
a "Continuity: on" line
- cronjob_tools._format_job: reports continuity as an explicit boolean and
strips the reserved 'self' entry from the reported context_from list
- cron-job.ts: form reader accepts both shapes (raw store record with 'self'
inside context_from, or formatted record with the explicit flag)
- docs: CLI flag examples in the continuity section
E2E (real argparse -> cron_create/cron_edit -> jobs.json in temp HERMES_HOME):
create --continuity stores ['self']; edit --no-continuity clears; edit
--continuity restores; default-off unchanged. 91 cron/tool tests + 16 CLI
cron tests + vitest 10/10 pass.
Per review: expose run-to-run continuity as a boolean `continuity` flag on
cronjob create/update instead of asking users to know the reserved
context_from='self' value. The flag translates to the 'self' entry in
context_from internally (create: appends/omits; update: adds or removes
'self' while preserving other upstream refs). Schema documents the flag and
steers context_from back to job-id chaining only. Docs updated; 7 new tests.
Amp's 'Right on Schedule' (Jul 21 2026) lets scheduled agents wake up with
their saved context and continue where they left off. Hermes cron jobs run
in isolated sessions with per-run amnesia; the existing context_from chain
mechanism only referenced OTHER jobs. This adds the special value 'self'
(and treats a job's own literal id the same way): the job's most recent
output is injected with continuity framing so recurring scouts/monitors
dedupe against what they already reported and continue where they left off.
- cron/scheduler.py: resolve 'self'/own-id in _build_job_prompt with
continuity framing instead of upstream-job framing
- tools/cronjob_tools.py: allow 'self' through create/update validation
(can't be validated against the store — the job doesn't exist yet at
create time); schema description documents the value
- tests: 6 new tests incl. sabotage-verified failures without the fix
- docs: self-context section in cron.md
Perplexity Computer's July update let its agent manage sessions
conversationally from any surface — pin, archive, rename, fork — treating
session organization as operational infrastructure rather than a GUI
nicety. Hermes already has the durable pinned flag in state.db (Desktop
sidebar writes it; auto-archive honors it), but no CLI access existed:
GUI-only management was a single point of failure and blocked scripting
(issue #52955).
- hermes sessions pin <id...> / unpin <id...>: set/clear the durable keep
flag via SessionDB.set_session_pinned (whole compression lineage,
prefix resolution, multi-id, exit 1 on any miss)
- hermes sessions pinned [--json]: list all pinned conversations via the
include_pinned back-fill (old pins can't fall off a paging window);
--json enables backup/restore scripting
- docs: user-guide/sessions.md section
- tests: 6 tests covering prefix resolution, multi-id partial failure,
pinned-only filtering, JSON shape, empty hint
Poke (poke.com) 'encourages users to review recurring automations that
haven't been acted upon'. Hermes' equivalent pain point is a recurring
cron job that fails run after run: each failure delivers the same one-line
error with no signal that the automation itself needs attention.
- cron/jobs.py: persist a failure_streak counter in mark_job_run —
incremented on agent failure, reset on success; delivery failures don't
count. Back-compat: missing field reads as 0.
- cron/scheduler.py: _failure_streak_nudge() appends a review nudge to the
delivered failure summary once a recurring job's streak reaches
cron.failure_nudge_threshold (default 3, 0 disables). One-shots never
nudge.
- hermes_cli/cron.py: 'hermes cron list' shows '(N failures in a row)' on
failing jobs with streak >= 2.
- docs: new 'Repeated-failure review nudge' section in cron.md.
Tests: 17 passed (TestMarkJobRun + TestFailureStreakNudge); E2E verified
with real cron store in temp HERMES_HOME.
Copilot CLI 1.0.78 reworked /rewind to restore only the files the agent
changed, 'skipping any file whose contents no longer match what Copilot
last wrote'. This ports that protection to Hermes checkpoints:
- tools/checkpoint_manager.py: per-project agent-write ledger
(sha256 of every landed write_file/patch), safe_restore_plan()
classifier, and restore(safe=True) that reverts only agent-authored
changes, deletes agent-created files, and preserves user hand-edits.
Empty ledger (pre-existing stores) falls back to the classic full
restore.
- run_agent.py: feed the ledger from _record_file_mutation_result on
every landed mutation (zero new hooks; rides the existing verifier).
- CLI + gateway /rollback: safe mode is the default; --all/--force
restores everything; skipped files are reported with a hint.
- 17 locales: new gateway.rollback.kept_user_edits key.
- Docs: checkpoints-and-rollback.md updated.
- Tests: 7 new cases incl. user-edit preservation, post-agent user
tweaks, agent-created file removal, empty-ledger fallback.
Claude Cowork (Aug 6, 2026) added skill & plugin security scanning:
third-party skills and plugins are automatically checked for malicious
content on upload/edit, returning pass/warn/fail. Hermes already scans
hub-installed skills (tools/skills_guard.py), but `hermes plugins
install` cloned and activated arbitrary Git repos completely unscanned —
and plugins run Python in-process, making them the more dangerous
surface.
- tools/plugin_guard.py: plugin-adapted scanner reusing the skills_guard
pattern engine. Exempts the documented provider-plugin patterns (own
requires_env API-key reads, HTTP calls with keys) on code files while
keeping true threat signals (foreign credential-store access, reverse
shells, destructive/persistence/obfuscation patterns, prompt injection
in docs). Plugin-sized structural limits; VCS/venv dirs excluded.
- hermes_cli/plugins_cmd.py: scan the temp clone before it is moved into
~/.hermes/plugins/. safe=install, caution=confirm (interactive prompt
or --force), dangerous=blocked (--force does NOT override). Re-scan on
`hermes plugins update`; a dangerous updated tree is deactivated until
the user reviews the findings. Dashboard install path returns
structured scan_blocked/scan_findings.
- Config gate: plugins.scan_on_install (default true) in config.yaml.
- Validated against all 60 bundled plugins: 57 safe, 3 caution (real
sudo / curl|sh content in their docs), 0 false-positive blocks.
- 15 new tests incl. E2E through _install_plugin_core with real git
clones.
AGENTS.override.md now takes priority over AGENTS.md in both startup
project-context loading (prompt_builder) and progressive subdirectory
hint discovery (subdirectory_hints). Lets developers keep a personal,
typically-gitignored override next to committed project instructions
without editing the tracked file.
Tracker #79686 P3. Every skill mutation — curator, agent, or user — now
appends one entry to the append-only JSONL ledger at
~/.hermes/skills/.curator_ledger.jsonl, with per-file before/after
manifests whose contents are stored content-addressed (sha256-deduped)
under ~/.hermes/.curator_backups/blobs/.
- tools/skill_ledger.py: append/list/get, blob store, actor derivation
(curator|agent|user), single-entry rollback that takes a pre-rollback
safety entry first and FAILS CLOSED when that capture fails (consistent
with the whole-run tarball rollback hardening from #63366). Path
containment check so a hand-edited ledger can't write outside
HERMES_HOME.
- Hooked all three choke points: skill_manage() dispatch (all actors,
delete intent recorded via absorbed_into/archived evidence),
archive_skill()/restore_skill(), and curator auto-transitions (tagged
actor=curator via a ContextVar override).
- Ledger failures never block the mutation — telemetry, not a gate.
Config gate skills.ledger (default true).
- hermes curator ledger [--skill NAME] [--limit N] and
hermes curator rollback <entry-id> (whole-tree snapshot rollback
unchanged).
- Optional TTL purge of skills/.archive/: curator.archive_ttl_days
(default 0 = never) + explicit hermes curator purge, recorded in the
ledger with before-blobs so purges stay recoverable.
- Docs: curator.md sections on the ledger, single-edit rollback, and
archive TTL purge.
Curator invariants unchanged: only created_by:agent skills auto-transition,
never hard-delete autonomously, pinned exempt; foreground user deletes stay
hard-delete (and are now recoverable via the ledger).
Closes#45778, #50875. Tests adapted from #50261 by @yu-xin-c.
The 'Configure auxiliary models' menu under 'hermes model' now includes a
Delegation entry so the delegate_task subagent model is discoverable and
configurable interactively, instead of requiring hand-edited
delegation.provider / delegation.model keys in config.yaml.
Delegation is not an auxiliary_client task — subagents are full child
agents resolved via tools/delegate_tool.py — so the picker entry writes to
the top-level delegation.* section rather than auxiliary.*. 'auto' (inherit
the parent agent) is persisted as empty strings, never the literal 'auto',
which delegate_tool would try to resolve as a provider name. 'Reset all to
auto' clears only the four delegation routing fields and preserves
non-routing settings like max_concurrent_children.
Rework of the #88049 inline early-return per review:
- resolve_xai_http_credentials gains an opt-in prefer_api_key flag that
checks the explicit XAI_API_KEY first and falls back to OAuth. The key
is read through tools.tool_backend_helpers.resolve_provider_secret
(config -> profile secret scope -> env/.env -> credential pool) so the
preferred path enforces the same scope policy as the existing fallback
branch, including failing closed under a multiplexed gateway turn.
- The preferred path's base URL honors HERMES_XAI_BASE_URL then
XAI_BASE_URL behind hermes_cli.auth._xai_validate_inference_base_url,
mirroring the OAuth branch (a foreign origin can't exfiltrate the key).
- x_search's _resolve_xai_bearer now calls the shared resolver with
prefer_api_key=True instead of re-implementing precedence inline (#88040).
- tools/tts_tool.py _generate_xai_tts converted to the same flag — same
root cause for /v1/tts 403s (#87045, supersedes the inline shape in
#87081 by @enwaiax).
- Regression tests retargeted at the tools.xai_http.get_env_value seam and
the shared resolver; added coverage for the flag's OAuth fallback,
HERMES_XAI_BASE_URL + origin validation, default-order stability, and a
profile-scope-only key on the preferred path.
- Docs: x-search authentication section now states the explicit API key
wins (metered billing implication).
Per review: the protocol belongs only in official Bot Mode interactions,
not every session on a managed install. The prompt builder now injects
the section only when the agent's session row is titled "Bot Chat"
(BOT_CHAT_TITLE, matching the desktop's createCanonicalChat pin and the
`hermes -p <bot> chat -c "Bot Chat"` resume target). Regular sessions
never carry it; the desktop composer middleware owns @mention sends.
Title is read once at first prompt build and the rendered prompt is
cached + DB-restored — cache-safe. E2E against the real AIAgent +
SessionDB: absent in an untitled session, present in Bot Chat,
byte-stable across rebuilds, absent after retitle, absent with the
flag off. Overhead unchanged (~916B, Bot Chat sessions only).
Replaces the plugin-side SOUL.md protocol append: on Bot-Mode-managed
installs (any profile carrying ui_meta['hermes-bots']) the prompt builder
injects the "Messaging other agents" section into every session of every
profile — including headless `hermes -p <bot> chat` sessions a teammate
starts — so bot handoffs work without mutating user-authored SOUL files.
- tools/bot_mode_probe.py: silent-when-unmanaged probe, cached per
(process, home), keyed off the agent's OWN home (not ambient
HERMES_HOME); silent when SOUL.md already carries the legacy section
- agent/system_prompt.py + agent_init.py + config_defaults.py: wired as
agent.bot_mode_protocol (default True), stable tier, byte-stable
across rebuilds (E2E-verified against the real build_system_prompt)
- tui_gateway profiles.list gains bot_mode_protocol capability flag;
the bundled plugin gates ALL SOUL protocol writes on it (backfill,
composeSoul, Edit save) — older gateways keep the SOUL-append path
- overhead: ~916 bytes, only on Bot-Mode installs; zero elsewhere
Supersedes the SOUL backfill half of Hermes-Bot-Mode#99 (credit
@kaduxo — the handle fix, `hermes profile list` correction, and
idempotent-append guards from that PR ship in the bundled plugin).
The runtime-contract repair now also runs during hermes update and once
per session at the first computer_use call (PR #87923); the docs only
mentioned setup and toolset enablement.
The Aug 8 default-on upscaling policy (66ea4e686) chained the Clarity
Upscaler after every sub-2MP generation. Clarity is an SD1.5 creative
tile-diffusion enhancer (creativity 0.35, "masterpiece" prompt prefix) —
it redraws content, which degraded output on 100% of generations for
models like GPT Image 2 and Ideogram whose value is precise text
rendering, CJK, and photorealistic detail.
Policy now: no model upscales by default, on FAL or Krea. The `upscale`
tool param remains as a per-call opt-in (`upscale: true`); explicit
requests still chain Clarity (FAL) / Krea Enhance as before.
- FAL catalog: all 17 default-on entries flipped to upscale=False
- Krea plugin: medium + medium-turbo per-model defaults flipped off
- Tool schema: upscale param described as opt-in with a fidelity warning
- Tests updated: catalog invariant now pins all-off; default-on cases
now assert no upscaler call
- Docs (en + zh) updated to the opt-in policy
Follow-up to #87400: drop the max_iterations and prompt_file knobs from
auxiliary.background_review. The aux model routing (provider/model/
base_url/...) predates #87400 and stays; the enabled switch and the
usage telemetry stay. The fork's iteration budget returns to the
historical hardcoded 16.
Persist fork token usage under session_model_usage task=background_review,
emit a per-fork completion log line, and expose enabled/max_iterations/
prompt_file so operators can see and bound the automatic review cost.
Address review feedback: load auxiliary.background_review once per spawn,
classify completion logs by summarize action prefixes, treat explicit
api_call_count=None as the documented default of 1, and WARNING on the
fail-open enabled-gate path.
Expand user-guide/multi-connection-desktop.md into a complete setup
walkthrough: where to find the pane (settings nav, profile-rail plug,
command palette), the exact add-connection editor fields (Name,
Gateway URL, Authentication: Session token/OAuth, SSH host), Primary /
This device pills, Test semantics, agent roster + profile-rail
switching and per-profile session/cron/messaging scoping, token
storage via Electron safeStorage with the keyring-less Linux plain-
text opt-in, and troubleshooting. All quoted labels match the desktop
i18n strings. Cross-link the rail entry point from desktop.md.
hermes chat -q sets HERMES_INTERACTIVE=1 (for interactive sudo prompts) but
runs one turn with no user waiting to answer approval prompts. Previously a
dangerous command triggered the interactive gate, waited the full 300s
timeout, 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).
Add approvals.single_query_mode (default deny, mirror of cron_mode):
deny — block dangerous commands and execute_code deterministically with
a clear 'no user present' message (no 300s wait)
approve — auto-approve dangerous commands/execute_code in -q mode
cli.py marks the session with HERMES_SINGLE_QUERY_SESSION; the shared gate
(_run_approval_gate, check_all_command_guards, check_execute_code_guard)
treats -q as a deterministic non-interactive context when that marker is set.
execute_code, the -q escape hatch, now honors single_query_mode instead of
auto-approving headlessly. Includes tirith parity in the combined guard and
docs. Fixes#86878.
Adds a `modify` response type to pre_tool_call hooks so a hook can
transform tool arguments before the tool executes, instead of repairing
results afterwards via post_tool_call.
- hermes_cli/plugins.py: _dispatch_pre_tool_call_hooks() fires hooks once
and returns (block_message, modified_args); modify directives
shallow-merge into an accumulated dict built from the original args.
- agent/shell_hooks.py: _parse_response() accepts both the canonical
{"action": "modify", "args": {...}} and Claude Code-compatible
{"decision": "modify", "tool_input": {...}} wire formats.
- model_tools.py, agent/tool_executor.py, agent/agent_runtime_helpers.py:
dispatch sites migrated; modified args applied before execution.
- Docs + 10 new tests (merge semantics, precedence, block interplay).
Salvaged from PR #28953. Best fix for #18988.
#87326 shipped the lean-compaction capability on the compressor; this adds
the config.yaml surface (compression.tail_mode: legacy|lean, default
legacy), DEFAULT_CONFIG entry, and docs on both the dev-guide compression
page and the user-guide configuration page, with zh-Hans parity.
Live-tested against the real cua-driver 0.19.3 binary (Linux x86_64):
- bounded serve flags corrected: the daemon accepts
--session-policy/--approve-session-policy, not the docs'
--capability-manifest names (which it rejects). Verified end-to-end:
a bounded daemon with a real policy file starts and reports running.
- browser-approve verified real but interactive-only (refuses without a
TTY) and its token is a legacy compatibility path disabled by default
on current drivers (per the live browser_prepare schema). Kept as a
passthrough; no longer presented as the primary route.
- NEW primary standard-mode route, verified live: launch the runtime
with cua-driver's trusted-launcher grant. config opt-in
computer_use.grant_existing_profile: true appends
--grant existing-profile to the standard-mode MCP spawn (MCP
initialize verified accepting the flag). Default false = attachment
keeps failing closed. Never applied to bounded/unrestricted daemons.
- Skill, system prompt, tool schema, and docs updated to the verified
ladder: config grant > bounded manifest > YOLO; token = legacy.
Completes the typed cua_browser_* route (PR #74166 lineage) with the
authorization surface that makes existing-profile attachment and
repeatable bounded automation reachable by real users:
- hermes computer-use browser-approve: CLI passthrough that mints
cua-driver's five-minute single-use attachment token for one exact
(pid, window_id). The user, never the model, is the token source.
- approval_token passthrough on cua_browser_prepare (schema + dispatch +
browser_route), forwarded only for existing_profile and only as a
non-empty string.
- computer_use.permission_mode: bounded + capability_manifest config:
private per-session embedded daemon launched with
--capability-manifest/--approve-capability-manifest; missing manifest
fails loudly. 'unrestricted' is deliberately NOT a config value —
it stays bound to the explicit per-session YOLO toggle.
- Skill + system-prompt + docs guidance for the three authorization
rungs and the isolated-profile-first default.
E2E-verified against a temp HERMES_HOME: real config resolution to
bounded, loud failure without a manifest, real argparse path driving a
fake cua-driver binary, standard default preserved.
session=<name> previously set BU_NAME and then skipped backend resolution
entirely — the parameter was documented as cloud-only, so all local/CDP
work funneled through the single default daemon and one IPC socket, and
concurrent sessions (parallel subagents, simultaneous chats) clobbered
each other's browser connection. Reported by @shantanugoel on X.
Now a named session composes with whatever browser source is configured:
- BU_NAME still namespaces the harness daemon (per-name IPC socket, log,
pid — upstream already isolates these), for local Chrome and CDP.
- The /browser connect CDP override is now exported for named sessions
too; previously a named daemon ignored it and fell back to scanning
local Chrome profiles.
- On provider backends (Browserbase, Firecrawl, Nous gateway), the name
keys its own provider browser via the shared _get_session_info cache
(bu-named-<name>), so each name gets its own cloud browser, the same
name reuses one across calls and tasks, and unnamed calls keep the
per-task key.
- Direct-API Browser Use cloud configs keep the native named-daemon path
(provider resolution would double-session and double-bill).
Tool schema/description updated so models reach for session=<name> for
parallel work on any backend, not just cloud.
E2E: two named sessions against a real headless Chrome (real browser-use
CLI, BU_CDP_URL) ran concurrently, set distinct page state, and read it
back intact; sabotage run confirms the new tests fail without the fix.
Phases 3-5 of the multi-connection campaign in one PR (per Teknium), on top
of the registry (#86679) and composite-key backend routing (#86839). Agents
from every registered connection are now usable side by side.
Renderer socket registry (phase 3):
- backendScopeKey moves to apps/shared (@hermes/shared) so main-process pool
keys and renderer socket keys derive from ONE rule; the electron module
keeps a byte-identical twin (tsconfig project boundaries) pinned by a
cross-copy contract test.
- store/gateway secondaries are scope-keyed: entries carry (connectionId,
profile); registry-scoped entries dial through getConnectionFor +
getGatewayWsUrlFor (fresh per-connect OAuth tickets against the right
host); events keep the bare profile plus a connectionId tag; touch/idle
keepalive uses the scope key; pruning keeps entries whose PROFILE has live
work. New ensureGatewayForAgent/openGatewayForAgent fall through to the
profile path for local/null sources — single-source behavior byte-identical.
Union roster + plugin SDK (phases 3+4, the Bot Mode door):
- hermes:agents:roster enumerates every connection's /api/profiles
concurrently (eager REST, lazy sockets; unreachable sources report per-row;
undialed ssh boxes stay connect-on-demand) and flattens through
buildAgentRoster — the @name-device duplicate-handle rule applied once
across all sources, pure + tested.
- SDK: host.connections(), host.agents(), host.warmAgent(),
host.ensureAgent() — feature-detected so plugins degrade cleanly on older
Desktop builds.
Fan-out updates (phase 5):
- hermes:connections:update-all dispatches hermes update to every eligible
source in parallel: local via the app's own applyUpdates pipeline,
remote/ssh via the backend's own POST /api/hermes/update; cloud skipped as
platform-managed (updateEligibility, pure + tested); per-connection result
rows so one dead box can't wedge the batch. Settings → Connections gains
the "Update all instances" button (shown with 2+ connections).
Also: getJsonForBackend/postJsonForBackend helpers with the token/OAuth-cookie
auth split; docs section updated from "staged rollout" to live behavior.
Tests: +4 pure cases (cross-copy contract, roster handles, unreachable
sources, update eligibility); FULL desktop suite 5115 passed; tsc renderer +
electron + shared clean; eslint clean.
The desktop app carried its own hardcoded list of 17 vendor MCP endpoints
(apps/desktop/src/lib/mcp-directory.ts) powering the composer suggestion
pills — a second PR-reviewed vendor list, overlapping and drifting from the
Nous-approved MCP catalog (optional-mcps/).
This makes the catalog the single source of truth:
- manifest schema: optional `suggest:` block (keywords + hosts), parsed,
validated, and normalized in mcp_catalog.py
- 15 new URL-only hosted-remote catalog entries (atlassian, sentry, datadog,
notion, stripe, vercel, supabase, netlify, hugging_face, asana, intercom,
airtable, webflow, paypal, square); figma + linear manifests gain suggest
blocks
- GET /api/mcp/catalog now serves the suggest metadata
- desktop suggestion provider builds its match index from the catalog;
the static directory remains only as a compatibility rung for older
backends without suggest metadata
- setup card source line prefers the catalog entry's transport URL
GitHub stays out of the catalog on purpose: its hosted MCP rejects generic
DCR and the bundled github/* skills (gh CLI) are the stronger integration.
New desktop `github` suggestion provider offers the github-auth skill
instead — gated on a new cached GET /api/git/gh-auth probe so already-
authenticated users never see the pill.
