Have vacuum() return optimize_fts()'s count so the CLI 'sessions optimize'
summary uses the real merged-index count instead of probing the private
_FTS_TABLES / _fts_table_exists() members.
The FTS5 indexes (messages_fts, messages_fts_trigram) grow as a series of
incremental b-tree segments — one per trigger-driven insert batch. SQLite's
automerge caps at ~16 segments, so a long-lived store keeps scanning many
segments per MATCH and never collapses them unless the special 'optimize'
command runs. Nothing in the codebase ever ran it: vacuum() only fired after
a prune that deleted rows, and even then never merged FTS segments.
Changes:
- SessionDB.optimize_fts(): merges each FTS5 index to a single segment,
probing for the (optional/lazy) trigram table first so it is safe to call
unconditionally. Layout-only — search results and snippet() are unchanged.
- vacuum() now calls optimize_fts() before VACUUM so freed index pages are
returned to the OS in the same pass.
- 'hermes sessions optimize' CLI subcommand for on-demand reclamation +
segment compaction (previously there was no way to compact the store
without a prune deleting rows), with before/after size reporting.
Benchmark (8000 msgs, fragmented to 8 segments/index):
- segments 8 -> 1 on both indexes
- porter MATCH 5.5x faster (0.449 -> 0.081 ms/q)
- trigram MATCH 3.0x faster (0.632 -> 0.207 ms/q)
- 8000 matches before == 8000 after, identical row ids (no functional change)
Orthogonal to the structural FTS-size PRs (#20239 external-content,
#27770 optional trigram) — segment merge helps regardless of those.
Tests: TestOptimizeFts covers index count, search+snippet preservation,
missing-trigram path, and idempotency. Full test_hermes_state.py green (227).
The rotation flowchart only described the generic 'retry once, rotate on
second 429' path. ChatGPT/Codex plan-limit 429s carry a usage_limit_reached
reason and rotate to the next pool key immediately (no retry, since the cap
won't clear on retry). Document that case so the docs match the code.
Adds a `grok` skill under `skills/autonomous-ai-agents/`, a third coding-agent orchestration guide alongside `codex` and `claude-code`. It teaches Hermes to delegate coding tasks to Grok Build (xAI's `grok` CLI).

Two CI flakes surfaced on PR #34572 (both in files this PR doesn't touch;
pre-existing host-dependent flakes):
1. test_process_registry::TestPopenLeakOnSetupFailure — the failure-cleanup
tests use a fake proc.pid (8888/9999) and assert proc.kill() runs. But
spawn_local's primary cleanup is os.killpg(os.getpgid(pid), SIGKILL),
falling back to proc.kill() only on ProcessLookupError/PermissionError/
OSError. When the fake PID happens to exist on a busy host, os.getpgid
succeeds, os.killpg fires against an UNRELATED real process group, and
proc.kill() is never reached -> flaky AssertionError (and a real risk of
SIGKILLing an innocent process group from a unit test). Patch os.getpgid
to raise ProcessLookupError so the fallback path runs deterministically
and no real killpg is ever issued.
2. test_web_server::test_resize_escape_is_forwarded — the receive loop calls
the blocking conn.receive_bytes() with no exception guard. Once the child
prints its winsize and exits, the PTY closes; on a missed-marker run the
next recv blocks until the 30s pytest-timeout instead of failing fast.
Add a try/except break (matching the working sibling tests) and bump the
child's pre-read sleep 0.15s -> 0.5s so the resize reliably lands first.
Verified: 4/4 pass across 3 consecutive runs; root cause for #1 reproduced
(os.getpgid(1) succeeds -> old code skips proc.kill).
_adapter_enforces_own_access_policy accessed self.adapters directly, but
several auth tests build a bare GatewayRunner via object.__new__ without
setting .adapters (pitfalls.md #17). Read it defensively with getattr so a
missing/empty adapter map means "no adapter owns the policy" instead of
raising AttributeError.
Fixes 4 tests: test_feishu_bot_auth_bypass, test_discord_bot_auth_bypass (x2),
test_signal::test_signal_in_allowlist_maps.
Config-driven platform policies (dm_policy / group_policy / allow_from /
group_allow_from) for WeCom, Weixin, Yuanbao, and QQBot now work without
also setting a PLATFORM_ALLOWED_USERS env var.
These adapters enforce their access policy at intake — a message is dropped
inside the adapter and never dispatched unless it already passed the policy.
The gateway's env-based check (_is_user_authorized) ran afterward and, with
no env allowlist set, fell through to an env-only default-deny — silently
rejecting `dm_policy: open` and config-only allowlists the adapter had
already authorized.
Rather than re-implement each adapter's policy a second time in run.py
(which would drift), adapters that own their gate now declare it via a new
BasePlatformAdapter.enforces_own_access_policy property (default False). The
gateway trusts that flag and skips the env-only default-deny for those
platforms. Env allowlists still take precedence when set.
Also resolves unauthorized DM behavior from config dm_policy so allowlist /
disabled policies drop unauthorized DMs silently instead of leaking pairing
codes, while an explicit pairing policy opts back in.

Follow-up for #30240 — the new page was not referenced in sidebars.ts,
leaving it orphaned (unreachable via nav and flagged as a broken relative
link to ./profiles.md). Added under Using Hermes after profile-distributions.
Covers running multiple Hermes profiles as managed services on one host:
- A shell-loop wrapper pattern for start/stop/restart/status across every
profile (the per-profile CLI commands stay unchanged).
- Per-platform service file locations (LaunchAgent on macOS, systemd user
unit on Linux), plus the rules around clashes.
- Log paths per profile and how to tail every gateway at once.
- Config file layout per profile and the restart-after-edit workflow.
- Keeping the host awake: caffeinate flags on macOS,
systemd-inhibit + loginctl enable-linger on Linux.
- Token-conflict auditing across .env files.
- Troubleshooting for the common "Could not find service in domain for
user gui: 501" message and stale PIDs after a crash.
Tested locally with five profiles on macOS launchd.

* fix(security): block AWS SDK creds from subprocess env
* fix(security): narrow Bedrock subprocess strip to inference bearer token only
Scopes the AWS_SDK subprocess strip down from the full AWS credential chain
to just AWS_BEARER_TOKEN_BEDROCK — the only Hermes-managed *inference* secret
(analogous to OPENAI_API_KEY). The general AWS credential chain
(AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY / AWS_SESSION_TOKEN / AWS_PROFILE
/ config + role pointers) is intentionally left inheritable.
Why: per SECURITY.md §3.2 the local terminal is the user's trusted operator
shell. Hard-blocklisting the general chain would (a) regress *every* user who
runs aws/terraform/cdk/boto3 in the agent terminal — not just Bedrock users,
since PROVIDER_REGISTRY is iterated unconditionally at import — and (b) be
unrecoverable, because env_passthrough.py refuses to re-allow anything in
_HERMES_PROVIDER_ENV_BLOCKLIST (GHSA-rhgp-j443-p4rf). The narrow strip closes
the reported leak (opencode enumerating the Bedrock catalog off the leaked
bearer token) with no capability loss.
Keeps zapabob's self-healing auth_type=="aws_sdk" mechanism so any future
SDK-cred provider is covered automatically.
Tests: bearer token stripped + general chain preserved (no-regression guard),
on both the runtime strip path and the blocklist-membership path.

* feat: embedder environment-hint hook for the system prompt
Adds HERMES_ENVIRONMENT_HINT env var (and config.yaml agent.environment_hint)
so a host wrapping Hermes (sandbox runner, managed platform) can describe the
runtime environment — proxy, credential handling, mount layout — in the system
prompt's environment-hints block, without editing the identity slot (SOUL.md).
Read once at prompt-build time, so it lands in the stable, cache-safe portion
of the system prompt. Env var overrides the config key (build-time/container
mechanism). Empty by default — no behavior change for existing installs.

The setup guide was missing the specific Feishu permission scopes to
configure and the event subscription (im.message.receive_v1) needed
for the bot to receive messages. Users had to reference external
OpenClaw documentation to complete the setup.
Adds:
- Required permissions table (im:message, im:message:send_as_bot,
im:resource, im:chat, im:chat:readonly)
- Recommended permissions (reactions, app info, contact)
- Event subscription step (im.message.receive_v1)
- App version publish reminder (permissions require published version)
Web search/extract dispatch read agent.web_search_registry before plugin
discovery had run, so in any process that hadn't imported model_tools.py
(subprocess agent runs, delegate children, standalone scripts) the registry
was empty: get_provider('firecrawl') returned None and the dispatcher emitted
the misleading 'No web extract provider configured' error even with
web.extract_backend set and FIRECRAWL_API_KEY exported.
Adds an idempotent _ensure_web_plugins_loaded() helper (mirrors
tools.browser_tool._ensure_browser_plugins_loaded) and calls it at the top of
both the web_search_tool and web_extract_tool dispatch sites before the
registry lookup.
Fixes#27580.

The fast-path decision (native routing + provider allowlist OR
supports_vision override) lived inline in vision_analyze and was copied
into browser_vision. Extract it to _should_use_native_vision_fast_path()
so both tools share one source of truth.
- vision_tools: gate logic now one helper; vision_analyze calls it in 3 lines
- browser_tool: thin envelope decoration over the shared helper, not a copy
- browser_vision typed Union[str, Dict] to match its real return shape
- tests slimmed to target the override path + text-mode-wins invariant
The _on_reaction approval handler used:
if self._allowed_user_ids and sender not in self._allowed_user_ids:
When MATRIX_ALLOWED_USERS is not configured, _allowed_user_ids is an
empty set. The short-circuit on the empty set caused the deny block to
never execute, allowing any Matrix room member to approve or deny tool
calls via ✅/❎ reactions — even users that run.py's _is_user_authorized
would reject for regular messages.
Fix mirrors the Telegram _is_callback_user_authorized fix (commit
89d32052e, PR #28494): deny by default when no allowlist is configured,
unless GATEWAY_ALLOW_ALL_USERS=true is explicitly set.
Follow-up mitigation for the #27303 env-scrub tightening. Dropping the
broad HERMES_ prefix in favor of a 4-var operational allowlist is correct
hardening, but a sandbox script that imports a repo module reading a
non-allowlisted HERMES_* var at import time would otherwise see it
silently unset. _scrub_child_env now emits a one-shot debug log naming the
dropped non-secret HERMES_* vars and pointing at the env_passthrough
opt-in escape hatch. Secret-shaped vars are never named in the log.
Tests: dropped vars are logged + env_passthrough named; no log when
nothing is dropped; secret vars excluded from the diagnostic.
Cover context+callback propagation and teardown-clears, a source guard that both RPC threads stay wrapped, the check_execute_code_guard decision matrix (isolated backend, headless-local, cron-deny, gateway approve/deny/timeout/missing-notify, smart mode, session-yolo), the env-scrub allowlist/secret rules, and a behavioral test that execute_code() blocks before spawning on denial.
Refs #4146, #27303, #30882, #33057
When approvals.mode=manual with security.tirith_enabled off and no auxiliary.approval model, dangerous commands and execute_code scripts can only be gated by live in-chat approval; with routing fixed they now fail closed (block) rather than silently auto-run. Surface that at startup so operators knowingly enable tirith or auxiliary.approval for unattended gateways.
Refs #30882
Wrap both execute_code RPC threads (local UDS + remote file-RPC) with propagate_context_to_thread so gateway sessions no longer fall into check_dangerous_command's non-interactive auto-approve branch and the CLI approval prompt stays reachable. Add check_execute_code_guard: one-shot fail-closed approval of the whole script in gateway/ask/cron-deny before the child spawns (skips isolated backends; command-string built only past the early returns). Drop the broad HERMES_ env passthrough for an explicit operational allowlist plus DSN/WEBHOOK secret substrings, and update the POSIX-equivalence oracle.
Refs #4146, #27303, #30882, #33057
Worker threads that dispatch Hermes tools started with an empty contextvars.Context and no thread-local approval/sudo callbacks. Add tools/thread_context.propagate_context_to_thread factoring that capture/install/clear lifecycle (mirrors the GHSA-qg5c-hvr5-hjgr pattern), and refactor agent/tool_executor onto it so the security-critical logic lives in one audited place. Update the contextvar-propagation source guard for the new call shape.
Refs #33057
After the legacy session-key path was removed, two parameters became dead
surface on the Nous runtime-resolution chain:
- min_key_ttl_seconds: del'd inside refresh_nous_oauth_pure and pass-through /
telemetry-only in refresh_nous_oauth_from_state, _try_import_shared_nous_state,
_nous_device_code_login, and resolve_nous_runtime_credentials. It controlled the
now-deleted agent-key mint TTL and drives no behavior.
- inference_auth_mode: with the legacy mode gone, AUTO and FRESH are behaviorally
identical; the value only fed _normalize_nous_inference_auth_mode validation and
oauth trace output, never a branch.
Removing inference_auth_mode orphaned its whole supporting cluster
(NOUS_INFERENCE_AUTH_MODE_AUTO/FRESH, NOUS_INFERENCE_AUTH_MODES,
_normalize_nous_inference_auth_mode), and dropping min_key_ttl_seconds orphaned
DEFAULT_AGENT_KEY_MIN_TTL_SECONDS — all deleted here.
Updated every caller (run_agent, auxiliary_client, credential_pool, proxy adapter,
runtime_provider, web_server, main, auth_commands, setup) and pruned the matching
test kwargs. Deleted two tests that exercised the removed surface
(test_legacy_auth_mode_is_rejected, test_try_refresh_..._accepts_explicit_auth_mode).
No behavior change: net -134 LOC of dead code.
The import-failure fallback returned any 3-segment token without scope/
expiry validation, a divergent reimplementation of the canonical
_nous_invoke_jwt_is_usable check. The import is from the same module that
provides resolve_nous_runtime_credentials, so a failure means the whole
auxiliary Nous path is unavailable anyway; return "" instead so the caller
falls through to the clear 'run: hermes auth add nous' guidance rather than
handing back an unvalidated token.
The live harness runs against a real OpenRouter key; record['error'] is a
full traceback that, on an auth failure, could echo a request header or URL
containing the key. _redact_secrets() now masks the live OPENROUTER_API_KEY,
any sk-/sk-or- bearer token, and Authorization/Bearer headers before
final_response and error enter the transcript or the console print. Addresses
the CodeQL clear-text-storage/logging findings at the source.
The scoping fix added enabled_toolsets/disabled_toolsets to the
agent_runtime_helpers sequential dispatch into handle_function_call, so
test_invoke_tool_dispatches_to_handle_function_call's assert_called_once_with
(exact match) needs the two new kwargs. Both are None for the default agent
fixture.
Brings in the tool_search live-test harness from the original PR but leaves
out the 11 checked-in scripts/out/*.json transcript files — those are
non-deterministic model output that goes stale the moment the model changes
and were the bulk of the diff. scripts/out/ is now gitignored so a harness
run never re-commits them.
Fixes on top:
- API-key loading goes through hermes_cli.env_loader.load_hermes_dotenv
instead of hand-parsing ~/.hermes/.env and assigning the value to a local.
The canonical loader never materializes the secret in a local variable in
this module, which clears the four CodeQL high alerts
(py/clear-text-storage / py/clear-text-logging-sensitive-data at the
transcript write/print sites — they were tracing the key from the
hand-rolled parser into the records) and removes a hand-rolled parser.
- encoding='utf-8' on every write_text/read_text in both harness scripts
(Windows-footgun hygiene).

Tool Search read its catalog from the global registry (get_tool_definitions
with no toolset scope = 'start with everything'), so a restricted-toolset
session — subagent, kanban worker, curated gateway session — could:
1. tool_search the entire process registry, not just its granted tools, and
2. tool_call any registered plugin/MCP tool it was never given, because
registry.dispatch() has no enabled_tools gate for non-execute_code tools.
A scoped session (enabled_toolsets=['mcp-github']) reported total_available=26
and successfully invoked an out-of-scope plugin tool via tool_call.
Fix:
- handle_function_call gains enabled_toolsets/disabled_toolsets; the bridge
dispatch scopes get_tool_definitions to them (also stops polluting the
process-global _last_resolved_tool_names with out-of-scope tools, which
leaked into execute_code's sandbox-tool fallback).
- A defense-in-depth gate rejects any tool_call'd name not in the scoped
deferrable catalog.
- tool_executor's unwrap (both concurrent + sequential paths) enforces the
same scope before dispatch, since it unwraps tool_call -> underlying name
and bypasses the bridge branch. New _tool_search_scoped_names() helper,
cached per-agent on registry generation + toolset scope.
- New scoped_deferrable_names() helper in tool_search.py shared by both sites.
Tests: 4 new regression tests in TestRegression_ToolsetScoping (scoped
catalog, out-of-scope tool_call rejection, no global pollution, helper).
Adds Tool Search, a structured-tools progressive-disclosure layer that
replaces MCP and non-core plugin tools in the model-visible tools array
with three bridge tools (tool_search / tool_describe / tool_call) when
the deferrable surface would consume more than a configurable percentage
of the active model's context window. Core Hermes tools are never deferred.
Default mode is 'auto' with a 10% context threshold, so small toolsets
pay no overhead. Set tools.tool_search.enabled to 'on' to force or 'off'
to disable.
Design carefully reflects the OpenClaw production failure modes
documented in the openclaw-tool-search-report:
- Core tools never defer (toolsets._HERMES_CORE_TOOLS). Addresses the
'tools silently missing from isolated cron turns' regression class
(openclaw#84141) by construction: there is no code path that can
drop a core tool.
- Catalog is stateless across turns — rebuilt from the live tool-defs
list on every assembly. No session-keyed Map that can drift out of
sync with the registry.
- tool_call unwraps the bridge call before any hook fires, so plugin
pre/post hooks, guardrails, approval flows, and the activity feed
all see the underlying tool name, not the bridge (addresses
openclaw#85588 and the verbose-mode complaint on openclaw#79823).
- The unwrap happens in both the parallel and sequential paths of
agent/tool_executor.py and also in handle_function_call, so direct
callers (sandboxed code, eval harnesses) are covered too.
- Bridge tools cannot invoke each other (recursion guard) and cannot
invoke core tools (those must be called directly).
- Tools mode only — no JS-sandbox code-mode. Keeps the surface small.
- Token estimation via cheap char/4 heuristic; precision isn't needed
for the threshold decision.
Files:
- tools/tool_search.py — new module (BM25 retrieval, classification,
threshold gate, bridge dispatch, unwrap helper).
- tests/tools/test_tool_search.py — 35 tests including the OpenClaw
#84141 regression guard.
- model_tools.py — wires assembly into _compute_tool_definitions as the
final step, adds skip_tool_search_assembly kwarg so the bridge can
see the real catalog, dispatches the three bridge tools.
- agent/tool_executor.py — unwraps tool_call in both parallel and
sequential parsing loops so checkpointing, guardrails, plugin hooks,
and tool-progress callbacks all observe the underlying tool name.
- hermes_cli/config.py — DEFAULT_CONFIG['tools']['tool_search'] block.
- website/docs/user-guide/features/tool-search.md — user docs.
Validation:
- 35/35 new tests pass.
- Existing tool/registry/model_tools/config/coercion/executor tests
(82 + 74 + small adjacents) green.
- Live E2E: 20 fake MCP tools registered, get_tool_definitions returns
3 bridges, tool_search returns top 3 hits, tool_describe returns
full schema, tool_call dispatches to the real underlying handler
and the underlying result is what the model sees.
- Reserved-name recursion guard verified live.
- Core-tool refusal via tool_call verified live.
The chatgpt.com/backend-api/codex endpoint can spend tens of seconds in
backend admission / prompt prefill before emitting its first SSE event. The
12s no-byte TTFB cutoff aborted those still-valid streams, surfacing as
'Codex stream produced no bytes within 12s' through all retries (Discord
reports). The OpenAI SDK's own streaming read timeout is 600s, so 12s was
~50x more aggressive than the transport layer would have tolerated.
Default the no-byte cutoff to 120s and raise the openai-codex MAX cap default
to 120s so it no longer clamps the new default back to 20s. Disabling stays
available via HERMES_CODEX_TTFB_TIMEOUT_SECONDS=0; the 25k-token auto-disable,
_STRICT override, and post-first-event idle watchdog are unchanged.

A process running mismatched module versions — conversation_compression.py
re-imported with the post-#34351 lock code while a long-lived
hermes_state.SessionDB stays bound to the pre-#34351 class in memory — has
the try_acquire_compression_lock call site but not the method. The
AttributeError it raises is NOT a sqlite3.Error, so the method's own
fail-open guard never runs; the exception escapes to the outer agent loop,
which prints the error and retries. Compression never succeeds, the token
count never drops, and the loop re-triggers compaction forever (the
'API call #47/#48/#49 ... has no attribute try_acquire_compression_lock'
spin a user hit after an update).
Wrap the lock acquire so any unexpected exception fails OPEN: skip locking
and proceed with compression. Skipping the lock risks a rare
concurrent-compression session fork; an infinite no-progress loop that never
compresses at all is strictly worse. The remediation hint in the log points
at the real fix (restart / hermes update to resync the stale module).
Also guards get_compression_lock_holder against the same skew.
Adds a regression test simulating the version skew (real SessionDB wrapped
so only the lock methods raise AttributeError) — asserts _compress_context
proceeds and rotates instead of raising.
