The Windows branch of `_terminate_host_pid` early-returned after
`os.kill(pid, SIGTERM)` (which Python maps to `TerminateProcess` for
the target handle only), leaving descendant processes — e.g. Chromium
renderer/GPU/network helpers spawned by an `agent-browser` daemon —
running on Windows even after the preceding commit fixed POSIX.
The right Windows primitive is `taskkill /PID <pid> /T /F`:
`/T` walks the tree, `/F` force-terminates. Same approach
`gateway.status.terminate_pid(force=True)` already uses for the
gateway's own shutdown path; reuse the same shape here.
Why NOT extend the POSIX psutil tree-walk to Windows:
1. Windows doesn't maintain a Unix-style process tree. `psutil.
Process.children(recursive=True)` walks PPID links that go stale
when intermediate processes exit, so enumeration is best-effort
and silently misses orphaned descendants. The whole bug we're
fixing is orphaned descendants.
2. `psutil.Process.terminate()` on Windows is `TerminateProcess()`
for one handle — same single-PID scope as the existing
`os.kill`. The existing comment in `gateway/status.py::
terminate_pid` warns this explicitly: 'os.kill SIGTERM is not
equivalent to a tree-killing hard stop' on Windows.
3. Headless Chromium has no GUI window, so the softer
`taskkill /T` without `/F` (which sends WM_CLOSE) won't reach
it either. `/F` is required.
POSIX path is unchanged. The taskkill subprocess uses the same
`creationflags=windows_hide_flags()` pattern other Windows shellouts
in this codebase use. `FileNotFoundError` / `TimeoutExpired` /
`OSError` fall back to bare `os.kill(SIGTERM)` as cheap insurance.
Tests cover the Windows branch via the codebase's standard
`monkeypatch _IS_WINDOWS` pattern (`references/windows-native-
support.md`), plus POSIX tree-walk order, NoSuchProcess swallow,
and the OSError fallback path. 7 new tests, all green on Linux CI.
os.kill(pid, SIGTERM) only signals the parent, leaving Chromium child
processes (renderer, GPU, etc.) orphaned. Reuse the existing
ProcessRegistry._terminate_host_pid() helper which walks the process
tree leaf-up via psutil, terminating children before the parent.
Trim ~600 LOC off the original contribution while keeping the same
operator-facing surface and detection coverage.
- Collapse three entry points (file / dir / bundle) into one
ast_scan_path(path) that handles both files and directories.
- Drop AstFinding dataclass + severity field — replaced with plain
(file, line, pattern_id, description) tuples. Severity ordering was
display-only for a diagnostic that explicitly disclaims security
verdicts, so the field added bookkeeping without earning its place.
- Replace Rich-markup formatter with plain text grouped by file.
- Drop the 'inspect --ast-deep' surface — same scanner, same output as
'audit --deep', single CLI entry is enough. Operators audit after
install; pre-install inspection signal isn't worth the second surface.
- Trim test file to the cases that earn their place: bypass payload,
syntax error survival, RecursionError survival, false-positive guard
(importer lookalike), literal-arg false-positive guard, non-.py
ignored, directory recursion + cache-dir skipping, missing-path,
getattr/__dict__ detection, formatter empty + populated.
Net: tools/skills_ast_audit.py 353 -> 133 LOC,
tests/tools/test_skills_ast_audit.py 299 -> 103 LOC, full diff
+704/-12 -> +264/-6. No change to tools/skills_guard.py — Skills Guard
verdicts remain untouched per SECURITY.md §2.4.
Add opt-in AST diagnostics for skill review without making Skills Guard stricter by default.
- Add hermes skills inspect --ast-deep to scan fetched skill bundles before installation
- Add hermes skills audit --deep to scan already-installed hub skills
- Keep AST analysis in tools/skills_ast_audit.py, separate from tools/skills_guard.py
- Label output as diagnostic hints, not security verdicts
- Cover dynamic import/access patterns: importlib, __import__(computed), getattr(computed), and __dict__[computed]
This follows the maintainer guidance from closed PR #7436: useful AST-level analysis belongs in an opt-in diagnostic path, not in Skills Guard's default heuristic scan.
ntfy now ships as a self-contained plugin under plugins/platforms/ntfy/
instead of editing 8 core files (gateway/config.py Platform enum,
gateway/run.py factory + auth maps, cron/scheduler.py, toolsets.py,
hermes_cli/status.py, agent/prompt_builder.py, gateway/channel_directory.py,
tools/send_message_tool.py).
All routing goes through gateway/platform_registry via register_platform():
- adapter_factory, check_fn, validate_config, is_connected
- env_enablement_fn seeds PlatformConfig.extra from NTFY_* env vars so
gateway status reflects env-only setups without instantiating httpx
- standalone_sender_fn handles deliver=ntfy cron jobs when cron runs
out-of-process from the gateway
- allowed_users_env / allow_all_env hook into _is_user_authorized
- cron_deliver_env_var=NTFY_HOME_CHANNEL for cron home routing
- platform_hint surfaces in the system prompt
- pii_safe=True (topic names are the only identifier; no PII to redact)
Tests moved to tests/gateway/test_ntfy_plugin.py using _plugin_adapter_loader
so the module lives under plugin_adapter_ntfy in sys.modules and cannot
collide with sibling plugin-adapter tests on the same xdist worker. The
core-file grep tests (Platform.NTFY in source, hermes-ntfy in toolsets,
etc.) are replaced with plugin-shape tests covering register() metadata,
env_enablement_fn output, and standalone_sender_fn behavior.
68 tests pass under scripts/run_tests.sh.
User incident (Slack, 2026-05-13): user walked away mid-conversation,
agent requested approval to run `rm -rf .git`, the prompt timed out
after the gateway_timeout (default 300s), and the agent removed the
.git folder on its own. Corroborated by an independent report from a
Telegram user.
The underlying code path was correct — `check_all_command_guards`
returns `approved=False` with a BLOCKED message on both timeout and
explicit deny, and `terminal_tool` surfaces that as `status=blocked`
to the agent. The bug is at the model-interface layer: the message
"BLOCKED: Command timed out. Do NOT retry this command." reads to
some models as "try a different command achieving the same outcome."
This commit changes only the model-facing message + the structured
return shape:
- Timeout message now explicitly names the three evasion paths the
agent must avoid: retry, rephrase, AND achieve the same outcome
via a different command. Ends with "Silence is not consent."
- Explicit deny gets the same shape minus the silence-is-not-consent
line (it WAS an explicit deny, not silence).
- New structured fields on the return dict: `outcome` ("timeout"
or "denied") and `user_consent` (always False on this branch)
so plugins, hooks, and audit pipelines don't have to string-parse
the message to distinguish the two cases.
The mechanism that should already have prevented the original incident
— timeout treated as deny, BLOCKED result, post hook fires with
`choice="timeout"` — is unchanged. This commit hardens only the
agent's reading of the result.
Tests:
- test_timeout_returns_approved_false_with_no_consent — pins the
return shape on the Slack-shaped notify_cb-registered path
- test_timeout_message_is_emphatic_against_retry_and_rephrase —
pins the exact phrases the message must contain
- test_explicit_deny_carries_same_no_consent_shape — same contract
on explicit /deny
- test_timeout_emits_post_hook_with_timeout_outcome — pins the
post_approval_response hook payload so audit plugins can act
329 approval tests passing (4 new + 325 existing).
Fixes#24912
Reproduction (production, 2026-05-14): two concurrent sessions on the
same agent. Session A patches MEMORY.md directly via the patch tool,
appending ~8KB of structured content (Vendor Master, Standing Orders,
Pin Board) — none of it through the memory tool, so no § delimiters.
Session B starts later with stale in-memory state (1 entry, ~331
chars). Session B calls memory(action=replace) on its one known
entry. The tool's _read_file parses A's content as a single 8KB
'entry' (no § splits), then replace truncates that entry to B's new
333-byte content. ~8KB of structured content silently destroyed.
The atomic-rename write path is fine in isolation. The bug is the
implicit contract: the tool assumes MEMORY.md is exclusively a
§-delimited list of small entries it wrote, but the v0.13 install
runbook itself uses 'cat >> MEMORY.md' for onboarding, the patch tool
edits the file directly, and operators do too.
Fix: a drift guard in MemoryStore._detect_external_drift that fires
on either signal:
1. Re-parse + re-serialize doesn't produce identical bytes
(catches oddly-encoded delimiters / partial writes).
2. Any single parsed entry exceeds the store's whole-file char
limit. The tool budgets the ENTIRE store against that limit
(2200 chars for memory, 1375 for user), so no tool-written
entry can legitimately be larger. An entry bigger than the
store limit means an external writer dropped free-form content
into what the tool will treat as one entry.
When drift fires, _reload_target writes a .bak.<ts> snapshot of the
on-disk file, then add/replace/remove refuse to flush. The original
file stays untouched. The error dict surfaces the .bak path AND a
remediation string ('integrate missing entries via memory(add=...)
one at a time, then rewrite the file clean') so the model can act on
it without escalating to the operator.
Tests:
- test_replace_refuses_on_drift, test_add_refuses_on_drift,
test_remove_refuses_on_drift — all three mutators refuse
- test_clean_file_does_not_trigger_drift — false-positive check
- test_error_message_points_at_remediation — error string shape
- test_drift_guard_also_protects_user_target — USER.md too
- test_drift_backup_filename_is_unique_per_invocation — bak.<ts>

144 memory tests passing (was 137; +7).
Fixes#26045
Follow-up to @sprmn24's verdict-logic fix. The previous block-message
ended in 'Use --force to override' regardless of verdict — but as of
the --force fix above, dangerous community/trusted skills can't be
overridden by --force at all. The misleading hint sends users in a
loop. Replace it with a specific message that tells them what the
documented behavior actually is.
Adds two regression tests covering the dangerous-verdict message
shape and one that pins the existing --force hint for non-dangerous
blocks.
- _determine_verdict() returned 'caution' for medium/low-only findings,
causing community skills with harmless patterns (e.g. path traversal
notation, unpinned pip install) to be incorrectly blocked. Now returns
'safe' when only medium/low severity findings are present.
- should_allow_install() allowed --force to override 'dangerous' verdict,
contradicting documented behavior that --force does NOT override dangerous
scan results. Added explicit check to prevent force-installing skills
with dangerous verdict.
read_file_tool resolves relative paths against TERMINAL_CWD (or the
task's live terminal cwd), but the prior call passed the original
unresolved string to get_read_block_error. That function's own
resolve() is anchored at the Python process cwd, so when a task's
TERMINAL_CWD pointed at HERMES_HOME and the agent issued read_file
on the relative path "auth.json", the credential-store denylist was
never reached and the file was read normally.
Pass the already-resolved absolute path string at the file_tools call
site, document the contract on get_read_block_error, and add a
read_file_tool-level regression test that pins the relative-path
case under TERMINAL_CWD == HERMES_HOME.

PR #6656 added rel_path + \x00 prefixing to ``bundle_content_hash`` so a
filename swap between two files in a bundle changes the digest. But it
only patched the in-memory side — ``content_hash`` in ``tools/skills_guard.py``
(the on-disk equivalent) still hashed file contents only.
These two functions need to stay symmetric: ``check_for_skill_updates``
compares the disk hash of an installed skill against the bundle hash
of the upstream copy. With the asymmetric fix, every clean install
showed as drifted because the digests no longer matched
(2 existing tests in ``test_skills_hub.py`` started failing as soon as
the contributor's change landed).
Apply the same ``rel_path + \x00 + content`` shape to the disk-side
function. Both functions now produce the same digest for the same skill
content laid out two ways. Documented the symmetry invariant in the
docstring so a future change to either function knows to touch both.
Also adds tests/tools/test_pr_6656_regressions.py with 10 regression
tests covering all three fixes salvaged in PR #6656:
- uninstall_skill path traversal (4 cases: parent segments, absolute
paths, symlink escape, legitimate skill)
- bundle_content_hash filename swap detection (4 cases: in-memory
swap, identity, disk-side swap, bundle↔disk symmetry)
- list_pending lock contract (2 cases: source-grep contract, smoke)
Also fixes AUTHOR_MAP entry for @aaronlab — their commit email
(1115117931@qq.com) maps to "aaronagent" which isn't a real GitHub
login, so changelog @mentions would 404.
- skills_hub: validate that uninstall_skill's install_path resolves
inside SKILLS_DIR before calling shutil.rmtree, preventing recursive
deletion of arbitrary directories via poisoned lock.json entries
- skills_hub: include file paths (not just contents) in
bundle_content_hash so swapping filenames between files changes the
hash, strengthening update-detection integrity
- pairing: wrap list_pending() in self._lock so _cleanup_expired() file
writes don't race with concurrent generate_code()/approve_code() calls

First migration of an existing built-in platform adapter to the plugin
system established by IRC / Teams / LINE / Google Chat. Closes#24325;
advances the umbrella refactor in #3823.
Matches Teams' shape exactly — adapter under ``plugins/platforms/discord/``
with the standard ``__init__.py`` / ``adapter.py`` / ``plugin.yaml``
shell, ``register(ctx)`` entry point, **no back-compat shim** at the old
import path, and full parity for the four hooks Teams uses plus the
``apply_yaml_config_fn`` hook that landed in #25443 (the Discord plugin
is the first consumer of that hook):
* ``standalone_sender_fn`` — out-of-process cron delivery via REST API
* ``setup_fn`` — interactive ``hermes setup gateway`` wizard
* ``apply_yaml_config_fn`` — translate ``config.yaml`` ``discord:`` keys
into ``DISCORD_*`` env vars (replaces the hardcoded block in
``gateway/config.py``)
* ``is_connected`` — declares connection state from ``DISCORD_BOT_TOKEN``
* ``check_fn`` — lazy-installs ``discord.py`` on demand
* plus ``allowed_users_env``, ``allow_all_env``, ``cron_deliver_env_var``,
``max_message_length``, ``emoji``, ``required_env``, ``install_hint``
* ``gateway/platforms/discord.py`` (5,101 LOC) →
``plugins/platforms/discord/adapter.py`` (git rename, R090).
* New ``plugins/platforms/discord/{__init__.py, plugin.yaml}`` with
``requires_env`` / ``optional_env`` declarations.
* Append ``register(ctx)`` block + new hook implementations
(``_standalone_send``, ``interactive_setup``, ``_apply_yaml_config``,
``_clean_discord_user_ids``, ``_is_connected``, ``_build_adapter``,
plus helpers ``_DISCORD_CHANNEL_TYPE_PROBE_CACHE`` etc.) to the
adapter.
* Replace the ``Platform.DISCORD elif`` branch in
``GatewayRunner._create_adapter()`` (−9 LOC) with a generic post-creation
hook (+6 LOC) in the registry path: any plugin adapter that declares a
``gateway_runner`` attribute now gets it auto-injected. Webhook's
built-in branch is unchanged (it doesn't go through the registry path).
* Move ``_send_discord`` (190 LOC) and helpers
(``_DISCORD_CHANNEL_TYPE_PROBE_CACHE``, ``_remember_channel_is_forum``,
``_probe_is_forum_cached``, ``_derive_forum_thread_name``) from
``tools/send_message_tool.py`` into the plugin as ``_standalone_send``.
* Wire via ``standalone_sender_fn=_standalone_send`` (Teams pattern; same
gap fixed in #21804 for other plugin platforms).
* Replace the Discord ``elif`` in ``tools/send_message_tool.py``
``_send_to_platform`` with a 10-line registry-hook dispatch.
* Drop the ``DiscordAdapter`` import and the
``Platform.DISCORD: DiscordAdapter.MAX_MESSAGE_LENGTH`` ``_MAX_LENGTHS``
entry — the registry's ``max_message_length=2000`` covers it.
* Move ``_setup_discord`` and ``_clean_discord_user_ids`` (68 LOC) from
``hermes_cli/setup.py`` into the plugin as ``interactive_setup``.
* Wire via ``setup_fn=interactive_setup``. CLI helpers (``prompt``,
``print_info``, etc.) are lazy-imported so the plugin's module-load
surface stays minimal.
* Remove ``"discord": _s._setup_discord`` from
``hermes_cli/gateway.py::_builtin_setup_fn``.
* Remove the entire 32-line ``_PLATFORMS["discord"]`` static dict entry —
Discord's setup metadata is now discovered dynamically via
``_all_platforms()`` from the registry entry.
* Move the 59-line ``discord_cfg`` YAML→env bridge from
``gateway/config.py::load_gateway_config()`` into the plugin as
``_apply_yaml_config``. Covers ``require_mention``,
``thread_require_mention``, ``free_response_channels``, ``auto_thread``,
``reactions``, ``ignored_channels``, ``allowed_channels``,
``no_thread_channels``, ``allow_mentions.{everyone,roles,users,
replied_user}``, and ``reply_to_mode`` (including the YAML 1.1
``off``-as-False coercion and the ``extra.reply_to_mode`` fallback).
* Wire via ``apply_yaml_config_fn=_apply_yaml_config``.
* The hook runs BEFORE ``_apply_env_overrides`` and after the generic
shared-key loop, exactly as documented in
``website/docs/developer-guide/adding-platform-adapters.md``.
* Behavior is preserved exactly — every assignment still uses
``not os.getenv(...)`` guards so env vars take precedence over YAML.
All 78 references to the old import path are rewritten — no back-compat
shim:
* 51 ``from gateway.platforms.discord import X`` →
``from plugins.platforms.discord.adapter import X``
* 5 ``import gateway.platforms.discord as discord_platform`` →
``import plugins.platforms.discord.adapter as discord_platform``
* 1 ``from gateway.platforms import discord as discord_mod`` →
``from plugins.platforms.discord import adapter as discord_mod``
* 21 ``mock.patch("gateway.platforms.discord.X")`` strings →
``mock.patch("plugins.platforms.discord.adapter.X")``
* 1 docstring reference in ``hermes_cli/commands.py``
* 1 import in ``tools/send_message_tool.py`` (now removed entirely)
The import-safety test in ``tests/gateway/test_discord_imports.py`` is
updated to purge the new canonical module name from ``sys.modules``.
**38 files changed, +621 / −473** — net positive due to the YAML hook
implementation (89 new LOC in the plugin trading for 59 deleted in core),
but every line moved has a clear plugin home now. The git rename is
detected at R090 because the adapter gained ~340 LOC of moved-in hook
implementations (``_standalone_send`` + ``interactive_setup`` +
``_apply_yaml_config`` + helpers).
* All 568 Discord-specific tests pass across 25 ``test_discord_*.py``
files plus voice/send/text-batching/reload-skills/stream-consumer/
integration tests.
* All 147 tests in the YAML-touching subset
(``test_discord_reply_mode``, ``test_discord_free_response``,
``test_discord_allowed_channels``, ``test_discord_allowed_mentions``,
``test_discord_channel_controls``, ``test_discord_reactions``,
``test_discord_thread_persistence``, ``test_runtime_footer``) pass —
this is the strongest signal that the YAML→env hook behaves
identically to the legacy block.
* Broader gateway/cron/integration sweep (1297 tests) introduces zero
new failures vs ``main``. Pre-existing failures in
``tests/gateway/test_tts_media_routing.py`` and
``tests/e2e/test_platform_commands.py`` reproduce identically on the
unchanged ``main`` revision.
* Plugin discovery sanity check confirms Discord registers alongside the
other four platform plugins:
Registered platforms: ['discord', 'google_chat', 'irc', 'line', 'teams']
These Discord-shaped tendrils in core were **deliberately not moved** —
they are generic platform-registry concerns affecting every platform,
not Discord-specific:
* ``gateway/config.py:1205`` ``DISCORD_BOT_TOKEN → config.token`` env
enablement — same shape Telegram has. The existing
``env_enablement_fn`` registry hook only seeds ``extra``, not
``.token``, so it can't replace this without an adapter refactor to
read from ``extra["bot_token"]``.
* ``gateway/run.py`` voice-mode hooks
(``self.adapters.get(Platform.DISCORD)`` for
``start_voice_mode``/``stop_voice_mode``), role-based auth,
``DISCORD_ALLOW_BOTS`` branch in ``_is_user_authorized``,
``_UPDATE_ALLOWED_PLATFORMS`` frozenset, and the per-platform
allowlist maps — generic platform-registry concerns.
* ``Platform.DISCORD`` enum literal — stable identifier used as dict
keys throughout the codebase; removing it is a separate refactor with
no real benefit.
* ``tools/discord_tool.py`` and ``tools/environments/local.py`` —
first-class agent tools and env-passthrough config, neither is the
gateway adapter.
Each of these is worth its own scoping issue when the time comes.
Mirrors the architecture established by the web (#25182), browser
(#25214), and video_gen (#25126) plugin migrations:
* `tools/fal_common.py` — stateless atoms shared by both FAL-backed
plugins (image_gen + video_gen). Holds the lazy `fal_client` import
helper, `_ManagedFalSyncClient`, `_normalize_fal_queue_url_format`,
`_extract_http_status`. Stateful pieces (`fal_client` module global,
`_managed_fal_client*` cache, `_submit_fal_request`,
`_resolve_managed_fal_gateway`, `_get_managed_fal_client`)
intentionally stay on `tools.image_generation_tool` so the existing
`monkeypatch.setattr(image_tool, ...)` patch sites keep working
unchanged.
* `plugins/video_gen/fal/__init__.py` — drops its inline
`_load_fal_client` duplicate; consumes `tools.fal_common.import_fal_client`.
* `plugins/image_gen/fal/{plugin.yaml,__init__.py}` — new plugin.
`FalImageGenProvider` is a thin registration adapter that resolves
the legacy module via `import tools.image_generation_tool as _it`
and calls `_it.image_generate_tool` + `_it._resolve_fal_model` at
call time. The 18-model catalog, `_build_fal_payload`, managed-
gateway selection, and Clarity Upscaler chaining all remain in
`tools.image_generation_tool` as the single source of truth —
the plugin is a registration adapter, not a parallel implementation.
* `tools/image_generation_tool.py::_dispatch_to_plugin_provider` —
drops the `configured == "fal"` skip. Setting `image_gen.provider:
fal` now routes through the registry like any other provider; the
plugin re-enters this module's pipeline so behavior is identical.
Unset `image_gen.provider` still falls through to the in-tree
pipeline (preserves no-config-with-FAL_KEY UX from #15696).
* `hermes_cli/tools_config.py` — drops the hardcoded "FAL.ai" row from
`TOOL_CATEGORIES["image_gen"]["providers"]` (now injected by
`_plugin_image_gen_providers` like every other backend) and the
`getattr(provider, "name") == "fal"` skip that protected against
duplication with the hardcoded row. The "Nous Subscription" row
stays as a setup-flow entry — same shape browser kept "Nous
Subscription (Browser Use cloud)" after #25214.
* `tests/plugins/image_gen/test_fal_provider.py` — 14 cases covering
the ABC surface, call-time indirection (verifying
`monkeypatch.setattr(image_tool, "image_generate_tool", ...)` takes
effect through the plugin), response-shape stamping, exception
handling, and registry wiring.
* `tests/plugins/image_gen/check_parity_vs_main.py` — subprocess
harness mirroring `tests/plugins/browser/check_parity_vs_main.py`.
Pins one path to origin/main, one to the worktree; runs six
scenarios (unset, explicit-fal-no-creds, explicit-fal-with-creds,
explicit-fal-with-model, typo provider, managed-gateway-only) and
diffs the reduced shape `{dispatch_kind, provider_name, model}`
per scenario. The only acceptable diff is "legacy_fal → plugin
(fal)" for explicit-FAL paths — every other delta is flagged as
a regression.
* `tests/hermes_cli/test_image_gen_picker.py::test_fal_surfaced_alongside_other_plugins`
— flips the previous `test_fal_skipped_to_avoid_duplicate` to
match the new shape (FAL is a plugin now, no dedup needed).
Verified: 195/195 tests across
`tests/{tools/test_image_generation*,tools/test_managed_media_gateways,plugins/image_gen,plugins/video_gen,hermes_cli/test_image_gen_picker}.py`
pass on this branch with no test patches modified outside the picker
test that asserted the old skip behaviour.
Fixes#26241
_maybe_follow_capture() issued a follow-up screenshot unconditionally
when capture_after=True, even when res.ok=False. The model then received
a normal-looking screenshot alongside an error message, and in practice
it often ignored ok=False and proceeded as if the action had succeeded.
Fix: return _text_response(res) early when res.ok is False so the model
receives only the error and can decide how to recover.
Tests added:
- test_capture_after_skipped_when_action_failed: patches click to return
ok=False and asserts no capture call is issued.
- test_capture_after_fires_when_action_succeeds: ensures the happy path
still triggers the follow-up capture.
_dispatch() routes action="set_value" to backend.set_value(), but:
- ComputerUseBackend did not declare set_value as @abstractmethod, so
subclasses could silently omit it without a TypeError at class load time.
- _NoopBackend (the test/CI stub) had no set_value method at all, causing
AttributeError in any test that exercises the set_value action path.
Fix:
- Add set_value as @abstractmethod to ComputerUseBackend in backend.py.
- Add a recording stub in _NoopBackend in tool.py.
- Add two TestDispatch cases: one verifying the call reaches the backend,
one verifying the missing-value guard returns a clean error.
The ensure('stt.faster_whisper') lazy-install mechanism was defined in
lazy_deps.py but never called from the STT code path. When
_HAS_FASTER_WHISPER (a module-level constant) evaluated to False at
import time, _get_provider() returned 'none' immediately without
attempting installation. On fresh container builds or venv recreations,
this meant voice message transcription broke silently until someone
manually installed faster-whisper.
Add _try_lazy_install_stt() helper that calls ensure() and
re-checks dynamically via importlib.util.find_spec. Wire it into
all three gates in transcription_tools.py:
- _get_provider() explicit 'local' path (line 221)
- _get_provider() auto-detect path (line 287)
- _transcribe_local() guard (line 405)
This ensures the first voice message after any fresh install triggers
auto-installation instead of failing permanently until a process restart.
The cherry-pick of #22891 (max_elements cap) reshuffled _capture_response
so summary was assigned inside both the multimodal and AX branches,
but #30126's aux-vision routing call (_route_capture_through_aux_vision)
fires BEFORE either branch and references the not-yet-bound name.
Compute summary once up-front, keep the AX-branch rebuild for the
truncation note.
Four findings from Copilot's review on PR #22891, all in the AX
elements-array cap added by 22fa1ed:
1. The truncation note ("response truncated to N of M elements") was
appended unconditionally — including in the som/vision multimodal
path, whose response carries a screenshot rather than an `elements`
array. The note described a payload field that wasn't present.
Moved the note into the AX-text branch where the array actually
appears.
2. `_format_elements(cap.elements)` ran on the full untrimmed list with
its own `max_lines=40` cap, so a caller passing `max_elements=10`
would see summary lines referencing `#11..#40` even though the JSON
`elements` array only held #1..#10. Format on `visible_elements`
instead so the summary indices always exist in the response.
3. `_coerce_max_elements` enforced a lower bound but no upper bound,
so `max_elements=10_000_000` silently disabled the safeguard and
reintroduced the original context-blow-up. Added a hard cap
(`_MAX_ALLOWED_MAX_ELEMENTS = 1000`) that clamps oversized values.
4. The schema string said "Default 100" but the property carried no
`default` field, and claimed `max_elements` had no effect on som/
vision while the image-missing fallback path can still return an
elements array. Added `"default": 100`, `"maximum": 1000`, and
clarified the fallback-path wording.
Each finding gets a regression test:
- test_capture_ax_clamps_oversized_max_elements_to_hard_cap
- test_capture_ax_summary_indices_match_returned_elements
- test_capture_multimodal_summary_omits_truncation_note
- test_schema_max_elements_documents_default_and_upper_bound
Verified with `pytest tests/tools/test_computer_use.py` (53 passed,
including the 5 new cases). Confirmed each new test fails on the
pre-fix code path before applying the production change.

`computer_use(action='capture', mode='ax')` returned the full AX element
list verbatim in the JSON response. Dense Electron / Obsidian / JetBrains
UIs publish 500+ AX nodes (one reproduction in #22865 returned 597
elements against Obsidian), so a single capture could consume enough
context to trigger compression failures or render the session unusable.
The human-readable `_format_elements` summary is already capped at 40
lines, so the truncation gap was invisible to anyone reading the summary
output.
Add a `max_elements` argument to the tool schema, default 100, that
trims the AX `elements` array. When the cap fires, the response surfaces
`total_elements` and `truncated_elements` and appends a "raise
max_elements or pass app= to narrow" hint to the summary so the model
knows the JSON view is partial and can re-issue with a tighter scope.
Validation is centralized in `_coerce_max_elements`: missing /
non-integer / sub-1 inputs fall back to the default cap, so the
protection can never be silently disabled by a malformed tool-call
argument. The cap only affects AX-mode JSON; `mode='som'` and
`mode='vision'` keep returning a screenshot + image-aware summary
unchanged.

When the active main model has no vision capability — or when the user
explicitly configured auxiliary.vision in config.yaml — sending the
captured screenshot back to the main model in a multimodal tool-result
envelope is the wrong move: it trips HTTP 404 / 400 at the provider
boundary (e.g. 'No endpoints found that support image input') and the
agent loop reports a hard tool failure for what should have been a
simple capture.
The reporter on #24015 hit this with:
model:
default: tencent/hy3-preview # no vision support
provider: openrouter
auxiliary:
vision:
provider: openrouter
model: google/gemini-2.5-flash # explicitly configured
…and observed:
computer_use(action='capture', mode='som')
→ ⚠️ API call failed (attempt1/3): NotFoundError [HTTP 404]
🔌 Provider: openrouter Model: tencent/hy3-preview
📝 Error: HTTP 404: No endpoints found that support image input
Fix: in tools/computer_use/tool.py::_capture_response, after a
screenshot is captured (modes 'som' / 'vision'), consult the routing
helper introduced earlier in this branch. When it says 'route to aux',
materialise the PNG to $HERMES_HOME/cache/vision/, run vision_analyze
on it (which honours auxiliary.vision via the standard async_call_llm
task='vision' router), and return a text-only JSON tool result that
embeds the analysis alongside the existing AX/SOM index. The main
model never sees the pixels — it sees an actionable text description
plus the same set-of-mark element index it normally uses.
The two new helpers (_should_route_through_aux_vision,
_route_capture_through_aux_vision) keep the policy and the IO
separated so each can be tested in isolation. Both fail open: if the
config import fails, if the aux call raises, or if the analysis is
empty, we fall back to the existing multimodal envelope so the
behaviour is at worst the pre-fix status quo. Temp screenshot files
are cleaned up unconditionally in a finally block — even on aux call
failure — to avoid leaving residue under cache/vision/.
The end-to-end regression for #24015 is added in the next commit.
Add tools/computer_use/vision_routing.py with
should_route_capture_to_aux_vision(provider, model, cfg) — a small
policy helper that decides whether a captured screenshot should be
returned as a multimodal envelope (main model has native vision) or
pre-analysed through the auxiliary.vision pipeline so the main model
only sees text.
The decision mirrors agent.image_routing.decide_image_input_mode for
user-attached images, so the capture path and the user-turn path agree
on what counts as an explicit aux vision override:
* provider/model/base_url under auxiliary.vision => explicit override
=> route through aux vision
* provider+model accepts multimodal tool results AND main model
reports supports_vision=True => keep multimodal envelope
* everything else (no tool-result image support, non-vision model,
metadata lookup failure) => fail closed and route through aux
No call sites are changed in this commit; the helper is added in
isolation so the routing decision can be unit-tested before it is
plumbed into _capture_response().
`CuaDriverBackend.capture(app=X)` and `focus_app(app=X)` silently fell back
to the frontmost on-screen window when X matched no app — typically a
menu-bar utility (e.g. "Fuwari" in the bug reporter's case) rather than
the requested app. The agent then received UI elements for the wrong app
and clicked / typed into it.
The root cause is a localized macOS app name mismatch: `list_windows`
returns the localized `app_name` (e.g. "計算機" on a Japanese/Chinese
system) but callers naturally pass the English name ("Calculator"). The
substring filter doesn't match, and the code falls through to picking the
frontmost window with no signal that the filter was effectively dropped.
Fix:
- `capture(app=…)`: when the filter matches nothing, return a
`CaptureResult` with empty `app`/`elements` and a diagnostic
`window_title` pointing the caller at `list_apps` and noting the
localized-name convention. `_active_pid` / `_active_window_id` are left
untouched so a subsequent action doesn't inadvertently hit the wrong
process.
- `focus_app(app=…)`: when the filter matches nothing, set `target = None`
and let the existing `return ActionResult(ok=False, …, "No on-screen
window found for app …")` path fire instead of falsely reporting success
on the frontmost window.
This addresses bug 1 only from #24170. Bugs 2 & 5 are addressed in #30046;
bugs 3 & 4 in #30032.
Bug 2 (capture_after=True loses app context):
_maybe_follow_capture called backend.capture(mode='som') with no app=,
causing cua-driver to capture the frontmost window instead of the app
targeted by the preceding capture/focus_app. Fix: track _last_app on
CuaDriverBackend and thread it through the follow-up capture call so
the same app is re-captured regardless of which window has OS focus.
Bug 5 (element labels stripped in capture results):
_ELEMENT_LINE_RE matched the classic ' - [N] AXRole "label"' format
but not the '[N] AXRole (order) id=Label' format introduced in
cua-driver v0.1.6. All element labels were silently dropped as empty
strings, making element identification impossible.
Fix: extend regex to capture both group(3) (quoted label) and group(4)
(id= label), and update _parse_elements_from_tree to use group(4) as
fallback. Both old and new cua-driver output now produce populated
UIElement.label values.
focus_app() now also sets _last_app so that capture_after= on any
subsequent action re-targets the focused app.
5 new regression tests added.
Part of #24170 (bugs 1 and 3/4 addressed separately).
* fix(skills): skip dependency dirs in skill scan
* fix(skills): widen sibling rglob scanners to use shared exclusion set
Follow-up to PR #29968. The contributor's PR widened EXCLUDED_SKILL_DIRS
in the canonical walker (iter_skill_index_files), which fixes the
user-visible discovery path. This commit sweeps the ~12 other
rglob('SKILL.md') sites that did their own ad-hoc filtering — most only
checked .git/.hub, some had no filter at all — so dependency dirs
(.venv, node_modules, site-packages, etc.) cannot leak ghost skills
through the secondary paths.
Adds agent.skill_utils.is_excluded_skill_path(path) helper. Migrates
all 13 sites to use it. Removes 3 hardcoded duplicate filter sets.
Sites touched:
agent/curator_backup.py - skill backup file count
gateway/run.py - disabled-skill response (2 sites)
hermes_cli/dump.py - skill count in env dump
hermes_cli/profile_describer.py- profile description (2 sites)
hermes_cli/profile_distribution.py - profile install count
hermes_cli/profiles.py - profile skill count
hermes_cli/skills_hub.py - category detection
tools/skill_manager_tool.py - skill name lookup (already used set, now uses helper)
tools/skill_usage.py - usage tracking + skill dir lookup (2 sites)
tools/skills_hub.py - optional skills find + scan (2 sites)
tools/skills_sync.py - bundled skills sync
E2E verified with the exact reported shape
(bring/scripts/.venv/.../typer/.agents/skills/typer/SKILL.md): no
sibling site picks up the ghost skill, all five legit-skill counts
still return 1.

Bug 3: The cua_backend type_text() method called MCP tool 'type_text_chars'
which does not exist in current cua-driver. Changed to 'type_text' which is
the correct MCP tool name.
Bug 4: The drag() method returned a hardcoded 'not supported' error even
though cua-driver exposes a 'drag' MCP tool. Implemented proper drag
dispatching with coordinate-based and element-based targeting.
Added dispatch-level validation for drag to ensure from/to coordinates
or elements are provided before calling any backend.
Fixes#24170 (bugs 3 and 4)
Five call sites do os.chmod(path.parent, 0o700) without checking that
the parent resolves to a safe directory. If HERMES_HOME or another
path env var resolves to /, the chmod strips traversal permission from
the root inode and bricks the entire host.
Add secure_parent_dir() to hermes_constants.py that refuses to chmod
/ or any top-level directory (depth < 2). Replace all 5 call sites
with this helper.
Fixes#25821
Sibling fix on top of @EloquentBrush0x's PR #29441.
- tools/skills_hub.py GitHubSource.search() had the same r.name dedup bug.
Two configured GitHub taps publishing same-named skills would collapse to one.
- tests/hermes_cli/test_skills_hub.py:test_browse_skills_dedup_uses_identifier_not_name
patched hermes_cli.skills_hub.create_source_router, but browse_skills() imports
it locally from tools.skills_hub. Fixed patch path.
Browse.sh exposes skills by task name (e.g. "search-listings"), which is
shared across hundreds of sites. Deduplicating by name silently dropped
every browse-sh skill after the first one with a given task name — e.g.
only Airbnb's "search-listings" would survive, collapsing Booking.com,
Zillow, and every other site's variant into nothing.
Switch unified_search() and do_browse() to use r.identifier as the dedup
key. identifier is always globally unique (e.g.
"browse-sh/airbnb.com/search-listings-ddgioa"), so same-named skills from
different browse-sh hostnames are preserved as distinct results.
Update existing TestUnifiedSearchDedup tests to model the real scenario
(same identifier appearing from two sources) and add a regression test
that asserts browse-sh skills with the same name but different hostnames
are never collapsed.
The xAI Responses API for x_search returns 200 OK with a
synthesized fluff answer in two failure modes that callers currently
cannot distinguish from a real, citation-backed result:
1. Any narrowing filter (allowed_x_handles, excluded_x_handles,
from_date, to_date) was active, but the X index returned no
matching posts. The model then answers from training data.
2. The date range is malformed, inverted, or pure-future (e.g.
from_date=2030-01-01). The API call burns quota and Grok
responds with a generic answer.
Mitigations, both client-side:
* Validate from_date / to_date before the HTTP call:
- Strict YYYY-MM-DD.
- from_date <= to_date when both set.
- from_date <= today UTC (no posts in a window that hasn't
started). to_date in the future remains allowed so callers
can request 'from yesterday to tomorrow'.
* Add 'degraded' + 'degraded_reason' to successful responses.
degraded=True iff any narrowing filter was active AND both the
top-level 'citations' array and inline 'url_citation'
annotations came back empty. A broad query with no filters that
returns no citations is *not* flagged degraded — that case is
just an unsourced answer, not a filter miss.
Tests cover all four validation paths plus six degraded-flag
scenarios (each filter type, inline vs top-level citation
recovery, broad query baseline). All existing tests continue to
pass; the additions are purely additive on the success-path
response shape.
Discovered while testing the x_search toolset end-to-end:
queries scoped to @Teknium1 returned confident-sounding generic
text about Nous Research with zero citations, and from_date in
2030 produced sassy non-answers. Both are now detectable by the
caller.
* fix(lint): skip per-file shell linter when LSP will handle the file
`_check_lint` ran `npx tsc --noEmit FILE.ts` after every `.ts`/`.tsx`
edit. `tsc` ignores `tsconfig.json` when given an explicit file argument
(documented quirk) and defaults to no-lib / ES5, so every ES2015+ stdlib
reference reports as missing:
- `Cannot find global value 'Promise'`
- `Cannot find name 'Map' / 'Set' / 'ReadonlySet' / 'Iterable'`
- `Property 'isFinite' does not exist on type 'NumberConstructor'`
- `Module 'phaser' can only be default-imported using esModuleInterop`
- `import.meta is only allowed when --module is es2020+`
On real TypeScript projects this floods the `lint` field on
WriteResult / PatchResult with up to 25K tokens of false positives
per edit. The delta filter in `_check_lint_delta` is supposed to mask
them, but a tiny edit shifts line numbers and every phantom resurfaces
as "introduced by this edit". The result is a 1MB+ phantom-error dump
on every patch that eats the agent's context budget. Same shape for
`.go` (`go vet` outside a module) and `.rs` (`rustfmt --check` outside
a Cargo project).
PR #24168 added an LSP tier on top of this — real `tsserver` / `gopls`
/ `rust-analyzer` diagnostics surface in the separate `lsp_diagnostics`
field. But the broken shell linter kept running underneath, so the
phantom-error dump kept happening even when LSP was giving us a clean
authoritative signal.
This change short-circuits the shell linter for the structurally-broken
extensions (`.ts`, `.tsx`, `.go`, `.rs`) when an LSP server is active
and claims the file via `LSPService.enabled_for(path)`. The LSP tier
runs as before and carries the real diagnostics in `lsp_diagnostics`.
Other shell linters (`py_compile`, `node --check`) keep running
unconditionally — they're fast, file-local, and correct.
Default behavior (LSP disabled, LSP misconfigured, remote backend, file
outside a workspace) is unchanged — the existing fallback paths trigger
when `_lsp_will_handle` returns False, so users who haven't opted into
LSP get the same shell-linter behavior they had before.
Drive-by: `.tsx` was missing from the `LINTERS` table entirely, so TS
React files got no post-edit syntax check at all. Added it for
symmetry; in practice it now hits the LSP-skip path.
Tests:
- `tests/agent/lsp/test_shell_linter_lsp_skip.py` — 14 tests covering:
* skip happens for each redundant extension when LSP claims the file
(asserted by patching `_exec` to raise on any shell-linter call)
* shell linter still runs when LSP is inactive (regression guard)
* `.py` / `.js` continue to run unconditionally even with LSP active
* `_lsp_will_handle` is exception-safe: returns False on None
service, remote backend, or `enabled_for` raising
* `.tsx` is in both `LINTERS` and `_SHELL_LINTER_LSP_REDUNDANT`
- All pre-existing tests in `tests/agent/lsp/` and
`tests/tools/test_file_operations*.py` still pass (233/233).
* fix(lint): address Copilot review on #29054
Two fixes from copilot-pull-request-reviewer on PR #29054:
1. `.tsx` regression with LSP disabled
(https://github.com/NousResearch/hermes-agent/pull/29054#discussion_r3271017282)
The first revision added `.tsx` to the `LINTERS` table so that
TypeScript React files would hit the LSP skip path. Side effect:
when LSP is *disabled* (the default), `.tsx` edits would suddenly
run `npx tsc --noEmit FILE.tsx` and inherit the same phantom-error
dump this PR is supposed to fix. Pre-PR behavior was implicit
`skipped` (no `LINTERS` entry); restore that.
- Remove `.tsx` from `LINTERS`.
- Remove `.tsx` from `_SHELL_LINTER_LSP_REDUNDANT` (the skip path
is unreachable without a `LINTERS` entry — falls through to
`ext not in LINTERS` first).
- When LSP IS enabled, `.tsx` is still covered by the LSP tier
via `_maybe_lsp_diagnostics` (typescript-language-server's
`extensions` tuple includes `.tsx`), so the diagnostics still
surface — just on the `lsp_diagnostics` channel, not `lint`.
- Update test_shell_linter_lsp_skip.py to reflect this contract
(drop `.tsx` from the parametrize lists; add
`test_tsx_stays_out_of_linters_table_for_default_compatibility`
and `test_tsx_default_check_lint_returns_skipped`).
2. V4A patches dropped `WriteResult.lsp_diagnostics`
(https://github.com/NousResearch/hermes-agent/pull/29054#discussion_r3271017295)
`tools/patch_parser.py::apply_v4a_operations` calls
`file_ops.write_file()` per operation, then calls `_check_lint()`
directly afterwards — but never propagates `WriteResult.lsp_diagnostics`
to the `PatchResult`. The shell-linter skip introduced in this PR
makes the gap visible: a `.ts` / `.go` / `.rs` V4A patch with LSP
active would return `lint = {f: {skipped: True}}` and zero
diagnostics from any channel.
- `_apply_add` and `_apply_update` now return
`Tuple[bool, str, Optional[str]]` where the third element is
`WriteResult.lsp_diagnostics` (or `None` on failure / no diags).
- `_apply_delete` and `_apply_move` stay 2-tuples — they don't
produce diagnostics, no write goes through `write_file`.
- `apply_v4a_operations` accumulates per-file diagnostics blocks
and surfaces a combined block on `PatchResult.lsp_diagnostics`.
Each block already carries its `<diagnostics file="...">` header
from `LSPService.report_for_file`, so concatenation preserves
per-file attribution.
Tests added (`test_patch_parser.py::TestV4ALspDiagnosticsPropagation`):
- ADD op: `WriteResult.lsp_diagnostics` flows to `PatchResult`
- UPDATE op: same
- No diagnostics → `PatchResult.lsp_diagnostics is None` (not "")
- Multi-file patch: combined block contains every per-file block
Verification:
- Targeted test scope: 257/257 pass
(tests/agent/lsp/, tests/tools/test_file_operations*.py,
tests/tools/test_patch_parser.py)
- Wider sweep: 5400 pass; 11 failures all pre-existing on origin/main
(file_staleness / file_read_guards / file_state_registry — unrelated
macOS /var/folders tmp-path sensitivity issues, confirmed by
re-running on a clean origin/main checkout)
* docs(test): align shell-linter LSP skip docstring with .tsx behavior
Copilot review feedback (review #4324947616, comment #3271049036):
the test module docstring still listed .tsx alongside .ts/.go/.rs in
the skip contract, but .tsx is now intentionally NOT in LINTERS or
_SHELL_LINTER_LSP_REDUNDANT. Updated the bullet list to drop .tsx from
the skip contract and added a paragraph documenting why .tsx is left
out (preserves pre-PR implicit-skip behavior for LSP-disabled users;
LSP coverage still happens via _maybe_lsp_diagnostics).
* test(lsp): drop unused tmp_path from _make_fops helper
Copilot review #3271069484: the helper accepted tmp_path but never
used it. Callers still need tmp_path themselves for the file they're
asserting against, so we just drop the helper's parameter.

Commits 8bf09455d (Grogger, explicit creationflags=) and 95683c028
(nekwo, **_popen_kwargs via windows_hide_flags()) landed 77 minutes
apart and both injected creationflags into the same subprocess.Popen
call. nekwo's commit correctly replaced the explicit line in
tools/process_registry.py but only added the kwargs spread in
tools/environments/local.py -- leaving creationflags specified twice.
Result on Windows: every LocalEnvironment.init_session() raised
"subprocess.Popen() got multiple values for keyword argument
'creationflags'" and fell back to bash -l per command (much slower --
bashrc runs on every shell invocation).
Drop the explicit line so **_popen_kwargs is the single source.
`_wait_for_process()` was sleeping for a fixed 200ms between polls of
the subprocess exit status. For commands that complete in <50ms (echo,
pwd, date, cat short files, write_file with small content, read_file
with small content), the agent was stuck waiting for the next 200ms
tick to notice the process had exited. That floor was the dominant
component of per-tool latency for typical short commands.
Replace with adaptive backoff: start at 5ms, multiply by 1.5 each
iteration up to 200ms. Fast commands (the common case) return in
~6ms; long-running commands (builds, tests, sleeps) reach the 200ms
steady-state poll rate within ~12 iterations (~150ms total) and pay
identical CPU after that.
Tool-call wall time (deterministic microbench of `echo first`):
before: median 200ms min 200ms max 200ms
after: median 5ms min 5ms max 7ms
saved: ~195ms per terminal tool call
End-to-end chat -q with 3 sequential terminal tool calls
(`echo first`, `echo second`, `echo third`):
before: median 5.73s, min 5.61s
after: median 4.64s, min 4.60s
saved: ~1100ms wall per turn
Live tmux session: a typical 'write file, read it back' turn now
displays each tool as 0.1s in the spinner (was 0.9s before). The
agent observes the subprocess exit ~200ms faster per call. For chat
workflows that do 4-8 terminal/file calls per turn this saves
800ms-1.5s of pure wall-clock waiting.
Why it's safe:
- Interrupt and timeout checks still fire on every iteration (no
longer rate-limited to 5/sec)
- Activity callback fires on the same 'due' schedule (`touch_activity_if_due`)
- DEBUG_INTERRUPT heartbeat is unchanged (30s)
- Steady-state poll rate for long-running commands matches the old
200ms within ~150ms of startup
Tests:
- tests/tools/ — 5246 passed, 22 skipped, 2 pre-existing xdist flakes
(test_delegate.py::test_depth_limit, test_constants — pass in isolation)
- Live tmux: 2-turn conversation + multiple tool calls, no errors
Adds a new bundled web search provider plugin backed by xAI's agentic
Web Search tool (server-side `web_search` on the Responses API). Slots
in alongside the existing Firecrawl / Tavily / Exa / Brave / SearXNG /
DDGS providers; opt in via `web.backend: xai` (or auto-selected by the
registry's single-provider shortcut when it's the only available web
provider, matching every other backend's behavior).
Reuses the existing xAI HTTP credential plumbing (`tools/xai_http.py`)
so it works with both `hermes auth login xai-oauth` (SuperGrok OAuth)
and `XAI_API_KEY` — no new credential paths, no new env vars, no new
setup-wizard prompts. The existing `xai_grok` post_setup hook handles
credential collection.
Reference: https://docs.x.ai/developers/tools/web-search
Provider behavior
-----------------
- Sends a structured prompt to Grok with `tools=[{"type": "web_search"}]`
enabled and `include=["no_inline_citations"]`, then parses results
from a `{"results": [...]}` JSON block (primary), falling back to
`url_citation` annotations (secondary) and the top-level `citations`
list (last-ditch). Annotation fallback falls through to citations
when no rows are extractable, so future annotation types xAI may
add don't silently mask real data.
- HTTP 200 + `{"error": {...}}` envelopes (model-overload, refusal)
are surfaced as failures rather than masked as success-with-empty-
results.
- HTTP 401 on the OAuth path triggers a single `force_refresh=True`
retry — closes two gaps the resolver's proactive JWT-exp shortcut
doesn't cover: opaque (non-JWT) access tokens and mid-window
revocation. Env-var (`XAI_API_KEY`) credentials never retry; they
can't be refreshed and an immediate retry would just burn quota.
- `is_available()` is a cheap probe (env var OR auth.json read), never
invokes the OAuth resolver — required by the ABC contract because
it runs on every `hermes tools` repaint and at tool-registration time.
- Class docstring documents the LLM-in-a-trench-coat trust model so
callers piping untrusted input into `web_search` know returned URLs
are model-generated and should be validated before fetching.
Config (`config.yaml`):
web:
backend: xai

allowed_domains: # optional, max 5 — mutex with excluded_domains

Apply Windows CREATE_NO_WINDOW flags to foreground local terminal subprocesses and tracked background processes so Hermes operations do not flash or steal focus with extra console windows.
When 'hermes update' syncs bundled skills, the summary line only shows
the count of user-modified skills that were kept (e.g. '3 user-modified
(kept)'), but not *which* skills. Once the update finishes, the user
has no way to know which skills need triage.
Append the skill names to the summary line, truncated to 5 with a
'+N more' suffix for long lists:
Done: 12 new, 3 updated, 7 unchanged, 3 user-modified (kept):
hermes-agent, debugging-hermes-tui-commands, system-health.
25 total bundled.
Closes#28121
Sweep of all CI failures on origin/main, grouped by drift source:
Telegram allowlist gate (db50af910 added user-authz to _should_process_message):
- Hardcoded "[Telegram]" prefix in the logger.warning so the call no
longer dereferences self.name → self.platform, which test fixtures
built via object.__new__ never set.
- test_telegram_format / test_allowed_channels_widening fixtures stub
_is_callback_user_authorized → True so the new gate doesn't reject
guest-mode / allowed-channels test messages.
- test_telegram_approval_buttons::test_update_prompt_callback_not_affected
sets TELEGRAM_ALLOWED_USERS="*" so the fail-closed default doesn't
reject the callback before it writes .update_response.
Approval surface (6d495d9e7 renamed status, 214b95392 detached stdin):
- test_no_callback_returns_approval_required: status is now
"pending_approval" (was "approval_required").
- test_close_stdin_allows_eof_driven_process_to_finish: switch to
use_pty=True; non-PTY now uses stdin=DEVNULL.
Mattermost (send() now resolves root_id via _api_get first):
- test_send_with_thread_reply mocks _session.get with a thread-root
response so the new resolver doesn't TypeError on a bare AsyncMock.
Kanban (d8ad431de rename, f55d94a1e review column, _kanban_worker_skill_available):
- _safe_int → _to_epoch in the two test_kanban_db tests.
- Spawn-skills tests (×3) monkey-patch _kanban_worker_skill_available
to True since the isolated kanban_home fixture has no devops/kanban-worker tree.
- test_gateway_dispatcher_disables_corrupt_board: connect count
3 → 5 (review-column probe now also runs per tick).
Aux-config severity at_or_above (a94ddd807):
- test_diagnostics_endpoint_severity_filter expects warning filter to
include error+critical now (was exact-match).
Anthropic error handling (conversation loop extracted from run_agent):
- _no_backoff_wait fixture patches BOTH run_agent.jittered_backoff AND
agent.conversation_loop.jittered_backoff. The latter is the actual
call site; without the second patch tests burn ~2s per retry and
hit the 30s SIGALRM timeout on CI.
Other test pollution / drift:
- test_auto_does_not_select_copilot_from_github_token: patch
agent.bedrock_adapter.has_aws_credentials → False so boto3's
credential chain can't auto-pick Bedrock from developer ~/.aws.
- test_setup_openclaw_migration: patch hermes_cli.gateway.get_env_value
in addition to setup_mod.get_env_value — _platform_status reads
through the gateway module's binding.
- test_gateway_prefix: COMPONENT_PREFIXES["gateway"] now includes
"hermes_plugins" too.
- test_recommended_update_command_defaults_to_hermes_update: also
short-circuit get_managed_update_command in case a stray
~/.hermes/.managed marker is present.
- test_user_id_is_not_explicit: _parse_target_ref now returns
is_explicit=False for Slack U.../W... IDs (chat.postMessage rejects
them — a DM must be opened first via conversations.open).
1. trajectory_compressor.py: yaml.safe_load() returns None on empty
files, crashing with TypeError on `if 'tokenizer' in data`. Fix by
adding `or {}` fallback. (HIGH — blocks startup with empty config)
2. 6 files with fcntl.flock(LOCK_UN) in finally blocks without
try/except: cron/scheduler.py, hermes_cli/auth.py,
agent/shell_hooks.py, tools/skill_usage.py,
tools/environments/file_sync.py, tools/memory_tool.py. If unlock
raises OSError, fd.close() is skipped and the lock is held forever.
The msvcrt branches already had try/except; the fcntl branches did
not. Fix by wrapping in try/except (OSError, IOError): pass.
3. agent/copilot_acp_client.py line 639: TOCTOU race — path.exists()
followed by path.read_text() with no try/except. If file is deleted
between the check and the read, FileNotFoundError propagates. Fix
by using try/except FileNotFoundError.
4. gateway/sticker_cache.py: non-atomic write via Path.write_text()
can leave truncated JSON on crash, causing JSONDecodeError on next
load. Fix by writing to tempfile + fsync + os.replace (atomic).
