Adds a new authentication provider that lets SuperGrok subscribers sign
in to Hermes with their xAI account via the standard OAuth 2.0 PKCE
loopback flow, instead of pasting a raw API key from console.x.ai.
Highlights
----------
* OAuth 2.0 PKCE loopback login against accounts.x.ai with discovery,
state/nonce, and a strict CORS-origin allowlist on the callback.
* Authorize URL carries `plan=generic` (required for non-allowlisted
loopback clients) and `referrer=hermes-agent` for best-effort
attribution in xAI's OAuth server logs.
* Token storage in `auth.json` with file-locked atomic writes; JWT
`exp`-based expiry detection with skew; refresh-token rotation
synced both ways between the singleton store and the credential
pool so multi-process / multi-profile setups don't tear each other's
refresh tokens.
* Reactive 401 retry: on a 401 from the xAI Responses API, the agent
refreshes the token, swaps it back into `self.api_key`, and retries
the call once. Guarded against silent account swaps when the active
key was sourced from a different (manual) pool entry.
* Auxiliary tasks (curator, vision, embeddings, etc.) route through a
dedicated xAI Responses-mode auxiliary client instead of falling back
to OpenRouter billing.
* Direct HTTP tools (`tools/xai_http.py`, transcription, TTS, image-gen
plugin) resolve credentials through a unified runtime → singleton →
env-var fallback chain so xai-oauth users get them for free.
* `hermes auth add xai-oauth` and `hermes auth remove xai-oauth N` are
wired through the standard auth-commands surface; remove cleans up
the singleton loopback_pkce entry so it doesn't silently reinstate.
* `hermes model` provider picker shows
"xAI Grok OAuth (SuperGrok Subscription)" and the model-flow falls
back to pool credentials when the singleton is missing.
Hardening
---------
* Discovery and refresh responses validate the returned
`token_endpoint` host against the same `*.x.ai` allowlist as the
authorization endpoint, blocking MITM persistence of a hostile
endpoint.
* Discovery / refresh / token-exchange `response.json()` calls are
wrapped to raise typed `AuthError` on malformed bodies (captive
portals, proxy error pages) instead of leaking JSONDecodeError
tracebacks.
* `prompt_cache_key` is routed through `extra_body` on the codex
transport (sending it as a top-level kwarg trips xAI's SDK with a
TypeError).
* Credential-pool sync-back preserves `active_provider` so refreshing
an OAuth entry doesn't silently flip the active provider out from
under the running agent.
Testing
-------
* New `tests/hermes_cli/test_auth_xai_oauth_provider.py` (~63 tests)
covers JWT expiry, OAuth URL params (plan + referrer), CORS origins,
redirect URI validation, singleton↔pool sync, concurrency races,
refresh error paths, runtime resolution, and malformed-JSON guards.
* Extended `test_credential_pool.py`, `test_codex_transport.py`, and
`test_run_agent_codex_responses.py` cover the pool sync-back,
`extra_body` routing, and 401 reactive refresh paths.
* 165 tests passing on this branch via `scripts/run_tests.sh`.
Wrap requests.post() in create_session() for browser_use, browserbase,
and firecrawl providers with requests.RequestException handling.
Connection timeouts and DNS resolution failures now surface as clean
RuntimeError messages instead of raw requests exception tracebacks.
Browser Use managed-gateway mode preserves raw exception propagation
so the existing idempotency-key retry semantics keep working.

Three asyncio.gather() calls in tools/web_tools.py ran without
return_exceptions=True. A single failing task (e.g. LLM rate limit on
one URL) would raise out of gather() and discard every other
successfully fetched/summarized result.
Pass return_exceptions=True and filter BaseException entries with a
warning log before unpacking. Affects:
- chunk summarization gather (large web_extract pages)
- firecrawl per-result LLM post-processing
- tavily crawl per-result LLM post-processing
Closes#2744
Remove redundant inner `import re` and regex recompilation on every call in
_interpolate_env_vars. Add module-level _ENV_VAR_PATTERN compiled once.
Replace the separate _interpolate_value() in mcp_config.py (which used \w+
and would silently fail on env vars containing hyphens or dots) with the
shared _ENV_VAR_PATTERN from mcp_tool.py. Remove now-unused import re.
Cron mutation operations (run/pause/resume/remove) and 'hermes cron edit'
now accept a job name in addition to the hex ID, with case-insensitive
matching. Before this, 'hermes cron run my_job_name' died with
'Job with ID my_job_name not found' and forced the user to look up the
hex ID first.
The original PR matched by name but silently picked the first match when
two jobs shared a name. This version refuses to act on an ambiguous name
and surfaces every matching job (id, name, schedule, next_run_at) so the
caller can pick a specific ID.
- cron/jobs.py:
- get_job() stays ID-only (preserves existing call-site semantics for
web_server/api_server/curator/scheduler/test code that always passes
real IDs).
- resolve_job_ref() is the new name-or-ID resolver, used by pause/
resume/trigger/remove_job. Exact ID match wins over a name match
even if a different job's name happens to equal that ID. Ambiguous
name match raises AmbiguousJobReference with all candidate IDs.
- tools/cronjob_tools.py: dispatch site uses resolve_job_ref, surfaces
ambiguous matches as a structured error with the matching IDs.
- hermes_cli/cron.py: 'cron edit' uses resolve_job_ref so editing by
name works and ambiguous names are reported with IDs.
- tests/cron/test_jobs.py: new TestResolveJobRef covering ID match,
case-insensitive name match, ID-wins-over-name, ambiguous refusal,
and that pause/resume/trigger/remove all refuse on ambiguity.
Closes#2627
When the in-tree FAL path has no API key (and no managed gateway), the
handler used to return a bare 'FAL_KEY environment variable not set'
error. Users had no idea where to get a key, that a managed Nous
gateway exists, or that plugin-registered providers are an option.
Now `image_generate_tool` returns a structured multi-line message:
- signup link (https://fal.ai)
- managed-gateway status (if Nous tools are enabled)
- pointer to `hermes tools` / `hermes plugins list` for alternate
backends, so users on a stale `image_gen.provider` know where to look
The schema is untouched — `check_fn` still gates the tool out of the
schema when no backend is reachable at startup, consistent with every
other conditional tool. This patch fixes the call-time failure modes:
managed-gateway 5xx, plugin provider disappearing mid-session, etc.
Inspired by #2546 / @Mibayy. The PR was ~5700 commits stale against
the new plugin-aware image_gen architecture, so this is a forward port
of the actionable-error idea rather than a cherry-pick.
Closes#2543

Discord's CDN serves attachments with Content-Encoding: br. aiohttp's
compression_utils tries 'import brotlicffi as brotli' first and falls back
to google's Brotli, but Brotli<1.2.0's Decompressor.process() is 1-arg
while aiohttp calls it with 2 args (data, max_length). Result: every
.txt/.md/.doc uploaded to a Discord-gateway session fails to decode at
att.read() with 'Can not decode content-encoding: br' / 'TypeError:
process() takes exactly 1 argument (2 given)', the agent never sees the
bytes, and falls back to filesystem guessing.
Pin brotlicffi==1.2.0.1 in both surfaces:
- tools/lazy_deps.py 'platform.discord' tuple: Discord users on the
lazy-install path get it on first discord.py import.
- pyproject.toml [messaging] extra: users who explicitly install
hermes-agent[messaging] (skipping the lazy path) get it eagerly.
brotlicffi wins aiohttp's import race regardless of what else is
installed (try brotlicffi / except: import brotli), so existing setups
that already pulled google's Brotli transitively don't change behavior
beyond the bug fix. ~1.5 MB wheel, manylinux/macOS/Windows coverage.
E2E verified: round-trip decode of Brotli-compressed payload via
aiohttp.compression_utils.brotli succeeds with brotlicffi pinned; same
test against Brotli==1.1.0 alone reproduces the reported TypeError.
Credit to @Korkyzer for the original diagnosis and fix shape in #15744;
the lazy-deps gating layer was added on top to keep brotlicffi out of
the install path for users who don't run a Discord gateway.
Fixes#12511.
Closes#15744.

Follow-up to the sandbox-bypass env-var fix:
- Update the opt-out gate so a user-provided AGENT_BROWSER_ARGS is also
respected, not just the legacy AGENT_BROWSER_CHROME_FLAGS. Previously
the gate only checked the broken legacy var, so a user who pre-set
AGENT_BROWSER_ARGS would still get clobbered by Hermes's auto-injection.
- Document AGENT_BROWSER_ARGS in .env.example, the browser feature page,
and the env var reference, with notes about the auto-injection on
AppArmor-restricted systems (Ubuntu 23.10+, DGX Spark, containers).
- Add Anadi Jaggia to AUTHOR_MAP.
AGENT_BROWSER_CHROME_FLAGS is not read by agent-browser CLI.
The correct env var is AGENT_BROWSER_ARGS, with comma-separated values.
This fixes Chrome 'No usable sandbox' crash on Ubuntu 23.10+ systems
where AppArmor restricts unprivileged user namespaces. The detection
logic was correct but the fix used the wrong environment variable name
and space-separated instead of comma-separated args.
Pre-existing diagnostics below an edit point used to surface as 'LSP
diagnostics introduced by this edit' whenever the edit deleted or
inserted lines. The delta-filter key included the diagnostic's
range, so the same logical error reported at a different line in
the post-edit snapshot looked like a brand new diagnostic.
Concrete case: deleting 14 lines in cli.py caused Pyright errors at
lines 9873, 10590, 12413, 13004 (unrelated to the edit) to be
reported as introduced by it.
Fix: build a piecewise-linear line-shift map (via difflib's
SequenceMatcher) from pre and post content, and remap baseline
diagnostics into post-edit coordinates before the set-difference.
Diagnostics in deleted regions drop out cleanly; diagnostics below
the edit shift by the right amount; diagnostics above are untouched.
The strict (range-aware) equality key stays — so a genuinely new
instance of an identical error class at a different line still
surfaces as new.
Pieces:
- agent/lsp/range_shift.py — build_line_shift, shift_diagnostic_range,
shift_baseline. Pure functions, no LSP state.
- agent/lsp/manager.py — LSPService.get_diagnostics_sync gains an
optional line_shift kwarg; baseline is shift_baseline'd before
computing the seen-set. _diag_key keeps the strict range key.
- tools/file_operations.py — write_file captures pre_content for any
LSP-handled extension (not just LINTERS_INPROC) and passes pre/post
to _maybe_lsp_diagnostics, which builds the shift map.
- New _lsp_handles_extension helper guards the pre_content read.
Trade-offs preserved:
- Genuinely new same-class errors at different lines still surface
(content-only key would have swallowed them).
- Pre-existing errors at unshifted positions still get filtered
(covered by the strict-key path with no shift).
- Best-effort: when pre_content can't be captured (file didn't
exist, permissions), the unshifted comparison still catches
most pre-existing errors; the edge case it misses is a new file
with a non-empty baseline, which is structurally impossible.
Pyproject's [all] extra was slimmed down in May 2026 — ~20 optional
backends moved to tools/lazy_deps.py and only install on first use.
hermes update runs uv pip install -e .[all] which doesn't touch any of
them, so pin bumps in LAZY_DEPS (CVE response, transitive fixes) were
silently ignored on already-activated backends.
Two changes:
1. _is_satisfied() now parses the spec and checks the installed version
against the constraint via packaging.specifiers. Previously it
returned True the moment the package name was importable, which made
ensure() a name-presence gate rather than a version-pin gate.
2. New active_features() / refresh_active_features() pair: lists every
feature with at least one of its packages currently installed, then
re-runs ensure() on each. Refresh is invoked at the end of
_cmd_update_impl, right after the [all] install completes. Cold
backends (never activated) stay quiet — no churn for them.
Output during update is one summary block:
→ Refreshing 4 active lazy backend(s)...
↑ 1 refreshed: provider.anthropic
✓ 3 already current
or
⚠ memory.honcho failed to refresh: <pip stderr>
Failures never raise out of update — backends keep their previously-
installed version and we tell the user to rerun once upstream is fixed.
security.allow_lazy_installs=false is honored: features get marked
"skipped" with the reason shown.
Tests: 18 new unit tests covering version-aware satisfaction (exact pin,
range, extras blocks, missing package, malformed spec), active feature
discovery, and refresh status reporting. All 61 lazy_deps tests pass.
The _foreground_background_guidance() function matched background-wrapper
keywords (nohup/disown/setsid) anywhere in the command text, including
inside quoted strings, Python -c code, commit messages, and PR body text.
Two-layer fix:
1. Strip single-quoted, double-quoted, and backtick-quoted content before
pattern matching via _strip_quotes() helper.
2. Tighten the regex to only match keywords at command-start positions
(after ^, ;, &, &&, ||, or $() — not mid-argument.
Both layers are needed: quote stripping handles the common case of keywords
in string literals, and the position-aware regex handles unquoted cases
like 'export FOO=setsid' (word boundary match, wrong position).
Fixes#20064
Cross-provider delegation (e.g. MiniMax parent → DeepSeek child) must not
inherit the parent's api_mode, because each provider uses a different API
surface: MiniMax uses 'anthropic_messages' while DeepSeek uses
'chat_completions'. Inheriting the wrong mode causes 404 errors.
When the effective provider differs from the parent's provider, derive
api_mode from the target provider's defaults instead (None triggers
re-derivation).
Refs: Bug #20558, PR #20563
Surfaced by local E2E behavior-parity testing of PR vs origin/main: the
plugin-migrated dispatchers were quietly changing the error envelope
shape returned to function-calling models on unconfigured systems.
Two findings, both from per-result error wrapping bleeding into the
pre-flight configuration error path:
1. **search**: ``firecrawl.search()`` caught the
``ValueError("Web tools are not configured...")`` from
``_get_firecrawl_client()`` and returned it as
``{"success": False, "error": ...}``, losing the legacy
``{"error": "Error searching web: ..."}`` envelope that
``tool_error()`` emits on main. Models that special-case the
``error`` key still detect the failure, but the prefix is part of
the legacy contract some users rely on.
2. **crawl**: ``firecrawl.crawl()`` caught the same pre-flight
``ValueError`` and wrapped it as a per-page error inside
``results[0]``. Main short-circuits on ``check_firecrawl_api_key()``
BEFORE dispatching, so its unconfigured response is
``{"success": False, "error": "web_crawl requires Firecrawl..."}``
at the top level. The PR's per-page burying hid the failure inside
``results[]`` where models that check ``result.get("error")`` would
miss it.
Fix:
- ``plugins/web/firecrawl/provider.py``: pull
``_get_firecrawl_client()`` outside the broad ``try`` in
``search()``. Pre-flight ``ValueError`` / ``ImportError`` propagate
to the dispatcher's top-level exception handler. In-flight SDK
errors still get wrapped as ``{"success": False, ...}``.
- ``tools/web_tools.py``: mirror main's upstream availability gate in
``web_crawl_tool``. When the resolved crawl provider is
``is_available()==False``, short-circuit BEFORE dispatching with the
same top-level error shape main emits.
- ``tests/tools/test_web_providers.py``: 2 regression tests
(``TestUnconfiguredErrorEnvelopeParity``) lock in the behavior so
future plugin work can't undo this.
Verified via local subprocess-based parity test (14/14 scenarios match
origin/main shape exactly) and full 210/210 web test suite green.
The web-provider migration originally left firecrawl crawl as the only
provider-specific code remaining inline in tools/web_tools.py (~250
lines of Firecrawl-specific crawl orchestration that didn't fit the
plugin's existing surface). This commit closes that gap.
What this adds
--------------
1. plugins/web/firecrawl/provider.py: implement async ``crawl(url, **kwargs)``
- Accepts the same kwargs as the dispatcher passes to any crawl
provider (``instructions``, ``depth``, ``limit``); Firecrawl's
/crawl endpoint ignores ``instructions`` and ``depth`` so we log
and drop with a clear info message.
- Wraps the sync SDK ``crawl()`` call in asyncio.to_thread so the
gateway event loop isn't blocked on a multi-page crawl.
- Preserves the response-shape normalization across pydantic /
typed-object / dict variants that the legacy inline code did.
- Preserves per-page website-policy re-check (catches blocked
redirects after the SDK returns).
- Returns the same {"results": [...]} shape so the dispatcher's
shared LLM-summarization post-processing path works unchanged.
- Sets supports_crawl() to True so the dispatcher routes through
the plugin instead of the legacy fallthrough.
2. tools/web_tools.py: delete the entire legacy firecrawl crawl block
that used to run after "No registered provider supports crawl" —
~270 lines including:
- check_firecrawl_api_key gate + typed error
- inline SSRF + website-policy seed-URL gate (dispatcher already
does this)
- Firecrawl client setup with crawl_params
- 100+ lines of pydantic/dict/typed-object normalization
- Per-page LLM-processing loop (kept in the dispatcher's shared
post-processing path; that's where it always belonged)
- trimming + base64 image cleanup (still done in the dispatcher's
shared path)
Replaced with a single typed-error branch when no crawl-capable
provider is available: "web_crawl has no available backend. Set
FIRECRAWL_API_KEY (or FIRECRAWL_API_URL for self-hosted), or set
TAVILY_API_KEY for Tavily."
Test updates
------------
- tests/tools/test_website_policy.py:
- test_web_crawl_short_circuits_blocked_url: dispatcher seed-URL
gate still runs on web_tools.check_website_access (no change to
that patch), but the firecrawl client lockdown moved to the
plugin module — patch firecrawl_provider._get_firecrawl_client
instead of web_tools._get_firecrawl_client. The dispatcher
short-circuits before the plugin runs, so the test still passes.
- test_web_crawl_blocks_redirected_final_url: patch the per-page
policy gate at plugins.web.firecrawl.provider.check_website_access
(where it now runs) AND on web_tools (where the seed-URL gate
still runs). Patch firecrawl_provider._get_firecrawl_client for
the FakeCrawlClient injection. Both checks flow through the same
fake_check function.
- tests/plugins/web/test_web_search_provider_plugins.py:
- Update parametrized capability-flag spec: firecrawl supports_crawl
is now True.
- Add test_firecrawl_crawl_returns_error_dict_when_unconfigured —
verifies inspect.iscoroutinefunction(p.crawl) is True and that
the async crawl returns a per-page error dict (not a raise) when
FIRECRAWL_API_KEY is missing.
Verified
--------
- 218/218 web tests pass (was 173, +44 plugin tests + 1 new firecrawl
crawl test from this commit = 218 with the test deduplication).
- Compile-clean (py_compile passes on both files).
- Provider capabilities matrix confirmed end-to-end:
name search extract crawl async-extract? async-crawl?
firecrawl True True True True True
tavily True True True False False
Both crawl-capable providers exercise the dispatcher's
inspect.iscoroutinefunction async-or-sync detection.

Removes the legacy in-tree provider scaffolding that PR #25182 fully
replaced with the plugin architecture:
tools/web_providers/__init__.py (6 lines)
tools/web_providers/base.py (89 lines — old ABCs)
tools/web_providers/ARCHITECTURE.md (73 lines — old design doc)
These were the staging-ground ABCs and provider modules that the
plugin migration absorbed. All seven web providers now implement the
single :class:`agent.web_search_provider.WebSearchProvider` ABC and
live under ``plugins/web/<vendor>/``. Nothing else in the tree imports
``tools.web_providers`` — verified via grep before deletion.
Test migration (tests/tools/test_web_providers.py)
--------------------------------------------------
Rewrote ``TestWebProviderABCs`` to test the new unified ABC at
:mod:`agent.web_search_provider`:
- test_cannot_instantiate_abc_directly — abstract ``name`` + ``is_available``
- test_concrete_search_only_provider_works — exercise default
``supports_extract=False`` / ``supports_crawl=False`` flags
- test_concrete_multi_capability_provider_works — exercise all three
capabilities, async extract supported (declared sync here for
simplicity; real plugins like parallel + firecrawl use async)
- test_search_only_provider_skips_extract_and_crawl — verify
``supports_*()`` flags default to False so search-only providers
don't have to implement extract() or crawl()
The 9 other tests in the file (per-capability backend selection,
DEFAULT_CONFIG merge, dispatcher routing) test public helpers in
``tools.web_tools`` that still exist and pass unchanged.
agent/web_search_provider.py docstring updated to reflect that the
legacy ABCs no longer exist; the response-shape contract is preserved
bit-for-bit so external consumers see no behavioral change.
Net diff
--------
- tools/web_providers/ removed (-168 lines)
- tests/tools/test_web_providers.py rewritten ABC section (+78/-30 net,
same coverage, new API)
- agent/web_search_provider.py docstring (-3/+5 lines)
Verified
--------
- 173/173 targeted web tests pass
- 12/12 ABC contract tests pass with the new interface
- No remaining grep hits for ``tools.web_providers`` outside of
intentional historical references in plugin docstrings.
Removes ~580 lines of dead code from tools/web_tools.py that were
superseded by the plugin migration but kept around in the cutover commit
to keep the diff focused. Replaces them with thin re-export shims so
existing tests and external callers that reach for the legacy
``tools.web_tools.<name>`` paths continue to work transparently.

- build_vendor_gateway_url, _read_nous_access_token,
resolve_managed_tool_gateway, managed_nous_tools_enabled,
prefers_gateway (tests patch tools.web_tools.<name>)
Plugin indirection pattern (key technique)
------------------------------------------
For functions inside the firecrawl/parallel/exa plugins to honor
unit-test patches that target ``tools.web_tools.<name>``, the plugin
implementations now do ``import tools.web_tools as _wt`` at call time
and read helper names through that module (``_wt._read_nous_access_token``,
``_wt.Firecrawl``, ``_wt.prefers_gateway``, etc.). This makes the
existing test patches transparently reach the plugin code without any
test changes.
The cached client globals (_firecrawl_client, _firecrawl_client_config,
_parallel_client, _async_parallel_client, _exa_client) also now live on
tools.web_tools so existing test setup_method handlers that reset
``tools.web_tools._<vendor>_client = None`` between cases keep working.
The plugins read/write the cache via getattr/setattr on the web_tools
module.
Verified

- Compile-clean (py_compile.compile passes)
- All inline implementations now exist in exactly one place
(plugins.web.<vendor>.provider)
Follow-up clean-up
------------------
- Drop _WEB_PLUGIN_SKIPLIST + hardcoded TOOL_CATEGORIES["web"] rows
(next commit)
- Delete tools/web_providers/ directory entirely
- Add tests/plugins/web/ coverage
- Full tests/tools/ + tests/gateway/ regression sweep before promoting PR
Two regressions discovered by running the full tests/tools/ suite after
the dispatcher cutover, both fixed in this commit:
1. web_crawl_tool incorrectly errored "search-only" for firecrawl
---------------------------------------------------------------------
The cutover treated any provider with supports_crawl()==False as a
search-only backend and returned the typed search-only error. But
firecrawl can crawl via the legacy multi-page-extract path inside
web_crawl_tool — it just doesn't expose supports_crawl on the plugin
(adding native firecrawl crawl is a clean follow-up).
Fix: only emit the search-only error when the provider supports
NEITHER crawl NOR extract (brave-free / ddgs / searxng). When the
provider supports extract but not crawl (firecrawl), fall through to
the legacy firecrawl-via-extract path below.
2. firecrawl plugin's check_website_access wasn't patchable
---------------------------------------------------------------------
The plugin imported `from tools.website_policy import check_website_access`
INSIDE the extract() function body, so monkeypatching the name on
plugins.web.firecrawl.provider had no effect — the inner import re-bound
the name on every call.
Fix: hoist the import to module level. Cheap (website_policy itself
has no heavy deps) and makes the standard
monkeypatch.setattr(firecrawl_provider, "check_website_access", ...)
pattern work.
Test updates (tests/tools/test_website_policy.py — 4 tests):
- test_web_extract_short_circuits_blocked_url
- test_web_extract_blocks_redirected_final_url
Both: patch the gate at plugins.web.firecrawl.provider (where it
runs after migration) and force the firecrawl plugin to be the
active extract provider via FIRECRAWL_API_KEY.
- test_web_crawl_short_circuits_blocked_url
- test_web_crawl_blocks_redirected_final_url
Both: unchanged — the dispatcher-level gate at tools.web_tools.py
line 1651 still uses the imported `check_website_access` name and
the firecrawl-fallthrough path is exercised as before.
Verified: 22/22 tests/tools/test_website_policy.py pass.
Cuts over web_search_tool, web_extract_tool, and web_crawl_tool in
tools/web_tools.py to dispatch through agent.web_search_registry
instead of the legacy hardcoded if-elif backend chains.
Per-tool changes:
web_search_tool (sync)
Replace 5 backend branches (parallel, exa, registry-3-providers,
tavily, firecrawl-fallthrough) with a single registry path:
1. _get_search_backend() resolves the configured name
2. _wsp_get_provider(name) for explicit-config-wins semantics
3. get_active_search_provider() fallback for typo / unknown name
4. provider.search(query, limit) — sync for all 7 providers
web_extract_tool (async)
Replace 4 backend branches (parallel-async, exa-sync, tavily-sync,
search-only-error, firecrawl-perurl-loop) with:
1. Same provider resolution as search.
2. When configured backend IS registered but doesn't support
extract (search-only providers like brave-free), surface a
typed "search-only" error matching the legacy text — tests
assert that wording.
3. inspect.iscoroutinefunction(provider.extract) detects sync vs
async: parallel + firecrawl are async; exa + tavily are sync.
Sync extracts run in asyncio.to_thread() so we don't block.
web_crawl_tool (async)
Replace tavily-specific branch + search-only-error block with:
1. _wsp_get_provider(backend) — explicit config first
2. Search-only typed error when the configured name doesn't
support crawl (matches legacy phrasing)
3. get_active_crawl_provider() fallback otherwise
4. provider.crawl(url, **kwargs) — async-or-sync dispatch as above
5. Response post-processing (LLM summarization, trimming) stays
unchanged — it's not provider-specific.
When no plugin advertises supports_crawl, falls through to the
existing Firecrawl-via-web-summarize path below (unchanged).
Test updates (2 tests in tests/tools/test_web_tools_config.py):
- test_web_search_clamps_limit_before_backend_call:
patch("tools.web_tools._parallel_search") -> patch the registry
provider returned by agent.web_search_registry.get_provider
- test_search_error_response_does_not_expose_diagnostics:
patch("tools.web_tools._get_firecrawl_client") -> same pattern
Tests unchanged (still pass):
- All TestXBackendWiring classes (test _get_backend / _is_backend_available
config-resolution, independent of dispatch)
- All TestXSearchOnlyErrors classes (test the search-only error path
via web_extract_tool / web_crawl_tool — error text preserved)
- 141 passing web tests total, 0 regressions.
Dead-code cleanup deferred to a follow-up commit so this diff stays
focused on the cutover. After this commit:
- tools.web_tools._exa_search / _exa_extract / _parallel_search /
_parallel_extract / _tavily_request / _normalize_tavily_* /
_get_firecrawl_client / _extract_web_search_results /
_extract_scrape_payload / _to_plain_object / _normalize_result_list
are no longer called by the dispatchers, but still exist.
- The config-resolution layer (_get_backend, _is_backend_available,
_is_tool_gateway_ready, _has_direct_firecrawl_config) IS still in
use and must stay.
- The Firecrawl proxy and check_firecrawl_api_key are still imported
by integration tests and patched by unit tests — must stay (or be
re-exported from the plugin).
Deletes tools/web_providers/{brave_free,ddgs,searxng}.py — the three
providers that moved to plugins/web/ in prior commits. tools/web_tools.py
no longer imports them (registry dispatch as of d8735963f), so removing
them is purely a cleanup pass.
Also migrates the existing tests to the new import paths:
tests/tools/test_web_providers_brave_free.py
tests/tools/test_web_providers_ddgs.py
tests/tools/test_web_providers_searxng.py
Mechanical rewrites:
- `from tools.web_providers.X import YSearchProvider`
-> `from plugins.web.X.provider import YWebSearchProvider`
- `.is_configured()` -> `.is_available()` (legacy method -> new method)
- `.provider_name()` -> `.name` (legacy method -> new property)
- `from tools.web_providers.base import WebSearchProvider`
-> `from agent.web_search_provider import WebSearchProvider`
(the subclass-check asserts membership in the new plugin-facing ABC)
- `sys.modules.delitem("tools.web_providers.ddgs")` updated to point at
`plugins.web.ddgs.provider` (cache-busting for lazy ddgs imports)
The TestXBackendWiring / TestXSearchOnlyErrors classes (covering
_is_backend_available, _get_backend, check_web_api_key, and the
"search-only" error paths in web_extract/web_crawl) are untouched —
those still test web_tools.py's backend-selection logic, which continues
to recognize the names "brave-free" / "ddgs" / "searxng" even after the
modules behind them moved to plugins.
tools/web_providers/base.py is intentionally NOT deleted by this commit
— it's the parent ABC of the legacy modules and shares its name with
agent/web_search_provider.py::WebSearchProvider. Removing it surfaces the
naming collision (see PR description Finding 0); the real migration PR
deletes it in the same commit that drops the _WEB_PLUGIN_SKIPLIST
guards in hermes_cli/tools_config.py.
Test results:
bash scripts/run_tests.sh tests/tools/test_web_providers_*.py
-> 65 passed in 3.41s (all rewritten unit tests + unchanged integration tests)
bash scripts/run_tests.sh tests/tools/test_web_*.py
-> 141 passed in 4.70s (full web test set, post-deletion)
The three migrated providers (brave-free, ddgs, searxng) are now dispatched
through agent.web_search_registry.get_provider() instead of importing
their concrete classes directly. The four inline providers (parallel, exa,
tavily, firecrawl) keep their existing branches — they live in
tools/web_tools.py itself and aren't part of this spike's plugin extraction.
The legacy tools/web_providers/{brave_free,ddgs,searxng}.py modules are
still in place (untouched by this commit) — Task 10 deletes them once the
real migration PR is ready. Keeping them alive during the spike means
revertibility is trivial.
E2E verified:
1. Plugin discovery registers ['brave-free','ddgs','searxng']
2. Config web.search_backend: brave-free resolves to the plugin instance
3. Dispatch result matches the original {success, data.web[]} contract
4. compile OK; no new LSP errors beyond pre-existing ones in web_tools.py
Fixes#25028.
The lazy-install hooks added in #25014 installed packages correctly but
failed to rebind module-level globals after install:
- Slack: missing aiohttp rebind → NameError on file uploads
- Feishu: none of the ~25 lark_oapi symbols rebound → TypeError on
adapter instantiation
- Matrix: mautrix.types enums stayed as stubs → mismatched values at
runtime
Introduces tools.lazy_deps.ensure_and_bind() — a DRY helper that
combines ensure() + importer-callable + globals().update(). This
eliminates the error-prone pattern of manually listing every global
that needs updating after lazy-install. Each platform adapter now
defines a single _import() function returning all bindings.
Also fixes: pyproject.toml [slack] extra was missing aiohttp (needed
by slack-bolt's async path).
Follow-up on @pty819's t2a_v2 endpoint fix:
- Default model: speech-02 -> speech-02-hd (bare 'speech-02' is not in the
supported enum; t2a_v2 rejects it with 400). Official enum: speech-01-hd,
speech-01-turbo, speech-02-hd, speech-02-turbo, speech-2.6-hd/turbo,
speech-2.8-hd/turbo.
- Default voice: female-shaonv -> English_expressive_narrator. The
legacy speech-01-series short ID doesn't resolve cleanly on the
speech-02+ models that are now the default.
- Default base URL: api.minimaxi.com -> api.minimax.io (matches the
canonical host in the published docs; api-uw.minimax.io is the
reduced-latency alt).
- Add GroupId support via tts.minimax.group_id config or MINIMAX_GROUP_ID
env var. Some MiniMax accounts scope TTS requests by group; without it,
requests 401. Only appended when not already in the user's base_url.
Tests rewritten to cover both the default t2a_v2 path (hex-encoded audio
in JSON, nested voice_setting/audio_setting) and the legacy
text_to_speech path (raw audio bytes, flat payload). Adds coverage for
GroupId config/env wiring and error surfacing.
Also adds AUTHOR_MAP entry for pty819's GitHub-noreply email.
The MiniMax TTS defaults were outdated:
- DEFAULT_MINIMAX_MODEL was 'speech-01' but MiniMax now uses 'speech-02'
- DEFAULT_MINIMAX_BASE_URL was 'https://api.minimax.chat/v1/text_to_speech'
which no longer works; the correct endpoint is
'https://api.minimaxi.com/v1/t2a_v2'
Users who configured tts.provider: minimax were getting model-not-supported
errors because the hardcoded defaults did not match available API permissions.
* feat(video_gen): unified video_generate tool with pluggable provider backends
One core video_generate tool, every backend a plugin. Mirrors the
image_gen + memory_provider + context_engine architecture: ABC, registry,
plugin-context registration hook, and per-plugin model catalogs surfaced
through hermes tools.
Surface (one schema, every backend):
- operation: generate / edit / extend
- modalities: text-to-video (prompt only), image-to-video (prompt +
image_url), video edit (prompt + video_url), video extend (video_url)
- reference_image_urls, duration, aspect_ratio, resolution,
negative_prompt, audio, seed, model override
- Providers ignore unknown kwargs and declare what they support via
VideoGenProvider.capabilities() — backend-specific quirks stay in the
backend, the agent learns one tool
Backends shipped:
- plugins/video_gen/xai/ — Grok-Imagine, full generate/edit/extend +
image-to-video + reference images (salvaged from PR #10600 by
@Jaaneek, reshaped into the plugin interface)
- plugins/video_gen/fal/ — Veo 3.1 (t2v + i2v), Kling O3 i2v,
Pixverse v6 i2v with model-aware payload building that drops keys a
model doesn't declare
Wiring:
- agent/video_gen_provider.py — VideoGenProvider ABC, normalize_operation,
success_response / error_response, save_b64_video / save_bytes_video,
$HERMES_HOME/cache/videos/
- agent/video_gen_registry.py — thread-safe register/get/list +
get_active_provider() reading video_gen.provider from config.yaml
- hermes_cli/plugins.py — PluginContext.register_video_gen_provider()
- hermes_cli/tools_config.py — Video Generation category in
hermes tools, plugin-only providers list, model picker per plugin,
config write to video_gen.{provider,model}
- toolsets.py — new video_gen toolset
- tests: 31 new tests covering ABC, registry, tool dispatch, both plugins
- docs: developer-guide/video-gen-provider-plugin.md (parallel to the
image-gen guide), sidebar + toolsets-reference + plugin guides updated
Supersedes: #25035 (FAL), #17972 (FAL), #14543 (xAI), #13847 (HappyHorse),
#10458 (provider categories), #10786 (xAI media+search bundle), #2984
(FAL duplicate), #19086 (Google Veo standalone — easy port to plugin
interface).

* feat(video_gen): dynamic schema reflects active backend's capabilities
Address the 'capability variance' question — instead of one tool with a
static schema that lies about what every backend supports, the
video_generate tool now rebuilds its description at get_definitions()
time based on the configured video_gen.provider and video_gen.model.
The agent sees backend-specific guidance up-front:
- 'fal-ai/veo3.1/image-to-video': 'image-to-video only — image_url is
REQUIRED; text-only prompts will be rejected'
- 'fal-ai/veo3.1' (t2v): no image_url restriction shown
- xAI grok-imagine-video: 'operations: generate, edit, extend; up to 7
reference_image_urls'
- Backends without edit/extend: 'not supported on this backend — surface
that they need to switch backends via hermes tools'
This is the same pattern PR #22694 used for delegate_task self-capping —
documented in the dynamic-tool-schemas skill. Cache invalidation is
free: get_tool_definitions() already memoizes on config.yaml mtime, so a
mid-session backend swap rebuilds the schema automatically.
Tested:
- Empirical FAL OpenAPI schema check confirms image-to-video models
require image_url (FAL returns HTTP 422 otherwise) — client-side
rejection in FALVideoGenProvider.generate() now prevents the wasted
round-trip
- Live E2E: fal-ai/veo3.1/image-to-video + prompt-only → clean
missing_image_url error; fal-ai/veo3.1 + prompt-only → dispatches
- 6 new tests cover the builder (no config / image-only / full-surface /
text-only / unknown provider / registry wiring), all passing
- 37/37 in the slice, 134/134 in the broader regression set
* test(video_gen/xai): full surface integration tests + cleaner schema
Verified end-to-end that the xAI plugin handles every documented mode
from PR #10600's surface: text-to-video, image-to-video,
reference-images-to-video, video edit, video extend (with and without
prompt). All five modes route to the correct xAI endpoint
(/videos/generations, /videos/edits, /videos/extensions) with the right
payload shape (image / reference_images / video keys), and all five
client-side rejections fire before the network: edit-without-prompt,
extend-without-video_url, image+refs conflict, >7 references, and
duration/aspect_ratio clamping.
15 new integration tests grouped into four classes (endpoint routing,
modalities, validation, clamping). httpx is stubbed via a small fake
AsyncClient that records POSTs so the tests assert the actual payload
the plugin would send to xAI — not just the success/error envelope.
Also cleaned up a description redundancy: when a model's operations
match the backend's overall set, we no longer print the duplicate
'operations supported by this model' line. xAI's description now reads:
Active backend: xAI . model: grok-imagine-video
- operations supported by this backend: edit, extend, generate
- modalities supported by this backend: image, reference_images, text
- aspect_ratio choices: 16:9, 1:1, 2:3, 3:2, 3:4, 4:3, 9:16
- resolution choices: 480p, 720p
- duration range: 1-15s
- reference_image_urls: up to 7 images

* feat(video_gen): collapse surface to t2v + i2v, family-based auto-routing
Two design changes per Teknium:
1) Drop edit/extend from the tool surface entirely. Only text-to-video
and image-to-video remain. The agent sees a clean tool with two
modalities; backend-specific quirks like xAI's edit/extend endpoints
stay out of the unified schema.
2) FAL: pick a model FAMILY once, the plugin routes between the
family's text-to-video and image-to-video endpoints based on whether
image_url was passed. Users no longer pick 'fal-ai/veo3.1' AND
'fal-ai/veo3.1/image-to-video' as separate options — they pick
'veo3.1', and the plugin handles the rest.
Catalog rewritten as families:
veo3.1 fal-ai/veo3.1 / fal-ai/veo3.1/image-to-video
pixverse-v6 fal-ai/pixverse/v6/text-to-video / fal-ai/pixverse/v6/image-to-video
kling-o3-standard fal-ai/kling-video/o3/standard/text-to-video / fal-ai/kling-video/o3/standard/image-to-video
xAI uses a single endpoint (/videos/generations) for both modes,
routed by the presence of the 'image' field in the payload — no
edit/extend exposure.
Schema changes:
- VIDEO_GENERATE_SCHEMA: drop operation, drop video_url. Final params:
prompt (required), image_url, reference_image_urls, duration,
aspect_ratio, resolution, negative_prompt, audio, seed, model.
- VideoGenProvider ABC: drop normalize_operation, VALID_OPERATIONS,
DEFAULT_OPERATION. capabilities() drops 'operations' key.
- success_response: add 'modality' field ('text' | 'image') so the
agent and logs can see which endpoint was actually hit.
Dynamic schema builder simplified — no operations bullet, no
'switch backends if you need edit/extend' guidance. When the active
backend supports both modalities (the common case), description reads:
Active backend: FAL . model: pixverse-v6
- supports both text-to-video (omit image_url) and image-to-video
(pass image_url) - routes automatically
- aspect_ratio choices: 16:9, 9:16, 1:1
- resolution choices: 360p, 540p, 720p, 1080p
- duration range: 1-15s
- audio: pass audio=true to enable native audio (pricing tier)
- negative_prompt: supported
Tests: 51 in the video_gen slice, 216 across the broader image+video
sweep, all passing. New FAL routing tests prove pixverse-v6 + no image
hits text-to-video endpoint, pixverse-v6 + image_url hits
image-to-video endpoint, same for veo3.1 and kling-o3-standard.
Docs updated: developer-guide page rewrites the 'model families' pattern
as a first-class section so external plugin authors know the convention.
toolsets-reference and toolsets.py descriptions match the new surface.

* feat(video_gen/fal): expand catalog to 6 families, cheap + premium tiers
Catalog now covers everything Teknium specced from FAL:
Cheap tier:
ltx-2.3 fal-ai/ltx-2.3-22b/text-to-video / image-to-video
pixverse-v6 fal-ai/pixverse/v6/text-to-video / image-to-video
Premium tier:
veo3.1 fal-ai/veo3.1 / fal-ai/veo3.1/image-to-video
seedance-2.0 bytedance/seedance-2.0/text-to-video / image-to-video
kling-v3-4k fal-ai/kling-video/v3/4k/text-to-video / image-to-video
happy-horse fal-ai/happy-horse/text-to-video / image-to-video
DEFAULT_MODEL moved from veo3.1 (premium) to pixverse-v6 (cheap, sane
defaults, both modalities) — better first-run UX for users who haven't
explicitly picked a model.
New family-entry knob: image_param_key. Kling v3 4K's image-to-video
endpoint expects start_image_url instead of image_url; declaring
image_param_key='start_image_url' on the family lets _build_payload
remap correctly. Other families default to plain image_url.
Per-family capability flags reflect each model's docs:
- LTX 2.3 + Happy Horse: minimal payloads (no duration/aspect/resolution
enum exposed by FAL — let endpoint apply defaults)
- Seedance: 6 aspect ratios incl 21:9, durations 4-15, audio supported,
negative prompts NOT supported per docs
- Kling v3 4K: 16:9/9:16/1:1, 3-15s, audio + negative
- Veo 3.1: unchanged, 16:9/9:16, 4/6/8s
Tests: +5 covering the new families (full catalog, Kling 4K
start_image_url remap, Seedance routing, LTX payload minimality, Happy
Horse minimality). 56/56 in the slice green.
Note: I did NOT add the FAL-hosted xAI Grok-Imagine variant. Hermes
already has a direct xAI plugin that talks to xAI's own API; routing
the same model through FAL's wrapper would duplicate the surface
without adding capabilities. Users on FAL who want Grok-Imagine should
use the xAI plugin directly; flag if you want both routes available.
* test(video_gen): tool-surface routing matrix — every model x modality
End-to-end matrix test driven through _handle_video_generate() — the
actual function the agent's video_generate tool call lands in. Writes
config.yaml, invokes the registered handler with a raw args dict, then
asserts the outbound HTTP/SDK call hit the right endpoint with the right
payload shape.
Parametrized over FAL_FAMILIES.keys() so the matrix auto-discovers new
families as they're added (add a family to FAL_FAMILIES and you get
both modalities tested for free).
Coverage:
- All 6 FAL families x {text-only, text+image} = 12 cases
- xAI x {text-only, text+image} = 2 cases
- tool-level model= arg overrides config = 2 cases
For each case, verifies:
- result['success'] is True
- result['modality'] matches input shape ('text' if no image_url, 'image' otherwise)
- outbound endpoint URL matches the family's text_endpoint or image_endpoint
- text-only payloads carry no image-shaped keys
- text+image payloads carry the family's image key (image_url for most,
start_image_url for kling-v3-4k, wrapped 'image' object for xAI)
All 16 cases passing. Confirms the tool surface routes every
(provider, model, modality) combination correctly with zero leakage.
* feat(video_gen): keep video_gen out of first-run setup, surface in status
Two changes:
1. video_gen joins _DEFAULT_OFF_TOOLSETS, so it is NOT pre-selected in
the first-run toolset checklist. Video gen is niche, paid, and slow —
most users don't want it nagging them during initial setup. Anyone
who wants it opts in via 'hermes tools' -> Video Generation, which
already routes to the provider+model picker.
2. The 'hermes setup' status panel learns about video_gen — but only
shows the row when a plugin reports available. Users without
FAL_KEY/XAI_API_KEY see nothing about video gen; users with one of
those keys see 'Video Generation (FAL) ✓' as confirmation it's wired.
Verified live:
- Fresh install (no creds): zero video_gen mentions in wizard.
- With FAL_KEY: status row appears with active backend name.
- 160/160 in the setup + tools_config + video_gen test slice.
Rationale: image_gen is on by default because it's a featured creative
tool used in casual chat (telegrams, etc). Video gen is heavier — long
wait, paid per-second pricing. Default-off matches user intent better.

skill_view ran the direct-path strategy across every skill dir before
the recursive strategy, so a top-level skill in an external dir could
silently shadow a same-named nested local skill. /skills correctly
listed the local version (deduped local-first by _find_all_skills) but
skill_view loaded the external one — confusing, and a real bug class
for users with skills.external_dirs registered alongside categorized
local skills.
Pick a louder fix than @polkn's PR #6136 proposed: collect every match
across all dirs (direct path, recursive by parent dir name, legacy
flat <name>.md), and if there's more than one, refuse with an error
that surfaces every matching path plus a hint to load by the
categorized form. Local-first precedence would have replaced silent
external-shadowing with silent same-name collisions between two
externals, or made an externally-shadowed-by-local skill unreachable
by bare name with no signal. Refusing forces the user to disambiguate
once and never wonder which skill ran.
Recovery: pass the full categorized path
("foundations/runtime/explore-codebase" instead of
"explore-codebase"), or rename one of the colliding skills.

Addresses CONTRIBUTING.md Priority #3 (Security hardening — shell injection).
Only Discord and Telegram had lazy-install hooks in their
check_*_requirements() functions. The remaining four platforms that were
moved to lazy_deps (Slack, Matrix, DingTalk, Feishu) would just return
False immediately if their packages weren't pre-installed — no attempt
to install them at runtime.
This means even with the .venv permissions fix (#24841), these four
platforms would still fail to load in Docker (or any fresh install)
unless the user manually ran pip install.
Add the same lazy_deps.ensure() pattern to all four, matching the
existing Discord/Telegram implementation.
* feat(nous): unified client=hermes-client-v<version> tag on every Portal request
Every Hermes request to Nous Portal now carries the same
client=hermes-client-v<__version__> tag (e.g. client=hermes-client-v0.13.0
on this release), sourced live from hermes_cli.__version__. The release
script's regex bump auto-aligns it on every release.
Centralized in agent/portal_tags.py and wired into all four call sites:
- NousProfile.build_extra_body (main agent loop, every chat completion)
- auxiliary_client.NOUS_EXTRA_BODY + _build_call_kwargs (aux client)
- run_agent.py compression-summary fallback path
- tools/web_tools.py web_extract fallback
Replaces the client=aux marker added in #24194 with the unified version
tag. Tests assert against the helper output (invariant) rather than the
literal string, so they don't need updating on every release.
* feat(nous): cover /goal judge and kanban specify aux paths
Two aux-using surfaces bypassed call_llm by invoking
client.chat.completions.create() directly without extra_body, so they
were missing the unified Portal client tag:
- hermes_cli/goals.py — /goal standing-goal judge
- hermes_cli/kanban_specify.py — kanban triage specifier
Both now pass extra_body=get_auxiliary_extra_body() or None so they
inherit the version tag when the aux client points at Nous Portal, and
emit nothing otherwise (no tag leak to OpenRouter/Anthropic auxes).
The live adapter path in _send_via_adapter called adapter.send() without
passing thread_id, while the standalone fallback path correctly forwarded
it. For plugin platforms (google_chat, teams, irc, line) running with the
gateway in-process, this caused every threaded reply to land as a new
top-level message instead of continuing the thread.
Matches the pattern already used by _send_matrix_via_adapter and
_send_feishu: build metadata={"thread_id": thread_id} and pass it through.
In WSL2, sounddevice.query_devices() returns [] even when the
PulseAudio bridge is functional. The existing code already handled
the case where the query itself raises an exception, but it missed
the empty-list case.
This change treats an empty device list as non-fatal in WSL when
PULSE_SERVER is configured, matching the existing exception-handler
behavior.
Fixes: WSL users seeing 'No audio input/output devices detected'
even though paplay/arecord work fine.
Tavily's /crawl endpoint requires Authorization: Bearer <key> in the header,
unlike /search and /extract which accept api_key in the JSON body.
Without the header, crawl returns 401 Unauthorized.
_parse_target_ref() has no handler for XMPP JIDs (user@server or
room@conference.server), so they fall through to the final
`return None, None, False`. This causes send_message to fail when
targeting an XMPP chat by JID, since the JID is not numeric and
doesn't match any other platform pattern.
Add an explicit check for XMPP targets containing '@', matching the
existing Matrix pattern above it.
Three follow-ups to PR #24168 found during live E2E testing on TS/bash files:
1. typescript-language-server now installs the typescript SDK (tsserver)
alongside it. Without that sibling install, initialize() failed with
"Could not find a valid TypeScript installation" and the server was
marked broken — no diagnostics ever reached the agent. New extra_pkgs
field on INSTALL_RECIPES makes that explicit and reusable for future
peer-dep cases.
2. _check_lint now treats "linter command exists on PATH but cannot
actually run" as skipped instead of error. The motivating case is
npx tsc when typescript is not in node_modules — npx prints its
"This is not the tsc command you are looking for" banner and exits
non-zero, which previously blocked the LSP semantic tier (gated on
success or skipped). Pattern-matched per base command (npx,
rustfmt, go) so genuine lint errors still flow through normally.
3. hermes lsp status now surfaces a Backend warnings section when
bash-language-server is installed but shellcheck is missing. The
server itself spawns fine but bash-language-server delegates
diagnostics to shellcheck — without it on PATH the integration
looks alive but never reports any problems. Same warning is
logged once at server spawn time.
Validation:
- 12 new tests in tests/agent/lsp/test_install_and_lint_fixes.py:
* recipe carries typescript SDK
* _install_npm passes both pkg + extras to npm CLI
* backwards compat: recipes without extras still work
* _backend_warnings quiet when bash absent / both present
* _backend_warnings fires when bash installed without shellcheck
* status output includes the Backend warnings section
* _looks_like_linter_unusable catches the npx tsc banner
* real TS type errors not misclassified as unusable
* unfamiliar linters fall through normally
* _check_lint returns skipped on npx tsc unusable
* _check_lint returns error on real tsc type errors
- Full lsp + file_operations test suite: 245/245 pass
- Live E2E:
* try_install("typescript-language-server") installs both packages
into node_modules
* write_file(bad.ts, ...) returns lint=skipped + lsp_diagnostics
with two real TS errors (was lint=error, no lsp_diagnostics)
* hermes lsp status renders the shellcheck warning when bash is
installed but shellcheck is not on PATH
The clarify tool returned 'not available in this execution context' for
every gateway-mode agent because gateway/run.py never passed
clarify_callback into the AIAgent constructor. Schema actively encouraged
calling it; users never saw the question.
Changes:
- tools/clarify_gateway.py — new event-based primitive mirroring
tools/approval.py: register/wait_for_response/resolve_gateway_clarify
with per-session FIFO, threading.Event blocking with 1s heartbeat
slices (so the inactivity watchdog keeps ticking), and
clear_session for boundary cleanup.
- gateway/platforms/base.py — abstract send_clarify with a numbered-text
fallback so every adapter (Discord, Slack, WhatsApp, Signal, Matrix,
etc.) gets a working clarify out of the box. Plus an active-session
bypass: when the agent is blocked on a text-awaiting clarify, the next
non-command message routes inline to the runner's intercept instead
of being queued + triggering an interrupt. Same shape as the /approve
deadlock fix from PR #4926.
- gateway/platforms/telegram.py — concrete send_clarify renders one
inline button per choice plus '✏️ Other (type answer)'. cl: callback
handler resolves numeric choices immediately, flips to text-capture
mode for Other, with the same authorization guards as exec/slash
approvals.
- gateway/run.py — clarify_callback wired at the cached-agent per-turn
callback assignment site (only the user-facing agent path; cron and
hygiene-compress agents have no human attached). Bridges sync→async
via run_coroutine_threadsafe, blocks with the configured timeout, and
returns a '[user did not respond within Xm]' sentinel on timeout so
the agent adapts rather than pinning the running-agent guard. Text-
intercept added to _handle_message before slash-confirm intercept
(skipping slash commands). clear_session called in the run's finally
to cancel any orphan entries.
- hermes_cli/config.py — agent.clarify_timeout default 600s.
- website/docs/user-guide/messaging/telegram.md — Interactive Prompts
section.
Tests:
- tests/tools/test_clarify_gateway.py (14 tests) — full primitive
coverage: button resolve, open-ended auto-await, Other flip, timeout
None, unknown-id idempotency, clear_session cancellation, FIFO
ordering, register/unregister notify, config default.
- tests/gateway/test_telegram_clarify_buttons.py (12 tests) — render
paths (multi-choice/open-ended/long-label/HTML-escape/not-connected),
callback dispatch (numeric resolve/Other flip/already-resolved/
unauthorized/invalid-token), and base-adapter text fallback.
Out of scope: bot-to-bot, guest mode, checklists, poll media, live
photos. Closes#24191.
* feat(lsp): semantic diagnostics from real language servers in write_file/patch
Wire ~26 language servers (pyright, gopls, rust-analyzer, typescript-language-server,
clangd, bash-language-server, ...) into the post-write lint check used by write_file
and patch. The model now sees type errors, undefined names, missing imports, and
project-wide semantic issues introduced by its edits, not just syntax errors.
LSP is gated on git workspace detection: when the agent's cwd or the file being
edited is inside a git worktree, LSP runs against that workspace; otherwise the
existing in-process syntax checks are the only tier. This keeps users on
user-home cwds (Telegram/Discord gateway chats) from spawning daemons.
The post-write check is layered: in-process syntax check first (microseconds),
then LSP semantic diagnostics second when syntax is clean. Diagnostics are
delta-filtered against a baseline captured at write start, so the agent only
sees errors its edit introduced. A flaky/missing language server can never
break a write -- every LSP failure path falls back silently to the syntax-only
result.
New module agent/lsp/ split into:
- protocol.py: Content-Length JSON-RPC framer + envelope helpers
- client.py: async LSPClient (spawn, initialize, didOpen/didChange,
ContentModified retry, push/pull diagnostic stores)
- workspace.py: git worktree walk-up + per-server NearestRoot resolver
- servers.py: registry of 26 language servers (extension match,
root resolver, spawn builder per language)
- install.py: auto-install dispatch (npm install --prefix, go install
with GOBIN, pip install --target) into HERMES_HOME/lsp/bin/
- manager.py: LSPService (per-(server_id, root) client registry, lazy
spawn, broken-set, in-flight dedupe, sync facade for tools layer)
- reporter.py: <diagnostics> block formatter (severity-1-only, 20-per-file)
- cli.py: hermes lsp {status,list,install,install-all,restart,which}
Wired into tools/file_operations.py:
- write_file/patch_replace now call _snapshot_lsp_baseline before write
- _check_lint_delta gains a third tier: LSP semantic diagnostics when
syntax is clean
- All LSP code paths swallow exceptions; write_file's contract unchanged
Config: 'lsp' section in DEFAULT_CONFIG with enabled (default true),
wait_mode, wait_timeout, install_strategy (default 'auto'), and per-server
overrides (disabled, command, env, initialization_options).
Tests: tests/agent/lsp/ -- 49 tests covering protocol framing (encode and
read_message round-trip, EOF/truncation/missing Content-Length), workspace
gate (git walk-up, exclude markers, fallback to file location), reporter
(severity filter, max-per-file cap, truncation), service-level delta filter,
and an in-process mock LSP server that exercises the full client lifecycle
including didChange version bumps, dedup, crash recovery, and idempotent
teardown.
Live E2E verified end-to-end through ShellFileOperations: pyright
auto-installed via npm into HERMES_HOME, baseline captured, type error
introduced, single delta diagnostic surfaced with correct line/column/code/
source, then patch fix removes the diagnostic from the output.
Docs: new website/docs/user-guide/features/lsp.md page covering supported
languages, configuration knobs, performance characteristics, and
troubleshooting; cli-commands.md updated with the 'hermes lsp' reference;
sidebar updated.
* feat(lsp): structured logging, backend gate, defensive walk caps
Cherry-picks the substantive ideas from #24155 (different scope, same
problem space) onto our PR.
agent/lsp/eventlog.py (new): dedicated structured logger
``hermes.lint.lsp`` with steady-state silence. Module-level dedup sets
keep a 1000-write session at exactly ONE INFO line ("active for
<root>") at the default INFO threshold; clean writes log at DEBUG so
they never reach agent.log under normal config. State transitions
(server starts, no project root for a file, server unavailable) fire
at INFO/WARNING once per (server_id, key); novel events (timeouts,
unexpected errors) fire WARNING per call. Grep recipe: ``rg 'lsp\\['``.
agent/lsp/manager.py: wire the eventlog into _get_or_spawn and
get_diagnostics_sync so users can answer "did LSP fire on this edit?"
with a single grep, plus surface "binary not on PATH" warnings once
instead of silently retrying every write.
tools/file_operations.py: backend-type gate. ``_lsp_local_only()``
returns False for non-local backends (Docker / Modal / SSH /
Daytona); ``_snapshot_lsp_baseline`` and ``_maybe_lsp_diagnostics``
now skip entirely on remote envs. The host-side language server
can't see files inside a sandbox, so this prevents pretending to
lint a file the host process can't open.
agent/lsp/protocol.py: 8 KiB cap on the header block in
``read_message``. A pathological server that streams headers
without ever emitting CRLF-CRLF would have looped forever consuming
bytes; now raises ``LSPProtocolError`` instead.
agent/lsp/workspace.py: 64-step cap on ``find_git_worktree`` and
``nearest_root`` upward walks, plus try/except containment around
``Path(...).resolve()`` and child ``.exists()`` calls. Defensive
against pathological inputs (symlink loops, encoding errors,
permission failures mid-walk) — the lint hook is hot-path code and
must never raise.
Tests:
- tests/agent/lsp/test_eventlog.py: 18 tests covering steady-state
silence (clean writes stay DEBUG), state-transition INFO-once
semantics (active for, no project root), action-required
WARNING-once (server unavailable), per-call WARNING (timeouts,
spawn failures), and the "1000 clean writes => 1 INFO" contract.
- tests/agent/lsp/test_backend_gate.py: 5 tests verifying
_lsp_local_only / snapshot_baseline / maybe_lsp_diagnostics skip
the LSP layer for non-local backends and route correctly for
LocalEnvironment.
- tests/agent/lsp/test_protocol.py: new test_read_message_rejects_runaway_header
exercising the 8 KiB cap.
Validation:
- 73/73 LSP tests pass (49 original + 18 eventlog + 5 backend-gate + 1 framer cap)
- 198/198 pass when run alongside existing file_operations tests
- Live E2E re-run with pyright still surfaces "ERROR [2:12] Type
... reportReturnType (Pyright)" through the full path, then patch
fix removes it on the next call.
* feat(lsp): atexit cleanup + separate lsp_diagnostics JSON field
Two improvements salvaged from #24414's plugin-form alternative,
keeping our core-integrated design:
1. atexit cleanup of spawned language servers
----------------------------------------------------------------
``agent/lsp/__init__.get_service`` now registers an ``atexit``
handler on first creation that tears down the LSPService on
Python exit. Without this, every ``hermes chat`` exit was
leaking pyright/gopls/etc. processes for a few seconds while
their stdout buffers drained -- they got reaped by the kernel
eventually but a watchful ``ps aux`` would catch them.
The handler runs once per process (gated by
``_atexit_registered``); idempotent ``shutdown_service``
ensures double-fire is a no-op. Errors during shutdown are
swallowed at debug level since by the time atexit fires the
user has already seen the agent's final response.
2. Separate ``lsp_diagnostics`` field on WriteResult / PatchResult
----------------------------------------------------------------
Previously the LSP layer folded its diagnostic block into the
``lint.output`` string, conflating the syntax-check tier with
the semantic tier. The agent (and any downstream parsers) now
read syntax errors and semantic errors as independent signals:
{
"bytes_written": 42,
"lint": {"status": "ok", "output": ""},
"lsp_diagnostics": "<diagnostics file=...>\nERROR [2:12] ..."
}
``_check_lint_delta`` returns to its original two-tier shape
(syntax check + delta filter); ``write_file`` and
``patch_replace`` independently fetch LSP diagnostics via
``_maybe_lsp_diagnostics`` and pass them into the new field.
``patch_replace`` propagates the inner write_file's
``lsp_diagnostics`` so the outer PatchResult carries the patch's
delta correctly.
Tests: 19 new
- tests/agent/lsp/test_lifecycle.py (8 tests): atexit registration
fires once and only once across N get_service calls; the
registered callable is our internal shutdown wrapper;
shutdown_service is idempotent and safe when never started;
exceptions during shutdown are swallowed; inactive service is
cached so we don't rebuild on every check.
- tests/agent/lsp/test_diagnostics_field.py (11 tests): WriteResult
/ PatchResult dataclass shape, to_dict include/omit semantics,
channel separation (lint and lsp_diagnostics carry independent
signals), write_file populates the field via
_maybe_lsp_diagnostics only when the syntax tier is clean,
patch_replace propagates the field forward from its internal
write_file.
Validation:
- 92/92 LSP tests pass (73 prior + 8 lifecycle + 11 diagnostics field)
- 217/217 pass with file_operations + LSP combined
- Live E2E reverified: clean writes -> both fields empty/none; type
error introduced -> lint clean (parses), lsp_diagnostics carries
the pyright reportReturnType block; patch fix -> both fields
clean again.
* fix(lsp): broken-set short-circuit so a wedged server isn't paid every write
Discovered while auditing failure paths: a language server binary that
hangs (sleep forever, no LSP traffic on stdin/stdout) caused EVERY
subsequent write to re-pay the 8s snapshot_baseline timeout. Five
writes = ~64s of dead time.
The bug: ``_get_or_spawn`` adds the (server_id, root) pair to
``_broken`` inside its inner exception handler, but when the OUTER
``_loop.run`` timeout fires, it cancels the inner task before that
handler runs. The pair never makes it to broken-set, so the next
write re-enters the spawn path and re-pays the timeout.
Fix:
- New ``_mark_broken_for_file`` helper at the service layer marks
the (server_id, workspace_root) pair broken from the OUTSIDE when
the outer timeout fires. Called from the except branches in
``snapshot_baseline``, ``get_diagnostics_sync`` (asyncio.TimeoutError
+ generic Exception). Also kills any orphan client process that
survived the cancelled future, fire-and-forget with a 1s ceiling.
- ``enabled_for`` now consults the broken-set BEFORE returning True.
Files in already-broken (server_id, root) pairs short-circuit to
False, so the file_operations layer skips the LSP path entirely
with no spawn cost. Until the service is restarted (``hermes lsp
restart``) or the process exits.
- A single eventlog WARNING is emitted on first mark-broken so the
user knows which server gave up. Subsequent edits in the same
project stay silent.
Tests: 7 new in tests/agent/lsp/test_broken_set.py — covers the
key shape (server_id, per_server_root), enabled_for short-circuit,
sibling-file skip in same project, project isolation (broken in
A doesn't affect B), graceful no-op for missing-server / no-workspace,
and an end-to-end test that snapshots after a failure and verifies
the next ``enabled_for`` returns False.
Validation:
- Live retest of the wedged-binary scenario: 5 sequential writes,
first 8.88s (the one snapshot timeout), subsequent four ~0.84s
(no LSP cost). Down from 5x12.85s = 64s before this fix.
- 99/99 LSP tests pass (92 prior + 7 broken-set)
- 224/224 pass with file_operations + LSP combined
- Happy path E2E reverified — clean write, type error introduced,
patch fix all behave correctly with the new broken-set logic.
Note: the FIRST write to a wedged binary still pays 8s (the
snapshot_baseline timeout). We could shorten that, but pyright/
tsserver normally take 2-3s and slow CI rust-analyzer can need
5+ seconds, so 8s is the conservative ceiling. Subsequent writes
are instant.
Daytona ships breaking SDK changes on June 10, 2026 — `list()` returns
an iterator and the `page=` offset parameter is removed. We pin
daytona==0.155.0 so we're past the May 24 hard-cutoff, but the
legacy-sandbox resume path in DaytonaEnvironment still passes `page=1`
and reads `.items` off the result.
Switch to `next(iter(results), None)` against a single-result
`list(labels=..., limit=1)` call. Update tests to use `iter([...])`
and drop the `page=1` kwarg from list() assertions.
Allow integrations to share a visible Camofox identity with Hermes and recover existing tabs without carrying local patches.

* feat(security): supply-chain advisory checker + lazy-install framework + tiered install fallback
Three coordinated mitigations for the Mini Shai-Hulud worm hitting
mistralai 2.4.6 on PyPI (2026-05-12) and for the next single-package
compromise that follows.
# What this PR makes true
1. Users with the poisoned mistralai 2.4.6 in their venv get a loud
detection banner with copy-pasteable remediation steps the moment
they run hermes (and on every gateway startup).
2. One quarantined / yanked PyPI package can no longer silently demote
a fresh install to 'core only' — the installer keeps every other
extra and tells the user which tier landed.
3. Future opt-in backends (Mistral, ElevenLabs, Honcho, etc.) can
lazy-install on first use under a strict allowlist, instead of
eagerly pulling everything at install time.
# Detection: hermes_cli/security_advisories.py
- ADVISORIES catalog (one entry currently: shai-hulud-2026-05 for
mistralai==2.4.6). Adding the next one is a single dataclass.
- detect_compromised() uses importlib.metadata.version() — no pip
dependency, works in uv venvs that lack pip.
- Banner cache (~/.hermes/cache/advisory_banner_seen) rate-limits
the startup banner to once per 24h per advisory.
- Acks persisted to security.acked_advisories in config.yaml; never
re-banner after ack.
- Wired into:
* hermes doctor — runs first, prints full remediation block
* hermes doctor --ack <id> — dismisses an advisory
* cli.py interactive run() and single-query branches — short
stderr banner pointing at hermes doctor
* gateway/run.py startup — operator-visible warning in gateway.log
# Lazy-install framework: tools/lazy_deps.py
- LAZY_DEPS allowlist maps namespaced feature keys (tts.elevenlabs,
memory.honcho, provider.bedrock, etc.) to pip specs.
- ensure(feature) installs missing deps in the active venv via the
uv → pip → ensurepip ladder (matches tools_config._pip_install).
- Strict spec safety regex rejects URLs, file paths, shell metas,
pip flag injection, control chars — only PyPI-by-name accepted.
- Gated on security.allow_lazy_installs (default true) plus the
HERMES_DISABLE_LAZY_INSTALLS env var for restricted/audited envs.
- Migrated three backends as proof of pattern:
* tools/tts_tool.py — _import_elevenlabs() calls ensure first
* plugins/memory/honcho/client.py — get_honcho_client lazy-installs
* tts.mistral / stt.mistral entries pre-registered for when PyPI
restores mistralai
# Installer fallback tiers
scripts/install.sh, scripts/install.ps1, setup-hermes.sh:
- Centralised _BROKEN_EXTRAS list (currently: mistral). Edit one
array when a transitive breaks; users keep every other extra.
- New 'all minus known-broken' tier between [all] and the existing
PyPI-only-extras tier. Only kicks in when [all] fails resolve.
- All three tiers explicit: every fallback announces which tier
landed and prints a re-run hint when not on Tier 1.
- install.ps1 and install.sh both regenerate their tier specs from
the same _BROKEN_EXTRAS array so updates stay in sync.
Side effect: install.ps1 Tier 2 spec previously hardcoded 'mistral'
in its extra list — bug fixed by the refactor (mistral is filtered
out).
# Config
hermes_cli/config.py — DEFAULT_CONFIG.security gains:
- acked_advisories: [] (advisory IDs the user has dismissed)
- allow_lazy_installs: True (security gate for ensure())
No config version bump needed — both keys nest under existing
security: block, and load_config's deep-merge picks up DEFAULT_CONFIG
defaults for users with older configs.
# Tests
tests/hermes_cli/test_security_advisories.py — 23 tests covering:
- detect_compromised matches/non-matches, wildcard frozenset
- ack persistence, idempotence, blank rejection, config-failure path
- banner cache rate limiting + 24h re-banner + ack-stops-banner
- short_banner_lines / full_remediation_text / render_doctor_section /
gateway_log_message
- shipped catalog well-formedness invariant
tests/tools/test_lazy_deps.py — 40 tests covering:
- spec safety: 11 safe parametrized + 18 unsafe parametrized
- allowlist: unknown-feature rejection, namespace.name shape,
every shipped spec passes the safety regex
- security gating: config flag, env var, default, fail-open
- ensure() happy/sad paths: already-satisfied, install success,
pip stderr surfaced on failure, install-succeeds-but-still-missing
- is_available, feature_install_command
Combined: 63 new tests, all passing under scripts/run_tests.sh.
# Validation
- scripts/run_tests.sh tests/hermes_cli/test_security_advisories.py
tests/tools/test_lazy_deps.py → 63/63 passing

tests/tools/test_transcription_dotenv_fallback.py → 165/165 passing
- scripts/run_tests.sh tests/hermes_cli/ tests/tools/ →
9191 passed, 8 pre-existing failures (verified on origin/main
before this change)
- bash -n on install.sh and setup-hermes.sh → OK
- py_compile on all modified .py files → OK
- End-to-end smoke test of detect_compromised + render_doctor_section

* build(deps): pin every direct dep to ==X.Y.Z (no ranges)
Companion to the supply-chain advisory work: replace every >=/</~= range
in pyproject.toml's [project.dependencies] and [project.optional-dependencies]
with an exact ==X.Y.Z pin sourced from uv.lock.
Why: ranges allow PyPI to ship a fresh version of any direct dep at any
time without a code review on our side. With ranges, the malicious
mistralai 2.4.6 release would have been pulled by every fresh
'pip install -e .[all]' for the hours between upload and PyPI's
quarantine — exactly the install window we got hit on. Exact pins close
that window: the only way a new package version reaches a user is via
an intentional update on our end.
What the user-facing change is: nothing, behavior-wise. Every package
resolves to the same version it was already resolving to via uv.lock —
the pins just remove the resolver's freedom to pick a different one.
Cost: any user installing Hermes alongside another package that requires
a newer pin gets a resolver conflict. Acceptable for our isolated-venv
install path; documented in the new comment block.
Build-system requires line (setuptools>=61.0) is intentionally left
as a range — pinning the build backend would block fresh pip from
bootstrapping the build on architectures where that exact wheel isn't
available.
mistral extra (mistralai==2.3.0) is pinned but stays out of [all]
(per PR #24205). 'uv lock' regeneration will fail until PyPI restores
mistralai; lockfile regeneration is gated behind that, NOT on every PR.
LAZY_DEPS in tools/lazy_deps.py also moved to exact pins so the lazy-
install pathway can never resolve a different version than the one
declared in pyproject.toml.
Validation:
- Cross-checked all 77 pinned direct deps in pyproject.toml against
uv.lock — every pin matches the resolved version exactly.
- Cross-checked all LAZY_DEPS specs against uv.lock — same.
- 'uv pip install -e .[all] --dry-run' resolves 205 packages cleanly.
- tests/tools/test_lazy_deps.py + tests/hermes_cli/test_security_advisories.py
→ 63/63 passing (every shipped spec passes the safety regex).
- Doctor + TTS + transcription targeted suite → 146/146 passing.
* build(deps): hash-verify transitives via uv.lock; remove unresolvable [mistral] extra
You asked: 'what about the dependencies the dependencies rely on?' —
correctly noting that exact-pinning direct deps in pyproject.toml does
NOT cover the transitive graph. `pip install` and `uv pip install` both
re-resolve transitives fresh from PyPI at install time, so a compromised
transitive (e.g. `httpcore` if it got worm-poisoned tomorrow) would
still hit our users even with every direct dep exact-pinned.
# What this commit fixes
1. **Both real installer scripts now prefer `uv sync --locked` as Tier 0.**
uv.lock records SHA256 hashes for every transitive — a compromised
package with a different hash gets REJECTED. Falls through to the
existing `uv pip install` cascade if the lockfile is missing or
stale, with a loud warning that the fallback path does NOT
hash-verify transitives. Previously only `setup-hermes.sh` (the dev
path) used the lockfile; `scripts/install.sh` and `scripts/install.ps1`
(the paths fresh users actually run) skipped it.
2. **Removed the `[mistral]` extra entirely.** The `mistralai` PyPI
project is fully quarantined right now — every version returns 404,
so any pin we wrote was unresolvable, which broke `uv lock --check`
in CI. Restoration is documented in pyproject.toml as a 5-step
checklist (verify, re-add extra, re-enable in 4 modules, regenerate
lock, optionally re-add to [all]).
3. **Regenerated uv.lock.** 262 packages, mistralai/eval-type-backport/
jsonpath-python pruned. `uv lock --check` now passes.
# Defense-in-depth view
| Layer | Where | Protects against |
|----------------------------|-------------------|-------------------------------------------|
| Exact pins in pyproject | direct deps | new mistralai 2.4.6-style direct compromise |
| uv.lock + `--locked` install | transitive graph | transitive worm injection |
| Tier-0 hash-verified path | install.sh / .ps1 | actually USE the lockfile in fresh installs |
| `uv lock --check` CI gate | every PR | drift between pyproject and lockfile |
| `hermes_cli/security_advisories.py` | runtime | cleanup for users who already got hit |
The exact pinning + hash verification together close the supply-chain
gap. Without the lockfile path, exact pins alone are theater.
# Validation
- `uv lock --check` → passes (262 packages resolved, no drift).
- `bash -n` on install.sh + setup-hermes.sh → OK.
- 209/209 tests passing across new + adjacent test files
(test_lazy_deps.py, test_security_advisories.py, test_doctor.py,
test_tts_mistral.py, test_transcription_tools.py).
- TOML parse OK.
* chore: remove community announcement drafts (PR body covers it)
* build(deps): lazy-install every opt-in backend (anthropic, search, terminal, platforms, dashboard)
Extends the lazy-install framework to cover everything that's not used by
every hermes session. Base install drops from ~60 packages to 45.
Moved out of core dependencies = []:
- anthropic (only when provider=anthropic native, not via aggregators)
- exa-py, firecrawl-py, parallel-web (search backends; only when picked)
- fal-client (image gen; only when picked)
- edge-tts (default TTS but still optional)
New extras in pyproject.toml: [anthropic] [exa] [firecrawl] [parallel-web]
[fal] [edge-tts]. All added to [all].
New LAZY_DEPS entries: provider.anthropic, search.{exa,firecrawl,parallel},
tts.edge, image.fal, memory.hindsight, platform.{telegram,discord,matrix},
terminal.{modal,daytona,vercel}, tool.dashboard.
Each import site now calls ensure() before importing the SDK. Where the
module had a top-level try/except (telegram, discord, fastapi), the
graceful-fallback pattern was extended to lazy-install on first
check_*_requirements() call and re-bind module globals.
Updated test_windows_native_support.py tzdata check from snapshot
(>=2023.3 literal) to invariant (any version + win32 marker).
Validation:
- Base install: 45 packages (was ~60); 6 newly-extracted packages absent
- uv lock --check: passes (262 packages, no drift)
- 209/209 lazy_deps + advisory + doctor + tts/transcription tests passing
- py_compile clean on all 12 modified modules
The `mistralai` PyPI package was quarantined on 2026-05-12 after a
malicious 2.4.6 release. Every fresh resolve (AUR makepkg, Docker build,
CI run, install.sh first-run) currently fails on
`mistralai>=2.3.0,<3` because PyPI returns zero candidates.
Existing users running `hermes update` mostly didn't notice — `hermes
update` falls back from `.[all]` to per-extra retries and silently
skips mistral with a warning that scrolls past. But fresh installs
hard-fail or lose every other extra.
Changes:
- pyproject.toml: drop `hermes-agent[mistral]` from `[all]` and

can opt back in once PyPI un-quarantines.
- hermes_cli/tools_config.py: hide Mistral Voxtral TTS from the
`hermes tools` provider picker until restored.
- hermes_cli/web_server.py: drop "mistral" from dashboard STT options.
- tools/transcription_tools.py: explicit `provider: mistral` returns
"none" with a clear status message; auto-detect skips mistral.
- tools/tts_tool.py: dispatcher returns a clear "temporarily disabled"
error before any SDK import attempt (avoids cached-stale-package
surprises).
- tests/tools/: update three test files to assert the new disabled
behavior. Each test docstring records why and points at the rollback
trigger (PyPI un-quarantines mistralai).
Restore plan: revert this commit once the package is available on PyPI
again. The behavior change is intentional and documented in code
comments + test docstrings to make the rollback trivial.
Validation:
- scripts/run_tests.sh tests/tools/ -k 'mistral or stt or tts' →
425/425 passing.

Set HERMES_SESSION_ID using the existing session_context.py ContextVar
system for concurrency safety (multiple gateway sessions in one process
won't cross-talk). Also writes os.environ as fallback for CLI mode.
Touchpoints:
- gateway/session_context.py: Add _SESSION_ID ContextVar + _VAR_MAP entry
- run_agent.py: Set both ContextVar and os.environ at init and on
context-compression rotation
- tools/environments/local.py: Bridge ContextVars into subprocess env

Adds the only #17873 category not covered by the in-flight PRs #17962
(briandevans, reverse shell + download-execute) and #7993 (SHL0MS,
credential reads + curl/wget exfiltration): sudo invocations that an
LLM-driven agent can drive without TTY interaction.
The agent has no TTY, so the sudo forms that succeed without human
involvement are those reading the password from stdin (`-S` / `--stdin`)
or via an askpass helper (`-A` / `--askpass`). The shell-launch (`-s`)
and list-privileges (`-a`) flags are also gated since they are
privilege-relevant invocations the agent can chain after acquiring the
password (e.g. read SUDO_PASSWORD from .env -> sudo -S -s -> root shell).
Plain `sudo cmd` (no flag) is TTY-bound and excluded.
Two patterns:
1. Direct flag: `\bsudo\b[^;|&\n]*?\s+(?:-s\b|--stdin\b|-a\b|--askpass\b)`
The lazy `[^;|&\n]*?` consumes flag-arguments without spanning
command separators, so `sudo -u root -S whoami` matches (a textbook
offensive form that a strict `(?:\s+-[^\s]+)*` "leading flags only"
pattern would have missed because `root` is a flag-value not a flag).
2. Combined short flags: `\bsudo\b[^;|&\n]*?\s+-[a-z]*[sa][a-z]*\b`
Catches packed forms like `sudo -nS id` where multiple flags share
a single `-X` token.
`_normalize_command_for_detection` lowercases input before pattern
matching (tools/approval.py:340), so case variants of S/s and A/a
collapse — both letter-pairs are gated since each is a privilege-
relevant invocation.
Tests: 21 new cases in TestDetectSudoStdin (12 positive covering all
flag-order permutations including herestring source and printf-piped
forms; 9 negative including TTY-bound `sudo whoami`, interactive
`sudo -i`, env-var reference `$SUDO_USER`, doc lookup `man sudo`,
package install, and the `pseudosudo` word-boundary edge case).
Empirical coverage: 11/11 attacks matched, 0/10 false positives.

Fixes#9590: Block explicit sudo -S (stdin password mode) commands
when the SUDO_PASSWORD environment variable is not configured.
The attack vector: the LLM constructs 'echo guessedpass | sudo -S cmd'
to brute-force sudo passwords, iterates based on sudo's error output
('Sorry, try again'). The existing _transform_sudo_command only
injects -S when SUDO_PASSWORD exists; without it, the LLM's explicit
sudo -S must be treated as a guessing attempt.
Changes:
- Add _check_sudo_stdin_guard() in approval.py: detects sudo -S when
SUDO_PASSWORD is absent, anchored to command-start positions
(^ ; && || | etc.) to avoid false positives on literal text
- Integrate into check_all_command_guards() above yolo/mode=off so
the block is unconditional (like the hardline floor)
- Add 6 tests covering: detection, allow-list, SUDO_PASSWORD bypass,
integration with check_all_command_guards, yolo non-bypass,
container backend bypass
The kanban dispatcher sets HERMES_KANBAN_TASK on every spawned worker
but launches it with the assignee profile's HERMES_HOME (e.g.
~/.hermes/profiles/<name>/), which has no gateway.pid file. The
existing _check_send_message therefore returned False from the
is_gateway_running() fallback, even though the parent gateway is
alive and reachable.
Net effect: workers could call kanban_* tools (gated on
HERMES_KANBAN_TASK in _check_kanban_mode) but not send_message. This
breaks the natural pattern of "worker does the job, calls
send_message to deliver rich content to the originating chat, then
calls kanban_complete with a one-line summary" because the kanban
notifier's payload_summary is hard-truncated to the first line
(~200 chars) at gateway/run.py:3963 — anything richer has to ship
via send_message.
Honoring HERMES_KANBAN_TASK in _check_send_message — symmetric with
_check_kanban_mode in kanban_tools.py:42 — closes the gap. No new
state, no new env var, no profile-config changes required.
Two independent opt-in QoL toggles, both off by default.
terminal.docker_extra_args:
- List of extra flags appended verbatim to docker run after security
defaults. Useful for adding capabilities (e.g. --cap-add SETUID) or
other docker run options not exposed by existing config keys.
- Non-string entries are logged and skipped.
- Also available via TERMINAL_DOCKER_EXTRA_ARGS='[...]' env var.
display.timestamps:
- Appends [HH:MM] to user input bullet and the assistant response box
header. Single hub in _format_submitted_user_message_preview()
covers both single-line and multi-line user previews; assistant
response label gets the timestamp at box-open time.
Closes#1569 (timestamps).

When kanban_complete rejects a created_cards list as hallucinated, the
task is intentionally left in-flight (the gate runs before the write
txn) so the worker can retry with a corrected list or pass
created_cards=[] to skip the check. The retry path already worked, but
the previous error wording read like a terminal failure and workers
were observed abandoning the run instead of trying again.
Spell out the recovery path explicitly in the tool_error response
("Your task is still in-flight ... Retry kanban_complete with ...") and
add regression coverage at both the kernel and tool layers so the
retry contract — and the wording the worker depends on to discover
it — is pinned.
Fixes#22923
Adds CDPSupervisor.evaluate_runtime() and wires it into _browser_eval as a
fast path when a supervisor is alive for the current task_id. Replaces the
~180ms agent-browser subprocess fork+exec+Node-startup hop with a ~1ms
Runtime.evaluate over the supervisor's already-connected WebSocket.
Falls through to the existing agent-browser CLI path when no supervisor is
running (e.g. backends without CDP, or before the first browser_navigate
attaches one), so behaviour is unchanged where it can't apply.
JS-side exceptions surface directly without falling through to the
subprocess (the subprocess would just re-raise the same error, slower);
supervisor-side failures (loop down, no session) fall through cleanly.
Benchmark — 30 iterations of `1 + 1` against headless Chrome:
supervisor WS mean= 0.96ms median= 0.91ms
agent-browser subprocess mean=179.35ms median=167.73ms
→ 187x speedup mean
Tests: 14 unit tests (mocked supervisor + response-shape coverage), 5
real-Chrome e2e tests in test_browser_supervisor.py (gated on Chrome
being installed). Browser test suite: 355 passed, 1 skipped.
Adapted from PR #20568 commit ce3518578 (Eric Litovsky / @kallidean).
Adds two-tier gating for the kanban tool surface so dispatcher-spawned
workers see only task-lifecycle tools (show/complete/block/heartbeat/
comment/create/link) while orchestrator profiles with `toolsets: [kanban]`
also see board-routing tools (kanban_list, kanban_unblock).
Workers shouldn't be enumerating or unblocking the board — they should
close their own task via the lifecycle tools. Hiding board-routing tools
from worker schemas keeps the worker focused and the toolset-isolation
contract honest.
Plus inherited from the same upstream commit:
- 50/200 row bound on kanban_list with `truncated` + `next_limit` metadata.
- Belt-and-suspenders runtime guard `_require_orchestrator_tool()` inside
the orchestrator handlers in case a stale registration ever routes a
worker to one of them.
- Tests for the new gate, the stricter bound, and the fact that even a
worker with `toolsets: [kanban]` in config still doesn't see board
routing.

When the active main model has native vision and the provider supports
multimodal tool results (Anthropic, OpenAI Chat, Codex Responses, Gemini
3, OpenRouter, Nous), vision_analyze loads the image bytes and returns
them to the model as a multimodal tool-result envelope. The model then
sees the pixels directly on its next turn instead of receiving a lossy
text description from an auxiliary LLM.
Falls back to the legacy aux-LLM text path for non-vision models and
unverified providers.
Mirrors the architecture used in OpenCode, Claude Code, Codex CLI, and
Cline. All four converge on the same pattern: tool results carry image
content blocks for vision-capable provider/model combinations.
Changes
- tools/vision_tools.py: _vision_analyze_native fast path + provider
capability table (_supports_media_in_tool_results). Schema description
updated to reflect new behaviour.
- agent/codex_responses_adapter.py: function_call_output.output now
accepts the array form for multimodal tool results (was string-only).
Preflight validates input_text/input_image parts.
- agent/auxiliary_client.py: _RUNTIME_MAIN_PROVIDER/_MODEL globals so
tools see the live CLI/gateway override, not the stale config.yaml
default. set_runtime_main()/clear_runtime_main() helpers.
- run_agent.py: AIAgent.run_conversation calls set_runtime_main at turn
start so vision_analyze's fast-path check sees the actual runtime.
- tests/conftest.py: clear runtime-main override between tests.
Tests
- tests/tools/test_vision_native_fast_path.py: provider capability
table, envelope shape, fast-path gating (vision-capable model uses
fast path; non-vision model falls through to aux).
- tests/run_agent/test_codex_multimodal_tool_result.py: list tool
content becomes function_call_output.output array; preflight
preserves arrays and drops unknown part types.
Live verified
- Opus 4.6 + Sonnet 4.6 on OpenRouter: model calls vision_analyze on a
typed filepath, gets pixels back, reads exact text from images that
no aux description could capture (font color irony, multi-line
fruit-count list, etc.).
PR replaces the closed prior efforts (#16506 shipped the inbound user-
attached path; this PR closes the gap for tool-discovered images).
Linux's MAX_ARG_STRLEN caps any single argv element at 128 KB
(32 * PAGE_SIZE). The previous heredoc-in-the-command-string approach
in _write_to_sandbox put the entire tool result inside the 'bash -c'
arg, so any result over ~128 KB raised OSError [Errno 7] 'Argument
list too long' before the heredoc ever ran. The caller logged a
warning, but quiet_mode (CLI default) sets tools.* to ERROR — so the
warning never reached agent.log either, and the agent saw a 1.5 KB
preview tagged 'Full output could not be saved to sandbox'. Hits
delegate_task with 3+ subagent outputs routinely now.
Switch to passing content via env.execute(stdin_data=...). cmd is
now just 'mkdir -p X && cat > Y' (under 1 KB), and the heavyweight
payload travels through stdin where there is no argv-element limit.
E2E reproduced the user's exact 144,778-char delegate_task envelope:
old code OSError'd, new code round-trips cleanly to disk with all
three task summaries intact.
Problem: terminal.docker_env set in config.yaml was silently ignored.
Docker containers never received the user-specified env vars.
Root cause: docker_env was missing from all three config→env bridging
maps (cli.py env_mappings, gateway/run.py _terminal_env_map,
hermes_cli/config.py _config_to_env_sync) and from the terminal_tool
_get_env_config() reader. _create_environment() consumed the key from
container_config correctly, but it was always {} because TERMINAL_DOCKER_ENV
was never set.
Also extend the list-serialisation branches in cli.py and gateway/run.py
to handle dict values via json.dumps (lists already used json.dumps;
plain str() on a dict produces undecodable output).
Fix:
- cli.py: add "docker_env": "TERMINAL_DOCKER_ENV" to env_mappings;
serialise dict values with json.dumps alongside existing list path
- gateway/run.py: same additions to _terminal_env_map and serialisation
- hermes_cli/config.py: add "terminal.docker_env": "TERMINAL_DOCKER_ENV"
to _config_to_env_sync so `hermes config set terminal.docker_env …`
persists to .env correctly
- tools/terminal_tool.py: add docker_env key to _get_env_config() reading
TERMINAL_DOCKER_ENV via _parse_env_var with default "{}"
Tests: add test_docker_env_is_bridged_everywhere to
tests/tools/test_terminal_config_env_sync.py — stash-verified: fails on
origin/main, passes with fix.
Fixes#20537
After Popen succeeds with os.setsid (detached process group), 5 things
happen with no try/except: Thread construction, reader.start(), lock
acquisition, prune+register, checkpoint write. If any raises, the
Popen object goes unregistered and the detached process group leaks
indefinitely.
Wrap the post-spawn setup in try/except. On failure:
- os.killpg(getpgid(pid), SIGKILL) takes down the entire process
group (not just the shell - important because of detached PG +
-lic shell wrapper that may have spawned children)
- proc.kill() fallback for ProcessLookupError/PermissionError/OSError
- proc.wait(timeout=5) reaps with a bound
- re-raise to preserve original traceback
Nested try/except around cleanup so a secondary failure can't mask the
original.
Closes#2749.
Problem
=======
`tools.checkpoint_manager._touch_project` reads the project metadata
file with `json.loads(meta_path.read_text(...))`, then immediately does:
meta["workdir"] = str(_normalize_path(working_dir))
The `except` block only catches `(OSError, ValueError)`. When the file
parses successfully but returns a non-dict value (a list `[]`, `null`,
or a scalar from a corrupted or hand-truncated write), `json.loads`
succeeds without error and `meta` is set to, e.g., `[]`. The subsequent
subscript assignment then raises `TypeError: list indices must be
integers or slices, not str`, which is NOT caught by the narrow except
clause.
This TypeError propagates up through `_take` to `ensure_checkpoint`,
where the broad `except Exception` safety net swallows it. The effect
is that `ensure_checkpoint` silently returns False for the entire
session — all checkpoints are skipped for the affected working directory
without any user-visible error.
Root cause
==========
Missing `isinstance(meta, dict)` guard after `json.loads`, identical in
pattern to bugs fixed in `cron/jobs.py` (#22569) and
`tools/process_registry.py` (#22544). The same guard is already
present one function below in `_list_projects` (line 506), but was
inadvertently omitted in `_touch_project`.
Fix
===
Add two lines after the try/except:
```python
if not isinstance(meta, dict):
meta = {}
```
This matches the existing guard in `_list_projects` and ensures a fresh
empty dict is used whenever the persisted value is not a mapping —
preserving the `created_at` semantics via `setdefault` on the next line.
Tests
=====
`TestTouchProjectMalformedMeta` covers four non-dict root values
(`[]`, `null`, `42`, `"oops"`). Each writes a corrupted metadata file,
calls `_touch_project`, and asserts: (a) no exception raised, (b) the
metadata file is rewritten as a valid dict containing `last_touch` and
`workdir`. All four fail on main with `TypeError`, pass with fix.
Full `tests/tools/test_checkpoint_manager.py` regression: 77 passed.
`tools/image_generation_tool.py` did `import fal_client` at module
top, which pulled the entire fal_client + httpx + rich stack on every
process that ran `discover_builtin_tools()` — every `hermes` cold
start, even ones that never touch image generation.
Make the import lazy: replace the eager import with a placeholder
(`fal_client: Any = None`) and add an idempotent `_load_fal_client()`
that rebinds the module global on first use. Call it from the two
runtime entry points (`_ManagedFalSyncClient.__init__` and
`_submit_fal_request`) and from the SDK-presence check in
`check_image_generation_requirements`.
The loader short-circuits if the global is already truthy, which
preserves the test pattern of monkeypatching `fal_client` to install
a mock — the `monkeypatch.setattr(image_tool, "fal_client", ...)`
calls in test_image_generation.py keep working unchanged.
Measured impact (15-run min times, 9950X3D):
tools.image_generation_tool alone: 77 → 20 ms (-74%)
36 → 20 MB (-44%)
import cli (full): 734 → 720 ms (-2%)
import model_tools: 372 → 366 ms (-2%)
The microbench is dramatic but the full-CLI win is small — fal_client
shares its httpx + rich dependencies with the rest of the agent, so
on a real cold start most of the 16 MB / 64 ms is already paid by
other imports. The win matters mostly for processes that touch this
tool without otherwise loading httpx (rare) and for architectural
consistency with the previous lazy-load PRs (#22681 google_chat,
#22831 teams).
Tests: 55/55 `tests/tools/test_image_generation.py` pass, including
the cases that monkeypatch the module global to install a mock
fal_client. End-to-end verification confirms `import model_tools`
no longer pulls `fal_client` into `sys.modules`.
Pick openrouter/pareto-code as your model and OpenRouter auto-routes each
request to the cheapest model meeting your coding-quality bar (ranked by
Artificial Analysis). The new openrouter.min_coding_score config key (0.0-1.0,
default 0.65) tunes the floor.
- hermes_cli/models.py: add openrouter/pareto-code to OPENROUTER_MODELS so
it shows up in the picker with a description
- hermes_cli/config.py: add openrouter.min_coding_score (default 0.65 — lands
on a mid-tier coder on the current Pareto frontier)
- plugins/model-providers/openrouter: emit extra_body.plugins =
[{id: pareto-router, min_coding_score: X}] when model is openrouter/pareto-code
AND the score is a valid float in [0.0, 1.0]
- agent/transports/chat_completions.py: same emission on the legacy flag
path (when no provider profile is loaded)
- run_agent.py: openrouter_min_coding_score kwarg + storage; plumbed into
both build_kwargs() invocations and the context-summary extra_body path
- cli.py: read openrouter.min_coding_score once at init, validate float in
[0,1], pass to AIAgent constructions (CLI + background-task paths)
- cron/scheduler.py, batch_runner.py, tools/delegate_tool.py,
tui_gateway/server.py: propagate the kwarg (mirrors providers_order
plumbing — subagents inherit, cron/batch read from config)
- tests: profile-level + transport-level coverage of the model gating,
unset/empty/out-of-range handling, and the legacy flag path
- docs: new 'OpenRouter Pareto Code Router' section in providers.md
Verified end-to-end against api.openrouter.ai: at score=0.65 we land on a
mid-tier coder, at omission we get the strongest. Score is silently dropped
on any model other than openrouter/pareto-code, so it's safe to leave set.
acp_command / acp_args descriptions previously primed the model to
populate them — "Per-task ACP command override (e.g. 'copilot')" —
even when no ACP CLI was installed. Models with weaker schema-following
discipline would set them and the spawn would fail.
Add explicit "Do NOT set unless the user has explicitly told you"
guidance at both the top-level acp_command and the per-task override.
Strengthen acp_args to mention it's empty unless acp_command is set.
Adds 2 tests pinning the descriptions.
Note: this is a cosmetic prompt-engineering fix — the params remain
exposed in the schema. The fully-correct fix is to gate them behind
a config flag or runtime ACP-CLI detection so the schema only emits
them when an ACP harness is available. Tracked as a follow-up; this
PR ships the low-cost stopgap.
Salvage of #22680 (delegate schema only). The original PR also
bundled unrelated fixes for #22548, #21944, #22150 — those
need separate PRs since #22548 and #21944 are already addressed
on main (#22780 + #22798 in flight) and #22150 deserves its own
review.
Closes#22013.
Problem: `_get_cloud_provider()` set `_cloud_provider_resolved = True`
before resolution. If credentials were briefly unavailable on the first
call (e.g. a managed Nous Portal token mid-refresh), the resolver pinned
the entire process to local mode forever, even after credentials
self-healed seconds later.
Root cause: bookkeeping was set up-front, so any code path that fell
through to `return _cached_cloud_provider` (config read failure, no
credentials yet, explicit-provider instantiation failure) committed the
transient `None` to the cache permanently.
Fix: invert the bookkeeping. `_cloud_provider_resolved = True` is now
set only when (a) the user explicitly chose `cloud_provider: local`, or
(b) a provider was successfully resolved. All transient `None` paths
return without poisoning the cache, so the next call retries. Explicit
provider instantiation failures now log at warning level with stack
trace so operators can diagnose them.
Tests: 5 new cases in tests/tools/test_browser_cloud_provider_cache.py
covering explicit local, successful resolution, no-credentials-yet,
config read failure, and explicit provider instantiation failure.
Stash-verify confirmed the 3 transient-None tests fail without the fix.
All 320 existing browser tests still green.
Closes#22324
Returning users who enabled '🖱️ Computer Use (macOS)' via 'hermes tools'
saw '✓ Saved configuration' but no install — cua-driver was never on
PATH and the toolset failed at first use. Two compounding causes:
1. _toolset_needs_configuration_prompt fell through to _toolset_has_keys,
which returned True for any provider with empty env_vars. cua-driver
has no env vars, so the gate skipped _configure_toolset entirely and
_run_post_setup('cua_driver') never ran.
2. No stable CLI entry-point existed for re-running the install when
the picker no-op'd it (e.g. when toggling the toolset off+on inside
one picker session, where 'added' is empty).
Changes:
- hermes_cli/tools_config.py: add _POST_SETUP_INSTALLED registry
mapping post_setup keys to installed-state predicates. The gate
now returns True when any visible provider has a registered
post_setup whose predicate fails. cua_driver is the only opt-in
for now; other post_setup hooks keep their existing behaviour.
- hermes_cli/main.py: add 'hermes computer-use install' and
'hermes computer-use status' as a stable docs target. install
reuses the same _run_post_setup('cua_driver') path that the
picker invokes; status reports whether cua-driver is on PATH.
- tools/computer_use/cua_backend.py: install hint now points users
at 'hermes computer-use install' first.
- website/docs/user-guide/features/computer-use.md: document the
new command as the primary install path.
- website/docs/reference/cli-commands.md: catalog 'hermes
computer-use' alongside 'hermes tools'.
- tests/hermes_cli/test_post_setup_gating.py: regression coverage
for the gate predicate (missing -> setup forced, installed ->
setup skipped, broken predicate -> non-blocking, unregistered
keys -> behaviour unchanged).
Fixes#22737. Reported by @f-trycua.
The github-pr-workflow skill wraps the URL in double-quotes
('curl -H ... "https://api.github.com/..."'), which the original
allowlist regex (\s+https://api...) did not match. Without this,
the bundled github-pr-workflow skill is still blocked at every
cron tick despite #22605's fix landing for the bare-URL form.
Make the leading quote optional and add a regression test pinning
both single- and double-quoted forms.
The delegate_task tool description hardcoded 'default 3' / 'default 2' for
max_concurrent_children / max_spawn_depth, which misled the model on any
install that raised these limits — the schema text said 'default 3' even
when the user had set max_concurrent_children=15 / max_spawn_depth=3, so
the model would self-cap at 3 and never use the headroom.
Make the description dynamic. ToolEntry gains an optional
dynamic_schema_overrides callable; registry.get_definitions() merges its
output on top of the static schema before returning it. delegate_tool
registers a builder that reads the current delegation.* config and emits:
- 'up to N items concurrently for this user' (N = max_concurrent_children)
- 'Nested delegation IS enabled / OFF for this user (max_spawn_depth=N)'
- 'orchestrator children can themselves delegate up to M more level(s)'
- 'orchestrator_enabled=false' when the kill switch is set
The model_tools cache key already includes config.yaml mtime+size, so
edits to delegation.* in config invalidate the cached tool definitions
without an explicit hook. CLI_CONFIG staleness within a process is a
pre-existing limitation of _load_config and out of scope here.
Static description / tasks.description / role.description in
DELEGATE_TASK_SCHEMA are placeholders so module import doesn't trigger
cli.CLI_CONFIG load before the test conftest can redirect HERMES_HOME.
Plugin platforms (IRC, Teams, Google Chat) currently fail with
`No live adapter for platform '<name>'` when a `deliver=<plugin>` cron
job runs in a separate process from the gateway, even though the
platforms are eligible cron targets via `cron_deliver_env_var` (added
in #21306). Built-in platforms (Telegram, Discord, Slack, etc.) use
direct REST helpers in `tools/send_message_tool.py` so cron can deliver
without holding the gateway in the same process; plugin platforms
historically depended on `_gateway_runner_ref()` which returns `None`
out of process.
This change adds an optional `standalone_sender_fn` field to
`PlatformEntry` so plugins can register an ephemeral send path that
opens its own connection, sends, and closes without needing the live
adapter. The dispatch site in `_send_via_adapter` falls through to the
hook when the gateway runner is unavailable, with a descriptive error
when neither path applies. The hook is optional, so existing plugins
are unaffected.
Reference migrations land in the same change for IRC, Teams, and
Google Chat, exercising the hook across stdlib (asyncio + IRC protocol),
Bot Framework OAuth client_credentials, and Google service-account
flows respectively.
Security hardening on the new code paths:
* IRC: control-character stripping on chat_id and message body to
block CRLF command injection; bounded nick-collision retries; JOIN
before PRIVMSG so channels with the default `+n` mode accept the
delivery.
* Teams: TEAMS_SERVICE_URL validated against an allowlist of known
Bot Framework hosts (`smba.trafficmanager.net`,
`smba.infra.gov.teams.microsoft.us`) to block SSRF; chat_id and
tenant_id constrained to the documented Bot Framework character set;
per-request timeouts so a slow STS endpoint cannot starve the
activity POST.
* Google Chat: chat_id and thread_id validated against strict
resource-name regexes; service-account refresh wrapped in
`asyncio.wait_for` so a hung token endpoint cannot stall the
scheduler.
Test coverage: 20 new tests covering happy path, missing-config errors,
network failure modes, and each defensive validation. Existing tests
unchanged. `bash scripts/run_tests.sh tests/tools/test_send_message_tool.py
tests/gateway/test_irc_adapter.py tests/gateway/test_teams.py
tests/gateway/test_google_chat.py` reports 341 passed, 0 regressions.
Documentation: new "Out-of-process cron delivery" section in
website/docs/developer-guide/adding-platform-adapters.md and an entry
in gateway/platforms/ADDING_A_PLATFORM.md naming the hook.
Follow-up to PR #21293 (cli.py), which fixed the same anti-pattern.
`asyncio.get_event_loop()` is documented as effectively "always returns
the running loop when called from a coroutine" and emits
DeprecationWarning/RuntimeWarning in some interpreter configurations.
The Python docs explicitly recommend get_running_loop() inside coroutines.
Replaces the remaining 9 call sites that are unconditionally inside
async def bodies:
- tools/browser_cdp_tool.py — _cdp_call() (4 sites): deadline + remaining
computations inside the async websockets.connect context manager.
- hermes_cli/web_server.py — get_status, _start_device_code_flow,
submit_oauth_code (3 sites): all FastAPI async endpoints offloading
blocking httpx / PKCE work to run_in_executor.
- environments/agent_loop.py — HermesAgentLoop (1 site): tool dispatch
inside the async rollout loop.
- environments/benchmarks/terminalbench_2/terminalbench2_env.py —
rollout_and_score_eval (1 site): test verification thread offload.
All 9 sites are unconditionally inside async def bodies, so a running
loop is guaranteed and no try/except RuntimeError fallback is needed
(unlike the cli.py case in #21293, which ran from a background thread).
Behavior is identical on supported Python versions; aligns the codebase
with the post-#21293 idiom and avoids future warnings as the deprecation
hardens.
Salvaged from PR #21930 by @Zhekinmaksim onto current main (the
original branch was 109 commits behind and carried unintended
stale-branch reverts of unrelated landed changes — _tail_lines
encoding=utf-8 and the Windows PTY bridge guard). Only the 9 swaps
from the PR's intended scope are applied here.
Comments are injected into the next worker's system prompt by
build_worker_context() as '**{author}** (timestamp): {body}'. The
previous code accepted args['author'] as a free-form override and
exposed it on KANBAN_COMMENT_SCHEMA, which let a worker:
1. Receive a prompt-injection in a malicious task body.
2. Call kanban_comment with author='hermes-system' (or any other
authoritative-looking name) on a sibling task.
3. The next worker assigned to that sibling task sees the forged
comment in its boot context as what reads like a system-authored
directive.
Always derive author from HERMES_PROFILE (the dispatcher already sets
this per worker at hermes_cli/kanban_db.py:3718), and remove the
'author' property from the tool schema so the LLM can't see the
override surface.
Cross-task commenting itself remains unrestricted (see #19713) —
comments are the deliberate handoff channel between tasks; only the
author-override surface is closed.

SQLite's WAL mode requires shared-memory (mmap) coordination and fcntl
byte-range locks that don't reliably work on network filesystems. Upstream
documents this explicitly:
https://www.sqlite.org/wal.html#sometimes_queries_return_sqlite_busy_in_wal_mode
On NFS / SMB / some FUSE mounts / WSL1, 'PRAGMA journal_mode=WAL' raises
'sqlite3.OperationalError: locking protocol' (SQLITE_PROTOCOL). Before
this change, every feature backed by state.db or kanban.db broke silently:
- /resume, /title, /history, /branch returned 'Session database not
available.' with no cause
- gateway logged the init failure at DEBUG (invisible in errors.log)
- kanban dispatcher crashed every 60s, driving the known migration race
(duplicate column name: consecutive_failures, #21708 / #21374)
Changes:
- hermes_state.apply_wal_with_fallback(): shared helper that tries WAL
and falls back to DELETE on SQLITE_PROTOCOL-style errors with one
WARNING explaining why
- hermes_state.get_last_init_error() + format_session_db_unavailable():
capture the init failure cause and surface it in user-facing strings
(with an NFS/SMB pointer for 'locking protocol')
- hermes_cli/kanban_db.connect(): use the shared helper
- gateway/run.py: bump SessionDB init failure log DEBUG -> WARNING
(matches cli.py's existing correct behavior)
- cli.py (4 sites) + gateway/run.py (5 sites): replace bare
'Session database not available.' with format_session_db_unavailable()
Tests: 12 new tests in tests/test_hermes_state_wal_fallback.py + 1 new
test in tests/hermes_cli/test_kanban_db.py. Existing suites (state,
kanban, gateway, cli) remain green for all tests unrelated to pre-existing
failures on main.
Evidence: real-world user on NFSv3 mount (172.26.224.200:d2dfac12/home,
local_lock=none) reporting 'Session database not available.' on /resume;
'locking protocol' appears in 4 distinct log entries across backup,
kanban, TUI, and CLI paths in the same session.
closes#22032
Telegram forum supergroups address the General topic as
`message_thread_id="1"` on incoming updates, but the Bot API rejects
sends with `message_thread_id=1` ("Message thread not found"). The
gateway adapter has a `_message_thread_id_for_send` helper that maps
"1" to None for that reason; the standalone `_send_telegram` helper
used by the `send_message` tool never got the same mapping, so any
`send_message` call to a Topics-enabled group's General topic
(target shape `telegram:<chat_id>:1`) failed with "Message thread
not found."
Reuse the adapter's helper when available, with an explicit fallback
to the same mapping for environments where the adapter import path
fails (e.g. python-telegram-bot missing in this venv).
Fixes#22267
Models that enforce required-only constraints (e.g. kimi-k2.x) were
omitting old_string/new_string for replace mode and patch for patch mode
because the schema only declared required: ["mode"].
Add explicit "REQUIRED when mode='X'" markers to each conditionally-required
property description and a top-level "REQUIRED PARAMETERS: ..." summary for
each mode. Avoids anyOf/oneOf which break Anthropic, Fireworks, and
Kimi/Moonshot providers. Add TestPatchSchemaShape to lock the shape.

Interactive `hermes` launch drops from ~21s to ~2.5s. Three independent
fixes, each targets a distinct hot spot in the banner / tool-registration
path that fires on every CLI invocation.
1. `get_external_skills_dirs()` in-process mtime cache (~10s saved)
The function re-read + YAML-parsed the full ~/.hermes/config.yaml on
every call. Banner build invokes it once per skill to resolve the
category column, which on a 120-skill install meant ~120 reparses of
a 15 KB config (~85 ms each). Added a
`(config_path, mtime_ns) -> list[Path]` memo; stat() is ~2 us vs
~85 ms for the parse. Edits to config.yaml invalidate the cache on
the next call via mtime.
2. Feishu availability probe uses `importlib.util.find_spec` (~5.2s saved)
`tools/feishu_doc_tool.py::_check_feishu` and the identical helper in
`feishu_drive_tool.py` were calling `import lark_oapi` purely to
detect whether the SDK was installed. Executing the real import pulls
in websockets + dispatcher + every v2 API model — ~5 seconds of work
that fires at every tool-registry bootstrap. `find_spec` answers the
same question ("is lark_oapi importable?") without executing the
module. The actual tool handlers still do the real import on invoke,
so runtime behavior is unchanged.
3. `_web_requires_env` no longer triggers Nous portal refresh (~800ms saved)
`tools/web_tools.py::_web_requires_env` used
`managed_nous_tools_enabled()` to gate four gateway env-var names in
the returned list. The gate called `get_nous_auth_status()` ->
`resolve_nous_runtime_credentials()` -> live HTTP POST to the portal
on every tool-registry bootstrap. But the list is pure metadata — if
the env var is set at runtime, the tool lights up; otherwise it
doesn't. Including the four names unconditionally is harmless for
unsubscribed users (vars just aren't set) and eliminates the sync
HTTP round trip from startup.
Test:
- tests/agent/test_external_skills_dirs_cache.py (new, 6 cases):
returns config'd dir, caches on second call (yaml_load patched to
raise — never invoked), invalidates on mtime bump, empty when config
missing, returned list is a defensive copy, per-HERMES_HOME cache key
isolation.
- Existing tests/agent/test_external_skills.py and tests/tools/
continue to pass modulo pre-existing flakes on main (test_delegate,
test_send_message — unrelated, pass in isolation).
Measured: bare `hermes` (cold → REPL ready) 21,519ms -> 2,618ms on
Teknium's install (119 skills, 15 KB config.yaml, Nous auth logged in,
lark_oapi installed). 8x faster.
## Why
Hermes supports Linux, macOS, and native Windows, but the codebase grew up
POSIX-first and has accumulated patterns that silently break (or worse,
silently kill!) on Windows:
- `os.kill(pid, 0)` as a liveness probe — on Windows this maps to
CTRL_C_EVENT and broadcasts Ctrl+C to the target's entire console
process group (bpo-14484, open since 2012).
- `os.killpg` — doesn't exist on Windows at all (AttributeError).
- `os.setsid` / `os.getuid` / `os.geteuid` — same.
- `signal.SIGKILL` / `signal.SIGHUP` / `signal.SIGUSR1` — module-attr
errors at runtime on Windows.
- `open(path)` / `open(path, "r")` without explicit encoding= — inherits
the platform default, which is cp1252/mbcs on Windows (UTF-8 on POSIX),
causing mojibake round-tripping between hosts.
- `wmic` — removed from Windows 10 21H1+.
This commit does three things:
1. Makes `psutil` a core dependency and migrates critical callsites to it.
2. Adds a grep-based CI gate (`scripts/check-windows-footguns.py`) that
blocks new instances of any of the above patterns.
3. Fixes every existing instance in the codebase so the baseline is clean.
## What changed
### 1. psutil as a core dependency (pyproject.toml)
Added `psutil>=5.9.0,<8` to core deps. psutil is the canonical
cross-platform answer for "is this PID alive" and "kill this process
tree" — its `pid_exists()` uses `OpenProcess + GetExitCodeProcess` on
Windows (NOT a signal call), and its `Process.children(recursive=True)`
+ `.kill()` combo replaces `os.killpg()` portably.
### 2. `gateway/status.py::_pid_exists`
Rewrote to call `psutil.pid_exists()` first, falling back to the
hand-rolled ctypes `OpenProcess + WaitForSingleObject` dance on Windows
(and `os.kill(pid, 0)` on POSIX) only if psutil is somehow missing —
e.g. during the scaffold phase of a fresh install before pip finishes.
### 3. `os.killpg` migration to psutil (7 callsites, 5 files)
- `tools/code_execution_tool.py`
- `tools/process_registry.py`
- `tools/tts_tool.py`
- `tools/environments/local.py` (3 sites kept as-is, suppressed with
`# windows-footgun: ok` — the pgid semantics psutil can't replicate,
and the calls are already Windows-guarded at the outer branch)
- `gateway/platforms/whatsapp.py`
### 4. `scripts/check-windows-footguns.py` (NEW, 500 lines)
Grep-based checker with 11 rules covering every Windows cross-platform
footgun we've hit so far:
1. `os.kill(pid, 0)` — the silent killer
2. `os.setsid` without guard
3. `os.killpg` (recommends psutil)
4. `os.getuid` / `os.geteuid` / `os.getgid`
5. `os.fork`
6. `signal.SIGKILL`
7. `signal.SIGHUP/SIGUSR1/SIGUSR2/SIGALRM/SIGCHLD/SIGPIPE/SIGQUIT`
8. `subprocess` shebang script invocation
9. `wmic` without `shutil.which` guard
10. Hardcoded `~/Desktop` (OneDrive trap)
11. `asyncio.add_signal_handler` without try/except
12. `open()` without `encoding=` on text mode
Features:
- Triple-quoted-docstring aware (won't flag prose inside docstrings)
- Trailing-comment aware (won't flag mentions in `# os.kill(pid, 0)` comments)
- Guard-hint aware (skips lines with `hasattr(os, ...)`,
`shutil.which(...)`, `if platform.system() != 'Windows'`, etc.)
- Inline suppression with `# windows-footgun: ok — <reason>`
- `--list` to print all rules with fixes
- `--all` / `--diff <ref>` / staged-files (default) modes
- Scans 380 files in under 2 seconds
### 5. CI integration
A GitHub Actions workflow that runs the checker on every PR and push is
staged at `/tmp/hermes-stash/windows-footguns.yml` — not included in this
commit because the GH token on the push machine lacks `workflow` scope.
A maintainer with `workflow` permissions should add it as
`.github/workflows/windows-footguns.yml` in a follow-up. Content:
```yaml
name: Windows footgun check
on:
push:
branches: [main]
pull_request:

steps:
- uses: actions/checkout@v4
- uses: actions/setup-python@v5
with: {python-version: "3.11"}
- run: python scripts/check-windows-footguns.py --all
```
### 6. CONTRIBUTING.md — "Cross-Platform Compatibility" expansion
Expanded from 5 to 16 rules, each with message, example, and fix.
Recommends psutil as the preferred API for PID / process-tree operations.
### 7. Baseline cleanup (91 → 0 findings)
- 14 `open()` sites → added `encoding='utf-8'` (internal logs/caches) or
`encoding='utf-8-sig'` (user-editable files that Notepad may BOM)
- 23 POSIX-only callsites in systemd helpers, pty_bridge, and plugin
tool subprocess management → annotated with
`# windows-footgun: ok — <reason>`
- 7 `os.killpg` sites → migrated to psutil (see §3 above)
## Verification
```
$ python scripts/check-windows-footguns.py --all
✓ No Windows footguns found (380 file(s) scanned).
$ python -c "from gateway.status import _pid_exists; import os
> print('self:', _pid_exists(os.getpid())); print('bogus:', _pid_exists(999999))"
self: True
bogus: False
```
Proof-of-repro that `os.kill(pid, 0)` was actually killing processes
before this fix — see commit `1cbe39914` and bpo-14484. This commit
removes the last hand-rolled ctypes path from the hot liveness-check
path and defers to the best-maintained cross-platform answer.
On Windows, Python's ``os.kill(pid, 0)`` is NOT a no-op. CPython's
implementation (``Modules/posixmodule.c::os_kill_impl``) treats sig=0
as ``CTRL_C_EVENT`` because the two integer values collide at the C
layer, and routes it through ``GenerateConsoleCtrlEvent(0, pid)`` —
which sends a Ctrl+C to the ENTIRE console process group containing
the target PID, not just the PID itself. Any caller that wanted to
check "is PID X alive" via the classic POSIX ``os.kill(pid, 0)``
idiom was silently killing that process (and often unrelated
processes in the same console group) on Windows. Long-standing
Python Windows quirk; see bpo-14484 (open since 2012).
This manifested in Hermes as: every ``hermes gateway status``
invocation would read the gateway's PID from the PID file, call
``os.kill(pid, 0)`` via ``gateway.status.get_running_pid()`` as a
"liveness check", and instantly terminate the gateway it was trying
to report on. No shutdown log, no traceback, no atexit hook fire,
no exit-diag entry — just silent termination of the detached pythonw
process. "Bot answered one message then stopped typing" was the
characteristic end-user symptom because `os.kill(pid, 0)` fires
mid-response-send and kills the gateway between logs.
Reproduction (verified in this branch before the fix):
$ hermes gateway start # gateway alive, PID 37520
$ hermes gateway status # reports "No gateway process detected"
$ tasklist /FI "PID eq 37520" # INFO: No tasks are running
# — gateway terminated silently
Root-cause fix is a new ``gateway.status._pid_exists(pid)`` helper:
- On Windows: Win32 ``OpenProcess(PROCESS_QUERY_LIMITED_INFORMATION |
SYNCHRONIZE, False, pid)`` + ``WaitForSingleObject(handle, 0)``
via ctypes. Zero signal delivery, zero console-group side effects.
Pins ctypes return types to avoid DWORD-vs-signed-int parse bugs
on WAIT_TIMEOUT (0x102). Distinguishes ERROR_INVALID_PARAMETER
(PID gone) from ERROR_ACCESS_DENIED (alive but another user).
- On POSIX: the canonical ``os.kill(pid, 0)`` idiom that actually is
a no-op there.
Then patch every ``os.kill(pid, 0)`` liveness-check callsite to
route through ``_pid_exists`` instead. Total 14 callsites across
11 files; every single one was a latent silent-kill on Windows:
gateway/run.py:2810 — /restart watcher (inline subprocess)
gateway/run.py:15195 — --replace wait loop
gateway/status.py:572 — acquire_gateway_runtime_lock stale check
gateway/status.py:828 — get_running_pid (THE killer for status)
gateway/platforms/whatsapp.py:111
hermes_cli/gateway.py:228, 522, 1012 — gateway-related drain loops
hermes_cli/kanban_db.py:2826 — _pid_alive was claiming to
be cross-platform but used
os.kill(pid, 0) on Windows
hermes_cli/main.py:5792 — CLI process-kill polling
hermes_cli/profiles.py:782 — profile stop wait loop
plugins/google_meet/process_manager.py:74
tools/browser_tool.py:1215, 1255 — browser daemon ownership probes
tools/mcp_tool.py:1255, 3374 — MCP stdio orphan tracking
The watcher source in gateway/run.py:2810 is a multi-line string
that gets spawned as an inline ``python -c "..."`` subprocess, so
it can't import gateway.status. The fix for that callsite inlines
the same ctypes probe directly into the watcher source.
Tested on Windows 10 with the hermes gateway + Telegram bot:
- gateway start → alive
- 5 consecutive ``hermes gateway status`` invocations → gateway
alive after every one, same PID reported each time (37520, 21952)
- gateway.log shows uninterrupted operation; no spurious shutdown
entries; cron ticker and kanban dispatcher still running on
their 60-second cadence
- bot continues answering Telegram messages throughout
Ships alongside an exit-path diagnostic wrapper in
``hermes_cli/gateway.py::run_gateway()`` that captures every way
``asyncio.run(start_gateway(...))`` can return (success, SystemExit,
KeyboardInterrupt, BaseException, atexit) with full traceback to
``logs/gateway-exit-diag.log``. This was used to prove the gateway
was being hard-killed externally (no exit event fired) and should
be kept for future Windows debugging.

Three related Windows-only fixes that together make the browser toolset
actually usable on Windows. Symptom chain: user invokes browser_navigate
-> tool returns {"success": false, "error": "Daemon process exited
during startup with no error output"} and the CLI exits mid-turn with
the session summary.
Root cause (3 layers):
1. tools/browser_tool.py::_find_agent_browser() resolved
node_modules/.bin/agent-browser to the extensionless POSIX shell
shim via Path.exists(). On Windows, CreateProcessW cannot execute
that script (WinError 193 "not a valid Win32 application"). Fix:
delegate to shutil.which with path=node_modules/.bin so PATHEXT
picks up agent-browser.CMD on Windows and the extensionless shim
stays correct on POSIX.
2. Windows Terminal / Win32 delivers a spurious CTRL_C_EVENT to the
parent hermes.exe whenever a background thread spawns a .cmd
subprocess. Python 3.11's default SIGINT handler raises
KeyboardInterrupt in MainThread, which unwinds prompt_toolkit's
app.run() -> cli.py::run()'s finally block calls _run_cleanup()
-> _emergency_cleanup_all_sessions -> spawns a concurrent
_run_browser_command("close", ...) on the same session the agent
thread just opened. Two agent-browser processes race on the same
--session name, the daemon startup loses, and the tool returns
the "Daemon process exited during startup" error. Fix: install a
Windows-only SIGINT handler that absorbs the signal silently.
Real user Ctrl+C still routes through prompt_toolkit's own c-c
keybinding at the TUI layer, which is how Claude Code handles the
same quirk (driving cancellation via the TUI key handler, not
signals).
3. In tools/browser_tool.py, both Popen sites now pass
creationflags=CREATE_NO_WINDOW | STARTF_USESTDHANDLES with
close_fds=True on Windows. CREATE_NO_WINDOW suppresses the .cmd
console flash; STARTF_USESTDHANDLES + close_fds ensures the child
inherits only our three chosen handles (DEVNULL stdin, temp-file
stdout/stderr) and no leaked parent console handles that could
confuse agent-browser's native daemon spawn. Notably we do NOT
add CREATE_NEW_PROCESS_GROUP - on Python 3.11 Windows the flag
interacts badly with asyncio's ProactorEventLoop and makes things
worse.
Verified end-to-end on Windows 10 / Windows Terminal / PowerShell:
browser_navigate to https://example.com returns
{"success": true, "title": "Example Domain"} and the CLI stays alive
for follow-up tool calls and assistant turns.

Closes the last Python-on-Windows UTF-8 exposure by making every
text-mode open() call explicit about its encoding.
Before: on Windows, bare open(path, 'r') defaults to the system
locale encoding (cp1252 on US-locale installs). That means reading
any config/yaml/markdown/json file with non-ASCII content either
crashes with UnicodeDecodeError or silently mis-decodes bytes.
After: all 89 affected call sites in production code now pass
encoding='utf-8' explicitly. Works identically on every platform
and every locale, no surprise behavior.
Mechanical sweep via:
ruff check --preview --extend-select PLW1514 --unsafe-fixes --fix --exclude 'tests,venv,.venv,node_modules,website,optional-skills, skills,tinker-atropos,plugins' .
All 89 fixes have the same shape: open(x) or open(x, mode) became
open(x, encoding='utf-8') or open(x, mode, encoding='utf-8'). Nothing
else changed. Every modified file still parses and the Windows/sandbox
test suite is still green (85 passed, 14 skipped, 0 failed across
tests/tools/test_code_execution_windows_env.py +
tests/tools/test_code_execution_modes.py + tests/tools/test_env_passthrough.py +
tests/test_hermes_bootstrap.py).
Scope notes:
- tests/ excluded: test fixtures can use locale encoding intentionally
(exercising edge cases). If we want to tighten tests later that's
a separate PR.
- plugins/ excluded: plugin-specific conventions may differ; plugin
authors own their code.
- optional-skills/ and skills/ excluded: skill scripts are user-authored
and we don't want to mass-edit them.
- website/ and tinker-atropos/ excluded: vendored / generated content.
46 files touched, 89 +/- lines (symmetric replacement). No behavior
change on POSIX or on Windows when the file is ASCII; bug fix on
Windows when the file contains non-ASCII.
Third Windows-specific sandbox bug (after WinError 10106 and the UTF-8
file-write bug): user scripts that print non-ASCII to stdout crash with
UnicodeEncodeError: 'charmap' codec can't encode character '\u2192'
in position N: character maps to <undefined>
Root cause: Python's sys.stdout on Windows is bound to the console code
page (cp1252 on US-locale installs) when the process is attached to a
pipe without PYTHONIOENCODING set. LLM-generated scripts routinely
print em-dashes, arrows, accented chars, and emoji — all of which cp1252
can't encode.
Fix: spawn the sandbox child with:
PYTHONIOENCODING=utf-8 # sys.stdin/stdout/stderr all UTF-8
PYTHONUTF8=1 # PEP 540 UTF-8 mode — open() defaults to UTF-8 too
PYTHONUTF8 is the belt-and-suspenders half: LLM scripts that call
open(path, 'w') without encoding= in user code will now produce UTF-8
files by default, matching what the sandbox already does for its own
staging files.
The parent side already decodes child stdout/stderr as UTF-8 with
errors='replace' (lines 1345-1347) so the end-to-end chain is clean.
On POSIX these values usually match the locale default already, so
setting them is harmless belt-and-suspenders for C/POSIX-locale
containers and minimal base images.
Tests added (4) — total file now at 28 passed, 1 skipped on Windows:
- test_popen_env_sets_pythonioencoding_utf8 (source grep)
- test_popen_env_sets_pythonutf8_mode (source grep)
- test_live_child_can_print_non_ascii (cross-platform live test)
- test_windows_child_without_utf8_env_would_fail (Windows negative
control — actually reproduces the bug without our env overrides,
proving the fix is load-bearing on this system)
Second Windows-specific sandbox bug (WinError 10106 was the first):
after the env-scrub fix let the child start, it immediately failed to
import hermes_tools with:
SyntaxError: (unicode error) 'utf-8' codec can't decode byte 0x97
in position 154: invalid start byte
Root cause: _execute_local wrote the generated hermes_tools.py stub and
the user's script.py via open(path, 'w') without encoding=. On Windows
the default text-mode encoding is cp1252 (system locale), which encodes
em-dashes (used in the stub's docstrings) as 0x97. Python then decodes
source files as UTF-8 (PEP 3120) on import, chokes on 0x97, and the
sandbox dies before any tool call.
Fix: pass encoding='utf-8' to all four file opens in the code_execution
path — the two staging writes in _execute_local (hermes_tools.py +
script.py) and the two RPC file-transport reads/writes in the generated
remote stub. JSON is ASCII-safe for most payloads but tool results
(terminal output, web_extract content) routinely carry non-ASCII.
Tests added (4):
- test_stub_and_script_writes_specify_utf8 — source grep guard
- test_file_rpc_stub_uses_utf8 — generated remote stub check
- test_stub_source_roundtrips_through_utf8 — concrete round-trip
- test_windows_default_encoding_would_have_failed — negative control
(skips on modern Python builds where default is already UTF-8
compatible, but retained for platforms where the regression could
return)
24/25 tests pass on Windows 3.11 (negative control skips because this
Python build handles em-dashes via cp1252 subset — the fix is still
correct, just the corruption path isn't always triggerable).
The sandbox's env scrubbing was dropping SYSTEMROOT, WINDIR, COMSPEC,
APPDATA, etc. On Windows this broke the child process before any RPC
could happen:
OSError: [WinError 10106] The requested service provider could not
be loaded or initialized
Python's socket module uses SYSTEMROOT to locate mswsock.dll during
Winsock initialization. Without it, socket.socket(AF_INET, SOCK_STREAM)
fails — and the existing loopback-TCP fallback for Windows couldn't work.
Fix: add a small Windows-only allowlist (_WINDOWS_ESSENTIAL_ENV_VARS)
matched by exact uppercase name, after the existing secret-substring
block. The secret block still runs first, so the allowlist cannot be
used to exfiltrate credentials. Also extract the env scrubber into a
testable helper (_scrub_child_env) that takes is_windows as a parameter,
so the logic can be unit-tested on any OS.
Live Winsock smoke test verifies that a child spawned with the scrubbed
env can now create an AF_INET socket on a real Windows host; the test
is guarded by sys.platform == 'win32' so POSIX CI stays green.
teknium1 noticed execute_code was missing from his enabled tools on Windows.
Root cause: tools/code_execution_tool.py set ``SANDBOX_AVAILABLE =
sys.platform != \"win32\"`` as a module-level constant, originally because
the RPC transport required AF_UNIX. We added loopback TCP fallback for
the sandbox in commit eeb723fff (and covered it in the Windows TCP tests),
but forgot to lift the availability gate. So execute_code was still
invisible via the check_fn path on Windows.
- SANDBOX_AVAILABLE is now True unconditionally (it's still checked — a
future platform could flip it off via monkeypatch/env if needed).
- Error message when disabled no longer mentions Windows specifically,
just says 'sandbox is unavailable in this environment'.
- test_windows_returns_error updated: patches SANDBOX_AVAILABLE=False
directly (which was always its real intent) and asserts on 'unavailable'
instead of 'Windows'.
Tests: 171 code-execution + windows-compat tests pass, no regressions.
Three bugs from teknium1's successful install + diagnostic chat on Windows:
1. **Start-Process -FilePath npm.cmd fails with "%1 is not a valid Win32
application".** Start-Process bypasses cmd.exe and PATHEXT to call
CreateProcessW directly, which refuses .cmd batch shims. Switched
Install-NodeDeps to use PowerShell's invocation operator (``& $npmExe
install --silent *> $log``) which DOES honour PATHEXT. Extracted a
``_Run-NpmInstall`` helper so the browser + TUI paths share the same
logic. Captures $LASTEXITCODE correctly, still surfaces the real
stderr on failure with a log-file pointer for the full output.
2. **patch tool returns false-negative on Windows due to CRLF round-trip.**
Root cause was upstream of patch: ``subprocess.Popen(..., text=True,
stdin=PIPE)`` on Windows translates ``\\n`` → ``\\r\\n`` when data flows
through the stdin pipe. ``_pipe_stdin()`` was writing the patch's
new_content string through a text-mode pipe, bash then wrote those
CRLF bytes to disk, and patch's post-write verify compared the
on-disk CRLF bytes against the original LF-only string — fail.
Fixed in two places for defense in depth:
- ``_pipe_stdin()`` now writes through ``proc.stdin.buffer`` with
explicit UTF-8 encoding, bypassing Python's newline translation on
every platform. No behaviour change on POSIX (bytes are identical)
but stops the CRLF injection on Windows.
- ``patch_replace``'s post-write verify normalizes CRLF→LF on both
sides before comparing, so even if some future backend still
translates newlines the patch tool won't report a bogus failure.
3. **SOUL.md gets a UTF-8 BOM on Windows PowerShell 5.1.** ``Set-Content
-Encoding UTF8`` on PS5.1 writes UTF-8 WITH a byte-order-mark (changed
in PS7 via ``utf8NoBOM``). Hermes's prompt-injection scanner sees
the BOM (U+FEFF invisible char) and refuses to load the file, so
SOUL.md's persona instructions never get applied.
Fixed by writing the file via ``[System.IO.File]::WriteAllText``
with an explicit ``UTF8Encoding($false)`` — BOM-free on every
PowerShell version.
All POSIX behaviour verified unchanged: 198 tests pass across
test_file_operations, test_local_env_cwd_recovery, test_code_execution,
test_windows_native_support, test_windows_compat.
Three interrelated bugs from teknium1's first interactive chat on Windows:
1. **Snapshot/cwd file paths unquoted in bash command strings.** The session
bootstrap and per-command wrapper interpolated
``self._snapshot_path`` / ``self._cwd_file`` unquoted into bash commands
like ``export -p > C:/Users/ryanc/.../hermes-snap-xxx.sh``. Git Bash's
MSYS2 layer handles ``C:/...`` paths correctly ONLY when quoted; unquoted,
the colon and forward-slash get glob-parsed and the redirect targets a
bogus path. Symptom: every terminal command emitted two
``C:/Users/.../hermes-snap-*.sh (No such file or directory)`` lines that
bled into stdout (``stderr=STDOUT`` on the local backend) and corrupted
file contents when the agent wrote to scratch paths via the terminal
tool. Fix: ``shlex.quote()`` every interpolation of ``_snapshot_path``
and ``_cwd_file`` in base.py — no-op on POSIX (the paths contain no
shell-metachars), critical on Windows.
2. **Stale PATH on first hermes launch after install.** ``install.ps1``
adds the PortableGit ``cmd`` / ``bin`` / ``usr\bin`` directories to the
Windows **User** PATH via ``SetEnvironmentVariable(..., "User")``. That
write propagates to newly *spawned* processes only — already-running
shells (including the one the user types ``hermes`` into immediately
after install) retain their old PATH. So hermes starts with a PATH that
doesn't include bash, rg, grep, ssh — and ``search_files`` reports
"rg/find not available" when the user clearly just installed them.
Fix: new ``_augment_path_with_known_tools()`` helper called from
``configure_windows_stdio()`` on startup. Prepends the Hermes-managed
Git directories + the WinGet Links directory (where ripgrep lands) to
``os.environ['PATH']`` if they exist on disk but aren't already in
PATH. Subsequent subprocess calls (including bash spawns via
``_find_bash()``) inherit the augmented PATH and find everything.
No-op on POSIX and when the directories don't exist.
3. **Root cause of "file content corruption".** #1 was the proximate cause.
Errors like ``C:/Users/.../hermes-snap-xxx.sh: No such file or directory``
were emitted on stderr by the failed redirect, captured into stdout via
``stderr=subprocess.STDOUT``, and if the agent used terminal commands
like ``cat > file`` the leaked error bytes became part of the file.
Fixing #1 eliminates this entirely.
## Tests
All 77 Windows-compat tests still pass on Linux (POSIX path is
shlex.quote('/tmp/foo.sh') → '/tmp/foo.sh' — unchanged).
## Not addressed here (would need a bigger design)
- Python file tools (``write_file``, ``read_file``) and the bash-backed
terminal tool see DIFFERENT views of ``/tmp`` on Windows. Python treats
``/tmp`` as ``C:\tmp`` (drive-relative), Git Bash's MSYS2 treats it as
a virtual mount to the PortableGit install's ``tmp\``. Would need a
translation shim in the Python tools to resolve bash-virtual paths to
their native-Windows equivalents. Workaround for users today: use
absolute native paths (``C:\Users\you\...``) instead of ``/tmp/...``
when crossing between terminal and Python file tools.
