## Summary
The background skill/memory-review fork constructed a child `AIAgent`
without propagating `enabled_toolsets` / `disabled_toolsets` from the
parent. When the parent narrowed its toolset (via `hermes tools
disable` or `config.yaml`), the fork's default `enabled_toolsets=None`
expanded to "all registered tools" — and the fork's outbound request
body sent a wider `tools[]` array than the parent's main-turn request.
Anthropic's prompt-cache key includes the `tools[]` array byte-for-byte,
so this divergence forked the cache lineage on every nudge and forced a
full prefix rewrite. On a captured ~4 hour Claude-via-Hermes session
this cost roughly 4.3 M cache-write tokens — about half of those
attributable to the per-nudge alternation between the main turn's
narrowed `tools[]` and the review fork's wider `tools[]`.
## Goal
Extend the byte-stability invariant established by PR #17276 (which
fixed `system`) to the `tools[]` slot of the request body, so the
review fork's outbound request hits the parent's warmed Anthropic
prefix cache regardless of how the parent's toolset is configured.
## Implementation
Two-line change in `agent/background_review.py`: pass
`enabled_toolsets=getattr(agent, "enabled_toolsets", None)` and the
matching `disabled_toolsets` kwarg into the `AIAgent(...)` call inside
`_spawn_background_review`. Adds an explanatory block comment that
calls out the cache-key dependency and the relationship to PR #17276.
The post-construction runtime whitelist
(`set_thread_tool_whitelist({memory, skills})`) is untouched — it
still gates which tools the model is allowed to *dispatch*. This
change aligns only what the request body *transmits*, not what the
review is allowed to do, so the safety contract from issue #15204
remains intact.
## Testing
- `tests/run_agent/test_background_review_cache_parity.py`: new
`test_review_fork_inherits_parent_toolset_config` asserts the
parent's `enabled_toolsets` and `disabled_toolsets` reach the
review-fork constructor as kwargs.
- `tests/run_agent/test_background_review_toolset_restriction.py`:
the existing `test_background_review_does_not_narrow_toolset_schema`
was inverted (its old "must NOT pass enabled_toolsets" rule was
built on the assumption that the parent always ran with the
registry default — wrong in practice when the parent is narrowed).
Renamed to `test_background_review_matches_parent_toolset_config`
and updated to assert the parent's value propagates verbatim.
- Verified the new positive test fails without the fix and passes
with it.
- Full suite for `test_background_review*`:
```
$ python -m pytest tests/run_agent/test_background_review.py \

18 passed in 1.85s
```
## Scope
- `agent/background_review.py`: 2 added kwargs + explanatory comment.
- Two test files: one new positive test, one inverted existing test.
- No production code paths outside the review fork; no schema changes;
no public-API changes.

_handle_location_message and _handle_media_message were skipped when the
observe-unmentioned-group-messages feature landed (a9db0e2c7). Both handlers
now:
1. Check _should_observe_unmentioned_group_message on the skipped path and
call _observe_unmentioned_group_message so group chatter is stored as
shared session context even when the bot is not addressed.
2. Call _apply_telegram_group_observe_attribution on the triggered path so
the dispatched event uses the shared (user_id=None) group session instead
of the per-user session, letting the model see previously observed context.
For stickers the attribution is applied after _handle_sticker completes
(which overwrites event.text with the vision description); for all other
media types it is applied once after caption cleaning.
Four new tests cover the observe and attribution paths for both handlers.
build_write_denied_paths() resolved the protected ``.env`` via
get_hermes_home(), which is profile-aware. When a profile is active
HERMES_HOME points at ``<root>/profiles/<name>`` and ``hermes_home / ".env"``
expands to the *profile* env file only — the global ``<root>/.env`` is left
off the deny list and a write_file call against it succeeds. Since the
top-level .env supplies credentials inherited by every profile, this is a
P0 credential-exfiltration / overwrite path.
Add a parallel ``_hermes_root_path()`` helper that returns the Hermes root
(via the existing ``get_default_hermes_root()`` constant) and include
``<root>/.env`` in the deny list alongside ``<active_profile>/.env``. Both
paths now refuse write_file/patch regardless of profile state. The active
HERMES_HOME .env entry is preserved so the protection in non-profile mode
is unchanged.
A regression test exercises the profile-active scenario by pointing
HERMES_HOME at ``<tmp>/profiles/coder`` and asserting that ``<tmp>/.env``
is denied.
Fixes#15981
The typing indicator loop (send_typing) ran every 8s and died on any
exception, including Discord 429 rate limits. Once a 429 killed the
loop, the indicator never restarted — and the raw exception bounce
could cascade into broader gateway instability.
Changes:
- Bump sleep interval from 8s to 12s (typing light lasts ~10s)
- On 429: extract retry_after, log a warning, sleep the backoff,
and continue the loop
- On non-rate-limit errors: log debug and return (unchanged
behaviour)
The interactive CLI input path consults decide_image_input_mode() to pick
between native image_url attachment and the vision_analyze text pipeline,
but the non-interactive 'hermes chat -Q -q ... --image FOO' path
unconditionally called _preprocess_images_with_vision() — so even with
`model.supports_vision: true` set, --image always went through the
text-pipeline. Symptom: vision_analyze runs 4-5s per image and the model
sees a lossy text summary instead of the actual pixels.
Mirror the interactive path: load config, call decide_image_input_mode,
branch on native vs text. Falls back to the text-pipeline on any import
or build error (Pyright-clean: _build_parts guarded with `is not None`).

Same model, same image, single knob flips text→native routing.
The contributor PR (#17936) only patched the strip path in
`_model_supports_vision()`. The auto-mode router in
`agent/image_routing._lookup_supports_vision` still only read models.dev,
so a custom-provider model declared as vision-capable would still get its
images routed through vision_analyze in the default `agent.image_input_mode:
auto` setting. Users had to set both `supports_vision: true` AND
`image_input_mode: native` to bypass the text pipeline.
Single-knob behavior now: `supports_vision: true` alone is enough in auto
mode. The strip path and the routing path consult the same resolver.
- Extract override resolution into `_supports_vision_override()` in
agent/image_routing.py and wire it into `_lookup_supports_vision()`.
- Refactor `run_agent._model_supports_vision` to call the same helper
(DRY, single source of truth for the resolution order).
- Strict YAML boolean coercion: `supports_vision: "false"` (quoted —
a common YAML mistake) no longer coerces to True via bool() truthiness.
Recognised tokens: true/false/yes/no/on/off/1/0 plus real bools and 0/1.
Unrecognised values return None and fall through to models.dev.
- Add @CNSeniorious000 to AUTHOR_MAP for release attribution.
Tests: 26 new (TestCoerceCapabilityBool, TestSupportsVisionOverride,
TestLookupSupportsVisionOverride, TestAutoModeRespectsOverride). Existing
contributor tests + image_routing + vision_native_fast_path +
native_image_buffer_isolation all green (92/92).
Named custom providers are rewritten to provider="custom" at runtime
(hermes_cli/runtime_provider.py:_resolve_named_custom_runtime), so a
config under providers.my-vllm.models.my-llava.supports_vision was
unreachable via self.provider alone. Also try cfg.model.provider as a
candidate provider key, covering both runtime and config naming.
Adds a regression test for the named-provider path.
Custom/local provider models absent from models.dev get classified as
non-vision and have their image content stripped before reaching the
upstream API. Surface a user-facing override:
model:
supports_vision: true
providers:
my-vllm:
models:
my-llava:
supports_vision: true
The override short-circuits the models.dev lookup in
_model_supports_vision(), which is the single gate guarding image-strip
preprocessing on every transport path.

xAI partner integration requires Hermes to thread `encrypted_content`
reasoning items back to the Responses API on every turn so Grok can
maintain cross-turn reasoning coherence. PR #26644 (May 15) gated this
off for `is_xai_responses` on the theory that the OAuth/SuperGrok
surface rejected replayed encrypted blobs and produced the multi-turn
"Expected to have received \`response.created\` before \`error\`"
failure. That diagnosis was wrong — the prelude-SSE fallback added in
the same PR is what actually fixed that failure mode. Suppressing the
replay was an unnecessary side-effect that broke the whole point of
xAI's partnership integration.
Changes:
- agent/codex_responses_adapter.py — drop the `is_xai_responses` gate
in `_chat_messages_to_responses_input`. Keep the kwarg in the
signature for transport compatibility; update the docstring to
document the May 2026 reversal.
- agent/transports/codex.py — restore
`kwargs["include"] = ["reasoning.encrypted_content"]` on the xAI
Responses path so xAI echoes encrypted reasoning back to us.
- tests/run_agent/test_codex_xai_oauth_recovery.py — flip the three
xAI assertions (now: xAI MUST receive replayed reasoning AND we MUST
include encrypted_content in the request).
- tests/agent/transports/test_codex_transport.py — flip the
`include` assertions on `test_xai_reasoning_effort_passed` and
`test_xai_grok_4_omits_reasoning_effort`; update the allowlist
block comment.
The prelude-SSE fallback and the entitlement-403 surfacing fixes from
#26644 are untouched — they were independent fixes that happened to
ride along with the reasoning-replay gate.
Validation:
- Targeted: tests/run_agent/test_codex_xai_oauth_recovery.py +
tests/agent/transports/test_codex_transport.py → 65/65 pass
- Broader: tests/agent/transports/ + tests/run_agent/ →
1674 passed, 3 skipped, 0 failures
- E2E (real imports, isolated HERMES_HOME, ResponsesApiTransport
build_kwargs): turn-1 request carries
`include: ["reasoning.encrypted_content"]`; turn-2 input replays
the encrypted_content blob from turn-1's
`codex_reasoning_items`; native Codex unchanged.
Five call sites do os.chmod(path.parent, 0o700) without checking that
the parent resolves to a safe directory. If HERMES_HOME or another
path env var resolves to /, the chmod strips traversal permission from
the root inode and bricks the entire host.
Add secure_parent_dir() to hermes_constants.py that refuses to chmod
/ or any top-level directory (depth < 2). Replace all 5 call sites
with this helper.
Fixes#25821
After #28660's host-gating fix, users with provider=custom and base_url
pointed at a commercial endpoint (DeepSeek, Groq, Mistral, …) hit
no-key-required even when they had the vendor-named env var set
(DEEPSEEK_API_KEY, GROQ_API_KEY, …). The issue author flagged this as
'what users intuitively expect'.
Adds _host_derived_api_key() to derive an env var name from the base URL
host using the *registrable* label (second-to-last). Appended to all three
api_key_candidates chains (_resolve_named_custom_runtime direct-alias path,
named-custom path, _resolve_openrouter_runtime non-openrouter branch).
Lookalike resistance: api.deepseek.com.attacker.test resolves to vendor
label 'attacker', NOT 'deepseek' — DEEPSEEK_API_KEY stays put. IPs and
loopback yield no vendor label. Already-handled vendors (OPENAI/OPENROUTER/
OLLAMA) are filtered to prevent bypass of the explicit host-gated paths.
Adds 6 tests covering positive paths (DeepSeek, Groq), the lookalike attack,
loopback rejection, the already-handled-vendor filter, and direct helper
unit tests.
Also adds erhnysr to AUTHOR_MAP.
- Preserve OPENROUTER_API_KEY for explicit mirror/proxy configs when
requested provider is openrouter and OPENROUTER_BASE_URL is set
- Gate OPENAI_API_KEY and OPENROUTER_API_KEY in named custom provider
path (_resolve_named_custom_runtime) on authoritative hosts
- Gate same keys in direct-alias path
- Update tests to reflect secure-by-default behavior for local endpoints
Custom endpoint provider was forwarding OPENAI_API_KEY and OLLAMA_API_KEY
to arbitrary hosts. Keys should only be sent to their authoritative domains
(openai.com, ollama.com) or when explicitly configured via pool/env.
- Gate OPENAI_API_KEY to openai.com hosts only
- Gate OLLAMA_API_KEY to ollama.com hosts only
- Return 'no-key-required' for unrecognized custom endpoints
- Update tests to reflect secure-by-default behavior

`probeLinuxCopy` and `copyNative` in `osc.ts` await `execFileNoThrow`
for wl-copy / xclip / xsel. Those tools double-fork a daemon that
holds the system selection live, and the daemon inherits stdio pipes
from `spawn(stdio: 'pipe')`. Node's 'close' event only fires when
stdio is fully closed → the daemon keeps the pipes open → 'close'
never fires → the await leaks past the timeout (kill(SIGTERM) on an
already-exited child is a no-op, daemon survives).
Result: `linuxCopy` cache stays `undefined` permanently, the actual
copy never runs, ctrl-c silently does nothing on wayland/x11.
Reproduced in isolation, confirmed across wl-copy and a
daemonization-shaped fixture.
Fix: add `resolveOnExit` option to `execFileNoThrow`. When set, the
promise settles on the immediate child's 'exit' event instead of
waiting for stdio drainage. Wired into both the probe and the actual
copy spawns for every clipboard tool (pbcopy, wl-copy, xclip, xsel,
clip).
Tests: 5 new vitest cases covering daemon-style child handling,
non-zero exit propagation, timeout behavior, and double-resolve
guard. The forever-hang case is committed as `it.skip` with
documentation so a reviewer can verify the bug by hand.

- tools/skills_hub.py GitHubSource.search() had the same r.name dedup bug.
Two configured GitHub taps publishing same-named skills would collapse to one.
- tests/hermes_cli/test_skills_hub.py:test_browse_skills_dedup_uses_identifier_not_name
patched hermes_cli.skills_hub.create_source_router, but browse_skills() imports
it locally from tools.skills_hub. Fixed patch path.
browse_skills() is the TUI gateway's API for the web UI skills browser
(tui_gateway/server.py:6574). It had the same dedup-by-name bug as
do_browse() and unified_search() fixed in the parent commit: r.name is
not unique for browse-sh skills (Airbnb, Booking.com, Zillow all publish
"search-listings"), so the dedup loop silently dropped all but the first
skill with each task name.
Switch to r.identifier, which is always globally unique.
Add a regression test asserting that two browse-sh skills with the same
name but different hostnames both appear in the browse_skills() result.
Browse.sh exposes skills by task name (e.g. "search-listings"), which is
shared across hundreds of sites. Deduplicating by name silently dropped
every browse-sh skill after the first one with a given task name — e.g.
only Airbnb's "search-listings" would survive, collapsing Booking.com,
Zillow, and every other site's variant into nothing.
Switch unified_search() and do_browse() to use r.identifier as the dedup
key. identifier is always globally unique (e.g.
"browse-sh/airbnb.com/search-listings-ddgioa"), so same-named skills from
different browse-sh hostnames are preserved as distinct results.
Update existing TestUnifiedSearchDedup tests to model the real scenario
(same identifier appearing from two sources) and add a regression test
that asserts browse-sh skills with the same name but different hostnames
are never collapsed.
The xAI Responses API for x_search returns 200 OK with a
synthesized fluff answer in two failure modes that callers currently
cannot distinguish from a real, citation-backed result:
1. Any narrowing filter (allowed_x_handles, excluded_x_handles,
from_date, to_date) was active, but the X index returned no
matching posts. The model then answers from training data.
2. The date range is malformed, inverted, or pure-future (e.g.
from_date=2030-01-01). The API call burns quota and Grok
responds with a generic answer.
Mitigations, both client-side:
* Validate from_date / to_date before the HTTP call:
- Strict YYYY-MM-DD.
- from_date <= to_date when both set.
- from_date <= today UTC (no posts in a window that hasn't
started). to_date in the future remains allowed so callers
can request 'from yesterday to tomorrow'.
* Add 'degraded' + 'degraded_reason' to successful responses.
degraded=True iff any narrowing filter was active AND both the
top-level 'citations' array and inline 'url_citation'
annotations came back empty. A broad query with no filters that
returns no citations is *not* flagged degraded — that case is
just an unsourced answer, not a filter miss.
Tests cover all four validation paths plus six degraded-flag
scenarios (each filter type, inline vs top-level citation
recovery, broad query baseline). All existing tests continue to
pass; the additions are purely additive on the success-path
response shape.
Discovered while testing the x_search toolset end-to-end:
queries scoped to @Teknium1 returned confident-sounding generic
text about Nous Research with zero citations, and from_date in
2030 produced sassy non-answers. Both are now detectable by the
caller.
PR #29211 dropped JSONL gateway transcripts and noted that the platform's
own `message_id` field (used by Yuanbao's recall guard to redact a
message by exact platform id) was no longer preserved — falling back to
content-match. That fallback works for the common case but redacts the
wrong row when two messages share text (or fails to match when content
is post-processed).
Restore exact-id matching by giving state.db a column for it:
- New `platform_message_id TEXT` column on the messages table
(SCHEMA_VERSION bump 11 → 12; column added via declarative reconciler
on existing DBs, no version-gated migration block needed)
- Partial index `idx_messages_platform_msg_id` on
(session_id, platform_message_id) to keep recall's point-lookup cheap
even on large sessions
- `append_message()` and `replace_messages()` accept the new value:
the gateway-facing `append_to_transcript` in `gateway/session.py`
forwards either `message["platform_message_id"]` or the legacy
`message["message_id"]` key (yuanbao's existing convention)
- `get_messages_as_conversation()` surfaces the column back on the
message dict as `message_id` so platform code reads the same shape
it used to read from JSONL
- Yuanbao `_patch_transcript`: restore branch A1 (exact id match)
ahead of A2 (content match) ahead of B (system-note). Both branches
log which one fired so operators can tell from gateway.log whether
recall hit the canonical path or had to fall back.
Tests:
- New low-level round-trip tests in `test_hermes_state.py` for both
`append_message` and `replace_messages` paths
- The PR's `test_yuanbao_recall_db_only.py` was rewritten to assert
the new contract: branch A1 (id match) works against DB-only
transcripts, and branch A2 (content match) still recovers rows that
were observed without a platform id (e.g. agent-processed @bot
messages where run.py doesn't carry msg_id through)
PR #29211 review findings:
1. test_retry_replacement: pin DEFAULT_DB_PATH so SessionDB() doesn't write
to the real ~/.hermes/state.db. Same fix as the other DB-only fixtures.
2. yuanbao recall branch A1 (message_id exact match) was structurally dead
once load_transcript() became DB-only — state.db never preserves the
platform message_id. Removed the dead loop, consolidated to a single
content-match branch (renamed 'A: content match'). Branch B (system
note) unchanged. Updated the test name + docstring to reflect this.
Note: self._lock is no longer taken in append_to_transcript (was guarding
the JSONL file append). SQLite append_message handles its own concurrency
via WAL mode, so this is safe; flagging for awareness.
Fixtures that instantiate SessionStore() trigger SessionDB() with no args,
which resolves to ~/.hermes/state.db via the DEFAULT_DB_PATH module constant
(snapshot of get_hermes_home() at hermes_state import time).
The autouse _hermetic_environment fixture in tests/conftest.py monkeypatches
HERMES_HOME env, but DEFAULT_DB_PATH is already cached by then. Per-test
monkeypatch.setattr(hermes_state, 'DEFAULT_DB_PATH', tmp_path/'state.db')
forces the DB into tmp_path so the tests can't leak into the real profile.
Verified by counting u1-prefixed sessions in real state.db before/after:
delta=0.
Mirror messages are persisted via _append_to_sqlite. JSONL writer was
a redundant dual-write. Updated test assertions from JSONL file checks
to SQLite mock verification.
state.db is canonical. JSONL transcripts were a transition fallback;
the fallback was removed in the previous commit. Existing *.jsonl files
on disk are left untouched.
Yuanbao's recall feature was reading the gateway JSONL directly to look up
messages by platform message_id, which state.db does not preserve. Migrated
to use load_transcript() which returns DB messages.
Recall branch A1 (message_id match) now falls through to A2 (content match)
or B (system note) for all sessions — a documented degradation. Follow-up
issue: add platform_message_id column to state.db messages to restore
exact-id matching.
state.db is canonical. The 'use whichever source is longer' branch was
defensive code for the pre-DB migration; on every real DB it has not
fired (verified on a session corpus with 27 jsonl files / 950 sessions —
zero jsonl-bigger cases).
Test changes:
- TestLoadTranscriptCorruptLines: deleted (tested dead JSONL code path)
- TestLoadTranscriptPreferLongerSource: deleted (tested removed fallback)
- Replaced with TestLoadTranscriptDBOnly (DB-only reads)
- TestSessionStoreRewriteTranscript: fixture now creates DB session
- test_gateway_retry_replaces_last_user_turn: fixture uses real DB
* fix(deps): bump pydantic to 2.13.4 to avoid pydantic-core thread segfault
pydantic-core 2.41.5 (pulled by pydantic==2.12.5) segfaults when the
OpenAI SDK's Responses API resource (client.responses.create /
client.responses.stream) is exercised from a non-main threading.Thread.
Hermes always dispatches codex_responses calls from a daemon thread in
agent/chat_completion_helpers.py:_call, so the crash is 100%
reproducible whenever the active provider is xai-oauth or openai-codex.
Symptom: `hermes -z "ping"` (or any oneshot path) dies with SIGSEGV /
exit 139 and zero output — hermes_cli/oneshot.py redirects stderr to
/dev/null, hiding the crash.
Bumping pydantic to 2.13.4 pulls in pydantic-core 2.46.4, which
eliminates the crash. Verified end-to-end: `hermes -z "ping"` against
xai-oauth/grok-4.3 now returns the expected response.
Minimal repro (any OpenAI base_url; not xAI-specific):
import threading
from openai import OpenAI
cli = OpenAI(api_key="sk-bogus", base_url="https://api.openai.com/v1")
def go():
try: cli.responses.create(model="gpt-4o", input="ping")
except BaseException as e: print(type(e).__name__)
threading.Thread(target=go).start()
# → SIGSEGV with pydantic-core 2.41.5; clean 401 with 2.46.4
* chore(deps): regenerate uv.lock for pydantic 2.13.4 bump
`splitReasoning()` strips paired `<think>…</think>` blocks first, then runs
an unclosed-trailing regex to catch reasoning that hasn't yet streamed its
closer. That second regex was unanchored and greedy:
new RegExp(`<${tag}>([\\s\\S]*)$`, 'i')
So any literal `<think>` somewhere in prose — a model quoting the tag, a
code example, or a stream-mid-tag before the closer arrives — consumed
every paragraph after it to EOF. User-visible symptom: "TUI eats last
paragraph of output," both during streaming and on settled turns.
Real reasoning streams always lead the message (that's the only place an
unclosed opener can legitimately appear during streaming). Anchor the
regex to `^\s*` so mid-prose mentions of the tag are preserved.
Empirical repro before the fix:
splitReasoning('final answer paragraph one.\n\n<think>internal note\n\nfinal answer paragraph two.')
→ text: 'final answer paragraph one.' ← paragraph two GONE
After:
→ text: 'final answer paragraph one.\n\n<think>internal note\n\nfinal answer paragraph two.'
Updated the existing trailing-unclosed test to lead with `<think>` (the
real-world shape) and added a regression test pinning the mid-text case.
ui-tui type-check clean, 808/808 vitest pass.
PR #29182 deleted the per-session JSON snapshot writer outright because
state.db is canonical and the snapshots had no in-tree consumer. Some
users have external tooling that reads `~/.hermes/sessions/session_{sid}.json`
directly, so reintroduce the writer behind a config flag that defaults
to off.
- Add `sessions.write_json_snapshots` (default False) to DEFAULT_CONFIG
- Restore `AIAgent._save_session_log` + `_clean_session_content` as
gated methods. When the flag is off the call is a fast no-op; when
on, the writer behaves as before (atomic write, truncation guard
preserved, REASONING_SCRATCHPAD → think tag normalization)
- Re-derive the target path from `agent.session_id` on each call so
`/branch` and `/compress` re-points happen automatically — no need
to restore the explicit re-point bookkeeping at call sites
- Wire the single call site in `_persist_session` (the cleanup-on-exit
hook). Did NOT restore the 7 intra-turn calls the original PR deleted
— those were redundant writes within the same turn that doubled disk
I/O without adding any persistence guarantee `_persist_session` does
not already provide
- Read the flag once at agent init via `load_config()`, cache as
`agent._session_json_enabled`
- Update `TestNoSessionJsonSnapshot` → `TestSessionJsonSnapshotOptIn`
to pin behavior: default off (no file), opt-in true (file written),
no-op method on default agents, logs_dir retained unconditionally
- Update CONTRIBUTING.md and the bundled `hermes-agent` skill to
document the flag and its default
