The gateway's media delivery allowlist required files live inside
`~/.hermes/cache/{documents,images,...}`, which is the wrong shape for
real agent usage. Agents naturally produce artifacts via terminal tools
(`pandoc -o /tmp/report.pdf`, `matplotlib savefig`, etc.) or
write_file into project directories — these never land under the cache.
Result: users got a raw file path in chat instead of an attachment.
This is doubly bad in deployment shapes where the cache directories
aren't writable by the agent at all: Hermes running in Docker with a
read-only mount, or with a Docker/Modal/SSH terminal backend whose
filesystem isn't the gateway host's filesystem.
Layered trust model:
1. Cache-dir allowlist (unchanged) — Hermes-managed roots always trusted.
2. Operator allowlist — `HERMES_MEDIA_ALLOW_DIRS` env var, now also
surfaced as `gateway.media_delivery_allow_dirs` in config.yaml.
3. Recency-based trust (new, default on) — files whose mtime is within
`gateway.trust_recent_files_seconds` (default 600s) of "now" are
trusted even outside the cache/operator allowlist. Old host files
(`/etc/passwd`, `~/.bashrc`, `~/.ssh/id_rsa`) have mtimes measured
in days/months, well outside the window — prompt-injection paths
pointing at pre-existing files are still rejected.
4. Hard denylist — `/etc`, `/proc`, `/sys`, `/dev`, `/root`, `/boot`,
`/var/{log,lib,run}`, plus `$HOME/.{ssh,aws,gnupg,kube,docker,config,
azure,gcloud}` and `Library/Keychains`. Denylist blocks delivery
even when recency would trust the file, in case an attacker
somehow refreshes a sensitive file's mtime.
Operators who want strict-allowlist behavior set
`gateway.trust_recent_files: false` and the system reverts to
pre-existing behavior.
Tests: 6 new cases in test_platform_base.py cover the recency window,
disabled mode, system-path denylist, and the motivating PDF-in-project
scenario. 3 existing tests (test_platform_base, test_tts_media_routing,
test_send_message_tool) that exercised the strict-allowlist path are
updated to disable recency trust explicitly.
E2E validation: real `validate_media_delivery_path()` accepts fresh
PDFs in /tmp and project dirs, rejects /etc/passwd, ~/.ssh/id_rsa, and
files older than the window; config.yaml `gateway.*` keys bridge
correctly to the env vars the validator reads.
When the user runs OAuth on a remote/SSH machine without a port forward,
the OAuth provider redirects to http://127.0.0.1:<port>/callback which
only the listener on the remote machine can receive — the user's browser
on another box just shows a connection error.
_wait_for_callback() now races the HTTP listener against a stdin reader
on interactive TTYs. The user can copy the URL from the browser's address
bar after authorization (which contains code=...&state=...) and paste it
back at the prompt. Whichever fills the result dict first wins; the HTTP
listener remains the primary path for local sessions and SSH tunnels.
Accepts any of:
- Full local redirect URL: http://127.0.0.1:N/callback?code=...&state=...
- Provider URL after redirect: https://mcp.linear.app/callback?code=...&state=...
- Just the query string: ?code=...&state=... or code=...&state=...
The paste thread only spawns when _is_interactive() is true, preserving
the existing 'no input() in headless runs' invariant — verified by
TestWaitForCallbackPasteIntegration.test_paste_prompt_NOT_shown_when_noninteractive.
The SSH-session hint in _redirect_handler is updated to surface the paste
option as the primary remedy, with ssh -L tunneling as the alternative.
_update_via_zip downloads a source ZIP from GitHub and calls
zipfile.ZipFile.extractall. The existing zip-slip path guard validates
each member's path stays under tmp_dir, but does not check member type
— so a ZIP containing a symlink member would still be materialized by
extractall, and a symlink target could point outside the extracted
tree (or to a sensitive system path).
This isn't a high-likelihood threat for hermes-agent's actual GitHub
source ZIPs (we don't ship symlinks), but the extractall path runs as
the user's account and a compromised mirror could plant arbitrary files
via the symlink → target → write chain.
Reject any member whose Unix mode bits (upper 16 bits of external_attr)
are S_IFLNK before extractall. Hermes source ZIPs contain only regular
files and directories; a symlink member is unambiguously suspicious.
Regression tests cover: symlink member rejection (raises ValueError,
caught by the outer try/except as a clean SystemExit, no extraction),
and the happy-path verification that a normal ZIP doesn't trigger the
symlink reject message.

text_to_speech_tool accepts an explicit output_path. Without a traversal
guard, a path containing '..' components (whether prompt-injection-
controlled, from a confused skill, or just a buggy caller) could escape
its declared base and write the audio to a system location — e.g.
`output_path='audio/../../etc/cron.d/x'` lands the file outside the
intended audio cache.
Reject '..' components in the user-supplied path. Explicit absolute
paths are unchanged (the agent legitimately writes audio wherever the
user/caller asks); only traversal-style escapes are blocked. The
terminal tool can still write anywhere with approval — this just keeps
the unattended TTS surface from materializing files via traversal.
Regression tests cover: '..' in the middle (audio/../../etc/...),
bare '..' prefix, and the negative cases (absolute paths + relative
paths without '..' both pass through unchanged).
Salvaged from PR #6693 by @aaronlab. The original PR confined output to
DEFAULT_OUTPUT_DIR-or-cwd, which broke 9 existing tests that legitimately
write to tmp_path locations. The traversal-only check covers the actual
threat (path-escape via '..' from prompt injection) without restricting
where users can choose to write their audio.
The remaining pieces of #6693 (skill_commands rglob symlink rejection,
delegate_tool batch prefix display) are dropped:
- skill_commands rglob: breaks the documented design supporting
~/.hermes/skills/<name> as a symlink to a checked-out skill elsewhere
(see comment at agent/skill_commands.py:73-75)
- delegate_tool batch prefix: pure UX, doesn't belong in a security PR

* fix(streaming): route mid-tool-call partial-stream-stub through length continuation (#31998)
When a stream stalls mid-tool-call (e.g. a large write_file), the
partial-stream-stub recovery used finish_reason='stop' which caused the
conversation loop to treat the turn as complete, returning only the
warning text. When users said 'continue', the model retried the same
large tool call, hit the same stale timeout, and looped indefinitely.
Changes:
- chat_completion_helpers.py: change _stub_finish_reason from 'stop' to
'length' for mid-tool-call partials. The stub still has tool_calls=None
so no tool auto-executes — the model gets a fresh API call through the
existing length-continuation machinery (bounded to 3 retries).
Also attach _dropped_tool_names to the stub for downstream use.
- conversation_loop.py: add a third continuation prompt branch for
partial-stream-stubs with dropped tool calls. Instead of the generic
'continue where you left off' (which would retry the same large call),
tell the model to break the output into smaller tool calls (~8K
tokens each) to avoid stream timeouts.
- test_partial_stream_finish_reason.py: update existing test from
finish_reason='stop' to 'length', add _dropped_tool_names assertion,
add new test_dropped_tool_call_uses_chunking_prompt for the 3-way
prompt branching.
Safety: tool_calls=None is preserved on the stub, so the conversation
loop enters the text-continuation branch (line 1513), NOT the tool-call
execution branch (line 3246). No tool auto-executes. The model simply
gets another API call with targeted guidance.
* refactor: extract constants and continuation prompt helper
- Move magic strings to hermes_constants.py (PARTIAL_STREAM_STUB_ID,
FINISH_REASON_LENGTH)
- Extract _get_continuation_prompt() in conversation_loop.py — DRYs the
3-way prompt branching and lets tests import the real function
- Trim verbose inline comments in chat_completion_helpers.py
- Tests import constants + helper instead of duplicating logic

The test set HERMES_YOLO_MODE=1 via monkeypatch.setenv, expecting
check_dangerous_command() to honor yolo and bypass cron_mode=deny. But
tools.approval._YOLO_MODE_FROZEN is intentionally frozen at module
import time (security: prevents prompt-injection runtime escalation).
When CI imports the module BEFORE the test sets the env, the frozen
value stays False and the yolo bypass never activates.
Local runs missed this because the conftest leaked a non-empty
HERMES_YOLO_MODE into the import-time env. CI's clean-env path exposed
the bug deterministically on test (3) / test (4) shards.
Fix: patch the module attribute directly via mock.patch.object so the
test simulates process-startup-with-yolo regardless of import order.
The behavior under test (yolo bypasses cron_mode=deny for non-hardline
commands) is unchanged; the security invariant (_YOLO_MODE_FROZEN can't
be set at runtime by skills) is preserved.
Reproduced locally with: env -i HOME=$HOME PATH=$PATH python3 -m pytest

Without the fix: 1 failed, 23 passed. With the fix: 24 passed.
* fix(transcription): reject symlinked audio inputs
Validation runs before provider selection, so rejecting symbolic-link paths there prevents supported-extension links from being treated as normal audio files. Use os.path.islink to avoid perturbing the existing Path.stat error path and to reject links before resolving targets.
Constraint: Keep validation platform-safe and avoid requiring symlink support where unavailable.
Rejected: Use Path.is_symlink | it consumes pathlib stat calls and broke the existing stat error regression.
Confidence: high

Not-tested: Full tests/tools/test_transcription_tools.py under .[dev] only; existing faster_whisper optional dependency tests fail with ModuleNotFoundError.
* Keep transcription tests independent of optional whisper install
The transcription suite mocks faster-whisper directly, so a minimal test stub keeps the branch verifiable in environments where the optional package is not installed. This preserves the existing mock-based coverage without adding a dependency.
Constraint: faster-whisper is an optional local STT dependency and is absent from the current validation environment
Rejected: Install faster-whisper just for branch validation | would add heavyweight environment coupling outside the patch scope
Confidence: high

* fix: reject read_file symlinks to blocking devices
The read_file guard already refused direct device paths such as /dev/zero, but a workspace symlink resolving to one of those devices could still reach the shell-backed read path and hang on wc/head/sed.

* Keep file guard tests off sensitive macOS temp paths
The branch now inherits a sensitive-path write guard from upstream main. On macOS, tempfile.mkdtemp() resolves under /private/var/folders, so the new write-path guard fired before the file read dedup assertions could exercise their intended behavior. The tests now create their scratch files inside the worktree temp checkout, outside those system-sensitive prefixes, without changing production behavior.
Constraint: Rebased branch must pass the expanded file read guard suite on macOS.
Rejected: Loosen the production sensitive-path prefix list | broader behavior change unrelated to this PR.

The read_file tool and terminal cat can access /proc/self/environ to
recover all process env vars including secrets stripped by the subprocess
blocklist. Output redaction partially mitigates (catches known-format
tokens) but misses custom/proprietary key formats, especially when
values are printed without their key names.
Add /proc/*/environ, /proc/*/cmdline, and /proc/*/maps to the blocked
device paths in _is_blocked_device():
- /proc/*/environ: leaks full process env (API keys, tokens)
- /proc/*/cmdline: leaks command-line args (may contain passwords)
- /proc/*/maps: leaks memory layout (ASLR bypass for exploitation)
Legitimate /proc reads (cpuinfo, meminfo, uptime, version) remain
accessible — the check only blocks per-pid pseudo-files with known
sensitive suffixes.
Complements PR #4432 (PID namespace isolation for child processes)
which prevents children from reading the parent's /proc, but does not
prevent the parent process itself from being read via file tools.
Partially addresses #4427

When the terminal drops the ESC[201~ end mark during a bracketed paste
(terminal race, torn write, SSH glitch, macOS sleep/wake), prompt_toolkit's
Vt100Parser keeps buffering all later input in _paste_buffer forever. From
the user's perspective, the CLI appears frozen — the only recovery was
closing the tab/session.
This patch monkey-patches Vt100Parser.feed() so that bracketed-paste mode
flushes buffered content as a normal BracketedPaste event after 2 seconds
without an end marker, then restores normal parsing.
Includes 8 regression tests covering normal paste, timeout recovery,
torn end marks, and edge cases.
Surgical reapply of PR #27518. Original branch was many months stale
(1193 files / 172k LOC of unrelated reverts); the substantive ~77 LOC
patch in cli.py plus the new 157-line test file were reapplied onto
current main with the contributor's authorship preserved via --author.
A Ctrl+C during a slow slash command (e.g. /skills browse on a large
skill tree, /sessions list against a multi-GB SQLite DB) used to unwind
past self.process_command() to the outer prompt_toolkit event loop,
which killed the entire session — losing all conversation state.
Fix: wrap the slash-command dispatch in try/except KeyboardInterrupt
so Ctrl+C aborts the command but the prompt loop continues. Other
exceptions still propagate so real bugs aren't silently swallowed.
Surgical reapply of PR #5189. Original branch was many months stale
(3764 files / 1M+ LOC of unrelated reverts); the substantive ~6 LOC
change in cli.py was reapplied by hand onto current main with the
contributor's authorship preserved via --author.
On Windows (PowerShell/Windows Terminal), the queue-based modal used for
destructive slash command confirmations deadlocks because prompt_toolkit's
input channel becomes unresponsive when entered from the process_loop daemon
thread. Keystrokes never reach the key bindings, so response_queue.get()
blocks until the 120-second timeout expires.
Fix: fall back to _prompt_text_input (stdin-based) when:
1. sys.platform == 'win32' — Windows console doesn't support the modal reliably
2. Called from non-main thread — key bindings can't fire from daemon threads
3. self._app is not set — existing behavior for tests/non-interactive
This mirrors the thread-aware guard from _prompt_text_input (PR #23454).
9 new regression tests covering Windows detection, non-main thread fallback,
macOS/Linux modal preservation, and integration with _confirm_destructive_slash.

The ChatGPT Codex backend (chatgpt.com/backend-api/codex) has historically
silently dropped certain model requests: the connection is accepted but no
stream events are emitted and no error is raised. PR #31967 lowered the
implicit stale-call default from 300s to 90s so fallbacks kick in faster,
but users still see an opaque "No response from provider for 90s
(non-streaming, ...)" message that gives no path forward.
This patch adds a narrow heuristic — gpt-5.5 family on the Codex backend
via codex_responses api_mode — that substitutes the generic timeout
message with actionable text naming the gpt-5.4-codex workaround and
pointing at #21444 for symptom history.
Changes:
- run_agent.py — new ``AIAgent._codex_silent_hang_hint(model=...)`` method.
Returns ``None`` for any request that does not match all three guards
(codex_responses api_mode, openai-codex provider or chatgpt.com Codex
base URL, gpt-5.5-family model name with word-boundary regex anchoring
to avoid false-positives on e.g. ``gpt-5.50``).
- agent/chat_completion_helpers.py — the non-stream stale-call site
consults the hint via ``getattr(...)`` so the call site stays robust
if the helper is ever removed or stubbed in tests. Hint is appended to
both the ``_emit_status`` warning and the ``TimeoutError`` message so
the user sees it in their terminal AND it lands in any retry-loop
diagnostics.
- tests/run_agent/test_codex_silent_hang_hint.py — 10 regression tests
covering positive cases (bare gpt-5.5, vendor-prefixed openai/gpt-5.5,
gpt-5.5-codex SKU, model=None fallback to self.model) and negative
cases (gpt-5.4-codex workaround, gpt-5.50 false-positive guard,
non-codex api_mode, non-codex provider, empty/None model, unrelated
models on Codex).
Does NOT fix the backend-side issue (that's an upstream OpenAI/ChatGPT
problem we cannot patch from here). Only converts an opaque timeout into
text that names the workaround so users do not have to dig through logs
or wait for a forum post to learn what to do.
Closes#22046
get_read_block_error() only blocked internal Hermes cache files but
allowed reading project-local secret-bearing environment files (.env,
.env.production, .env.local, etc.) through both read_file and ACP
fs/read_text_file paths.
Add a basename deny set for common secret-bearing .env variants.
.env.example remains readable as documentation.
Fixes#20734
.env holds API keys and secrets. Multiple creation sites used `cp` /
`touch` / `shutil.copy2` which obey the process umask — commonly
0o022, leaving the file at 0o644 (world-readable). Apply chmod 0o600
explicitly at every site that creates or copies .env.
Sites covered:
- docker/stage2-hook.sh: after the seed_one '.env' call, applied
unconditionally (not just on first-seed) so a host-mounted .env with
loose perms gets tightened on every container restart
- hermes_cli/doctor.py: 'hermes doctor --fix' touches an empty .env
when missing
- hermes_cli/profiles.py: 'hermes profile create --clone' copies .env
from the source profile; shutil.copy2 preserves source mode, so a
source .env at 0o644 was being cloned into 0o644
- setup-hermes.sh: in-tree setup script's cp .env.example .env path,
plus the already-exists branch (mirror of install.sh which already
chmods 600 unconditionally on line 1442)
scripts/install.sh was NOT changed — it already chmod 600's the .env
unconditionally after the create/already-exists branches (line 1442).
Salvaged from PR #25726 by @dusterbloom. The docker/entrypoint.sh
portion of the original PR was dropped because main switched to an
s6-overlay shim — the .env creation logic moved to stage2-hook.sh,
which is where the chmod now lives.
Closes#25497 (subset — install.sh + setup-hermes.sh) and #8448
(subset — install.sh only) as superseded.

register_env_passthrough() (the skill-declared path) filters out names in
_HERMES_PROVIDER_ENV_BLOCKLIST and logs a warning citing GHSA-rhgp-j443-p4rf.
_load_config_passthrough() (the config.yaml path) did not. Both feed the
same is_env_passthrough() allowlist that local.py and code_execution_tool.py
consult before stripping a variable from the child env.
A skill that wanted to leak ANTHROPIC_API_KEY or OPENAI_API_KEY into
execute_code could no longer self-register the name (the GHSA fix
blocks it), but the same outcome was still reachable by asking the
operator to add the name to terminal.env_passthrough in config.yaml,
or by any in-process actor with write access to ~/.hermes/config.yaml.
Apply the same _is_hermes_provider_credential filter inside
_load_config_passthrough, mirroring the skill-path warning so operators
see the same explanation. Non-Hermes API keys (TENOR_API_KEY,
NOTION_TOKEN, etc.) are unaffected since they are not in the blocklist.
* perf(bitwarden): persist secret-fetch cache across CLI invocations
Every `hermes` invocation paid a ~380ms tax for `bws secret list` to
Bitwarden Secrets Manager because the existing cache was in-process only.
Back-to-back `hermes chat -q`, gateway-spawned agents, and cron-launched
runs all re-fetched.
Adds a disk-persisted L2 cache at `<hermes_home>/cache/bws_cache.json`
(mode 0600, never contains the access token — only the SHA-256
fingerprint prefix). Same TTL as the in-process cache. Read on miss,
write on bws success, ignored on key mismatch / corruption / expiry.
Measured on a startup profile:
load_hermes_dotenv() cold: 372ms → warm (disk cache hit): 20ms
End-to-end `hermes --version` cold→warm: 666ms → ~295ms.
In a hermes-vs-codex benchmark across 11 single- and multi-turn tasks
(framework overhead = wall − llm − tool_exec, median over 3 trials):
cohort before after saved
single-turn (median) 2.96s 2.31s -0.65s
multi-turn (5-turn) 9.40s 8.95s -0.45s (≈0.3s/turn)
Hermes now wins head-to-head on 6/11 tasks vs codex (was 4/11 before).
The remaining ~0.6s single-turn delta is mostly Python's own import
cost in hermes_cli.main, which is a separate optimization.
* perf(cli): lazy-load model catalog + dedupe config.yaml reads at startup
Two import-time wins on top of the bws disk-cache fix:
1. Lazy-load `hermes_cli.models._PROVIDER_MODELS` via PEP 562
module-level `__getattr__`. The catalog is ~55ms of work that was
eagerly imported on every CLI invocation (line 4557 `if not
_is_termux_startup_environment(): from hermes_cli.models import
_PROVIDER_MODELS`). Audit showed every internal call site already
does its own function-local import; only test code reads
`hermes_cli.main._PROVIDER_MODELS` as a module attribute, and
__getattr__ keeps that working transparently. First access triggers
the import once and caches the result on the module via
`globals()[name] = ...`, so subsequent reads are dict lookups.
2. Dedupe the double config.yaml read in the top-of-module bootstrap.
Previously: one raw yaml.safe_load for the `security.redact_secrets`
bridge, then a separate full `load_config()` (with deep-merge) for
`network.force_ipv4`. Both keys come from the same file. Merged
into one raw yaml load.
Combined with the bws cache fix in the previous commit:
hermes --version wall time:
original (cold): 666 ms
after bws fix (warm): 295 ms
after lazy-load + dedupe: 228 ms (-67 ms additional, -66% from original)
Tests:
- tests/hermes_cli/test_api_key_providers.py: 173/173 pass
(lazy __getattr__ correctly handles
`from hermes_cli.main import _PROVIDER_MODELS`)
- tests/test_ipv4_preference.py + tests/hermes_cli/test_redact_config_bridge.py +
tests/agent/test_redact.py: 93/93 pass (dedupe preserves both bridges)
- tests/test_bitwarden_secrets.py + env_loader tests: 49/49 pass
V4A patch '*** Update File:', '*** Add File:', '*** Delete File:' headers
come from patch CONTENT, not the explicit `path=` argument. That makes
them attacker-influenceable through skill content, web extract output,
prompt injection, and other surfaces the agent processes. Headers like
'*** Update File: ../../../etc/shadow' would resolve relative to the
agent's cwd; in deployment configurations where that cwd is deep enough
to land outside Hermes' protected paths, the write could land somewhere
the agent operator did not intend.
Reject any V4A header containing a '..' path component before applying
the patch. The explicit `path=` argument on patch_tool is UNCHANGED —
the agent legitimately uses '..' there (e.g. `patch path='../other_module/x.py'`
from a worktree dir is normal cross-module editing).
Regression tests: V4A Update header with traversal rejected, V4A Add
header with traversal rejected, patch_v4a never invoked when rejection
fires.
Salvaged from PR #29395 by @waefrebeorn. The original PR added
has_traversal_component as a blanket reject on read_file_tool,
write_file_tool, patch_tool's explicit path, and search_tool — that
would break legitimate agent operation where '..' is normal. Also
dropped the over-eager skills_guard pattern additions
(pickle.loads/marshal.loads/ctypes.CDLL/importlib at high/critical
severity would false-positive on legit data-science and FFI skills).

hidden_div
- Add exfiltration patterns: send_to_url, context_exfil
- Add persistence patterns: agent_config_mod, hermes_config_mod
(both require modification-verb prefix to avoid false positives on
mere mentions of config filenames)
- Add hardcoded secret detection pattern
- Add role_hijack precision fix: require article after "now" to avoid
blocking "you are now ready/connected/set up" etc.
- Expand invisible unicode set with directional isolates (U+2066-2069)
and invisible math operators (U+2062-2064)
Test coverage expanded from ~8 to ~30 scan tests including dedicated
false-positive regression tests for all precision-sensitive patterns.
Known limitations (deferred to follow-up PRs):
- prompt_builder.py and cronjob_tools.py still use older pattern sets
- No semantic/LLM-based scanning (regex-only approach)
- No cross-entry or cross-store analysis
show_snapshot.py unpickled a user-supplied path unconditionally. pickle.loads
is equivalent to arbitrary code execution, so a snapshot from an untrusted
source = RCE. Require an explicit --i-trust-this-file acknowledgement before
calling pickle.loads, and emit a stderr warning when proceeding.

Codex / Responses-API requests had three latent timeout bugs that combined
into the long silent hangs reported on #21444:
1. The non-stream stale-call detector estimated context tokens from
``api_kwargs["messages"]`` only. Codex / Responses-API payloads carry
their conversational load in ``input`` (with ``instructions`` and
``tools``), so every Codex turn logged ``context=~0 tokens`` and the
detector never applied its >50k / >100k tier bumps.
2. ``providers.<id>.request_timeout_seconds`` was silently dropped on the
main Codex path. The chat_completions path and the auxiliary Codex
adapter both forwarded it; the main path skipped it through three
places (``build_api_kwargs``, ``ResponsesApiTransport.build_kwargs``,
``_preflight_codex_api_kwargs``).
3. The streaming stale detector had the same payload-shape bug for
``codex_responses`` requests, which route through the non-streaming
detector (it's the path that emits the user-facing
"No response from provider for 300s (non-streaming, ...)" warning that
reporters keep pasting).
This commit:
- Adds ``estimate_request_context_tokens`` in ``chat_completion_helpers``,
used by both the non-stream and stream detectors. Handles ``messages``
(Chat Completions), ``input + instructions + tools`` (Responses API),
bare lists, and an unknown-dict fallback.
- Forwards ``timeout`` through ``ResponsesApiTransport.build_kwargs``
and ``_preflight_codex_api_kwargs`` (with guards against
zero/negative/inf/bool values), and wires
``_resolved_api_call_timeout()`` into the Codex branch of
``build_api_kwargs``.
- Lowers the implicit non-stream stale defaults so fallback providers
kick in faster when upstream stalls:
* base 300s -> 90s
* >50k 450s -> 150s
* >100k 600s -> 240s
These only apply when the user has *not* set
``providers.<id>.stale_timeout_seconds`` or
``HERMES_API_CALL_STALE_TIMEOUT``. Explicit config still wins.
- Adds regression tests for the estimator shapes, the new defaults, the
context-tier scaling, transport timeout pass-through, and preflight
timeout pass-through / rejection of invalid values.

Translates the full English docs corpus (335 files) into Simplified
Chinese under website/i18n/zh-Hans/. Combined with PR #31895 (cross-
locale link fix), the 简体中文 locale toggle now serves a complete
Chinese site with working cross-page navigation.
Pipeline:
- Claude Sonnet 4.6 via OpenRouter, 8-way concurrent
- Preserves frontmatter keys, code blocks, MDX/JSX, link URLs, brand
names, and technical jargon (prompt/token/hook/MCP/ACP/etc.)
- Translates only frontmatter title/description and prose
- Two largest files (configuration.md 93KB, research-paper-writing.md
107KB) retried with 64K max_tokens after initial fence-drift
- 3 manual post-fixes for MDX edge cases the model didn't escape:
< in optional-skills-catalog table, double-quotes in an alt= tag,
and a bare URL adjacent to a full-width period
Cost: ~$30 total (Sonnet 4.6 input $3/M + output $15/M).
Verified `npm run build` succeeds for both en and zh-Hans locales,
no double-prefixed /docs/zh-Hans/docs/ URLs in rendered output,
all in-page navigation resolves correctly.
Translations are machine-generated and may need human review on
specific pages — but they're an enormous improvement over the
previous state (3 zh-Hans pages out of 335).
When 'hermes chat --quiet --resume <id> -q "..."' is used, three status
messages were written to stdout via ChatConsole / _cprint:
- '↻ Resumed session <id> (N user messages, M total messages)'
- 'Session <id> found but has no messages. Starting fresh.'
- 'Session not found: <id>' / usage hint
This polluted the machine-readable stdout that automation wrappers capture
with $(...), making it impossible to cleanly separate the agent's answer
from the resume banner.
Fix: detect quiet mode via tool_progress_mode == 'off' and route the three
resume status messages to stderr (as plain text, matching the existing
stderr convention for session_id). Interactive mode is unchanged — it
still uses the Rich-rendered path through ChatConsole.

Follow-up to @someaka's fix.
Polish:
- Drop the redundant `_preflight_tokens >= threshold_tokens` clause.
`should_compress(tokens)` already short-circuits when tokens < threshold,
so the explicit comparison was dead code on the True branch.
Tests:
- Preflight: pin that should_compress() is called (anti-thrash has a vote).
Mocks should_compress to return False even with tokens past the raw
threshold and asserts no compression runs — exact bug shape from #29335.
- Gateway: AST scan of gateway/run.py asserts every
`session_entry.session_id = ...` assignment is followed by a
`session_store._save()` call within the same block. Three sites mutate
the session_id after compression; all three must persist or the next
turn loads the pre-compression transcript and re-loops. Empirically
verified the test catches the bug (drops the new _save() line → red).
AUTHOR_MAP:
- Map ed@bebop.crew -> someaka so the salvaged commit resolves to
@someaka in release notes.
Three compounding root causes:
A) run_conversation() result dict missing session_id — gateway's
dead-code guard at gateway/run.py:8700 never triggers
B) preflight compression bypasses should_compress() anti-thrashing —
re-triggers every turn when tool schemas dominate token budget
C) gateway updates session_entry.session_id in memory but doesn't
persist via session_store._save()
Fixes: #29335
Session IDs are profile-constrained, so the resume hint needs to
include the active profile for multi-profile users. Without this,
copying the hint from a non-default profile fails to resume the
correct session.
Before: hermes --resume 20260414_063228_c1240e
After: hermes --resume 20260414_063228_c1240e -p dev
Also includes -p on the resume-by-title hint. Skipped for
'default' and 'custom' profiles (no -p needed).

Mirror of the TTS command-provider registry (PR #17843) for STT. Lets any
shell-driven ASR engine — Doubao ASR, NVIDIA Parakeet, whisper.cpp builds,
SenseVoice, curl pipelines — become an STT backend with zero Python.
Complements the legacy HERMES_LOCAL_STT_COMMAND escape hatch (preserved
untouched via the built-in local_command path) and the
register_transcription_provider() Python plugin hook also shipped in this
PR.
Resolution order (mirrors TTS exactly):
1. Built-in (local, local_command, groq, openai, mistral, xai)
→ native handler. Always wins.
2. stt.providers.<name>: type: command → command-provider runner.
3. Plugin-registered TranscriptionProvider → plugin dispatch.
4. No match → 'No STT provider available'.

- tools/transcription_tools.py: BUILTIN_STT_PROVIDERS frozenset retained;
added _resolve_command_stt_provider_config, _transcribe_command_stt,
and local helpers for template rendering, shell-quote context, and
process-tree termination. Helpers are documented as mirrors of their
tts_tool.py counterparts (kept local to avoid cross-tool private
import). Wire-in is one insertion point in transcribe_audio() after
the xai elif and before the plugin dispatcher. Plugin dispatcher
additionally defensively short-circuits when a same-name command
config exists (command-wins-over-plugin invariant).
- tests/tools/test_transcription_command_providers.py: 50 new tests
covering resolution (builtin precedence, type/command gating,
case-insensitive lookup, legacy stt.<name> back-compat), helpers
(timeout fallback, format validation, iter, has-any), template
rendering (shell-quote contexts, doubled-brace preservation),
end-to-end via _transcribe_command_stt (output_path read, stdout
fallback, timeout, nonzero exit envelope, model override,
language precedence), and dispatcher integration via the real
transcribe_audio() including command-wins-over-plugin and
builtin-shadow-rejection.
- tests/plugins/transcription/check_parity_vs_main.py: extended from
10 to 13 scenarios. New cases: command-provider-installed,
command-vs-plugin-same-name (verifies command wins precedence),
explicit-openai-with-command-shadow (verifies built-in wins).
Adds command_provider dispatch_kind detection via transcript prefix
(CMD: vs PLUGIN:) so command-provider scenarios can be distinguished
from plugin scenarios even when sharing a provider name.
- website/docs/user-guide/features/tts.md: new 'STT custom command
providers' section symmetric to the TTS section — example config,
placeholder grammar table (input_path / output_path / output_dir /
format / language / model), transcript-read-back semantics (file
first, then stdout fallback), optional keys table, behavior notes,
security note. Updated 'Python plugin providers (STT)' to include
the new 'When to pick which (STT)' decision table and updated
resolution-order section (now 4 layers instead of 3).
Verification
------------
189/189 STT targeted tests + 50/50 new command-provider tests pass.
Combined sweep: tests/tools/ 5576/5576, tests/agent/ + tests/hermes_cli/
8623/8623 — zero regressions across 14,199 tests.
Parity harness: 13 scenarios, 9 OK + 4 expected diffs
(no_provider_error → plugin, plugin_unavailable, command_provider × 2).
E2E live-verified in an isolated HERMES_HOME with a real .wav file:
command: → dispatched to stt.providers.my-fake-cli
plugin: → dispatched to registered TranscriptionProvider
command-wins-over-plugin: → command provider beats same-name plugin
builtin-wins-over-command: → built-in OpenAI handler fires;
stt.providers.openai: type: command
does NOT hijack it.
Add an opt-in Python plugin surface for speech-to-text backends,
mirroring the TTS hook pattern. New backends (OpenRouter, SenseAudio,
Gemini-STT, custom proprietary engines) can be implemented as plugins
without modifying tools/transcription_tools.py.
Built-ins always win
--------------------
The 6 built-in STT providers (local/faster-whisper, local_command,
groq, openai, mistral, xai) keep their native handlers. Plugins
attempting to register under a built-in name are rejected at
registration time with a warning and re-checked defensively at
dispatch.
Resolution order
----------------
1. stt.provider matches a built-in → built-in dispatch (unchanged)
2. stt.provider matches a registered plugin →
a. if plugin.is_available() returns False → unavailability envelope
identifying the plugin (not the generic "No STT provider"
message — the user explicitly opted into this plugin)
b. otherwise plugin.transcribe() with model + language forwarded
from stt.<provider>.{model,language} config
3. No match → legacy "No STT provider available" error (unchanged)
Per-provider config namespace
-----------------------------
Plugins read their config from stt.<provider> in config.yaml, mirroring
how built-ins read stt.openai.model / stt.mistral.model. The dispatcher
forwards `model` and `language` from this section. Caller's explicit
`model=` argument overrides the config-set model.

Issue follow-up to #30398.
- CLI: bracketed/quoted target resolves; mismatched single bracket passes through unchanged.
- Gateway: bracketed session ID resolves; bare untitled session ID resolves via get_session() fallback.
The /resume usage hint shows '<session_id_or_title>' which a few users have
typed verbatim, including the angle brackets. Strip outer <>, [], "", and ''
from the argument before lookup so '/resume <abc123>' works the same as
'/resume abc123'. Mirrors the new bracket-stripping in the CLI handler.
Also let the gateway resolve a bare session ID. Previously the gateway only
called resolve_session_by_title, so '/resume <session_id>' always returned
'Session not found' even for valid IDs. Try get_session() first, fall back
to title resolution second.
Surgical reapply of PR #10215 (branch was based on a many-months-old main
and reverted ~3100 unrelated files; original commit by claw@openclaw.ai
preserved via --author).
PR #31416 (avoid persisting borrowed credential secrets) added
sanitize_borrowed_credential_payload, which strips access_token from
any auth.json pool entry whose (provider, source) isn't in the
_PERSISTABLE_PROVIDER_SOURCES allowlist.
(copilot, gh_cli) is borrowed (not in the allowlist), so the test
fixture's pre-seeded access_token now gets stripped at load_pool()
time, leaving the pool empty. resolve_target('1') then fails with
'No credential #1. Provider: copilot.'
Fix: align the test with the new contract. At runtime, copilot tokens
are hydrated by resolve_copilot_token() — mock that path so the pool
gets an entry the test can remove. The behavior under test
(suppression of gh_cli + env variants on remove) is unchanged.
CI repro on origin/main HEAD; reproduced locally with stock checkout.
Extend PR #31716 to plugin setup paths that were also using bare
getpass.getpass(): hindsight (4 sites), honcho, simplex, line. Same
mechanical swap onto hermes_cli.secret_prompt.masked_secret_prompt.
