Cron now resolves its toolset from the same per-platform config the
gateway uses — `_get_platform_tools(cfg, 'cron')` — instead of blindly
loading every default toolset. Existing cron jobs without a per-job
override automatically lose `moa`, `homeassistant`, and `rl` (the
`_DEFAULT_OFF_TOOLSETS` set), which stops the "surprise $4.63
mixture_of_agents run" class of bug (Norbert, Discord).
Precedence inside `run_job`:
1. per-job `enabled_toolsets` (PR #14767 / #6130) — wins if set
2. `_get_platform_tools(cfg, 'cron')` — new, the blanket gate
3. `None` fallback (legacy) — only on resolver exception
Changes:
- hermes_cli/platforms.py: register 'cron' with default_toolset
'hermes-cron'
- toolsets.py: add 'hermes-cron' toolset (mirrors 'hermes-cli';
`_get_platform_tools` then filters via `_DEFAULT_OFF_TOOLSETS`)
- cron/scheduler.py: add `_resolve_cron_enabled_toolsets(job, cfg)`,
call it at the `AIAgent(...)` kwargs site
- tests/cron/test_scheduler.py: replace the 'None when not set' test
(outdated contract) with an invariant ('moa not in default cron
toolset') + new per-job-wins precedence test
- tests/hermes_cli/test_tools_config.py: mark 'cron' as non-messaging
in the gateway-toolset-coverage test
Themes and plugins can now pull off arbitrary dashboard reskins (cockpit
HUD, retro terminal, etc.) without touching core code.
Themes gain four new fields:
- layoutVariant: standard | cockpit | tiled — shell layout selector
- assets: {bg, hero, logo, crest, sidebar, header, custom: {...}} —
artwork URLs exposed as --theme-asset-* CSS vars
- customCSS: raw CSS injected as a scoped <style> tag on theme apply
(32 KiB cap, cleaned up on theme switch)
- componentStyles: per-component CSS-var overrides (clipPath,
borderImage, background, boxShadow, ...) for card/header/sidebar/
backdrop/tab/progress/badge/footer/page
Plugin manifests gain three new fields:
- tab.override: replaces a built-in route instead of adding a tab
- tab.hidden: register component + slots without adding a nav entry
- slots: declares shell slots the plugin populates
10 named shell slots: backdrop, header-left/right/banner, sidebar,
pre-main, post-main, footer-left/right, overlay. Plugins register via
window.__HERMES_PLUGINS__.registerSlot(name, slot, Component). A
<PluginSlot> React helper is exported on the plugin SDK.
Ships a full demo at plugins/strike-freedom-cockpit/ — theme YAML +
slot-only plugin that reproduces a Gundam cockpit dashboard: MS-STATUS
sidebar with live telemetry, COMPASS crest in header, notched card
corners via componentStyles, scanline overlay via customCSS, gold/cyan
palette, Orbitron typography.
Validation:
- 15 new tests in test_web_server.py covering every extended field
- tests/hermes_cli/: 2615 passed (3 pre-existing unrelated failures)
- tsc -b --noEmit: clean
- vite build: 418 kB bundle, ~2 kB delta for slots/theme extensions

float(os.getenv(...)) at module level raises ValueError on any
non-numeric value, crashing the web server at import before it starts.
Wrap in try/except with a warning log and fallback to 3.0s.
cmd_update no longer SIGKILLs in-flight agent runs, and users get
'still working' status every 3 min instead of 10. Two long-standing
sources of '@user — agent gives up mid-task' reports on Telegram and
other gateways.
Drain-aware update:
- New helper hermes_cli.gateway._graceful_restart_via_sigusr1(pid,
drain_timeout) sends SIGUSR1 to the gateway and polls os.kill(pid,
0) until the process exits or the budget expires.
- cmd_update's systemd loop now reads MainPID via 'systemctl show
--property=MainPID --value' and tries the graceful path first. The
gateway's existing SIGUSR1 handler -> request_restart(via_service=
True) -> drain -> exit(75) is wired in gateway/run.py and is
respawned by systemd's Restart=on-failure (and the explicit
RestartForceExitStatus=75 on newer units).
- Falls back to 'systemctl restart' when MainPID is unknown, the
drain budget elapses, or the unit doesn't respawn after exit (older
units missing Restart=on-failure). Old install behavior preserved.
- Drain budget = max(restart_drain_timeout, 30s) + 15s margin so the
drain loop in run_agent + final exit have room before fallback
fires. Composes with #14728's tool-subprocess reaping.
Notification interval:
- agent.gateway_notify_interval default 600 -> 180.
- HERMES_AGENT_NOTIFY_INTERVAL env-var fallback in gateway/run.py
matched.
- 9-minute weak-model spinning runs now ping at 3 min and 6 min
instead of 27 seconds before completion, removing the 'is the bot
dead?' reflex that drives gateway-restart cycles.
Tests:
- Two new tests in tests/hermes_cli/test_update_gateway_restart.py:
one asserts SIGUSR1 is sent and 'systemctl restart' is NOT called
when MainPID is known and the helper succeeds; one asserts the
fallback fires when the helper returns False.
- E2E: spawned detached bash processes confirm the helper returns
True on SIGUSR1-handling exit (~0.5s) and False on SIGUSR1-ignoring
processes (timeout). Verified non-existent PID and pid=0 edge cases.
- 41/41 in test_update_gateway_restart.py (was 39, +2 new).
- 154/154 in shutdown-related suites including #14728's new tests.
Reported by @GeoffWellman and @ANT_1515 on X.
Closes#11616.
The agent's API retry loop hardcoded max_retries = 3, so users with
fallback providers on flaky primaries burned through ~3 × provider
timeout (e.g. 3 × 180s = 9 minutes) before their fallback chain got a
chance to kick in.
Expose a new config key:
agent:
api_max_retries: 3 # default unchanged
Set it to 1 for fast failover when you have fallback providers, or
raise it if you prefer longer tolerance on a single provider. Values
< 1 are clamped to 1 (single attempt, no retry); non-integer values
fall back to the default.
This wraps the Hermes-level retry loop only — the OpenAI SDK's own
low-level retries (max_retries=2 default) still run beneath this for
transient network errors.
Changes:
- hermes_cli/config.py: add agent.api_max_retries default 3 with comment.
- run_agent.py: read self._api_max_retries in AIAgent.__init__; replace
hardcoded max_retries = 3 in the retry loop with self._api_max_retries.
- cli-config.yaml.example: documented example entry.
- hermes_cli/tips.py: discoverable tip line.
- tests/run_agent/test_api_max_retries_config.py: 4 tests covering
default, override, clamp-to-one, and invalid-value fallback.
Closes#8202.
Root cause: stop() reclaimed tool-call bash/sleep children only at the
very end of the shutdown sequence — after a 60s drain, 5s interrupt
grace, and per-adapter disconnect. Under systemd (TimeoutStopSec bounded
by drain_timeout), that meant the cgroup SIGKILL escalation fired first,
and systemd reaped the bash/sleep children instead of us.
Fix:
- Extract tool-subprocess cleanup into a local helper
_kill_tool_subprocesses() in _stop_impl().
- Invoke it eagerly right after _interrupt_running_agents() on the
drain-timeout path, before adapter disconnect.
- Keep the existing catch-all call at the end for the graceful path
and defense in depth against mid-teardown respawns.
- Bump generated systemd unit TimeoutStopSec to drain_timeout + 30s
so cleanup + disconnect + DB close has headroom above the drain
budget, matching the 'subprocess timeout > TimeoutStopSec + margin'
rule from the skill.
Tests:
- New: test_gateway_stop_kills_tool_subprocesses_before_adapter_disconnect_on_timeout
asserts kill_all() runs before disconnect() when drain times out.
- New: test_gateway_stop_kills_tool_subprocesses_on_graceful_path
guards that the final catch-all still fires when drain succeeds
(regression guard against accidental removal during refactor).
- Updated: existing systemd unit generator tests expect TimeoutStopSec=90
(= 60s drain + 30s headroom) with explanatory comment.
A test in tests/agent/test_credential_pool.py
(test_try_refresh_current_updates_only_current_entry) monkeypatched
refresh_codex_oauth_pure() to return the literal fixture strings
'access-new'/'refresh-new', then executed the real production code path
in agent/credential_pool.py::try_refresh_current which calls
_sync_device_code_entry_to_auth_store → _save_provider_state → writes
to `providers.openai-codex.tokens`. That writer resolves the target via
get_hermes_home()/auth.json. If the test ran with HERMES_HOME unset (direct
pytest invocation, IDE runner bypassing conftest discovery, or any other
sandbox escape), it would overwrite the real user's auth store with the
fixture strings.
Observed in the wild: Teknium's ~/.hermes/auth.json providers.openai-codex.tokens
held 'access-new'/'refresh-new' for five days. His CLI kept working because
the credential_pool entries still held real JWTs, but `hermes model`'s live
discovery path (which reads via resolve_codex_runtime_credentials →
_read_codex_tokens → providers.tokens) was silently 401-ing.
Fixes:
- Delete test_try_refresh_current_updates_only_current_entry. It was the
only test that exercised a writer hitting providers.openai-codex.tokens
with literal stub tokens. The entry-level rotation behavior it asserted
is still covered by test_mark_exhausted_and_rotate_persists_status above.
- Add a seat belt in hermes_cli.auth._auth_file_path(): if PYTEST_CURRENT_TEST
is set AND the resolved path equals the real ~/.hermes/auth.json, raise
with a clear message. In production (no PYTEST_CURRENT_TEST), a single
dict lookup. Any future test that forgets to monkeypatch HERMES_HOME
fails loudly instead of corrupting the user's credentials.
Validation:
- production (no PYTEST_CURRENT_TEST): returns real path, unchanged behavior
- pytest + HERMES_HOME unset (points at real home): raises with message
- pytest + HERMES_HOME=/tmp/...: returns tmp path, tests pass normally
Dashboard themes now control typography and layout, not just colors.
Each built-in theme picks its own fonts, base size, radius, and density
so switching produces visible changes beyond hue.
Schema additions (per theme):
- typography — fontSans, fontMono, fontDisplay, fontUrl, baseSize,
lineHeight, letterSpacing. fontUrl is injected as <link> on switch
so Google/Bunny/self-hosted stylesheets all work.
- layout — radius (any CSS length) and density
(compact | comfortable | spacious, multiplies Tailwind spacing).
- colorOverrides (optional) — pin individual shadcn tokens that would
otherwise derive from the palette.
Built-in themes are now distinct beyond palette:
- default — system stack, 15px, 0.5rem radius, comfortable
- midnight — Inter + JetBrains Mono, 14px, 0.75rem, comfortable
- ember — Spectral (serif) + IBM Plex Mono, 15px, 0.25rem
- mono — IBM Plex Sans + Mono, 13px, 0 radius, compact
- cyberpunk— Share Tech Mono everywhere, 14px, 0 radius, compact
- rose — Fraunces (serif) + DM Mono, 16px, 1rem, spacious
Also fixes two bugs:
1. Custom user themes silently fell back to default. ThemeProvider
only applied BUILTIN_THEMES[name], so YAML files in
~/.hermes/dashboard-themes/ showed in the picker but did nothing.
Server now ships the full normalised definition; client applies it.
2. Docs documented a 21-token flat colors schema that never matched
the code (applyPalette reads a 3-layer palette). Rewrote the
Themes section against the actual shape.
Implementation:
- web/src/themes/types.ts: extend DashboardTheme with typography,
layout, colorOverrides; ThemeListEntry carries optional definition.
- web/src/themes/presets.ts: 6 built-ins with distinct typography+layout.
- web/src/themes/context.tsx: applyTheme() writes palette+typography+
layout+overrides as CSS vars, injects fontUrl stylesheet, fixes the
fallback-to-default bug via resolveTheme(name).
- web/src/index.css: html/body/code read the new theme-font vars;
--radius-sm/md/lg/xl derive from --theme-radius; --spacing scales
with --theme-spacing-mul so Tailwind utilities shift with density.
- hermes_cli/web_server.py: _normalise_theme_definition() parses loose
YAML (bare hex strings, partial blocks) into the canonical wire
shape; /api/dashboard/themes ships full definitions for user themes.
- tests/hermes_cli/test_web_server.py: 16 new tests covering the
normaliser and discovery (rejection cases, clamping, defaults).
- website/docs/user-guide/features/web-dashboard.md: rewrite Themes
section with real schema, per-model tables, full YAML example.
OpenAI launched GPT-5.5 on Codex today (Apr 23 2026). Adds it to the static
catalog and pipes the user's OAuth access token into the openai-codex path of
provider_model_ids() so /model mid-session and the gateway picker hit the
live ChatGPT codex/models endpoint — new models appear for each user
according to what ChatGPT actually lists for their account, without a Hermes
release.
Verified live: 'gpt-5.5' returns priority 0 (featured) from the endpoint,
400k context per OpenAI's launch article. 'hermes chat --provider
openai-codex --model gpt-5.5' completes end-to-end.
Changes:
- hermes_cli/codex_models.py: add gpt-5.5 to DEFAULT_CODEX_MODELS + forward-compat
- agent/model_metadata.py: 400k context length entry
- hermes_cli/models.py: resolve codex OAuth token before calling
get_codex_model_ids() in provider_model_ids('openai-codex')
Three bugs fixed in model alias resolution:
1. resolve_alias() returned the FIRST catalog match with no version
preference. '/model mimo' picked mimo-v2-omni (index 0 in dict)
instead of mimo-v2.5-pro. Now collects all prefix matches, sorts
by version descending with pro/max ranked above bare names, and
returns the highest.
2. models.dev registry missing newly added models (e.g. v2.5 for
native xiaomi). resolve_alias() now merges static _PROVIDER_MODELS
entries into the catalog so models resolve immediately without
waiting for models.dev to sync.
3. hermes model picker showed only models.dev results (3 xiaomi models),
hiding curated entries (5 total). The picker now merges curated
models into the models.dev list so all models appear.
Also fixes a trailing-dot float parsing edge case in _model_sort_key
where '5.4.' failed float() and multi-dot versions like '5.4.1'
weren't parsed correctly.
## Merged
Adds MiMo v2.5-pro and v2.5 support to Xiaomi native provider, OpenCode Go, and setup wizard.
### Changes
- Context lengths: added v2.5-pro (1M) and v2.5 (1M), corrected existing MiMo entries to exact values (262144)
- Provider lists: xiaomi, opencode-go, setup wizard
- Vision: upgraded from mimo-v2-omni to mimo-v2.5 (omnimodal)
- Config description updated for XIAOMI_API_KEY
- Tests updated for new vision model preference
### Verification
- 4322 tests passed, 0 new regressions
- Live API tested on Xiaomi portal: basic, reasoning, tool calling, multi-tool, file ops, system prompt, vision — all pass
- Self-review found and fixed 2 issues (redundant vision check, stale HuggingFace context length)
Replaces the blanket 'always allow' change from the previous commit with
an opt-in config flag so users who want belt-and-suspenders security can
still get the keyword scan on skill_manage output.
## Default behavior (flag off)
skill_manage(action='create'|'edit'|'patch') no longer runs the keyword
scanner. The agent can write skills that mention risky keywords in prose
(documenting what reviewers should watch for, describing cache-bust
semantics in a PR-review skill, referencing AGENTS.md, etc.) without
getting blocked.
Rationale: the agent can already execute the same code paths via
terminal() with no gate, so the scan adds friction without meaningful
security against a compromised or malicious agent.
## Opt-in behavior (flag on)
Set skills.guard_agent_created: true in config.yaml to get the original
behavior back. Scanner runs on every skill_manage write; dangerous
verdicts surface as a tool error the agent can react to (retry without
the flagged content).
## External hub installs unaffected
trusted/community sources (hermes skills install) always get scanned
regardless of this flag. The gate is specifically for skill_manage,
which only agents call.
## Changes
- hermes_cli/config.py: add skills.guard_agent_created: False to DEFAULT_CONFIG
- tools/skill_manager_tool.py: _guard_agent_created_enabled() reads the flag;
_security_scan_skill() short-circuits to None when the flag is off
- tools/skills_guard.py: restore INSTALL_POLICY['agent-created'] =
('allow', 'allow', 'ask') so the scan remains strict when it does run
- tests/tools/test_skills_guard.py: restore original ask/force tests
- tests/tools/test_skill_manager_tool.py: new TestSecurityScanGate class
covering both flag states + config error handling
## Validation
- tests/tools/test_skills_guard.py + test_skill_manager_tool.py: 115/115 pass
- E2E: flagged-keyword skill creates with default config, blocks with flag on
The environment-snapshot login shell was auto-sourcing only ~/.bashrc when
building the PATH snapshot. On Debian/Ubuntu the default ~/.bashrc starts
with a non-interactive short-circuit:
case $- in *i*) ;; *) return;; esac
Sourcing it from a non-interactive shell returns before any PATH export
below that guard runs. Node version managers like n and nvm append their
PATH line under that guard, so Hermes was capturing a PATH without
~/n/bin — and the terminal tool saw 'node: command not found' even when
node was on the user's interactive shell PATH.
Expand the auto-source list (when auto_source_bashrc is on) to:
~/.profile → ~/.bash_profile → ~/.bashrc
~/.profile and ~/.bash_profile have no interactivity guard — installers
that write their PATH there (n's n-install, nvm's curl installer on most
setups) take effect. ~/.bashrc still runs last to preserve behaviour for
users who put PATH logic there without the guard.
Added two tests covering the new behaviour plus an E2E test that spins up
a real LocalEnvironment with a guard-prefixed ~/.bashrc and a ~/.profile
PATH export, and verifies the captured snapshot PATH contains the profile
entry.
On fresh RHEL/Debian SSH sessions without linger, `systemctl --user
start hermes-gateway` fails with 'Failed to connect to bus: No medium
found' because /run/user/$UID/bus doesn't exist. Setup previously
showed a raw CalledProcessError and continued claiming success, so the
gateway never actually started.
systemd_start() and systemd_restart() now call _preflight_user_systemd()
for the user scope first:
- Bus socket already there → no-op (desktop / linger-enabled servers)
- Linger off → try loginctl enable-linger (works when polkit permits,
needs sudo otherwise), wait for socket
- Still unreachable → raise UserSystemdUnavailableError with a clean
remediation message pointing to sudo loginctl + hermes gateway run
as the foreground fallback
Setup's start/restart handlers and gateway_command() catch the new
exception and render the multi-line guidance instead of a traceback.
Multiple custom_providers entries sharing the same base_url + api_key
are now grouped into a single picker row. A local Ollama host with
per-model display names ("Ollama — GLM 5.1", "Ollama — Qwen3-coder",
"Ollama — Kimi K2", "Ollama — MiniMax M2.7") previously produced four
near-duplicate picker rows that differed only by suffix; now it appears
as one "Ollama" row with four models.
Key changes:
- Grouping key changed from slug-by-name to (base_url, api_key). Names
frequently differ per model while the endpoint stays the same.
- When the grouped endpoint matches current_base_url, the row's slug is
set to current_provider so picker-driven switches route through the
live credential pipeline (no re-resolution needed).
- Per-model suffix is stripped from the display name ("Ollama — X" →
"Ollama") via em-dash / " - " separators.
- Two groups with different api_keys at the same base_url (or otherwise
colliding on cleaned name) are disambiguated with a numeric suffix
(custom:openai, custom:openai-2) so both stay visible.
- current_base_url parameter plumbed through both gateway call sites.
Existing #8216, #11499, #13509 regressions covered (dict/list shapes
of models:, section-3/section-4 dedup, normalized list-format entries).
Salvaged from @davidvv's PR #9210 — the underlying code had diverged
~1400 commits since that PR was opened, so this is a reconstruction of
the same approach on current main rather than a clean cherry-pick.
Authorship preserved via --author on this commit.
Closes#9210
_normalize_custom_provider_entry silently drops the models field when it's
a list. Hand-edited configs (and the shape used by older Hermes versions)
still write models as a plain list of ids, so after the normalize pass the
entry reaches list_authenticated_providers() with no models and /model
shows the provider with (0) models — even though the underlying picker
code handles lists fine.
Convert list-format models into the empty-value dict shape the rest of
the pipeline already expects. Dict-format entries keep passing through
unchanged.
Repro (before the fix):
custom_providers:
- name: acme
base_url: https://api.example.com/v1
models: [foo, bar, baz]
/model shows "acme (0)"; bypassing normalize in list_authenticated_providers
returns three models, confirming the drop happens in normalize.
Adds four unit tests covering list→dict conversion, dict pass-through,
filtering of empty/non-string entries, and the empty-list case.
When user_name is stored as None (e.g. Telegram users without a
display name), dict.get('user_name', '') returns None because the
key exists — the default is only used for missing keys. This causes
a TypeError when the format specifier :<20 is applied to None.
Use `or ''` to coerce None to an empty string.
Fixes#7392

In list_authenticated_providers(), providers like qwen-oauth that use
OAuth authentication were incorrectly flagged as authenticated because
the env-var check fell back to models.dev provider env vars (e.g.
DASHSCOPE_API_KEY for alibaba). Any user with an alibaba API key would
see a ghost qwen-oauth entry in /model picker with 0 models listed.
Fix: skip providers whose auth_type is not api_key in the env-var
detection section (step 1). OAuth/external-process providers are
properly handled in step 2 (HERMES_OVERLAYS) which checks the auth store.
Port from openai/codex#18646.
Adds two flags to 'hermes chat' that fully isolate a run from user-level
configuration and rules:
* --ignore-user-config: skip ~/.hermes/config.yaml and fall back to
built-in defaults. Credentials in .env are still loaded so the agent
can actually call a provider.
* --ignore-rules: skip auto-injection of AGENTS.md, SOUL.md,
.cursorrules, and persistent memory (maps to AIAgent(skip_context_files=True,
skip_memory=True)).
Primary use cases:
- Reproducible CI runs that should not pick up developer-local config
- Third-party integrations (e.g. Chronicle in Codex) that bring their
own config and don't want user preferences leaking in
- Bug-report reproduction without the reporter's personal overrides
- Debugging: bisect 'was it my config?' vs 'real bug' in one command
Both flags are registered on the parent parser AND the 'chat' subparser
(with argparse.SUPPRESS on the subparser to avoid overwriting the parent
value when the flag is placed before the subcommand, matching the
existing --yolo/--worktree/--pass-session-id pattern).
Env vars HERMES_IGNORE_USER_CONFIG=1 and HERMES_IGNORE_RULES=1 are set
by cmd_chat BEFORE 'from cli import main' runs, which is critical
because cli.py evaluates CLI_CONFIG = load_cli_config() at module import
time. The cli.py / hermes_cli.config.load_cli_config() function checks
the env var and skips ~/.hermes/config.yaml when set.
Tests: 11 new tests in tests/hermes_cli/test_ignore_user_config_flags.py
covering the env gate, constructor wiring, cmd_chat simulation, and
argparse flag registration. All pass; existing hermes_cli + cli suites
unaffected (3005 pass, 2 pre-existing unrelated failures).
When a user manually sets fallback_model as a YAML list instead of a
dict, save_config_value() crashes with:
AttributeError: 'list' object has no attribute 'get'
at the fb.get('provider') call on hermes_cli/config.py.
The fix adds isinstance(fb, dict) so list-format values are treated as
unconfigured — the fallback_model comment block is appended to guide
correct usage — instead of crashing.
Fixes#4091

The Anthropic provider entry in PROVIDER_REGISTRY is the only standard
API-key provider missing a base_url_env_var. This causes the credential
pool to hardcode base_url to https://api.anthropic.com, ignoring
ANTHROPIC_BASE_URL from the environment.
When using a proxy (e.g. LiteLLM, custom gateway), subagent delegation
fails with 401 because:
1. _seed_from_env() creates pool entries with the hardcoded base_url
2. On error recovery, _swap_credential() overwrites the child agent's
proxy URL with the pool entry's api.anthropic.com
3. The proxy API key is sent to real Anthropic → authentication_error
Adding base_url_env_var="ANTHROPIC_BASE_URL" aligns Anthropic with the
20+ other providers that already have this field set (alibaba, gemini,
deepseek, xai, etc.).
Follow-up on helix4u's PR #14211:
- Flip default to true: narrowing toolsets=['web','browser'] expresses
'I want these extras', not 'silently strip MCP'. Parent MCP tools
(registered at runtime) should survive narrowing by default.
- Drop _config_version bump (22->23); additive nested key under
delegation.* is handled by _deep_merge, no migration needed.
- Update tests to reflect new default behavior.
New and newer models from models.dev now surface automatically in
/model (both hermes model CLI and the gateway Telegram/Discord picker)
for a curated set of secondary providers — no Hermes release required
when the registry publishes a new model.
Primary user-visible fix: on OpenCode Go, typing '/model mimo-v2.5-pro'
no longer silently fuzzy-corrects to 'mimo-v2-pro'. The exact match
against the merged models.dev catalog wins.
Scope (opt-in frozenset _MODELS_DEV_PREFERRED in hermes_cli/models.py):
opencode-go, opencode-zen, deepseek, kilocode, fireworks, mistral,
togetherai, cohere, perplexity, groq, nvidia, huggingface, zai,
gemini, google.
Explicitly NOT merged:
- openrouter and nous (never): curated list is already a hand-picked
subset / Portal is source of truth.
- xai, xiaomi, minimax, minimax-cn, kimi-coding, kimi-coding-cn,
alibaba, qwen-oauth (per-project decision to keep curated-only).
- providers with dedicated live-endpoint paths (copilot, anthropic,
ai-gateway, ollama-cloud, custom, stepfun, openai-codex) — those
paths already handle freshness themselves.
Changes:
- hermes_cli/models.py: add _MODELS_DEV_PREFERRED + _merge_with_models_dev
helper. provider_model_ids() branches on the set at its curated-fallback
return. Merge is models.dev-first, curated-only extras appended,
case-insensitive dedup, graceful fallback when models.dev is offline.
- hermes_cli/model_switch.py: list_authenticated_providers() calls the
same merge in both its code paths (PROVIDER_TO_MODELS_DEV loop +
HERMES_OVERLAYS loop). Picker AND validation-fallback both see
fresh entries.
- tests/hermes_cli/test_models_dev_preferred_merge.py (new): 13 tests —
merge-helper unit tests (empty/raise/order/dedup), opencode-go/zen
behavior, openrouter+nous explicitly guarded from merge.
- tests/hermes_cli/test_opencode_go_in_model_list.py: converted from
snapshot-style assertion to a behavior-based floor check, so it
doesn't break when models.dev publishes additional opencode-go
entries.
Addresses a report from @pfanis via Telegram: newer Xiaomi variants
on OpenCode Go weren't appearing in the /model picker, and /model
was silently routing requests for new variants to older ones.
Plugin slash commands now surface as first-class commands in every gateway
enumerator — Discord native slash picker, Telegram BotCommand menu, Slack
/hermes subcommand map — without a separate per-platform plugin API.
The existing 'command:<name>' gateway hook gains a decision protocol via
HookRegistry.emit_collect(): handlers that return a dict with
{'decision': 'deny'|'handled'|'rewrite'|'allow'} can intercept slash
command dispatch before core handling runs, unifying what would otherwise
have been a parallel 'pre_gateway_command' hook surface.
Changes:
- gateway/hooks.py: add HookRegistry.emit_collect() that fires the same
handler set as emit() but collects non-None return values. Backward
compatible — fire-and-forget telemetry hooks still work via emit().
- hermes_cli/plugins.py: add optional 'args_hint' param to
register_command() so plugins can opt into argument-aware native UI
registration (Discord arg picker, future platforms).
- hermes_cli/commands.py: add _iter_plugin_command_entries() helper and
merge plugin commands into telegram_bot_commands() and
slack_subcommand_map(). New is_gateway_known_command() recognizes both
built-in and plugin commands so the gateway hook fires for either.
- gateway/platforms/discord.py: extract _build_auto_slash_command helper
from the COMMAND_REGISTRY auto-register loop and reuse it for
plugin-registered commands. Built-in name conflicts are skipped.
- gateway/run.py: before normal slash dispatch, call emit_collect on
command:<canonical> and honor deny/handled/rewrite/allow decisions.
Hook now fires for plugin commands too.
- scripts/release.py: AUTHOR_MAP entry for @Magaav.
- Tests: emit_collect semantics, plugin command surfacing per platform,
decision protocol (deny/handled/rewrite/allow + non-dict tolerance),
Discord plugin auto-registration + conflict skipping, is_gateway_known_command.
Salvaged from #14131 (@Magaav). Original PR added a parallel
'pre_gateway_command' hook and a platform-keyed plugin command
registry; this re-implementation reuses the existing 'command:<name>'
hook and treats plugin commands as platform-agnostic so the same
capability reaches Telegram and Slack without new API surface.

Replace xiaomi/mimo-v2-pro with xiaomi/mimo-v2.5-pro and xiaomi/mimo-v2.5
in the OpenRouter fallback catalog and the nous provider model list.
Add matching DEFAULT_CONTEXT_LENGTHS entries (1M tokens each).
Adds security.allow_private_urls / HERMES_ALLOW_PRIVATE_URLS toggle so
users on OpenWrt routers, TUN-mode proxies (Clash/Mihomo/Sing-box),
corporate split-tunnel VPNs, and Tailscale networks — where DNS resolves
public domains to 198.18.0.0/15 or 100.64.0.0/10 — can use web_extract,
browser, vision URL fetching, and gateway media downloads.
Single toggle in tools/url_safety.py; all 23 is_safe_url() call sites
inherit automatically. Cached for process lifetime.
Cloud metadata endpoints stay ALWAYS blocked regardless of the toggle:
169.254.169.254 (AWS/GCP/Azure/DO/Oracle), 169.254.170.2 (AWS ECS task
IAM creds), 169.254.169.253 (Azure IMDS wire server), 100.100.100.200
(Alibaba), fd00:ec2::254 (AWS IPv6), the entire 169.254.0.0/16
link-local range, and the metadata.google.internal / metadata.goog
hostnames (checked pre-DNS so they can't be bypassed on networks where
those names resolve to local IPs).
Supersedes #3779 (narrower HERMES_ALLOW_RFC2544 for the same class of
users).

Copilot on #14138 flagged that the share report says '(file not found)'
when the log exists but is empty (either because the primary is empty
and no .1 rotation exists, or in the rare race where the file is
truncated between _resolve_log_path() and stat()).
- Split _primary_log_path() out of _resolve_log_path so both can share
the LOG_FILES/home math without duplication.
- _capture_log_snapshot now reports '(file empty)' when the primary
path exists on disk with zero bytes, and keeps '(file not found)'
for the truly-missing case.
Tests: rename test_returns_none_for_empty → test_empty_primary_reports_file_empty
with the new assertion, plus a race-path test that monkeypatches
_resolve_log_path to exercise the size==0 branch directly.
The salvaged status-bar skin keys were seeded on the default skin, but
_build_skin_config merges default.colors into every skin — so daylight
and warm-lightmode silently inherited silver status_bar_text (#C0C0C0)
on their light backgrounds, rendering as low-contrast gray on gray.
Drop the seven status_bar_{text,strong,dim,good,warn,bad,critical}
entries from the default skin's colors and let get_prompt_toolkit_style
_overrides fall back to banner_text / banner_title / banner_dim /
ui_ok / ui_warn / ui_error. Dark skins keep their explicit overrides
and render identically; light skins now inherit their own dark banner
colors for readable status-bar text.
Drop rebased test assumptions about theme-mode helpers removed on main and keep the status bar skin integration aligned with the current skin engine model.
Route prompt_toolkit status bar colors through the skin engine so /skin updates the status bar alongside the rest of the interactive TUI.
Add regression coverage for the new status bar style override keys and CLI style composition.
These thin wrappers around _capture_log_snapshot had zero production
callers after the snapshot refactor — run_debug_share uses snapshots
directly and collect_debug_report captures internally. The wrappers
also caused a performance regression: _read_log_tail read up to 512KB
and built full_text just to return tail_text.
Remove both wrappers and migrate TestReadFullLog → TestCaptureLogSnapshot
to test _capture_log_snapshot directly. Same coverage, tests the real
API instead of dead indirection.
Adapt the byte-boundary-safe truncation fix from PR #14040 by
taosiyuan163 into the new _capture_log_snapshot() code path: when
the truncation cut lands exactly on a line boundary, keep the first
retained line instead of unconditionally dropping it.
Also add a 2x max_bytes safety cap to the backward-reading loop to
prevent unbounded memory consumption when log files contain very long
lines (e.g. JSON blobs) with few newlines.
Based on #14040 by @taosiyuan163.
* fix(plugins): auto-coerce user-installed memory plugins to kind=exclusive
User-installed memory provider plugins at $HERMES_HOME/plugins/<name>/
were being dispatched to the general PluginManager, which has no
register_memory_provider method on PluginContext. Every startup logged:
Failed to load plugin 'mempalace': 'PluginContext' object has no
attribute 'register_memory_provider'
Bundled memory providers were already skipped via skip_names={memory,
context_engine} in discover_and_load, but user-installed ones weren't.
Fix: _parse_manifest now scans the plugin's __init__.py source for
'register_memory_provider' or 'MemoryProvider' (same heuristic as
plugins/memory/__init__.py:_is_memory_provider_dir) and auto-coerces
kind to 'exclusive' when the manifest didn't declare one explicitly.
This routes the plugin to plugins/memory discovery instead of the
general loader.
The escape hatch: if a manifest explicitly declares kind: standalone,
the heuristic doesn't override it.

* fix(nous): actionable CLI message when Nous 401 refresh fails
Mirrors the Anthropic 401 diagnostic pattern. When Nous returns 401
and the credential refresh (_try_refresh_nous_client_credentials)
also fails, the user used to see only the raw APIError. Now prints:
🔐 Nous 401 — Portal authentication failed.
Response: <truncated body>
Most likely: Portal OAuth expired, account out of credits, or
agent key revoked.
Troubleshooting:
• Re-authenticate: hermes login --provider nous
• Check credits / billing: https://portal.nousresearch.com
• Verify stored credentials: $HERMES_HOME/auth.json
• Switch providers temporarily: /model <model> --provider openrouter
Addresses the common 'my hermes model hangs' pattern where the user's
Portal OAuth expired and the CLI gave no hint about the next step.
Adds schema v7 'api_call_count' column. run_agent.py increments it by 1
per LLM API call, web_server analytics SQL aggregates it, frontend uses
the real counter instead of summing sessions.
The 'API Calls' card on the analytics dashboard previously displayed
COUNT(*) from the sessions table — the number of conversations, not
LLM requests. Each session makes 10-90 API calls through the tool loop,
so the reported number was ~30x lower than real.
Salvaged from PR #10140 (@kshitijk4poor). The cache-token accuracy
portions of the original PR were deferred — per-provider analytics is
the better path there, since cache_write_tokens and actual_cost_usd
are only reliably available from a subset of providers (Anthropic
native, Codex Responses, OpenRouter with usage.include).
Tests:
- schema_version v7 assertion
- migration v2 -> v7 adds api_call_count column with default 0
- update_token_counts increments api_call_count by provided delta
- absolute=True sets api_call_count directly
- /api/analytics/usage exposes total_api_calls in totals
- Replace async create_bind_task/poll_bind_result with synchronous
httpx.Client equivalents, eliminating manual event loop management
- Move _render_qr and full qr_register() entry-point into onboard.py,
mirroring the Feishu onboarding pattern
- Remove _qqbot_render_qr and _qqbot_qr_flow from gateway.py (~90 lines);
call site becomes a single qr_register() import
- Fix potential segfault: previous code called loop.close() in the EXPIRED
branch and again in the finally block (double-close crashed under uvloop)
* feat(state): auto-prune old sessions + VACUUM state.db at startup
state.db accumulates every session, message, and FTS5 index entry forever.
A heavy user (gateway + cron) reported 384MB with 982 sessions / 68K messages
causing slowdown; manual 'hermes sessions prune --older-than 7' + VACUUM
brought it to 43MB. The prune command and VACUUM are not wired to run
automatically anywhere — sessions grew unbounded until users noticed.
Changes:
- hermes_state.py: new state_meta key/value table, vacuum() method, and
maybe_auto_prune_and_vacuum() — idempotent via last-run timestamp in
state_meta so it only actually executes once per min_interval_hours
across all Hermes processes for a given HERMES_HOME. Never raises.
- hermes_cli/config.py: new 'sessions:' block in DEFAULT_CONFIG
(auto_prune=True, retention_days=90, vacuum_after_prune=True,
min_interval_hours=24). Added to _KNOWN_ROOT_KEYS.
- cli.py: call maintenance once at HermesCLI init (shared helper
_run_state_db_auto_maintenance reads config and delegates to DB).
- gateway/run.py: call maintenance once at GatewayRunner init.
- Docs: user-guide/sessions.md rewrites 'Automatic Cleanup' section.
Why VACUUM matters: SQLite does NOT shrink the file on DELETE — freed
pages get reused on next INSERT. Without VACUUM, a delete-heavy DB stays
bloated forever. VACUUM only runs when the prune actually removed rows,
so tight DBs don't pay the I/O cost.
Tests: 10 new tests in tests/test_hermes_state.py covering state_meta,
vacuum, idempotency, interval skipping, VACUUM-only-when-needed,
corrupt-marker recovery. All 246 existing state/config/gateway tests
still pass.
Verified E2E with real imports + isolated HERMES_HOME: DEFAULT_CONFIG
exposes the new block, load_config() returns it for fresh installs,
first call prunes+vacuums, second call within min_interval_hours skips,
and the state_meta marker persists across connection close/reopen.
* sessions.auto_prune defaults to false (opt-in)
Session history powers session_search recall across past conversations,
so silently pruning on startup could surprise users. Ship the machinery
disabled and let users opt in when they notice state.db is hurting
performance.
- DEFAULT_CONFIG.sessions.auto_prune: True → False
- Call-site fallbacks in cli.py and gateway/run.py match the new default
(so unmigrated configs still see off)
- Docs: flip 'Enable in config.yaml' framing + tip explains the tradeoff
Adds a first-class 'stepfun' API-key provider surfaced as Step Plan:
- Support Step Plan setup for both International and China regions
- Discover Step Plan models live from /step_plan/v1/models, with a
small coding-focused fallback catalog when discovery is unavailable
- Thread StepFun through provider metadata, setup persistence, status
and doctor output, auxiliary routing, and model normalization
- Add tests for provider resolution, model validation, metadata
mapping, and StepFun region/model persistence

* feat(plugins): pluggable image_gen backends + OpenAI provider
Adds a ImageGenProvider ABC so image generation backends register as
bundled plugins under `plugins/image_gen/<name>/`. The plugin scanner
gains three primitives to make this work generically:
- `kind:` manifest field (`standalone` | `backend` | `exclusive`).
Bundled `kind: backend` plugins auto-load — no `plugins.enabled`
incantation. User-installed backends stay opt-in.
- Path-derived keys: `plugins/image_gen/openai/` gets key
`image_gen/openai`, so a future `tts/openai` cannot collide.
- Depth-2 recursion into category namespaces (parent dirs without a
`plugin.yaml` of their own).
Includes `OpenAIImageGenProvider` as the first consumer (gpt-image-1.5
default, plus gpt-image-1, gpt-image-1-mini, DALL-E 3/2). Base64
responses save to `$HERMES_HOME/cache/images/`; URL responses pass
through.
FAL stays in-tree for this PR — a follow-up ports it into
`plugins/image_gen/fal/` so the in-tree `image_generation_tool.py`
slims down. The dispatch shim in `_handle_image_generate` only fires
when `image_gen.provider` is explicitly set to a non-FAL value, so
existing FAL setups are untouched.
- 41 unit tests (scanner recursion, kind parsing, gate logic,
registry, OpenAI payload shapes)
- E2E smoke verified: bundled plugin autoloads, registers, and
`_handle_image_generate` routes to OpenAI when configured
* fix(image_gen/openai): don't send response_format to gpt-image-*
The live API rejects it: 'Unknown parameter: response_format'
(verified 2026-04-21 with gpt-image-1.5). gpt-image-* models return
b64_json unconditionally, so the parameter was both unnecessary and
actively broken.
* feat(image_gen/openai): gpt-image-2 only, drop legacy catalog
gpt-image-2 is the latest/best OpenAI image model (released 2026-04-21)
and there's no reason to expose the older gpt-image-1.5 / gpt-image-1 /
dall-e-3 / dall-e-2 alongside it — slower, lower quality, or awkward
(dall-e-2 squares only). Trim the catalog down to a single model.
Live-verified end-to-end: landscape 1536x1024 render of a Moog-style
synth matches prompt exactly, 2.4MB PNG saved to cache.
* feat(image_gen/openai): expose gpt-image-2 as three quality tiers
Users pick speed/fidelity via the normal model picker instead of a
hidden quality knob. All three tier IDs resolve to the single underlying
gpt-image-2 API model with a different quality parameter:
gpt-image-2-low ~15s fast iteration
gpt-image-2-medium ~40s default
gpt-image-2-high ~2min highest fidelity
Live-measured on OpenAI's API today: 15.4s / 40.8s / 116.9s for the
same 1024x1024 prompt.
Config:
image_gen.openai.model: gpt-image-2-high
# or
image_gen.model: gpt-image-2-low
# or env var for scripts/tests
OPENAI_IMAGE_MODEL=gpt-image-2-medium
Live-verified end-to-end with the low tier: 18.8s landscape render of a
golden retriever in wildflowers, vision-confirmed exact match.
* feat(tools_config): plugin image_gen providers inject themselves into picker
'hermes tools' → Image Generation now shows plugin-registered backends
alongside Nous Subscription and FAL.ai without tools_config.py needing
to know about them. OpenAI appears as a third option today; future
backends appear automatically as they're added.
Mechanism:
- ImageGenProvider gains an optional get_setup_schema() hook
(name, badge, tag, env_vars). Default derived from display_name.
- tools_config._plugin_image_gen_providers() pulls the schemas from
every registered non-FAL plugin provider.
- _visible_providers() appends those rows when rendering the Image
Generation category.
- _configure_provider() handles the new image_gen_plugin_name marker:
writes image_gen.provider and routes to the plugin's list_models()
catalog for the model picker.
- _toolset_needs_configuration_prompt('image_gen') stops demanding a
FAL key when any plugin provider reports is_available().
FAL is skipped in the plugin path because it already has hardcoded
TOOL_CATEGORIES rows — when it gets ported to a plugin in a follow-up
PR the hardcoded rows go away and it surfaces through the same path
as OpenAI.
Verified live: picker shows Nous Subscription / FAL.ai / OpenAI.
Picking OpenAI prompts for OPENAI_API_KEY, then shows the
gpt-image-2-low/medium/high model picker sourced from the plugin.
397 tests pass across plugins/, tools_config, registry, and picker.
* fix(image_gen): close final gaps for plugin-backend parity with FAL
Two small places that still hardcoded FAL:
- hermes_cli/setup.py status line: an OpenAI-only setup showed
'Image Generation: missing FAL_KEY'. Now probes plugin providers
and reports '(OpenAI)' when one is_available() — or falls back to
'missing FAL_KEY or OPENAI_API_KEY' if nothing is configured.
- image_generate tool schema description: said 'using FAL.ai, default
FLUX 2 Klein 9B'. Rewrote provider-neutral — 'backend and model are
user-configured' — and notes the 'image' field can be a URL or an
absolute path, which the gateway delivers either way via
extract_local_files().
Surfaces the free variant alongside the paid minimax-m2.5 entry in
both the OPENROUTER_MODELS fallback snapshot and the nous/openrouter
provider model list.
Remove nvidia/nemotron-3-super-120b-a12b:free, arcee-ai/trinity-large-preview:free,
and openrouter/elephant-alpha from _PROVIDER_MODELS['nous']. The paid nemotron and
arcee-thinking variants remain.
Wire the auxiliary client (compaction, vision, session search, web extract)
to the Nous Portal's curated recommended-models endpoint when running on
Nous Portal, with a TTL-cached fetch that mirrors how we pull /models for
pricing.
hermes_cli/models.py
- fetch_nous_recommended_models(portal_base_url, force_refresh=False)
10-minute TTL cache, keyed per portal URL (staging vs prod don't
collide). Public endpoint, no auth required. Returns {} on any
failure so callers always get a dict.
- get_nous_recommended_aux_model(vision, free_tier=None, ...)
Tier-aware pick from the payload:
- Paid tier → paidRecommended{Vision,Compaction}Model, falling back
to freeRecommended* when the paid field is null (common during
staged rollouts of new paid models).
- Free tier → freeRecommended* only, never leaks paid models.
When free_tier is None, auto-detects via the existing
check_nous_free_tier() helper (already cached 3 min against
/api/oauth/account). Detection errors default to paid so we never
silently downgrade a paying user.
agent/auxiliary_client.py — _try_nous()
- Replaces the hardcoded xiaomi/mimo free-tier branch with a single call
to get_nous_recommended_aux_model(vision=vision).
- Falls back to _NOUS_MODEL (google/gemini-3-flash-preview) when the
Portal is unreachable or returns a null recommendation.
- The Portal is now the source of truth for aux model selection; the
xiaomi allowlist we used to carry is effectively dead.
Tests (15 new)
- tests/hermes_cli/test_models.py::TestNousRecommendedModels
Fetch caching, per-portal keying, network failure, force_refresh;
paid-prefers-paid, paid-falls-to-free, free-never-leaks-paid,
auto-detect, detection-error → paid default, null/blank modelName
handling.
- tests/agent/test_auxiliary_client.py::TestNousAuxiliaryRefresh
_try_nous honors Portal recommendation for text + vision, falls
back to google/gemini-3-flash-preview on None or exception.
Behavior won't visibly change today — both tier recommendations currently
point at google/gemini-3-flash-preview — but the moment the Portal ships
a better paid recommendation, subscribers pick it up within 10 minutes
without a Hermes release.
Drop _NOUS_ALLOWED_FREE_MODELS + filter_nous_free_models and its two call
sites. Whatever Nous Portal prices as free now shows up in the picker as-is
— no local allowlist gatekeeping. Free-tier partitioning (paid vs free in
the menu) still runs via partition_nous_models_by_tier.
Follow-ups after salvaging xiaoqiang243's kimi-for-coding patches:
- KIMI_CODE_BASE_URL: drop trailing /v1 (was /coding/v1).
The /coding endpoint speaks Anthropic Messages, and the Anthropic SDK
appends /v1/messages internally. /coding/v1 + SDK suffix produced
/coding/v1/v1/messages (a 404). /coding + SDK suffix now yields
/coding/v1/messages correctly.
- kimi-coding ProviderConfig: keep legacy default api.moonshot.ai/v1 so
non-sk-kimi- moonshot keys still authenticate. sk-kimi- keys are
already redirected to api.kimi.com/coding via _resolve_kimi_base_url.
- doctor.py: update Kimi UA to claude-code/0.1.0 (was KimiCLI/1.30.0)
and rewrite /coding base URLs to /coding/v1 for the /models health
check (Anthropic surface has no /models).
- test_kimi_env_vars: accept KIMI_CODING_API_KEY as a secondary env var.
E2E verified:
sk-kimi-<key> → https://api.kimi.com/coding/v1/messages (Anthropic)
sk-<legacy> → https://api.moonshot.ai/v1/chat/completions (OpenAI)
UA: claude-code/0.1.0, x-api-key: <sk-kimi-*>
A single global MAX_TEXT_LENGTH = 4000 truncated every TTS provider at
4000 chars, causing long inputs to be silently chopped even though the
underlying APIs allow much more:
- OpenAI: 4096
- xAI: 15000
- MiniMax: 10000
- ElevenLabs: 5000 / 10000 / 30000 / 40000 (model-aware)
- Gemini: ~5000
- Edge: ~5000
The schema description also told the model 'Keep under 4000 characters',
which encouraged the agent to self-chunk long briefs into multiple TTS
calls (producing 3 separate audio files instead of one).
New behavior:
- PROVIDER_MAX_TEXT_LENGTH table + ELEVENLABS_MODEL_MAX_TEXT_LENGTH
encode the documented per-provider limits.
- _resolve_max_text_length(provider, cfg) resolves:
1. tts.<provider>.max_text_length user override
2. ElevenLabs model_id lookup
3. provider default
4. 4000 fallback
- text_to_speech_tool() and stream_tts_to_speaker() both call the
resolver; old MAX_TEXT_LENGTH alias kept for back-compat.
- Schema description no longer hardcodes 4000.
Tests: 27 new unit + E2E tests; all 53 existing TTS tests and 253
voice-command/voice-cli tests still pass.
Adds role='leaf'|'orchestrator' to delegate_task. With max_spawn_depth>=2,
an orchestrator child retains the 'delegation' toolset and can spawn its
own workers; leaf children cannot delegate further (identical to today).
Default posture is flat — max_spawn_depth=1 means a depth-0 parent's
children land at the depth-1 floor and orchestrator role silently
degrades to leaf. Users opt into nested delegation by raising
max_spawn_depth to 2 or 3 in config.yaml.
Also threads acp_command/acp_args through the main agent loop's delegate
dispatch (previously silently dropped in the schema) via a new
_dispatch_delegate_task helper, and adds a DelegateEvent enum with
legacy-string back-compat for gateway/ACP/CLI progress consumers.
Config (hermes_cli/config.py defaults):
delegation.max_concurrent_children: 3 # floor-only, no upper cap
delegation.max_spawn_depth: 1 # 1=flat (default), 2-3 unlock nested
delegation.orchestrator_enabled: true # global kill switch
Salvaged from @pefontana's PR #11215. Overrides vs. the original PR:
concurrency stays at 3 (PR bumped to 5 + cap 8 — we keep the floor only,
no hard ceiling); max_spawn_depth defaults to 1 (PR defaulted to 2 which
silently enabled one level of orchestration for every user).

Reported during TUI v2 blitz testing: typing `@folder:` in the composer
pulled up .dockerignore, .env, .gitignore, and every other file in the
cwd alongside the actual directories. The completion loop yielded every
entry regardless of the explicit prefix and auto-rewrote each completion
to @file: vs @folder: based on is_dir — defeating the user's choice.
Also fixed a pre-existing adjacent bug: a bare `@file:` or `@folder:`
(no path) used expanded=="." as both search_dir AND match_prefix,
filtering the list to dotfiles only. When expanded is empty or ".",
search in cwd with no prefix filter.
- want_dir = prefix == "@folder:" drives an explicit is_dir filter
- preserve the typed prefix in completion text instead of rewriting
- three regression tests cover: folder-only, file-only, and the bare-
prefix case where completions keep the `@folder:` prefix
DNS rebinding attack: a victim browser that has the dashboard (or the
WhatsApp bridge) open could be tricked into fetching from an
attacker-controlled hostname that TTL-flips to 127.0.0.1. Same-origin
and CORS checks don't help — the browser now treats the attacker origin
as same-origin with the local service. Validating the Host header at
the app layer rejects any request whose Host isn't one we bound for.
Changes:
hermes_cli/web_server.py:
- New host_header_middleware runs before auth_middleware. Reads
app.state.bound_host (set by start_server) and rejects requests
whose Host header doesn't match the bound interface with HTTP 400.
- Loopback binds accept localhost / 127.0.0.1 / ::1. Non-loopback
binds require exact match. 0.0.0.0 binds skip the check (explicit
--insecure opt-in; no app-layer defence possible).
- IPv6 bracket notation parsed correctly: [::1] and [::1]:9119 both
accepted.
scripts/whatsapp-bridge/bridge.js:
- Express middleware rejects non-loopback Host headers. Bridge
already binds 127.0.0.1-only, this adds the complementary app-layer
check for DNS rebinding defence.
Tests: 8 new in tests/hermes_cli/test_web_server_host_header.py
covering loopback/non-loopback/zero-zero binds, IPv6 brackets, case
insensitivity, and end-to-end middleware rejection via TestClient.
Reported in GHSA-ppp5-vxwm-4cf7 by @bupt-Yy-young. Hardening — not
CVE per SECURITY.md §3. The dashboard's main trust boundary is the
loopback bind + session token; DNS rebinding defeats the bind assumption
but not the token (since the rebinding browser still sees a first-party
fetch to 127.0.0.1 with the token-gated API). Host-header validation
adds the missing belt-and-braces layer.
Two call sites still used a raw substring check to identify ollama.com:
hermes_cli/runtime_provider.py:496:
_is_ollama_url = "ollama.com" in base_url.lower()
run_agent.py:6127:
if fb_base_url_hint and "ollama.com" in fb_base_url_hint.lower() ...
Same bug class as GHSA-xf8p-v2cg-h7h5 (OpenRouter substring leak), which
was fixed in commit dbb7e00e via base_url_host_matches() across the
codebase. The earlier sweep missed these two Ollama sites. Self-discovered
during April 2026 security-advisory triage; filed as GHSA-76xc-57q6-vm5m.
Impact is narrow — requires a user with OLLAMA_API_KEY configured AND a
custom base_url whose path or look-alike host contains 'ollama.com'.
Users on default provider flows are unaffected. Filed as a draft advisory
to use the private-fork flow; not CVE-worthy on its own.
Fix is mechanical: replace substring check with base_url_host_matches
at both sites. Same helper the rest of the codebase uses.
Tests: 67 -> 71 passing. 7 new host-matcher cases in
tests/test_base_url_hostname.py (path injection, lookalike host,
localtest.me subdomain, ollama.ai TLD confusion, localhost, genuine
ollama.com, api.ollama.com subdomain) + 4 call-site tests in
tests/hermes_cli/test_runtime_provider_resolution.py verifying
OLLAMA_API_KEY is selected only when base_url actually targets
ollama.com.
Fixes GHSA-76xc-57q6-vm5m
Gateway /model <name> --provider opencode-go (or any provider whose /models
endpoint is down, 404s, or doesn't exist) silently failed. validate_requested_model
returned accepted=False whenever fetch_api_models returned None, switch_model
returned success=False, and the gateway never wrote _session_model_overrides —
so the switch appeared to succeed in the error message flow but the next turn
kept calling the old provider.
The validator already had static-catalog fallbacks for MiniMax and Codex
(providers without a /models endpoint). Extended the same pattern as the
terminal fallback: when the live probe fails, consult provider_model_ids()
for the curated catalog. Known models → accepted+recognized. Close typos →
auto-corrected. Unknown models → soft-accepted with a 'Not in curated
catalog' warning. Providers with no catalog at all → soft-accepted with a
generic 'Note:' warning, finally honoring the in-code comment ('Accept and
persist, but warn') that had been lying since it was written.
Tests: 7 new tests in test_opencode_go_validation_fallback.py covering the
catalog lookup, case-insensitive match, auto-correct, unknown-with-suggestion,
unknown-without-suggestion, and no-catalog paths. TestValidateApiFallback in
test_model_validation.py updated — its four 'rejected_when_api_down' tests
were encoding exactly the bug being fixed.
* feat(models): hide OpenRouter models that don't advertise tool support
Port from Kilo-Org/kilocode#9068.
hermes-agent is tool-calling-first — every provider path assumes the
model can invoke tools. Models whose OpenRouter supported_parameters
doesn't include 'tools' (e.g. image-only or completion-only models)
cannot be driven by the agent loop and fail at the first tool call.
Filter them out of fetch_openrouter_models() so they never appear in
the model picker (`hermes model`, setup wizard, /model slash command).
Permissive when the field is missing — OpenRouter-compatible gateways
(Nous Portal, private mirrors, older snapshots) don't always populate
supported_parameters. Treat missing as 'unknown → allow' rather than
silently emptying the picker on those gateways. Only hide models
whose supported_parameters is an explicit list that omits tools.
Tests cover: tools present → kept, tools absent → dropped, field
missing → kept, malformed non-list → kept, non-dict item → kept,
empty list → dropped.
* refactor(acp): validate method_id against advertised provider in authenticate()
Previously authenticate() accepted any method_id whenever the server had
provider credentials configured. This was not a vulnerability under the
personal-assistant trust model (ACP is stdio-only, local-trust — anything
that can reach the transport is already code-execution-equivalent to the
user), but it was sloppy API hygiene: the advertised auth_methods list
from initialize() was effectively ignored.
Now authenticate() only returns AuthenticateResponse when method_id
matches the currently-advertised provider (case-insensitive). Mismatched
or missing method_id returns None, consistent with the no-credentials
case.
Raised by xeloxa via GHSA-g5pf-8w9m-h72x. Declined as a CVE
(ACP transport is stdio, local-trust model), but the correctness fix is
worth having on its own.
Follow-up to PR #2504. The original fix covered the two direct FAL_KEY
checks in image_generation_tool but left four other call sites intact,
including the managed-gateway gate where a whitespace-only FAL_KEY
falsely claimed 'user has direct FAL' and *skipped* the Nous managed
gateway fallback entirely.
Introduce fal_key_is_configured() in tools/tool_backend_helpers.py as a
single source of truth (consults os.environ, falls back to .env for
CLI-setup paths) and route every FAL_KEY presence check through it:
- tools/image_generation_tool.py : _resolve_managed_fal_gateway,
image_generate_tool's upfront check, check_fal_api_key
- hermes_cli/nous_subscription.py : direct_fal detection, selected
toolset gating, tools_ready map
- hermes_cli/tools_config.py : image_gen needs-setup check
Verified by extending tests/tools/test_image_generation_env.py and by
E2E exercising whitespace + managed-gateway composition directly.
OpenCode Go's published model list (opencode.ai/docs/go) includes kimi-k2.6,
qwen3.5-plus, and qwen3.6-plus, but Hermes' curated lists didn't carry them.
When the live /models probe fails during `hermes model`, users fell back to
the stale curated list and had to type newer models via 'Enter custom model
name'.
Adds kimi-k2.6 (now first in the Go list), qwen3.6-plus, and qwen3.5-plus
to both the model picker (hermes_cli/models.py) and setup defaults
(hermes_cli/setup.py). All routed through the existing opencode-go
chat_completions path — no api_mode changes needed.
Every credential source Hermes reads from now behaves identically on
`hermes auth remove`: the pool entry stays gone across fresh load_pool()
calls, even when the underlying external state (env var, OAuth file,
auth.json block, config entry) is still present.
Before this, auth_remove_command was a 110-line if/elif with five
special cases, and three more sources (qwen-cli, copilot, custom
config) had no removal handler at all — their pool entries silently
resurrected on the next invocation. Even the handled cases diverged:
codex suppressed, anthropic deleted-without-suppressing, nous cleared
without suppressing. Each new provider added a new gap.
What's new:
agent/credential_sources.py — RemovalStep registry, one entry per
source (env, claude_code, hermes_pkce, nous device_code, codex
device_code, qwen-cli, copilot gh_cli + env vars, custom config).
auth_remove_command dispatches uniformly via find_removal_step().
Changes elsewhere:
agent/credential_pool.py — every upsert in _seed_from_env,
_seed_from_singletons, and _seed_custom_pool now gates on
is_source_suppressed(provider, source) via a shared helper.
hermes_cli/auth_commands.py — auth_remove_command reduced to 25
lines of dispatch; auth_add_command now clears ALL suppressions for
the provider on re-add (was env:* only).
Copilot is special: the same token is seeded twice (gh_cli via
_seed_from_singletons + env:<VAR> via _seed_from_env), so removing one
entry without suppressing the other variants lets the duplicate
resurrect. The copilot RemovalStep suppresses gh_cli + all three env
variants (COPILOT_GITHUB_TOKEN, GH_TOKEN, GITHUB_TOKEN) at once.
Tests: 11 new unit tests + 4059 existing pass. 12 E2E scenarios cover
every source in isolated HERMES_HOME with simulated fresh processes.
Removing an env-seeded credential only cleared ~/.hermes/.env and the
current process's os.environ, leaving shell-exported vars (shell profile,
systemd EnvironmentFile, launchd plist) to resurrect the entry on the
next load_pool() call. This matched the pre-#11485 codex behaviour.
Now we suppress env:<VAR> in auth.json on remove, gate _seed_from_env()
behind is_source_suppressed(), clear env:* suppressions on auth add,
and print a diagnostic pointing at the shell when the var lives there.
Applies to every env:* seeded credential (xai, deepseek, moonshot, zai,
nvidia, openrouter, anthropic, etc.), not just xai.
Reported by @teknium1 from community user 'Artificial Brain' — couldn't
remove their xAI key via hermes auth remove.
Builds on @AxDSan's PR #2109 to finish the KittenTTS wiring so the
provider behaves like every other TTS backend end to end.
- tools/tts_tool.py: `_check_kittentts_available()` helper and wire
into `check_tts_requirements()`; extend Opus-conversion list to
include kittentts (WAV → Opus for Telegram voice bubbles); point the
missing-package error at `hermes setup tts`.
- hermes_cli/tools_config.py: add KittenTTS entry to the "Text-to-Speech"
toolset picker, with a `kittentts` post_setup hook that auto-installs
the wheel + soundfile via pip.
- hermes_cli/setup.py: `_install_kittentts_deps()`, new choice + install
flow in `_setup_tts_provider()`, provider_labels entry, and status row
in the `hermes setup` summary.
- website/docs/user-guide/features/tts.md: add KittenTTS to the provider
table, config example, ffmpeg note, and the zero-config voice-bubble tip.
- tests/tools/test_tts_kittentts.py: 10 unit tests covering generation,
model caching, config passthrough, ffmpeg conversion, availability
detection, and the missing-package dispatcher branch.
E2E verified against the real `kittentts` wheel:
- WAV direct output (pcm_s16le, 24kHz mono)
- MP3 conversion via ffmpeg (from WAV)
- Telegram flow (provider in Opus-conversion list) produces
`codec_name=opus`, 48kHz mono, `voice_compatible=True`, and the
`[[audio_as_voice]]` marker
- check_tts_requirements() returns True when kittentts is installed
Follow-up to the redundant-imports sweep. _install_hangup_protection
used to import get_hermes_home locally; the sweep hoisted it to the
module-level binding already present at line 164.
test_non_fatal_if_log_setup_fails monkeypatches
hermes_cli.config.get_hermes_home to raise, which only works when the
function late-binds its lookup. The hoisted version captures the
reference at import time and bypasses the monkeypatch.
Restore the local import (with a distinct local alias) so the test
seam works and the stdio-untouched-on-setup-failure invariant is
actually exercised.
Full AST-based scan of all .py files to find every case where a module
or name is imported locally inside a function body but is already
available at module level. This is the second pass — the first commit
handled the known cases from the lint report; this one catches
everything else.

* feat(skills): inject absolute skill dir and expand ${HERMES_SKILL_DIR} templates
When a skill loads, the activation message now exposes the absolute
skill directory and substitutes ${HERMES_SKILL_DIR} /
${HERMES_SESSION_ID} tokens in the SKILL.md body, so skills with
bundled scripts can instruct the agent to run them by absolute path
without an extra skill_view round-trip.
Also adds opt-in inline-shell expansion: !`cmd` snippets in SKILL.md
are pre-executed (with the skill directory as CWD) and their stdout is
inlined into the message before the agent reads it. Off by default —
enable via skills.inline_shell in config.yaml — because any snippet
runs on the host without approval.
Changes:
- agent/skill_commands.py: template substitution, inline-shell
expansion, absolute skill-dir header, supporting-files list now
shows both relative and absolute forms.
- hermes_cli/config.py: new skills.template_vars,
skills.inline_shell, skills.inline_shell_timeout knobs.
- tests/agent/test_skill_commands.py: coverage for header, both
template tokens (present and missing session id), template_vars
disable, inline-shell default-off, enabled, CWD, and timeout.
- website/docs/developer-guide/creating-skills.md: documents the
template tokens, the absolute-path header, and the opt-in inline
shell with its security caveat.
Validation: tests/agent/ 1591 passed (includes 9 new tests).
E2E: loaded a real skill in an isolated HERMES_HOME; confirmed
${HERMES_SKILL_DIR} resolves to the absolute path, ${HERMES_SESSION_ID}
resolves to the passed task_id, !`date` runs when opt-in is set, and
stays literal when it isn't.
* feat(terminal): source ~/.bashrc (and user-listed init files) into session snapshot
bash login shells don't source ~/.bashrc, so tools that install themselves
there — nvm, asdf, pyenv, cargo, custom PATH exports — stay invisible to
the environment snapshot Hermes builds once per session. Under systemd
or any context with a minimal parent env, that surfaces as
'node: command not found' in the terminal tool even though the binary
is reachable from every interactive shell on the machine.
Changes:
- tools/environments/local.py: before the login-shell snapshot bootstrap
runs, prepend guarded 'source <file>' lines for each resolved init
file. Missing files are skipped, each source is wrapped with a
'[ -r ... ] && . ... || true' guard so a broken rc can't abort the
bootstrap.
- hermes_cli/config.py: new terminal.shell_init_files (explicit list,
supports ~ and ${VAR}) and terminal.auto_source_bashrc (default on)
knobs. When shell_init_files is set it takes precedence; when it's
empty and auto_source_bashrc is on, ~/.bashrc gets auto-sourced.
- tests/tools/test_local_shell_init.py: 10 tests covering the resolver
(auto-bashrc, missing file, explicit override, ~/${VAR} expansion,
opt-out) and the prelude builder (quoting, guarded sourcing), plus
a real-LocalEnvironment snapshot test that confirms exports in the
init file land in subsequent commands' environment.
- website/docs/reference/faq.md: documents the fix in Troubleshooting,
including the zsh-user pattern of sourcing ~/.zshrc or nvm.sh
directly via shell_init_files.
Validation: 10/10 new tests pass; tests/tools/test_local_*.py 40/40
pass; tests/agent/ 1591/1591 pass; tests/hermes_cli/test_config.py
50/50 pass. E2E in an isolated HERMES_HOME: confirmed that a fake
~/.bashrc setting a marker var and PATH addition shows up in a real
LocalEnvironment().execute() call, that auto_source_bashrc=false
suppresses it, that an explicit shell_init_files entry wins over the
auto default, and that a missing bashrc is silently skipped.
The re-pair branch had a redundant 'import shutil' inside cmd_whatsapp,
which made shutil a function-local throughout the whole scope. The
earlier 'shutil.which("npm")' call at the dependency-install step then
crashed with UnboundLocalError before control ever reached the local
import.
shutil is already imported at module level (line 48), so the local
import was dead code anyway. Drop it.
The WhatsApp bridge depends on @whiskeysockets/baileys pulled directly
from a GitHub commit tarball, which on slower connections or when
GitHub is sluggish routinely exceeds 120s. The hardcoded timeout
surfaced as a raw TimeoutExpired traceback during 'hermes whatsapp'
setup.
Switch to the same pattern used by the TUI npm install at line
~945: no timeout, --no-fund/--no-audit/--progress=false to keep
output clean, stderr captured and tailed on failure. Also resolve
npm via shutil.which so missing Node.js gives a clean error instead
of FileNotFoundError, and handle Ctrl+C cleanly.

Delete the stale literal `_PROVIDER_MODELS["ai-gateway"]` (gpt-5,
gemini-2.5-pro, claude-4.5 — outdated the moment PR #13223 landed with
its curated `AI_GATEWAY_MODELS` snapshot) and derive it from
`AI_GATEWAY_MODELS` instead, so the picker tuples and the bare-id
fallback catalog stay in sync automatically. Also fixes
`get_default_model_for_provider('ai-gateway')` to return kimi-k2.6
(the curated recommendation) instead of claude-opus-4.6.
Aslaaen's fix in the original PR covered _detect_api_mode_for_url and the
two openai/xai sites in run_agent.py. This finishes the sweep: the same
substring-match false-positive class (e.g. https://api.openai.com.evil/v1,
https://proxy/api.openai.com/v1, https://api.anthropic.com.example/v1)
existed in eight more call sites, and the hostname helper was duplicated
in two modules.
- utils: add shared base_url_hostname() (single source of truth).
- hermes_cli/runtime_provider, run_agent: drop local duplicates, import
from utils. Reuse the cached AIAgent._base_url_hostname attribute
everywhere it's already populated.
- agent/auxiliary_client: switch codex-wrap auto-detect, max_completion_tokens
gate (auxiliary_max_tokens_param), and custom-endpoint max_tokens kwarg
selection to hostname equality.
- run_agent: native-anthropic check in the Claude-style model branch
and in the AIAgent init provider-auto-detect branch.
- agent/model_metadata: Anthropic /v1/models context-length lookup.
- hermes_cli/providers.determine_api_mode: anthropic / openai URL
heuristics for custom/unknown providers (the /anthropic path-suffix
convention for third-party gateways is preserved).
- tools/delegate_tool: anthropic detection for delegated subagent
runtimes.
- hermes_cli/setup, hermes_cli/tools_config: setup-wizard vision-endpoint
native-OpenAI detection (paired with deduping the repeated check into
a single is_native_openai boolean per branch).
Tests:
- tests/test_base_url_hostname.py covers the helper directly
(path-containing-host, host-suffix, trailing dot, port, case).
- tests/hermes_cli/test_determine_api_mode_hostname.py adds the same
regression class for determine_api_mode, plus a test that the
/anthropic third-party gateway convention still wins.
Also: add asslaenn5@gmail.com → Aslaaen to scripts/release.py AUTHOR_MAP.
Load-time sanitizer silently removed non-ASCII codepoints from any
env var ending in _API_KEY / _TOKEN / _SECRET / _KEY, turning
copy-paste artifacts (Unicode lookalikes, ZWSP, NBSP) into opaque
provider-side API_KEY_INVALID errors.
Warn once per key to stderr with the offending codepoints (U+XXXX)
and guidance to re-copy from the provider dashboard.
The original list was copied from OpenRouter conventions and didn't
match what Vercel actually hosts. Verified against the live
/v1/models endpoint (266 models):
- qwen/qwen3.6-plus → alibaba/qwen3.6-plus (Vercel hosts Qwen under alibaba/)
- z-ai/glm-5.1 → zai/glm-5.1 (no hyphen)
- x-ai/grok-4.20 → xai/grok-4.20-reasoning (no hyphen, picks reasoning variant)
- google/gemini-3-flash-preview → google/gemini-3-flash (no -preview suffix)
- moonshotai/kimi-k2.5 → moonshotai/kimi-k2.6 (newest available)
Vercel provides a d?to= redirect URL that routes users through their
team picker to the AI Gateway API keys management page. Using this
specific URL lands users directly on the "Create key" page instead of
the generic AI Gateway dashboard.
When the live Vercel AI Gateway catalog exposes a Moonshot model with
zero input AND output pricing, it's promoted to position #1 as the
recommended default — even if the exact ID isn't in the curated
AI_GATEWAY_MODELS list. This enables dynamic discovery of new free
Moonshot variants without requiring a PR to update curation.
Paid Moonshot models are unaffected; falls back to the normal curated
recommended tag when no free Moonshot is live.
Moves Vercel AI Gateway from the bottom of the list to near the top,
adjacent to other multi-model aggregators. The existing bottom
position was a result of the list growing by appending new providers
over time — the new position makes it more discoverable.
- Curated AI_GATEWAY_MODELS list in hermes_cli/models.py (OSS first,
kimi-k2.5 as recommended default).
- fetch_ai_gateway_models() filters the curated list against the live
/v1/models catalog; falls back to the snapshot on network failure.
- fetch_ai_gateway_pricing() translates Vercel's input/output field
names to the prompt/completion shape the shared picker expects;
carries input_cache_read / input_cache_write through unchanged.
- get_pricing_for_provider() now handles ai-gateway.
- _model_flow_ai_gateway() provides a guided URL prompt when no key
is set and a pricing-column picker; routes ai-gateway to it instead
of the generic api-key flow.
Users can declare shell scripts in config.yaml under a hooks: block that
fire on plugin-hook events (pre_tool_call, post_tool_call, pre_llm_call,
subagent_stop, etc). Scripts receive JSON on stdin, can return JSON on
stdout to block tool calls or inject context pre-LLM.
Key design:
- Registers closures on existing PluginManager._hooks dict — zero changes
to invoke_hook() call sites
- subprocess.run(shell=False) via shlex.split — no shell injection
- First-use consent per (event, command) pair, persisted to allowlist JSON
- Bypass via --accept-hooks, HERMES_ACCEPT_HOOKS=1, or hooks_auto_accept
- hermes hooks list/test/revoke/doctor CLI subcommands
- Adds subagent_stop hook event fired after delegate_task children exit
- Claude Code compatible response shapes accepted
Cherry-picked from PR #13143 by @pefontana.
Six small fixes, all valid review feedback:
- gatewayClient: onTimeout is now a class-field arrow so setTimeout gets a
stable reference — no per-request bind allocation (the whole point of
the original refactor).
- memory: growth rate was lifetime average of rss/uptime, which reports
phantom growth for stable processes. Now computed as delta since a
module-load baseline (STARTED_AT). Sanity-checked: 0.00 MB/hr at
steady-state, non-zero after an allocation.
- hermes_cli: NODE_OPTIONS merge is now token-aware — respects a
user-supplied --max-old-space-size (don't downgrade a deliberate 16GB
setting) and avoids duplicating --expose-gc.
- useVirtualHistory: if items shrink past the frozen range's start
mid-freeze (/clear, compaction), drop the freeze and fall through to
the normal range calc instead of collapsing to an empty mount.
- circularBuffer: throw on non-positive capacity instead of silently
producing NaN indices.
- debug slash help: /heapdump mentions HERMES_HEAPDUMP_DIR override
instead of hardcoding the default path.
Validation: tsc clean, eslint clean, vitest 102/102, growth-rate smoke
test confirms baseline=0 → post-alloc>0.
Long TUI sessions were crashing Node via V8 fatal-OOM once transcripts +
reasoning blobs crossed the default 1.5–4GB heap cap. This adds defense
in depth: a bigger heap, leak-proofing the RPC hot path, bounded
diagnostic buffers, automatic heap dumps at high-water marks, and
graceful signal / uncaught handlers.
## Changes
### Heap budget
- hermes_cli/main.py: `_launch_tui` now injects `NODE_OPTIONS=
--max-old-space-size=8192 --expose-gc` (appended — does not clobber
user-supplied NODE_OPTIONS). Covers both `node dist/entry.js` and
`tsx src/entry.tsx` launch paths.
- ui-tui/src/entry.tsx: shebang rewritten to
`#!/usr/bin/env -S node --max-old-space-size=8192 --expose-gc` as a
fallback when the binary is invoked directly.
### GatewayClient (ui-tui/src/gatewayClient.ts)
- `setMaxListeners(0)` — silences spurious warnings from React hook
subscribers.
- `logs` and `bufferedEvents` replaced with fixed-capacity
CircularBuffer — O(1) push, no splice(0, …) copies under load.
- RPC timeout refactor: `setTimeout(this.onTimeout.bind(this), …, id)`
replaces the inline arrow closure that captured `method`/`params`/
`resolve`/`reject` for the full 120 s request timeout. Each Pending
record now stores its own timeout handle, `.unref()`'d so stuck
timers never keep the event loop alive, and `rejectPending()` clears
them (previously leaked the timer itself).
### Memory diagnostics (new)
- ui-tui/src/lib/memory.ts: `performHeapDump()` +
`captureMemoryDiagnostics()`. Writes heap snapshot + JSON diag
sidecar to `~/.hermes/heapdumps/` (override via
`HERMES_HEAPDUMP_DIR`). Diagnostics are written first so we still get
useful data if the snapshot crashes on very large heaps.
Captures: detached V8 contexts (closure-leak signal), active
handles/requests (`process._getActiveHandles/_getActiveRequests`),
Linux `/proc/self/fd` count + `/proc/self/smaps_rollup`, heap growth
rate (MB/hr), and auto-classifies likely leak sources.
- ui-tui/src/lib/memoryMonitor.ts: 10 s interval polling heapUsed. At
1.5 GB writes an auto heap dump (trigger=`auto-high`); at 2.5 GB
writes a final dump and exits 137 before V8 fatal-OOMs so the user
can restart cleanly. Handle is `.unref()`'d so it never holds the
process open.
### Graceful exit (new)
- ui-tui/src/lib/gracefulExit.ts: SIGINT/SIGTERM/SIGHUP run registered
cleanups through a 4 s failsafe `setTimeout` that hard-exits if
cleanup hangs.
`uncaughtException` / `unhandledRejection` are logged to stderr
instead of crashing — a transient TUI render error should not kill
an in-flight agent turn.
### Slash commands (new)
- ui-tui/src/app/slash/commands/debug.ts:
- `/heapdump` — manual snapshot + diagnostics.
- `/mem` — live heap / rss / external / array-buffer / uptime panel.
- Registered in `ui-tui/src/app/slash/registry.ts`.
### Utility (new)
- ui-tui/src/lib/circularBuffer.ts: small fixed-capacity ring buffer
with `push` / `tail(n)` / `drain()` / `clear()`. Replaces the ad-hoc
`array.splice(0, len - MAX)` pattern.
## Validation
- tsc `--noEmit` clean
- `vitest run`: 15 files, 102 tests passing
- eslint clean on all touched/new files
- build produces executable `dist/entry.js` with preserved shebang
- smoke-tested: `HERMES_HEAPDUMP_DIR=… performHeapDump('manual')`
writes both a valid `.heapsnapshot` and a `.diagnostics.json`
containing detached-contexts, active-handles, smaps_rollup.
## Env knobs
- `HERMES_HEAPDUMP_DIR` — override snapshot output dir
- `HERMES_HEAPDUMP_ON_START=1` — dump once at boot
- existing `NODE_OPTIONS` is respected and appended, not replaced
Section 3 (user-defined endpoints) added the plain ep_name to seen_slugs
but not the custom:-prefixed slug. Section 4 generates custom:<name> via
custom_provider_slug() and checks seen_slugs — since the prefixed slug
was missing, the same provider appeared twice in /model.
Register custom_provider_slug(display_name).lower() in seen_slugs after
Section 3 emits a provider, so Section 4's dedup correctly suppresses
the duplicate.
Closes#12293.
