Google AI Studio's free tier (<= 250 req/day for gemini-2.5-flash) is
exhausted in a handful of agent turns, so the setup wizard now refuses
to wire up Gemini when the supplied key is on the free tier, and the
runtime 429 handler appends actionable billing guidance.
Setup-time probe (hermes_cli/main.py):
- `_model_flow_api_key_provider` fires one minimal generateContent call
when provider_id == 'gemini' and classifies the response as
free/paid/unknown via x-ratelimit-limit-requests-per-day header or
429 body containing 'free_tier'.
- Free -> print block message, refuse to save the provider, return.
- Paid -> 'Tier check: paid' and proceed.
- Unknown (network/auth error) -> 'could not verify', proceed anyway.
Runtime 429 handler (agent/gemini_native_adapter.py):
- `gemini_http_error` appends billing guidance when the 429 error body
mentions 'free_tier', catching users who bypass setup by putting
GOOGLE_API_KEY directly in .env.
Tests: 21 unit tests for the probe + error path, 4 tests for the
setup-flow block. All 67 existing gemini tests still pass.
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.

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.
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).
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

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-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.

Sweep ~74 redundant local imports across 21 files where the same module
was already imported at the top level. Also includes type fixes and lint
cleanups on the same branch.
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.

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.
- 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
Add kimi-k2.6 as the top model in kimi-coding, kimi-coding-cn, and
moonshot static provider lists (models.py, setup.py, main.py).
kimi-k2.5 retained alongside it.
Plugins now require explicit consent to load. Discovery still finds every
plugin — user-installed, bundled, and pip — so they all show up in
`hermes plugins` and `/plugins`, but the loader only instantiates
plugins whose name appears in `plugins.enabled` in config.yaml. This
removes the previous ambient-execution risk where a newly-installed or
bundled plugin could register hooks, tools, and commands on first run
without the user opting in.
The three-state model is now explicit:
enabled — in plugins.enabled, loads on next session
disabled — in plugins.disabled, never loads (wins over enabled)
not enabled — discovered but never opted in (default for new installs)
`hermes plugins install <repo>` prompts "Enable 'name' now? [y/N]"
(defaults to no). New `--enable` / `--no-enable` flags skip the prompt
for scripted installs. `hermes plugins enable/disable` manage both lists
so a disabled plugin stays explicitly off even if something later adds
it to enabled.
Config migration (schema v20 → v21): existing user plugins already
installed under ~/.hermes/plugins/ (minus anything in plugins.disabled)
are auto-grandfathered into plugins.enabled so upgrades don't silently
break working setups. Bundled plugins are NOT grandfathered — even
existing users have to opt in explicitly.
Also: HERMES_DISABLE_BUNDLED_PLUGINS env var removed (redundant with
opt-in default), cmd_list now shows bundled + user plugins together with
their three-state status, interactive UI tags bundled entries
[bundled], docs updated across plugins.md and built-in-plugins.md.
Validation: 442 plugin/config tests pass. E2E: fresh install discovers
disk-cleanup but does not load it; `hermes plugins enable disk-cleanup`
activates hooks; migration grandfathers existing user plugins correctly
while leaving bundled plugins off.
After a conversation gets compressed, run_agent's _compress_context ends
the parent session and creates a continuation child with the same logical
conversation. Every list affordance in the codebase (list_sessions_rich
with its default include_children=False, plus the CLI/TUI/gateway/ACP
surfaces on top of it) hid those children, and resume-by-ID on the old
root landed on a dead parent with no messages.
Fix: lineage-aware projection on the read path.
- hermes_state.py::get_compression_tip(session_id) — walk the chain
forward using parent.end_reason='compression' AND
child.started_at >= parent.ended_at. The timing guard separates
compression continuations from delegate subagents (which were created
while the parent was still live) without needing a schema migration.
- hermes_state.py::list_sessions_rich — new project_compression_tips
flag (default True). For each compressed root in the result, replace
surfaced fields (id, ended_at, end_reason, message_count,
tool_call_count, title, last_active, preview, model, system_prompt)
with the tip's values. Preserve the root's started_at so chronological
ordering stays stable. Projected rows carry _lineage_root_id for
downstream consumers. Pass False to get raw roots (admin/debug).
- hermes_cli/main.py::_resolve_session_by_name_or_id — project forward
after ID/title resolution, so users who remember an old root ID (from
notes, or from exit summaries produced before the sibling Bug 1 fix)
land on the live tip.
All downstream callers of list_sessions_rich benefit automatically:
- cli.py _list_recent_sessions (/resume, show_history affordance)
- hermes_cli/main.py sessions list / sessions browse
- tui_gateway session.list picker
- gateway/run.py /resume titled session listing
- tools/session_search_tool.py
- acp_adapter/session.py
Tests: 7 new in TestCompressionChainProjection covering full-chain walks,
delegate-child exclusion, tip surfacing with lineage tracking, raw-root
mode, chronological ordering, and broken-chain graceful fallback.
Verified live: ran a real _compress_context on a live Gemini-backed
session, confirmed the DB split, then verified
- db.list_sessions_rich surfaces tip with _lineage_root_id set
- hermes sessions list shows the tip, not the ended parent
- _resolve_session_by_name_or_id(old_root_id) -> tip_id
- _resolve_last_session -> tip_id
Addresses #10373.
The google-gemini-cli (Cloud Code Assist) and gemini (native API) model
pickers only offered gemini-2.5-*, so users picking Gemini 3 had to type
a custom model name — usually wrong (e.g. "gemini-3.1-pro"), producing
a 404 from cloudcode-pa.googleapis.com.
Replace the 2.5-* entries with the actual Code Assist / Gemini API
preview IDs: gemini-3.1-pro-preview, gemini-3-pro-preview,
gemini-3-flash-preview (and gemini-3.1-flash-lite-preview on native).
Update the hardcoded fallback in hermes_cli/main.py to match.
Copilot's menu retains gemini-2.5-pro — that catalog is Microsoft's.
External services can now push plain-text notifications to a user's chat
via the webhook adapter without invoking the agent. Set deliver_only=true
on a route and the rendered prompt template becomes the literal message
body — dispatched directly to the configured target (Telegram, Discord,
Slack, GitHub PR comment, etc.).
Reuses all existing webhook infrastructure: HMAC-SHA256 signature
validation, per-route rate limiting, idempotency cache, body-size limits,
template rendering with dot-notation, home-channel fallback. No new HTTP
server, no new auth scheme, no new port.
Use cases: Supabase/Firebase webhooks → user notifications, monitoring
alert forwarding, inter-agent pings, background job completion alerts.
Changes:
- gateway/platforms/webhook.py: new _direct_deliver() helper + early
dispatch branch in _handle_webhook when deliver_only=true. Startup
validation rejects deliver_only with deliver=log.
- hermes_cli/main.py + hermes_cli/webhook.go: --deliver-only flag on
subscribe; list/show output marks direct-delivery routes.
- website/docs/user-guide/messaging/webhooks.md: new Direct Delivery
Mode section with config example, CLI example, response codes.
- skills/devops/webhook-subscriptions/SKILL.md: document --deliver-only
with use cases (bumped to v1.1.0).
- tests/gateway/test_webhook_deliver_only.py: 14 new tests covering
agent bypass, template rendering, status codes, HMAC still enforced,
idempotency still applies, rate limit still applies, startup
validation, and direct-deliver dispatch.
Validation: 78 webhook tests pass (64 existing + 14 new). E2E verified
with real aiohttp server + real urllib POST — agent not invoked, target
adapter.send() called with rendered template, duplicate delivery_id
suppressed.
Closes the gap identified in PR #12117 (thanks to @H1an1 / Antenna team)
without adding a second HTTP ingress server.
Anthropic migrated their developer console from console.anthropic.com
to platform.claude.com. Two user-facing display URLs were still pointing
to the old domain:
- hermes_cli/main.py — API key prompt in the Anthropic model flow
- run_agent.py — 401 troubleshooting output
The OAuth token refresh endpoint was already migrated in PR #3246
(with fallback).
Spotted by @LucidPaths in PR #3237.
(Salvage of #3758 — dropped the setup.py hunk since that section was
refactored away and no longer contains the stale URL.)
The web dashboard (Vite/React frontend) is now built as a separate Nix
derivation and baked into the Hermes package. The build output is
installed to a standard location and exposed via the `HERMES_WEB_DIST`
environment variable, allowing the dashboard command to use pre-built
assets when available (e.g., in packaged releases) instead of rebuilding
on every invocation.
* Add setuptools build dep for legacy alibabacloud packages and updated
stale npm-deps hash
* Add HERMES_NODE env var to pin Node.js version
The TUI requires Node.js 20+ for regex `/v` flag support (used by
string-width). Instead of relying on PATH lookup, explicitly set
HERMES_NODE to the bundled Node 22 in the Nix wrapper, and add a
fallback check in the Python code to use HERMES_NODE if available.
Also upgrade container provisioning to Node 22 via NodeSource (Ubuntu
24.04 ships Node 18 which is EOL) and add a Nix check to verify the
wrapper and Node version at build time.
hermes update no longer dies when the controlling terminal closes
(SSH drop, shell close) during pip install. SIGHUP is set to SIG_IGN
for the duration of the update, and stdout/stderr are wrapped so writes
to a closed pipe are absorbed instead of cascading into process exit.
All update output is mirrored to ~/.hermes/logs/update.log so users can
see what happened after reconnecting.
SIGINT (Ctrl-C) and SIGTERM (systemd) are intentionally still honored —
those are deliberate cancellations, not accidents. In gateway mode the
helper is a no-op since the update is already detached.
POSIX preserves SIG_IGN across exec(), so pip and git subprocesses
inherit hangup protection automatically — no changes to subprocess
spawning needed.
Error messages that tell users to install optional extras now use
{sys.executable} -m pip install ... instead of a bare 'pip install
hermes-agent[extra]' string. Under the curl installer, bare 'pip'
resolves to system pip, which either fails with PEP 668
externally-managed-environment or installs into the wrong Python.
Affects: hermes dashboard, hermes web server startup, mcp_serve,
hermes doctor Bedrock check, CLI voice mode, voice_mode tool runtime
error, Discord voice-channel join failure message.
Follow-up to #11909: surface the legacy-unit warning where users are most
likely to see it. After a 'hermes update', if a pre-rename hermes.service
is still installed alongside the current hermes-gateway.service, print
the list of legacy units + the 'hermes gateway migrate-legacy' command.
Profile-safe: reuses _find_legacy_hermes_units() which is an explicit
allowlist of hermes.service only — profile units never match.
Platform-gated: only prints on systemd hosts (the rename is Linux-only).
Non-blocking: just prints, never prompts, so gateway-spawned
hermes update --gateway runs aren't affected.
* fix(gateway): detect legacy hermes.service units from pre-rename installs
Older Hermes installs used a different service name (hermes.service) before
the rename to hermes-gateway.service. When both units remain installed, they
fight over the same bot token — after PR #5646's signal-recovery change,
this manifests as a 30-second SIGTERM flap loop between the two services.
Detection is an explicit allowlist (no globbing) plus an ExecStart content
check, so profile units (hermes-gateway-<profile>.service) and unrelated
third-party services named 'hermes' are never matched.
Wired into systemd_install, systemd_status, gateway_setup wizard, and the
main hermes setup flow — anywhere we already warn about scope conflicts now
also warns about legacy units.
* feat(gateway): add migrate-legacy command + install-time removal prompt
- New hermes_cli.gateway.remove_legacy_hermes_units() removes legacy
unit files with stop → disable → unlink → daemon-reload. Handles user
and system scopes separately; system scope returns path list when not
running as root so the caller can tell the user to re-run with sudo.
- New 'hermes gateway migrate-legacy' subcommand (with --dry-run and -y)
routes to remove_legacy_hermes_units via gateway_command dispatch.
- systemd_install now offers to remove legacy units BEFORE installing
the new hermes-gateway.service, preventing the SIGTERM flap loop that
hits users who still have pre-rename hermes.service around.
Profile units (hermes-gateway-<profile>.service) remain untouched in
all paths — the legacy allowlist is explicit (_LEGACY_SERVICE_NAMES)
and the ExecStart content check further narrows matches.
* fix(gateway): mark --replace SIGTERM as planned so target exits 0
PR #5646 made SIGTERM exit the gateway with code 1 so systemd's
Restart=on-failure revives it after unexpected kills. But when a user has
two gateway units fighting for the same bot token (e.g. legacy
hermes.service + hermes-gateway.service from a pre-rename install), the
--replace takeover itself becomes the 'unexpected' SIGTERM — the loser
exits 1, systemd revives it 30s later, and the cycle flaps indefinitely.
Before calling terminate_pid(), --replace now writes a short-lived marker
file naming the target PID + start_time. The target's shutdown_signal_handler
consumes the marker and, when it names this process, leaves
_signal_initiated_shutdown=False so the final exit code stays 0.
Staleness defences:
- PID + start_time combo prevents PID reuse matching an old marker
- Marker older than 60s is treated as stale and discarded
- Marker is unlinked on first read even if it doesn't match this process
- Replacer clears the marker post-loop + on permission-denied give-up
Before: aggregator users (OpenRouter / Nous Portal) running 'auto'
routing for auxiliary tasks — compression, vision, web extraction,
session search, etc. — got routed to a cheap provider-side default
model (Gemini Flash). Non-aggregator users already got their main
model. Behavior was inconsistent and surprising — users picked
Claude / GPT / their preferred model, but side tasks ran on
Gemini Flash.
After: 'auto' means "use my main chat model" for every user,
regardless of provider type. Only when the main provider has no
working client does the fallback chain run (OpenRouter → Nous →
custom → Codex → API-key providers). Explicit per-task overrides
in config.yaml (auxiliary.<task>.provider / .model) still win —
they are a hard constraint, not subject to the auto policy.
Vision auto-detection follows the same policy: try main provider +
main model first (with _PROVIDER_VISION_MODELS overrides preserved
for providers like xiaomi and zai that ship a dedicated multimodal
model distinct from their chat model). Aggregator strict vision
backends are fallbacks, not the primary path.
Changes:
- agent/auxiliary_client.py: _resolve_auto() drops the
`_AGGREGATOR_PROVIDERS` guard. resolve_vision_provider_client()
auto branch unifies aggregator and exotic-provider paths —
everyone goes through resolve_provider_client() with main_model.
Dead _AGGREGATOR_PROVIDERS constant removed (was only used by
the guard we just removed).
- hermes_cli/main.py: aux config menu copy updated to reflect
the new semantics ("'auto' means 'use my main model'").
- tests/agent/test_auxiliary_main_first.py: 12 regression tests
covering OpenRouter/Nous/DeepSeek main paths, runtime-override
wins, explicit-config wins, vision override preservation for
exotic providers, and fallback-chain activation when the main
provider has no working client.

Previously users had to hand-edit config.yaml to route individual auxiliary
tasks (vision, compression, web_extract, etc.) to a specific provider+model.
Add a first-class picker reachable from the bottom of the existing `hermes
model` provider list.
Flow:
hermes model
→ Configure auxiliary models...
→ <task picker: 9 tasks, shows current setting inline>
→ <provider picker: authenticated providers + auto + custom>
→ <model picker: curated list + live pricing>
The aux picker does NOT re-run credential/OAuth setup; users authenticate
providers through the normal `hermes model` flow, then route aux tasks to
them here. `list_authenticated_providers()` gates the list to providers
the user has configured.
Also:
- 'Cancel' entry relabeled 'Leave unchanged' (sentinel still 'cancel'
internally, so dispatch logic is unchanged)
- 'Reset all to auto' entry to bulk-clear aux overrides; preserves
user-tuned timeout / download_timeout values
- Adds `title_generation` task to DEFAULT_CONFIG.auxiliary — the task
was called from agent/title_generator.py but was missing from defaults,
so config-backed timeout overrides never worked for it

Follow-up on the native NVIDIA NIM provider salvage. The original PR wired
PROVIDER_REGISTRY + HERMES_OVERLAYS correctly but missed several touchpoints
required for full parity with other OpenAI-compatible providers (xai,
huggingface, deepseek, zai).
Gaps closed:
- hermes_cli/main.py:
- Add 'nvidia' to the _model_flow_api_key_provider dispatch tuple so
selecting 'NVIDIA NIM' in `hermes model` actually runs the api-key
provider flow (previously fell through silently).
- Add 'nvidia' to `hermes chat --provider` argparse choices so the
documented test command (`hermes chat --provider nvidia --model ...`)
parses successfully.
- hermes_cli/config.py: Register NVIDIA_API_KEY and NVIDIA_BASE_URL in
OPTIONAL_ENV_VARS so setup wizard can prompt for them and they're
auto-added to the subprocess env blocklist.
- hermes_cli/doctor.py: Add NVIDIA NIM row to `_apikey_providers` so
`hermes doctor` probes https://integrate.api.nvidia.com/v1/models.
- hermes_cli/dump.py: Add NVIDIA_API_KEY → 'nvidia' mapping for
`hermes dump` credential masking.
- tests/tools/test_local_env_blocklist.py: Extend registry_vars fixture
with NVIDIA_API_KEY to verify it's blocked from leaking into subprocesses.
- agent/model_metadata.py: Add 'nemotron' → 131072 context-length entry
so all Nemotron variants get 128K context via substring match (rather
than falling back to MINIMUM_CONTEXT_LENGTH).
- hermes_cli/models.py: Fix hallucinated model ID
'nvidia/nemotron-3-nano-8b-a4b' → 'nvidia/nemotron-3-nano-30b-a3b'
(verified against live integrate.api.nvidia.com/v1/models catalog).
Expand curated list from 5 to 9 agentic models mapping to OpenRouter
defaults per provider-guide convention: add qwen3.5-397b-a17b,
deepseek-v3.2, llama-3.3-nemotron-super-49b-v1.5, gpt-oss-120b.
- cli-config.yaml.example: Document 'nvidia' provider option.
- scripts/release.py: Map asurla@nvidia.com → anniesurla in AUTHOR_MAP
for CI attribution.
E2E verified: `hermes chat --provider nvidia ...` now reaches NVIDIA's
endpoint (returns 401 with bogus key instead of argparse error);
`hermes doctor` detects NVIDIA NIM when NVIDIA_API_KEY is set.
Move moonshotai/kimi-k2.5 to position #1 in every model picker list:
- OPENROUTER_MODELS (with 'recommended' tag)
- _PROVIDER_MODELS: nous, kimi-coding, opencode-zen, opencode-go, alibaba, huggingface
- _model_flow_kimi() Coding Plan model list in main.py
kimi-coding-cn and moonshot lists already had kimi-k2.5 first.
When a user edits a bundled skill, sync flags it as user_modified and
skips it forever. The problem: if the user later tries to undo the edit
by copying the current bundled version back into ~/.hermes/skills/, the
manifest still holds the old origin hash from the last successful
sync, so the fresh bundled hash still doesn't match and the skill stays
stuck as user_modified.
Adds an escape hatch for this case.
hermes skills reset <name>
Drops the skill's entry from ~/.hermes/skills/.bundled_manifest and
re-baselines against the user's current copy. Future 'hermes update'
runs accept upstream changes again. Non-destructive.
hermes skills reset <name> --restore
Also deletes the user's copy and re-copies the bundled version.
Use when you want the pristine upstream skill back.
Also available as /skills reset in chat.
- tools/skills_sync.py: new reset_bundled_skill(name, restore=False)
- hermes_cli/skills_hub.py: do_reset() + wired into skills_command and
handle_skills_slash; added to the slash /skills help panel
- hermes_cli/main.py: argparse entry for 'hermes skills reset'
- tests/tools/test_skills_sync.py: 5 new tests covering the stuck-flag
repro, --restore, unknown-skill error, upstream-removed-skill, and
no-op on already-clean state
- website/docs/user-guide/features/skills.md: new 'Bundled skill updates'
section explaining the origin-hash mechanic + reset usage
* feat(mcp-oauth): scaffold MCPOAuthManager
Central manager for per-server MCP OAuth state. Provides
get_or_build_provider (cached), remove (evicts cache + deletes
disk), invalidate_if_disk_changed (mtime watch, core fix for
external-refresh workflow), and handle_401 (dedup'd recovery).
No behavior change yet — existing call sites still use
build_oauth_auth directly. Task 1 of 8 in the MCP OAuth
consolidation (fixes Cthulhu's BetterStack reliability issues).
* feat(mcp-oauth): add HermesMCPOAuthProvider with pre-flow disk watch
Subclasses the MCP SDK's OAuthClientProvider to inject a disk
mtime check before every async_auth_flow, via the central
manager. When a subclass instance is used, external token
refreshes (cron, another CLI instance) are picked up before
the next API call.
Still dead code: the manager's _build_provider still delegates
to build_oauth_auth and returns the plain OAuthClientProvider.
Task 4 wires this subclass in. Task 2 of 8.
* refactor(mcp-oauth): extract build_oauth_auth helpers
Decomposes build_oauth_auth into _configure_callback_port,
_build_client_metadata, _maybe_preregister_client, and
_parse_base_url. Public API preserved. These helpers let
MCPOAuthManager._build_provider reuse the same logic in Task 4
instead of duplicating the construction dance.
Also updates the SDK version hint in the warning from 1.10.0 to
1.26.0 (which is what we actually require for the OAuth types
used here). Task 3 of 8.
* feat(mcp-oauth): manager now builds HermesMCPOAuthProvider directly
_build_provider constructs the disk-watching subclass using the
helpers from Task 3, instead of delegating to the plain
build_oauth_auth factory. Any consumer using the manager now gets
pre-flow disk-freshness checks automatically.
build_oauth_auth is preserved as the public API for backwards
compatibility. The code path is now:
MCPOAuthManager.get_or_build_provider ->
_build_provider ->
_configure_callback_port
_build_client_metadata
_maybe_preregister_client
_parse_base_url
HermesMCPOAuthProvider(...)
Task 4 of 8.
* feat(mcp): wire OAuth manager + add _reconnect_event
MCPServerTask gains _reconnect_event alongside _shutdown_event.
When set, _run_http / _run_stdio exit their async-with blocks
cleanly (no exception), and the outer run() loop re-enters the
transport to rebuild the MCP session with fresh credentials.
This is the recovery path for OAuth failures that the SDK's
in-place httpx.Auth cannot handle (e.g. cron externally consumed
the refresh_token, or server-side session invalidation).
_run_http now asks MCPOAuthManager for the OAuth provider
instead of calling build_oauth_auth directly. Config-time,
runtime, and reconnect paths all share one provider instance
with pre-flow disk-watch active.
shutdown() defensively sets both events so there is no race
between reconnect and shutdown signalling.
Task 5 of 8.
* feat(mcp): detect auth failures in tool handlers, trigger reconnect
All 5 MCP tool handlers (tool call, list_resources, read_resource,
list_prompts, get_prompt) now detect auth failures and route
through MCPOAuthManager.handle_401:
1. If the manager says recovery is viable (disk has fresh tokens,
or SDK can refresh in-place), signal MCPServerTask._reconnect_event
to tear down and rebuild the MCP session with fresh credentials,
then retry the tool call once.
2. If no recovery path exists, return a structured needs_reauth
JSON error so the model stops hallucinating manual refresh
attempts (the 'let me curl the token endpoint' loop Cthulhu
pasted from Discord).
_is_auth_error catches OAuthFlowError, OAuthTokenError,
OAuthNonInteractiveError, and httpx.HTTPStatusError(401). Non-auth
exceptions still surface via the generic error path unchanged.
Task 6 of 8.
* feat(mcp-cli): route add/remove through manager, add 'hermes mcp login'
cmd_mcp_add and cmd_mcp_remove now go through MCPOAuthManager
instead of calling build_oauth_auth / remove_oauth_tokens
directly. This means CLI config-time state and runtime MCP
session state are backed by the same provider cache — removing
a server evicts the live provider, adding a server populates
the same cache the MCP session will read from.
New 'hermes mcp login <name>' command:
- Wipes both the on-disk tokens file and the in-memory
MCPOAuthManager cache
- Triggers a fresh OAuth browser flow via the existing probe
path
- Intended target for the needs_reauth error Task 6 returns
to the model
Task 7 of 8.
* test(mcp-oauth): end-to-end integration tests
Five new tests exercising the full consolidation with real file
I/O and real imports (no transport mocks):
1. external_refresh_picked_up_without_restart — Cthulhu's cron
workflow. External process writes fresh tokens to disk;
on the next auth flow the manager's mtime-watch flips
_initialized and the SDK re-reads from storage.
2. handle_401_deduplicates_concurrent_callers — 10 concurrent
handlers for the same failed token fire exactly ONE recovery
attempt (thundering-herd protection).
3. handle_401_returns_false_when_no_provider — defensive path
for unknown servers.
4. invalidate_if_disk_changed_handles_missing_file — pre-auth
state returns False cleanly.
5. provider_is_reused_across_reconnects — cache stickiness so
reconnects preserve the disk-watch baseline mtime.
Task 8 of 8 — consolidation complete.
"Ink" is the React reconciler — implementation detail, not branding.
Consistent naming: the classic CLI is the CLI, the new one is the TUI.
Updated docs: user-guide/tui.md, user-guide/cli.md cross-link, quickstart,
cli-commands reference, environment-variables reference.
Updated code: main.py --tui help text, server.py user-visible setup
error, AGENTS.md "TUI Architecture" section.
Kept "Ink" only where it is literally the library (hermes-ink internal
source comments, AGENTS.md tree note flagging ui-tui/ as a React/Ink dir).
All 61 TUI-related tests green across 3 consecutive xdist runs.
tests/tui_gateway/test_protocol.py:
- rename `get_messages` → `get_messages_as_conversation` on mock DB (method
was renamed in the real backend, test was still stubbing the old name)
- update tool-message shape expectation: `{role, name, context}` matches
current `_history_to_messages` output, not the legacy `{role, text}`
tests/hermes_cli/test_tui_resume_flow.py:
- `cmd_chat` grew a first-run provider-gate that bailed to "Run: hermes
setup" before `_launch_tui` was ever reached; 3 tests stubbed
`_resolve_last_session` + `_launch_tui` but not the gate
- factored a `main_mod` fixture that stubs `_has_any_provider_configured`,
reused by all three tests
tests/test_tui_gateway_server.py:
- `test_config_set_personality_resets_history_and_returns_info` was flaky
under xdist because the real `_write_config_key` touches
`~/.hermes/config.yaml`, racing with any other worker that writes
config. Stub it in the test.
Replace the HERMES_ENABLE_NOUS_MANAGED_TOOLS env-var feature flag with
subscription-based detection. The Tool Gateway is now available to any
paid Nous subscriber without needing a hidden env var.
Core changes:
- managed_nous_tools_enabled() checks get_nous_auth_status() +
check_nous_free_tier() instead of an env var
- New use_gateway config flag per tool section (web, tts, browser,
image_gen) records explicit user opt-in and overrides direct API
keys at runtime
- New prefers_gateway(section) shared helper in tool_backend_helpers.py
used by all 4 tool runtimes (web, tts, image gen, browser)
UX flow:
- hermes model: after Nous login/model selection, shows a curses
prompt listing all gateway-eligible tools with current status.
User chooses to enable all, enable only unconfigured tools, or skip.
Defaults to Enable for new users, Skip when direct keys exist.
- hermes tools: provider selection now manages use_gateway flag —
selecting Nous Subscription sets it, selecting any other provider
clears it
- hermes status: renamed section to Nous Tool Gateway, added
free-tier upgrade nudge for logged-in free users
- curses_radiolist: new description parameter for multi-line context
that survives the screen clear
Runtime behavior:
- Each tool runtime (web_tools, tts_tool, image_generation_tool,
browser_use) checks prefers_gateway() before falling back to
direct env-var credentials
- get_nous_subscription_features() respects use_gateway flags,
suppressing direct credential detection when the user opted in
Removed:
- HERMES_ENABLE_NOUS_MANAGED_TOOLS env var and all references
- apply_nous_provider_defaults() silent TTS auto-set
- get_nous_subscription_explainer_lines() static text
- Override env var warnings (use_gateway handles this properly now)
config.yaml terminal.cwd is now the single source of truth for working
directory. MESSAGING_CWD and TERMINAL_CWD in .env are deprecated with a
migration warning.
Changes:
1. config.py: Remove MESSAGING_CWD from OPTIONAL_ENV_VARS (setup wizard
no longer prompts for it). Add warn_deprecated_cwd_env_vars() that
prints a migration hint when deprecated env vars are detected.
2. gateway/run.py: Replace all MESSAGING_CWD reads with TERMINAL_CWD
(which is bridged from config.yaml terminal.cwd). MESSAGING_CWD is
still accepted as a backward-compat fallback with deprecation warning.
Config bridge skips cwd placeholder values so they don't clobber
the resolved TERMINAL_CWD.
3. cli.py: Guard against lazy-import clobbering — when cli.py is
imported lazily during gateway runtime (via delegate_tool), don't
let load_cli_config() overwrite an already-resolved TERMINAL_CWD
with os.getcwd() of the service's working directory. (#10817)
4. hermes_cli/main.py: Add 'hermes memory reset' command with
--target all/memory/user and --yes flags. Profile-scoped via
HERMES_HOME.
Migration path for users with .env settings:
Remove MESSAGING_CWD / TERMINAL_CWD from .env
Add to config.yaml:
terminal:
cwd: /your/project/path
Addresses: #10225, #4672, #10817, #7663
When a user enters a local model server URL (Ollama, vLLM, llama.cpp)
without a /v1 suffix during 'hermes model' custom endpoint setup,
prompt them to add it. Most OpenAI-compatible local servers require
/v1 in the base URL for chat completions to work.
Three independent fixes batched together:
1. hermes auth add crashes on non-interactive stdin (#10468)
input() for the label prompt was called without checking isatty().
In scripted/CI environments this raised EOFError. Fix: check
sys.stdin.isatty() and fall back to the computed default label.
2. Subcommand help prints twice (#10230)
'hermes dashboard -h' printed help text twice because the
SystemExit(0) from argparse was caught by the fallback retry
logic, which re-parsed and printed help again. Fix: re-raise
SystemExit with code 0 (help/version) immediately.
3. Duplicate entries in /model picker (#10526, #9545)
- Kimi showed 2x because kimi-coding and kimi-coding-cn both
mapped to the same models.dev ID. Fix: track seen mdev_ids
and skip aliases.
- Providers could show 2-3x from case-variant slugs across the
four loading paths. Fix: normalize all seen_slugs membership
checks and insertions to lowercase.
Closes#10468, #10230, #10526, #9545
- Pastes uploaded by /debug now auto-delete after 1 hour via a detached
background process that sends DELETE to paste.rs
- CLI: shows privacy notice listing what data will be uploaded
- Gateway: only uploads summary report (system info + log tails), NOT
full log files containing conversation content
- Added 'hermes debug delete <url>' for immediate manual deletion
- 16 new tests covering auto-delete scheduling, paste deletion, privacy
notices, and the delete subcommand
Addresses user privacy concern where /debug uploaded full conversation
logs to a public paste service with no warning or expiry.
On some Python versions, argparse fails to route subcommand tokens when
the parent parser has nargs='?' optional arguments (--continue). The
symptom: 'hermes model' produces 'unrecognized arguments: model' even
though 'model' is a registered subcommand.
Fix: when argv contains a token matching a known subcommand, set
subparsers.required=True to force deterministic routing. If that fails
(e.g. 'hermes -c model' where 'model' is consumed as the session name
for --continue), fall back to the default optional-subparsers behaviour.
Adds 13 tests covering all key argument combinations.
Reported via user screenshot showing the exact error on an installed
version with the model subcommand listed in usage but rejected at parse
time.
- gateway start --all: kills all stale gateway processes across all
profiles before starting the current profile's service
- gateway restart --all: stops all gateway processes across all
profiles, then starts the current profile's service fresh
- gateway stop --all: already existed, unchanged
The --all flag was only available on 'stop' but not on 'start' or
'restart', causing 'unrecognized arguments' errors for users.
Three fixes for gateway lifecycle stability:
1. Notify active sessions before shutdown (#new)
When the gateway receives SIGTERM or /restart, it now sends a
notification to every chat with an active agent BEFORE starting
the drain. Users see:
- Shutdown: 'Gateway shutting down — your task will be interrupted.'
- Restart: 'Gateway restarting — use /retry after restart to continue.'
Deduplicates per-chat so group sessions with multiple users get
one notification. Best-effort: send failures are logged and swallowed.
2. Skip .clean_shutdown marker when drain timed out
Previously, a graceful SIGTERM always wrote .clean_shutdown, even if
agents were force-interrupted when the drain timed out. This meant
the next startup skipped session suspension, leaving interrupted
sessions in a broken state (trailing tool response, no final message).
Now the marker is only written if the drain completed without timeout,
so interrupted sessions get properly suspended on next startup.
3. Post-restart health check for hermes update (#6631)
cmd_update() now verifies the gateway actually survived after
systemctl restart (sleep 3s + is-active check). If the service
crashed immediately, it retries once. If still dead, prints
actionable diagnostics (journalctl command, manual restart hint).
Also closes#8104 — already fixed on main (the /restart handler
correctly detects systemd via INVOCATION_ID and uses via_service=True).
Test plan:
- 6 new tests for shutdown notifications (dedup, restart vs shutdown
messaging, sentinel filtering, send failure resilience)
- Existing restart drain + update tests pass (47 total)
Addresses responsible disclosure from FuzzMind Security Lab (CVE pending).
The web dashboard API server had 36 endpoints, of which only 5 checked
the session token. The token itself was served from an unauthenticated
GET /api/auth/session-token endpoint, rendering the protection circular.
When bound to 0.0.0.0 (--host flag), all API keys, config, and cron
management were accessible to any machine on the network.
Changes:
- Add auth middleware requiring session token on ALL /api/ routes except
a small public whitelist (status, config/defaults, config/schema,
model/info)
- Remove GET /api/auth/session-token endpoint entirely; inject the token
into index.html via a <script> tag at serve time instead
- Replace all inline token comparisons (!=) with hmac.compare_digest()
to prevent timing side-channel attacks
- Block non-localhost binding by default; require --insecure flag to
override (with warning log)
- Update frontend fetchJSON() to send Authorization header on all
requests using the injected window.__HERMES_SESSION_TOKEN__

The dynamic parser walker from the contributor's commit lost the profile
name tab-completion that existed in the old static generators. This adds
it back for all three shells:
- Bash: _hermes_profiles() helper, -p/--profile completion, profile
action→name completion (use/delete/show/alias/rename/export)
- Zsh: _hermes_profiles() function, -p/--profile argument spec, profile
action case with name completion
- Fish: __hermes_profiles function, -s p -l profile flag, profile action
completions
Also removes the dead fallback path in cmd_completion() that imported
the old static generators from profiles.py (parser is always available
via the lambda wiring) and adds 11 regression-prevention tests for
profile completion.
Replaces the hardcoded completion stubs in profiles.py with a dynamic
generator that walks the live argparse parser tree at runtime.
- New hermes_cli/completion.py: _walk() recursively extracts all
subcommands and flags; generate_bash/zsh/fish() produce complete
scripts with nested subcommand support
- cmd_completion now accepts the parser via closure so completions
always reflect the actual registered commands (including plugin-
registered ones like honcho)
- completion subcommand now accepts bash | zsh | fish (fish requested
in issue comments)
- Fix _SUBCOMMANDS set: add honcho, claw, plugins, acp, webhook,
memory, dump, debug, backup, import, completion, logs so that
multi-word session names after -c/-r are not broken by these commands
- Add tests/hermes_cli/test_completion.py: 17 tests covering parser
extraction, alias deduplication, bash/zsh/fish output content,
bash syntax validation, fish syntax validation, and subcommand
drift prevention
Tested on Linux (Arch). bash and fish completion verified live.
zsh script passes syntax check (zsh not installed on test machine).

During custom endpoint setup, users are now asked for a display name
with the auto-generated name as the default. Typing 'Ollama' or
'LM Studio' replaces the generic 'Local (localhost:11434)' in the
provider menu.
Extracts _auto_provider_name() for reuse and adds a name= parameter
to _save_custom_provider() so the caller can pass through the
user-chosen label.
Remove the two-tier (top/extended) provider picker that hid most
providers behind a 'More providers...' submenu. All providers now
appear in a single flat list.
- Remove tier field from ProviderEntry namedtuple
- Remove tier values from all CANONICAL_PROVIDERS entries
- Flatten the hermes model picker (no more 'More...' submenu)
- Move 'Custom endpoint' to the bottom of the main list
Adds Arcee AI as a standard direct provider (ARCEEAI_API_KEY) with
Trinity models: trinity-large-thinking, trinity-large-preview, trinity-mini.
Standard OpenAI-compatible provider checklist: auth.py, config.py,
models.py, main.py, providers.py, doctor.py, model_normalize.py,
model_metadata.py, setup.py, trajectory_compressor.py.
Based on PR #9274 by arthurbr11, simplified to a standard direct
provider without dual-endpoint OpenRouter routing.
Three separate hardcoded provider lists (/model, /provider, hermes model)
diverged over time, causing providers to be missing from some commands.
- Create CANONICAL_PROVIDERS in hermes_cli/models.py as the single source
of truth for all provider identity, labels, and TUI ordering
- Derive _PROVIDER_LABELS and list_available_providers() from canonical list
- Add step 2b in list_authenticated_providers() to cross-check canonical
list — catches providers with credentials that weren't found via
PROVIDER_TO_MODELS_DEV or HERMES_OVERLAYS mappings
- Derive hermes model TUI provider menus from canonical list
- Add deepseek and xai as first-class providers (were missing from TUI)
- Add grok/x-ai/x.ai aliases for xai provider
Fixes: /model command not showing all providers that hermes model shows
Cherry-picked from PR #7637 by hcshen0111.
Adds kimi-coding-cn provider with dedicated KIMI_CN_API_KEY env var
and api.moonshot.cn/v1 endpoint for China-region Moonshot users.
The v11→v12 migration converts custom_providers (list) into providers
(dict), then deletes the list. But all runtime resolvers read from
custom_providers — after migration, named custom endpoints silently stop
resolving and fallback chains fail with AuthError.
Add get_compatible_custom_providers() that reads from both config schemas
(legacy custom_providers list + v12+ providers dict), normalizes entries,
deduplicates, and returns a unified list. Update ALL consumers:
- hermes_cli/runtime_provider.py: _get_named_custom_provider() + key_env
- hermes_cli/auth_commands.py: credential pool provider names
- hermes_cli/main.py: model picker + _model_flow_named_custom()
- agent/auxiliary_client.py: key_env + custom_entry model fallback
- agent/credential_pool.py: _iter_custom_providers()
- cli.py + gateway/run.py: /model switch custom_providers passthrough
- run_agent.py + gateway/run.py: per-model context_length lookup
Also: use config.pop() instead of del for safer migration, fix stale
_config_version assertions in tests, add pool mock to codex test.

Closes#8776, salvaged from PR #8814
Three changes consolidated into the existing backup system:
1. Fix: hermes backup now uses sqlite3.Connection.backup() for .db files
instead of raw file copy. Raw copy of a WAL-mode database can produce
a corrupted backup — the backup() API handles this correctly.
2. hermes backup --quick: fast snapshot of just critical state files
(config.yaml, state.db, .env, auth.json, cron/jobs.json, etc.)
stored in ~/.hermes/state-snapshots/. Auto-prunes to 20 snapshots.
3. /snapshot slash command (alias /snap): in-session interface for
quick state snapshots. create/list/restore/prune subcommands.
Restore by ID or number. Powered by the same backup module.
No new modules — everything lives in hermes_cli/backup.py alongside
the existing full backup/import code.
No hooks in run_agent.py — purely on-demand, zero runtime overhead.
Closes the use case from PRs #8406 and #7813 with ~200 lines of new
logic instead of a 1090-line content-addressed storage engine.
* feat: web UI dashboard for managing Hermes Agent (salvage of #8204/#7621)
Adds an embedded web UI dashboard accessible via `hermes web`:
- Status page: agent version, active sessions, gateway status, connected platforms
- Config editor: schema-driven form with tabbed categories, import/export, reset
- API Keys page: set, clear, and view redacted values with category grouping
- Sessions, Skills, Cron, Logs, and Analytics pages
Backend:
- hermes_cli/web_server.py: FastAPI server with REST endpoints
- hermes_cli/config.py: reload_env() utility for hot-reloading .env
- hermes_cli/main.py: `hermes web` subcommand (--port, --host, --no-open)
- cli.py / commands.py: /reload slash command for .env hot-reload
- pyproject.toml: [web] optional dependency extra (fastapi + uvicorn)
- Both update paths (git + zip) auto-build web frontend when npm available
Frontend:
- Vite + React + TypeScript + Tailwind v4 SPA in web/
- shadcn/ui-style components, Nous design language
- Auto-refresh status page, toast notifications, masked password inputs
Security:
- Path traversal guard (resolve().is_relative_to()) on SPA file serving
- CORS localhost-only via allow_origin_regex
- Generic error messages (no internal leak), SessionDB handles closed properly
Tests: 47 tests covering reload_env, redact_key, API endpoints, schema
generation, path traversal, category merging, internal key stripping,
and full config round-trip.
Original work by @austinpickett (PR #1813), salvaged by @kshitijk4poor
(PR #7621 → #8204), re-salvaged onto current main with stale-branch
regressions removed.
* fix(web): clean up status page cards, always rebuild on `hermes web`
- Remove config version migration alert banner from status page
- Remove config version card (internal noise, not surfaced in TUI)
- Reorder status cards: Agent → Gateway → Active Sessions (3-col grid)
- `hermes web` now always rebuilds from source before serving,
preventing stale web_dist when editing frontend files
* feat(web): full-text search across session messages
- Add GET /api/sessions/search endpoint backed by FTS5
- Auto-append prefix wildcards so partial words match (e.g. 'nimb' → 'nimby')
- Debounced search (300ms) with spinner in the search icon slot
- Search results show FTS5 snippets with highlighted match delimiters
- Expanding a search hit auto-scrolls to the first matching message
- Matching messages get a warning ring + 'match' badge
- Inline term highlighting within Markdown (text, bold, italic, headings, lists)
- Clear button (x) on search input for quick reset

* feat: add `hermes debug share` — upload debug report to pastebin
Adds a new `hermes debug share` command that collects system info
(via hermes dump), recent logs (agent.log, errors.log, gateway.log),
and uploads the combined report to a paste service (paste.rs primary,
dpaste.com fallback). Returns a shareable URL for support.
Options:
--lines N Number of log lines per file (default: 200)
--expire N Paste expiry in days (default: 7, dpaste.com only)
--local Print report locally without uploading
Files:
hermes_cli/debug.py - New module: paste upload + report collection
hermes_cli/main.py - Wire cmd_debug + argparse subparser
tests/hermes_cli/test_debug.py - 19 tests covering upload, collection, CLI
* feat: upload full agent.log and gateway.log as separate pastes
hermes debug share now uploads up to 3 pastes:
1. Summary report (system info + log tails) — always
2. Full agent.log (last ~500KB) — if file exists
3. Full gateway.log (last ~500KB) — if file exists
Each paste uploads independently; log upload failures are noted
but don't block the main report. Output shows all links aligned:
Report https://paste.rs/abc
agent.log https://paste.rs/def
gateway.log https://paste.rs/ghi
Also adds _read_full_log() with size-capped tail reading to stay
within paste service limits (~512KB per file).
* feat: prepend hermes dump to each log paste for self-contained context
Each paste (agent.log, gateway.log) now starts with the hermes dump
output so clicking any single link gives full system context without
needing to cross-reference the summary report.
Refactored dump capture into _capture_dump() — called once and
reused across the summary report and each log paste.
* fix: fall back to .1 rotated log when primary log is missing or empty
When gateway.log (or agent.log) doesn't exist or is empty, the debug
share now checks for the .1 rotation file. This is common — the
gateway rotates logs and the primary file may not exist yet.
Extracted _resolve_log_path() to centralize the fallback logic for
both _read_log_tail() and _read_full_log().
* chore: remove unused display_hermes_home import
Fresh profiles (created without --clone) now:
- Auto-seed a default SOUL.md immediately, so users have a file to
customize right away instead of discovering it only after first use
- Print a clear warning that the profile has no API keys and will
inherit from the shell environment unless configured separately
- Show the SOUL.md path for personality customization
Previously, fresh profiles started with no SOUL.md (only seeded on
first use via ensure_hermes_home), no mention of credential isolation,
and no guidance about customizing personality. Users reported confusion
about profiles using the wrong model/plan tokens and SOUL.md not
being read — both traced to operational gaps in the creation UX.
Closes#8093 (investigated: code correctly loads SOUL.md from profile
HERMES_HOME; issue was operational, not a code bug).
When /update runs via Telegram, hermes update --gateway is spawned inside
the gateway's systemd cgroup. The update process itself calls
systemctl restart hermes-gateway, which tears down the cgroup with
KillMode=mixed — SIGKILL to all remaining processes. The wrapping bash
shell is killed before it can execute the exit-code epilogue, so
.update_exit_code is never created. The new gateway's update watcher
then polls for 30 minutes and sends a spurious timeout message.
Fix: write .update_exit_code from Python inside cmd_update() immediately
after the git pull + pip install succeed ("Update complete!"), before
attempting the gateway restart. The shell epilogue still writes it too
(idempotent overwrite), but now the marker exists even when the process
is killed mid-restart.
Reject non-URL values (e.g. shell commands typed by mistake) in the
base URL prompt during provider setup. Previously any string was saved
as-is to .env, breaking connectivity when the garbage value was used
as the API endpoint.
Adds http:// / https:// prefix check with a clear error message.
The custom-endpoint flow already had this validation (line 1620);
this brings the generic API-key provider flow to parity.
Triggered by a user support case where 'nano ~/.hermes/.env' was
accidentally entered as GLM_BASE_URL during Z.AI setup.
- Add openai/openai-codex -> openai mapping to PROVIDER_TO_MODELS_DEV
so context-length lookups use models.dev data instead of 128k fallback.
Fixes#8161.
- Set api_mode from custom_providers entry when switching via hermes model,
and clear stale api_mode when the entry has none. Also extract api_mode
in _named_custom_provider_map(). Fixes#8181.
- Convert OpenAI image_url content blocks to Anthropic image blocks when
the endpoint is Anthropic-compatible (MiniMax, MiniMax-CN, or any URL
containing /anthropic). Fixes#8147.
On servers with broken or unreachable IPv6, Python's socket.getaddrinfo
returns AAAA records first. urllib/httpx/requests all try IPv6 connections
first and hang for the full TCP timeout before falling back to IPv4. This
affects web_extract, web_search, the OpenAI SDK, and all HTTP tools.
Adds network.force_ipv4 config option (default: false) that monkey-patches
socket.getaddrinfo to resolve as AF_INET when the caller didn't specify a
family. Falls back to full resolution if no A record exists, so pure-IPv6
hosts still work.
Applied early at all three entry points (CLI, gateway, cron scheduler)
before any HTTP clients are created.
Reported by user @29n — Chinese Ubuntu server with unreachable IPv6 causing
timeouts on lobste.rs and other IPv6-enabled sites while Google/GitHub
worked fine (IPv4-only resolution).
* feat: add `hermes backup` and `hermes import` commands
hermes backup — creates a zip of ~/.hermes/ (config, skills, sessions,
profiles, memories, skins, cron jobs, etc.) excluding the hermes-agent
codebase, __pycache__, and runtime PID files. Defaults to
~/hermes-backup-<timestamp>.zip, customizable with -o.
hermes import <zipfile> — restores from a backup zip, validating it
looks like a hermes backup before extracting. Handles .hermes/ prefix
stripping, path traversal protection, and confirmation prompts (skip
with --force).
29 tests covering exclusion rules, backup creation, import validation,
prefix detection, path traversal blocking, confirmation flow, and a
full round-trip test.
* test: improve backup/import coverage to 97%
Add 17 additional tests covering:
- _format_size helper (bytes through terabytes)
- Nonexistent hermes home error exit
- Output path is a directory (auto-names inside it)
- Output without .zip suffix (auto-appends)
- Empty hermes home (all files excluded)
- Permission errors during backup and import
- Output zip inside hermes root (skips itself)
- Not-a-zip file rejection
- EOFError and KeyboardInterrupt during confirmation
- 500+ file progress display
- Directory-only zip prefix detection
Remove dead code branch in _detect_prefix (unreachable guard).
* feat: auto-restore profile wrapper scripts on import
After extracting backup files, hermes import now scans profiles/ for
subdirectories with config.yaml or .env and recreates the ~/.local/bin
wrapper scripts so profile aliases (e.g. 'coder chat') work immediately.
Also prints guidance for re-installing gateway services per profile.
Handles edge cases:
- Skips profile dirs without config (not real profiles)
- Skips aliases that collide with existing commands
- Gracefully degrades if hermes_cli.profiles isn't available (fresh install)
- Shows PATH hint if ~/.local/bin isn't in PATH
3 new profile restoration tests (49 total).
* feat: component-separated logging with session context and filtering
Phase 1 — Gateway log isolation:
- gateway.log now only receives records from gateway.* loggers
(platform adapters, session management, slash commands, delivery)
- agent.log remains the catch-all (all components)
- errors.log remains WARNING+ catch-all
- Moved gateway.log handler creation from gateway/run.py into
hermes_logging.setup_logging(mode='gateway') with _ComponentFilter
Phase 2 — Session ID injection:
- Added set_session_context(session_id) / clear_session_context() API
using threading.local() for per-thread session tracking
- _SessionFilter enriches every log record with session_tag attribute
- Log format: '2026-04-11 10:23:45 INFO [session_id] logger.name: msg'
- Session context set at start of run_conversation() in run_agent.py
- Thread-isolated: gateway conversations on different threads don't leak
Phase 3 — Component filtering in hermes logs:
- Added --component flag: hermes logs --component gateway|agent|tools|cli|cron
- COMPONENT_PREFIXES maps component names to logger name prefixes
- Works with all existing filters (--level, --session, --since, -f)
- Logger name extraction handles both old and new log formats
Files changed:
- hermes_logging.py: _SessionFilter, _ComponentFilter, COMPONENT_PREFIXES,
set/clear_session_context(), gateway.log creation in setup_logging()
- gateway/run.py: removed redundant gateway.log handler (now in hermes_logging)
- run_agent.py: set_session_context() at start of run_conversation()
- hermes_cli/logs.py: --component filter, logger name extraction
- hermes_cli/main.py: --component argument on logs subparser
Addresses community request for component-separated, filterable logging.
Zero changes to existing logger names — __name__ already provides hierarchy.
* fix: use LogRecord factory instead of per-handler _SessionFilter
The _SessionFilter approach required attaching a filter to every handler
we create. Any handler created outside our _add_rotating_handler (like
the gateway stderr handler, or third-party handlers) would crash with
KeyError: 'session_tag' if it used our format string.
Replace with logging.setLogRecordFactory() which injects session_tag
into every LogRecord at creation time — process-global, zero per-handler
wiring needed. The factory is installed at import time (before
setup_logging) so session_tag is available from the moment hermes_logging
is imported.
- Idempotent: marker attribute prevents double-wrapping on module reload
- Chains with existing factory: won't break third-party record factories
- Removes _SessionFilter from _add_rotating_handler and setup_verbose_logging
- Adds tests: record factory injection, idempotency, arbitrary handler compat
* feat(nix): container-aware CLI — auto-route all subcommands into managed container
When container.enable = true, the host `hermes` CLI transparently execs
every subcommand into the managed Docker/Podman container. A symlink
bridge (~/.hermes -> /var/lib/hermes/.hermes) unifies state between host
and container so sessions, config, and memories are shared.
CLI changes:
- Global routing before subcommand dispatch (all commands forwarded)
- docker exec with -u exec_user, env passthrough (TERM, COLORTERM,
LANG, LC_ALL), TTY-aware flags
- Retry with spinner on failure (TTY: 5s, non-TTY: 10s silent)
- Hard fail instead of silent fallback
- HERMES_DEV=1 env var bypasses routing for development
- No routing messages (invisible to user)
NixOS module changes:
- container.hostUsers option: lists users who get ~/.hermes symlink
and automatic hermes group membership
- Activation script creates symlink bridge (with backup of existing
~/.hermes dirs), writes exec_user to .container-mode
- Cleanup on disable: removes symlinks + .container-mode + stops service
- Warning when hostUsers set without addToSystemPackages
* fix: address review — reuse sudo var, add chown -h on symlink update
- hermes_cli/main.py: reuse the existing `sudo` variable instead of
redundant `shutil.which("sudo")` call that could return None
- nix/nixosModules.nix: add missing `chown -h` when updating an
existing symlink target so ownership stays consistent with the
fresh-create and backup-replace branches
* fix: address remaining review items from cursor bugbot
- hermes_cli/main.py: move container routing BEFORE parse_args() so
--help, unrecognised flags, and all subcommands are forwarded
transparently into the container instead of being intercepted by
argparse on the host (high severity)
- nix/nixosModules.nix: resolve home dirs via
config.users.users.${user}.home instead of hardcoding /home/${user},
supporting users with custom home directories (medium severity)
- nix/nixosModules.nix: gate hostUsers group membership on
container.enable so setting hostUsers without container mode doesn't
silently add users to the hermes group (low severity)
* fix: simplify container routing — execvp, no retries, let it crash
- Replace subprocess.run retry loop with os.execvp (no idle parent process)
- Extract _probe_container helper for sudo detection with 15s timeout
- Narrow exception handling: FileNotFoundError only in get_container_exec_info,
catch TimeoutExpired specifically, remove silent except Exception: pass
- Collapse needs_sudo + sudo into single sudo_path variable
- Simplify NixOS symlink creation from 4 branches to 2
- Gate NixOS sudoers hint with "On NixOS:" prefix
- Full test rewrite: 18 tests covering execvp, sudo probe, timeout, permissions
