The post-graceful-drain is-active poll used a fixed 10s timeout, but
systemd's hermes-gateway.service has RestartSec=30 — so systemd won't
respawn the unit for 30s after exit-75, and our poll gives up during
the cooldown. Result: every 'hermes update' printed
⚠ hermes-gateway drained but didn't relaunch — forcing restart
followed by a redundant 'systemctl restart' that kicked the newly-
respawning gateway again (and re-started WhatsApp / Discord a second
time in the process).
Fix: read RestartUSec from the unit via 'systemctl show' and set the
poll budget to max(10s, RestartSec + 10s slack). Units without
RestartSec set (or value=infinity) fall back to the original 10s.
Observed timeline from journalctl before fix:
08:56:22.262 old PID exits 75
08:56:32.707 systemd logs Stopped -> Started (10.4s gap, > 10s budget)
After fix the poll covers 40s — comfortably inside RestartSec + slack.
Validation:
- RestartUSec parser tested against '30s', '100ms', '1min 30s',
'infinity', '', 'garbage', '500us', '2min' — all correct.
- Against the live hermes-gateway.service: parses to 30.0s.
- tests/hermes_cli/test_update_gateway_restart.py: 41/41 pass.
Makes hermes -z usable by sweeper without mutating user config.
- Top-level -m/--model and --provider flags that apply to -z/--oneshot
(mirrors hermes chat's plumbing).
- HERMES_INFERENCE_MODEL env var as the parallel to HERMES_INFERENCE_PROVIDER
for CI / scripted invocations.
- resolve_runtime_provider() gets the requested provider; when --model is
given without --provider, detect_provider_for_model() auto-selects the
provider that serves it (same semantic as /model in an interactive session).
- --provider without --model errors out with exit 2 — carrying a config
model across to a different provider is usually wrong, and silently
picking the provider's catalog default hides the mismatch.
Config defaults still used when both flags are omitted (existing behavior).
Validation (all live against OpenRouter):
-z 'x' ....................... uses config default (opus-4.7)
-z 'x' --model haiku-4.5 ..... haiku-4.5 via auto-detected openrouter
-z 'x' --model ... --provider pair as given
HERMES_INFERENCE_MODEL=... -z haiku-4.5 via env var
-z 'x' --provider anthropic .. exits 2 with error to stderr
* feat: add `hermes -z <prompt>` one-shot mode
Top-level flag that runs a single prompt and prints ONLY the final
response text to stdout. No banner, no spinner, no tool previews, no
session_id line — stdout is machine-readable, stderr is silent.
Tools, memory, rules, and AGENTS.md in the CWD are loaded as normal.
Approvals are auto-bypassed (sets HERMES_YOLO_MODE=1 for the call).
Bypasses cli.py entirely — goes straight to AIAgent.chat().
* feat(oneshot): handle interactive-callback gaps explicitly
Document (and where needed, patch) the interactive surfaces that have
no user to answer in oneshot mode:
- clarify — inject a callback that tells the agent to pick the
best default and continue (previously returned a
generic 'not available in this execution context'
error that wastes a tool call)
- sudo password — terminal_tool already gates on HERMES_INTERACTIVE
(we don't set it); sudo fails gracefully
- shell hooks — HERMES_ACCEPT_HOOKS=1 auto-approves; also falls
back to deny on non-tty stdin
- dangerous cmd — HERMES_YOLO_MODE=1 short-circuits before input()
- secret capture— tool returns gracefully when no callback wired
Live-tested: agent asked clarify(['red','blue']) and got 'red' back,
replied with only 'red'.
The AIAgent.flush_memories pre-compression save, the gateway
_flush_memories_for_session, and everything feeding them are
obsolete now that the background memory/skill review handles
persistent memory extraction.
Problems with flush_memories:
- Pre-dates the background review loop. It was the only memory-save
path when introduced; the background review now fires every 10 user
turns on CLI and gateway alike, which is far more frequent than
compression or session reset ever triggered flush.
- Blocking and synchronous. Pre-compression flush ran on the live agent
before compression, blocking the user-visible response.
- Cache-breaking. Flush built a temporary conversation prefix
(system prompt + memory-only tool list) that diverged from the live
conversation's cached prefix, invalidating prompt caching. The
gateway variant spawned a fresh AIAgent with its own clean prompt
for each finalized session — still cache-breaking, just in a
different process.
- Redundant. Background review runs in the live conversation's
session context, gets the same content, writes to the same memory
store, and doesn't break the cache. Everything flush_memories
claimed to preserve is already covered.
What this removes:
- AIAgent.flush_memories() method (~248 LOC in run_agent.py)
- Pre-compression flush call in _compress_context
- flush_memories call sites in cli.py (/new + exit)
- GatewayRunner._flush_memories_for_session + _async_flush_memories
(and the 3 call sites: session expiry watcher, /new, /resume)
- 'flush_memories' entry from DEFAULT_CONFIG auxiliary tasks,
hermes tools UI task list, auxiliary_client docstrings
- _memory_flush_min_turns config + init
- #15631's headroom-deduction math in
_check_compression_model_feasibility (headroom was only needed
because flush dragged the full main-agent system prompt along;
the compression summariser sends a single user-role prompt so
new_threshold = aux_context is safe again)
- The dedicated test files and assertions that exercised
flush-specific paths
What this renames (with read-time backcompat on sessions.json):
- SessionEntry.memory_flushed -> SessionEntry.expiry_finalized.
The session-expiry watcher still uses the flag to avoid re-running
finalize/eviction on the same expired session; the new name
reflects what it now actually gates. from_dict() reads
'expiry_finalized' first, falls back to the legacy 'memory_flushed'
key so existing sessions.json files upgrade seamlessly.
Supersedes #15631 and #15638.
Tested: 383 targeted tests pass across run_agent/, agent/, cli/,
and gateway/ session-boundary suites. No behavior regressions —
background memory review continues to handle persistent memory
extraction on both CLI and gateway.
The auto-restart path in `hermes update` verifies systemd unit health with
`time.sleep(3)` + a single `systemctl is-active` call. The unit's
Stopped -> Started transition after a graceful SIGUSR1 exit (or a hard
restart) is not always complete inside that 3s window, so the verify
races and reports 'drained but didn't relaunch' even though systemd is
about to bring the unit back up a fraction of a second later. Users
then see a spurious warning, a redundant fallback `systemctl restart`
fires, and adapters (Discord, WhatsApp) get restarted twice.
Replace the three sleep+oneshot sites with a small `_wait_for_service_active()`
closure that polls `is-active` every 0.5s for up to 10s. Behaviour
is unchanged when the unit is healthy or truly dead — only the race
window around a clean restart is now handled correctly.
Tests: tests/hermes_cli/test_update_gateway_restart.py (41/41).
Bug 3 — Stale OAuth token not detected in 'hermes model':
- _model_flow_anthropic used 'has_creds = bool(existing_key)' which treats
any non-empty token (including expired OAuth tokens) as valid.
- Added existing_is_stale_oauth check: if the only credential is an OAuth
token (sk-ant- prefix) with no valid cc_creds fallback, mark it stale
and force the re-auth menu instead of silently accepting a broken token.
Bug 4 — macOS Keychain credentials never read:
- Claude Code >=2.1.114 migrated from ~/.claude/.credentials.json to the
macOS Keychain under service 'Claude Code-credentials'.
- Added _read_claude_code_credentials_from_keychain() using the 'security'
CLI tool; read_claude_code_credentials() now tries Keychain first then
falls back to JSON file.
- Non-Darwin platforms return None from Keychain read immediately.
Tests:
- tests/agent/test_anthropic_keychain.py: 11 cases covering Darwin-only
guard, security command failures, JSON parsing, fallback priority.
- tests/hermes_cli/test_anthropic_model_flow_stale_oauth.py: 8 cases
covering stale OAuth detection, API key passthrough, cc_creds fallback.
Refs: #12905
- probe_api_models: add api_mode param; use x-api-key + anthropic-version
headers for anthropic_messages mode (Anthropic's native Models API auth)
- probe_api_models: add User-Agent header to avoid Cloudflare 403 blocks
on third-party OpenAI-compatible endpoints
- validate_requested_model: pass api_mode through from switch_model
- validate_requested_model: for anthropic_messages mode, attempt probe with
correct auth; if probe fails (many proxies don't implement /v1/models),
accept the model with an informational warning instead of rejecting
- fetch_api_models: propagate api_mode to probe_api_models
Cron jobs can now specify a per-job working directory. When set, the job
runs as if launched from that directory: AGENTS.md / CLAUDE.md /
.cursorrules from that dir are injected into the system prompt, and the
terminal / file / code-exec tools use it as their cwd (via TERMINAL_CWD).
When unset, old behaviour is preserved (no project context files, tools
use the scheduler's cwd).
Requested by @bluthcy.
## Mechanism
- cron/jobs.py: create_job / update_job accept 'workdir'; validated to
be an absolute existing directory at create/update time.
- cron/scheduler.py run_job: if job.workdir is set, point TERMINAL_CWD
at it and flip skip_context_files to False before building the agent.
Restored in finally on every exit path.
- cron/scheduler.py tick: workdir jobs run sequentially (outside the
thread pool) because TERMINAL_CWD is process-global. Workdir-less jobs
still run in the parallel pool unchanged.
- tools/cronjob_tools.py + hermes_cli/cron.py + hermes_cli/main.py:
expose 'workdir' via the cronjob tool and 'hermes cron create/edit
--workdir ...'. Empty string on edit clears the field.
## Validation
- tests/cron/test_cron_workdir.py (21 tests): normalize, create, update,
JSON round-trip via cronjob tool, tick partition (workdir jobs run on
the main thread, not the pool), run_job env toggle + restore in finally.
- Full targeted suite (tests/cron/, test_cronjob_tools.py, test_cron.py,
test_config_cwd_bridge.py, test_worktree.py): 314/314 passed.
- Live smoke: hermes cron create --workdir $(pwd) works; relative path
rejected; list shows 'Workdir:'; edit --workdir '' clears.
agent/redact.py snapshots _REDACT_ENABLED from HERMES_REDACT_SECRETS at
module-import time. hermes_cli/main.py calls setup_logging() early, which
transitively imports agent.redact — BEFORE any config bridge has run. So
users who set 'security.redact_secrets: false' in config.yaml (instead of
HERMES_REDACT_SECRETS=false in .env) had the toggle silently ignored in
both 'hermes chat' and 'hermes gateway run'.
Bridge config.yaml -> env var in hermes_cli/main.py BEFORE setup_logging.
.env still wins (only set env when unset) — config.yaml is the fallback.
Regression tests in tests/hermes_cli/test_redact_config_bridge.py spawn
fresh subprocesses to verify:
- redact_secrets: false in config.yaml disables redaction
- default (key absent) leaves redaction enabled
- .env HERMES_REDACT_SECRETS=true overrides config.yaml
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.
Reported by @GeoffWellman and @ANT_1515 on X.
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.
