Integrates the three Prime-Agent (PrimeIntellect-ai/prime-agent) harness
features that fit Hermes' architecture, adapted rather than ported:
- /goal gate add <cmd>: deterministic quality gates on the goal loop.
Gates run at turn boundary BEFORE the LLM judge; a failing gate's
bounded output becomes the continuation prompt, unchanged workspaces
(git fingerprint) are not re-run, retries are bounded with auto-pause.
- /heartbeat every <interval> <prompt>: one recurring re-entry prompt
per session, injected as a plain user turn only when idle; missed
ticks coalesce; state persists in SessionDB and migrates across
compression rotations. CLI watchdog thread + gateway-wide poller.
- /refine [focus]: user-triggered run of the existing background
memory/skill review fork, with optional focus instructions appended
to the review prompt. Automatic reviews are byte-identical to before.
RLM (IPython-only tool surface) deliberately excluded per request; the
daemon/worker detach layer and root-session A2A messaging are covered
by the gateway, sessions DB, delegation, and send_message and were not
duplicated.
All three features are cache-safe (plain user-role injections, no
system-prompt mutation) and alternation-safe.
The dashboard now mints an action_id per backend update, hands it to the
spawned `hermes update` via HERMES_ACTION_ID, and reuses an in-flight
update action instead of spawning a duplicate. The updater prints a
bounded `=== hermes-update completed <id> ===` receipt on every success
path — normal, zip, dependency-repair, and the no-op "Already up to
date!" path that previously ended with no terminal marker at all
(#58764) — so the Desktop can prove completion across the dashboard
restart boundary instead of guessing from stale log text.

On Linux a freshly-built desktop app had no presence in the application
launcher: no Hermes in the KDE/GNOME menu, no icon, nothing to pin. Users
had to hand-write ~/.local/share/applications/hermes.desktop and remember
to reindex the menu caches themselves.
`hermes desktop` now writes that entry itself (best-effort, idempotent,
never blocking a launch), and `hermes uninstall --gui` removes it again.
Both fields that matter are absolute:
- Exec — the launcher runs with a minimal environment and no shell PATH
customizations, so a bare `hermes desktop` silently fails for anyone
whose hermes lives in ~/.local/bin or a venv. We resolve the real binary
via relaunch.resolve_hermes_bin(), falling back to an absolute
interpreter + `-m hermes_cli.main`.
- Icon — an unqualified name only resolves against an indexed icon theme,
which we are not in. The spec allows an absolute path, so we point at
apps/desktop/assets/icon.png in the checkout. No copy is installed: Exec
already depends on that same tree, so a second copy would add bytes and
an uninstall step without surviving anything Exec wouldn't.
Menu-cache refresh is tool-gated — update-desktop-database, then
kbuildsycoca6 or kbuildsycoca5 — each only when the binary is actually on
PATH, because most desktops ship none of them and a missing one is not an
error. The entry is only rewritten when its contents change, so a launch
doesn't churn the caches every run.
Verified on NixOS: the generated entry passes desktop-file-validate, a
real kbuildsycoca6 on PATH is invoked with --noincremental, a real
update-desktop-database writes mimeinfo.cache, absent tools are skipped
cleanly, and removal leaves the checkout's icon untouched.
The gateway terminal guard crashed with 'ValueError: embedded null byte'
(command never ran, exit_code -1) when a command invoked an ELF binary by
full path. _read_referenced_script correctly rejects the binary locally
(NUL in first chunk), but the read_remote_script fallback
(_read_script_in_env) then re-read the SAME file's bytes without a NUL
guard, decoded them, and fed machine code back into the scanner, which
re-tokenized it into a bogus NUL-bearing path and crashed at os.open.
- _read_script_in_env: skip content containing a NUL byte on both the
local-read and remote-cat branches (mirrors _read_referenced_script:
a binary is nothing to scan), so binary never re-enters the guard.
- _read_referenced_script: tolerate ValueError from os.open on a
NUL-in-path, alongside the existing OSError guard, so the guard can
never crash the terminal tool regardless of input.
Extends the #76762 NUL-safety fix (local path only) to the gateway's
remote-read fallback path.
_skin_set has no try/except around yaml.safe_load, so invalid YAML raises
and aborts the command. The {} fallback comes only from safe_load()
returning None on a zero-length file — which is exactly the state a torn,
unsynced write leaves behind, so the data-loss chain is unchanged.
`write_profile_meta` and `hermes skin set` are both read-modify-write
helpers that rewrite a user-visible YAML file with a bare truncating
write, bypassing `utils.atomic_yaml_write` — the shared helper whose
docstring states that "every destructive file rewrite in the codebase
shares one implementation".
Both read halves swallow a parse error and fall back to `{}`, so a
truncated file is not transient corruption. The next call reads `{}` and
silently, permanently drops every field the caller did not explicitly
pass:
* `write_profile_meta` promises "unspecified fields preserve existing
values". After an interrupted write, a follow-up call that only sets
`description_auto` erases the profile's `description` — it vanishes
from `hermes profile list` and never comes back.
* `_skin_set` exists so that "changing one token never disturbs the rest
of the look". `path.write_text(...)` neither fsyncs nor swaps
atomically, so a crash or power loss can leave `<skin>.yaml`
zero-length; the next tweak then rewrites from empty and the whole
palette is gone. The gateway's skin watcher repaints live surfaces
from this file within ~1s, so a half-written file is observable.
Routing both through `atomic_yaml_write` gives temp file + fsync +
`atomic_replace`, which also preserves a symlinked target (GitHub
#16743) and restores owner/mode, and emits emoji descriptions as real
UTF-8 instead of `\UXXXXXXXX` escapes (GitHub #51356).
Supersedes #51808, which fixed the unicode-escaping symptom alone by
adding `allow_unicode=True` to the same `yaml.safe_dump` call.
A dispatched console handler that calls sys.exit("message") or
raise SystemExit("message") sets exc.code to a string. int(exc.code or 0)
then raises ValueError, which is not a ConsoleCommandError, so it escapes
execute()'s handler and crashes the local REPL on an ordinary user mistake
(e.g. removing a credential that does not exist). Treat a string exit code
as a status-1 failure carrying that message.
Timing out a bounded git probe must not leave helper descendants
(credential helpers, git-remote-https, hook children) running after the
probe fails open. bounded_git_probe now spawns the child in its own
process group on POSIX (process_group=0), and _kill_git_process_tree
signals the whole group with os.killpg — gated on the child actually
leading its own group (pgid == pid), so a shared-group spawn can never
take down unrelated processes. Windows keeps the existing taskkill /T /F
tree kill.
Proven live on main: a fake git that forks a 300s descendant left the
descendant running after the probe timeout; with the fix the descendant
dies with the launcher. Fast path and fail-open contract unchanged.
Port of openai/codex#36793 (Terminate timed-out Git process trees).
Selecting an NVIDIA NIM model whose id reached config without the nvidia/
prefix produced a bare "HTTP 404: 404 page not found" — retried three times,
never naming the model. It reads exactly like an outage or an auth failure,
which is where the Discord thread spent its time before the id was spotted.
normalize_model_for_provider() had no branch for nvidia, so a bare id passed
straight through to the API. Repair it from the provider's curated catalogue:
a bare name that matches exactly one entry modulo the prefix gets it back.
That's a lookup, not a guess — build.nvidia.com also fronts local NIM
containers and third-party models, and anything absent from the catalogue is
left alone. Because the repair runs on every runtime setup, an already-broken
config self-heals on the next turn and prints what it changed.
If a bare id still reaches the wire, the 404 now explains itself. The
classifier consults the same catalogue: a prefix-less id the provider only
serves as vendor/model is a deterministic failure, so it classifies as
model_not_found instead of burning three retries on a retryable "unknown",
and the error trace names the id to use.
Fixes#78796
hermes debug share runs on the backend. A desktop app connected to a
remote, docker, or SSH backend writes desktop.log on the client machine,
so the bundle can never contain it — and the report rendered that as a
bare "(file not found)", which reads as "the app logged nothing" and
sends triage after a client-side bug it cannot see.
Name the writer and the path to collect by hand. Backend-written logs
are unchanged, a present desktop.log is still captured, and an empty one
still reports "(file empty)" — the app ran and logged nothing is a
different fact from the file being on another host.
Teknium's review on #63457: existing tests pin the final boolean but not
that the slow PROVIDER_REGISTRY sweep is skipped. Add three tests that
booby-trap hermes_cli.auth.get_auth_status and verify
_has_any_provider_configured() short-circuits on:
- config.yaml model.provider
- config.yaml base_url/api_key (custom endpoint shape)
- auth.json active_provider (sweep-only call-pattern guard)
Mutation-checked: reverting the reorder makes all three fail.
test_custom_provider_context_avoids_false_shrink_warning used
qwen3.8-max-preview as a slug that deliberately falls through to the
generic 'qwen' 131K catalog match. The new qwen3.8-max
DEFAULT_CONTEXT_LENGTHS entry (1M) now substring-matches the preview
slug too, so the no-custom-providers branch stopped warning. Swap the
fixture to qwen3.9-max-preview, which still hits the generic fallback
— the test's intent (custom_providers threading) is unchanged.
Simplify-pass follow-up on the #70782 salvage: _bearer_auth_headers
hard-emits ${MCP_<NAME>_API_KEY} but install_entry only persists
auth.env-declared vars — a manifest naming its key differently (the
shipped n8n style) would install cleanly yet send a literal-placeholder
header at connect time (silent 401, the #37792 bug class). Enforce the
naming contract at parse time. Also pins the secret-stays-in-.env
property in the install test (raw config.yaml carries the template,
never the secret). Mutation-checked: validation disabled -> guard test
fails.
When an optional-mcps manifest declares transport.type=http with
auth.type=api_key, install_entry() prompts for the key and saves it to
.env, but _build_server_config() only handled the oauth case — the
api_key case produced a bare url entry with no headers, so every
request to the server was unauthenticated (-> 401).
Reuse _bearer_auth_headers(entry.name) from mcp_config.py so the
catalog path emits the same 'Authorization: Bearer ${MCP_..._API_KEY}'
template as the manual 'hermes mcp add --url' path.

Three fixes for the Desktop/TUI cold-start stall where the event loop
is blocked for ~14s between HERMES_BACKEND_READY and the first
prompt (#60800):
1. copilot_auth: skip subprocess fallback when any
Copilot env var is explicitly set (even if invalid). The user
expressed token intent via env var; silently substituting a CLI
token is surprising and the subprocess adds up to 5s on Windows.
2. tui_gateway/ws: run resolve_skin() via asyncio.to_thread so config
loading + skin engine init do not block the WS read loop during
the cold-start RPC burst.
3. web_server: extend _warm_gateway_module to pre-import the heavy
module chains (auth, copilot_auth, runtime_provider, skin_engine,
inventory, model_switch) that the first WS connection + RPC burst
would otherwise import on the loop thread. These trigger .pyc
compilation and Defender scans on Windows (15-30s per the existing
comment) and were not covered by the original gateway-only warm.
Tests: 5 new tests in test_cold_start_gil_stall.py + 2 new tests in
test_copilot_auth.py. All 36 copilot_auth tests + 16 ws/web_server
tests pass.
Every hashed bundle chunk under /assets/ was served with no caching
directives, so each dashboard load re-fetched (or at best revalidated)
every JS/CSS chunk. Those filenames carry a Vite content hash — the
bytes behind a given URL can never change; a rebuild mints new
filenames referenced by a freshly served index.html.
Mark them Cache-Control: public, max-age=31536000, immutable:
- the /assets StaticFiles mount, via a subclass that stamps the header
on 200s only (404s stay uncached — a rebuild can create the file),
- serve_css, preserving its X-Forwarded-Prefix url() rewrites for
/fonts/, /fonts-terminal/, /ds-assets/, /assets/.
index.html keeps no-store, no-cache, must-revalidate — it is the
mutable entry point that binds users to the current hashes.
The original PR also added hand-rolled per-request gzip compression of
asset responses; that part is deliberately dropped. This server is a
localhost-default dashboard backend: compressing every response on the
CPU to save loopback bandwidth is a pessimization, and callers that
front it with a real proxy already get compression there.
Salvaged from PR #28543 (idea by @sea-monsters; gzip groups dropped as
described above).

le=100 would 422 real desktop callers: sessions-settings fetches
archived at limit=200, the command palette lists at 200, and the
electron remote-merge over-fetches limit+offset (exceeds 100 at
offset>=81, and its .catch(()=>null) silently drops remote sessions).
Clamp must sit above real client maxima. New test pins limit=200 w/
offset.
Re-derivation of aydnOktay's twin clamp PRs onto current main (the
session-list endpoints moved into web_routers/; the analytics endpoints
gained asyncio.to_thread wrappers since the originals):
- limit le=100 on /api/sessions, /api/sessions/search and the
/api/profiles/sessions fan-out (one unbounded request could drag every
session row + correlated-subquery preview work out of SQLite, times
every profile's state.db on the fan-out).
- days ge=1 le=365 on /api/analytics/usage + /api/analytics/models
(huge or non-positive values force full-history InsightsEngine work or
inverted windows; the UI only offers 7/30/90 presets).
FastAPI Query bounds reject at the validation layer (422). 8 new tests;
both clamp classes mutation-checked (clamp removed -> its tests fail).
The 2-line alias had zero production consumers (web_server calls
get_usage_breakdown directly). Tests rewired onto the real API; the
contracts they pin are unchanged. Stale test docstring fixed.
On dashboard-only sessions nothing else executes check_fn warmers (they
live only in the tool-schema build), so the hub's read-only cache lookup
would report auth_required=False forever. On a cache miss, schedule a
deduplicated daemon-thread probe off the request path; the short hub TTL
surfaces the verdict on the next fetch.
The as_completed drain + `with` join made the parallel version WORSE than
sequential main in the common case (first endpoint succeeds fast, others
slow/unreachable): main returned at first success, the parallel version
waited for every straggler. Now: after each completion, walk endpoints in
priority order and return as soon as a success is unbeatable (all
higher-priority probes already finished); pool uses shutdown(wait=False) so
losers drain in the background. Mutation-checked: removing the early exit
makes the new timing test fail (8.2s vs <1.5s).
Rebase fold: the original PR predates ZAI_ENDPOINTS growing per-endpoint
probe_models lists; the parallel worker now preserves that candidate-model
fallback loop (was: scalar model). Tests (both mutation-checked):
- candidate-model fallback within one endpoint worker
- ZAI_ENDPOINTS priority order wins over completion order
- all-fail returns None
