session.workspace.move refused a running live session with 4009
(session busy), but the desktop's Move-to-project flow calls exactly
this RPC — so the UI updated its local grouping while state.db kept the
old cwd and the agent's tools kept running in the old workspace. Two
sources of truth disagreed (#86626).
An explicit move now wins: the stored row and the live session re-anchor
together. In-flight tool calls keep the cwd they were launched with; the
next tool call uses the new workspace.
The "Conversation started:" line carried a bare date (%A, %B %d, %Y). Tools
that accept instants -- nutrition, calendar and similar MCP servers -- reject
naive datetimes and require an explicit UTC offset, so the model had to infer
EST vs EDT from the date alone. Near a DST boundary that is a coin flip, and a
wrong guess does not error: it silently writes the record onto the wrong day.
Append the IANA zone (when configured), the zone abbreviation and the UTC
offset, e.g.:
Conversation started: Saturday, August 15, 2026 (America/New_York, EDT, UTC-04:00)
get_timezone() returns None when no timezone is configured; in that case the
line falls back to the abbreviation and offset of the server-local (still
tz-aware) time, so behaviour is unchanged for users who never set one:
Conversation started: Saturday, August 15, 2026 (EDT, UTC-04:00)
Daily byte-stability is preserved -- the property the date-only format exists
to protect (PR #20451). Zone name, abbreviation and offset are all constant for
the whole day; they shift only at a DST transition, where a change is correct.
The static-prefix reconstruction guard in _restore_plugin_sections matches on
"\n\nConversation started:" and is unaffected by a suffix after the date.
test_datetime_is_date_only_not_minute_precision used `re.search(r":\d{2}")`
over the whole line as a proxy for "no time-of-day". A UTC offset also matches
that pattern, so the check now applies to the date portion (everything before
the zone parenthetical) and the invariant is tightened rather than relaxed:
- test_datetime_includes_utc_offset asserts the offset is present
- test_datetime_line_is_stable_across_rebuilds asserts two rebuilds in the
same day produce a byte-identical line

reapOrphans() treats any recorded backend with a matching process identity
as orphan-reapable — including a backend owned by another live instance. The
ownership file is shared across instances, so a second launch that reaches
reap (even without the lock) SIGTERMs the running instance's backend.
Claims now record the spawning Electron (parentPid + parentStartMarker, the
same values already passed to the backend as HERMES_PARENT_PID /
HERMES_PARENT_START_MARKER), and reapOrphans() skips any entry whose parent
is still running. Even a second instance that wins a stale lock can never
kill a live instance's backend. Legacy entries without parent data keep the
old behaviour.
Known tradeoff: a parent-liveness probe failure preserves the record, so a
genuinely orphaned backend under a still-running parent is leaked until it
dies naturally. That is preferable to killing a live instance's backend.
Tests: parent-aware reap in backend-ownership.test.ts (live parent
preserved, dead parent still reaped, probe failure preserved, parent
identity round-trips through claim/parse).
startHermes() is the only entry point that can reap, spawn, claim, and
therefore destroy a backend. Belt-and-suspenders on the exact killing line:
even if some future path reaches it in a lock-losing process (a refactor, a
dev harness, a race), the instance stays inert — no reap, no spawn, no
claim — instead of SIGTERMing the running instance's backend (#87295).
app.quit() does not stop a lock-losing instance from reaching whenReady:
the before-quit teardown coordinator defers the quit (event.preventDefault
+ async backend shutdown), and ready fires in that window. The losing
instance then runs the full startup whose reapOrphans() SIGTERMs the
running instance's live backend (#87295).
The lock-loser holds no state and no backend — requestSingleInstanceLock()
has already delivered the argv to the primary by the time it returns false —
so there is nothing to clean up. app.exit(0) terminates immediately, before
ready, so a second launch routes into the running window and never touches
backend machinery.
Adds a bounded fallback path in turn_finalizer.py that always records
a terminal timed_out outcome via _record_task_failure (CAS receipt path)
when the iteration budget is exhausted, regardless of whether the normal
fallback paths (interrupted/failed/anomalous exit_reason) were eligible.
Previously, a kanban worker whose budget was exhausted but whose turn was
interrupted, failed, or exited with an anomalous reason would silently
leave its task in an ambiguous lifecycle state — the dispatcher would
eventually detect it as a crashed or protocol-violation worker, but the
failure was not bounded and could take a full tick cycle to reconcile.
The CAS invariant in _end_run (WHERE ended_at IS NULL) guarantees
idempotence: if another path already closed the run, the call is a no-op.
Extracted the inline kanban-budget-exhausted recording into a shared
helper function (_record_kanban_budget_exhausted) used by both the
existing iteration_limit_fallback path and the new bounded fallback path.
Closes#87096
hermes update decides restart ownership from the live grandchild argv,
not from an env marker. Newly generated plists now include the flag.
The stderr_timestamp wrapper upgrades only historical Hermes gateway
run shapes for stale plists and leaves arbitrary launchd children unmarked.
launchd only stamps XPC_SERVICE_NAME on its direct child. The timestamp
wrapper is that child, so the grandchild gateway sees XPC_SERVICE_NAME=0
and the supervised-conflict guard refuses the service's own spawn.
Forward HERMES_GATEWAY_EXTERNAL_SUPERVISOR=1 when the wrapper itself is
launchd-supervised. Interactive XPC_SERVICE_NAME=0 starts stay unmarked.
Fixes#86893
After the VBS/cmd launcher exits, Task Scheduler marks
Hermes_Gateway_* Ready while the detached gateway keeps running.
The orphan reaper only bailed on Running, then fail-opened the
parent-chain check and killed the live bot on desktop serve start.
Fixes#87001
hermes chat -q sets HERMES_INTERACTIVE=1 (for interactive sudo prompts) but
runs one turn with no user waiting to answer approval prompts. Previously a
dangerous command triggered the interactive gate, waited the full 300s
timeout, then failed closed — and the agent was effectively forced to work
around the block, often silently auto-approving via execute_code (which
auto-approves in non-gateway mode).
Add approvals.single_query_mode (default deny, mirror of cron_mode):
deny — block dangerous commands and execute_code deterministically with
a clear 'no user present' message (no 300s wait)
approve — auto-approve dangerous commands/execute_code in -q mode
cli.py marks the session with HERMES_SINGLE_QUERY_SESSION; the shared gate
(_run_approval_gate, check_all_command_guards, check_execute_code_guard)
treats -q as a deterministic non-interactive context when that marker is set.
execute_code, the -q escape hatch, now honors single_query_mode instead of
auto-approving headlessly. Includes tirith parity in the combined guard and
docs. Fixes#86878.
Review NIT: a malformed stored binding of just 'mod'/'ctrl' (never
produced by comboFromEvent) could pass the shape-only mod/ctrl check.
Reject bare-modifier bases in actionAllowedInInput and pin it in the
suite.
#86586 replaced the combo-based input gate (any Cmd/Ctrl chord fires
while typing) with an action allowlist that dropped session.new and
every other mod-chord not explicitly listed. ⌘N/⌘T/⌘⇧N and friends
became dead keys whenever focus was in the composer.
Restore the pre-regression rule: primary-modifier chords stay global
even in text fields; the allowlist now gates only bare/Shift/Alt combos,
so rebound letter keys can never hijack typing. Text-navigation chords
(Ctrl+Arrow/PgUp/PgDn) still stay with the input.
An MCP server exposing a native tool named read_resource (or
list_resources/list_prompts/get_prompt) collided with the auto-generated
resource/prompt utility of the same name. The registration collision
handler flagged the pair as ambiguous and skipped BOTH entries, so the
server's own tool became silently unavailable on every gateway boot.
Resolve this specific native-vs-utility collision in favour of the native
tool: keep it and drop the shadowed utility, which is only convenience
sugar for servers that expose no such tool of their own. The conservative
skip-everything path still applies to genuinely ambiguous collisions (two
or more native tools normalizing to one name), which we cannot
disambiguate. Add a regression test covering the native-tool-wins path.
Fixes#87112
A named --provider without -m used to swallow lookup failures and
silently keep the global model.default. Log the resolution error so
the fallback is visible.
hermes chat --provider <name> without -m sent the global model.default
to the custom endpoint. Named custom entries already expose
default_model via _get_named_custom_provider(); honor that when the
user selected the provider and did not pass an explicit model.
Fixes#86978
The fire-and-forget handler only caught asyncio.CancelledError and
Exception, so a SystemExit/KeyboardInterrupt escaping a turn (e.g. a
plugin calling sys.exit() in a tool call or summary-LLM path) skipped
the user-facing failure notification and surfaced only as 'Task
exception was never retrieved' — radio silence for the user.
Catch BaseException instead; send the failure notification first, then
re-raise SystemExit/KeyboardInterrupt to preserve shutdown semantics
for the loop's own signal handling. Other BaseExceptions stay contained.
Closes#86651
Python Fire serializes the return value of a wrapped function but does not
use that value as the process exit code. Error paths in main() that used
or therefore caused the process to exit 0, swallowing
fatal errors and argument-validation failures.
Raise SystemExit(1) on every error path so batch_runner returns a non-zero
exit code when it cannot run. Success paths (e.g. --list_distributions) are
left unchanged.
ClosesNousResearch/hermes-agent#86524.
Docker Desktop writes fpath=(~/.docker/completions ...) into .zshrc.
The referenced-script walk then opened that directory, saw a non-regular
file, and fail-closed — blocking source ~/.zshrc on every terminal
command. Directories are not scripts; devices stay fail-closed.
Fixes#86864.
Legacy custom_providers configs commonly used short/placeholder
api_keys ('123', 'm') for local no-auth services like Ollama --
harmless for the endpoint itself, since Ollama accepts any key or no
key. A stricter has_usable_secret(value, min_length=4) gate added
later now rejects these, but only the credential-POOL resolution path
lacked the same "no-key-required" exemption every OTHER resolution
path in this file already has for exactly this scenario:
- The config-based custom_providers fallback (non-pool path) already
ends with `api_key or "no-key-required"`.
- The "actual" provider's local-offline path already injects
ACTUAL_LOCAL_NOAUTH_PLACEHOLDER before the usable-secret gate for a
loopback base_url.
- _try_resolve_from_custom_pool() was the one gap: it returned the raw
short pool credential unchanged, which then failed the downstream
has_usable_secret() gate with a generic "No usable credentials found
for custom" error that contradicts setup.status ("configured
credentials" vs "runtime failed"), sending users hunting in the
wrong direction.
Fixed by substituting the same "no-key-required" placeholder when the
pool's stored credential fails has_usable_secret() AND the base_url
resolves to a loopback hostname (using the existing _loopback_hostname
helper, matching the exemption scope the issue itself requested:
localhost/127.0.0.1/::1 only, not arbitrary remote endpoints with a
genuinely-too-short key).
Added 4 regression tests extending the existing
test_runtime_provider_resolution.py file, following its established
credential-pool mocking pattern: the exact reported 3-char repro
('123'), a 1-char case, a non-loopback sanity check confirming the
exemption stays scoped (a short key for a remote endpoint is NOT
silently exempted), and a sanity check that a genuinely usable
loopback key passes through unmodified. Verified as a genuine
regression by reverting the fix and confirming 2 tests fail with the
exact raw short key leaking through unchanged.
59/59 pass in the extended test file; 14/14 across two more related
custom-provider test files (no regression).
The `computer_use` toolset (cua-driver) had no persistence branch in
_write_provider_config or _is_provider_active. When the Desktop GUI
sent PUT /api/tools/toolsets/computer_use/provider, the config write
was a no-op and _is_provider_active always returned False -- so the
"Use this backend" CTA reappeared on every refresh.
Add a computer_use_backend marker to the cua-driver provider entry
and handle it in the same pattern as web_backend / browser_backend:
- _write_provider_config now sets computer_use.backend = "cua"
- _is_provider_active now checks computer_use.backend
- _reconfigure_provider (interactive CLI) also persists the key

Three problems with install.sh --commit:
1. No validation: non-hex or too-short arguments passed through to git,
producing misleading errors.
2. Fetch failure swallowed by || true: abbreviated SHAs are refused by
GitHub's server ("couldn't find remote ref"), but the error was
silently ignored.
3. Checkout failure not checked: git checkout --detach with a missing
object produces a misleading "does not take a path argument" error
and the install continues unpinned, exiting 0.
Fix:
- Validate --commit is a 7-40 hex string up front
- Remove || true from fetch; fail with actionable message directing
users to full 40-char SHAs
- Check git checkout --detach result and fail hard on error
Fixes#87268
Both install-blocking npm install call sites (browser tools and TUI) ran
with --silent and no output capture, so failures printed only a generic
error message with no npm diagnostics.
Apply the same pattern used by the camofox install path: redirect npm
output to a temp file and replay it on failure, so users can see the
actual error (EBADENGINE, ETARGET, network timeout, registry 5xx, etc.).
Fixes#87340
Plugins deleting profiles via `cli.exec ['profile','delete',…]` bypass the
Electron-side DELETE /api/profiles interception (prepareProfileDeleteRequest),
so a live pool backend — e.g. one the roster's hover pre-warm just woke —
holds the profile dir open and the renderer's reconnect respawns it
mid-delete, recreating the directory (#52279). Bot Mode's right-click Delete
hits this every time because right-click hovers the row first.
Add host.deleteProfile(name) to the plugin SDK: routes through the same
teardown-routed REST path core's DeleteProfileDialog uses (backend teardown
first, next request routed away), rejects on 'default', and re-homes the app
to the default profile when the deleted profile was the live gateway's —
mirroring the core dialog's ordering.
Reported by @BkashJosi (Bot Mode: deleting a bot errors while its session
is awake).
Follow-up to the #62799 salvage: Desktop sends both defer_history and
omit_messages on a cold resume. Make explicit in the deferred branch that
defer_history supersedes omit_messages — the single history read happens in
the background hydration worker and the synchronous omit_messages read on
the cold-resume default path is skipped entirely, so the transcript is
never loaded twice for one resume.
The MCP tab's left column previously split the configured fleet and the
Nous-approved catalog behind a Servers/Catalog tab toggle. Installed
entries appeared in both views and the install button lived a tab flip
away from the list it fed.
Now one scrolling column: configured servers (live status, toggles,
probes) on top, a Catalog section below offering only entries not yet
installed. Installing moves the entry up into the fleet list; the
zero-servers empty state keeps the catalog visible beneath it instead
of hiding it behind a full-page invitation.
Bot Mode's Advanced view embeds this same McpTab via the plugin SDK, so
the unification mirrors there automatically.
- removed leftView state + TextTab toggle; section headers reuse the
existing tabServers/tabCatalog strings (no i18n changes)
- availableCatalog memo filters installed/name-clashing entries
- catalog memoized to satisfy react-hooks/exhaustive-deps
Attribution mapping for the PR #84982 salvage. The commit email is not

Apply findings from /simplify-code 3-agent review:
1. Extract _install_paired() inner helper — the Ctrl, Alt, and Shift
sections all repeated the same mok+csiu sequence generation pattern
(~30 lines of duplication). Now each section builds a dict and
delegates to _install_paired(modifier, mapping).
2. Replace 10 hardcoded Ctrl+digit lines with a loop matching the
Ctrl+letter pattern above it.
3. Fix misleading comment: claimed 'Ctrl+0 doesn't produce a control
byte' but chr(ord('0') & 0x1F) = 0x10 = ControlP. The code was
correct (maps directly to Keys.Control0..9); only the comment was
wrong.
4. Add comment explaining why Shift+letter maps both lowercase and
uppercase codepoints (some terminals send the already-shifted
codepoint with modifier=2).
5. Test fixture: snapshot/restore ANSI_SEQUENCES in teardown so 294
mappings don't leak into sibling test files (global mutable state).
