Applies the batch-disposition SALVAGE conditions from #64231: the hook id
moves to the taxonomy transform-family name, and run-all-then-pick-first
dispatch now logs a runtime warning when a valid-but-losing classification
is skipped (the #64714 skipped-transform rule). Chaining semantics are
stated explicitly at the VALID_HOOKS entry, the dispatch helper docstring,
and the hooks.md catalog row and detail section.
Rebased onto current main, where the OpenRouter tool-use 404 is now
handled natively (the bundled demo's exact reason to exist), so the demo
plugin is removed per the standalone-repo policy and every test now uses
a synthetic unclaimed error (fake provider, neutral message, no status
code) that no present or future built-in rule can claim.
classify_api_error is now explicitly Python-plugin-only: VALID_HOOKS
doubles as the shell-hook allow-list, but the shell response parser has
no channel for the classification directive, so shell registrations are
refused at config parse with a warning instead of being silently
ignored (new SHELL_UNSUPPORTED_HOOKS set + regression test).
The hook is documented in the hooks reference as the third
behavior-changing hook, with the full kwargs contract, return shape,
and the Python-only note.

Adds a plugin seam at the top of agent/error_classifier.classify_api_error()
(step 0, before the built-in pipeline) so model-provider plugins can classify
their provider's error quirks without patching core:
- New "classify_api_error" entry in VALID_HOOKS. Callbacks receive the parsed
error context (provider, model, status_code, error_type, error_code,
error_message, error_body, error, approx_tokens, context_length,
num_messages), self-scope on `provider`, and return None to pass or a dict
{"reason": "<FailoverReason name>", ...optional recovery-hint overrides}.
- get_plugin_error_classification() helper mirrors
get_pre_tool_call_block_message(): first valid result wins, invalid dicts
and unknown reasons are skipped, callback exceptions are isolated — a
broken plugin can never break classification. Zero behavior change when no
plugin claims the error (all 179 existing classifier tests pass untouched).
- Bundled reference plugin `openrouter-tool-use-404` (opt-in, like all
bundled standalone plugins) re-implements PR #58451: OpenRouter's
"No endpoints found that support tool use" 404 carries no
_MODEL_NOT_FOUND_PATTERNS signal, so it classifies as unknown/retryable
and the retry loop burns 3-5 attempts on a deterministic rejection.
The plugin classifies it as model_not_found (retryable=False,
should_fallback=True) so the fast-fallback path fires immediately —
demonstrating a waiting core PR converted to a publishable plugin.
Motivation: ~10 open PRs are single-provider error-classification patches
(#58451, #58355, #58502, #58474, #58366, ...). This hook turns that whole
class of contribution into plugin territory.

Per review: keep the load-bearing tests (fire+payload per hook, the
lock-probe contract test, misbehaving-subscriber isolation, no-subscriber
short-circuit, mutation-boundary coverage) and drop the auxiliary
variants; compress the hooks.md additions to a single catalog-row set
plus a compact bullet section.
Implements the remaining observers from RFC #58548 (@thebizfixer),
accepted as the design basis in the #64231 batch disposition:
- on_kanban_worker_spawned: fires in the dispatch loop after spawn_fn
returns and the worker PID is durably persisted (the RFC timing
contract), in both the ready and review lanes.
- on_kanban_worker_exited: tick-derived from detect_crashed_workers;
fires after every reclaim/accounting txn has committed, carrying
exit_kind / exit_code / outcome / retry_status.
- on_kanban_worker_stale_claim: fires when release_stale_claims
reclaims a TTL-expired claim; live-PID claim extensions and deferred
reclaims stay silent.
- on_kanban_task_updated: task-mutation boundary observer carrying
changed_fields (field names only); fired by assign_task,
set_model_override, and set_reasoning_effort, and by the dashboard
plugin API's direct-SQL priority/title/body editors (single and
bulk) through the new kanban_db.notify_task_updated seam.
- on_kanban_dispatch_tick: re-port of PR #56066 (@laboratoiresonore),
renamed per the taxonomy and fired strictly AFTER _dispatch_tick_lock
is released; the sweeper found the original fired inside the lock,
where a slow subscriber could extend the single-writer critical
section and stall a sibling dispatcher.
All five are observer-only (return values ignored), fire after the
relevant write txn commits, and short-circuit on has_hook() so nothing
is built when no consumer registers; every fire site is fully
best-effort so a broken plugin can never break dispatch or a task
mutation. No config surface added. Existing plugins and hook payloads
are untouched.
Mutation-boundary scope: every user-facing task-FIELD editor fires
(assignee, priority, title, body, model/provider override, reasoning
effort). Deliberately not wired: status transitions (they belong to
the lifecycle hook family), dispatcher bookkeeping columns
(worker_pid, workspace_path, claim columns — surfaced through the
worker hooks instead), link/comment/attachment tables (not task-row
writes), and the dispatcher's default-assignee auto-assign (already
surfaced via DispatchResult.auto_assigned_default in the tick
payload). notify_task_updated is the seam for wiring further paths.
Docs: new rows plus a detail section in the shipped plugin-hook catalog.
Tests: 30 new (9 worker lifecycle, 8 dispatch tick, 8 task updated,
5 dashboard mutation boundary), including a lock-probe contract test
that fails if the tick hook ever fires inside the dispatch lock.

delegate_task gains a control plane: action='list' / 'steer' / 'stop'
let the parent agent see, redirect, and early-stop its own running
subagents mid-flight — the model-facing counterpart of the TUI's
delegation.pause / subagent.interrupt / subagent.steer RPCs.
- action='list': live children of this conversation's spawn tree
(ids, goal, status, running_seconds, accepting_steer, live
transcript path). Ownership is enforced via a _delegate_parent_ref
weakref chain stamped at child build time, so a conversation can
only control its own descendants, never a sibling tree.
- action='steer': queues text into a running child via the existing
steer_subagent() registry path (delivered at the child's next tool
boundary; missed steers surface as missed_steer in the completion).
- action='stop': interrupt_subagent() — child stops at its next
iteration boundary, partial result still re-enters as a completion.
- Spawn dispatch response now includes subagent_ids + control hint.
- Control actions run synchronously (never backgrounded) and bypass
the spawn pause gate and depth limit; they also never consume the
per-turn subagent spawn cap, and remain usable once the cap is hit
(that is when stop matters most).
- Small-model robustness (found live with gpt-5.4-mini on Nous
Portal): tasks=[] alongside goal no longer trips the "Batch mode
requires at least 2 tasks" gate — treated as single-goal.
- CLI display: control calls render as "steer sa-…" / "list" instead
of an empty goal.
Live-tested E2E on Nous Portal (fable-5 + gpt-5.4-mini): full
spawn→list→steer→stop cycle, plus a steer-efficacy run where the
child acked the steer mid-essay and switched topics before finishing.
The session chat stream registered its wrapper task in _active_run_tasks,
but that turn is already counted by active_agent_work_count() via
_inflight_agent_runs (_run_agent) — the drain saw 2 for one turn
(test_session_chat_sse_turn_is_interrupted). Keep only the agent-ref
registration; run-scoped steer control doesn't need the task entry.
Adds POST /v1/runs/{run_id}/steer and bridges Browser-Extension/WebUI
session chat streams into the active run registry so live runs on those
surfaces are steerable too.
- steer accepted only while run status is exactly 'running'; stop/stopping/
terminal states return 409 run_not_accepting_steer even while cooperative
shutdown retains the agent reference
- session SSE disconnect/cancellation interrupts and drains the executor-
backed run instead of cancelling only the async wrapper; control refs stay
registered until the turn actually exits
- undelivered steer text (accepted after the final response) is preserved as
pending_steer on the terminal run.completed event/status so clients can
replay it as the next user turn instead of losing it
- docs for the endpoint, next-tool-boundary delivery, acceptance-vs-delivery
semantics
Salvaged from PR #54466 by @abundantbeing.
The cherry-picked guard sat inside the codex-items block, which (a) is
skipped entirely in codex_responses mode (conversation_loop passes
drop_codex_reasoning_items=False there) and (b) is unreachable for
carriers whose adapter-joined commentary populates msg['reasoning'] —
the string-reasoning branch returns True first. Hoist the checkpoint
check above every reasoning branch so no carrier shape can be dropped,
in any api_mode. Adds the two carrier-shape tests that pin exactly this
(both fail with the guard in its original position).
A type="compaction" item is the server-side stand-in for history that has
already been pruned, and it rides the same codex_reasoning_items sidecar as
per-turn reasoning. e00965a7e taught compaction pruning to filter that
sidecar instead of popping it so checkpoints survive on every retained
message.
The thinking-only sanitizer reaches the same sidecar from the other
direction and asks a coarser question: does any item have type ==
"reasoning"? A commentary turn carrying both a reasoning item and a
checkpoint answers yes, so the whole message is dropped from the wire copy
and the only copy of the checkpoint goes with it. The request then carries
neither the compacted history nor the checkpoint standing in for it.
Extract has_compaction_checkpoint() into agent/native_compaction.py — the
module that owns the concept, and where merge_interim_reasoning_items()
already spelled the same predicate inline — and consult it before the
thinking-only verdict. A reasoning-only carrier is still dropped.
Two reliability gaps from #82777:
1. Rejection matcher required only a field-name mention, so a transient
5xx/timeout whose body echoed the request (which contains
context_management) permanently downgraded native compaction for the
session. Now requires rejection language (unknown/unsupported/invalid/...)
alongside the field name, and when a parsed HTTP status is available,
400 specifically — non-400 statuses never match. Message-only transports
(no status attribute) keep working unchanged.
2. compression.codex_responses_native was coerced with bool(), so the
strings "false"/"off" enabled the feature. Now uses the shared
utils.is_truthy_value helper.
Conversation-loop call site passes api_error.status_code through.
Sabotage-verified: reverting the matcher to field-name-only fails the new
echo and non-400 tests.
Simplify-pass follow-ups on the salvage stack (all guard tests re-run,
mutation-checked):
1. conversation_loop.py: moved `_preflight_compression_blocked = False`
from 9 per-site copies into the restart_with_rebuilt_messages handler
(its single consumer). Besides removing the 9 duplicated blocks, this
fixes a 10th pre-existing retry-loop site (content-filter stall
failover, #32421) that set the flag and broke WITHOUT clearing the
preflight block — a content-filter failover previously restarted with
preflight compression still blocked against the fallback's smaller
window, the same #84733 bug class. The outer-loop empty-response site
keeps its own clear (it never passes through the handler). New AST
guard test_restart_handler_clears_preflight_block pins the hoisted
clear (mutation-checked).
2. agent_runtime_helpers.py: extracted _raw_cache_ttl_from_config() —
prompt_caching_disabled_from_config and configured_cache_ttl were
verbatim copies of the same config read. Added VALID_CACHE_TTLS.
3. prompt_caching.py: added is_qwen_model() next to
ALIBABA_FAMILY_PROVIDERS; effective_cache_ttl and
anthropic_prompt_cache_policy now share both the family set and the
qwen predicate — neither can desync.
4. Guard-test hardening: assert every _try_activate_fallback reference
is a direct `if agent._try_activate_fallback(...):` site, so a future
`activated = ...` form can't silently escape the restart-discipline
guard.
Follow-ups on the salvaged #84782 (webtecnica):
1. conversation_loop.py: the empty-response fallback site sits directly
in the OUTER iteration loop, not the retry loop. The salvaged commit's
`break` there exited the conversation loop and ended the turn without
ever calling the just-activated fallback (caught by CI:
test_empty_response_triggers_fallback_provider). Restored `continue`
(which already re-runs the pre-API preflight at the top of the next
outer iteration) while keeping the `_preflight_compression_blocked`
reset. The other 9 sites are inside the retry loop, where `break` to
the restart_with_rebuilt_messages handler is correct.
2. test_prompt_cache_ttl_propagation.py: made the AST guard loop-aware —
retry-loop sites must break, outer-loop sites must continue (the old
assertion pinned the bug in (1)). Mutation-checked both directions.
3. test_failover_identity.py: added `model` to the SimpleNamespace agent
fixture — _redecorate_prompt_cache_for_provider now reads agent.model
for the per-destination TTL clamp (2 CI failures).
4. prompt_caching.py / agent_runtime_helpers.py: single source of truth
for the alibaba-family provider set — ALIBABA_FAMILY_PROVIDERS lives
in prompt_caching and anthropic_prompt_cache_policy imports it, so the
cache-policy opt-in and the TTL clamp can never desync.
5. auxiliary_client.py: threaded the configured tier into
_replan_synchronous_cache_sections via new configured_cache_ttl()
(no live agent on that path) — the aux half of #84733's report also
stopped regressing 1h to 5m. Guarded by
TestAuxFallbackReplanThreadsTtl (mutation-checked).
6. Dropped the redundant `or "5m"` at the two threaded call sites —
effective_cache_ttl already resolves None to "5m", and the `or`
masked the cache-disabled (None) semantics.
Choosing Computer Use should be a config flip, not a hunt for
'hermes computer-use install'. Three provisioning rungs:
- install.sh / install.ps1 pre-install cua-driver (best-effort,
non-fatal, time-boxed at 660s above the upstream installer's 600s
lock window; --skip-computer-use / -SkipComputerUse to opt out;
Termux and unwritable-/Applications skipped cleanly)
- PUT /api/tools/toolsets/{name} (dashboard + desktop toggle) spawns
the background 'hermes tools post-setup cua_driver' action when the
toolset is enabled while the binary is missing — previously the
toggle 'saved' but the tool never appeared in the schema because
check_computer_use_requirements() couldn't find the binary
- hermes tools interactive flow already installed via
_toolset_needs_configuration_prompt/_POST_SETUP_INSTALLED (unchanged)
Docs: computer-use.md enabling section rewritten around the new flow;
installation.md documents --skip-computer-use.
_update_node_dependencies() installs the unified closure, but update then
calls _build_web_ui(), whose 'npm ci --workspace web' pass deleted
node_modules and re-reified only the web closure — pruning root
devDependencies and the ui-tui hoisted deps the previous step just
installed, while exiting 0. Since the manifests digest was already
recorded, later no-op updates skipped the repair.
Reported by @andrexibiza in the #44772 final review (P1). Reproduced
E2E: '--workspace web' alone removes typescript-eslint/@eslint/js from
root node_modules; the unified closure restores them.
Guards: ui-tui only named when its manifest exists (prebuilt checkouts),
web-own-lockfile (#42973) and Termux (#38772) paths unchanged.
check_subprocess_stdin.py already had a full-repo-scan pytest wrapper
(test_subprocess_stdin_guard.py), so a plain pytest run catches a
regression there without anyone remembering to run the script by
hand. check-windows-footguns.py had no equivalent (only a narrow
single-rule test existed), which is why the bare os.killpg/
signal.SIGKILL regression in the npx-agent-browser hardening commit
shipped past local testing and was only caught by CI running the
script directly. New test_windows_footguns_full_repo_scan.py mirrors
the stdin guard's exact pattern to close that asymmetry.
Also adds direct coverage for _kill_process_tree's getattr fallback
when os.killpg is missing, and asserts warm_agent_browser_npx_cache's
Popen call passes stdin=subprocess.DEVNULL as a literal argument.
ensure_browser() (install.sh) and Install-AgentBrowser (install.ps1)
are reached only via the explicit --ensure browser / -Ensure browser
on-demand mode, itself only triggered by an actual browser-tool call's
lazy-install fallback or `hermes acp --setup-browser`. agent-browser
already resolves via npx in that same fallback before ever reaching
these scripts, so eagerly npm-installing a second, separately
version-pinned copy here was redundant and an extra credential/
supply-chain surface for a path npx already covers. Chromium
acquisition for this on-demand path is now deferred entirely to
_maybe_autoinstall_chromium's existing lazy fallback. camofox's
install and system-browser detection/configuration are unaffected.
install.ps1 also drops the now-dead -SkipChromium switch, confirmed
unused at its one call site.
Full rewrite of test_browser_npx_warmup.py for the Popen-based
credential-scrubbing, PATH-propagation, and process-tree-kill rework:
argv shape, env scrubbing, PATH merge for managed-only npx, POSIX
process-group creation, Windows CREATE_NEW_PROCESS_GROUP, whole-tree
kill (not just the PID) on timeout with a bounded post-kill drain, and
_kill_process_tree's own POSIX/Windows/failure paths directly.
Also fixes test_windows_subprocess_no_window_flags.py's matching
regression test, which still mocked subprocess.run and a shutil.which
signature that didn't accept the path= kwarg _resolve_npx_bin's
extended-path rung now passes; its creationflags assertion becomes a
bitwise check since Windows now ORs CREATE_NEW_PROCESS_GROUP in
alongside the console-hiding flag.
Root package.json still owns devDependencies (the shared ESLint flat
config every workspace's eslint.config.mjs imports) even though
agent-browser and @streamdown/math were already removed from root
dependencies. The scoped `npm ci --workspace ui-tui --workspace web`
prunes them the same way it used to prune those; --include-workspace-root
protects them without reintroducing apps/desktop into the install.
- --ignore-scripts on every real npx agent-browser invocation.
AGENT_BROWSER_NPX_SPEC is a floating ^0.26.0 range, not an exact
pin, and none of these sites passed it (unlike install.sh/
install.ps1's own npm install of the same package). Verified against
the real CLI: `npx --ignore-scripts --prefer-offline -y
"agent-browser@^0.26.0" --version` resolves cleanly on npm
11.19.0/node 26.
- _resolve_npx_bin() now checks the Hermes-managed/extended search
before a bare ambient PATH lookup, validating each candidate with
node_tool_runnable before trusting it — a bare PATH-first lookup let
a broken system npx shadow a healthy managed one with no recovery.
- warm_agent_browser_npx_cache() now runs a credential-scrubbed,
PATH-propagated environment (matching every other agent-browser
subprocess spawn) instead of inheriting the full parent environment
including every provider/gateway credential Hermes holds, and kills
the whole process tree (not just the top-level npx PID) on timeout
via the new _kill_process_tree helper, since a surviving descendant
can otherwise hold a capture pipe open past the nominal deadline.
_browser_available()'s npx rung was missing the bare-npx-on-Termux
guard its sibling probes (dep_ensure, nous_subscription) already
apply, so it could report the browser probe available on Termux when
local mode would actually reject the bare npx fallback and fail on
first use.
Also adds argv-level coverage for the two real npx launch sites
(_run_browser_command, _run_chrome_fallback_command) and an
end-to-end test proving _find_agent_browser's lazy-install fallback
and ensure_dependency("browser")'s npx check terminate without
recursion.
The tools.browser_tool import-failure fallback in _has_agent_browser
dropped the Windows-installer managed-PATH probe and replaced a
PATHEXT-aware shutil.which lookup with a bare Path.exists() check,
reintroducing the .cmd-shim miss that probe was added to fix.
Both probes only checked PATH and node_modules, so they disagreed with
`hermes doctor` on npx-only installs (#43564): doctor --live reported
the browser probe unavailable, and ensure_dependency("browser") could
shell out to install.sh on installs doctor already reports healthy.
Git-clone installs resolving agent-browser via bare npx floated latest
with no integrity check, while install.sh/install.ps1 installs stayed
pinned to ^0.26.0. Pin the npx spec to match. Also extract the
"npx agent-browser" sentinel comparison (6 call sites across two
packages) into a named constant/predicate, fix a PATH-priority
inversion where a broken system npx could shadow a healthy
Hermes-managed one at the two real npx launch sites, and stop
`hermes doctor --fix` from counting a bonus npx cache warm as a fixed
issue on an otherwise-healthy run.
_run_npm_watching_for_engine_failure routes capture_output=False npm
invocations (the path _update_node_dependencies always uses) through
subprocess.Popen instead of subprocess.run. The
TestUpdateNodeDependencies mocks still patched subprocess.run, so they
fell through to the real, conftest-guarded Popen and tried to exec a
nonexistent /usr/bin/npm.
warm_agent_browser_npx_cache() spawns a resolved npx.cmd via
subprocess.run with a list arg and no shell=True, which Windows still
routes through cmd.exe. Without creationflags=windows_hide_flags(),
that can flash a console window during hermes update/doctor --fix,
same as the existing agent-browser subprocess spawn elsewhere in this
file already guards against.
Adds a regression test to the cross-cutting Windows no-window-flags
audit suite so a future refactor can't silently drop the flag again.
_find_agent_browser's extended-PATH branch now calls
shutil.which(name, path=extended_path), which broke two
post_setup_gating tests mocking shutil.which with name-only lambdas.
Update those mocks and two similarly-shaped chromium test mocks that
were latent landmines, and add coverage for cascade branches (local
node_modules/.bin, validate=False paths, and
_agent_browser_candidate_present) that had none.
The truthful per-provider readiness work (#67201) gates the desktop
Capabilities panel on _has_agent_browser, which only probes PATH and
node_modules/.bin. Now that agent-browser is no longer a root
package.json dependency (#43564), npx-only installs report needs_setup
in the panel while the browser tools themselves resolve fine at
runtime — and existing installs flip to needs_setup as soon as a
hermes update prunes node_modules.
Mirror the local-CLI tail of check_browser_requirements: resolve via
_find_agent_browser(validate=False), honor the Termux bare-npx
carve-out, and keep the old probe as the import-failure fallback.
Existing shutil.which test stubs gain the real signature so the
cascade's path= keyword calls don't break them.
`hermes update` was pruning root-level Node dependencies (agent-browser)
because npm ci always wipes and reifies node_modules according to its
active filter -- no root-first/workspace-first ordering or flag
combination (--workspaces=false, --include-workspace-root, etc.) can
reliably keep a root-only package.json dependency from being pruned by
a subsequent workspace-scoped npm ci. Confirmed empirically and via
npm/cli source (isArboristCmd hardcodes includeWorkspaceRoot=false for
ci/install), so no amount of install-order juggling fixes this for good.
Instead of chasing install order, remove the root-only dependencies
that made the npm step fragile in the first place:
- agent-browser is no longer a root package.json dependency. It
resolves lazily via `npx agent-browser` (tools/browser_tool.py
already had this as a fallback; it's now the primary path).
warm_agent_browser_npx_cache() is called fire-and-forget from both
`hermes update` and `hermes doctor --fix` to keep npx's cache warm,
preserving the "available before any session starts" property
agent-browser had as an eager dependency without re-entangling it
with the npm workspace graph.
- @streamdown/math moves to apps/desktop/package.json, where it's
actually imported (markdown-text.tsx, katex-memo.ts) -- it was
never used anywhere else and was subject to the same pruning risk.
- _update_node_dependencies() collapses to a single
`npm ci --workspace ui-tui --workspace web` call now that root has
no dependencies of its own to protect, and keeps its original spot
ahead of `_build_web_ui()` at both call sites in update_cmd.py --
with no root-only dependencies left to protect, there's no reason
for the Node refresh and the web build to run in any particular
order relative to each other.
- hermes_cli/tools_config.py's post-setup Chromium-install path and
hermes_cli/doctor.py's agent-browser check both now resolve through
the same PATH -> Homebrew/Hermes-managed-node -> npx cascade
(_find_agent_browser / _resolve_npx_bin) instead of hand-rolling
their own node_modules/.bin lookups, so they can't diverge from what
browser tools actually invoke at runtime.
- tests-js/package-json-lazy-deps.test.ts gets a lockfile-level check
mirroring the existing camofox one, so a future regression that
reintroduces agent-browser into package-lock.json fails this test
directly instead of relying on manual review to catch it.
Fixes#43564.
Simplify-code findings:
- _authenticated_json: replace manual header construction with
self._headers(include_tenant=False) — eliminates duplication with
_headers() and includes Content-Type consistently.
- _health_requires_credentials: replace getattr(exc, 'status_code')
with _status_code_from_error(exc) for consistency with the existing
error-classification utility. Drop the fragile string-matching
fallback — _parse_response always sets status_code on
_OpenVikingHTTPError, so 401/403 check is sufficient.
- Relax test header assertions to check presence/absence of specific
headers rather than exact dict equality, so they survive the
header-construction refactor.
Hosted OpenViking (Volcengine) rejects anonymous GET /health with
AuthenticationError, which made the provider look unhealthy and silently
disabled automatic memory mirroring. Keep the anonymous probe first for
identity safety, then retry once with the configured API key only when
the server demands credentials.
Fixes#78410
OpenCode identifies clients by request headers, the same way OpenRouter
does. Our opencode-zen and opencode-go profiles never set any, so every
request went out with the OpenAI SDK default "OpenAI/Python x.y.z"
User-Agent and OpenCode had no way to tell the traffic was Hermes Agent.
Two changes:
- Add HTTP-Referer, X-Title, and a HermesAgent User-Agent to both
OpenCode profiles through profile.default_headers, the same path
Fireworks uses. This covers chat_completions, codex_responses,
auxiliary clients, model switches, and the models catalog fetch.
- Merge the same headers in build_anthropic_client for opencode.ai
base URLs. The Anthropic Messages route (Claude on Zen, MiniMax and
Qwen on Go) builds its client there and never sees profile headers.
Verified against the live Go relay with a real key. Both wire formats
return HTTP 200 and the requests now carry X-Title "Hermes Agent",
HTTP-Referer, and User-Agent HermesAgent/0.20.0.
Live verification (gpt-5.6 @ api.openai.com) proved the Responses server
renders NOTHING placed before a replayed compaction checkpoint: a fact
stated in a pre-checkpoint input item is invisible to the model, while the
same item after the checkpoint recalls perfectly. Hermes was replaying the
full pre-checkpoint transcript anyway — dead upload weight, and worse, every
plaintext user ask from before the boundary silently vanished from the
model's view, surviving only inside the opaque server summary. That is the
goal-drift failure mode reported against native compaction sessions.
Codex CLI never hits this because it rebuilds history client-side after
compaction, retaining user messages verbatim under a token budget. This
change is the wire-level equivalent: when a replayed checkpoint is present,
_chat_messages_to_responses_input restructures the input as
[newest checkpoint run] + [retained pre-checkpoint user messages,
newest-first within a 64K-token budget] + [post-checkpoint tail]
Histories without a checkpoint are returned unchanged, so non-native
sessions see a byte-identical wire.
Webhook agent runs default to the constrained hermes-webhook toolset
(web/vision/clarify) because payloads can carry untrusted third-party
content. That default is right for public webhooks but wrong for trusted
local pushes (e.g. an OOM monitor daemon that needs the agent to run
ps/free/py-spy): the only workaround was widening platform_toolsets.webhook,
which elevates EVERY webhook route at once.
This adds a 'toolsets' key on individual webhook route configs (static
routes in config.yaml and dynamic subscriptions in
webhook_subscriptions.json) that replaces the platform-level resolution
for that route only:
- BasePlatformAdapter.toolsets_for_source(): per-source override hook,
default None (no behavior change for any other platform).
- WebhookAdapter.toolsets_for_source(): maps the session chat_id
(webhook:{route}:{delivery_id}) back to its route config and returns
the route's toolsets list.
- GatewayRunner._resolve_enabled_toolsets_for_source(): shared resolver
used by both agent-run call sites; validates the override through the
SAME _get_platform_tools path as platform config, so unknown names and
platform-restricted toolsets (e.g. discord_admin) are dropped rather
than trusted.
Deliberately NOT exposed via 'hermes webhook subscribe': granting elevated
tools is a manual config edit only, so an agent-created subscription
cannot self-grant terminal at runtime.
Cache-safe: the toolset list is resolved before agent construction and is
constant for a route, so the per-session agent signature and frozen system
prompt are unaffected mid-conversation.
Follow-up to the salvaged #80489 substring-fallback removal: the
structured 401/403 branch still exited with a bare return, leaving
_running True — dead listener, healthy-looking is_connected(), gateway
never told (the zombie half of the bug, OOF-156 class). It now sets a
non-retryable mattermost_auth_error with token guidance and notifies
the gateway fatal handler.
Also: pytest.importorskip for aiohttp in the verifier probe file
(module-level import crashed collection in envs without the optional
dep), and probe fixtures updated for the escalation attributes.
Independent-verifier boundary probes for commit fdd1a11ac5, covering
cases the implementer's regression tests did not exercise:
- WSServerHandshakeError(status=403) also stops the loop (only 401 tested)
- WSServerHandshakeError(status=500) does NOT stop the loop (structured
check must not over-match on type alone)
- transient error containing the word 'unauthorized' (not digit substring)
now retries correctly
- 5 consecutive transient errors all retry, not just the first
Verified these 2nd/4th tests fail against the pre-fix baseline commit
(01a1037d1e) and pass against the fix (fdd1a11ac5), confirming they
have real signal.
The WS reconnect loop had a fallback check that looked for "401", "403",
or "unauthorized" as substrings anywhere in an exception's string form.
A transient error whose message happens to contain those digits (a proxy
body, a stack trace, anything) got treated as a permanent auth failure
and stopped reconnection for good.
I removed the substring fallback and kept only the structured check:
aiohttp.WSServerHandshakeError with status in {401, 403}. That's the only
signal that reliably means the server rejected our credentials.
Added two regression tests: one proving a transient error containing
"401" in its text still retries, and one confirming the existing
_closing early-return path is untouched by the removal.
Simplify-code finding: test hardcoded exit code 75 in string
assertion while already importing GATEWAY_SERVICE_RESTART_EXIT_CODE.
Use f-string interpolation so the assertion tracks the constant.
Follow-ups to the salvaged #80032 fatal-error escalation, closing the
gaps its review thread identified plus a sibling of the same class:
1. Partial-batch loss: _check_inbox now dispatches whatever the fetch
returned BEFORE escalating a failure — the early-return dropped
already-fetched messages whose UIDs were marked seen.
2. Seen-after-fetch: UIDs enter _seen_uids only after their fetch
returns a response, so a mid-batch connection failure leaves the
remaining UIDs eligible for the next poll. Per-message processing
moved to _parse_fetched_message behind a poison guard: a message
that fails parsing/auth-verification is marked seen, logged with
its UID, and skipped once — never an eternal crash loop.
3. Reconnect mail loss: connect(is_reconnect=True) restores the
account's seen-UID baseline from a class-level snapshot instead of
re-marking the entire mailbox seen — mail that arrived during an
outage is now processed after the reconnect the escalation triggers.
7 new regression tests.
_fetch_new_messages() wrapped the whole IMAP connect/login/select/search/
fetch sequence in a bare except that logged and returned an empty list —
indistinguishable from a genuinely empty inbox. The adapter never invoked
its fatal-error handler, so the gateway's reconnect/backoff/status
machinery never learned the mailbox was unreachable; outages lasted until
a manual restart.
Track fetch failure on the adapter and, when the poll loop observes it,
set a retryable fatal error (email_imap_fetch_failed) and notify the
gateway handler so the platform enters the reconnect queue just like a
startup connection failure.
Final-diff simplify/review pass findings on #83785:
- Consent gate (confirm_truncate -> 4029) now checked BEFORE target
resolution, restoring the pre-PR precedence: an unconfirmed submit
carrying truncation params refuses without paying the durable-transcript
read or heal-stamping live history dicts, and an unconfirmed out-of-range
ordinal returns 4029 (not 4018). Malformed params still refuse first
with 4004. Regression test added (spy DB asserts zero reads pre-consent;
mutation-checked against the previous commit).
- _coerce_truncate_ordinal generalized to _coerce_truncate_int(param_name):
the row_id branch was inlining the exact bool-guard + int() -> 4004
pattern the helper had just extracted.
- Deleted the dead user_indices re-read after _resolve_truncate_row_id
(heal mutates dicts in place; the filter output is identical) and the
duplicate range check that had deadened the pre-existing guard.
- Desktop: exported isVisibleUserMessage from use-prompt-actions/utils and
used it in visibleUserOrdinal / visibleUserIndexAtOrdinal /
rebindSurvivorRowIds — one predicate for the ordinal parity all three
depend on instead of three verbatim copies.
- Docs: programmatic-integration.md documents survivor_user_row_ids.
Review follow-up (StanleyStetson + egilewski on #83785/#83202): a successful
rewind's replace_messages(archive_dropped=True) re-inserts the surviving
prefix as NEW SQLite rows. Gateway memory picks up the fresh _row_id stamps
via lastrowid, but the Desktop's surviving bubbles kept their pre-rewind
ChatMessage.rowId — so a second rewind/edit/regenerate of an older surviving
turn sent a stale truncate_before_row_id and was (correctly) refused with
4018 until a transcript reload. Fail-closed stays untouched, per both
reviews; the fix is rebinding, not ordinal fallback.
Server: prompt.submit now returns survivor_user_row_ids (fresh post-rewrite
ids of surviving visible user turns, in visible-user-ordinal order) on both
the inline and compute-host paths whenever a durable truncation committed.
Desktop: runRewindSubmit surfaces the field; restore/edit/reload on both the
primary chat and session tiles rebind surviving user bubbles positionally
(same visible-user filter the ordinal math uses) and clear any rowId they
cannot rebind — a cleared id degrades to the ordinal path instead of a 4018.
Absent field (older gateway) leaves state untouched.
Tests: consecutive-rewind regression on a real SessionDB (stale id 4018s,
returned id succeeds; mutation-checked) + vitest for survivorRowIdsFrom /
rebindSurvivorRowIds (rebind, null-clear, past-end clear, hidden skip,
identity preservation).
Review cleanup on the #83202 salvage (findings from the 4-angle + 3-reviewer
passes, all verified against the diff):
- Extract _coerce_truncate_ordinal() and _reconcile_client_ordinal(): the
bool-check/int-coercion block was duplicated verbatim 3x and the 4030
ordinal-mismatch block 2x across the row-id/message-id/ordinal branches
(~90 lines of copy-paste with drift risk between the two durable branches).
- Delete target_idx (4 assignments, 0 reads — the cut uses
user_indices[ordinal]) and replace the stale inline user-indices
comprehension with the _history_user_indices helper it duplicated.
- Drop test_reproduce_row_id_truncation: a strict subset of
test_prompt_submit_truncates_by_row_id +
test_prompt_submit_refuses_ordinal_and_row_id_mismatch with weaker asserts.
- Collapse PR-introduced blank-line runs in the test file.
Behavior-preserving: error codes, messages, and log fields unchanged
(4004/4018/4029/4030 wording identical); full test_tui_gateway_server.py
suite green (549 passed).
The #83202 heal path zip-stamped _row_id onto live-memory dicts purely by
position whenever the durable and live lists had equal length, and the DB
fallback mapped durable user-ordinals onto live indices with only a bounds
check. Equal length is not proof of alignment: the durable copy is loaded
with repair_alternation=True (merges user;user pairs, collapses consecutive
assistants, drops orphan tool rows) while live memory is unrepaired and can
carry optimistic/marker rows — the two can coincide in length while
position-shifted. A misaligned stamp is sticky: it permanently attaches the
wrong durable id to a live dict and re-aims every later rewind (E2E probes
showed a wrong-content cut and a persisted alternation break).
_mem_db_pair_agrees() now gates both paths: the heal loop stamps only when
EVERY zip pair agrees on role, display-marker status, and (for addressable
user turns) content; the ordinal fallback verifies the mapped live turn
shows the durable target's content, else refuses via the existing
fail-closed 4018. Regression tests derived from the review probes (content
swap, role shift, repaired-merge ordinal shift); the misalignment guards
fail on the pre-fix code.
Surfaced during review of PR #83202 for #82959.
Address rewinds/edits via SQLite messages.id (truncate_before_row_id)
instead of shifting user ordinals. Resolve against in-memory stamps,
then durable session history when live turns drop _row_id; refuse
unknown durable targets with 4018 (no ordinal fallback) and 4030 on
ordinal/row_id mismatch. Stamp _row_id on insert, load row ids on
resume paths, send rowId from Desktop, filter renderer-synthetic ids,
and stop silently resending failed targeted edits without truncation.
Add production-shaped SessionDB tests for resolve and fail-closed paths.
Fixes#82959
The cherry-picked #79448 predated #85049's _classify_connect_exception,
so it added a parallel PrivilegedIntentsRequired branch ahead of the
classifier (plus its own _is_privileged_intents_required detector).
Fold the tailored guidance into the classifier's existing intents arm
instead: one classification path, one error code (discord_intents_required),
and the message now names exactly the intents Hermes requested (Message
Content always; Server Members only when username/role allowlists need it).
Wizard callout, docs corrections, and tests from #79448 kept as-is.
PrivilegedIntentsRequired is a Developer Portal config error; surface which
intents Hermes requested as a non-retryable fatal and teach setup/docs.
