Coatue FR (Frank Long): jobs delivering into shared channels publish
engine failure notices ('⚠️ Cron X failed…') to those channels with no
opt-out. Adds an optional per-job failure_deliver field sharing
deliver's grammar: on failure, targets resolve from failure_deliver
when set (local = structural silence; state still recorded in
last_status/last_error/run history). Success delivery is unchanged;
absent field = today's behavior byte-for-byte.
Honored by every failure-category engine notice: the run_job failure
summary (+streak nudge), the escaped-failure retry path, drift-skip and
blocked-config alerts (composed into the same delivery), and the
gateway-shutdown interrupted-run notice (_notify_interrupted_cron_jobs).
Surfaces: cronjob tool create/update (same bot-chat validation as
deliver; '' clears on update), hermes cron create/edit
--failure-deliver, docs tip in automate-with-cron.
Existing fake_deliver test doubles gained **kwargs for the new
for_failure keyword — signature-compat only, no behavior change.
A recurring job that fails at the scheduler layer - an exception escaping
run_one_job's body before the agent is ever constructed - has delivered a
failure alert since 4668750fa. It has never carried the repeated-failure
review nudge the normal agent-failure delivery carries: the nudge (#80752,
2026-08-06) predates that second delivery site by eight days and only ever
composed the first one.
The streak itself is layer-agnostic. mark_job_run increments failure_streak
for an escaped failure exactly as it does for an agent failure, and the
escape handler calls it. So the counter climbs correctly and shows up in
`hermes cron list`, but the chat message that spends it is unreachable for a
job whose failures ALL escape - a half-applied update leaving a bad import,
a provider client that cannot construct. Those are precisely the failures
that repeat identically on every tick, so the operator gets the same one-line
error every 10 minutes indefinitely and is never told the automation itself
is worth reviewing or pausing.
Compose the nudge at the escape handler's delivery exactly as the normal
path does. It stays config-gated and threshold-gated by the same helper, so
a first-time escaped failure reads exactly as it did before.
Docs said the streak counts "runs where the agent failed", which is what the
reporter read and reasonably concluded their failures were out of scope. The
counter never worked that way; correct the sentence to match the code.
Tests: two cases on the escaped-failure delivery path - streak at threshold
appends the nudge (fails on the unfixed handler with the bare summary), and
streak below threshold delivers the unchanged one-liner, so the guard also
proves the nudge is not unconditional. The existing nudge tests only ever
exercised the helper in isolation, which is why the second delivery site
could be added without it.
Fixes#88655
- claim_job_for_fire returns the atomically claimed snapshot with a unique
fire owner; heartbeat_fire_claim renews the lease; mark_job_run fences
terminal writes by expected_fire_owner so a stale worker cannot record
over a replacement claim.
- run_one_job heartbeats the fire claim and forwards a combined cancel
event (ownership loss OR external cancel) into run_job; the agent path
is interrupted cooperatively and script-based jobs (no_agent + pre-run
scripts) are hard-stopped with a process-tree kill (POSIX killpg
SIGTERM then SIGKILL for surviving group members; Windows
taskkill /T /F), with a bounded pipe drain so a SIGTERM-ignoring
descendant cannot wedge the worker on communicate() EOF.
- Shutdown interruption is scoped to the exact execution token instead of
the bare job ID, so a replacement run of the same job never consumes a
stale interrupted flag.
- fire_claim_fence serializes save/deliver side effects per profile+job
with a cross-process flock; remove_job prunes the fence-lock entry.
- Preserves upstream BaseException terminal recording (#73973),
completed one-shot retention (#80624), blocked_config preflight
(T1-26), and the advance_next_runs batch on top of current main.
Validate a job's configuration BEFORE any agent machinery is constructed:
- missing provider API key (AuthError from a read-only
resolve_runtime_provider probe; skipped when a fallback_providers chain
is configured, since auth-fallback may rescue the run)
- attached skill not ready (skill_view readiness_status=setup_needed —
missing required env vars / commands / credential files)
- delivery platform unknown or unconnected (deliver=local/origin/all are
never checked; gateway-config load failures fail open)
On a failing check run_job returns a [blocked_config]-marked error without
constructing AIAgent/MCP/etc, so a misconfigured job never burns an LLM
call. run_one_job records last_status='blocked_config' and delivers the
alert exactly ONCE across ticks (persisted preflight_alerted bit — the
alert-once shape from the #73506 dead-pin auto-pause); the next healthy
run clears the marker so a future break re-alerts. Every preflight check
fails open: only an affirmative misconfiguration verdict blocks.
Config: cron.preflight (default true); `cron.preflight: false` restores
the old fail-during-run behavior. Documented in the cron user guide and
config defaults.
mark_job_run gains an optional status= override (unblocked call shape
unchanged) and drops preflight_alerted on any successful run.
Tests: tests/cron/test_preflight_config.py (blocked_config + no agent +
single alert across two ticks, healthy job unaffected, recovery clears
dedup, fallback-chain rescue, opt-out restores old behavior, skill
readiness miss, unknown delivery platform, deliver=local never loads
gateway config). Full tests/cron/ + cronjob tool suite green (525 tests).

Salvaged from PR #57342 by @liuhao1024 (with the injection-scan half
from PR #57360 by @ghedeselmabot): cronjob(action='run', prompt=...)
silently discarded the prompt argument — per-run context never
reached the spawned cron session.
The prompt is now threaded as extra_prompt through the whole chain
(cronjob run action → _try_dispatch_background_run/_execute_job_now →
_run_claimed_job → run_one_job → run_job → _build_job_prompt) and
appended to the stored prompt under a '## Run Context' header for
that single fire only — never persisted to the job definition. It
passes the same strict _scan_cron_prompt injection scan as stored
prompts before firing, and works identically on the background and
sync fallback paths.
Test fakes across tests/cron/ updated to accept the new kwargs
(sibling-test blast radius from the signature change).

The scheduler's pre-dispatch loop called advance_next_run per due job —
one full load_jobs() + one full save_jobs() of the jobs file each — so
N due jobs cost N reads + N writes of the whole file (gateway-restart
catch-up or co-scheduled bursts). advance_next_runs() does one load +
at most one save for the whole due set with identical per-job semantics;
advance_next_run() is now a thin wrapper over it.
Measured (50 due recurring jobs, real jobs file): 107.9 ms -> 2.5 ms
(45x; 50 loads + 50 saves -> 1 + 1).
Tests: batch advances recurring and skips one-shots, single load + save
I/O pin (fails pre-fix — no such function), no save when nothing
advances, and per-job wrapper semantics unchanged. Related: #60946 and
#75833 both restructure this loop's call site for correctness — neither
addresses the I/O cost, and this batch primitive composes with either
dispatch design; happy to rebase onto whichever lands first.
Fixes#73973.
A finite one-shot whose dispatch was claimed (claim_dispatch increments
repeat.completed BEFORE execution) but whose run died before mark_job_run
was left permanently wedged: completed==times, last_run_at null, state
'scheduled'. The run-claim TTL blocked re-dispatch, and once it expired
the dispatch-limit guard silently removed the job with no output and no
error.
Two complementary fixes:
- cron/scheduler.py run_one_job: the outer handler now catches
BaseException, not just Exception. The inner run_job handler re-raises
CancelledError/KeyboardInterrupt/SystemExit after agent teardown, and
none of those are Exception subclasses, so the outer 'except Exception'
missed them and mark_job_run(False) was never called. Failures are now
recorded first (mark_job_run + finish_execution, each independently
guarded), then non-Exception BaseExceptions are re-raised to preserve
teardown semantics. Plain Exceptions keep the existing behavior
(recorded, return False, no re-raise). Empty str(e) (bare
CancelledError) falls back to the exception class name.
- cron/jobs.py: when either removal site (claim_dispatch or the
get_due_jobs dispatch-limit guard) drops a one-shot whose claimed run
never completed (last_run_at null), _write_wedged_oneshot_diagnostic
now writes an operator-visible .md into cron/output/<job_id>/ instead
of vanishing silently. Best-effort: diagnostics can never break the
removal. No diagnostic when last_run_at is set (normal completion
race).
Issue #65773: run_one_job installs a <home>/.env secret scope around every
job; before c758ded6d (#69057) an installed scope was authoritative even
with multiplexing off, so provider keys injected only via the process
environment (container env vars, systemd Environment=) resolved to empty
inside cron and every provider call went out with the no-key-required
placeholder -> HTTP 401, while interactive turns kept working.
The fix landed in agent/secret_scope.py (scope-miss fallthrough to
os.environ when multiplex is off) with unit tests at that layer only.
These two tests pin the end-to-end contract where the bug actually
surfaced - cron's run_one_job:
- env-injected key resolves during run_job with multiplex OFF (fails on
pre-fix code, verified by mutation against c758ded6d~1)
- .env value still wins when both sources define the key (precedence)
Implementation-agnostic: passes whether the fix is the get_secret
fallthrough (main today) or a multiplex guard at the installation site
(the approach in #65801/#65802/#73037).
Defense-in-depth alongside the interpreter-shutdown guard: run_job closed
the cron agent's async resources (agent.close + cleanup_stale_async_clients)
in its finally block BEFORE run_one_job called _deliver_result, so a live
delivery could race a torn-down async client. run_job now accepts an optional
defer_agent_teardown holder; when set it hands the live agent back instead of
closing it, and run_one_job tears it down (via the extracted _teardown_cron_agent
helper) only AFTER delivery — in a finally so a failed run never leaks. Default
path (holder=None) is unchanged, so every existing caller keeps inline teardown.
Reorder approach based on #58777 by @LavyaTandel; reworked to keep a single
delivery site in run_one_job and add regression coverage.

Asserts the behavior contract that run_one_job installs a profile secret
scope around run_job under multiplexing (so resolve_runtime_provider's
get_secret does not fail-close with UnscopedSecretError) and tears it
down afterward. Mutation-verified: fails on unmodified main with the
exact UnscopedSecretError, passes with the fix.
Phase 4A. Factor tick's per-job closure (_process_job: execute → save →
deliver → mark) into a module-level run_one_job(job, *, adapters, loop,
verbose) so the external Chronos provider's fire_due (Phase 4D) reuses the
IDENTICAL body — no duplicated correctness. tick's _process_job is now a thin
wrapper calling run_one_job; the pool/in-flight-guard/contextvars dispatch
logic is unchanged.
run_one_job fires ONE given job; it does NOT decide due-ness, claim, or compute
next_run (tick advances next_run_at under the file lock; an external provider
claims via the store CAS in Phase 4C). Pure refactor, no behavior change.
TDD: test_run_one_job.py characterizes the sequence through tick() first
(test_tick_process_job_sequence, passed pre-extraction), then unit-tests the
helper directly: success sequence, [SILENT]→skip delivery, empty-response soft
failure (#8585), failed-job-still-delivers, exception→mark-failed.
Verified: tests/cron/ 459 passed (was 453 + 6 new); tick behavior unchanged.
