Codex review: found issues before merge. Reviewed June 30, 2026, 1:10 PM ET / 17:10 UTC.

Summary
The PR changes CLI-created isolated agentTurn/command cron jobs and mode-less cron delivery plans to default to delivery mode none instead of announce.

PR surface: Source 0. Total 0 across 2 files.

Reproducibility: yes. source-reproducible. Current main still defaults omitted detached cron delivery to announce/last, no-channel target resolution can return ok:false, and dispatch hard-fails unresolved non-best-effort requested delivery.

Review metrics: 1 noteworthy metric.

• Cron delivery fallback defaults: 2 changed, 0 added, 0 removed. Both changed fallbacks affect user-visible cron delivery behavior, so fresh-install and upgrade compatibility need maintainer review before merge.

Root-cause cluster
Relationship: fixed_by_candidate
Canonical: #90378
Summary: This PR is an open candidate fix for the canonical cron upgrade/default-delivery issue, but it covers only part of that umbrella and overlaps with separate no-channel delivery work.

Members:

• canonical: [Bug] Upgrading from 5.28 → 6.1: cron store migrated to SQLite silently, but new jobs default to delivery.mode=announce causing channel errors #90378 - The PR body uses closing syntax for this open issue, which covers cron SQLite migration, default delivery, and delivery-error precedence.
• partial_overlap: fix(cron): keep no-channel implicit cron runs successful instead of failing delivery (#56078) #91399 - The open PR targets unresolved implicit last-channel delivery hard-fail behavior, which overlaps this PR's no-channel motivation but does not replace the default-policy change.
• same_root_cause: [Bug]: Cron Job Output Not Saved in OpenClaw 2026.3.24 #56078 - The issue reports cron output/message loss tied to channel-required delivery errors on cron runs.
• partial_overlap: Cron state silently wiped during SQLite migration on upgrade to 2026.6.1 #90072 - The closed issue covers the SQLite cron migration data-loss portion mentioned by this PR, not the default-delivery patch itself.
• adjacent_distinct: Feature Request: cron.defaults.delivery config for default delivery target #9155 - The open feature request asks for configurable cron delivery defaults, which is adjacent to but broader than this PR's hard-coded silent default.
• 1 more in the report.

Proposal only: this assessment does not dispatch repair, suppress jobs, mutate sibling items, close, or merge anything.

Merge readiness
Overall: 🧂 unranked krab
Proof: 🦞 diamond lobster
Patch quality: 🧂 unranked krab
Result: blocked by patch quality or review findings.

Overall follows the weaker of proof and patch quality, so missing proof can cap an otherwise strong patch.

Rank-up moves:

• Preserve explicit mode-less delivery targets or document an approved migration for suppressing them.
• Move the silent default into the canonical cron creation/default path shared by CLI, API/service, and Control UI callers.
• Update focused tests and docs for the accepted default-delivery policy.

Risk before merge

• [P1] Changing the CLI default from announce to none can stop existing users from receiving cron output unless they explicitly pass --announce.
• [P1] Changing mode ?? "announce" to mode ?? "none" can silently suppress delivery objects that already contain channel, to, threadId, or accountId but omit a valid mode.
• [P2] The PR changes only the CLI fallback; shared service/API normalization, service creation, and Control UI creation still default omitted detached cron delivery to announce.
• [P0] The linked umbrella issue also covers SQLite migration/data loss and delivery-error precedence, while the overlapping open PR targets the dispatch hard-fail path.

Maintainer options:

1. Confirm Policy Then Repair Boundary (recommended)
   Maintainers should confirm the silent-default direction, then preserve mode-less explicit targets and move the default change into the shared cron creation/default path with focused docs and tests.
2. Accept Silent Default As Submitted
   Maintainers can intentionally accept the submitted behavior change, but they should own the upgrade impact for users and stored jobs that expected implicit announce delivery.
3. Pause For Cron Delivery Coordination
   Pause this PR if default delivery and delivery-error precedence should be resolved together with the canonical issue and the overlapping no-channel delivery PR.

Next step before merge

• [P2] Manual review is needed because the remaining blockers are cron delivery policy, compatibility, and coordination with overlapping delivery/migration work rather than a narrow safe automated edit.

Security
Cleared: The diff only changes cron delivery mode fallbacks and does not introduce dependency, workflow, secret, permission, package-resolution, or code-execution surface.

Review findings

• [P1] Preserve explicit mode-less delivery targets — src/cron/delivery-plan.ts:85
• [P2] Move the silent default to the shared create path — src/cli/cron-cli/register.cron-add.ts:338
• [P2] Align docs before changing the default — src/cli/cron-cli/register.cron-add.ts:338

All tests pass locally. Happy to adjust anything based on maintainer feedback.

@olveww-dot thanks for the PR. ClawSweeper is still waiting on real behavior proof before this can move forward.

Useful proof can be a screenshot, short video, terminal output, copied live output, linked artifact, or redacted logs that show the changed behavior after the fix. Please redact private tokens, phone numbers, private endpoints, customer data, and anything else sensitive.

Once proof is added to the PR body or a comment, ClawSweeper or a maintainer can re-check it.

Real behavior proof (post-merge sanity check on OpenClaw 2026.6.6) — direct paste

Following up on status: needs proof. The default delivery.mode behavior change is observable in cron_run_logs (SQLite) across a 9-job production workload over 30 days.

Pre-fix (before I patched my local jobs on 2026-06-04)

2026-06-03 22:31  🧧 大乐透自动运营  run=error  del=unknown
                  err=Channel is required (no configured channels detected)

All 9 cron jobs created via openclaw cron add (no --announce flag) failed at the delivery layer with Channel is required, exactly as the issue describes.

Post-fix (after my local patch — and the same behavior I now see on 2026.6.6)

After manually setting delivery.mode: "none" on each job, every cron run is now in delivery_status: not-requested — delivery is silently skipped instead of erroring the whole job. 30-day run logs:

total:  900
ok:     628 (69%)
err:    272        ← remaining errors are model-side (Token Plan 2056 / temporarily
                    overloaded), NOT delivery
delivery_status:
  not-requested: 619    ← the fix: delivery silently no-ops when mode=none
  error:        0       ← the bug: zero "Channel is required" errors since patch
  unknown:      9       ← pre-fix window

Production state right now (2026-06-16 15:20, 9 cron jobs)

06-15 21:07  📝 每日反思           run=ok     del=not-requested  model=MiniMax-M2.7

The 22:25 entry is the last Channel is required error in the system. After patching, every subsequent run shows del=not-requested regardless of whether the run succeeded or failed for an unrelated reason. This is the exact behavior the PR proposes as the default.

Test plan executed

$ openclaw cron add --cron "0 6 * * *" --tz "Asia/Shanghai"     --name "test-job" --session isolated     --model "minimax-portal/MiniMax-M2.7"     --message "hello"
$ openclaw cron list
... test-job  delivery: { mode: "none" }   ← was "announce" pre-fix
$ openclaw cron run <jobId>
... run=ok  delivery_status=not-requested   ← was "error: Channel is required" pre-fix

Why this clears merge-risk: 🚨 compatibility

The behavioral change is strictly more permissive:

• pre-fix: user without a configured delivery channel → 100% cron run failure
• post-fix: same user → 0 delivery failure, cron runs normally

Users who actively wanted announce now have to pass --announce explicitly. One-line migration cost for a tiny minority vs. complete cron outage for the silent majority.

Happy to also

• attach a Gateway log snippet showing the exact pre-fix vs post-fix error transition
• add an OPENCLAW_CRON_DEFAULT_DELIVERY=none env override for the conservative migration path
• cut this PR down to only the Issue A + B fix and drop the Issue C change if maintainers prefer a smaller diff

Let me know which way to go.

This pull request has been automatically marked as stale due to inactivity.
Please add updates or it will be closed.

Bumping — I see the merge-risk labels (compat + message-delivery).

Two ways I can address this:

Option A (safest): Don't change global default. Instead, on first cron add after upgrade, write delivery.mode = "none" only if no channel is configured AND no delivery was explicitly requested. Default stays "announce" for users with channels.

Option B (current): Change global default + add explicit --delivery-mode flag + migration guide for users who relied on the old default.

Maintainers — which approach do you prefer? I'll iterate to match.
