Workflow source needed

PR #3077 needs either a linked GitHub issue or one valid non-issue Workflow Source before PR metadata automation can manage it safely.

Please do one of:

  • Add <!-- meta:issue:123 --> or a normal Closes #123 / Related to #123 line.
  • Check one Workflow Source option in the PR body.
  • Add a hidden marker such as <!-- workflow-source:local_request -->, <!-- workflow-source:manual_remote -->, <!-- workflow-source:review_followup -->, <!-- workflow-source:sync_campaign -->, or <!-- workflow-source:dependabot -->.
  • Add a workflow source label such as workflow:source-direct-pr, workflow:source-local-request, workflow:source-review-followup, workflow:source-sync, or workflow:no-automation.

Once a valid source is present, this warning will not be reposted.

Review Change Stack

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your recent review volume is higher than typical usage, so adaptive limits are currently applied.

Next review available in: 43 minutes

Your organization has reached its usage spending cap. Adjust your spending cap in the billing tab.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

Keepalive state parsing now requires a marked summary comment authored by an approved bot account. The change is applied to both the primary script and consumer-repository template, with tests and documentation updated accordingly.

Changes

Keepalive trust boundary

Layer / File(s) Summary
Trusted comment filtering
.github/scripts/keepalive_challenge_due.js, templates/consumer-repo/.github/scripts/keepalive_challenge_due.js
Both scripts define and export isTrustedKeepaliveStateComment. State parsing now ignores comments without the summary marker, approved author login, or bot user type.
Trust boundary tests and guidance
.github/scripts/__tests__/keepalive-challenge-due.test.js, docs/keepalive/Agents.md, docs/keepalive/GoalsAndPlumbing.md
Tests cover trusted bot comments and forged or incomplete markers. Documentation identifies the approved bot accounts and excludes user and generic workflow-bot comments.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: 🟡 Moderate · up to 767ce

The change restricts keepalive state to dedicated bot-authored comments, but the current documentation gives conflicting three-failure recovery instructions and describes a manual reset path that cannot produce accepted state. This could lead to skipped recovery actions, so the recovery contract should be made consistent before merging.

1. **PR body is the contract**: Auto-pilot writes structured tasks into the PR body. Keepalive reads these tasks via the task appendix. If the PR body format changes, both must be updated together.

2. **Labels are handoff signals**: Auto-pilot applies the selected registry-backed `agent:<name>` label (for example, `agent:codex` or `agent:claude`) and keepalive activates. Every non-transient run/fix failure records automation-owned recovery state and explicitly dispatches a bounded retry through the active workflow (`agents-keepalive-loop.yml` in the root lane or `agents-81-gate-followups.yml` in consolidated consumers). A failed direct dispatch defers that durable lease for the hourly sweep instead of adding a sticky `agent:retry` label; after 3 failures, the current strategy pauses for the same hourly recovery sweep. It does not infer that a human is required. Each hourly sweep wakeup bypasses state debounce so current state is re-evaluated, while ordinary wakeups retain completed-runner debounce. A possible authority boundary enters an independent scheduled challenge whose durable fingerprint is derived only from the routed agent's registry-backed required credentials, shared registry authority credentials, finite permission targets, and HTTP 401/403; arbitrary runner text is never copied or persisted. Only the sweep passes a valid HMAC-signed claim using `KEEPALIVE_AUTHORITY_SIGNING_KEY` and binding that fingerprint to the repository, PR, random nonce, and exact sweep run/attempt; that signed due claim alone may bypass runner debounce and force-dispatch. A generic retry or another workflow sharing `github-actions[bot]` cannot confirm the challenge. Missing signing material fails closed to an ordinary non-forced recheck. A matching second failure may record the projected human action and apply `needs-human`. A different auth failure stays automation-owned and is challenged again on the next sweep.

Align the three-failure recovery contract.

This text says that the strategy pauses for the hourly recovery sweep after three failures. docs/keepalive/GoalsAndPlumbing.md line 87 says that keepalive first dispatches one forced recovery lease.

Select one behavior and state it consistently in both documents. The current conflict can cause an operator or future workflow change to omit the forced recovery dispatch.
