Babysit
Stay on the PR after handoff until it's actually done. Being asked to babysit
IS the ask to poll — but report state changes only, no heartbeats, no
per-poll narration.
Loop
- Snapshot:
gh pr view <N> --json state,mergeable,mergeStateStatus,reviewDecision,statusCheckRollup,autoMergeRequest
plus gh pr checks <N>.
- Poll inside bounded shell loops (a single
for with sleep 30–60
between iterations), not one message per check.
- React by cause:
- CI never started → kick it:
git commit --allow-empty -m "chore: kick CI" && git push.
- Red caused by this branch → fix it (the
pr-ready loop), push,
resume watching on the new SHA.
- Flake / infra red → rerun the failed jobs; repeat until green. Note
the flake in one line with the run link.
- New review threads → handle per
pr-ready (fix or reply, verify
resolved via the forge API), resume.
- Repeat until done. A push or rerun is progress, not an exit.
Merging
Arm automerge only when the ask says so — "set to automerge", "make CI
green", or any mention of merging. A plain "babysit" / "watch it" ends at
green with threads resolved: report, don't merge.
CI quirks
gh run rerun refusing with "already running" → cancel the run first,
then rerun.- A cancelled run showing "no checks reported" is pending, not red — wait
for it to re-report before calling it either way.
- Rollup gates ("All required checks pass") go red because a leaf did —
diagnose the leaf failure, never the gate.
Done when
Re-query the forge — don't trust that a push went green or a rerun stuck.
Merged, or every check green with no unresolved threads. Fail closed: any
red or open thread means keep watching. Wrap up with the PR/MR link and what
the watch consumed — reruns used, kicks, fixes pushed.
Scope
- In: watching an open PR, kicking stalled CI, rerunning flakes, small
branch-caused fixes, late review threads.
- Out: opening or refreshing the PR (
pr-update, cpr), full
rebase/red-CI overhauls (pr-ready), other people's PRs (pr-triage),
merging unasked.
