## PR Notes
This PR adds a project-scoped `babysit-pr` skill for ongoing PR
monitoring (CI, reviews, mergeability).
Simply invoke this skill after creating a PR, and codex will do its best
to get it to a mergeable state:
### What the skill does
* Fixes CI failures related to the PR
* Retries CI failures due to flaky tests
* Addresses code review comments if it agrees with them
* Addresses merge conflicts on main branch
### How the skill works
- Polls PR status on a loop (CI checks, workflow runs, review activity,
mergeability, and review decision).
- Detects new review feedback (including inline comments and automated
Codex review comments) and prompts/handles follow-up work.
- Distinguishes pending vs failed vs passed CI and identifies likely
flaky failures.
- Can retry failed checks/workflows when appropriate.
- Prioritizes actionable code review feedback over flaky CI retries (to
avoid rerunning CI on a SHA that is about to be replaced).
- Continues monitoring after fixes are applied and pushed, rather than
stopping after a progress update.
- Uses a slower backoff polling cadence once CI is green, while still
watching for new review feedback or state changes.
- Treats required review/approval as a blocking condition and keeps
watching until the PR is actually merge-ready (or merged/closed, or
human intervention is needed).
### Intended outcome
Keep the PR moving with minimal manual babysitting by continuously
watching for CI failures, reviewer feedback, and merge blockers, and
responding in the right order until the PR is ready to merge.
