Babysit a PR

Keep one existing pull request current until its required checks and review bots finish on the latest head commit. The user's original goal remains the scope.

Start with the current PR

Resolve the PR from the request or current branch. Record its URL, base branch, head commit, latest push time, required checks, and review state. Confirm the local checkout matches its head before editing. If several PRs fit, ask which one to watch.

Watch and respond
