work-on-issue-loop

# work-on-issue-loop Drive an issue from "validated" to "PR reviewed to convergence" without stopping in between. Step 1 implements the issue and opens the PR. The review cycle after that is fix-pr-review-loop's convergence loop, run against the new PR. fix-pr-review-loop owns the loop mechanics (bot selection, preflight, wait procedure, stop conditions, cycle cap, resolution); this skill adds the implementation step, the follow-on issue sweep, and its own terminal state for a run that never produces a PR. Use fix-pr-review-loop directly when there is no issue to implement first, just an existing PR to drive to approval. ## Input - Nothing — default to the issue just validated this session, else the latest open issue (`gh issue list --limit 1`). - `#<N>` / `<N>` / full URL / `owner/repo#N`. ## Steps ### 1. Implement, open the PR, and trigger the first review Invoke the `work-on-issue` skill for the issue (Skill tool, `skill: work-on-issue`). It implements the fix in an isolated worktree, verifies it, commits, pushes, and opens the PR (`Closes #<N>`). It does **not** request review; that is this loop's job. **Gate on its outcome before continuing — work-on-issue can legitimately stop early:** - **Stopped with no PR** (issue already closed, an existing PR already addresses it, wrong repo checked out) → there is nothing to drive; stop and relay its report. - **PR opened** → capture the PR number/URL and the branch, then trigger the first review yourself.
