fix-pr-review-loop

# fix-pr-review-loop Drive an already-open PR from "has review feedback" to "reviewed to convergence" without stopping in between: resolve the latest review (fix-pr-review), wait for the bot's re-review, and repeat. Past 5 cycles the bar for "done" relaxes — any LGTM ends the loop — so a PR with recurring minor findings doesn't get fix-pr-review'd forever. This skill owns the convergence loop; work-on-issue-loop delegates to steps 2 through 4 here after it opens a PR, then writes its own report step that reuses step 5's terminal-state table with two named deltas (its own "no PR" row, plus the follow-on issue URLs it files). An edit to step 5's table therefore needs a matching edit in work-on-issue-loop step 4. ## Input - Nothing — default to the PR for the current branch (`gh pr view`). - `#<N>` / `<N>` / full URL / `owner/repo#N`. ## Steps ### 1. Resolve the PR and establish the starting state ```bash gh pr view <N|--> --json number,headRefName,headRepositoryOwner,baseRefName,url,state,isDraft ``` - If the PR is already `merged` or `closed`, stop and report — there's nothing to drive. - Fetch the current review feedback using fix-pr-review step 1's three-channel query (formal reviews, issue comments, inline diff threads) to see what has already landed. - **Unaddressed feedback is already present** (a review/comment newer than any prior disposition comment, or an unresolved inline thread): treat it as the first landed review. Set `review_count = 1`, note its timestamp,...
