PR Watch

Monitor the current PR for new review comments in the background using /loop.

Parse $ARGUMENTS for options:

• --interval N → loop interval (default: 5m)

Setup

1. Confirm there's an open PR:

   gh pr view --json number --jq .number
   

2. Create a loop with CronCreate using the parsed interval and this prompt:

   Fetch all PR comments (code review + conversation). Use these commands:

   PR_NUM=$(gh pr view --json number --jq .number)
   REPO=$(gh repo view --json nameWithOwner --jq .nameWithOwner)
   # Code review comments — get all top-level (non-reply) comments with IDs
   gh api "repos/$REPO/pulls/$PR_NUM/comments" --jq '[.[] | select(.in_reply_to_id == null) | {id, body: .body[0:300], author: .user.login, created_at, path: .path}]'
   # Check which have replies already
   gh api "repos/$REPO/pulls/$PR_NUM/comments" --jq '[.[] | select(.in_reply_to_id != null) | .in_reply_to_id] | unique'
   # Conversation comments
   gh pr view --json comments --jq '.comments[] | {id, body, author: .author.login}'
   

   Ignore bot accounts (vercel, dependabot, github-actions, etc.).

   How to handle comments

   For each top-level comment that does NOT have a reply yet:

   1. Evaluate the suggestion using your own judgment. AI review bots (e.g. cubic-dev-ai, coderabbit, copilot, baz-reviewer) do NOT have full project context — their suggestions may be wrong.
   2. If valid and worth fixing: fix the code and reply confirming the fix.
   3. If valid but out of scope: reply explaining why (e.g. pre-existing pattern, low priority, will address in follow-up).
   4. If invalid or wrong: reply explaining why you disagree.
   5. Always reply to every comment so there's a clear record. Do NOT auto-resolve threads — let the reviewer handle resolution.

   A comment is "addressed" when it has a reply (from us). Check the replied-to IDs list to know which are done.

   Exit condition — only cancel this task when ALL are true:

   1. Every top-level comment has a reply (compare comment IDs vs replied-to IDs).
   2. You did NOT push any fixes in this iteration (if you pushed, wait at least TWO more iterations — checks take time to start and complete).
   3. All reviewer check runs for the latest commit have completed. Do NOT use gh pr checks (it can show stale results). Instead:

      HEAD_SHA=$(gh pr view --json headRefOid --jq .headRefOid)
      # Find incomplete checks for this exact commit
      gh api "repos/$REPO/commits/$HEAD_SHA/check-runs" --jq '[.check_runs[] | select(.status != "completed") | {name: .name, status: .status}]'
      # Also verify reviewer bots ran on THIS commit (not a previous one)
      gh api "repos/$REPO/commits/$HEAD_SHA/check-runs" --jq '[.check_runs[] | select(.name == "Baz Reviewer" or .name == "cubic · AI code reviewer") | {name: .name, status: .status, conclusion: .conclusion}]'
      

      If reviewer bots show no results for this SHA, they haven't started yet — wait. If any condition is false, wait for the next iteration.

3. Confirm to the user: "Watching PR #X every {interval}. I'll address new comments automatically and stop when everything is handled."
