description	Iterate on CodeRabbit spec PR reviews until convergence, then label ready-to-build

Automate the spec review cycle for open spec PRs. Fetch CodeRabbit findings, fix issues, iterate until convergence, and label PRs ready-to-build.

Workflow

1. Discover Spec PRs

If PR numbers were provided as arguments, use those. Otherwise, find all open PRs matching spec/* branches:

gh pr list --state open --head "spec/" --json number,headRefName,title,labels,updatedAt

If no spec PRs are found, report that and stop.

2. For Each PR — Assess Review Status

For each spec PR, gather:

• CodeRabbit review status: Check PR reviews and inline comments
• Actionable comment count: Comments that are not resolved or outdated
• Last review timestamp: When CodeRabbit last reviewed
• Current labels: Whether ready-to-build is already applied

# Get PR reviews
gh pr view <number> --json reviews,comments,labels,headRefName

# Get inline review comments with file paths
gh api repos/{owner}/{repo}/pulls/<number>/comments --jq '.[] | {path: .path, body: .body, line: .line, created_at: .created_at, in_reply_to_id: .in_reply_to_id}'

3. Present Summary

Display a summary table showing the status of each spec PR:

PR	Branch	Title	Actionable	Last Review	Status
#42	spec/add-alerts	Add alert providers	3	2h ago	Needs fixes
#43	spec/update-drift	Update drift detection	0	1h ago	Converged

4. Fix Findings

For PRs with actionable findings, offer to dispatch worktree-isolated agents (one per PR) to:

1. Check out the spec branch in a worktree
2. Read each CodeRabbit comment with file path and suggested fix
3. Apply fixes to the spec files
4. Commit and push the fixes

Use the Agent tool with isolation: "worktree" to prevent cross-PR conflicts.

After fixes are pushed, CodeRabbit will automatically re-review. Wait ~5 minutes for the review. If no review appears, suggest triggering manually:

gh pr comment <number> --body "@coderabbitai review"

5. Iterate

Re-run the assessment (step 2) after each fix round. Continue until:

• Converged: 0 actionable comments, or only stale/repeated findings
• Stalled: Same findings persist after 2 fix rounds (escalate to user)

6. Label ready-to-build

When a PR converges, apply the label:

gh pr edit <number> --add-label "ready-to-build"

Report final status for all PRs.

Convergence Criteria

A spec PR is converged when ANY of:

• CodeRabbit leaves 0 new comments on the latest push
• All remaining comments are resolved or are repeats of previously addressed findings
• The review summary shows no actionable items

Rate Limiting

CodeRabbit may rate-limit reviews on rapid successive pushes. If a review doesn't appear within ~5 minutes after a push:

1. Check if the PR has a pending review status
2. Trigger manually with @coderabbitai review as a PR comment
3. Wait another 5 minutes before escalating
