description	Fan-out code review of multiple/all open PRs - one parallel worktree-isolated agent per PR, each following the review-pr skill protocol, then cross-PR verification, cleanup and summary. Use when asked to review all open PRs or several PRs at once; a single PR needs only review-pr.

Multi-agent review of open PRs

Orchestration only — the per-PR review protocol lives in .claude/skills/review-pr/SKILL.md and is NOT duplicated here.

1. Discover the PRs and the stack topology

gh pr list --state open --json number,title,headRefName,baseRefName,url --limit 50

Note which PRs are stacked (baseRefName ≠ main) — pass each PR's base branch into its agent prompt so the "own diff only" rule is explicit.

2. Launch one agent per PR

Agent tool, all launches in a single message (parallel), each with isolation: "worktree" so agents can gh pr checkout and run the test suite without touching the main checkout or each other.

Each agent's prompt:

• "You are an expert Kubernetes/Helm code reviewer. Review PR # (, base <baseRefName>) and post the review to GitHub."
• "Follow the protocol in .claude/skills/review-pr/SKILL.md — read it first; the (parallel) notes apply to you."
• PR-specific hypotheses worth chasing (see the review-focus section of review-pr) — tailor them per PR; this is what separates real findings from style nits.
• "Return a severity-ranked findings report, verification results, and the posted review URL."

3. After all agents finish

1. Verify every review landed on the right PR (the shared-scratchpad collision described in review-pr makes this non-optional):

   for pr in <numbers>; do echo "=== PR #$pr ==="; \
     gh api repos/shopsys/helm/pulls/$pr/reviews \
       --jq '.[] | select(.body | contains("Claude Agent (CR)")) | "\(.id) [\(.state)]"'; done
   

2. Clean up the agent worktrees (a PR-branch checkout marks them "changed", so they are not auto-removed):

   git worktree list | grep agent- | awk '{print $1}' \
     | while read wt; do git worktree remove --force "$wt"; done
   git branch | grep worktree-agent | xargs -r git branch -D
   

3. Summarize for the user: cross-PR severity ranking (lead with the worst finding overall, not per-PR), per-PR test results, and links to all posted reviews.
