Request GitHub Review Skill

Request an automated reviewer on a GitHub pull request using the Copilot → Codex + Claude fallback chain.

Input

A PR number. Detect it from context (e.g. recent gh pr create output, current branch PR) or ask the human: “Which PR number should I request a review for?”

Steps

1. Try Copilot first.

   gh pr edit {number} --add-reviewer "Copilot"
   

2. If that command exits non-zero, inspect the error output:

   • If it contains any of: "Could not resolve to a User", "not found", "is not a collaborator", "does not have access" — these signal that Copilot is permanently not configured on this repo. Fall through to Step 3.
   • If it fails for any other reason (network error, auth failure, rate limit, unexpected output) — do not fall through. Surface the error to the human and stop.

3. Fall back to @codex and @claude review comments.

   Post both trigger comments:

   gh pr comment {number} --body "@codex review"
   gh pr comment {number} --body "@claude review"
   

   Both are best-effort. Each bot must be installed and enabled on the repo for the comment to queue a review — gh exits 0 regardless of whether a review was actually queued. Inform the human of this uncertainty for each.

4. If Step 3 fails (i.e. either gh pr comment exits non-zero), warn the human about the failure and stop.

Output

Report the outcome clearly:

• “Added Copilot as reviewer on PR #{number}.” — if Step 1 succeeded.
• “Copilot is not available as a reviewer on this repo (permanent configuration state, not a transient failure). Posted @codex review and @claude review on PR #{number} — reviews will be queued if the respective bots are installed.” — if Step 3 was used.
• Surface errors verbatim if either step failed unexpectedly.
