PR 差分 or ローカルブランチ差分に対してレビュー本文 (body / event / comments[]) を生成する skill。`/pr-review-style-reference` slash command とプロジェクト指示ファイル (REVIEW.md / AGENTS.md / .claude/CLAUDE.md / CLAUDE.md) を読み込んでレビュー方針を決め、差分を読んで `post-pr-review` のスキーマに揃った JSON を **`HANDOFF_PATH` (省略時は既定 temp パス) にファイル書き出しし、最終メッセージでは「そのファイルを Read して続行せよ」という継続指示を返す** (停止防止のため自己完結 JSON は最終メッセージに出さない)。レビュー指摘は自前レビューを必ず行い、加えてホストの外部レビュースキル (優先順: `code-review` (Claude Code 組み込み) → ホスト標準レビュースキル例 Codex `/review` → 無し) を 1 つ併用して指摘をマージする (通常は常に併用。外部スキルが 1 つも使えないときだけ自前単独)。`run-pr-review` / `run-local-review` orchestrator や Codex 等他 caller から現在コンテキストで直接 Skill ツール経由で呼ばれる。GitHub 投稿 / 過去スレッド resolve は行わない (read-only)。

From the source SKILL.md

差分 + 方針 → レビュー本文 (body / event / comments[]) を生成する skill。完成 JSON は HANDOFF_PATH (省略時は既定 temp パス) にファイルとして書き出し、最終メッセージでは「そのファイルを Read して続行せよ」という継続指示を返す (詳細は Step 6)。最終メッセージに自己完結 JSON を出さない — 自己完結 JSON は「タスク完了」シグナルに見え、caller (orchestrator) が投稿 step を実行する前にターンを終了してしまう停止バグを誘発するため、ファイル経由ハンドオフ + 継続指示に一本化している。
