サブエージェントを活用した並列実行・調査委譲・コンテキスト管理の戦略。複雑な問題への対処、調査・探索タスク、複数の選択肢の比較検討、大規模なリファクタリングなどでこのスキルを参照する。「調べて」「比較して」「並列で」「複数のアプローチを試して」といったリクエストや、メインのコンテキストが肥大化しそうな場面で使う。

This skill should be used when the user asks to "このIssueを実装して", "implement this issue", "fix this bug", "このタスクをやって", "Issue

This skill should be used when the user asks to "これらのIssueを全部実装して", "implement these issues autonomously", "Issue一覧を自動で片付けて", "これらのタスクを順番に実装してPRにして", or provides a list of GitHub Issue numbers/URLs for autonomous batch implementation. Fetches all specified Issues, resolves dependency order, then iterates through each — creating a worktree, implementing, and opening a PR — without user intervention.

This skill should be used when the user asks to "既存プロジェクトのタスクを整理して", "技術的負債をIssue化して", "このコードベースを改善するタスクを洗い出して", "GitHub Projectに健全化タスクを登録して", "break down what needs to be fixed in this project", "surface tech debt as issues", or "create a project board for cleanup work". Diagnoses pain points and codebase health of an existing project, then registers improvement tasks as GitHub Issues and a Project Board.

This skill should be used when the user asks to "最小再現環境を作って", "再現環境を構築して", "問題を切り分けたい", "パッケージの不具合か確認したい", "create a minimal reproduction", "isolate the issue", "build a repro environment", "reproduce this bug", "narrow down the cause", "is this a package bug or my code", "このPRの問題を再現して", "this commit broke something", or wants to determine whether a bug is caused by a package, the environment, or application code. Accepts PR URLs, commit hashes, or branch names as input.

This skill should be used when the user asks to "sandboxの互換性をチェックして", "sandbox設定を確認して", "このプロジェクトでsandboxが使えるか調べて", "sandboxでコマンドが失敗する", "check sandbox compatibility", "verify sandbox settings", "sandbox is blocking my commands", or wants to ensure their development workflow works within Claude Code's sandbox restrictions — either proactively before starting work or reactively after encountering sandbox-related failures.

非自明なタスク（3ステップ以上、アーキテクチャ判断、複数ファイルにまたがる変更）に取り組む際の計画・実行・検証サイクル。タスクの開始時、実装がうまくいかず再計画が必要な時、バグ修正やリファクタリングの着手時にこのスキルを参照する。「計画を立てて」「TODO を整理して」「この機能を実装して」「バグを直して」といったリクエストや、明らかに複数ステップを要するタスクではこのスキルを使う。ただし、大規模な新機能開発（コードベース探索・アーキテクチャ設計・並列レビューが必要な重量級タスク）には feature-dev プラグイン（/feature-dev）の方が適切。

Configure a Node.js project with pnpm, TypeScript, latest versions, and parallel script patterns following modern best practices

This skill should be used when the user asks to "プロジェクトを解析して", "コードベースを調べてドキュメント化して", "移行作業の準備をして", "新機能実装の前にプロジェクトを整理して", "analyze this codebase", "document the project structure", "既存プロジェクトのCLAUDE.mdを作って", or wants to prepare CLAUDE.md and architecture docs before a migration, feature development, or onboarding.

This skill should be used when the user asks to "このエラーを直して", "help me debug this", "fix this stack trace", "なぜこのエラーが出るの", "CI が落ちた", or pastes an error message or stack trace and wants help diagnosing it. Classifies the error type, identifies related files, and proposes up to three root-cause hypotheses with concrete fix plans.

This skill should be used when the user asks to "このファイルを変えたら何が壊れる？", "what depends on this function", "影響範囲を調べて", "show me what imports this module", or wants to understand the blast radius before modifying a shared utility, exported type, or public API. Traces import/require references up to two levels deep and lists affected test files.

This skill should be used when the user asks to "ドキュメントを更新して", "sync the docs", "update CLAUDE.md after this change", "実装に合わせてドキュメントを直して", or notices that docs have drifted from the codebase. Diffs git history to identify what changed, proposes targeted updates to CLAUDE.md, docs/architecture.md, docs/requirements.md, and README.md, then applies only approved changes.

This skill should be used when the user asks to "PR を出す前に確認して", "check if this branch is ready to merge", "run pre-PR checks", "PRを作る前にチェックして", or wants to verify a branch before opening a pull request. Executes verification commands, validates Conventional Commits format, and confirms documentation is updated, then reports whether gh pr create is safe to run.

Guide the user through starting a new web application project — elicit requirements (MoSCoW scoping), create architecture and requirements documents, break work into tasks, and register them as a GitHub Project kanban board. Use when the user says "新しいWebアプリを作りたい", "Webアプリの立ち上げを手伝って", "start a new web app project", "プロジェクトの要件を整理したい", or "GitHub Projectにタスクを登録したい".

Explain selected code or a specified file/function in plain language, including what it does, why it exists, and potential pitfalls

Route a PR review request to the correct tool — code-review plugin (quick parallel scan across all dimensions) or pr-review-toolkit (deep-dive on a specific quality dimension such as type design, error handling, test quality, comments, or simplification). Use when the user asks for a code review, PR review, or mentions a specific quality concern before creating a PR.

ユーザーからの修正・指摘を受けた際の学習記録と自己改善ループ。ユーザーから「違う」「そうじゃない」「前にも言ったけど」といった修正を受けた時、同じミスを繰り返していると気づいた時、セッション開始時の教訓確認で使う。修正やフィードバックを受けたら必ずこのスキルを参照する。
