CLAUDE.md Content Requirements

CLAUDE.md は簡潔に保ち、他ドキュメントで参照可能な内容は削除する。

含めるべき内容

1. Blog Philosophy: このリポジトリ固有の設計思想
2. Project Overview: 概要と他ドキュメントへの参照リンク
3. Environment Configuration: 3 環境構成図
4. Release Flow: CI/CD フロー図
5. Authentication: 認証方式
6. Package Names: パッケージ名一覧
7. Key Technical Decisions: 技術選定
8. Deployment: デプロイ情報（概要のみ）
9. Tool Management: ツール管理（簡潔に）

他ドキュメントへ委譲する内容

簡潔化ルール

• 冗長な記述は削除し、参照リンクを記載
• コマンド一覧は just --list で確認可能なため詳細不要
• テーブルは必要最小限の列のみ
• 重複を避け、Claude Code に必要な情報のみを記載

README.md Content Requirements

1. Project Title and Description
2. Prerequisites: Homebrew, mise, pnpm
3. Quick Start: Bootstrap and dev commands
4. Documentation Links: Links to detailed docs
5. License

Workflow

1. Read existing documentation files
2. Read justfile to extract command documentation
3. Read .github/workflows/ to extract required GitHub Secrets
4. Generate English CLAUDE.md with all required sections
5. Generate English README.md
6. Create docs/ directory if not exists
7. Generate Japanese translations (*.ja.md)
8. Add cross-links to all files
9. Remove old DEVELOPMENT.md from root (if moved to docs/)
10. Run prek run -a to verify all linting passes

Translation Guidelines

• Keep code blocks, commands, file paths, and URLs as-is
• Translate prose content naturally
• Maintain consistent terminology
• Keep table structure identical
• Preserve markdown formatting

Verification

After completion, run:

prek run -a

All checks must pass before considering the task complete.
