Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# CLAUDE.md Optimizer Claude 4公式ベストプラクティスに基づき、CLAUDE.mdファイルを最適化するスキル。 ## Execution Flow ### 1. Read target CLAUDE.md 既存の内容を確認。なければ新規作成を提案。 ### 2. Analyze against Claude 4 principles 詳細は `claude4-principles.md` を参照。主要評価軸: - **明示性**: 指示が具体的か。修飾語（"as many as possible"）を使っているか - **コンテキスト**: なぜそのルールが必要か説明しているか - **構造**: XMLタグで整理されているか（必要な場合） - **過剰防止**: 過度なエンジニアリングを抑制する指示があるか ### 3. Apply optimizations チェックリストは `checklist.md` を参照。主要な最適化: - 曖昧な指示 → 明示的・具体的な指示に変換 - ルールのみ → 理由（なぜ）を追加 - 過度な冗長性 → 簡潔かつ必要十分に - 不足している重要指示を追加（過剰エンジニアリング防止など） ### 4. Report improvements 変更点とClaude 4原則への対応を説明。 ## Output Format 課題 → 改善案 → 変更点（テーブル形式）の順で報告。 ## Reference Files - `claude4-principles.md`: Claude 4モデル固有のベストプラクティス詳細 - `checklist.md`: CLAUDE.md最適化チェックリスト

How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill claudemd-optimizer --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
