commit-by-logical-units

A workflow for splitting uncommitted Git changes into separate commits that each represent one logical change. Git commits are saved checkpoints in a project's history.

In plain words
What is it for?
Use it to inspect changes and recent commit style, group related files, create clear English commit messages, and check the repository after committing.
Why use it?
It makes project history easier to understand, review, and selectively undo. It also helps keep generated files, dependencies, and secrets such as .env files out of commits.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

commit-by-logical-units scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

現在の変更内容を確認し、論理的に意味がある単位で複数のコミットに分けて実行してください。

以下の手順で実行してください:

  1. 変更内容の確認

    • git statusで変更されたファイルを確認
    • git diff --statで変更の統計情報を確認
    • git log --oneline -10で最近のコミット履歴を確認し、コミットメッセージのスタイルを把握
  2. 変更内容の分析

    • いくつかの代表的なファイルの差分を確認(git diff [ファイルパス] | head -50
    • 変更の性質を理解し、論理的なグループに分類
    • 例:
      • ルートディレクトリのファイル
      • 機能別のドキュメント(features, getting-started, recipes, tools, publishingなど)
      • 設定ファイル
      • テストファイル
      • ソースコード(機能ごと、モジュールごと)
  3. 論理的な単位でコミット

    • 各グループごとにgit add [ファイル/ディレクトリ]git commitを実行
    • コミットメッセージは英語で簡潔に記述
    • コミットメッセージの形式:
      git commit -m "$(cat <<'EOF'
      変更の概要を1行で記述
      
      詳細な説明(必要に応じて)
      
      Co-Authored-By: Claude Sonnet 4.5 <[email protected]>
      EOF
      )"
      
  4. コミット後の確認

    • git statusで残りの変更を確認
    • git log --oneline -10でコミット履歴を確認

重要な原則

  • 論理的な単位: 関連する変更を1つのコミットにまとめる
  • 簡潔なメッセージ: 何を変更したかを明確に記述
  • 英語で記述: コミットメッセージは英語で書く
  • 複数コミット推奨: 大きな変更は複数のコミットに分ける
  • 意味のあるグループ化: ディレクトリ構造や機能に基づいてグループ化

除外すべきファイル

以下のファイルは通常コミットしない:

  • .envファイル(環境変数、機密情報)
  • node_modules/(依存関係)
  • ビルド成果物

これらのファイルが変更されている場合は、ユーザーに確認するか、無視してください。

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

commit-by-logical-units is a skill published in the GitHub repository backpaper0/claude-code-in-devcontainer-example (5 stars, last pushed 6mo ago), licensed MIT. It adds 33 tokens to every session and 700 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
