commit

ステージング済みまたは未ステージングの変更を、リポジトリの既存のコミットスタイルに合ったAI生成のコミットメッセージと共にコミットします。ユーザーが「コミット」と依頼した場合に使用します。

Commit Changes

Help the user commit code changes with a well-crafted commit message derived from the diff, following the conventions already established in the repository.

Guidelines

Never amend existing commits without asking.
Never force-push or push without explicit user approval.
Never skip pre-commit hooks (do not use --no-verify).
Never skip signing commits (do not use --no-gpg-sign).
Never revert, reset, or discard user changes unless the user explicitly asked for that.
Check for obvious secrets or generated artifacts that should not be committed. If something looks risky - ask the user.
When in doubt about staging, convention, or message content — ask the user.

Workflow

1. Discover the repository's commit convention

Run the following to sample recent commits and the user's own commits:

# Recent repo commits (for overall style)
git log --oneline -20

# User's recent commits (for personal style)
git log --oneline --author="$(git config user.name)" -10

Analyse the output to determine the commit message convention used in the repository (e.g. Conventional Commits, Gitmoji, ticket-prefixed, free-form). All generated messages must follow the detected convention.

2. Check repository status

git status --short

If there are no changes (working tree clean, nothing staged), inform the user and stop.
If there are staged changes, proceed with those and do not stage any unstaged changes.
If there are only unstaged changes, stage everything (git add -A), and proceed with those.

3. Generate the commit message

Obtain the full diff of what will be committed:

git diff --cached --stat
git diff --cached

Using the diff and the commit convention detected in step 1, draft a commit message with:

A subject line (≤ 72 characters) that summarises the change, following the repository's convention.
An optional body that explains why the change was made, only when the diff is non-trivial.
Reference issue/ticket numbers when they appear in branch names or related context.
Focus on the intent of the change, not a file-by-file inventory.

4. Commit

Construct the git commit command with the generated message.

Execute the commit:

git commit -m "<subject>" -m "<body>"

5. Confirm

After the commit:

Run git status --short to confirm the commit completed.
Run git log --oneline -1 to show the new commit.
If pre-commit hooks changed files or blocked the commit, summarize exactly what happened.
If hooks rewrote files after the commit attempt, do not amend automatically. Tell the user what changed and ask whether they want you to stage and commit those follow-up edits.
