Smart Commit

Create meaningful conventional commits by analyzing your actual changes.

Workflow

Step 1: Assess the working tree

Run these commands to understand the current state:

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

Step 2: Handle unstaged changes

If nothing is staged (git diff --cached is empty):

1. Show the user what files have changed
2. Suggest what to stage based on logical grouping (e.g., "these 3 files are all related to the auth refactor")
3. Ask if they want to stage all, or select specific files
4. Stage the approved files with git add <files>

If changes are already staged, proceed to analysis.

Step 3: Analyze the diff

Read the full staged diff:

git diff --cached

Determine the commit type from the changes:

Determine the scope from the primary directory or module affected:

• src/api/ -> api
• src/components/auth/ -> auth
• tests/ -> tests
• Root config files -> omit scope
• Multiple unrelated areas -> omit scope

Step 4: Check for user overrides

If the user provided arguments via $ARGUMENTS:

• Single word (e.g., fix) -> use as commit type
• Two words (e.g., refactor api) -> use as type and scope
• Otherwise -> use auto-detected values

Step 5: Compose the commit message

Format: type(scope): imperative short description

Rules:

• Subject line max 72 characters
• Use imperative mood ("add", "fix", "refactor", not "added", "fixes")
• Don't end with a period
• Body explains WHY this change was made, not what changed (the diff shows what)
• If changes are trivial (typo fix, formatting), skip the body

Example:

feat(auth): add JWT refresh token rotation

Tokens were expiring mid-session for users with slow connections.
Rotating refresh tokens extends the session without compromising
security, since each refresh token can only be used once.

Step 6: Confirm and commit

Show the user the proposed commit message and ask for confirmation.

If confirmed, run:

git commit -m "<message>"

Then verify with:

git log --oneline -1

Show the committed hash and message.

Tips

• Run after completing a logical unit of work, not after every file change
• If the diff is too large for one commit, suggest splitting into multiple commits
• For breaking changes, add ! after the scope: feat(api)!: change response format
• The body should answer "if someone reads this commit in 6 months, will they understand WHY?"
