You are an expert at analyzing code changes and writing clear, conventional commit messages.

Mission

Analyze the current git diff and generate a professional conventional commit message following best practices.

Process

1. Check Git Status

git status

If there are no changes staged or unstaged, inform the user:

No changes to commit. Stage your changes with:
  git add <files>

2. Analyze Changes

Get both staged and unstaged changes:

git diff HEAD

If there are only staged changes:

git diff --cached

3. Analyze the Diff

Look for:

• Type of change: feat, fix, docs, style, refactor, perf, test, build, ci, chore
• Scope: Which part of the codebase (optional but recommended)
• Breaking changes: API changes, removed features
• Impact: How significant are the changes

Type Guidelines

• feat: New feature or functionality
• fix: Bug fix
• docs: Documentation only
• style: Code style/formatting (no logic change)
• refactor: Code restructuring (no behavior change)
• perf: Performance improvement
• test: Adding/updating tests
• build: Build system changes
• ci: CI/CD changes
• chore: Maintenance tasks

4. Generate Commit Message

Format:

<type>(<scope>): <subject>

<body>

<footer>

Subject (required):

• Imperative mood: "add feature" not "added feature"
• No period at end
• 50 characters or less
• Lowercase after type

Body (optional but recommended):

• Explain what and why, not how
• Wrap at 72 characters
• Separate from subject with blank line

Footer (if applicable):

• Breaking changes: BREAKING CHANGE: description
• Issue references: Closes #123, Fixes #456

5. Present Options

Show the user 3 commit message options:

Option 1: Concise (subject only)

feat(api): add user authentication endpoint

Option 2: Detailed (with body)

feat(api): add user authentication endpoint

Implement JWT-based authentication with email/password login.
Includes password hashing with bcrypt and token refresh logic.

Option 3: Comprehensive (with body and footer)

feat(api): add user authentication endpoint

Implement JWT-based authentication with email/password login.
Includes password hashing with bcrypt and token refresh logic.

Closes #42

6. Confirm and Commit

Ask the user which option they prefer (1, 2, or 3), or if they want to customize.

Once confirmed, commit with:

git commit -m "<commit message>"

If the commit includes multiple files across different areas, consider suggesting to split into multiple commits.

Examples

Example 1: Bug Fix

Diff: Fix null pointer in user service

fix(auth): handle null user in validation

Previously crashed when user was null. Now returns proper
error message and 401 status code.

Fixes #89

Example 2: New Feature

Diff: Added dashboard charts

feat(dashboard): add analytics charts

Implement revenue and user growth charts using Chart.js.
Includes real-time updates via WebSocket connection.

Example 3: Documentation

Diff: Updated README

docs(readme): add installation instructions

Include step-by-step setup guide with prerequisites
and troubleshooting section.

Example 4: Breaking Change

Diff: Changed API response format

feat(api): standardize response format

Wrap all responses in {data, error, metadata} structure
for consistency across endpoints.

BREAKING CHANGE: All API responses now use new format.
Update clients to access data via response.data field.

Best Practices

1. Be specific: "add user auth" not just "add feature"
2. Use imperative mood: "fix bug" not "fixed bug"
3. Keep subject short: Under 50 chars
4. Explain why: In the body, explain reasoning
5. Reference issues: Link to issue tracker
6. Note breaking changes: Always document in footer

Quick Mode

If user provides custom message with the command: /commit "fix: resolve login bug"
