Commit Message Generator

Generate a commit message for the following changes.

Format

Use conventional commits format:

<type>(<scope>): <description>

[optional body]

[optional footer]

Types

• feat: New feature
• fix: Bug fix
• docs: Documentation changes
• style: Formatting, missing semicolons, etc.
• refactor: Code restructuring without behavior change
• perf: Performance improvements
• test: Adding or updating tests
• chore: Maintenance tasks, dependencies

Guidelines

1. Subject line: 50 characters max, imperative mood
2. Body: Explain what and why, not how
3. Footer: Reference issues, breaking changes
