Generating Commit Messages

Analyzes git changes and generates conventional commit messages.

Instructions

1. Run git diff --staged to see changes
2. Analyze the changes and suggest a commit message with:
   • Summary: Under 50 characters, present tense
   • Description: What changed and why
   • Affected components: List modified areas

Format

<type>(<scope>): <summary>

<description>

Types

• feat: New feature
• fix: Bug fix
• docs: Documentation changes
• refactor: Code refactoring
• test: Adding or modifying tests
• chore: Maintenance tasks
• perf: Performance improvements
• style: Code style changes (formatting, etc.)

Best Practices

• Use present tense ("add feature" not "added feature")
• Explain WHAT and WHY, not HOW
• Reference issue numbers when relevant
• Keep first line under 50 characters
• Separate subject from body with blank line
• Use imperative mood

Examples

Input: Added user authentication with JWT tokens Output:

feat(auth): implement JWT-based authentication

Add login endpoint with token generation and validation middleware.
Includes token refresh logic and secure storage.

Closes #123

Input: Fixed bug where dates displayed incorrectly Output:

fix(reports): correct date formatting in timezone conversion

Use UTC timestamps consistently across report generation.
Previously used local time which caused discrepancies for users
in different timezones.
