Git Commit Helper

Git Commit Helper

Quick start

Analyse staged changes and generate a commit message:

git diff --staged

Commit message format

Follow conventional commits format:

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

[optional body]

[optional footer]

Types

• feat: New feature
• fix: Bug fix
• docs: Documentation changes
• style: Code style changes (formatting, missing semicolons)
• refactor: Code refactoring
• test: Adding or updating tests
• chore: Maintenance tasks

Example

feat(auth): add JWT authentication

Implement JWT-based authentication system with:
- Login endpoint with token generation
- Token validation middleware
- Refresh token support

For more examples (bugfix, refactor, multi-file, breaking changes, scopes), see references/examples.md.

Commit message guidelines

DO:

• Use imperative mood ("add feature" not "added feature")
• Keep first line under 50 characters
• Capitalise first letter
• No period at end of summary
• Explain WHY not just WHAT in body

DON'T:

• Use vague messages like "update" or "fix stuff"
• Include technical implementation details in summary
• Write paragraphs in summary line
• Use past tense

Template workflow

1. Review changes: git diff --staged
2. Identify type: Is it feat, fix, refactor, etc.?
3. Determine scope: What part of the codebase?
4. Write summary: Brief, imperative description
5. Add body: Explain why and what impact
6. Note breaking changes: If applicable

For git commands (analysing diffs, interactive staging, amending commits), see references/git-commands.md.

Best practices

1. Atomic commits - One logical change per commit
2. Test before commit - Ensure code works
3. Reference issues - Include issue numbers if applicable
4. Keep it focused - Don't mix unrelated changes
5. Write for humans - Future you will read this

Commit message checklist

• Type is appropriate (feat/fix/docs/etc.)
• Scope is specific and clear
• Summary is under 50 characters
• Summary uses imperative mood
• Body explains WHY not just WHAT
• Breaking changes are clearly marked
• Related issue numbers are included
