Conventional Commits for emoji_gen

This Skill helps create commit messages that follow the Conventional Commits specification and include the required Claude Code footer.

Commit Message Format

<type>[optional scope][optional !]: <description>

[optional body]

[required footer]

Types

• feat: New feature for the user or library
• fix: Bug fix for the user
• docs: Documentation changes only
• build: Changes to build system or dependencies (Cargo.toml, Dockerfile, CI)
• test: Adding or updating tests
• refactor: Code changes that neither fix bugs nor add features
• perf: Performance improvements
• chore: Maintenance tasks, tooling changes

Scope Examples

• feat(cli): - CLI-related feature
• fix(parser): - Parser bug fix
• build(docker): - Docker build changes
• docs(readme): - README updates

Breaking Changes

Indicate with ! after type/scope:

Or use BREAKING CHANGE: footer:

Instructions for Creating Commits

1. Run git diff to understand changes:

   git diff --staged
   # or
   git diff
   

2. Analyze the changes to determine:

   • Appropriate type (feat, fix, docs, build, etc.)
   • Optional scope (cli, docker, ci, etc.)
   • Whether it's a breaking change
   • Clear, concise description (imperative mood)

3. Draft commit message following the template in commit-template.txt

4. Use heredoc format for multi-line commits:

   git commit -m "$(cat <<'EOF'
   feat: add emoji category support
   
   Adds categorization system for emojis (animals, food, symbols).
   Users can now filter by category using --category flag.

   EOF
   )"
   

Best Practices

• Use imperative mood: "add" not "added", "fix" not "fixed"
• Keep summary under 50 characters when possible
• Explain what and why, not how
• Reference issue numbers in body if applicable
• Always include the Claude Code footer
• Use body for context if the change needs explanation

Error Prevention

DO NOT:

• Forget the Claude Code footer
• Use past tense ("added", "fixed")
• Write vague descriptions ("update stuff", "fix bug")
• Skip the body when breaking changes need explanation
• Commit without running git diff first

DO:

• Always check staged changes first
• Use clear, specific descriptions
• Include body for context when needed
• Use appropriate type and scope
• Include the required footer
