name: commitmsg description: Generate a concise commit message by analyzing git diff changes

Commit Message Generator

This skill analyzes the changes in your git repository and generates a concise, single-line commit message that follows conventional commit standards.

How to use this skill

When you want to create a commit message for your changes:

1. Run the commitmsg.sh script in this directory
2. The script will analyze the git diff of staged changes
3. It will output a single line commit message you can use

Example usage

Copy# Stage your changes first
git add .

# Generate commit message
./commitmsg.sh

# Use the output as your commit message
git commit -m "feat: add user authentication system"

What the script does

The commitmsg.sh script:

• Checks if you're in a git repository
• Gets the diff of staged changes (or working directory if nothing staged)
• Analyzes the changed files and their content
• Generates a concise commit message following conventional commit format
• Outputs a single line suitable for git commit -m

Conventional commit format

The generated messages follow the pattern:

• feat: for new features
• fix: for bug fixes
• docs: for documentation
• style: for formatting changes
• refactor: for code restructuring
• test: for test additions
• chore: for maintenance tasks

Each message includes a brief description of what changed.
