Commit Message Skill

A Claude Code slash command (/commit-msg) that automatically generates Conventional Commits-compliant commit messages by analyzing your staged git diff.

Features

• Reads git diff --staged to understand what changed
• Detects commit type (feat, fix, refactor, etc.) from the nature of changes
• Infers scope from affected file paths
• Supports --scope, --type, and --breaking overrides
• Outputs properly formatted messages like feat(auth): add OAuth2 login with GitHub provider

Usage

Stage your changes, then run:

/commit-msg

Options

Flag	Description
--scope	Override the auto-detected scope
--type	Force a specific commit type
--breaking	Mark the commit as a breaking change

Example Output

feat(auth): add OAuth2 login with GitHub provider
fix(api): handle null response from external service
refactor(db): migrate queries to prepared statements
