Commit Message Generator

Generate a structured git commit message based on current changes and repository patterns.

When to Activate

User asks for help with commit message
User wants to generate a commit message
User needs conventional commit formatting
User asks "what should my commit say"

Quick Process

Gather Git Information:
- Run git status to see staged and unstaged changes
- Run git diff --cached to get detailed staged changes
- Run git diff to get unstaged changes (if any)
- Run git log --oneline -10 to understand repository commit patterns
Parse Input: Extract any scope or focus area from user's request
Generate Message: Create commit message following conventional format:
- Concise summary line (≤100 characters)
- Detailed explanation of WHAT and WHY (1-3 paragraphs)
- Claude Code signature

Output Format

Generate commit message in this format:

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

<body explaining WHAT changed and WHY>

Types: feat, fix, docs, style, refactor, test, chore, perf, ci, build

Examples

"Generate a commit message"
"What should my commit say for these auth changes"
"Write commit message focusing on the API updates"
"Create commit for database migration"

Delegation

Invokes the commit-message-generator agent with:

staged_changes: git diff --cached output
unstaged_changes: git diff output (for context)
commit_history: recent git log for pattern matching
scope: optional focus area from user

Safety

Never executes git commit - only generates message text
Shows message in code block for easy copying
Requires git repository with changes
