# Commit Message

## Overview

This skill helps you generate professional git commit messages that adhere to the Conventional Commits specification. It automates the analysis of staged changes and provides a structured message that captures the intent and impact of the work.

## Workflow

### 1. Identify Staged Changes
Run `git status` to identify which files are staged for commit. If no files are staged, inform the user and ask if they would like to stage specific files.

### 2. Analyze Diffs
Run `git diff --cached` to analyze the actual changes in the staged files. For large diffs, focus on the most significant changes or summarize by file.

### 3. Draft the Message
Apply the [Conventional Commits](references/conventional-commits.md) standard to draft the message, using uppercase type wrapped in brackets.

**Format**: `[TYPE] description` or `[TYPE](scope) description`

- **Type**: Choose the most appropriate type and write it UPPERCASE in brackets: `[FEAT]`, `[FIX]`, `[DOCS]`, `[STYLE]`, `[REFACTOR]`, `[PERF]`, `[TEST]`, `[BUILD]`, `[CI]`, `[CHORE]`, `[REVERT]`.
- **Scope**: (Optional) Add a scope in parentheses after the type bracket: `[FEAT](auth)`.
- **Description**: Write a concise, imperative-mood summary of the change.
- **Body**: (Optional) Provide a more detailed explanation if the changes are complex or require context.
- **Breaking Changes**: Note with `[FEAT!]` or `[FIX!]` (exclamation inside the bracket) and explain in the body.

### 4. Present and Refine
Present the drafted message to the user. Ask if they would like to use it as-is, make adjustments, or if they want a different version.

## Examples

### Request: "Commit these changes"
**Response**: "I see you have staged changes in `src/auth.ts` and `src/user.ts`. I've analyzed the diff and suggest the following commit message:
`[FEAT](auth) add JWT-based session management`
Would you like me to commit with this message?"

### Request: "Give me a commit message for my work"
**Response**: "Based on your changes in `docs/api.md`, I suggest:
`[DOCS] update API endpoints for user registration`
Does this look good to you?"

## Guidelines
- **Imperative Mood**: Use "add", "fix", "update" instead of "added", "fixed", "updates".
- **Conciseness**: Keep the first line (header) under 50-72 characters if possible.
- **Context**: Use the commit body for "why" rather than "what" (the diff shows "what").
