# Claude Code Git Integration

This document explains how to use the custom git commands created for Claude Code to summarize file changes and commit them with proper attribution.

## Installation

The custom git command has been installed in your system with the following components:

1. A `git-claude` script in `~/bin/` directory
2. A git alias `claude` that points to the script
3. A git hook that automatically summarizes changes in commit messages

## Usage

### 1. Summarize Changes

To get a summary of current changes in your repository:

```bash
git claude summarize
```

This command will show:
- Staged changes (files ready to be committed)
- Unstaged changes (modified files not yet staged)
- Untracked files (new files not yet added to git)

### 2. Commit with Claude Signature

To commit changes with the proper Claude Code signature:

```bash
git claude commit "Your commit message here"
```

This command will:
- Stage all changes if none are currently staged
- Create a commit with your message
- Automatically add the Claude Code signature:
  ```
  🤖 Generated with [Claude Code](https://claude.ai/code)
  
  Co-Authored-By: Claude <noreply@anthropic.com>
  ```

### 3. Using Standard Git Commands

You can also use standard git commands which will now include Claude Code summaries:

```bash
# Standard git add and commit
git add .
git commit -m "Your message"

# The prepare-commit-msg hook will automatically add a summary
```

## How It Works

1. **Git Hook**: The `prepare-commit-msg` hook in `.git/hooks/` automatically adds a summary of changes to your commit messages.

2. **Custom Command**: The `git-claude` script provides a convenient interface for common Claude Code workflows.

3. **Git Alias**: The `git claude` alias allows you to use `git claude` instead of `git-claude`.

## Examples

```bash
# Get a summary of current changes
git claude summarize

# Commit changes with a custom message
git claude commit "Add new user authentication feature"

# Commit changes with default message
git claude commit
```

## Troubleshooting

If you encounter any issues:

1. Make sure the `~/bin/` directory is in your PATH
2. Verify the script is executable: `chmod +x ~/bin/git-claude`
3. Check that the git alias is properly configured: `git config --get-regexp alias.claude`

## Customization

You can customize the behavior by modifying the scripts in:
- `~/bin/git-claude` - Main script
- `.git/hooks/prepare-commit-msg` - Commit message hook
