git auto commit

gac (Git Auto Commit)

Features

• AI-Powered Commit Messages: Automatically generates clear, concise, and context-aware commit messages using large language models.
• Deep Contextual Analysis: Understands your code by analyzing staged changes, repository structure, and recent commit history to provide highly relevant suggestions.
• Multi-Provider & Model Support: Flexibly works with various leading AI providers (like Anthropic, Groq, OpenAI) and models, easily configured through an interactive setup or environment variables.
• Seamless Git Workflow: Integrates smoothly into your existing Git routine as a simple drop-in replacement for git commit.
• Extensive Customization: Tailor commit messages to your needs with a rich set of flags, including one-liners (-o), AI hints (-h), commit scope (-s), and specific model selection (-m).
• Streamlined Workflow Commands: Boost your productivity with convenient options to stage all changes (-a), auto-confirm commits (-y), and push to your remote repository (-p) in a single step.
• Reroll Capability: Not satisfied with the generated commit message? Simply type r or reroll at the confirmation prompt to generate a new message.
• Token Usage Tracking: Display token consumption statistics (prompt, completion, and total tokens).

How It Works

gac analyzes your staged changes to generate high-quality commit messages with the help of large language models.

How to Use

git add .
gac

Installation and Configuration

1. Installation

Install system-wide using pipx from the GitHub repository:

# Install pipx if you don't have it
python3 -m pip install --user pipx
python3 -m pipx ensurepath

# Install gac
pipx install git+https://github.com/criteria-dev/gac.git

Verify installation:

gac --version

2. Configuration

The recommended way to configure gac is using the interactive setup:

gac init

This command will guide you through selecting an AI provider, model, and securely entering your API keys. It will create or update a user-level configuration file at $HOME/.gac.env.

Example $HOME/.gac.env output:

GAC_MODEL=anthropic:claude-3-5-haiku-latest
ANTHROPIC_API_KEY=your_anthropic_key_here

Alternatively, you can configure gac using environment variables or by manually creating/editing the configuration file.

Managing Configuration with gac config

You can manage settings in your $HOME/.gac.env file using gac config commands:

• Show config: gac config show
• Set a value: gac config set GAC_MODEL groq:meta-llama/llama-4-scout-17b-16e-instruct
• Get a value: gac config get GAC_MODEL
• Unset a value: gac config unset GAC_MODEL

3. Verify Setup

Test that gac is working properly with your configuration:

# Make a change to a file
echo "# Test change" >> README.md
git add README.md
gac -o # Generate a one-line commit message

You should see an AI-generated commit message.

4. Upgrade

To upgrade gac to the latest version, run:

pipx upgrade gac

Basic Usage

Once installed and configured, using gac is straightforward:

1. Stage your changes:

   git add .
   

2. Run gac:

   gac
   

   This will generate a commit message for review. Confirm with y to accept the message.

Common Commands

• Generate a commit message: gac
• Auto-accept the commit message: gac -y
• Stage all changes and generate a commit message: gac -a
• Generate a one-line commit message: gac -o
• Add a hint for the AI: gac -h "Fixed the authentication bug"
• Push the commit (requires accepting the commit message): gac -p
• Advanced usage: Add all, auto-confirm, push a one-liner with a hint: gac -aypo -h "update for release"

For a full list of CLI flags, advanced options, and example workflows, see USAGE.md.

Best Practices

• gac loads configuration from two locations (in order of precedence):
  1. User-level $HOME/.gac.env (applies to all projects for the user)
  2. Project-level .env (in the project root, overrides user config if present) Environment variables always take final precedence over both files.
• Keep API keys out of version control
• For troubleshooting, see docs/TROUBLESHOOTING.md
