git-commit-msg-ai 1.4.0

AI-powered git commit message generator following Conventional Commits

git-commit-msg-ai

AI-powered git commit message generator that follows the Conventional Commits specification.

Prerequisites

• Python 3.10+

• An Anthropic API key set as an environment variable:

  export ANTHROPIC_API_KEY=sk-ant-...   # macOS/Linux
  

  [System.Environment]::SetEnvironmentVariable('ANTHROPIC_API_KEY', 'sk-ant-...', 'User')   # Windows
  

Installation

pip install git-commit-msg-ai

Usage

Stage your changes, then run the tool from inside any git repository:

git add <files>
git-commit-msg-ai

The tool will:

1. Read your staged diff
2. Generate a commit message using Claude AI
3. Print the message and prompt you to choose:

[a]ccept / [e]dit / [r]eject:

• a — commits immediately with the generated message
• e — opens the message in your $EDITOR (defaults to notepad on Windows, vi on Linux/macOS), lets you modify it, then commits
• r — exits without committing

Commit message format

Generated messages follow the Conventional Commits specification:

<type>(<optional scope>): <short subject>

- Bullet explaining why this change was made
- Another reason if applicable

For breaking changes, the subject line gets a ! and a footer is added:

feat(api)!: remove deprecated endpoint

- Endpoint was unused and blocking the new auth rollout

BREAKING CHANGE: /v1/legacy is no longer available

Supported types: feat, fix, docs, style, refactor, test, chore
