**Automated Documentation and Commit Message Generation for Every Git Commit**

AI coding agents are powerful but stateless—they lack context on why a change was made. This leads to guesswork and bugs.

While most "AI commit" tools stop at the message, CommitLM is an AI-native git tool that creates a tiny, structured docs per commit. This acts as a **briefing for LLM coding agents** (like Copilot, Gemini CLI, Claude, etc.), so they can:

• ✅ Pick up exactly where you or another agent left off.
• 🧠 Respect constraints and project-specific nuances.
• 🔄 Update callers, tests, and migrations with fewer misses.

pip install commitlm
commitlm init
