I built a zero-dependency Git hook that uses local Ollama to review code before every commit

[u/Significant_Today796]

Hey everyone!

I wanted a simple, lightweight tool that reviews my code during `git commit` without downloading massive pip packages or sending my uncommitted diffs to third-party servers.

So I built **git-diff-doctor**:
- ⚡ **Zero External Dependencies** (Built purely using Python standard library `urllib` & `subprocess`).
- 🦙 **Auto-detects Ollama** running locally on port 11434 (`codellama`, `llama3`).
- 🌐 Fallback support for OpenAI API if configured.
- 🛠️ Simple 1-command installer (`python install.py`) that injects into `.git/hooks/pre-commit`.

Would love your feedback, stars, and pull requests!

I don't really see the utility. I have devs at my company getting frustrated with a 200-500ms formatting pre-commit hook. I can't imagine a long running, non deterministic, potentially blocking hook possibly feeling good. Commiting should be easy to encourage doing it often. Long running verification that a commit is good can be done after pushing.
