Show HN: Giz, AI Git commits with easy to modify system prompt (in 140 lines)
github.comI tried setting up an AI git commit tool this weekend and it was hell.
All the tools are either not maintained, outdated, or make it a total pain to customize the system prompt. All I wanted was simple AI commit messages, that I can customize!
Introducing Giz: A tiny, drop in replacement for `git commit`, with ai commit messages.
`giz commit` behaves exactly like `git commit` with one exception:
The commit message is AI generated when no `-m` or `--message` argument is passed. User is asked for confirmation first. Its behavior is otherwise identical.
Easy to modify system prompt:
The prompt is stored in a textfile located at: `giz prompfile`. The diff (`git diff --staged`) is pasted two newlines below whatever you put in this file.
Quickstart:
- `pip install giz`
- `giz set_openai_api_key <your-api-key>`
- `giz commit ...`
Go to the link to see a demo! Cool, I made something similar last week for automating conventional commits, using fish/gum/curl/jq with claude. Installed it on the path as git-cc so it could be invoked with `git cc [-a]`
