- I don’t get these kind of tools. A commit should be the why of a change, not a summary of what it is, anyone can either get that themselves or just read the code if they desire. What you can not get from the code is the _why_ which only you as the author can put.
- There's three types of people: those who already write excellent commit messages explaining the why, those who write decent ones explaining the what, and those who write garbage commit messages. Empirically, the first set is small. This tool will help the middle type be more efficient, and help the last type drastically.
Well done OP.

- Neat project. If you're looking for something simpler just to use w/ Claude Code, a simple call to "claude -p" can work: https://github.com/nicksergeant/dotfiles/blob/master/zshrc#L...
- Chiming in with my alternative, like others' but uses simonw's `llm`:
git upstream-diff | llm --system-fragment cl-description.md
However, in practice, I notice the generated messages focus more on the what than the why. So it's rare I use them verbatim.
- I've been using LMStudio to run a local LLM (Qwen3-4B) to generate commit messages using this command:
```
git diff --staged --diff-filter=ACMRTUXB | jq -Rs --arg prompt 'You are an assistant that writes concise, conventional commit messages. Always start with one of these verbs: feat, fix, chore, docs, style, refactor, test, perf. Write a short!! message describing the following diff:' '{model:"qwen/qwen3-4b-2507", input:($prompt + "\n\n" + .)}' | curl -s http://localhost:1234/v1/responses -H "Content-Type: application/json" -d @- | jq -r ".output[0].content[0].text"
```
- Hey all - disclaimer I'm one of Cell's friends and encouraged them to release their utility on Pypi for others. It quickly became one of my favorite tools that I use every day.
`git commit` is gone, `uvx gac` is in!
- Here's the 20 line bash version I whipped up a while back cuz yes lazy about writing good commit messages.
Supports claude and gemini with model selection and goes into the githook such that when you type `git commit` it invokes and generates the message.

- That's very cool! I actually built a Claude Code Web alternative* over the last few months and made my own auto-commit solution for it. I reckon though having the prompt is what helps me and the agent generate relevant prompt messages that can explain the why.
Anyway even a average commit message is way better than none

- "gac" is giving me PTSD flashbacks from having to deal with the "Global Assembly Cache" aeons ago.

- I like that you’ve added secret detection and multi-provider support — that’s something most LLM commit tools miss.
Have you benchmarked latency differences between local models (like Ollama) and OpenAI/Anthropic? Would be interesting to see a speed comparison.

- > Automatic secret detection: Scans for API keys, passwords, and tokens before committing
Surely this is done on-device right? Or is the prompt asking the LLM if there are secrets in the changes.
Arguably I trust Github / Gitlab / etc more than OpenAI / Anthropic / etc
- Oh nice. Man I hate filling out all that stuff. And getting the LLM to do it without freestyling and hallucinating is a pain. Kinda wish it were an MCP so I can shove it in my CLI or maybe the hooks for git...
- Hate writing commit messages.
Just installed gac; they nailed the UI/UX.
And so far, it works quite well.

- Maybe it's because these days I use perforce more than git but I tend to find myself writing 80% of my commit message before I write any code and touch it up a little at the end.
- I like the lazycommit+lazygit combo.

- Very neat little project, I look forward to trying this
- aicommit2 works great: https://github.com/tak-bro/aicommit2
Getting started is as easy as installing claude/codex/gemini: npm install -g aicommit2
I'm excited to give gac a try and see how it stacks up! The steering hints with gac might give it an edge.

- This misses the point of what a good commit message is so much that it could be a delightful satire.
