Absolutely! Aider does most of this.

It notices if your local repo is dirty and asks if you'd like to commit before proceeding with the GPT chat. It will even provide a suggestion for the commit message.

You can run aider with --no-auto-commits if you don't want it to commit to the repo. This is similar to your suggested --dangerous flag.

I have considered various magic/automatic branching strategies. But I suspect they would be too confusing. And people probably have their own preferred git workflows. I feel like it's probably better to let folks explicitly manage their branches and PRs however they like.
