Nutlope/aicommits ? reverse-engineered prompt

Build me a command line app called AI Commits that looks at my staged git changes and writes a good commit message for me using AI.

I want it to be easy to set up, with a first run setup flow that helps me pick an AI provider, enter my API key, choose a model if needed, and pick a commit style like plain, conventional commits, gitmoji, or subject plus body. It should work from the terminal, let me generate one or a few message options, copy a message to the clipboard, or go ahead and commit for me after I confirm. It should also support excluding files, adding a custom prompt, and skipping hooks when needed.

Please make it support both the normal command line workflow and a git hook so I can just run git commit and have the message suggested automatically. If anything needs current provider docs or API details, look them up online.
