I've been using something like this with shelloracle

Nice ideas! I've been using the `?` shortcut in atuin [0] which accomplishes the same sort of thing, but these days also has access to an Agent-like experience which allows me to prompt something like "Conventional Commit message for unstaged changes" and it will call `git diff` (after asking permission, of course) and then generate the commit message.
