I was so blown away I just wrote a chat-based integration to vim / neovim (https://github.com/pasky/claude.vim) for it - actually, 95% of the 600 LoC is written by Claude. It is finally on a level where "pair programmer" becomes a way better UX than the "code completion" paradigm.

(BTW I think with some further AI-assisted work and using the tools interface, you could mostly match all the web interface features in an integration like this. And using API is less brutally rate limited.)
