It’s just called ai-code I’m new to eMacs so this popped up but had a bunch of issues I was trying to debug https://github.com/tninja/ai-code-interface.el

Never heard of that one. The most popular ways for agent stuff seems to be https://github.com/xenodium/agent-shell , or just opening a terminal in emacs and using claude code. If you want to run it through an emacs terminal, consider using https://github.com/dakra/ghostel#ghostel (or vterm, or eat)
