Very exciting. I used claude-code-ide, but the fact that it's not using comint-mode is a PITA.

looking forward to trying this!

Can I ask. I haven't dug into the ACP spec. Does it cover the "ide" features too (like Claude code ide. Seems to mostly be telling the agent where your cursor is and diff integration)? Or just the basic stuff?

It's got some of them already like showing and accepting diffs rendered natively. All edits are committed via Emacs itself and on to open buffers if applicable. TAB navigation. Accepting permission has had a fair amount of iteration to smoothen the experience. It's been quite a bit of work to get here. There are obviously more feature to come. Please file feature requests if you find anything missing and of course, sponsor the project if you truly want it to be sustainable and move forward.
