Can you shed some light on the speed difference of the direct integration vs. ACP?

I’m still looking for a generic agent interaction protocol (to make it worth building around) and thought ACP might be it. But (and this is from a cursory look) it seems that even OpenCode, which does support ACP, doesn’t use it for its own UI. So what’s wrong with it and are there better options to hopefully take its place?

I've used ACP extensively because agent-shell in emacs uses it, although the Anthropic license change means I'm not sure if I can continue to use Claude through it without getting banned. I kind of wish it integrated more tightly but also you can't really expect someone to have magit involved such that agent-shell (or the like) starts interacting with emacs directly. I'd love it if it did though.

I've started using OpenCode for some things in a big window because its side-by-side diff is great.

Yeah, ACP adds another layer of marshaling/unmarshaling (or two-one on each side) and can be slower than API calls on occasion. Like MCP, it adds JSON overhead that doesn’t really need to be there.

The best option will always be in-memory exchanges. Right now I am still using the pi RPC, and that also involves a bit of conversion, but it’s much lighter.
