With the coming changes in June, ACP will charge towards the same budget as claude -p and the Claude Code SDK (since it uses the SDK), so ACP no longer solves this. It's (I think) why Zed added "Terminal Threads" [1] to their agent workflow
The ACP budget change is so bizarre to me. If i was more adventurous with my subscription i'd be interested to see if you could intercept UI/input from CC TUI and render that in a native GUI without it being a TUI. That would be "interactive Claude Code" but you'd get a programmatic interface.
But that would be banned almost instantly i'm sure lol.
