Nanobot will happily ssh to a host and do things on it. I'm sure that's just a skill away for pi or opencode.

Hand your agent a tmux session.

This might have changed but Warp was not able to do this without “warpifying” the SSH host.

I mean… Claude Code desktop will SSH into anything and start coding for ya. Which could sound horrifying but if you setup an isolated system for that specifically its not that horrifying.
