GH contains a demo.
These can be in different projects, and I also support opencode (though its tested less). Behind the scenes I use tmux and fancy ctrl+c, ctrl+v semantics and by installing an mcp which gives tools like ask, notify, list, whoami, etc. With a relay tunnel (repowire.io) you could have these peers across machines too.
I kept playing around and I realised i could turn a slack bot and a telegram bot into peers too, so now I can control my claude code sessions via a remote dashboard, or telegram.
Before you ask me, how it compares with - OpenClaw: Openclaw does way more - Gastown: Also does way more, less control over individual sessions - Claude remote control / dispatch: I built this before, and and the hope is to break free from <just> claude-code - Claude agent teams: I literally complained to Boris a week before teams came out on twitter saying this should be native to claude code.
