tmux is still nice for remote work And it's even nicer when you want to have a different harnesses communicate with each other. I typically have a group of them working on the same thing, and typically it is Codex, Claude Code, and Pi. Sometimes I include agy if I need some Google specific capability, and it's very easy for them to communicate. I basically evolved something like a poor man's version of Claude Code's new projects But the nice thing is that I can have different coding harnesses other than cc working on a specific tasks.
