I've got a wrapper around tmux for an audience of one. I can operate claude code, codex, opencode, or just a shell, from any of my devices to any of my devices (via tailscale) or more commonly, operate it on my exe.dev server.

I often continue a session on my phone, sometimes with voice. I have buttons for viewing files or following links the agent has referenced, extracted from the stream of text, and I have some buttons for exactly the git stuff I need. I have a button to toggle between yolo mode and normal.

Basically, very simple UI for everything I actually use, easy to use on a phone - and maybe more importantly, no UI for anything I don't personally use. Also all my machines have the repo for the uh, harness-harness, so I just open the tab for it if I need some changes and prompt them into existence and get the changes live.

All this is great, except it enables me to work every waking hour of my life. That part might be bad.
