Sometimes the browser is the wrong tool. You want your own prompt, your shell history, your tmux config, your editor with your bindings. Or you need to grep a half-gigabyte log without watching it scroll past in a web page.
Every workspace container in Loopyard listens on a local SSH port. From your own terminal:
ssh -p 2222 container-name@localhostThat lands you in the same session the agent is in. If it is running a command when you connect, you watch it run. If you tail a file and the agent writes to it, you see the writes as they happen.
Edit a file from your shell and the agent sees your edit. Have the agent edit a file and you see it in your shell. People work in terminals and so do agents, so they may as well share one.
