> think of our CLI agent as a built-in mux’er across agent sessions. This allows more natural interactions, like being able to switch directories in agent sessions, have the agent drive full-screen terminal commands (e.g. sqlite and mysql), and even run across ssh sessions with no remote binary install.

Looks like they let you use your LLM of choice on anything your terminal can SSH into using their TUI without having to install Claude Code or their agent on a remote system. Also, you are able to have multiple shell instances as you would on tmux in one session, all with the LLM fully aware of each one (not sure if its a model per session, or multiple, or what).
