I think it's trying to be like a code-first/API alternative to Tmux. So instead of:

``` tmux new-session -d -s a

tmux send-keys -t a 'npm test' Enter

sleep 2

tmux capture-pane -p -t a ```

  you'd do something like:

``` pane.send_text("npm test\n").await?;

pane.wait_for_text("Tests passed").await?;

let snapshot = pane.snapshot().await?; ```

  I don't know why it would be better for agents, maybe the author also works on an LLM agent harness.
