I'm working on a full blown terminal emulator called "terminal-use", or "tu" in short, for coding agents. It allows agents to operate fully fledged TUI applications including multiple windows, mouse control, etc. It can even self drive a NetHack session via Claude, if you want lol.

It's basically tmux for your coding agent, great for developing and debugging TUI applications as well, because now your agent has a closed feedback loop of applying changes and trying them out itself via tu.
