You leave your Mac for five minutes. Codex hits one tiny question, and the whole run waits there.
Leave the desk. Keep the loop.

Looper keeps your coding agent loops alive on the Mac, tracks the right thread, and brings the next decision back to you when the run needs steering. Start a task, step away to swim, cook, paint, fish, or take a real break from the screen, then continue from the same loop instead of coming back to a terminal that has been waiting the whole time.
