What a Closed-Loop Coding Agent Actually Is
What a Closed-Loop Coding Agent Actually Is
Closed-loop control requires a feedback signal trustworthy enough to act on. Most AI coding agents close their loops on lossy sensors, tests, unsound types, model judgment, and inherit the instability that follows.
