AI agents get stuck in hallucination loop, wasting 470 generations

A company running numerous AI agents discovered a significant issue where a reviewer agent repeatedly rejected a producer agent's work due to hallucinated requirements. This occurred because the reviewer agent was not provided with the original request, leading it to invent criteria like "output 3 lines only" which conflicted with the producer agent's contract for a minimum of 600 characters. The system's retry mechanism failed to break the loop, resulting in approximately 470 wasted AI generations. The company has since implemented fixes, including passing the original request to the reviewer, declaring document truncations, and adding a human review after a set number of consecutive failures.
