AI agents get stuck in 3-day loop, developer implements payload fingerprinting

By PulseAugur Editorial · [1 sources] ·

A developer encountered an infinite loop where two AI agents, a Coder agent and a Reviewer agent, repeatedly sent the same messages to each other for three days. Standard step limits in frameworks like LangGraph and CrewAI failed to detect this loop because each message, though identical in content, was considered a new step. The developer implemented a solution by hashing message payloads and tracking these hashes to detect repeated content, effectively identifying and stopping the loop. AI

IMPACT Highlights a critical need for robust loop detection in AI agent frameworks to prevent costly infinite feedback cycles.

    <p>I set up a Coder agent and a Reviewer agent last week. Simple loop. Coder writes code, Reviewer gives feedback, Coder fixes it. I went to bed at midnight.</p> <p>They were still going when I woke up.</p> <p>Not crashed. Not erroring. Just talking. Coder kept fixing the same th…
