Report #83935
[frontier] Agent enters infinite loop or cascading failure mode without detection during reasoning chains
Implement circuit breaker pattern: monitor output entropy/quality; trip to fallback after N consecutive low-entropy or duplicate outputs
Journey Context:
Agents can get stuck repeating the same tool call with slightly different parameters, or generating hallucinated plans. Simple timeout isn't enough. The circuit breaker tracks 'cognitive stutter'—high similarity between consecutive outputs or tool arguments. When tripped, switches to a simpler fallback agent or human handoff. Prevents API cost explosions and log spam from runaway loops.
