Report #16031

[research] Agents get stuck in infinite loops of calling the same tool or repeating the same thought, consuming tokens and stalling without failing the task explicitly.

Implement a circuit breaker in the agent orchestrator based on telemetry: if the agent calls the same tool with the same arguments consecutively, or if the step count exceeds a dynamic threshold, terminate the run and flag it as a 'loop failure'.

Journey Context:
Infinite loops are a classic agent failure mode \(e.g., 'I need to search... search returned nothing... I need to search...'\). Standard timeout-based error handling is too crude; it doesn't tell you why it timed out. By analyzing the trace telemetry in real-time or post-run, you can specifically identify loop patterns \(repeated tool calls, repeated LLM thoughts\) and categorize these failures distinctly, which is crucial for debugging prompt issues that cause the loop.
