[research] Agent gets stuck in an infinite tool-calling loop without failing

Implement a circuit breaker in your observability layer based on step count and repeated tool calls. Emit a specific telemetry span attribute \(e.g., loop\_detected=true\) when the agent calls the same tool with similar arguments consecutively, and halt the run.

Journey Context:
LLMs occasionally get stuck in loops, especially when an API returns an unexpected error format or subtle state change. The agent retries, gets the same error, and retries indefinitely. Standard timeout limits are too coarse; the agent consumes tokens rapidly while technically 'working'. Detecting identical consecutive tool-call spans allows you to terminate the trace early, saving costs and flagging the specific tool failure for debugging.
