Report #57365

[research] Agent handoffs lose context or loop infinitely between delegates

Attach a handoff\_count and parent\_span\_id to every trace span, and set an eval threshold alarm if handoff\_count exceeds a maximum for a single task, or if a cyclic dependency is detected \(e.g., Agent A delegates to B who delegates back to A\).

Journey Context:
Multi-agent systems often suffer from 'ping-pong' handoffs where agents bounce tasks back and forth without progress. Standard latency metrics don't catch this. Tracking the span graph depth and cyclic dependencies in traces allows you to cut off infinite loops and evaluate routing logic efficiency before token limits are exhausted.
