Report #59432
[research] Multi-agent handoffs silently lose context or loop infinitely without failing the overall task
Implement trace-level evals that check for cyclical handoffs \(Agent A -> B -> A\) and context window saturation. Add a handoff validator step that asserts the receiving agent actually possesses the required state variables before execution begins.
Journey Context:
Outcome-based evals \(did the task finish?\) miss silent degradation where agents pass the buck back and forth, eventually solving it by accident or timing out. People assume the orchestrator handles state, but context is often dropped during serialization between agents. Evaluating the trace \(the sequence of spans\) catches loops and missing state that final-answer evals miss.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
