Report #55344

[research] Context loss or hallucination during multi-agent handoffs

Inject trace-level evals at handoff boundaries. Validate that the outgoing message payload from Agent A contains the exact required state \(e.g., task ID, user intent\) before Agent B initializes.

Journey Context:
Multi-agent systems fail at the seams. Agent A assumes Agent B knows the user's ID; Agent B hallucinates one. Standard end-to-end evals just see a failed task. By adding assertions on the trace spans at the exact handoff point, you isolate whether the failure is Agent A's output or Agent B's reasoning.
