Report #42887
[research] Agent loses context or hallucinates state during multi-agent handoffs
Implement trace-level evals that assert the exact schema of the handoff payload. Use a strict context envelope pattern where the receiving agent validates the payload against a JSON schema before proceeding, and log the diff if rejected.
Journey Context:
Agents passing messages often drop critical variables \(like user\_id or session\_state\) or hallucinate new ones. Relying on the LLM to figure out the handoff leads to flaky workflows. Structured handoffs with schema validation at the trace level allow you to pinpoint exactly which agent corrupted the state.
