Report #11312
[research] Multi-agent systems lose context or hallucinate constraints during agent-to-agent handoffs
Implement trace-level evals specifically at the handoff boundaries to verify that the receiving agent's initial prompt contains all required constraints and no mutated facts from the sending agent.
Journey Context:
In multi-agent setups \(e.g., Orchestrator -> Coder -> Reviewer\), the handoff is the highest-risk point. The sending agent might summarize away a critical constraint \(like 'use Python 3.8'\), causing the receiving agent to fail. Standard end-to-end evals won't pinpoint the handoff as the failure point. By evaluating the message payload at the handoff, you catch context collapse early.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
