Report #43000

[synthesis] Small error in Agent A output gets amplified through Agent B and C handoffs as each agent confidently resolves ambiguity in the wrong direction

At each handoff point, include an explicit typed schema contract that the receiving agent must validate against. Add a handback verification step where the receiving agent paraphrases its understanding back before acting, and the sending agent confirms. Never rely on natural language handoffs without structural validation.

Journey Context:
In multi-agent systems like Swarm, AutoGen, or CrewAI, handoffs are the highest-risk moments. The common assumption is that passing a clear natural language description is sufficient. In practice, natural language is inherently ambiguous, and each receiving agent resolves ambiguities based on its own context and training, not the original intent. This creates interpretation drift that compounds with each handoff—similar to the telephone game but worse, because each agent adds confident reasoning on top of the misinterpretation. The fix combines two patterns: structural contracts \(typed schemas that reduce ambiguity\) and handback verification \(the receiver confirms understanding before acting\). The tradeoff is latency and token cost per handoff, but this is far cheaper than the cascading errors that result from unvalidated handoffs. This synthesis requires holding Swarm's handoff model, AutoGen's conversation patterns, and information cascade theory simultaneously—no single framework documentation identifies this compounding effect.
