[frontier] Multi-agent handoffs lose critical context when agents pass natural language summaries to each other

Define typed schemas for inter-agent handoffs. When an agent transfers control, it must produce a structured handoff document with fields for: task\_specification, completed\_work, current\_state, dependencies, and constraints. The receiving agent consumes this typed document rather than parsing free-form conversation history.

Journey Context:
The default pattern in multi-agent systems \(including OpenAI Swarm\) is passing conversation history or a natural language summary during handoffs. This is lossy: the receiving agent must re-interpret ambiguous natural language, important details get dropped, and there is no schema to validate that required information was actually passed. Structured handoffs make the contract between agents explicit and machine-verifiable. You can validate handoff documents against schemas, reject incomplete handoffs, and trace exactly what information was transferred. The tradeoff is that defining schemas upfront requires more design work and makes the system less flexible—agents cannot ad-hoc communicate unexpected information. But in production, this constraint is a feature: it forces clear interfaces between agents, just like API contracts between microservices. The pattern works best when each agent has a well-defined role with known inputs and outputs. For exploratory tasks where output shape is unknown, natural language handoffs may still be appropriate.
