[frontier] Multi-agent handoffs lose critical context or inject noise when passing raw conversation history between agents

Define a typed handoff schema for each agent transition. The sending agent populates the schema; the receiving agent gets only the schema object, not the raw conversation. Include: task\_summary, decisions\_made, remaining\_work, constraints\_discovered. The schema IS the contract between agents.

Journey Context:
Naive multi-agent systems pass entire conversation histories between agents. This causes context pollution \(Agent B sees Agent A's internal reasoning and tool outputs\), token waste, and confusion — Agent B tries to interpret Agent A's discarded approaches as current state. The emerging pattern uses structured handoff objects, essentially function signatures for agent transitions. OpenAI Swarm implements this via handoff functions that return a context object the next agent receives. The tradeoff: you lose nuance from raw conversation, but you gain clarity, token efficiency, and the ability to validate/type-check handoff data. This also makes agent topologies composable — you can swap agents in and out as long as they honor the handoff schema.
