Report #65786
[frontier] Multi-agent handoffs fail due to context thrashing and hallucinated shared history
Use structured Handoff Packets instead of raw message history. When transferring control from Agent A to Agent B, Agent A outputs a strictly typed JSON object \(current state, summary of work done, next steps\) and discards the raw conversational context.
Journey Context:
Developers often pass the entire message history between agents, assuming more context is better. This causes the receiving agent to hallucinate based on A's internal reasoning, get confused by tool calls it doesn't have access to, and hit token limits. Passing raw history breaks encapsulation. Structured handoff packets enforce a clean API boundary between agents, treating them as microservices rather than threads in a single conversation.
