[architecture] Receiving agent loses critical context or hallucinates after a handoff because the conversation history is too large or unfiltered

Summarize the executing agent's state into a strictly structured 'handoff payload' rather than blindly passing the entire raw chat history to the next agent.

Journey Context:
Passing the full conversation history between agents seems like a good way to preserve context, but it leads to context window dilution—the receiving agent gets confused by irrelevant back-and-forth, or hits token limits. The architectural pattern is to treat handoffs like API calls: the previous agent returns a typed response object \(summary, extracted entities, next steps\) which becomes the input for the next agent, shedding the conversational chaff.
