Report #35502

[architecture] Passing entire conversation history during agent handoffs causes context overflow and high token costs

Pass only a structured summary or specific state variables \(context variables\) during handoffs, not the raw message log.

Journey Context:
Naively, you want the next agent to have full context by passing the entire chat history. This quickly hits token limits and confuses the receiving agent with irrelevant formatting from previous steps. Passing a structured dictionary of state \(e.g., \{"customer\_id": "123", "issue\_type": "refund"\}\) keeps the context lean and actionable, though it requires upfront schema design.
