Report #8238

[architecture] Context window overflow caused by appending full inter-agent conversation histories during handoffs

Implement state summarization or structured state passing. Instead of passing the entire raw chat history to the next agent, pass only a structured 'handoff payload' \(e.g., current status, extracted entities, next steps\) generated by the departing agent.

Journey Context:
Naive handoff implementations simply append the previous agent's transcript to the next agent's prompt. This quickly exhausts the context window and dilutes the signal with conversational filler. By forcing the departing agent to summarize into a schema, you compress the state, maintain only high-signal data, and keep the receiving agent's context focused on the task, not the history.
