Report #92083

[architecture] Passing the entire conversational history between agents causes context window overflow and attention dilution

Implement a state summarization step at the agent boundary, passing only the structured output and a distilled summary of the prior context to the next agent.

Journey Context:
A common anti-pattern is passing messages\[\] wholesale from Agent A to Agent B. This quickly hits token limits and degrades the LLM's attention on the actual task. By forcing Agent A to output a structured 'handoff document' \(state \+ summary\), you keep the context lean and focused. Tradeoff: Summarization is lossy; nuances from the original prompt might be dropped. Requires careful schema design for the handoff document.
