Report #53330

[architecture] Passing full conversation histories between agents causes context window overflow and high latency

Pass structured state objects \(scratchpads\) or summaries between agents instead of raw message histories.

Journey Context:
Naive multi-agent frameworks just append the entire message list when handing off. As the task grows, token limits are hit, costs explode, and the LLM gets confused by irrelevant history. A shared structured scratchpad allows agents to read/write specific state variables \(e.g., status and data keys\) without needing the entire conversational context.
