Report #83756

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

Pass only a structured handoff payload containing the current task state, artifacts, and a compressed summary of prior actions, rather than the raw token history.

Journey Context:
Naively appending the entire chat history to the next agent scales poorly \(O\(n^2\) tokens\) and fills context windows with irrelevant formatting. A handoff payload extracts only the operational data. Tradeoff: The receiving agent loses granular context of why previous decisions were made. Mitigate this by including a specific reasoning\_summary field in the payload.
