Report #22264

[architecture] Passing entire conversation histories between agents, causing context window overflow and high latency

Use an episodic memory or summarization step during handoffs, passing only the structured 'delta' or a compressed summary of the prior state rather than the raw transcript.

Journey Context:
Naive multi-agent systems just append messages to a shared list. This quickly exceeds token limits and degrades the receiving agent's reasoning due to lost-in-the-middle effects. Agents only need the specific instructions and results, not the internal reasoning traces of other agents. Summarization or structured state extraction at the handoff boundary is critical.
