Report #14633

[architecture] Agent performance degrades or fails as conversation history accumulates across multiple handoffs

Summarize or prune context upon handoff rather than passing the full conversational history to the next agent.

Journey Context:
Naively passing the entire message history from Agent A to Agent B quickly exhausts the context window and degrades the LLM's attention \(the 'lost in the middle' problem\). The receiving agent usually only needs the actionable payload and the outcome of the previous step, not the step-by-step reasoning. Implementing a summarization step during the handoff \(or only passing the last N messages plus the structured handoff payload\) keeps the context lean and focused.
