Report #76553

[architecture] Agent handoffs fail or degrade in performance because the entire conversational history is blindly passed to the next agent, exceeding context limits

Summarize or filter the context during handoff, passing only the structured intent, required parameters, and relevant history, rather than the raw token stream.

Journey Context:
It is tempting to pass the full message history to the next agent to keep them informed. However, this includes irrelevant tool outputs and conversational filler. The receiving agent only needs the specific task payload. Summarization or structured state extraction at the boundary preserves context window space for the actual task.
