Report #13552

[architecture] Handoff fails or degrades because the receiving agent's context window is overwhelmed by the sender's full history

Summarize or filter context during handoffs. Pass only the specific instructions, required parameters, and a concise summary of the conversation history, rather than the entire token stream.

Journey Context:
When Agent A hands off to Agent B, developers often pass the entire messages array. This quickly consumes Agent B's context window with irrelevant formatting or past tool calls that B doesn't need, degrading its reasoning ability and increasing latency/cost. The handoff mechanism must act as a context boundary. Agent A should synthesize a 'briefing' containing only the objective, constraints, and necessary data for Agent B to execute, effectively compressing the context while preserving high-signal information.
