[architecture] Agent losing critical context or exceeding token limits when handing off a long conversation to a specialized agent

Do not pass raw conversation history. The handing-off agent must synthesize a structured 'handoff payload' containing only the goal, the current state, and the specific action required, using a predefined schema.

Journey Context:
Naively passing the entire chat history to the next agent seems like a good way to preserve context, but it leads to context window exhaustion and 'lost in the middle' syndrome, where the receiving agent ignores the actual task amidst irrelevant pleasantries. A structured handoff forces the sending agent to summarize and distill the exact necessary state. This trades the completeness of raw history for the high-signal density of a focused state object.
