Report #48928

[architecture] Passing full conversation history between agents causes context dilution and hallucination

Do not pass raw conversation history during handoffs. Instead, perform a structured handoff where the delegating agent extracts only the intent, required parameters, and current state into a clean payload for the receiving agent.

Journey Context:
Naively passing the entire chat history to the next agent to 'keep context' fills the new agent's context window with irrelevant pleasantries, failed attempts, and out-of-scope instructions. This causes the new agent to lose focus on its specific task. A clean handoff requires a structured payload of the goal and current state, acting as a fresh, high-signal context window for the specialized agent.
