Report #12465

[architecture] Receiving agent adopting the wrong persona or hallucinating due to leaked system prompts from the sending agent

Strip the sending agent's system prompt and persona during handoffs; pass only the objective, the structured payload, and the minimal required conversational history.

Journey Context:
When an agent hands off a task, developers often pass the entire chat history. This pollutes the receiving agent's context window with instructions meant for the sender, causing the receiver to act out of character or get confused. Handoffs must be surgical data transfers, not raw chat dumps. The new agent should rely on its own system prompt and the distilled context of the task.
