Report #56449

[architecture] An agent loses its specialized behavior and adopts the persona or constraints of another agent after a handoff

Enforce strict context isolation by completely resetting the system prompt and context window upon handoff, passing only the minimal required data payload, rather than appending the previous agent's chat history.

Journey Context:
To maintain continuity, developers often pass the entire chat history from Agent A to Agent B during a handoff. Because LLMs are highly susceptible to instruction-following in the context window, Agent B reads Agent A's system prompt and constraints, leading to persona drift \(e.g., the DB agent suddenly starts trying to write frontend code because it saw the frontend agent's instructions\). The tradeoff is that you lose conversational continuity, but you gain strict behavioral guarantees. Pass structured state, not conversational history.
