Report #11306

[architecture] Retrieved memories override current system prompt instructions

Place retrieved memories in a distinct XML block or markdown section in the prompt, and explicitly instruct the agent in the system prompt that retrieved context is supplementary and should be discarded if it contradicts current task constraints.

Journey Context:
LLMs suffer from recency bias and anchor heavily on provided context. If a large block of retrieved memory is injected, the LLM might treat it as absolute truth, even if it's outdated or contradicts the current system prompt. Structuring the prompt with clear boundaries \(XML tags\) and explicit precedence rules \(System > Current User > Retrieved Memory\) mitigates this anchoring effect and stops old state from hijacking new instructions.
