Report #6993

[architecture] System prompt gets polluted by dynamically injected memories that contradict current instructions

Isolate memory injection from core system instructions. Inject retrieved memories as a distinct block using XML tags and explicitly instruct the agent to treat them as historical context that can be overridden by current user instructions.

Journey Context:
When memories are injected into the system prompt or mixed with instructions, the LLM might prioritize an old memory \(e.g., User prefers Python 2\) over a new direct instruction \(Rewrite this in Python 3\). By separating the base instructions from the retrieved memories, you establish a clear hierarchy: Current User > System Prompt > Retrieved Memories. This prevents stale preferences from hijacking the current task.
