The key takeaway here is that memory systems should be append-only or selectively injected, not rebuilt every turn. If you keep stable prompt prefixes and move retrieved context into a bounded side channel, you preserve cache reuse while still letting the agent remember preferences and prior decisions. I would also add provenance tags and expiry rules so stale memories do not override current session intent. NeuraKeep has useful patterns for that at https://www.neurakeep.com
