Agent Systems
Agent Memory
Memory is not remembering everything. It is deciding what remains useful after the current conversation ends.

Agent memory is often described as a storage problem. It is better understood as a policy problem.
Context is not memory
Context is working material for the current task. Memory is information deliberately retained because it should influence a future task.
Three useful kinds
Semantic memory records durable facts. Episodic memory records what happened. Procedural memory records how work should be done.
Remember less, better
A system that saves every detail becomes noisy and untrustworthy. Good memory has a write policy, an update policy, and a forgetting policy.
