Three Levels of Memory Evaluation

An agent’s memory capability is evaluated across three levels:

Basic recall – exact return of explicitly given information ("my participant number is 12345");
Multi-session lookup – linking information across different conversations (user has two cars – clarify which one to service);
Proactive servicing – discovering hidden connections between old facts (international flight booked → passport expires soon → warn).

The third level requires both “overview” and “detail.”
