- The article explains how to choose the right memory strategy for an AI agent using a decision tree.
- It identifies four types of agent memory: working (for session continuity), semantic (for stable facts), episodic (for evolving history), and procedural (for reusable procedures).
- A five-question decision tree helps classify information needs, covering persistence beyond turns, session survival, stable vs. evolving nature, retrieval methods, and learning procedures.
- Common pitfalls include mixing memory layers, overly aggressive trimming, and storing raw logs instead of distilled lessons.
- Memory layers should be combined based on the agent's specific needs, such as using semantic memory for user preferences and episodic memory for interaction history.
