WHY IT NEEDS A POLICY

Why memorize_conversation needs a policy

This tool stores conversation data into a memory system, which is a write operation (creating new records). It is reversible in principle (memories can be deleted), so it doesn't qualify as Destructive. The blast radius is medium because misuse could store sensitive or manipulated conversation content that influences future AI behavior.

From the tool's definition 'Store a conversation in memory for future reference' — creates/writes new memory data
