Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare destructiveHint=true and idempotentHint=true, so the destructive nature is covered. The description adds little behavioral context beyond what annotations provide, though it clarifies that it deletes stored memories and suggests use cases, but no extra behavior details are disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
