Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, fully covering the safety profile in structured data. The description adds the content scope of searchable memory (facts, decisions, preferences, commitments) but discloses no further behavioral traits such as result freshness, memory coverage limits, or exclusivity of long-term memory. It adds modest value beyond the annotations, earning a 3.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
