Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is known. The description adds that results contain psychological analysis, emotional significance, and waking-life connections, which gives some context about the response content. It does not cover auth, rate limits, pagination, or other behavioral details, but with annotations present the description does enough to justify a baseline 3 and contains no contradiction.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
