Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety and open-world profile. The description adds freshness ('Current') and a scope constraint ('public section' only), which is useful, but discloses nothing about volume, ordering, or country editions.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
