Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds value beyond that by disclosing the shape of what comes back (name, search, filter bar, and an opening link) in the absence of an output schema. It omits permission requirements and whether the view list is paginated.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
