Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, idempotentHint=true, openWorldHint=false and destructiveHint=false, so the safety profile is fully covered. The description adds the 'reviewed' curation signal and the breadth of template categories, but says nothing about result ordering, count, or pagination behavior; with an output schema present, return-format detail is not required. Modest value added on top of annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
