Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile and the closed-world scope are covered structurally. The description reinforces the closed-world scope ('the firm's published pages') and names the returned fields, but adds nothing about result limits, ordering, pagination, or what happens at the 25-item cap.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
