Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already provide readOnlyHint, idempotentHint, and destructiveHint=false, and the description does not contradict them. It adds useful access information by declaring 'Required scopes: databases:read', but it does not disclose what the response contains, whether pagination occurs, or any other behavioral detail beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
