Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true and idempotentHint=true, which the description does not contradict. However, the description adds no behavioral context beyond the annotations—no details about return format, whether the export is synchronous, any authentication requirements, or what 'export' actually produces (e.g., a file or data payload). The description does not go beyond the basic operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
