Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint: true, and the description 'List' is consistent with that. However, the description adds no additional behavioral context such as pagination behavior, sorting, or whether the response includes all fields. With no extra disclosure beyond the annotation, the bar is not met for adding value.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
