Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotation readOnlyHint already establishes that this is a read-only operation. The description's use of 'List' reinforces that but adds no additional behavioral context, such as pagination, ordering, or what exactly constitutes a 'scheduling page'. No contradiction exists, but the description adds no transparency beyond the annotation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
