Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The readOnlyHint annotation is true and the description's 'Search' is consistent with a read-only operation, so there is no contradiction. However, the description adds no behavioral context beyond the annotation, such as pagination behavior, result format, or that multiple results are returned.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
