Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotation readOnlyHint=true is consistent with the description's 'List' operation, so there is no contradiction. However, the description adds no extra behavioral context beyond the annotation—no mention of pagination, response scope, or any constraints. It does not add value beyond what annotations already provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
