Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotations already declare readOnlyHint=true, and the description's 'Detect' is consistent with that, so there is no contradiction. However, the description adds no behavioral context beyond the annotation, such as what a successful or failed detection looks like or what the returned status actually contains.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
