Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description repeats the readOnlyHint annotation by saying 'Read-only,' and no behavioral context beyond that is added (no return shape, pagination, or side effects). It is consistent with the annotation, so there is no contradiction, but the description contributes little extra transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
