Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description adds no behavioral context beyond the readOnlyHint annotation. It doesn't mention error cases, response format, or the fact that the request_id likely references a specific media request. While consistent with the annotation, it offers no 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.
