Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. 'Get' implies a read-only operation, and the description adds the useful behavioral detail that the response includes a download URL. However, it does not disclose response format, pagination, or any other side effects, which is adequate for a simple get but not rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
