Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations declare readOnlyHint=true, and the description is consistent with a read-only search operation. The description adds a useful behavioral constraint that results are limited to the authenticated account's uploaded media. However, it does not disclose other behaviors such as return format, pagination details beyond schema, or any side effects. With the annotation covering safety, the description provides minimal added value beyond that.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
