Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the full burden of behavioral disclosure. It does disclose the key behavior of returning a Zip file containing a recipe and its original image, and 'Get' implies a read operation. However, it does not mention token validity, authorization requirements, whether the operation is read-only, or what happens for invalid/expired tokens, so transparency is partial.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
