Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden of explaining behavior. 'Get' reasonably signals a read-only retrieval, and the single-resource scope is clear, but the description does not mention response contents, error behavior, or permissions. It is adequate for a simple fetch operation but leaves some behavioral details implicit.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
