Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the behavioral disclosure burden. It clearly signals a read-only operation through 'Retrieve' and the explicit 'GET' method, which is a strong transparency indicator. It does not mention error behavior or permissions, but for a simple fetch these are minor gaps.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
