Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden of behavioral disclosure. The verb 'Get' implies a non-destructive read operation, and it mentions the specific data fields returned. However, it does not disclose whether the response is a list or single object, potential rate limits, or any other behavioral nuances beyond the basic read-only implication.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
