Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It only mentions authentication implicitly ('authenticated user') but fails to specify required permissions, rate limits, error conditions, or response format. This leaves significant gaps for a tool that likely returns sensitive user data.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
