Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, and non-destructive behavior. The description adds the GET endpoint and the dual-type listing behavior, but does not describe pagination or return handling. Given the existing annotations and output schema, this is acceptable but not exceptionally rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
