Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover the safety profile: readOnlyHint, idempotentHint, destructiveHint false. The description adds the output composition (purpose, inputs, result, limitations, link), which is useful, but it does not disclose error behavior for invalid IDs or other runtime traits. This is acceptable given the annotations but not especially rich.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
