Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description must carry the burden of behavioral disclosure. It conveys that the operation is a read (List) and scoped to the authenticated athlete, but it does not mention pagination, required OAuth scopes, rate limits, or response format. This is basic transparency but not comprehensive.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
