Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare this as read-only, open-world, idempotent, and non-destructive. The description adds useful behavior beyond that: it defines the output semantics (colegiado number, college, specialty, status) and scopes the domain to 24 Spanish verticals. There is no contradiction with the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
