Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the behavioral disclosure burden. The word 'Devuelve' implies a read-only operation, which is minimal transparency, but it does not state possible errors, token requirements, or what 'revisión/configuración' precisely entails. It is acceptable but thin.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
