Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The verb 'muestra' (shows) implies a read-only operation, and the phrase 'asociados a tu cuenta' indicates data is scoped to the authenticated user. Since there are no annotations, this description provides the necessary behavioral context for a safe listing tool.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
