Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description must carry the full burden of behavioral disclosure. It only states the listing scope ('tenant atual') and omits important behavioral details such as pagination behavior, default ordering, sensitive response handling, or read-only guarantees. The verb 'Lista' implies a read operation but does not explicitly disclose side effects or defaults.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
