Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description creates a new lawsuit but does not disclose side effects, required authentication, non-idempotency, return values, or error behavior. Annotations provide only default false hints, leaving the description to carry the behavioral burden, and it does not go beyond the simple 'Cria' wording.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
