Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description explicitly says 'Deletar' and 'DELETE', which are destructive operations, but annotations set destructiveHint=false, directly contradicting the described behavior. The 'write, altera dados' note and bulk support add some context, but the contradiction forces a score of 1.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
