Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, covering safety. The description adds the bulk support feature (accepting 'empresa_ids') and restates the operational purpose. It does not describe return format or edge cases, but adds meaningful context about batched execution beyond what annotations provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
