Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full responsibility for disclosing behavioral traits. It only warns 'use com cautela,' hinting at destructiveness but failing to specify consequences, reversibility, or impact on dependent items. The description adds minimal transparency beyond an implicit danger signal.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
