Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description lacks behavioral details. It says 'Revoke' which implies a destructive action but does not mention permissions, side effects, or irreversibility. The 'confirm' parameter in the schema partially addresses this, but the description itself does not.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
