Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses the authentication requirement ('only the holder of the secret can remove it') and implies a destructive action via 'Remove'. However, it does not detail side effects (e.g., immediate deactivation) or error behavior, making transparency partial.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
