Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Without any annotations, the description bears full responsibility for behavioral disclosure. It only mentions a security requirement but does not describe the effects of enabling the API, such as whether it is reversible, what changes occur, or any side effects. This is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
