Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already disclose destructiveHint=true and readOnlyHint=false. The description adds the requirement of 'server-settings' access, which is useful. However, beyond the annotation-confirmed destructive nature, it does not describe side effects (e.g., downtime, version changes) or reversibility, so only partial additional transparency is provided.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
