Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description's 'Delete' matches the annotation destructiveHint=true, so there is no contradiction. However, it adds little beyond the annotations: the destructive and idempotent hints are already provided in structured data, and the description does not disclose additional behavioral context such as permanence, cascading effects, or how deletion of an arbitrary static DNS entry is handled.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
