Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already disclose destructiveHint=true, so the description adds limited value by mentioning 'Requires destructive access.' It does add the 'backup access' requirement, but doesn't explain the operational impact of a restore (e.g., overwriting existing data), which would be useful for a destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
