Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description's 'Delete' aligns with the annotations' destructiveHint=true and readOnlyHint=false. It adds context about clearing sensitive data, but the annotations already cover the destructive nature. No additional behavioral traits (e.g., side effects, required permissions) are disclosed beyond the annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
