Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=false, destructiveHint=false, etc., indicating this is a non-destructive action. The description adds minimal behavioral context by mentioning it's 'useful for drag-and-drop operations' and returns a confirmation string, but doesn't elaborate on side effects, permissions needed, or error conditions beyond what annotations provide.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
