Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already cover the safety profile with readOnlyHint=false, destructiveHint=true, and idempotentHint=true, so the description does not need to restate those. It adds the useful ShareWatch accessibility precondition, but it does not disclose side effects like whether the source location is removed or how name collisions are handled.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
