Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations indicate destructiveHint=false and readOnlyHint=false, consistent with a non-destructive write operation. The description adds that the operation makes the set ready for migration, but does not clarify reversibility, side effects, or what happens to the set's contents. No contradiction with annotations.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
