Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already indicate this is a write operation (readOnlyHint false) and not destructive (destructiveHint false). The description adds no substantive behavioral detail beyond these annotations—no mention of error handling, idempotency, duplicate folder behavior, or whether parent folders are auto-created. The example path only addresses parameter format, not tool behavior.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
