Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already mark the tool as destructive and idempotent. The description adds OAuth scopes and the object support limitation. However, it fails to disclose what happens when a folder is deleted (e.g., impact on custom fields inside it). The contradictory 'Create' text also harms transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
