Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It indicates that cloning produces new IDs and that confirm is needed in safe mode, implying a potentially destructive action when safe mode is off. However, it does not disclose permission requirements, reversibility, side effects (e.g., whether the cloned element is inserted inline or appended), or what happens to the original element.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
