Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the burden. It states a 'new, independent copy' is created, implying no side effects on the original. However, it does not disclose if all attributes (e.g., versions, permissions) are cloned or any limitations, such as whether the copy is draft or published.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
