Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already mark this as read-only and non-destructive, and the description does not contradict them. It adds the 'before/after example gallery' context but does not disclose additional behaviors such as default unfiltered listing, pagination, or how the optional theme affects results.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
