Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It only states 'list with search/paging' but does not disclose behavioral traits such as authentication requirements, default sorting, rate limits, or what fields are returned. A listing tool should at least mention that it returns all accessible groups or that it's paginated (which is implied by paging params but not stated).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
