Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden, but it only states the basic listing behavior. It adds the detail that sections are included, which is useful, yet it does not mention whether an active connection is required, how results are ordered, or any potential limitations. The read-only nature is implied by 'Lister' but not explicitly disclosed.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
