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 discloses the data source ('published by this site') and content nature ('ranked places with editorial notes'), making the read-only behavior implied. It does not describe response structure, pagination, or ordering beyond 'ranked,' but for a simple list tool this is acceptable.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
