Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It describes the output as ranked places with editorial notes, which implies a read-only operation, but it does not explicitly confirm no side effects, authentication needs, or rate limits. The name 'list_guides' and verb 'List' strongly suggest safety, but more explicit disclosure would improve transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
