Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the burden. 'Guide to...' combined with the get_ prefix and the all-doc sibling setimplicitly signals a read-only documentation retrieval with no side effects, but the description never states what the returned guide contains (format, scope, or level of detail), and there are no annotations to cover the safety profile.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
