Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description covers 100% of the parameter, explicitly naming 'topic' as the guide topic to fetch, referencing list_guides, and enumerating all allowed enum values. The description adds the 'see list_guides' hint, making the parameter's meaning and accepted values fully clear.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
