Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema provides only names and defaults with zero descriptions, but the description's Args section fully explains each parameter: days (recent N days, default 30, max 365), limit (max count, default 20, max 100), and type (enum values 'keyword' | 'capability' | 'all'). This completely compensates for the schema's lack of descriptions.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
