Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 75%, so most parameters (limit, intent, unitId, frqType, subjectSlug, courseVariant) already have descriptions. The tool description adds value for the undocumented excludeIds by mentioning 'excluded IDs' and contextualizes cursor via the pagination statement. It does not, however, elaborate on parameter formats or valid values, so it compensates only partially for the 25% coverage gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
