Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% and the schema itself enumerates every allowed topic value (fitting, fabric, craft, care, occasion, rent_vs_custom, chinese_bridal, taiwan_history) plus the empty-default behavior. The description adds nothing about the topic parameter, so the baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
