Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100% and both enums (kind, field) are documented in the schema, so the schema carries the parameter burden. The description only loosely maps to kind via 'wrong, or ask it off' and says nothing about domain, email, suggested, or note beyond the schema text. Baseline 3 applies.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
