Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description must compensate. It gives only terse definitions ('Number of control points', 'NURBS degree') and omits constraints such as valid ranges, minimum point counts, or the relationship between degree and point_count. It also mentions a 'controller' argument that is not present in the input schema, which could confuse an agent.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
