Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description completely fails to compensate. It provides no explanation of the 'site' parameter (is this a URL, slug, or ID?), what the 'id' refers to (dashboard ID vs. site ID), or what structure is expected in the nested 'data' object (fields, types, required values).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
