Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0% and the query object is deeply nested, so the description carries the burden of explaining the filter fields. It enumerates the semantic criteria (body, curve type, direction, exact length, center, bounds, adjacent faces), which maps to bodyIds, curveTypes, direction, lengthMm, center, boundsMm, and adjacentFaceIds, adding real meaning over bare property names. It still omits tolerance semantics, the line/circle booleans, and the required revision string.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
