Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0% and the single preparationId parameter has no schema description. The description names preparationId and implies it is a handle produced by a prior preparation step, but does not say where to obtain it or what its format is, so it only partially compensates for the coverage gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
