Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100%, with both parameters described (companyId as UUID value wrapper, datatableCode as lowercase kebab-case). The description does not add parameter-level semantics, but the schema fully handles this, so the baseline score of 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
