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 for undocumented parameters, but it adds no meaning beyond what the parameter names already imply. The phrase 'from a run' weakly maps run_id to a run and case_id to a test case, but there is no detail on types, relationships, or expected value semantics. For a 0%-coverage schema, this is insufficient compensation.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
