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 run_id. It doesn't: the description never mentions run_id, a run, or what the report will contain. The parameter name is self-evidently an identifier, but the description adds no semantic detail about how the run is resolved or what output is produced.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
