Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so the description is the only source of meaning for the 'csv' parameter. It adds concrete semantics by enumerating accepted column aliases and stating auto-detection. It does not clarify whether 'csv' is raw text, a file path, or a URL, nor does it mention delimiter or header expectations.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
