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. It adds no meaning beyond the schema, failing to explain what 'code', 'year', 'quarter', 'limit', or 'format' represent (e.g., stock code, fiscal year, quarter number, result limit, output format). With 5 parameters and no schema descriptions, this is a major gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
