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. It adds meaningful semantics for all three parameters: 'code' as '港股代码 (如 'hk.00700')' (Hong Kong stock code, e.g., 'hk.00700'), 'year' as '4位年份 (如 '2023')' (4-digit year, e.g., '2023'), and 'quarter' as '季度 (1, 2, 3, 或 4)' (quarter: 1, 2, 3, or 4). This clarifies format and constraints beyond the bare schema, though it doesn't explain edge cases (e.g., invalid codes).
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
