Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 100% for the single symbol parameter, so the schema already documents format and default (SOLUSDT). The description adds no symbol syntax, casing, or listing requirements beyond what the schema provides, so the baseline 3 applies; there is a mild mismatch between the schema's 'USDT perp' example and the description's 'Hyperliquid perp' framing.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
