Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The input schema has zero description coverage, but the description fully compensates by defining sql as 'A single read-only SQL statement' and limit as 'Max rows to return (default 100, max 1000)', adding clarity, constraints, and defaults for both parameters.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
