Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema coverage is 0%, so the description must compensate. It describes the 'code' parameter as 'The Python code to score', which adds slight context beyond the schema's type definition but does not explain expected format, size limits, or encoding. The baseline for 0% coverage and 1 param is 4, but the added value is minimal, so 3 is appropriate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
