Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, so description fully compensates. It clearly documents state format (two-letter abbreviation), county_fips format (3-digit code with example '037'), and year (default 2021, range 2012-2021). Every parameter is explained with concrete details.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
