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 mentions the units involved (Celsius, Fahrenheit, Kelvin) but doesn't explain the parameters (value, from_unit, to_unit) or their semantics (e.g., valid unit strings, numeric ranges). This adds minimal value beyond the schema's property names.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
