Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 0%, meaning neither parameter ('dataset_uri', 'extra') is documented in the schema. The description adds no information about these parameters—it doesn't explain what a 'dataset_uri' is, its format, or what 'extra' data might be used for. With two parameters and zero coverage, the description fails to compensate, leaving parameters completely unexplained.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
