Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
There is one required parameter, supply_id, with 0% schema description coverage. The phrase 'of an FBS supply' loosely implies that supply_id identifies the supply whose boxes are listed, but the description does not explain the expected format, source, or validation of the ID. This is only minimal compensation for the schema gap.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
