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, but it only hints at 'items' through 'add purchased items to ingredients on hand'. It does not clarify the meaning, format, or optionality of store, total, week_id, order_ref, or the add_to_on_hand switching behavior beyond the default.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
