Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description coverage is 0%, so the description must compensate for parameter meaning. However, the description explicitly mentions 'line items', which clarifies the 'lines' parameter structure somewhat. It also says 'for a customer', which hints at 'partnerName'. But it does not describe 'reference' or 'partnerEmail', leaving those ambiguous. Given the 0% coverage, the description does provide some semantic value but not enough to fully compensate.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
