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 only implicitly indicates that requestId refers to the transaction request being read ('for one transaction request'), but does not elaborate on format or meaning beyond the schema, which already specifies uuid format. The single parameter is self-explanatory, but little added value.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
