Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
With 0% schema description coverage, the description must carry parameter meaning, but it only explains productId ('by productId') and says nothing about the required idempotencyKey or how it should be generated/used. The name hints at its purpose, but the required parameter is left undocumented.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
