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 for the 8 parameters (5 required) but explains none of them. "After readiness" only loosely maps to readinessToken, and no meaning is added for amountMinor/currency units, idempotencyKey behavior, or the languageMode/contentLanguage distinction. The burden shift required at 0% coverage is unmet.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
