Leaving it informal means the contract lives only in documentation prose and developer intuition, is inconsistently enforced, and drifts between what the documentation says and what the code actually handles. JSON Schema provides a standard, machine-readable format for expressing data contracts that can drive validation, documentation, and testing from a single source of truth.</p>
