Why this instead of a generic OpenAPI diff?

If you only need a complete OpenAPI diff, use a specialist tool. Release Guardian is for an agent or CI job that must evaluate several contract surfaces through the same JSON/x402 interface: MCP tools, common OpenAPI breaking changes, GraphQL, SDK exports, JSON Schema, webhook payloads and API responses. It reports only the engines that actually ran and returns UNSUPPORTED instead of inventing a safe result.
