Synchronizes API specifications with implementations, detects breaking changes, and generates type-safe client code for frontend and backend alignment.

The API Contract Sync Manager is a specialized skill for Claude Code designed to bridge the gap between API documentation and codebase reality. It automates the validation of OpenAPI and GraphQL schemas, cross-references documentation against actual endpoint implementations to find coverage gaps, and protects against regression by identifying breaking changes between versions. By facilitating the generation of TypeScript interfaces and API clients directly from specifications, it ensures that frontend and backend teams stay perfectly aligned while maintaining high standards for API versioning and documentation.
