Implements robust, type-safe data validation and API modeling using FastAPI and Pydantic v2.
This skill empowers Claude to architect production-grade FastAPI applications by leveraging advanced Pydantic v2 patterns. It provides comprehensive guidance on creating complex data models, implementing custom field and model validators, handling nested structures, and securing APIs through strict request and response validation. By following these implementation patterns, developers can ensure their APIs are self-documenting, type-safe, and resilient against malformed data inputs.
