Does this skill support Pydantic v2 features?

Yes, it is fully optimized for Pydantic v2, including modern features like ConfigDict, model_validator, and field_serializer.

Can this skill handle complex, nested data structures?

Absolutely. It includes patterns for defining nested models and correctly using model_rebuild() for complex relationship handling.

What anti-patterns does this skill prevent?

It proactively flags and corrects common mistakes such as using mutable defaults in models, missing Optional type hints for nullable fields, and redundant manual validation logic.

How does it help with API development?

It provides standardized patterns for creating API request and response models that integrate seamlessly with frameworks like FastAPI to provide automatic validation and documentation.
