Does this skill support Pydantic v2?

Yes, it is specifically designed for Pydantic v2 and FastAPI 0.100+, ensuring compatibility with the latest data validation features.

Can it help with OpenAPI documentation?

Yes, it provides patterns for path parameters, query parameters, and response models that automatically generate clean Swagger and OpenAPI documentation.

Is it compatible with older Python versions?

This skill requires Python 3.10+ to take advantage of modern typing features like pipe-operator unions and Annotated types for dependencies.

How does it handle application startup and shutdown?

It utilizes the modern FastAPI lifespan context manager pattern for managing resource lifecycles, such as database connection pools and external clients.

API Development

Builds high-performance, production-ready REST APIs using modern FastAPI and Pydantic v2 best practices.

About

The FastAPI Patterns skill empowers Claude to architect and implement modern Python web services with precision. It provides standardized implementation patterns for dependency injection, asynchronous request handling, and robust data validation using Pydantic v2. By leveraging this skill, developers can efficiently scaffold new endpoints, implement sophisticated authentication logic, and organize large-scale applications into modular routers while ensuring strict type safety and OpenAPI compliance across the entire codebase.
