SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill outlines best practices for building FastAPI applications, covering async patterns, and Pydantic validation to help you create robust APIs faster and with fewer errors.

Core Features & Use Cases

Structured Project Layout: A clean project scaffold with modules for routes, services, models, and utils.
Pydantic Models: Strong data validation and serialization for request/response payloads.
Dependency Injection & Middleware: Clear DI patterns to improve testability and maintainability.
Async Patterns & Testing: Async routes, background tasks, and testing patterns to ensure reliability.
Error Handling & Settings: Consistent error responses and centralized configuration.

Quick Start

Start by wiring a minimal FastAPI app using the patterns shown above, then define a sample route that validates input with Pydantic and runs with Uvicorn.
