SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill addresses the inconsistency and technical debt often found in FastAPI projects by providing a standardized, production-ready architecture that enforces clean separation of concerns.

Core Features & Use Cases

  • Architectural Blueprint: Implements a robust project structure with clear separation between routers, services, models, and schemas.
  • Production Patterns: Includes best practices for dependency injection, async database operations, transactional service layers, and Pydantic v2 validation.
  • Use Case: Use this skill to bootstrap a new backend service or refactor an existing one to ensure it follows industry-standard patterns for authentication, testing, and configuration management.

Quick Start

Apply the fastapi-patterns skill to generate a structured project layout and implement the recommended service layer and dependency injection patterns in your current directory.
