About this skill

Backend Python Skills

Provides full-stack capability support for Python backend development.

🤖 Agent & MCP Enhancements

This Skill supports and recommends use with specific agent roles and MCP tools for best results.

Recommended Agent Roles

  • Python Backend Expert: See AGENTS.md。
    • This role focuses on FastAPI, asynchronous programming, and performance optimization.
    • When enabled, the AI will prioritize using Pydantic for type validation and focus on asynchronous performance.

Recommended MCP Tools

  • PostgreSQL/MySQL MCP: Directly execute SQL queries for validation and obtain real-time Schema information.
  • mcp-feedback-enhanced: When designing APIs or database structures, proactively confirm business requirements with the user.

Included Skill Modules

1. FastAPI Templates

  • Core Value: Quickly build high-performance modern Web APIs.
  • Key Technologies: Pydantic validation, dependency injection, OpenAPI documentation.
  • Use Cases: Microservice development, API gateway construction.

2. Python Performance Optimization

  • Core Value: Improve the execution efficiency of Python code.
  • Key Technologies: Profiling, multiprocessing/multithreading, algorithm optimization.
  • Use Cases: Compute-intensive tasks, high-concurrency services.

3. Asynchronous Python Patterns

  • Core Value: Master asyncio and write efficient non-blocking code.
  • Key Technologies: async/await, coroutine management, asynchronous I/O.
  • Use Cases: I/O-intensive services, real-time communication.

4. Python Testing Patterns

  • Core Value: Establish a solid automated testing system.
  • Key Technologies: Pytest, Mocking, Fixtures。
  • Use Cases: Unit testing, integration testing authoring.

Practical Scripts

Initialize FastAPI Project

# 创建新项目
python scripts/init_fastapi_project.py my_project --path ./projects

How to Use

  • API Development: "Please use the FastAPI template to help me create a user registration endpoint."
  • Concurrency Optimization: "Please refer to the Asynchronous Python Patterns to help me optimize this web scraping script."
  • Project Initialization: "Help me initialize a FastAPI project, the project name is user_service."
