Load when reviewing code, writing code examples, or ensuring code quality.Contains coding standards for Python, JavaScript, SQL, and general bestpractices for publication-quality code.

Modern async ORM with type-safe models and efficient queries

Performs thorough code reviews focusing on quality, best practices, security, and maintainability. Use when user asks for code review, feedback on code quality, or wants suggestions for improvements.

Feedback-driven skill improvement through tool outcome analysis. Collects executiondata and surfaces insights for skill refinement. Use this skill when you want to:- Understand how skills are performing ("show skill feedback", "how are skills doing")- Get insights on skill effectiveness ("skill insights", "what skills need improvement")- Identify skills that need improvement ("which skills have errors")- Analyze tool usage patterns ("what tools are failing", "error hotspots")- Set up feedback collection ("enable feedback", "setup feedback tracking")

Use this skill when building MCP (Model Context Protocol) servers with FastMCP in Python. FastMCP is a framework for creating servers that expose tools, resources, and prompts to LLMs like Claude. The skill covers server creation, tool/resource definitions, storage backends (memory/disk/Redis/DynamoDB), server lifespans, middleware system (8 built-in types), server composition (import/mount), OAuth Proxy, authentication patterns, icons, OpenAPI integration, client configuration, cloud deployment (FastMCP Cloud), error handling, and production patterns. It prevents 25+ common errors including storage misconfiguration, lifespan issues, middleware order errors, circular imports, module-level server issues, async/await confusion, OAuth security vulnerabilities, and cloud deployment failures. Includes templates for basic servers, storage backends, middleware, server composition, OAuth proxy, API integrations, testing, and self-contained production architectures.Keywords: FastMCP, MCP server Python, Model Context
