Skill UI

This skill guides the development of robust, Unix-like Command Line Interfaces (CLIs) in Go using the industry-standard `cobra` library. It covers the entire lifecycle of a CLI application, including command tree setup, managing persistent vs. local flags, advanced positional argument validation, and utilizing the full execution hook chain (RunE). Ideal for engineers adopting or maintaining sophisticated Go CLI projects.

A comprehensive guide to using the spf13/viper library in Go for robust, layered configuration management. This skill details how to handle configuration precedence from multiple sources—including command flags, environment variables, config files (JSON, YAML, TOML), and remote KV stores. Learn advanced techniques like source binding, structured unmarshaling with mapstructure, and hot reloading for building reliable Go applications.

A comprehensive guide and toolset for generating OpenAPI/Swagger documentation for Go APIs. By using annotations (@Summary, @Param, @Success, etc.), developers can treat documentation as a formal contract. Supports multiple popular Go frameworks (Gin, Echo, Fiber, net/http), defines complex security schemes (JWT, OAuth2), and guides the entire lifecycle from setup to auditing.
