What problem does it solve?

This Skill helps you design, implement, and test Go command-line applications without burying core logic inside framework code or tangled directory layouts. It reduces configuration drift, simplifies command routing, and makes CLI behavior easier to maintain.

Core Features & Use Cases

• Command-first architecture: Keep Cobra focused on flags, subcommands, and routing while your business logic stays independent and reusable.
• Unified configuration: Combine defaults, config files, environment variables, and flags through Viper with typed config structs.
• Reliable CLI testing: Exercise commands in memory for fast, deterministic tests without compiling or spawning binaries.
• Use case: Build a production Go CLI that reads configuration from env and YAML, exposes clean subcommands, and validates behavior with repeatable tests.

Quick Start

Ask the assistant to design or refactor your Go CLI using Cobra and Viper while keeping business logic decoupled, configuration typed, and tests in memory.
