Golang Cli Cobra Viper

If you're building a Go CLI that's more than a throwaway script, you probably want Cobra and Viper. This skill knows the standard patterns for wiring them together: command structure, flag binding, config file precedence, the whole setup. It's the same stack that powers kubectl, Docker CLI, and GitHub's gh, so you're not learning some niche approach. Useful when you need subcommands, multiple config sources, or shell completions without writing that plumbing yourself. The integration between Cobra's flags and Viper's config management is where most people fumble, and that's exactly what this handles.

Overview

Cobra and Viper are the industry-standard libraries for building production-quality CLIs in Go. Cobra provides command structure and argument parsing, while Viper manages configuration from multiple sources with clear precedence rules.

Key Features:

🎯 Cobra Commands: POSIX-compliant CLI with subcommands (app verb noun --flag)
⚙️ Viper Config: Unified configuration from flags, env vars, and config files
🔄 Integration: Seamless Cobra + Viper plumbing patterns
🐚 Shell Completion: Auto-generated completions for bash, zsh, fish, PowerShell
✅ Production Ready: Battle-tested by kubectl, docker, gh, hugo
