Golang CLI application development. Use when building, modifying, or reviewing a Go CLI tool — especially for command structure, flag handling, configuration layering, version embedding, exit codes, I/O patterns, signal handling, shell completion, argument validation, and CLI unit testing. Also triggers when code uses cobra, viper, or urfave/cli. For cobra-specific APIs → See \`samber/cc-skills-golang@golang-spf13-cobra\` skill; for viper configuration layering → See \`samber/cc-skills-golang@golang-spf13-viper\` skill.

## From README

Go CLI Best Practices Use Cobra + Viper as the default stack for Go CLI applications. Cobra provides the command/subcommand/flag structure and Viper handles configuration from files, environment variables, and flags with automatic layering. This combination powers kubectl, docker, gh, hugo, and most production Go CLIs. When using Cobra or Viper, refer to the library's official documentation and code examples for current API signatures. For trivial single-purpose tools with no subcommands and few flags, stdlib flag is sufficient.
