samber/golang-cli
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.
