golang-spf13-cobra
Golang CLI command tree library using spf13/cobra — cobra.Command, RunE vs Run, PersistentPreRunE hook chain, Args validators (NoArgs, ExactArgs, MatchAll, custom), persistent vs local flags, command groups, ValidArgsFunction, RegisterFlagCompletionFunc, ShellCompDirective, usage/help template customization, man-page and markdown doc generation, and testing with SetArgs/SetOut/SetErr. Apply when using or adopting spf13/cobra, or when the codebase imports github.com/spf13/cobra. For configuration layering alongside cobra, see the samber/cc-skills-golang@golang-spf13-viper skill. For general CLI architecture (project layout, exit codes, signal handling, I/O patterns), see samber/cc-skills-golang@golang-cli.
