Golang CLI application development

golang-cli is an agent skill from the samber cc-skills-golang collection for building, extending and reviewing Go command-line tools. Its persona is a Go CLI engineer who builds tools that feel native to the Unix shell: composable, scriptable and predictable under automation. The skill has three modes. Build mode covers creating a new CLI from scratch, following its guidance on project structure, root command setup, flag binding and embedding the version. Extend mode adds subcommands, flags or shell completions to an existing tool, and asks the agent to read the current command tree first so changes match the existing structure. Review mode audits a CLI for correctness, checking a table of common mistakes, confirming that SilenceUsage and SilenceErrors are set appropriately, that flags are bound to configuration correctly, that exit codes are meaningful, and that standard output and standard error are kept separate. The skill recommends Cobra for commands and subcommands with Viper for configuration from files, environment variables and flags, the same stack used by well-known tools such as kubectl, Docker, gh and Hugo. For trivial single-purpose tools with few flags and no subcommands, it says the standard library flag package is enough. It refers to library documentation for current signatures. It is useful for developers who want a Go command-line tool that behaves well in scripts. It is listed on skills.sh, where the page shows install counts and GitHub stars for the collection, and its security audits all pass.
