Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned bobmatnyc/claude-mpm-skills at 718070a7d6.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

The golang-cli-cobra-viper skill enables Go developers to rapidly build robust command-line interfaces (CLIs) using the Cobra framework for command parsing and Viper for flexible configuration management. It streamlines the creation of multi-command applications with automatic help generation, flag handling, and environment variable support.

When to use it

  • Building internal developer tools or DevOps utilities that require complex subcommand hierarchies.
  • Creating CLI applications that must adapt behavior based on config files (YAML, JSON), environment variables, or command-line flags.
  • Developing production-ready Go services where consistent help text and error handling are critical for user experience.
  • Prototyping new CLI features quickly without writing repetitive boilerplate code for argument parsing.

Key capabilities

  • Automatic generation of comprehensive help documentation for commands and subcommands.
  • Seamless integration of configuration from multiple sources: command-line flags, environment variables, config files, and default values.
  • Support for both short (-f) and long (--flag) flag syntax with automatic validation.
  • Built-in support for persistent global flags and context propagation across commands.

Example prompts

  • "Generate a Go CLI using Cobra with three subcommands: deploy, logs, and config, each accepting specific flags."
  • "Set up Viper to load configuration from a YAML file at runtime while allowing command-line flags to override settings."
  • "Create a multi-command application where the 'server' command accepts a port flag that defaults to 8080 but can be overridden via an environment variable."

Tips & gotchas

Ensure your Go module includes both github.com/spf13/cobra and github.com/spf13/viper dependencies before initializing commands. Be mindful that Viper merges configuration sources in a specific order; command-line flags always take precedence over config files, so test edge cases where users provide conflicting inputs.
