Command Development

Official
anthropics·vlatest·backend·Apache-2.0

This skill allows you to generate complex commands for AI agents, streamlining workflows and automating tasks efficiently.

Repository

Install on your platform

Showing Claude Code. One command installs this skill into any of the agents below.

  1. 1

    Run this in your project

    terminal
    $ npx skills add anthropics/claude-plugins-official --skill command-development -a claude-code

  2. Uses the open-source skills CLI and needs Node.js. Add -g to install it for your user instead of this project.

Install target

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 anthropics/claude-plugins-official at 921c90ff92.

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

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

The skill enables AI agents to develop and execute custom commands, allowing for tailored interactions with external systems or tools. It supports the creation of command-line interfaces (CLIs) and integration with APIs, enabling automation and enhanced functionality.

When to use it

  • To automate repetitive tasks through scriptable commands
  • When integrating an AI agent with third-party tools or services via API calls
  • For building custom workflows that require precise control over system operations

Key capabilities

  • Creation of custom CLI commands
  • Integration with external APIs
  • Execution of system-level operations

Example prompts

  • "Create a command to fetch weather data from an API."
  • "Generate a script that backs up files to the cloud."
  • "Develop a CLI tool for managing user accounts in a database."

Tips & gotchas

  • Ensure proper permissions are granted for any system-level commands or API integrations.
  • Test custom commands thoroughly before deployment to avoid unintended behavior.
