This skill enables users to create custom plugins for this AI, expanding its functionality and tailoring it to specific needs.

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 abcfed/claude-marketplace --skill plugin-authoring -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

    Only contacts known or declared hosts: github.com.

    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.

    Hosts contacted

    github.comsource host

  • 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 abcfed/claude-marketplace at f90c972905.

    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

This skill allows you to author plugins. It provides tools and guidance for creating custom functionality that can be integrated into AI agents. The skill streamlines the development process, enabling users to extend agent capabilities with tailored solutions.

When to use it

  • You want to create a new tool or feature for an AI agent beyond its existing capabilities.
  • You need to automate a specific task within an AI agent's workflow.
  • You are developing a custom integration between an AI agent and another application.
  • You wish to build specialized functionality tailored to a particular domain or use case.

Key capabilities

  • Plugin creation tools
  • Guidance for plugin development
  • Streamlined development process
  • Extending agent capabilities

Example prompts

  • "Help me create a plugin that can summarize legal documents."
  • "I want to build a plugin that integrates with my CRM. Can you guide me through the steps?"
  • “Show me how to author a plugin for data extraction.”

Tips & gotchas

This skill requires some familiarity with software development concepts and potentially the specific AI agent platform you intend to target. The complexity of the resulting plugin will depend on the desired functionality.
