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 playground skill provides an interactive environment for testing and experimenting with AI agent capabilities. It allows users to run code snippets, test plugins, and explore different functionalities in a safe and controlled setting.

When to use it

  • Testing new plugins or features before deploying them in production
  • Debugging and troubleshooting AI agent behavior
  • Experimenting with different prompts and inputs to understand how the agent responds

Key capabilities

  • Interactive code execution
  • Plugin testing environment
  • Real-time feedback and results visualization

Example prompts

  • "Run this Python script in the playground: print('Hello, world!')"
  • "Test the image generation plugin with this prompt: 'A futuristic cityscape at sunset'"
  • "Simulate a conversation between two AI agents using the dialogue plugin"

Tips & gotchas

  • Ensure that any code or plugins used are compatible with the playground environment.
  • Be mindful of resource limits and avoid running long-running processes that could affect performance.
