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 duck4nh/antigravity-kit at 90de2acb0b.

    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 provides expert-level assistance with Docker, including creating and managing containers, building images, and troubleshooting common issues. It can generate Dockerfiles based on requirements, debug existing container configurations, and explain complex Docker concepts in a clear manner. The agent leverages its knowledge to automate tasks related to containerization.

When to use it

  • You need help writing a Dockerfile for an application.
  • You are experiencing issues with your Docker containers not starting or behaving as expected.
  • You want to understand the best practices for optimizing Docker image size and performance.
  • You're migrating an existing application to Docker and require guidance on containerizing it.

Key capabilities

  • Dockerfile generation
  • Container debugging
  • Image optimization advice
  • Explanation of Docker concepts

Example prompts

  • "Create a Dockerfile for a Python Flask application that uses requirements.txt."
  • "My Docker container is failing to start with an error 'permission denied'. Can you help me troubleshoot?"
  • "How can I reduce the size of my Node.js Docker image?"

Tips & gotchas

The skill assumes basic familiarity with Docker terminology and concepts. Providing specific details about your environment (e.g., operating system, application dependencies) will improve the quality of its responses.
