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 johnkmcleod9/antigravity-skills-workflows at d3a39016b3.

    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 assistance with Docker, enabling you to build, manage, and troubleshoot containerized applications. It can generate Dockerfiles, debug existing configurations, and explain complex concepts related to containers and orchestration. The agent leverages its knowledge to automate common Docker tasks and improve your workflow efficiency.

When to use it

  • You need help writing a Dockerfile for an application.
  • You're encountering issues with container networking or port mappings.
  • You want to understand the best practices for optimizing Docker image size.
  • You’re struggling to debug a failing container and require expert analysis of logs and configurations.

Key capabilities

  • Dockerfile generation
  • Container debugging
  • Docker configuration optimization
  • Explanation of Docker concepts

Example prompts

  • "Generate a Dockerfile for a Python Flask application with requirements from requirements.txt."
  • "My container is failing to start; can you analyze the logs and suggest solutions?"
  • "How can I reduce the size of my Node.js Docker image?"

Tips & gotchas

The skill assumes basic familiarity with command-line interfaces and software development workflows. Providing specific context, such as application code or error messages, will significantly improve the quality of its responses.
