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 kentoshimizu/sw-agent-skills at 5b7bafb626.

    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 foundational knowledge and practical application of Docker. It enables users to understand containerization principles, build simple Docker images, and run containers based on those images. The skill aims to demystify Docker's core concepts and provide a starting point for more advanced usage.

When to use it

  • Setting up a development environment: Quickly create isolated environments with specific dependencies for different projects.
  • Running applications consistently: Ensure your application behaves the same way across various platforms by packaging it in a Docker container.
  • Learning about containerization: Gain a basic understanding of Docker and its benefits for software deployment.
  • Reproducing complex setups: Easily recreate intricate server configurations using Docker images.

Key capabilities

  • Understanding Docker concepts (images, containers, volumes)
  • Building simple Docker images from Dockerfiles
  • Running Docker containers
  • Basic Docker commands (e.g., docker run, docker build)

Example prompts

  • "Explain how to create a Docker image for a Python application."
  • "Show me an example of running a container based on the official Ubuntu image."
  • “What is the difference between a Docker image and a Docker container?”

Tips & gotchas

  • A basic understanding of command-line interfaces is helpful.
  • This skill focuses on fundamentals; more advanced topics like networking or orchestration are not covered.
