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 karchtho/my-claude-marketplace at c7335a5662.

    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.

It enables users to understand the core concepts of containers, including image creation, running containers, and basic networking. The skill aims to equip users with enough understanding to begin working with Docker in a development or deployment environment.

When to use it

  • You're new to Docker and want to learn the fundamental concepts.
  • You need help creating your first simple Docker container.
  • You’re troubleshooting issues related to running containers locally.
  • You are preparing for more advanced Docker topics like orchestration or multi-container applications.

Key capabilities

  • Container fundamentals explanation
  • Image creation guidance
  • Running container instructions
  • Basic networking concepts

Example prompts

  • "Explain how a Docker image differs from a Docker container."
  • "Can you show me an example of running a simple 'hello world' container?"
  • "What are the basic steps to create a Dockerfile?"

Tips & gotchas

This skill assumes no prior knowledge of Docker. While it covers basics, further learning is recommended for more complex use cases and advanced features.
