Repository

Install on your platform

Showing Claude Code. One command installs this skill into any of the agents below.

  1. 1

    Run this in your project

    terminal
    $ npx skills add snakeo/claude-debug-and-refactor-skills-plugin --skill refactor:docker -a claude-code

  2. Uses the open-source skills CLI and needs Node.js. Add -g to install it for your user instead of this project.

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 snakeo/claude-debug-and-refactor-skills-plugin at e2e79df88e.

    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 refactors Dockerfiles to improve readability, efficiency, and security. It can analyze existing Dockerfiles, identify potential issues such as inefficient layer usage or unnecessary commands, and suggest improvements. The skill aims to produce cleaner, more maintainable Docker configurations.

When to use it

  • You have a complex Dockerfile that is difficult to understand or modify.
  • Your Docker image build times are slow and you suspect inefficiencies in the Dockerfile.
  • You want to ensure your Dockerfile follows best practices for security and maintainability.
  • You're migrating an existing application to containers and need help optimizing the Dockerfile.

Key capabilities

  • Dockerfile analysis
  • Inefficient layer identification
  • Unnecessary command detection
  • Security vulnerability suggestions (implied)
  • Improved readability through refactoring

Example prompts

  • "Refactor this Dockerfile: [paste Dockerfile content]"
  • "Analyze this Dockerfile and suggest improvements for build time optimization: [paste Dockerfile content]"
  • "Can you make this Dockerfile more secure? [paste Dockerfile content]"

Tips & gotchas

The skill's effectiveness depends on the complexity and quality of the input Dockerfile. It is best suited for Dockerfiles that already have some structure, as it refactors rather than creates from scratch.
