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 personamanagmentlayer/pcl at 79ccaa9820.

    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 enables AI agents to act as Docker experts, providing guidance and automating tasks related to containerization. It covers a wide range of topics including building optimized Dockerfiles with multi-stage builds, managing container lifecycles, configuring Docker Compose for multi-container applications, and implementing best practices for security and networking within Docker environments. The skill provides expertise on image layering, caching strategies, and choosing appropriate base images to streamline development workflows.

When to use it

  • When you need help optimizing a Dockerfile to reduce image size or build time.
  • To design and configure multi-container applications using Docker Compose.
  • For guidance on implementing container security best practices like user namespaces and secrets management.
  • When troubleshooting issues related to Docker networking, volumes, or service dependencies.
  • To understand strategies for managing images in public (Docker Hub) or private registries.

Key capabilities

  • Dockerfile Optimization: Creating multi-stage builds, optimizing layers, selecting appropriate base images (Alpine, Distroless, scratch), and using build arguments.
  • Container Management: Lifecycle management, resource limits, health checks, and signal handling for graceful shutdown.
  • Docker Compose Orchestration: Defining services, managing dependencies, configuring networking, utilizing volumes for persistent data, and defining environment variables.
  • Image Registry Expertise: Working with Docker Hub and private registries, including image tagging strategies.
  • Container Security: Implementing user namespaces, capabilities, and secrets management.

Example prompts

  • "Can you help me optimize this Dockerfile to reduce its size?" (followed by the Dockerfile content)
  • "I'm setting up a multi-container application with Docker Compose. How do I define service dependencies?"
  • "What are some best practices for securing my Docker containers?"

Tips & gotchas

  • The skill requires providing specific details or code snippets (like Dockerfiles) to receive targeted advice.
  • The skill focuses on Docker containerization and related technologies; it does not cover broader cloud platform management.
  • To get the most out of the skill, be prepared to describe your current setup and desired outcomes clearly.
