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 failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No pipe-to-shell installers: failed

    Runs code fetched at install time in 1 place.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

    What it found

    • skills/docker-best-practices/SKILL.md:314remote script piped into a shell
      curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/main/contrib/install.sh | sh

  • 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

    Only contacts known or declared hosts: raw.githubusercontent.com.

    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.

    Hosts contacted

    raw.githubusercontent.comsource host

  • 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.

  • Pinned to a commit: passed

    Scanned hieutrtr/ai1-skills at d8244c1acd.

    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 guidance and recommendations for implementing Docker best practices. It can help users optimize container images, improve security, and ensure consistent deployments across different environments. The skill focuses on creating efficient and maintainable Docker workflows.

When to use it

  • You're building a new application and want to define a robust Dockerfile from the start.
  • Your existing Docker containers are slow or inefficient, and you need help optimizing them.
  • You’re experiencing inconsistencies between development, staging, and production environments using Docker.
  • You want to improve the security posture of your containerized applications.

Key capabilities

  • Dockerfile optimization suggestions
  • Security best practices for Docker images
  • Strategies for efficient image layering
  • Guidance on multi-stage builds

Example prompts

  • "Review this Dockerfile and suggest improvements."
  • "What are some common security vulnerabilities in Docker containers, and how can I prevent them?"
  • "How can I reduce the size of my Docker image?"
  • “Explain best practices for using multi-stage builds.”

Tips & gotchas

This skill assumes a basic understanding of Docker concepts. For optimal results, provide clear and concise Dockerfile content or descriptions of your current setup.
