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 vchirrav/owasp-secure-coding-md at a0f04031cb.

    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 performs container image scanning using Hadolint, a tool that analyzes Dockerfiles for common errors and anti-patterns. It identifies potential security vulnerabilities and inefficiencies in the Dockerfile based on best practices. The skill helps ensure images are built securely and efficiently by flagging issues related to caching, base image selection, and command usage.

When to use it

  • Dockerfile Review: Before deploying a containerized application, scan the Dockerfile to proactively identify and fix potential problems.
  • CI/CD Pipeline Integration: Integrate Hadolint scanning into your CI/CD pipeline to automatically check for issues during image builds.
  • Security Audits: As part of a broader security audit process, use this skill to assess the quality and security posture of container images.
  • Developer Training: Help developers learn best practices by providing feedback on their Dockerfile structure and content.

Key capabilities

  • Dockerfile analysis
  • Hadolint integration
  • Security vulnerability identification (through Dockerfile anti-patterns)
  • Efficiency improvement suggestions within Dockerfiles

Example prompts

  • "Scan this Dockerfile for Hadolint issues: [Dockerfile Content]"
  • "Analyze the following Dockerfile and report any potential security concerns: [Dockerfile Content]"
  • "Check this Dockerfile against best practices using Hadolint: [Dockerfile Content]"

Tips & gotchas

  • Requires a valid Dockerfile as input. The skill will not function without a properly formatted Dockerfile to analyze.
