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 bagelhole/devops-security-agent-skills at 0365f57a07.

    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 helps to secure containerized applications. It performs automated checks against common security misconfigurations and provides remediation advice, reducing the attack surface of containers. The skill aims to improve overall container security posture through proactive vulnerability identification and mitigation.

When to use it

  • Before deploying a new container: Ensure your containers are hardened before they enter production.
  • During routine security audits: Regularly assess existing container deployments for vulnerabilities.
  • Responding to security alerts: Investigate potential security issues related to container environments.
  • Automating security compliance checks: Verify adherence to established container security best practices.

Key capabilities

  • Automated security checks
  • Vulnerability identification
  • Remediation advice
  • Container hardening

Example prompts

  • "Harden this Dockerfile."
  • "Check the security configuration of my Kubernetes deployment."
  • "What are the common vulnerabilities in container images?"

Tips & gotchas

The skill's effectiveness relies on accurate and complete container configurations. Review remediation advice carefully, as some changes may impact application functionality.
