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.

About this skill

What it does

This skill allows an AI agent to perform Linux system hardening tasks. It can identify potential vulnerabilities based on current configurations and suggest remediation steps according to security best practices. The skill aims to improve the overall security posture of a Linux server or virtual machine by applying standard hardening techniques.

When to use it

  • Security Audits: When you need a quick assessment of a Linux system's security configuration.
  • New Server Deployment: To automatically harden newly provisioned servers before they enter production.
  • Compliance Checks: To ensure systems meet specific security compliance standards (e.g., CIS benchmarks).
  • Post-Incident Review: To identify and address vulnerabilities that might have been exploited during a security incident.

Key capabilities

  • Vulnerability identification based on configuration analysis
  • Remediation suggestions for identified vulnerabilities
  • Adherence to security best practices (implied)

Example prompts

  • "Assess the security of this server: [server IP address]"
  • "What are the potential vulnerabilities in my /etc/ssh/sshd_config file?"
  • "Harden this Ubuntu 22.04 system according to CIS benchmarks."

Tips & gotchas

The skill's effectiveness depends on accurate access and configuration information being provided. It is not a replacement for comprehensive security expertise, but rather a tool to assist in the hardening process.
