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 omer-metin/skills-for-antigravity at e8dcf4e873.

    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, authored by Omer Metin, provides security hardening recommendations for systems. It can analyze a system description and suggest specific actions to improve its resilience against common vulnerabilities. The skill aims to reduce attack surface area and enhance overall security posture through practical configuration changes and best practices.

When to use it

  • New System Deployment: Before launching a new server or application, use this skill to proactively identify and mitigate potential security risks.
  • Security Audit Preparation: Generate a preliminary list of hardening recommendations ahead of a formal security audit.
  • Vulnerability Remediation: Get suggestions for addressing specific vulnerabilities identified in a system scan.
  • Compliance Requirements: Assist in meeting industry-specific security compliance standards (e.g., CIS benchmarks).

Key capabilities

  • Security Hardening Recommendations
  • Vulnerability Mitigation Suggestions
  • Attack Surface Reduction
  • System Configuration Analysis

Example prompts

  • "Analyze this server configuration and suggest hardening steps: [server configuration details]"
  • "What are the most critical security improvements I can make to a Linux web server?"
  • "How can I reduce the attack surface of my Kubernetes cluster?"

Tips & gotchas

The skill's effectiveness depends on providing detailed information about the system being analyzed. Vague descriptions will result in less specific or useful recommendations.
