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

    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.

  • 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 ancoleman/ai-design-components at 76551b7b19.

    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 automates server configuration changes to minimize vulnerabilities by applying industry best practices and threat intelligence. It focuses on proactive reduction of attack surfaces across various infrastructure layers, including operating systems, containers, cloud configurations, networks, and databases. The skill utilizes CIS Benchmarks and zero-trust principles to enforce security controls and least privilege access.

When to use it

  • Hardening production infrastructure before deployment.
  • Meeting compliance requirements such as SOC 2, PCI-DSS, HIPAA, or FedRAMP.
  • Implementing a zero-trust security architecture.
  • Reducing risks associated with container or cloud misconfigurations.
  • Preparing for security audits or penetration tests.

Key capabilities

  • Operating System Hardening (Linux): Kernel parameter tuning, SSH hardening, user/group management, file system permissions, service minimization, SELinux/AppArmor enforcement.
  • Container Hardening: Minimal base images, non-root execution, read-only filesystems, Seccomp/AppArmor profiles, resource limits, Pod Security Standards enforcement.
  • Cloud Configuration Hardening: IAM least privilege, MFA enforcement, network security group configuration, encryption at rest and in transit, CSPM integration.
  • Network Hardening: Default-deny policies, network segmentation, TLS/mTLS enforcement, DNS security (DNSSEC, filtering).
  • Database Hardening: Authentication hardening, connection encryption, audit logging enablement, role-based permissions.

Example prompts

  • "Harden the Linux operating system on this server."
  • "Apply CIS benchmark settings to our container deployment."
  • "Enforce least privilege IAM policies for cloud resources."
  • "Review and harden database network access controls."

Tips & gotchas

  • The skill applies configuration changes based on industry standards, so review the proposed modifications before implementation.
  • Ensure you have appropriate permissions to modify system configurations.
  • This skill focuses on configuration hardening; it does not replace other security measures like vulnerability scanning or intrusion detection systems.
