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 failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • Declares what it does: failed

    No SKILL.md was found in the skill's directory.

    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 sickn33/antigravity-awesome-skills at 5a4cdd9df8.

    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 provides recommendations and guidance for writing secure, reliable, and maintainable AWS CloudFormation templates. It helps users identify common pitfalls, suggests best practices for structuring templates, and offers advice on resource configuration to improve overall infrastructure as code quality. The skill aims to reduce errors and promote consistency in CloudFormation deployments.

When to use it

  • You're creating a new CloudFormation template from scratch and want to ensure you follow industry best practices.
  • You have an existing CloudFormation template that needs refactoring or optimization for security and maintainability.
  • You’re troubleshooting deployment issues in your CloudFormation templates and need help identifying potential causes.
  • You're seeking advice on how to improve the structure and organization of a complex CloudFormation stack.

Key capabilities

  • Provides recommendations for secure resource configuration.
  • Suggests best practices for template structuring and organization.
  • Identifies common CloudFormation pitfalls and errors.
  • Offers guidance on improving overall infrastructure as code quality.

Example prompts

  • "Review this CloudFormation template and suggest improvements for security." (Provide the template content)
  • "What are some best practices for organizing a large CloudFormation stack?"
  • “How can I prevent common errors when deploying CloudFormation?”

Tips & gotchas

  • The skill's effectiveness depends on providing clear and complete CloudFormation template code or descriptions.
  • While the skill offers valuable guidance, it’s not a substitute for thorough testing and understanding of AWS services.
