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 rmyndharis/antigravity-skills at 3eff4af253.

    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 automatically generates secure frontend code, specifically focusing on preventing common vulnerabilities like XSS and injection attacks. It analyzes existing JavaScript or HTML snippets and suggests improvements to enhance security posture. The generated code adheres to best practices for secure coding in a modern web development context.

When to use it

  • Code Review: Quickly assess the security of existing frontend codebases and identify potential vulnerabilities.
  • New Feature Development: Generate secure JavaScript or HTML components from scratch, reducing the risk of introducing new vulnerabilities.
  • Security Audits: Automate parts of a security audit process by identifying common frontend security flaws.
  • Training/Education: Demonstrate secure coding practices and provide examples for developers learning about frontend security.

Key capabilities

  • XSS prevention
  • Injection attack mitigation
  • Secure code generation
  • Code analysis & suggestions
  • Modern web development best practices adherence

Example prompts

  • "Analyze this JavaScript code snippet for potential XSS vulnerabilities: [code]"
  • "Generate a secure HTML form input field that prevents injection attacks."
  • "Review this React component and suggest improvements to enhance its security."

Tips & gotchas

The skill's effectiveness depends on the clarity and completeness of the provided code. It is most effective when given well-structured, modular code snippets rather than large, monolithic files.
