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 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 enables AI agents to generate secure frontend code, specifically focusing on protecting client-side applications from common vulnerabilities. It assists in building robust user interfaces that adhere to security best practices during the development lifecycle.

When to use it

  • Vulnerability Mitigation: When reviewing or generating code for potential XSS (Cross-Site Scripting) injection risks.
  • Secure Input Handling: During the implementation of forms and input fields to ensure data sanitization.
  • Dependency Auditing: When integrating third-party libraries that require security checks before deployment.
  • Policy Compliance: For projects requiring adherence to specific security standards like OWASP Top 10 guidelines.

Key capabilities

  • Generates secure HTML, CSS, and JavaScript code blocks.
  • Implements input validation and sanitization techniques.
  • Identifies and flags potential security flaws in frontend logic.
  • Provides code snippets that prevent common client-side attacks.

Example prompts

  • "Generate a React component for a login form that safely handles user input to prevent XSS attacks."
  • "Audit this JavaScript snippet for security vulnerabilities and suggest secure alternatives."
  • "Create a secure contact form using vanilla JavaScript with proper event handling and validation."

Tips & gotchas

Ensure the AI agent has access to up-to-date security libraries, as frontend threats evolve rapidly. Always manually review generated code in production environments, as automated tools may miss context-specific edge cases.
