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 derhaken/superantigravity at 2078b2c3d9.

    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 derhaken, focuses on performance optimization. It allows AI agents to improve the speed and efficiency of web applications. Specifically, it helps identify bottlenecks and implement strategies for faster loading times and a smoother user experience. The skill is part of the superantigravity project.

When to use it

  • Slow website load times: Use this when users are complaining about slow page loads or responsiveness issues.
  • Large JavaScript bundles: Optimize applications with substantial JavaScript code that's impacting performance.
  • Complex web applications: Apply optimization techniques to intricate single-page applications (SPAs) or those with many components.
  • Mobile devices: Improve the experience for users accessing your application on mobile networks and devices.

Key capabilities

  • Performance analysis
  • JavaScript bundling optimization
  • Code splitting
  • Lazy loading implementation

Example prompts

  • "Analyze this website's performance and suggest improvements."
  • "Optimize the JavaScript bundle size for my React application."
  • "Implement lazy loading for images on this page."
  • “Can you identify any bottlenecks in this code?”

Tips & gotchas

This skill likely requires some familiarity with web development concepts and tools. While it automates many optimization tasks, understanding the underlying principles will help interpret results and fine-tune adjustments.
