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 dokhacgiakhoa/antigravity-ide at c4a059bbf7.

    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 optimizes application performance. It helps identify and resolve bottlenecks, leading to faster load times and a more responsive user experience. The tool focuses on frontend applications, specifically targeting areas for improvement in rendering speed and resource utilization.

When to use it

  • Analyzing slow-loading web pages to pinpoint the root cause of delays.
  • Troubleshooting performance issues in complex single-page applications (SPAs).
  • Identifying opportunities to reduce JavaScript bundle sizes and improve initial load times.
  • Optimizing rendering performance on mobile devices with limited resources.

Key capabilities

  • Performance bottleneck identification
  • Frontend application optimization
  • Rendering speed improvement
  • Resource utilization reduction

Example prompts

  • "Analyze the performance of this webpage: [URL]"
  • "Identify bottlenecks in my SPA's rendering process."
  • "Suggest ways to reduce the size of my JavaScript bundle."

Tips & gotchas

This skill is most effective when applied to frontend applications. It may require some understanding of web development concepts like bundling, lazy loading, and code splitting to fully interpret its recommendations.
