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 congdon1207/agents.md at 9f1aa55395.

    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 helps optimize frontend performance, likely through techniques like code splitting, lazy loading of assets, and minimizing render blocking resources. It aims to improve page load times and overall user experience by reducing the amount of work required for a browser to display a webpage. The specific implementation details are not provided in the source content.

When to use it

  • When users report slow page load times or responsiveness issues on your website.
  • During performance audits to identify bottlenecks and areas for improvement.
  • Before launching new features or redesigns, to ensure they don't negatively impact performance.
  • As part of a continuous integration/continuous deployment (CI/CD) pipeline to automatically optimize assets.

Key capabilities

  • Frontend performance optimization
  • Asset lazy loading
  • Code splitting
  • Minimizing render-blocking resources

Example prompts

  • "Optimize the frontend for faster page load times."
  • "Implement code splitting for this application."
  • "Lazy load images on this page to improve initial rendering speed."

Tips & gotchas

The source content does not provide any specific prerequisites or limitations. Consider that effective performance optimization often requires a deep understanding of frontend development principles and build tools.
