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 armanzeroeight/fastagent-plugins at 61b61a99e6.

    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

The armanzeroeight-performance-optimizer skill analyzes and suggests improvements to frontend code for better performance. It identifies potential bottlenecks, such as inefficient JavaScript or large image sizes, and provides actionable recommendations. This helps developers optimize their web applications for faster loading times and a smoother user experience.

When to use it

  • Slow website load times: Use the skill when users are reporting slow page loads or you've identified performance issues in your analytics.
  • Large JavaScript bundles: If your application has large JavaScript files, this skill can help identify opportunities for code splitting and optimization.
  • Unoptimized images: The skill is useful for identifying and suggesting optimizations to image sizes and formats.
  • Before a major release: Incorporate performance analysis as part of your pre-release process to ensure a smooth user experience.

Key capabilities

  • JavaScript bundle size analysis
  • Image optimization suggestions
  • Performance bottleneck identification
  • Actionable recommendations for improvement

Example prompts

  • "Analyze the frontend code for my website and suggest performance improvements."
  • "Identify any large JavaScript bundles in my application."
  • "Find unoptimized images on this page: [URL]"

Tips & gotchas

The skill's effectiveness depends on providing accurate URLs or code snippets for analysis. It’s best used by developers familiar with frontend performance optimization techniques to interpret and implement the recommendations provided.
