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 mindrally/skills at 7682ca7771.

    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

Performance Optimization

What it does

This skill enables AI agents to analyze and improve the runtime efficiency of frontend applications. It focuses on reducing load times, minimizing resource consumption, and enhancing overall user experience through targeted technical adjustments.

When to use it

  • Diagnosing slow page loads or high Time to Interactive (TTI) metrics in production environments.
  • Reducing bundle sizes by identifying unused code, assets, or inefficient dependencies.
  • Optimizing rendering performance for complex dashboards or data-heavy single-page applications.
  • Preparing an application for mobile deployment where bandwidth and processing power are limited.

Key capabilities

  • Automated analysis of frontend performance bottlenecks.
  • Identification of render-blocking resources and critical path delays.
  • Recommendations for code splitting, lazy loading, and asset optimization.
  • Monitoring of core web vitals to ensure compliance with modern standards.

Example prompts

  • "Analyze my current React application's load time and suggest specific changes to improve the First Contentful Paint."
  • "Identify large JavaScript bundles in my codebase that can be split or deferred to speed up initial rendering."
  • "Optimize the image assets in this frontend project to reduce total page weight without losing visual quality."

Tips & gotchas

Performance optimization is highly dependent on the specific technology stack and architecture of your application. Ensure you have access to the relevant source code and build configurations before running deep analysis, as some tools may not be able to inspect minified or obfuscated production builds effectively.
