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 blogic-cz/blogic-marketplace at aaa7762eb5.

    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 blogic-cz, focuses on performance optimization for frontend applications. It aims to improve website loading times and overall responsiveness through various techniques. The skill is designed to identify bottlenecks and suggest targeted improvements without requiring extensive manual intervention.

When to use it

  • Slow Website Loading: When users report slow page load speeds or a sluggish user experience.
  • High Bounce Rate: If your website has a high bounce rate, indicating visitors leave quickly due to poor performance.
  • Poor Core Web Vitals: To improve scores on metrics like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).
  • Mobile Optimization: When optimizing a site for mobile devices with limited bandwidth and processing power.

Key capabilities

  • Frontend performance optimization
  • Bottleneck identification
  • Targeted improvement suggestions

Example prompts

  • "Analyze this website [URL] and identify areas for performance improvement."
  • "Suggest optimizations to reduce the Largest Contentful Paint (LCP) on [URL]."
  • "What are the biggest performance bottlenecks affecting mobile users of [URL]?"

Tips & gotchas

This skill is most effective when provided with a specific URL to analyze. While it provides suggestions, implementing them may require technical expertise and adjustments based on your specific frontend architecture.
