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 miles990/claude-software-skills at 73632f218e.

    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 frontend performance. It identifies and suggests improvements for slow loading times, inefficient code, and other bottlenecks impacting user experience. The skill aims to reduce page load durations and improve overall application responsiveness through targeted optimizations.

When to use it

  • Slow website or application: When users report sluggishness or long loading times on a frontend application.
  • High bounce rate: If your analytics show a significant number of visitors leaving before interacting with the site.
  • Poor Core Web Vitals scores: To address issues identified by performance monitoring tools like Google PageSpeed Insights.
  • Large and complex applications: When dealing with substantial codebases or intricate UI components that may be contributing to performance degradation.

Key capabilities

  • Frontend performance analysis
  • Identification of bottlenecks
  • Suggestion of optimization strategies

Example prompts

  • "Analyze the frontend performance of [website URL] and suggest improvements."
  • "Identify any slow-loading components on this page: [page content]."
  • "What are some common causes of poor Core Web Vitals scores?"

Tips & gotchas

This skill requires access to the frontend code or a live website URL for analysis. The suggestions provided may require technical expertise to implement effectively, and might necessitate changes to existing codebase.
