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 rohitg00/awesome-claude-code-toolkit at ebdf1d596d.

    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. It analyzes code and suggests improvements to reduce load times, enhance responsiveness, and improve the overall user experience of web applications. The skill focuses on identifying bottlenecks and providing actionable recommendations for optimization.

When to use it

  • Slow page loads: When users complain about slow loading times or sluggish interactions.
  • High bounce rates: To investigate if performance issues are contributing to a high percentage of visitors leaving your site quickly.
  • Poor mobile experience: To ensure your frontend performs well on devices with limited resources and slower network connections.
  • Large JavaScript bundles: When dealing with significant amounts of JavaScript code that impact initial load times.

Key capabilities

  • Code analysis for performance bottlenecks
  • Suggestion of optimization techniques
  • Identification of areas for improvement in frontend code

Example prompts

  • "Analyze this React component and suggest ways to improve its rendering performance."
  • "What are the biggest performance issues with this JavaScript bundle?"
  • "How can I reduce the size of my CSS file?"

Tips & gotchas

This skill assumes you have access to the frontend codebase. The recommendations provided should be reviewed carefully and tested thoroughly before implementation, as some optimizations may introduce unexpected side effects.
