Install target

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 curiositech/some_claude_skills at 6713fc7a64.

    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 analyzes React applications to identify and suggest performance optimizations. It can pinpoint bottlenecks in rendering, memory usage, and bundle size. The tool provides actionable recommendations for improving the overall speed and efficiency of a React application.

When to use it

  • Slow loading times: When users report that your React app takes too long to load or respond.
  • Performance regressions: After making changes to your codebase, you want to ensure performance hasn't degraded.
  • Large bundle sizes: You need to reduce the size of your JavaScript bundles for faster downloads and improved user experience.
  • Complex components: When dealing with intricate React components that might be causing rendering issues.

Key capabilities

  • Performance bottleneck identification
  • Rendering optimization suggestions
  • Memory usage analysis
  • Bundle size reduction recommendations

Example prompts

  • "Analyze this React application and suggest performance improvements."
  • "Identify memory leaks in my React component tree."
  • "What's causing slow rendering on this page?"
  • “Suggest ways to reduce the bundle size of this react app.”

Tips & gotchas

The skill requires access to the source code or a deployed version of the React application. The more context provided about the specific performance concerns, the better the recommendations will be.
