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 rdimascio/react-marketplace at 2566073cf7.

    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

The rdimascio-performance-analyzer skill analyzes the performance of React components. It identifies bottlenecks and areas for optimization within a React application, providing insights into rendering times and potential issues impacting user experience. The tool can pinpoint specific component inefficiencies and suggest improvements to enhance overall application speed.

When to use it

  • Debugging slow UI: Use when users report sluggishness or delays in your React application's interface.
  • Optimizing complex components: Employ this skill when dealing with intricate components that might be contributing to performance problems.
  • Identifying rendering bottlenecks: Leverage the analyzer to pinpoint which components are taking the longest to render and require attention.
  • Proactive optimization: Integrate into your development workflow for regular performance checks and preventative maintenance.

Key capabilities

  • React component profiling
  • Rendering time analysis
  • Bottleneck identification
  • Performance improvement suggestions

Example prompts

  • "Analyze the rendering performance of my ProductList component."
  • "Identify any bottlenecks in the UI update process for this React application."
  • "Show me a report detailing the slowest components and their rendering times."

Tips & gotchas

The skill requires access to the React codebase being analyzed. Ensure proper environment setup and dependencies are met before running performance analysis.
