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 pluginagentmarketplace/custom-plugin-react at fc1da8328b.

    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, pluginagentmarketplace-react-performance, analyzes React component performance and provides actionable insights. It identifies bottlenecks in rendering, updates, and overall application responsiveness. The tool aims to improve the user experience by optimizing React applications for speed and efficiency.

When to use it

  • Slow UI Updates: When users report sluggishness or delays when interacting with a React-based interface.
  • Performance Regression: After code changes, to ensure new features haven't negatively impacted existing performance.
  • Complex Components: When dealing with components that have many child elements or complex logic, potentially leading to rendering issues.
  • Mobile Optimization: To identify areas for improvement when targeting mobile devices with limited resources.

Key capabilities

  • React component profiling
  • Rendering bottleneck identification
  • Update performance analysis
  • Actionable optimization suggestions

Example prompts

  • "Analyze the performance of my ProductList React component."
  • "Identify any rendering bottlenecks in the user profile page."
  • "Give me recommendations for optimizing update frequency on the dashboard."

Tips & gotchas

This skill requires a working React application to analyze. The accuracy of the analysis depends on the quality and completeness of the code provided or accessible to the AI agent.
