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 duck4nh/antigravity-kit at 90de2acb0b.

    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, duck4nh-react-performance, provides tools and techniques to optimize React application performance. It focuses on identifying bottlenecks and implementing strategies like memoization, code splitting, and efficient rendering to improve load times and responsiveness. The skill aims to help developers diagnose and resolve common React performance issues.

When to use it

  • Slow initial load: When a React application takes too long to initially render.
  • Performance regressions: After making changes to the codebase, when you notice a slowdown in rendering or interactions.
  • Frequent re-renders: When components are unnecessarily re-rendering, leading to performance degradation.
  • Complex UIs: When dealing with large and complex user interfaces that require careful optimization.

Key capabilities

  • Performance profiling
  • Memoization techniques
  • Code splitting strategies
  • Efficient rendering optimizations

Example prompts

  • "Analyze the React component MyComponent for performance bottlenecks."
  • "Suggest ways to optimize re-renders in my application's dashboard view."
  • "Implement memoization on this function: [function code]"

Tips & gotchas

This skill requires a basic understanding of React concepts and development practices. It may be most effective when used alongside profiling tools for accurate diagnosis.
