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 manutej/luxor-claude-marketplace at 1861cc9720.

    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 jest-react-testing skill enables AI agents to write and execute unit tests for React components using Jest. It supports testing component rendering, props validation, event handling, and integration with React hooks and state management libraries like Redux.

When to use it

  • You need to verify the correctness of a React component's behavior under different input conditions.
  • You want to automate test suites as part of a CI/CD pipeline for frontend applications.
  • Your project uses Jest as the testing framework, and you're looking to streamline test writing with AI assistance.
  • You are refactoring or debugging components and need quick feedback through automated tests.

Key capabilities

  • Writing snapshot tests for React component rendering
  • Mocking API calls and event handlers in tests
  • Validating props and state changes using Jest matchers
  • Integration with React hooks like useState and useEffect
  • Support for testing conditional rendering and error boundaries

Example prompts

  • "Write a Jest test to check if the button renders correctly when clicked."
  • "Mock an API call in this component's test suite and verify the response handling."
  • "Generate tests for all props of the UserCard React component."

Tips & gotchas

  • Ensure your project has Jest installed and configured before using this skill.
  • Some advanced testing scenarios (e.g., asynchronous rendering) may require additional setup or custom matchers.
