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/crush-mcp-server at bb8eed14fe.

    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 provides automated testing for React components using Jest. It allows you to write and execute tests that verify the behavior of your UI elements, ensuring they render correctly and respond as expected to user interactions or data changes. The skill simplifies setting up a testing environment and running tests efficiently within an AI agent workflow.

When to use it

  • Automated Regression Testing: Run existing test suites after code changes to quickly identify any breaking modifications.
  • Component Development: Test individual React components in isolation as you build them, ensuring each piece functions correctly before integration.
  • Continuous Integration/Continuous Delivery (CI/CD): Integrate tests into your CI/CD pipeline for automated validation of code quality and stability.
  • Debugging UI Issues: Isolate and reproduce UI bugs by running targeted tests that focus on specific components or interactions.

Key capabilities

  • Jest testing framework integration
  • React component testing support
  • Automated test execution
  • Simplified setup for testing environment

Example prompts

  • "Run the Jest tests in the src/components directory."
  • "Execute all React component tests and report any failures."
  • “Test the rendering of the LoginButton.jsx component.”

Tips & gotchas

  • Requires a project with existing Jest and React testing configurations to function correctly.
  • Ensure your test environment is properly set up before using this skill within an AI agent workflow.
