Install target

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 majesticlabs-dev/majestic-marketplace at 04e97708c2.

    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 allows AI agents to write and execute tests for React components. It can generate unit tests, integration tests, and end-to-end tests using popular testing frameworks like Jest and React Testing Library. The agent can also analyze existing test suites and suggest improvements or identify potential bugs.

When to use it

  • Automated Regression Testing: Ensure new code changes don't break existing functionality by automatically running a suite of tests.
  • Component Development: Quickly verify the behavior of individual React components during development.
  • Code Refactoring: Gain confidence when refactoring code by ensuring that tests continue to pass after the changes.
  • Bug Fixing: Reproduce and isolate bugs by writing targeted tests that specifically check for failing scenarios.

Key capabilities

  • Unit testing with Jest
  • Integration testing with React Testing Library
  • Test generation from component source code
  • Analysis of existing test suites

Example prompts

  • "Write a unit test for the Button component."
  • "Generate an integration test to verify that the Login form submits data correctly."
  • “Analyze this test suite and suggest improvements.”

Tips & gotchas

This skill requires a working React development environment with Node.js and npm installed. The agent's effectiveness depends on clear and concise component code; poorly written components may result in less accurate or useful tests.
