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 itechmeat/llm-code at 7ae8a00524.

    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 enables AI agents to execute React component tests using the Testing Library ecosystem. It provides a robust framework for verifying user interactions and rendering behavior in React applications without relying on implementation details like DOM queries or props.

When to use it

  • Validating that user clicks, input changes, and form submissions trigger correct application state updates.
  • Ensuring components render the expected text, buttons, and accessibility attributes before deployment.
  • Automating regression testing for UI changes in complex React interfaces.
  • Generating test suites that mimic real user behavior rather than brittle unit tests.

Key capabilities

  • Simulates user interactions such as clicking, typing, and pressing keys within a virtual DOM environment.
  • Encourages testing based on what the user sees (user-centric) rather than how the component is implemented.
  • Supports asynchronous rendering scenarios common in React applications.
  • Integrates seamlessly with popular test runners like Jest for automated execution.

Example prompts

  • "Write a React Testing Library test to verify that clicking the 'Submit' button updates the user's name in the state."
  • "Create an integration test ensuring the search bar filters the product list when a user types 'laptop'."
  • "Generate a test suite for a login form that validates error messages appear when invalid credentials are entered."

Tips & gotchas

Ensure your React components use hooks correctly, as Testing Library relies on the component lifecycle to function properly. Avoid using fireEvent directly; prefer higher-level utilities like userEvent which simulate realistic user behavior more accurately.
