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 callstack/react-native-testing-library at b87a246e68.

    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 write and execute unit tests for React Native applications using the testing library ecosystem. It streamlines the verification of component behavior, navigation flows, and native module interactions across iOS and Android environments.

When to use it

  • Automate regression testing: Ensure new code changes do not break existing features in a cross-platform mobile app.
  • Validate UI components: Verify that screens render correctly with specific props and handle user inputs as expected.
  • Test navigation logic: Confirm that deep linking, stack transitions, and parameter passing work flawlessly on both platforms.
  • Mock native dependencies: Isolate business logic from complex native modules like camera or analytics during the testing phase.

Key capabilities

  • Generates test suites compatible with React Native's architecture.
  • Supports mocking of native modules to prevent environment-specific failures.
  • Facilitates snapshot testing for UI consistency across different devices.
  • Integrates seamlessly with standard CI/CD pipelines for mobile development.

Example prompts

  • "Create a unit test for the UserProfile component that verifies the avatar displays correctly when a user ID is provided."
  • "Write an integration test to ensure navigation from the Home screen to the Settings screen passes the correct theme parameter."
  • "Generate a mock for the CameraModule and write a test case where the app handles camera permission denial gracefully."

Tips & gotchas

Ensure your development environment has the necessary native simulators or emulators configured, as some tests may require actual device access. Be mindful that complex native interactions might need additional configuration to run reliably in automated testing environments.
