Automated safety checks
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.

About this skill
What it does
This skill provides automated testing capabilities for React components using React Testing Library. It allows you to write and execute tests that simulate user interactions with your application, verifying the correct behavior of UI elements and ensuring a stable frontend experience. The skill focuses on rendering components and asserting their rendered output based on user actions.
When to use it
- Automated Regression Testing: Run existing test suites after code changes to ensure no functionality has been broken.
- Component Development: Test individual React components in isolation as you build them, catching errors early.
- UI Feature Verification: Validate that new UI features behave as expected under various user scenarios.
- Continuous Integration/CI Pipelines: Integrate tests into your CI pipeline to automatically run tests on every code commit.
Key capabilities
- Rendering React components within a testing environment.
- Simulating user interactions (clicks, typing, etc.).
- Asserting the rendered output of components based on actions.
- Executing existing test suites.
Example prompts
- "Run all tests for the
src/components/Button.jsfile." - "Execute the test suite located at
/tests/Login.test.js." - “Render and test the component at
src/components/UserProfile.jsto verify that the 'Edit' button is visible.”
Tips & gotchas
- This skill requires a working React project with existing tests written using React Testing Library. It doesn’t create tests; it executes them.
