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 pageai-pro/ralph-loop at eba65ebbb0.

    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 guidance and automated checks for following best practices when writing tests with Vitest, a Jest alternative. It helps ensure test suite quality by enforcing consistent patterns, identifying potential issues, and suggesting improvements to existing tests. The skill aims to improve code maintainability and reduce debugging time related to testing.

When to use it

  • New projects: To establish Vitest best practices from the beginning.
  • Refactoring existing test suites: To modernize and improve the quality of older tests.
  • Code reviews: To automatically check for adherence to Vitest best practice guidelines.
  • Continuous Integration (CI): As part of automated checks in your CI pipeline.

Key capabilities

  • Enforces consistent testing patterns.
  • Identifies potential issues in existing tests.
  • Suggests improvements to test code.
  • Automated checks for Vitest best practices.

Example prompts

  • "Analyze my src/components/Button.test.js file and suggest improvements."
  • "Check this test suite for adherence to Vitest best practice guidelines: tests/unit/User.spec.ts"
  • “Review the following code snippet and identify any potential issues related to Vitest testing practices: [code snippet]”

Tips & gotchas

This skill assumes you are already using Vitest in your project. It is most effective when integrated into a development workflow that prioritizes test quality and maintainability.
