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 jezweb/claude-skills at 1260fa7439.

    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 run Vitest, a fast and extensible unit testing framework designed specifically for modern JavaScript environments. It allows agents to execute test suites, verify code correctness, and generate reports directly within the agent's workflow.

When to use it

  • You need to validate logic in React or Vue applications before deployment.
  • Your development pipeline requires automated regression testing for new feature branches.
  • You want an AI agent to act as a QA engineer by running specific test cases on demand.
  • You are building a CI/CD integration where the agent must confirm tests pass before merging code.

Key capabilities

  • Executes Vitest commands to run unit and end-to-end tests.
  • Parses test output to identify failures, errors, or skipped suites.
  • Supports mocking dependencies and managing complex test environments.
  • Integrates with standard JavaScript testing patterns and assertions.

Example prompts

  • "Run the full test suite for the authentication module and summarize any failures."
  • "Execute only the tests related to the user profile API and report the results."
  • "Update the mock data in mocks/user.json and re-run the affected test cases."

Tips & gotchas

Ensure Vitest is installed as a dev dependency before requesting the agent to run tests. The skill relies on the project's existing configuration files (e.g., vitest.config.ts) to determine scope and environment settings.
