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 existential-birds/beagle at d1a74899fb.

    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

vitest-testing

What it does

This skill enables AI agents to execute Vitest tests directly within their environment, allowing for automated verification of code changes. It streamlines the testing workflow by integrating the popular Vitest runner into the agent's operational capabilities.

When to use it

  • Validate logic updates in JavaScript or TypeScript applications before merging pull requests.
  • Run regression suites to ensure new features do not break existing functionality.
  • Generate test coverage reports to identify untested code paths during development sprints.
  • Automate unit tests for microservices where rapid feedback on build integrity is critical.

Key capabilities

  • Executes Vitest commands directly in the agent's runtime environment.
  • Supports running specific test files or entire suites via command-line arguments.
  • Captures and reports test results, including pass/fail statuses and error logs.
  • Integrates seamlessly with projects already utilizing the Vitest ecosystem.

Example prompts

  • "Run all tests in the src/utils directory using Vitest and summarize any failures."
  • "Execute the specific test file auth.test.ts to verify the new login flow implementation."
  • "Generate a coverage report for the current branch and highlight modules with less than 80% coverage."

Tips & gotchas

Ensure your project has Vitest installed as a dev dependency before invoking this skill, or the agent will fail to locate the binary. For large codebases, consider instructing the agent to run tests in parallel using the --run flag for faster execution times.
