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 wshobson/agents at 46891e7e60.

    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 AI agents with knowledge of common JavaScript testing patterns, such as unit testing, integration testing, and test-driven development (TDD). It enables agents to write effective tests using frameworks like Jest, Mocha, or Jasmine, ensuring code reliability and maintainability.

When to use it

  • You need to implement a robust testing strategy for a JavaScript application.
  • You're refactoring legacy code and want to ensure existing functionality is not broken.
  • Your team follows TDD practices and needs guidance on writing tests before implementing features.
  • You are debugging an issue and want to isolate the root cause through targeted test cases.

Key capabilities

  • Writing unit tests for functions, components, or modules
  • Setting up test environments using frameworks like Jest or Mocha
  • Implementing test-driven development (TDD) workflows
  • Creating mock objects and stubs for testing dependencies
  • Running and debugging test suites effectively

Example prompts

  • "Write a Jest test suite for this React component."
  • "How do I set up TDD in a Node.js project?"
  • "Create a unit test for this function that handles user authentication."

Tips & gotchas

  • Ensure your testing framework is properly installed and configured before running tests.
  • Avoid over-testing; focus on critical paths and edge cases rather than every possible scenario.
