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 thebushidocollective/han at 19caa51d5f.

    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 access to established Jest testing patterns. It helps ensure code quality and maintainability by applying common, effective strategies for writing tests. The patterns cover various aspects of testing, including component rendering, event handling, and API interactions within a JavaScript project.

When to use it

  • When refactoring existing test suites to improve readability and efficiency.
  • During the development of new components or features where consistent testing practices are desired.
  • To ensure that tests accurately reflect the intended behavior of code changes.
  • For onboarding new developers to a project and establishing a baseline for testing conventions.

Key capabilities

  • Provides established Jest testing patterns
  • Promotes code quality
  • Enhances test suite maintainability
  • Supports component rendering tests
  • Facilitates event handling tests
  • Enables API interaction testing

Example prompts

  • "Apply the 'render and check' pattern to this React component."
  • "Show me an example of a Jest test for mocking an API call."
  • “What is the best way to test a form submission with Jest?”

Tips & gotchas

This skill assumes familiarity with basic Jest concepts. To get the most out of it, have existing tests or code snippets ready to apply the suggested patterns to.
