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 matteocervelli/llms at 1e1f2089eb.

    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

The jest-generator skill automatically generates Jest testing files based on provided code. It simplifies test creation by producing a basic, runnable test suite structure, saving developers time and effort in setting up initial tests for JavaScript projects. This includes generating test file content with common assertions.

When to use it

  • New Project Setup: Quickly generate a starting point for testing when beginning a new JavaScript project.
  • Rapid Prototyping: Generate basic tests alongside code during rapid development cycles, ensuring some level of automated verification.
  • Initial Test Coverage: Create initial test files to establish a foundation for more comprehensive testing later on.
  • Code Refactoring: When refactoring existing code, use the skill to generate new tests that reflect the changes.

Key capabilities

  • Generates Jest test files based on provided JavaScript code.
  • Creates basic test structures with common assertions.
  • Provides a starting point for building comprehensive test suites.

Example prompts

  • "Generate Jest tests for this React component: function MyComponent() { ... }"
  • "Create a Jest file for the function calculateSum(a, b)."
  • "Generate a basic test suite for this JavaScript module: [module content]"

Tips & gotchas

The generated tests are a starting point and may require customization to cover all edge cases and specific scenarios. Ensure you have Node.js and Jest installed in your project environment before using the skill.
