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 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

This skill generates unit tests for provided code snippets. It aims to create comprehensive test suites, including edge cases and boundary conditions, to ensure code quality and reliability. The generated tests are designed to be easily integrated into existing testing frameworks.

When to use it

  • Automated Testing: Quickly generate a baseline set of unit tests when starting development on a new software component.
  • Code Refactoring: Create tests after refactoring existing code to verify functionality remains unchanged.
  • Legacy Code Coverage: Generate initial test coverage for older codebases lacking automated testing.
  • Learning and Examples: Understand how to write unit tests by examining the generated examples.

Key capabilities

  • Generates unit tests from code snippets.
  • Supports various programming languages (unspecified).
  • Creates comprehensive test suites, including edge cases.
  • Designed for integration with existing testing frameworks.

Example prompts

  • "Write unit tests for this Python function: def add(a, b): return a + b"
  • "Generate unit tests in JavaScript for the following code: function calculateArea(width, height) { return width * height; }"
  • “Create a test suite for this Java class: [paste class definition here]”

Tips & gotchas

The quality of generated tests depends heavily on the clarity and completeness of the provided code. Review the generated tests carefully and adapt them to your specific testing needs.
