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 microsoft-foundry/foundry-agent-webapp at f6cb362901.

    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 TypeScript unit tests for provided code. It leverages Jest as the testing framework and focuses on creating test files with assertions to verify expected behavior. The generated tests include setup, function calls, and assertions based on the input code's functionality.

When to use it

  • You have existing JavaScript or TypeScript code that needs automated unit tests.
  • You want to quickly generate a baseline set of tests for new functions or modules.
  • You are refactoring code and need to ensure existing functionality remains intact.
  • You're learning about testing in TypeScript and want examples.

Key capabilities

  • Generates Jest-compatible test files.
  • Creates assertions to verify function behavior.
  • Supports TypeScript code input.
  • Includes setup for the testing environment.

Example prompts

  • "Write unit tests for this TypeScript function: function add(a: number, b: number): number { return a + b; }"
  • "Generate Jest tests for this component: <MyComponent />"
  • "Create a test file with assertions for the following code snippet."

Tips & gotchas

  • This skill assumes familiarity with Jest and TypeScript. You may need to adjust generated tests based on your project's specific testing environment.
