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 obra/superpowers at 8ca22dba9a.

    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 test-driven-development (TDD) skill enables AI agents to write tests before implementing code, ensuring that software meets requirements and remains robust. It supports creating unit tests, integration tests, and automated testing frameworks, helping developers catch bugs early in the development cycle.

When to use it

  • You're building a new feature and want to ensure it works as expected from the start.
  • You need to refactor existing code without introducing regressions.
  • Your team follows agile practices and wants to maintain high-quality code through continuous testing.
  • You are integrating third-party libraries or APIs and need to validate their behavior.

Key capabilities

  • Writing unit tests for individual functions or components
  • Generating test suites based on functional requirements
  • Supporting popular testing frameworks like Jest, Mocha, and PyTest
  • Providing feedback on test coverage and code quality

Example prompts

  • "Write a unit test for the calculateSum function in JavaScript."
  • "Generate integration tests for the user authentication module using Python."
  • "Create a test suite that covers all edge cases for this API endpoint."

Tips & gotchas

  • Ensure your AI agent has access to the relevant testing framework documentation for accurate results.
  • TDD requires discipline; it may take time to fully adopt but leads to more maintainable and reliable code in the long run.
