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 bobmatnyc/claude-mpm-skills at 718070a7d6.

    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 enables AI agents to execute Test-Driven Development (TDD) workflows, ensuring code quality by generating tests before implementation. It guides the agent through writing failing tests first, then coding the minimum solution to pass them, and finally refactoring for maintainability.

When to use it

  • Preventing regressions: Before deploying critical updates to an existing codebase where breaking changes must be avoided.
  • Learning new libraries: When integrating unfamiliar frameworks or APIs to ensure correct usage patterns immediately.
  • Refactoring legacy code: To safely modify complex functions while maintaining a safety net of passing assertions.
  • Enforcing standards: Guaranteeing that all generated code adheres to specific architectural constraints or edge-case requirements.

Key capabilities

  • Generates unit tests prior to writing production logic.
  • Iteratively refactors code to improve structure without breaking tests.
  • Validates implementation against defined specifications and edge cases.
  • Provides immediate feedback on code correctness before finalization.

Example prompts

  • "Apply TDD to create a Python function that calculates compound interest, writing the test suite first."
  • "Refactor this legacy JavaScript module using Test-Driven Development principles to improve readability."
  • "Generate failing tests for a new REST API endpoint, then implement the logic to make them pass."

Tips & gotchas

Ensure you provide clear acceptance criteria or expected inputs/outputs when requesting test generation, as vague requirements lead to weak test cases. This workflow is most effective when the AI agent has access to the full project context to understand dependencies and existing patterns.
