What you get

  • A model-invoked red-green-refactor loop: the agent writes a failing test first, makes it pass with the smallest change, then refactors, and refuses to skip steps.
  • Part of Matt Pocock's engineering skills alongside diagnosing-bugs, implement, to-spec and code-review.

Install the TDD (Matt Pocock) skill

Pick your agent. The wrapper only tells your agent how to start a session. The skill's instructions arrive with each session, after your access is checked.

  1. Sign in once from your terminal.

    Terminal
    skillgild login
  2. Install this skill for Claude Code.

    Terminal
    skillgild install tdd --agent claude-code
  3. Register the SkillGild MCP server with Claude Code.

    Terminal
    claude mcp add --scope user skillgild -- $(command -v skillgild) mcp

How it runs

  1. Your agent starts a session. SkillGild checks your access and allowance, counts one run, and sends the skill's instructions for this task.
  2. Your agent does the work with its own model and tools, in your project. SkillGild makes no AI model call.

Use it from code

Start a session, follow its guide, then end it. Create an API key under Account and pass it as a bearer token.

Terminal
# Prints the session ID, its tools and the instructions for your agent
skillgild session tdd
skillgild end <session-id>

Questions

How do I install TDD (Matt Pocock) in Claude Code?

Run skillgild install tdd --agent claude-code and connect the SkillGild MCP server (skillgild mcp). When a task matches, your agent starts a session, which uses one of your 25 free runs this month, and follows the skill's instructions. Use --agent codex, cursor or gemini-cli for other clients.

Is TDD (Matt Pocock) free?

Yes. It includes 25 free runs every month on SkillGild. TDD (Matt Pocock) is open source (MIT) by Matt Pocock; SkillGild packages it from https://github.com/mattpocock/skills at a pinned commit and credits the author.

Does TDD (Matt Pocock) run on SkillGild?

It runs in your coding agent with your own model. SkillGild checks your monthly allowance and delivers the skill's instructions for each session; it makes no model call and never sees your project unless your agent sends it.

Which agents does TDD (Matt Pocock) work with?

The project lists Claude Code, Codex and other Agent Skills hosts. It is a plain Agent Skills folder (SKILL.md plus supporting files), so any client that reads that format can load it.
