mfranzon/tdd ? reverse-engineered prompt

Build me a Claude Code skill called /tdd that helps me do strict test driven development in a really guided way.

I want to be able to give it either a markdown plan file or a short feature description, and then have it break the work into small testable steps, show me the increments, and ask for approval before it starts. For each step, it should write a failing test first, run it to confirm it fails, then write the smallest amount of code to make it pass, and then refactor if needed. It should work with common setups like Python with pytest, TypeScript with vitest, and Go with the standard testing tools.

Please make it write directly to the real source and test files, keep going automatically when tests are green, and only pause when it needs my review or something breaks. At the end, give me a short summary of what it built, what tests ran, and any next steps or gaps it noticed. If you need to check current docs online, go ahead.
