teardown

What is teardown

teardown is an open-source (MIT) Claude Code skill that turns any machine, such as an engine or a mechanical watch, into an interactive 3D simulation page you can take apart. The generated pages work offline. It requires Node.js 20+ and Playwright.

How to use

1. Make sure you have Node.js 20 or newer (plus ffmpeg for video and Python 3 for sound).
2. Install the skill:npx skills add elvarofficial/teardown -g -a claude-code.
3. Once, in the installed folder, runnpm install && npx playwright install chromium.
4. Ask Claude Code in plain words, e.g.
5. "Build me a simulator of a 4-stroke motorcycle engine I can take apart." Claude builds one offline HTML page: the machine runs in the middle, panels read real numbers and buttons open the part doing the work.
6. Optionally try the bundled examples withnode sims/build.mjs v8-live,cessna-liveorstrandbeest-live, or ask for a recorded video tour.

Use cases

• Explaining how a machine works with an interactive 3D simulator you can take apart Creating offline, single-file HTML teaching demos of engines, watches or hydraulic arms Recording a 60 fps video tour of a machine with procedural sound Learning mechanical engineering concepts by exploring live parts and numbers
