Wire harness engineering tutorial for beginners, from 0 to 1

Project overview

The repository now includes a PDF build pipeline for the course content. Run npm run pdf:build to generate the currently configured PDF coursebooks locally. Output files are written to artifacts/pdfs/. Run npm run screenshots:readme if you want to refresh the README preview images. GitHub Actions workflow release-course-pdfs.yml can build the PDFs and publish them to GitHub Releases. The Model Is Smart, The Harness Makes It Reliable

There's a hard truth most people learn the hard way: the strongest model in the world will still fail on real engineering tasks if you don't build a proper environment around it.

You've probably seen this yourself. You give Claude or GPT a task in your repo. It starts well — reads files, writes code, looks productive. Then something goes wrong. It skips a step. It breaks a test. It says "done" but nothing actually works. You spend more time cleaning up than if you'd done it yourself.
