Hands-on tutorials that teach harness engineering — shaping an AI coding assistant with CLAUDE.md, skills, conventions, and constraints so its output matches how your team actually works.
Every tutorial is a small runnable app. You run the same driving prompt (e.g. "build a todo app") against two versions of the scaffold: one bare, one with a harness. The difference in output is the lesson.
Tutorials are grouped by skill domain. Pick whichever patterns you want to learn — anyone can follow any domain:
