Based on an idea by Ahmed Nagdy
Twelve modules with terminal simulations, forms for configuration files, and quizzes. Nothing to install.
Try it first, install later
Your browser runs a terminal simulation where you work through hooks, skills, and slash commands — no install, no API key.
Configurations you can take with you
Forms produce CLAUDE.md, hook entries, and plugin configurations you can drop into your project unchanged.
Check what actually stuck
Every module ends with a quiz. A wrong answer gets you the reasoning, not just the right option.
Begin at the beginning
Twelve modules from beginner to advanced — the usual place to start.
