Codebase to Course

A Claude Code skill that turns any codebase into a beautiful, interactive single-page HTML course.

Point it at a repo. Get back a stunning, self-contained course that teaches how the code works — with scroll-based navigation, animated visualizations, embedded quizzes, and code-with-plain-English side-by-side translations.

Who is this for?

"Vibe coders" — people who build software by instructing AI coding tools in natural language, without a traditional CS education.

You've built something (or found something cool on GitHub). It works. But you don't really understand how it works under the hood. This skill generates a course that teaches you — not by lecturing, but by tracing what happens when you actually use the app.

Your goals are practical, not academic:

Steer AI coding tools better (make smarter architectural decisions)
Detect when AI is wrong (spot hallucinations, catch bad patterns)
Debug when AI gets stuck (break out of bug loops)
Talk to engineers without feeling lost

You're not trying to become a software engineer. You want coding as a superpower.

What the course looks like

The output is a single HTML file — no dependencies, no setup, works offline. It includes:

Scroll-based modules with progress tracking and keyboard navigation
Code ↔ Plain English translations — real code on the left, what it means on the right
Animated visualizations — data flow animations, group chat between components, architecture diagrams
Interactive quizzes that test application not memorization ("You want to add favorites — which files change?")
Glossary tooltips — hover any technical term for a plain-English definition
Warm, distinctive design — not the typical purple-gradient AI look

How to use

Say: "Turn this codebase into an interactive course"

Trigger phrases

"Turn this into a course"
"Explain this codebase interactively"
"Make a course from this project"
"Teach me how this code works"
"Interactive tutorial from this code"

Design philosophy

Build first, understand later

This inverts traditional CS education. The old way: memorize concepts for years → eventually build something → finally see the point (most people quit before step 3). This way: build something → experience it working → now understand how it works.

Show, don't tell

Every screen is at least 50% visual. Max 2-3 sentences per text block. If something can be a diagram, animation, or interactive element — it shouldn't be a paragraph.

Quizzes test doing, not knowing

No "What does API stand for?" Instead: "A user reports stale data after switching pages. Where would you look first?" Quizzes test whether you can use what you learned to solve a new problem.

No recycled metaphors

Each concept gets a metaphor that fits that specific idea. A database is a library with a card catalog. Auth is a bouncer checking IDs. API rate limiting is a nightclub with a capacity limit. Never the same metaphor twice.

Original code only

Code snippets are exact copies from the real codebase — never modified or simplified. The learner should be able to open the actual file and see the same code they learned from.
