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:

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:

Code translation block Animated data flow Interactive quiz Glossary tooltip

How to use

As a Claude Code skill

  1. Copy the codebase-to-course folder into ~/.claude/skills/
  2. Open any project in Claude Code
  3. Say: "Turn this codebase into an interactive course"

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.

Codebase-to-course
What is this?A Claude Code skill that takes any codebase and turns it into a single, self-contained HTML course that teaches how the code actually works, aimed at non-technical 'vibe coders'.
Is this a Claude Code skill or a standalone app?It is a skill folder you drop into Claude Code's skills directory, not a separate application. Claude Code generates the HTML course for you when you ask it to.
How do I start using it?Copy the 'codebase-to-course' folder into ~/.claude/skills/, open any project in Claude Code, and say 'Turn this codebase into an interactive course'.
Do I need anything besides Claude Code to run it?No extra tooling is needed for the skill itself; it just requires Claude Code with skills support. The resulting course is a single HTML file with no dependencies.
Does it modify or simplify the code it teaches from?No — it only pulls exact snippets from the real codebase; nothing is rewritten or simplified, so what you see matches the actual files.
Who is this really for?It's built for 'vibe coders' who build software by instructing AI tools in natural language and want to understand their code without formal CS training, not for people trying to become traditional software engineers.
What platforms can I use this on?Since it runs inside Claude Code and outputs a plain offline HTML file, it works wherever Claude Code runs, including Linux, macOS, and Windows.
Does the generated course need an internet connection?No, the course is fully self-contained and works offline once generated.
What kind of content does the generated course include?It includes scroll-based modules with progress tracking, code-to-plain-English side-by-side translations, animated visualizations like data flow diagrams, interactive application-based quizzes, and glossary tooltips for technical terms.
How do quizzes in the course differ from typical tutorials?Instead of testing memorized definitions, quizzes pose practical scenarios like 'A user reports stale data after switching pages — where would you look first?' to test applied understanding.
What trigger phrases does Claude Code respond to for this skill?Phrases like 'Turn this into a course', 'Explain this codebase interactively', 'Make a course from this project', and 'Teach me how this code works' all invoke the skill.
Why does the design avoid typical AI-generated visuals?The author deliberately aims for a 'warm, distinctive design' instead of the common purple-gradient look associated with AI-made interfaces, and uses a unique metaphor for every concept rather than recycling the same analogy.
What are similar projects?ai-guide, hello-sdd, explainer, Manware-s-AI-Learning-Toolkit, darwin-skill, app-ideas, youmightnotneedjquery, electron-api-demos
Which topics is it in?self-evolving, knowledge-base, skill, beginner-friendly, css, learning-resources, documentation, html, learning, agent-skills, tutorial, gui
