Course Market

Find a course, read what it teaches, and download it into your workspace as lesson notebooks you can run and edit.

What you can do

• Search published courses by name, topic, or something a lesson covers.
• See the level, length, and lesson count on every card before you open it.
• Preview a course in full before committing to it.
• Download one into your workspace, then work through it lesson by lesson.
• See at a glance which courses you already have and which have a newer version.

Getting started

• Open Course Market from the activity bar.
• Click a card to read its syllabus, or press Download to get it straight away.
• Downloaded courses land under courses/ and show up in the Learn sidebar.

How a download works

A course arrives as ordinary .lesson.ipynb files plus a small manifest naming the modules and their order. Nothing is hidden or locked: the notebooks are yours to run, edit, and break. Your progress is stored separately from them, so re-downloading a course never wipes what you have learned — though it does replace the notebooks, which is why it asks first.

What it works with

Downloading works on its own. Install Learn to work through a course, and Course Explorer to preview one before downloading.

For contributors

The extension itself is documented in docs/CLAUDE.md with its known gaps in docs/ROADMAP.md. The courses in this repo are a separate subject: how they are written is courses/PRODUCTION-STANDARD.md, which courses exist and why is courses/agent-era-curriculum.md, and how one is scaffolded and then verified against a real kernel is tools/README.md. Starting a course is npm run new-course -- --template, and handing the writing to someone outside this repo goes through courses/LLM-AUTHORING-BRIEF.md, which is the whole contract in one self-contained file. The whole education product across the four extensions is one read in ../extension-edu/docs/handbook.md.
