Microsoft Reactor

Great developer training shouldn't require a team of curriculum engineers.

In this hands-on Microsoft Reactor series, you'll learn to design, build, review, and publish your own GitHub Skills-style exercises — interactive, self-paced, issue-driven learning experiences that live right inside a GitHub repository — using the open-source gh-skills-builder GitHub Copilot plugin. Across the series we'll take a raw idea, workshop, or demo and turn it into a complete, validated learning journey.

You'll see how the plugin's custom agents and Agent Skills collaborate to handle each stage of the exercise lifecycle, so you can focus on what you want learners to master instead of the plumbing behind it.
