In this hands-on workshop, I walked through how to create a GitHub Copilot Extension from scratch. We explored GitHub’s AI-powered tool ecosystem, built a working extension together, and discussed how to integrate with third-party services to enhance developer workflows.

What We Covered:

• What GitHub Copilot is and how it works
• The purpose and structure of Copilot Extensions
• Key concepts for building your own extension
• Live coding: building, testing, and debugging an extension

Workshop Highlights:

• Using the nickytonline/copilot-extension-workshop repo
• Local development setup and tunneling
• Creating and configuring a GitHub App
• Working with the Copilot Extensions Preview SDK
• Debugging and testing your extension

By the end of the session, participants had a fully functional Copilot Extension running in their own environments—with the tools and knowledge to build more complex, custom integrations.

This workshop is especially useful for:

• Developers curious about AI tooling
• Teams looking to customize GitHub Copilot
• Anyone exploring Copilot Extensions as a platform for developer tools
