Let's Create a GitHub Copilot Extension! - Nick Taylor, Pomerium

Presented at All Things Open AI 2025
Presented by Nick Taylor - Pomerium

Title: Let's Create a GitHub Copilot Extension!
Abstract: Get hands-on in this talk where we'll create a GitHub Copilot Extension from scratch.

We'll use the Copilot Extensions SDK, https://github.com/copilot-extensions/preview-sdk.js, and Hono.js, covering best practices like payload validation and progress notifications and error handling.

We'll also go through how to set up a dev environment for debugging, including port forwarding to expose your extension during development as well as the Node.js debugger.

By the end, we'll have a working Copilot extension that the audience can try out live.
