Creating a GitHub Copilot Skill from Scratch

In this video, we walk through how to create a custom Skill for GitHub Copilot and show how Skills can extend Copilot beyond simple code suggestions. We explore what Copilot Skills are, why they’re powerful, and how we’ve been using them day-to-day to boost productivity. Using the Copilot CLI, we build a Skill from scratch, explain the core concepts along the way, and share lessons learned from real-world usage on our team. Whether you’re curious about Copilot extensibility, experimenting with AI-assisted workflows, or looking to customize Copilot for your own needs, this video will give you a practical, hands-on starting point. 👇 What you’ll learn: What a GitHub Copilot Skill is How Skills work with Copilot and Copilot CLI How to build and test a custom Skill Real-world insights from using Copilot Skills on a Microsoft product team 👍 If you found this useful, don’t forget to like, subscribe, and let us know what kind of Copilot extensions you’d like to see next. 💝 Join this channel to get access to perks: https://www.youtube.com/channel/Geral... 🛑 Don't forget to subscribe to my channel for more cool content: https://www.youtube.com/GeraldVerslui... 🔗 Links Sample code repository: https://github.com/PureWeen/aquickskill ⏱ Timestamps 00:00 - Create custom GitHub Copilot Skills 02:07 - Copilot CLI YOLO mode 02:57 - Build a Skill to use PR artifacts on your project 03:57 - Going over the process of installing a MAUI version with Copilot 13:00 - Turn this into a Skill 15:25 - Test the Skill 21:43 - Wrapping up #githubcopilot #copilotcli #skills #ai
