Visual Studio Code 1.108, the latest version of Microsoft’s popular code editor, introduces support for Agent Skills, a new feature that allows users to teach the GitHub Copilot coding agent new capabilities and provide domain-specific knowledge.
VS Code 1.108, also known as the December 2025 release, arrived January 8. Developers can access it for Windows, Linux, and Mac from code.visualstudio.com.
An experimental feature, Agent Skills are folders of scripts, instructions, and resources that GitHub Copilot can load when relevant to perform specialized tasks, according to Microsoft. Skills are stored in directories with a SKILL.md file that defines the skill’s behavior and automatically detected from the .github/skills folder. They are then loaded on-demand into the chat context when relevant for the developer’s request.
