Copilot Studio's new agent builder introduced support for skills, reusable, markdown-based instructions that load on demand instead of living crammed into a single instructions box. This session uses Skill Buddy, a real community project built around a Copilot Studio agent, a SharePoint Skills Catalog, and a Canvas app, to show what skills actually look like in practice and why they're a better pattern than the old one-agent-does-everything approach.
