The June announcement of Copilot Studio’s new experience marks a pivotal shift: Topics and Child Agents are no longer supported. If you’ve architected agents using these approaches, it’s time to embrace Skills as the new standard. Skills fundamentally change how you build agent behavior. Instead of monolithic components, Skills load rich logic on-demand only the Skill name and description are preloaded into the context window, while the full skill executes only when needed.

Copilot Studio now supports Skills as the core way to build agent behavior. With Skills, your agent can load rich logic on demand — only the Skill name and description are preloaded into the context window, while the full skill is fetched only when it runs. Anthropic publishes the Skills collection at https://www.skills.sh. This post covers the skill-creatorskill to help create or modify skills. This Skill helps generate complete SKILL.md packages, including embedded scripts and supporting files.

It was a privilege to be able to attend the M365 Conference in Orlando from 21st to 23rd April 2026. At the conference, one announcement that stood out was Skills in SharePoint, now in preview. What is a SharePoint Skill? SharePoint Skills are reusable, AI-powered workflows that encode business logic in natural language, native to SharePoint. Think of them as the difference between asking a question and capturing a repeatable process.
