Microsoft calls the same idea agents in one product and skills in another, which leaves many Copilot users confused. This episode explains in plain English what a Copilot skill is, where it lives in Copilot Chat, Copilot Studio and Copilot Cowork, and how beginners can build their first reliable, reusable skill.

In this episode
  • 00:00 – Why skills are confusing
  • 00:41 – What a Copilot skill is
  • 01:45 – Where skills live
  • 03:23 – Creating a skill with Agent Builder
  • 05:02 – Skills in Copilot Studio
  • 06:42 – Skills in Copilot Cowork
  • 08:36 – What makes a good skill
  • 10:50 – Skills vs. instructions vs. workflows

Key takeaways
  • A Copilot skill is a reusable instruction set made of a name, a trigger description and step-by-step instructions that runs only when a request matches.
  • Skills live in three homes: Agent Builder in Copilot Chat for no-code creation, Copilot Studio for Markdown files with scripts, and Copilot Cowork for skill files in OneDrive.
  • Good skills have precise names, specific triggers, short instructions, a defined output format and explicit rules, and they improve through testing and iteration.

Worth quoting

“A copilot skill is a reusable instruction set for AI. Think of it like writing a job description for a temporary worker.” – Mirko Peters (00:46)

“A skill is not a chatbot that you sit and talk to. It's a specialist that only activates when needed.” – Mirko Peters (01:13)
