Copilot Cowork - Let's Build Some Skills

Overview:

Once you have used Cowork for a few weeks you start to see the patterns: the same kind of email, the same kind of summary, the same kind of report, every single week. This session is about turning those patterns into reusable skills so you stop reinventing the wheel. We will start with what a skill actually is: a SKILL.md file that lives in your OneDrive under /Documents/Cowork/skills/, picked up automatically by Cowork at the start of every conversation. We will then build several skills together, from a simple one (a weekly status update with the tone and structure you prefer) through to a more advanced one that combines enterprise search, file creation, and a fixed approval flow. We will look at how to write skill instructions Cowork actually follows, how to test and iterate, and how to debug the cases where it does not behave the way you expected. We will also cover skill governance: where the limits are (50 custom skills per user), how skills interact with the built-in ones, what happens when a skill collides with your tenant policies, and how to share useful skills responsibly with colleagues. You will leave with a working skill of your own and a clear method for building more.

Why you should Attend:

The moment you start using Cowork seriously, you notice the same thing: you are typing the same instructions over and over. "Use this tone. Use this structure. Always include a summary at the top. Never use bullet points in client emails." That is fine the first three times. By the thirtieth, it is a problem. Skills are the answer. A skill is a reusable set of instructions that captures how you want a piece of work done, so Cowork applies it consistently every time. Without skills, every conversation starts from scratch and quality drifts. With skills, your weekly status update, your customer follow-up, and your project kickoff all come out the way you want, without you having to remember the recipe. This session shows you how to build skills that actually work, where to put them, and how to share them across your team so the whole organisation benefits, not just you.

Areas Covered in the Session:

• What a skill is, and why it changes how you work with Cowork
• Where skills live: OneDrive, SKILL.md, and the auto-discovery flow
• Anatomy of a good skill: name, description, instructions, examples
• Writing instructions Cowork actually follows (and why some get ignored)
• Building skill #1: a weekly status update in your tone and structure
• Building skill #2: a customer follow-up email with approval gates
• Building skill #3: a multi-step skill that uses files, search, and email
• Testing, iterating, and debugging skills that misbehave
• Skill limits, governance, and how skills interact with tenant policies
• Sharing skills with your team without creating a maintenance nightmare
