Install a provided skill

Tool: Cowork

Every Cowork scenario starts the same way: you download a skill and get it running. A skill is a set of instructions Cowork follows - it ships either as a single SKILL.md or as a .zip folder, and you upload it once.

Steps

1. Download the skill from the scenario's build page. Leave it exactly as it downloads - a .md file, or a .zip (don't unzip it).
2. Open Cowork at copilot.cloud.microsoft/cowork.
3. In the left menu, choose Customize → Skills.
4. Select the arrow next to Add, then Upload skill, and drag in the file the build page gave you.
5. Start a new session - Cowork only discovers skills when a session begins.
6. Name the skill in your first message so Cowork loads it, for example: "Introduce yourself."

You'll know it worked when... the skill appears under Your skills on the Customize page, and it responds when you name it.

Two things to get right

• If it's a .zip, upload the whole zip - not the SKILL.md inside it. The zip carries the reference files the skill needs; a lone SKILL.md from inside a zip can't see them.
• Start a new session after installing. A skill added mid-session stays invisible until you begin a fresh one.

Apply it to your scenario

The build page names the skill to install and the first thing to say once it's loaded. Install it, start a new session, and say hello before anything else.
