Copilot / Skills
Copilot can use skills now, but only in 2 file formats
How to upload skills into a Copilot agent, and which file formats it accepts
SUMMARY
Copilot agents can now use skills. You upload a skill as a SKILL.md file or as a zip file that contains the SKILL.md, and it works across your agents.

Before you start
Why it matters
There are 3 reasons to learn this process:
You can upload the skills you saved from AI creators and use them at work.
You can share skills across agents and with your teammates.
You can apply one skill across your whole Copilot instance.
Here is my example. I have a skill that makes Copilot stop talking so much. I call it my "shut up" skill. I use it in all my agents, because Custom Instructions was not enough to control it.
If your company pays for Copilot, the feature you're missing out on is that Copilot can now use skills.
You have probably watched people share Claude, ChatGPT and Gemini skills and wished you could use them in your 9-5. Now you can!
There is one catch.
You cannot upload a Claude, ChatGPT or Gemini skill into Copilot.
Copilot needs the skill in a specific format with two variations, which I'll walk you through.
First, what is a skill?
A skill is a set of saved instructions that an AI tool follows for a specific job.
Every skill is a markdown file with three parts: a name, a description, and instructions that say what the skill does.
Here's how to upload a skill into Copilot.
Step 1: Open your agent
Go to Agents.
Click Edit on the agent that needs the skill.
Then open Skills.
Step 2: Put the skill in one of 2 formats
This is the step to remember. Copilot needs your skill as one of these:
A markdown file named SKILL.md, or
A zip file that contains the SKILL.md. Name the zip with the actual name of the skill.
It looks redundant. But if your Copilot behaves like mine, this is the only way it accepts a skill.
A SKILL.md has three parts. This is a short sample so you can see the shape. It is a sample, not my real file.
Below is an example of my "Concise Copilot" agent that makes Copilot shut up โ or answer concisely.

Caution: Do not upload a foreign skill file without checking the contents of the skill โ especially since you'll be using it in a work environment.
Step 3: Upload the skill
In the Skills area of your agent, add your SKILL.md file or your zip file.
Then test the agent with a normal question and check that it follows the skill.
Step 4: Reuse the skill throughout your environment
After the skill works in one agent, add it to your other agents.
Share the same file with your teammates so everyone uses the same skill.

REMAINING QUESTIONS
1. Can I upload my Claude, ChatGPT or Gemini skills directly into Copilot?
Not as they are. This is the catch. Copilot needs the skill as a SKILL.md file or as a zip file that contains the SKILL.md and carries the skill name. The content of the skill can stay the same. The packaging is what changes.
2. Why not use Custom Instructions instead?
Custom Instructions was not enough for me. A skill is a file that I can reuse and share. One file works in all my agents and I can give it to a teammate.
3. Is it safe to upload a skill that someone else made?
Read it first. A skill is plain text with a name, a description and instructions. You can read all of it in a few minutes. If you only upload skills that you understand, you know what your agent will do. If you are not sure that your company allows custom skills, ask your IT team before you share one across a team.
