Microsoft says Copilot Skills will expand into Copilot Chat during November 2026. A skill is reusable know-how: an instruction or workflow Copilot can apply consistently to a task. Users will be able to create skills in natural language and find skills shared by colleagues or their organisation. The rollout is planned for November, but availability can vary by tenant.
What are Copilot Skills?
A Copilot Skill packages repeatable steps or expertise so Copilot can use them again, rather than making staff rebuild the same instructions in every conversation. Microsoft describes skills as reusable capabilities that help teams work more consistently and share know-how.
For a small business, that might mean a standard way to prepare a meeting brief, summarise a support issue, or create a first draft from approved information. A skill can help make the process repeatable; a person should still check the result before relying on it or sending it outside the business.
What is changing in Copilot Chat?
Microsoft’s October update says skills are expanding from Copilot Cowork into Copilot Chat. During the November rollout, users will be able to create skills using natural language, discover skills shared by colleagues or their organisation in the Agents and Plugins area, and choose when to use them. Microsoft has not promised that every tenant will receive the change on the same day.
This is a specific Copilot capability update, not a change to the Microsoft 365 app names or the Frontier preview programme. KES has already covered what Copilot Chat includes, how Frontier previews work, and permission checks before a Copilot rollout.
What should a business check before using shared skills?
Treat a skill like a reusable business process: give it an owner, test it on ordinary work, and make sure people know what it is intended to do. Start with a low-risk task and compare the output with your normal process before relying on it for client, legal, financial, or security-sensitive work.
- Choose one repeatable task with a clear expected result, such as preparing a meeting brief or formatting an internal summary.
- Check the skill’s instructions and source material. Do not put passwords, client secrets, or other sensitive information into a reusable instruction.
- Confirm who created or approved the skill, who can use it, and how staff should report a poor or unexpected result.
- Review the relevant Microsoft 365 admin controls. Microsoft documents options to install or manage skills for everyone or selected users and groups, while publisher settings can govern which plugin categories users can access.
- Keep a human review step for anything that will be sent externally, change business records, or influence a significant decision.
Microsoft’s admin guidance describes controls for skills and plugins in the Microsoft 365 admin centre. The exact controls depend on how a skill is provided, so check the current settings and Message centre notices in your own tenant rather than assuming every user-created skill is centrally managed in the same way.
Does a Copilot Skill give users new data access?
Do not treat a skill as a permission change. Review the user’s existing access to the files and services Copilot can use, and separately review any connected tools or plugins the skill relies on. KES’s Copilot permissions guide explains why access reviews matter before expanding AI use.
When will Copilot Skills reach my tenant?
Microsoft’s October 2026 Copilot roundup says the expansion into Copilot Chat rolls out in November. That is a planned rollout window, not a guarantee that the feature is already available to every user. Check your Microsoft 365 Message centre and the Copilot interface for tenant-specific timing and any licensing or prerequisite notes.
Copilot Skills: quick answers
Can users create a Copilot Skill by describing it?
Microsoft says users will be able to create skills in Copilot Chat using natural language as the November rollout progresses. Availability may vary by tenant.
Can administrators limit who uses a skill?
Microsoft’s admin centre guidance includes options to make managed skills available to all users or selected users and groups. Administrators can also control access to plugin categories. Check the specific skill and tenant controls before rollout.
Should we use Skills for every task?
No. Start with a repeatable, low-risk task where consistent steps are useful. Keep human review for sensitive information, external communications, and consequential decisions.
