Extending AI in SharePoint using custom skills

Custom skills for AI in SharePoint enable users with edit permissions to create reusable, multi-step AI tasks using natural language, stored as Markdown files in the site’s Agent Assets library. Rolling out from April to July 2026, this feature respects existing permissions and requires no tenant-level activation. We’re introducing custom skills for AI in SharePoint, which let users teach AI in SharePoint how to perform common business tasks in a consistent, repeatable way. With skills, organizations can tailor AI behavior to their own documents, standards, and processes—such as reviewing compliance documents or offer letters—without writing code or using external tools. This update helps reduce manual effort and makes AI results more reliable for everyday SharePoint work. This message is associated with Roadmap ID 559800. When this will happen: Public Preview (Worldwide): We will begin rolling out in mid-April 2026 and expect to complete by early May 2026. General Availability (Worldwide): We will begin rolling out in late May 2026 and expect to complete by early July 2026. How this affects your organization: Who is affected: Users of AI in SharePoint SharePoint site owners and admins Users with edit permissions on SharePoint sites What will happen: Users with edit permissions can create custom skills using natural language within AI in SharePoint. Skills allow users to define reusable, multi‑step AI instructions for common business tasks (for example, reviewing compliance documents or offer letters). AI in SharePoint can automatically select relevant skills from the current site based on a user’s query, or users can invoke a skill by name. Skills are saved as Markdown (.md) files in the site’s Agent Assets library (/Agent Assets/Skills/<skill-name>/SKILLmd) and are governed by existing SharePoint permissions and compliance policies. Skills reuse native AI in SharePoint capabilities (content understanding, list manipulation, folder organization, and other supported SharePoint actions). Skills cannot connect to external systems or execute custom code. The feature is enabled by default and has no separate tenant‑level on/off toggle. Existing SharePoint permissions are respected; users cannot perform actions they do not already have permission to do. What you can do to prepare: No action is required to enable […]
