Microsoft’s introduction of Skills for SharePoint AI agents gives the platform’s agent story more structure and clarity. The feature, announced in Extending AI in SharePoint using custom skills (Message ID MC1269209), helps close the gap between the promise of agents and the practical need for repeatable, reliable behaviour in SharePoint Online.
It is important to note that Skills are still in Preview. They should not be treated as production-ready for critical use without rigorous testing and extended support in place.
What Are Skills?
'Skills' is Microsoft’s term for a reusable, repeatable action pattern in SharePoint. The label is a little unusual, but the idea is closer to a person following a standard operating procedure than to a vague human “skill” in the everyday sense.
SharePoint Skills let users create, capture, and quickly reference actions for an agent to use against a library, list, or item. In practice, they help bridge the gap between a one-off AI prompt and a full workflow i.e. the agent can carry out common tasks in a consistent way, with the same expected result each time.
A user with Edit permissions in a site can define a Skill through the agent builder and then reference it in the agent’s instructions. That makes the agent more reliable for routine business tasks, because the behaviour is packaged once and reused many times.
The important distinction is that Skills are not mini-workflows or automation. They can be best thought of as institutionalized AI instructions: structured guidance that sits between ad hoc prompting and true automation.
How would I use the Skills option?
The decision for where and when to use Skills is very straight forward. We would use Skills when:
a task that is a common business pattern managed within a SharePoint site
e.g. review, compare, summarise, organise, fill metadata, manipulate lists/folders...
you need a consistent, repeatable multi-step instructions without code or external tools, and
when governance is SharePoint-native (permissions and compliance policies already apply).
If you need external resources, multi-data types or want to run code then this is not the toolset for you today. If you need these capabilities, you should consider Copilot Studio. See Microsoft's article for deciding on which tool fits your Declarative Agent need.
When can we expect them?
Microsoft's published release is Worldwide preview will begin rolling out in mid-April 2026, and projected completion by early May 2026.
The General Availability (GA) should begin rolling out in late May 2026, with expected completion in early July 2026. Based on previous attempts to roll-out this kind of integration capability (bridging automation, actions, and other services) we expect to see this time-frame slide by a few weeks for GA.
IMPORTANT: Microsoft are releasing this as 'enabled by default' feature with Agents. No opt-out.
What controls and governance options are there?
Skills are governed through the same familiar SharePoint controls used for other site content. When Skills are enabled, SharePoint creates a folder in the deployed agent site’s Site Assets library:
/sites/<site_name>/SiteAssets/Agent Assets/Users with Edit permissions, and the ability to create or edit Agents, can create a Skill. Each Skill is saved as a Markdown (.MD) file within the Agent Assets folder, which makes it a managed content asset rather than a separate system.
Because Skills live in SharePoint, their access is controlled by the site’s existing roles, groups, and permission levels. They can also be governed using Purview classification labels.
In practice, Skills are available for general use by anyone with View/Visitor access or higher on the site.
Risks
WARNING: Skills use can expose (hidden) issues with access and privacy in sites.
The power with Skills comes from being easy for any user to create (if the user has Edit or above permissions). The definitions are stored as content (.MD file) and therefore are governed by existing SharePoint controls.
Ironically, the benefits are also the primary areas of risks that need managing:
the ease of creation and distribution of adverse or poor patterns can propagate rapidly internally,
the current state of site permissions, and poor link hygiene, will quickly lead to over-sharing and (potential) privacy issues.
Recommendation
Skills should be a priority for review, management and adoption with Agents.
SharePoint Skills is one of the missing pieces for enabling business users to scale activity with Agents. It (starts to) fill-in the steps in the spectrum of process-streamlining, through to workflow and automation, for the end-users.
If the goal for your use of Agents in M365 is repeatable behaviour inside SharePoint, then Skills are the natural extension for your implementation.
If you are in process of deploying Agents for adoption and release, include a review cycle to assess and understand the impact for users and to provide relevant guidance for general adoption - before Copilot users start creating Skills files.
