+## Copilot agents
+
+Agents are scoped versions of Microsoft 365 Copilot that act as AI assistants to automate and run business processes. Agents enable you to bring custom knowledge, skills, and process automation into Microsoft 365 Copilot for your organizational needs. You can optimize agents for specific tasks, such as summarize meetings, list action items, and take actions such as updating records. Declarative agents, custom engine agents, plugin promoted declarative agents and all other store copilot agents are supported in Teams meetings. For more information, see [your extensibility options for Microsoft 365 Copilot](/microsoft-365-copilot/extensibility/decision-guide).

 ## Message extensions
 
 Message extensions allow the users to interact with your web service through buttons and forms in the Teams client. Users can search or initiate actions in an external system from the compose message area, the command box, or directly from a message. You can send back the results of that interaction to the Teams client in the form of a richly formatted card. Implementing message extensions for meeting chats is no different than regular chats. To implement message extension, start with [message extensions](/microsoftteams/platform/messaging-extensions/what-are-messaging-extensions?tabs=dotnet).
