About

Teams SDK covers Teams apps, AI agents, message extensions and calls to Microsoft Graph, and it replaces the earlier Teams AI name. Each language has its own repository, with TypeScript, C# and Python listed. The Teams Developer CLI creates an agent from a template through npx, and the README notes that the main branch now holds v2 while v1 moved to a release branch. The sample app reads the signed-in user's profile through Graph and sends a reply.

Use cases: team-chat, api-integration
