Stop wiring infrastructure, start building agents

https://aka.ms/foundry-portal https://aka.ms/InsideMicrosoftFoundryPlaylist Every agent project seems to start the same way containers, scaling, state, auth. Most of the time, you don't need any of it. You rebuild Sparkles as a prompt agent: a model, instructions, and the Cupcake Store MCP tools, defined once and versioned in Microsoft Foundry. No container, no server, no pipeline. Then you hit the edge where a prompt agent isn't enough, such as custom orchestration or your own framework, and move the same agent to a hosted agent. Callers still invoke it by name. By the end, you'll know which one to reach for first, and when to switch. 0:00 - Scale Complex Cupcake Orders 0:34 - Introducing the Copilot Harness 1:07 - Configure Harness Tools 1:38 - Add Reusable Agent Skills 2:44 - Enable Bulk and Party Orders 3:18 - Process Orders from CSV Data 4:25 - Configure the Agent with YAML 4:59 - Define Skills and MCP Tools 5:32 - Scale Without Managing Infrastructure #copilot #harness #microsoft #foundry
