Microsoft Developer introduces Microsoft Copilot Studio fundamentals for building custom agents, including how instructions, knowledge, tools, skills, memory, and MCP fit together, plus an overview of the new GitHub Copilot harness for reasoning-heavy, multi-step agent scenarios.

Overview

The video focuses on getting started with Microsoft Copilot Studio and the core building blocks used to create more capable, agentic solutions.

Copilot Studio fundamentals for custom agents

It covers the fundamentals of building custom agents for an organisation, with emphasis on how these pieces work together:

Instructions: defining how the agent should behave and respond
Knowledge: grounding the agent in organisational content
Tools: enabling the agent to take actions via connected capabilities
Skills: reusable capabilities the agent can invoke
Memory: retaining relevant context across interactions
MCP (Model Context Protocol): how MCP fits into the overall agentic solution design

GitHub Copilot harness (new)

The video also introduces the new GitHub Copilot harness, positioned for reasoning-heavy, multi-step scenarios, and explains how it relates to building more capable agentic solutions alongside the Copilot Studio building blocks.
