Declarative agents
Declarative agents extend Copilot Chat with a focused role, instructions, knowledge, and capabilities. This module covers the Copilot Chat harness, not the separate Microsoft Copilot harness used for the reasoning-heavy agents and workflows in later labs. The Standard harness is also a separate option.
Compare the authoring paths in Agent Builder, Microsoft 365 Agents Toolkit, and Microsoft Copilot Studio. In the companion lab, reuse a skill in Agent Builder and ground the agent in a supplied report.
Hands-on Lab
