3.2. Building Agent Logic in Copilot Studio

With the right agent type selected, the architect must design the internal logic that drives agent behavior. Copilot Studio provides three primary mechanisms for building agent logic: topics (conversational routing), agent flows (multi-step orchestration), and prompt actions (AI-powered operations). Understanding when to use each — and how they interact — is a core exam skill.

Think of agent logic as three layers: topics handle what the agent responds to (routing), agent flows handle how it processes multi-step tasks (orchestration), and prompt actions handle what AI does at each step (generation). Understanding which layer handles which concern is key to clean agent design.

⚠️ Common Misconception: Copilot Studio topics work like traditional chatbot scripted dialogs. In reality, topics use generative orchestration to dynamically interpret intent, with fallback topics handling unrecognized inputs through AI reasoning rather than keyword matching.
