Requirement

Implementation method

Let the agent decide when to run a tool based on user input.

Enable generative orchestration.

Run a specific agent flow at a defined step in a topic.

Add a tool node.

Use a connector action to retrieve data during a conversation.

Add a tool node.

Comprehensive and Detailed Explanation From [Microsoft AB-620 Study Guide]

Generative orchestration is appropriate when the agent must independently determine whether a tool is relevant to the user’s request. Copilot Studio evaluates the user’s message, conversation context, and the tool’s name, description, inputs, and outputs before deciding whether to invoke it. Microsoft documentation confirms that generative orchestration allows an agent to choose tools based on their descriptions and the current user query.

When an operation must occur at a predetermined point in an authored topic, the operation should instead be inserted explicitly by using an Add a tool node. Selecting an agent flow from that node ensures that the flow executes at that exact position in the topic rather than being selected autonomously by the orchestrator.

The same node type is used when calling a connector action. From the topic canvas, the author selects Add a tool , chooses Connector , and then selects and configures the required connector operation. Adaptive Cards present interactive information, while Question nodes collect user input; neither directly invokes flows or connectors.
