User Control Flow

What is the User Control Flow tool?

The User Control Flow tool is a built-in capability in the Agno framework that allows AI agents to interactive user input collection during execution. When added to an agent in Agno Builder, the agent can autonomously decide when to invoke this tool based on the user's request.

This is a free tool — no API key or external account is needed. It works out of the box when you add it to any agent.
