Open Agents → Create agent. Say the job in plain language: who it helps, what a good answer looks like, and whether it chats, runs a task, or routes to other agents. The builder proposes a name, type, and instructions. You Accept when the proposal is right.
Drag a connected data source or Custom MCP into the chat, or open the catalogue to create one. The builder can place that connection in the agent. Credentials stay on the connection.
The models tray lists what your organisation has enabled. Click one to prefer it. Add more from Business Center → Models.
Tell the builder which fields the reply should contain. That contract is written into the agent instructions when you Accept.
