Agent builder

The Agent builder is where you configure an autonomous agent — a worker that runs jobs, monitors processes, and takes action on your behalf.

The Agent builder is the interface you work in when you are configuring an agent. An agent is an autonomous worker with a clear job — it runs on a trigger, does its work, and reports back. Unlike an app, there is no user-facing screen; the agent operates in the background.

Layout

The Agent builder has five sticky tabs always visible at the top, plus additional tabs available via the + button. There is no Preview iframe — the chat interface is the primary way you interact with the agent during development.

The five sticky tabs

Tab	What it is
Chat	Talk to the Riff agent to configure your agent; switch between Build and Live mode
Pipeline	Visual board showing your agent's tasks and their current states
Profile	Read-only view of your agent's full configuration — instructions, knowledge, skills, tools
Triggers	The email addresses and scheduled runs that activate your agent
Activity	A log of every agent run — tools called, duration, success or error

Additional tabs (via the + button)

The same features available in the App builder are also accessible here:

Tab	What it is
Integrations	Connect to external services
Storage	Upload and manage files
Secrets	Store credentials
Access	Workspace access controls
Version History	Restore past states

The Riff agent in the Agent builder

The Chat tab is the primary building surface. The Riff agent configures your agent in response to your messages — updating its instructions, adding skills and knowledge, connecting tools. See Chat and the Riff agent.
