- Workforces
- A visual canvas connects specialist agents into a team, with AI-driven handoffs, fixed sequences or conditional logic deciding how work moves between them.
- Invent
- A built-in agent that works through a business process with you, then creates the Agents, Tools, Triggers and Workforces for it and proposes improvements after launch.
