Cairn 3.0: multi-agent handoffs
Agents can now hand work to other agents with full context, shared traces and approval gates at every boundary.
Cairn 3.0 introduces handoffs: one agent can pass a run to another — triage to billing, research to follow-up — with the full context and a single, continuous trace.
What’s new
Handoff step with typed context passed between agents
One trace across every agent involved in a run
Approval gates at handoff boundaries
Per-agent permissions remain enforced after handoff
Getting started
Add a Handoff step in the workflow builder and choose the receiving agent. Existing agents work without changes.
