How it works

Runner.StartSequential chains agents into a single DrylMultiAgentRun — each agent receives the previous one's answer as its input. DrylHandoffTrace renders the chain as a timeline: the active lane wears the shared aura, the connector fills as the baton is handed on, and every lane streams its own answer. StartConcurrent fans the same prompt out to every agent instead.

Where the innovation lies: multi-agent orchestration is normally invisible plumbing. Here the whole pipeline is one observable object with a UI that makes the handoff legible — you can literally see which agent holds the work right now.

// Each step's agent receives the previous agent's answer. StartConcurrent fans out instead.
var flow = Runner.StartSequential(steps, "Write a short article about glass surfaces.");
