Orchestration means graphs, supervisors, workflows, retries, and human approval — mapped to real HazelJS primitives without inventing a handoff API.
Agent orchestration is how you coordinate steps, agents, state, retries, timeouts, and human approval so work completes reliably.
In HazelJS, orchestration is not a single class named “Orchestrator.” It is a set of real primitives:
- AgentGraph and supervisor patterns for multi-step / multi-agent routing
@Delegatefor agent-to-agent delegation- A2A for interoperable agent protocols
@hazeljs/flowfor durable WAIT/resume business workflows@hazeljs/queuewhen you need BullMQ-style job queues- Durable runs + HITL for crash-safe approval gates
There is no first-class API named handoff in @hazeljs/agent. Prefer the primitives above.
Minimal runtime loop
await runtime.execute('support-agent', goal, {
loop: { maxIterations: 8, successScore: 95 },
});
The confidence loop stages are plan → execute → critique → validate (optional observe).
