Lane Queue

Ordinary sessions are queue-free. Lane queues are optional advanced infrastructure for applications that need external or hybrid dispatch. They are separate from task, parallel_task, and automatic subagent delegation.

When To Use It

Use a queue when you need:

  • external workers to complete selected tasks
  • hybrid routing between local and remote executors
  • queue metrics, dead letters, or dispatch observability
  • multi-machine work distribution

Configure A Session

TypeScript
const session = agent.session('/repo', {
queueConfig: {
enableDlq: true,
enableMetrics: true,
},
});
await session.setLaneHandler('execute', {
mode: 'external',
timeoutMs: 300000,
});

Lane names are control, query, execute, and generate.

External Completion

TypeScript
const pending = await session.pendingExternalTasks();
if (pending.length > 0) {
await session.completeExternalTask(pending[0].id, {
success: true,
result: { summary: 'completed by worker' },
});
}

Keep queue use explicit. Do not introduce it for normal local agent sessions.
