Anthropic Launched Dynamic Workflows. Let's Build a Tiny Fan-Out Budget in TypeScript.
An agent used to be one loop. Now it can write a program that runs a few hundred more. On October 9, 2026, Anthropic added dynamic workflows to Claude Managed Agents , in beta under the managed-agents-2026-04-01 header.

Anthropic has introduced dynamic workflows to Claude Managed Agents, allowing a program to run multiple agents in phases and combine their results. This feature is currently in beta and can be enabled by adding a specific field to the agent configuration. The agent writes the workflow, and the server runs it in the background as a workflow run.
The workflow run can have limits on the number of concurrent workers, total workers, dollars, and tokens. Anthropic's workflow runs documentation specifies that 64 threads can work simultaneously in one run, and the total number of agents over a run's whole life is limited to 1,000.
