Anthropic Lets Managed Agents Build Their Own Multi-Phase Workflows
In short: Anthropic has introduced a beta option on its Claude Platform that allows a Managed Agents agent to construct its own workflow for large, multi-part jobs, such as going through hundreds of documents. Instead of handling everything in one pass, the agent splits the task into phases, delegates pieces across multiple sub-agents, and merges their output into a single result. The job is handed off to the server, which executes it asynchronously and reports progress through a stream of events.

What changed?
- 1Feature is in beta, accessed via the managed-agents-2026-04-01 beta header
- 2Enabled by configuring the agent's multiagent field as {"type": "multiagent_20261001", "workflows": {"type": "enabled"}}
- 3Agent itself authors a workflow: a program coordinating multiple sub-agents across phases and aggregating their output
- 4Execution happens asynchronously on the server, tracked as a distinct workflow run
- 5Developers steer timing by instructing the agent in its system prompt about when to launch a run
- 6Monitoring is done via workflow_run.* events delivered on the session's event stream
Why it matters
This gives developers a built-in pattern for fan-out/fan-in style processing without manually orchestrating multiple agent calls, which matters for any automation that needs to process large volumes of items reliably.
What it means for AI agents and contact centers
For teams running large-scale call analytics, QA reviews, or document processing pipelines, this beta feature could reduce the custom orchestration code needed to parallelize work across many agents and track completion status.
🧪 Worth Testing
Worth testing to see how well dynamic workflows handle large batch jobs compared to manual multi-agent orchestration, and whether the event stream provides enough visibility for production monitoring.
