Dynamic Workflows for Claude Managed Agents (Public Beta)

A Claude Managed Agents agent can now write a plan that splits a big job across many agents in phases and combines the results, for developers building on the Claude Platform.

Details

A lead agent writes the workflow, a program that runs many agents in phases, and the server runs it in the background as a workflow run
Turned on per agent through its multiagent setting; you tell the agent in its system prompt when it should start a run
Each run reports progress as events on the session's event stream, so you can follow it while it works
In Anthropic's own test on a 116,000-line codebase with 70 planted bugs, a single agent found 14, 15, and 27 across three runs, while a workflow found 66 in each run
Earlier dynamic workflows ran locally inside Claude Code; this version runs on Anthropic's servers as part of Managed Agents
Public beta behind the Managed Agents beta header; Anthropic suggests starting with a scoped task because runs can use a lot of tokens
