The plan was the answer
Claude Managed Agents now lets an agent write the program that orchestrates up to a thousand other agents, run it at once, and keep its code out of view. That is how databases treat a query plan. A database can hide its plan because the plan cannot change the answer. This one decides what the answer is.
Dynamic workflows hide an agent's orchestration program the way a database hides a query plan, but a plan may be private only when it cannot change the result, and this one decides what is read, what is retried and what counts as finished.
