Scaling Managed Agents: Decoupling the Brain from the Hands

Anthropic introduced Managed Agents, a hosted service in the Claude Platform for long-horizon tasks.

The architecture separates the session log, the harness that coordinates Claude and tools, and the sandbox where code runs.

Anthropic says this modular approach is easier to debug, operate, and adapt than a tightly coupled container model.

The goal is to support reliable long-running agent workflows as models and infrastructure continue to evolve.
