Claude Managed Agents drops for autonomous work

Anthropic is shifting agent development from fragile, monolithic "pets" to stateless, scalable "cattle" by treating the agent harness as a virtualized operating system. This decoupled architecture prevents model-specific hacks from becoming technical debt while persistent session logs allow agents to recover from crashes and handle tasks spanning thousands of events. By integrating secure sandboxing and credential management, developers can focus on logic rather than infrastructure. Performance data indicates that using code as a universal orchestration language is significantly more effective than natural language for complex tool use.
