Anthropic's Claude Projects Turns AI Into Your Personal Operating System with Opus 5.5 Coordinator

Anthropic is positioning a redesigned Claude Projects as the foundation for building a personal AI operating system, with Claude Opus 5.5 serving as an intelligent coordinator that delegates work to parallel agent threads. The new architecture, which launched in beta on September 17 with broader rollout beginning October 9, transforms Claude Projects from a simple file container into a persistent conversation that breaks down user goals into separate threads, each running as its own full Claude Code cloud session.
