Cloudflare OS is an operating system for AI productivity. It features an agent chat UI where users can ask agents to do tasks, sandboxed application development, and a security framework that applies guardrails to both agents and apps. Developed to be used internally at Cloudflare, Cloudflare OS is now open source so others can copy it and customize it for their own companies. The basic user experience of Cloudflare OS is something like an online office suite, but each file is potentially its own custom application written by AI to serve exactly your needs.

An advanced agentic harness for production-sized agents is proposed here, emphasizing the need for well-structured operations through components like typed tools, directed acyclic graphs (DAGs), tiered memory, and verification hierarchies to create a reliable system capable of planning, acting, recovering, and self-evaluating. This architecture uses the composition of small, testable primitives to improve efficiency and performance while making sure the system remains extensible and adaptable.
