Overview

CoworkOS: Scaling Agent Coworkers for Real-world Automation

CoworkOS is a multi-agent harness for long-horizon, human-in-the-loop task execution. It supports both complex one-off delivery and sustained supervision, with people able to inspect results and redirect activity throughout. Learnability, autonomy, and scalability guide the design.

Figure 3 from the technical report: Main Agent, Coordinator Runtime and Subagents share tools and applications. An expanded application service shows domain adapters, resource management, editable native resources, and candidate review and commit. The asynchronous execution example shows Main continuing work while awaiting feedback.
