How It Works

ROMA operates through an elegant recursive architecture that mirrors sophisticated project management methodologies while maintaining complete computational transparency. The process begins with a parent node receiving a primary objective, which triggers the system’s intelligent decomposition phase.

The Atomizer component analyzes the incoming goal to determine whether it can be executed directly or requires further breakdown into manageable subtasks. When decomposition is necessary, the Planner takes control, strategically dividing the complex objective into smaller, more focused components while considering dependencies, resource requirements, and optimal execution sequences.

Each subtask is then assigned to specialized child nodes along with comprehensive contextual information, ensuring every agent possesses the necessary knowledge for successful execution. These child nodes, which can represent specialized tools, models, or human experts, carry out their assigned responsibilities through the Executor component.

Throughout this entire process, ROMA maintains meticulous stage tracing, creating a detailed, auditable log of every decision, action, and context transfer. This transparency enables real-time monitoring, precise debugging, and continuous optimization of agent behavior patterns.

Once child nodes complete their assigned tasks, the Aggregator component synthesizes results and passes comprehensive outcomes back to their parent nodes. This recursive process continues until the original complex goal is fully achieved, creating a complete, debuggable record of the entire problem-solving journey.
