Orchestration Model

Centralized Manager:

understand task → break down into subtasks → select agents → track progress → merge results

Each specialized agent is modeled as a tool: call, pass parameters, get result – a unified abstraction provides extensibility and heterogeneity.

Manager is a single point of failure and bottleneck: Plan-and-Act shows that a weak planner limits the entire system, therefore the strongest model and best prompt go to the manager.

Manager’s context is constrained: it holds an index of files and summaries, not the content.

Forms: sequential coordination and parallel via message bus.
