Hierarchical Agent Systems
CEO agent → manager agents → worker agents — like a corporate org chart.
3 hours1 prereqs
For complex tasks, the multi-level version of orchestrator-worker:
- Level 0 (CEO): takes the user's top-level goal
- Level 1 (Managers): splits into sub-domains (research, code, write)
- Level 2 (Workers): executes atomic tasks
Each level has its own system prompt, tool subset, context. Information flows up summarized.
Pro: scalability — projects with 100+ subtasks. Con: complex debugging, high cost.
CrewAI supports hierarchical teams pattern.
