2. Implementation in n8n

Each specialist Agent = a sub-workflow connected via Workflow Tool.

3. Architecture Patterns

Pattern Use Case Pros Cons
Supervisor General routing Flexible Supervisor needs strong reasoning
Sequential Pipeline processing Simple, reliable Inflexible
Debate Multi-angle verification Reduces hallucination High token cost
