A hierarchical multi-agent design pattern with a central coordinator that delegates tasks to specialized sub-agents

Core Idea:

Supervisor Architecture implements a multi-agent system where a central "supervisor" agent manages user interactions and delegates specialized tasks to sub-agents, which perform their work and return results to the supervisor rather than interacting directly with the user.

Key Principles:

1. Centralized User Interaction:
   • The supervisor agent is the sole point of contact for the user
2. Task Delegation:
   • Supervisor analyzes user requests and assigns appropriate sub-agents to handle specialized tasks
3. Result Aggregation:
   • Sub-agents return their outputs to the supervisor, which integrates results before responding to the user
4. Fixed Entry Point:
   • The supervisor is always the starting point for any interaction, creating consistency

Why It Matters:

• Unified User Experience:
  • Provides a consistent interface as users always interact with the same agent
• Simplified Orchestration:
  • Clear hierarchy prevents coordination problems between multiple agents
• Quality Control:
  • Supervisor can verify and refine sub-agent responses before presenting to the user
• Efficient Resource Allocation:
  • Only relevant sub-agents are activated based on the specific user request

How to Implement:

1. Define Supervisor Agent:
   • Create a central agent with routing capabilities and a comprehensive understanding of all sub-agents
2. Create Specialized Sub-agents:
   • Develop focused agents with domain-specific tools and knowledge
3. Implement Handoff Mechanisms:
   • Set up transfer tools from supervisor to sub-agents and back
4. Configure Result Processing:
   • Have the supervisor process, verify, and integrate results from sub-agents

Example:

• Scenario:
  • Research assistant that can perform calculations and web searches
• Application:
  • User asks question → Supervisor determines question requires research
  • Supervisor delegates to research sub-agent → Research agent performs web search
  • Research agent returns information to supervisor → Supervisor summarizes and presents to user
• Result:
  • User receives a cohesive response while specialized work is handled by appropriate sub-agents
