Methods for transferring control and context between specialized agents in multi-agent systems

Core Idea:

Agent handoff mechanisms enable coordinated transitions between specialized AI agents, allowing complex tasks to be divided among different experts while maintaining contextual continuity and a seamless user experience.

Key Principles:

1. Context Preservation:
   • Transferring relevant conversation history and state information between agents
2. Intent Recognition:
   • Identifying when a request falls outside current agent's expertise and requires handoff
3. Explicit Transition:
   • Clearly communicating to users when a transition between specialists is occurring
4. Architectural Support:
   • Implementation varies based on whether using Supervisor or Swarm architecture

Why It Matters:

• Expertise Utilization:
  • Allows each specialized agent to focus on its core competencies
• User Experience Continuity:
  • Creates seamless transitions without requiring users to repeat information
• System Scalability:
  • Enables adding new specialized agents without redesigning the entire system
• Model Performance Optimization:
  • Helps smaller models perform better by limiting their scope of responsibility

How to Implement:

1. Define Transfer Tools:
   • Create specific tools that agents can call to initiate handoffs
2. Implement Context Sharing:
   • Establish mechanisms to pass relevant history and state information
3. Design Transition Communication:
   • Create clear messages for users when transitions occur
4. Set Up Agent Registry:
   • Maintain a registry of available specialized agents and their capabilities

Example:

• Scenario:

  • Travel booking system with flight and hotel specialists

• Application:

Example transfer tool definition

transfer_to_hotel_agent = Tool(
name="transfer_to_hotel_assistant",
description="Transfer the conversation to the hotel booking specialist",
func=lambda _: "Transferring to hotel booking specialist...",
)

In flight agent's tools list

flight_agent_tools = [search_flights, book_flight, transfer_to_hotel_agent]
```

• Result:
  • When user asks "Now I need a hotel," flight agent recognizes this is outside its domain and calls the transfer tool, passing control to the hotel specialist
