Agent Workflow
Agent Architecture Overview
Visual representation of the decoupled agent architecture using handoff tools and message passing. Each agent operates independently and communicates through structured transfer mechanisms.
The architecture leverages LangGraph’s handoff tools where agents communicate exclusively through transfer functions like transfer_to_editor({"reason": "context"}). Each transfer includes reasoning context, preserving the complete conversation state while enabling intelligent routing decisions. This ensures fault tolerance and allows agents to make informed decisions based on prior conversation history.
State management follows a message-centric approach. Transfer messages become tool messages containing both the transfer action and the reasoning context, allowing receiving agents to understand why they were invoked.
This design pattern eliminates direct node connections in favor of message-driven handoffs. Each agent receives the full conversation context plus transfer reasoning, enabling decision-making while maintaining system modularity. The approach scales horizontally and allows for dynamic agent addition without architectural changes, making it ideal for complex multi-agent workflows.
Technical Implementation Details
Agents are fully decoupled and communicate exclusively through message passing, no direct node connections. This ensures scalable, maintainable, and fault-tolerant agent networks that can dynamically adapt to changing requirements, each with access to specific tools.
