Labspace - DevDuck Multi-Agent Systems

This Labspace provides an overview of the DevDuck Multi-Agent System, a secure AI coding agent for Node.js programming assistance built with Google Agent Development Kit (ADK). The system features a coordinating agent (DevDuck) that manages two specialized sub-agents (Local Agent and Cerebras) for different programming tasks.

Learning objectives

This Labspace will teach you:

Multi-agent coordination and intelligent routing between specialized AI agents
Google Agent Development Kit (ADK) architecture and implementation
Agent specialization patterns (coordination vs execution vs analysis)
Docker Compose orchestration for multi-agent systems
Agent-to-agent communication and task delegation
Debugging agent decision-making through trace visualization

System Architecture

Three-Agent System:

DevDuck Agent: Main coordinator using Qwen3 model
Local Agent: General development tasks using Qwen2.5 model
Cerebras Agent: Complex problem-solving using Llama-4 Scout via Cerebras API
