DA-Forge: Autonomous Developer Agent for n8n Workflow Generation

About the Project

DA-Forge is a revolutionary multi-agent AI system that transforms natural language descriptions into production-ready n8n workflows automatically. Built for the Agent Development Kit Hackathon with Google Cloud, this project represents the cutting edge of autonomous development agents.

What Inspired Us

The inspiration came from watching developers spend countless hours manually creating complex automation workflows in n8n. We realized that with the power of modern AI agents and Google's ADK framework, we could create an autonomous system that understands human intent and translates it directly into functional automation workflows.

The Vision: "What if you could just describe what you want automated, and an AI agent would build the entire workflow for you?"

The Problem We Solved

• Manual Workflow Creation: Setting up n8n workflows requires deep technical knowledge
• Time-Consuming Process: Complex workflows can take hours or days to design and implement
• Technical Barriers: Non-technical users struggle with workflow automation tools
• Repetitive Tasks: Developers recreate similar patterns repeatedly

Our Solution

DA-Forge introduces a zero-code approach to workflow automation:

1. Natural Language Input → User describes their automation needs in plain English
2. AI-Powered Planning → Multi-agent system analyzes and plans the optimal workflow structure
3. Automatic Generation → Advanced agents create production-ready n8n JSON workflows
4. One-Click Deployment → Seamless integration with n8n for immediate workflow activation

How We Built It

Architecture Overview

Our system follows Google's Agent Development Kit (ADK) architecture with a sophisticated multi-agent approach:

Input Agent → Planner Agent → Generator Agent → Deploy Agent

Core Components

1. Multi-Agent Orchestration

class DAForgeTeam(AgentTeam):
    def __init__(self):
        self.input_agent = InputAgent()
        self.planner_agent = PlannerAgent() 
        self.workflow_generator = WorkflowGenerator()
        self.deploy_tool = DeployTool()

2. Intelligent Planning System

The planner agent uses advanced prompt engineering with Claude/OpenRouter to:

• Analyze user requirements
• Identify optimal n8n node combinations
• Plan data flow and error handling
• Generate comprehensive workflow specifications

3. Dynamic Workflow Generation

Our generator creates production-ready n8n JSON with:

• Proper node connections and configurations
• Error handling and retry logic
• Environment-specific adaptations
• Optimized execution paths

4. Seamless User Experience

Built with Streamlit for an intuitive interface featuring:

• Real-time progress tracking
• Step-by-step visualization
• One-click JSON download
• Beautiful, responsive design

Technical Implementation

Multi-Agent Coordination

async def execute_workflow_generation(self, user_input: str):
    # Phase 1: Input Processing
    processed_input = await self.input_agent.process(user_input)

    # Phase 2: Intelligent Planning
    workflow_plan = await self.planner_agent.create_plan(processed_input)

    # Phase 3: JSON Generation
    workflow_json = await self.generator.build_workflow(workflow_plan)

    # Phase 4: Deployment Ready
    return self.deploy_tool.prepare_deployment(workflow_json)

Advanced Prompt Engineering

We developed sophisticated prompts that enable the AI to understand complex automation requirements and translate them into precise n8n configurations.

Memory Management

Implemented short-term memory for context retention across agent interactions:

class ShortTermMemory:
    def store_context(self, key: str, value: Any)
    def retrieve_context(self, key: str) -> Any
    def update_workflow_state(self, state: Dict)
