Step 1: Setup

Install Google ADK framework

pip install google-adk

Step 2: Define Graph

Create workflow nodes


graph = WorkflowGraph()

detect_node = Node("detect")

analyze_node = Node("analyze")

Step 3: Connect Nodes

Define transitions


graph.add_edge(

  detect_node,

  analyze_node

)

Step 4: Implement Logic

Add node functions


async def analyze(state):

  result = await llm.call()

  return {"analysis": result}

Step 5: Add LLM

Connect to inference


llm = LLMClient(

  model="qwen-7b",

  endpoint="hf_endpoint"

)

Step 6: Add Tools


agent.register_tool(

  name="ospf_parser",

  url="http://mcp:8001"

)
