ADK Workflow Sequence Sample

Overview

This sample demonstrates how to create a simple sequential workflow with ADK Workflows.

It connects two LLM agents in a chain. The first agent (generate_fruit_agent) is instructed to return the name of a random fruit. The output of this agent becomes the input for the second agent (generate_benefit_agent), which then tells a health benefit about that specific fruit.

In a sequence, the execution flows unconditionally from one node to the next in the order they are defined.

Sample Inputs

This sample does not require any input to run.

How To

1. Define the agents or functions that will make up the steps in your sequence.

   generate_fruit_agent = Agent(...)
   generate_benefit_agent = Agent(...)
   

2. Pass a tuple of three or more elements to edges to define an unconditional sequence starting from the first element and passing through each subsequent node in order.

   Workflow(
       name="root_agent",
       edges=[("START", generate_fruit_agent, generate_benefit_agent)],
   )
