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.

This sample does not require any input to run.

       [ START ]
           |
           v
[generate_fruit_agent]
           |
           v
[generate_benefit_agent]

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)],
   )
