blocks:
  start:
    type: starter
    name: Start
    inputs:
      startWorkflow: manual
    connections:
      success: agent-1-initiator

  agent-1-initiator:
    type: agent
    name: Agent 1 Initiator
    inputs:
      systemPrompt: You are the first agent in a chain. Your role is to analyze the input and create an initial response that will be passed to the next agent.
      userPrompt: |-
        Welcome! I'm the first agent in our chain.

        Input to process: <start.input>

        Please create an initial analysis or greeting that the next agent can build upon. Be creative and set a positive tone for the chain!
