# Example 14: Composition Blocks
# Demonstrates do: blocks, block definitions, and inline sequences

# Define reusable agents
agent researcher:
  model: sonnet

agent writer:
  model: opus
  prompt: "You are a skilled technical writer"

agent reviewer:
  model: sonnet
  prompt: "You are a careful code and document reviewer"

# Define a reusable research block
block research-phase:
  session: researcher

  session: researcher
    prompt: "Analyze key findings"

# Define a reusable writing block
block writing-phase:
  session: writer
    prompt: "Write initial draft"
  session: writer
    prompt: "Polish and refine the draft"

# Define a review block
block review-cycle:
  session: reviewer
    prompt: "Review for accuracy"
  session: reviewer
    prompt: "Review for clarity"

# Main workflow using blocks
let research = do research-phase

let document = do writing-phase

do review-cycle

# Use anonymous do block for final steps
do:
  session "Incorporate review feedback"
  session "Prepare final version"
