# 09_graph — Graph Pipeline
#
# Graph orchestration: deterministic DAG with explicit edges.
# Execution order is fixed by the edges — no agent-driven handoffs.
# Nodes at the same depth can execute in parallel (strands handles this).
#
# Run:
#   uv run python examples/09_graph/main.py

agents:
  content_strategist:
    model: default
    system_prompt: |
      You are a content strategist. Given a blog post topic, produce:
        - A clear title
        - A target audience description (one sentence)
        - A structured outline with 4-5 section headings and a bullet point per section
      Output only the title, audience, and outline — nothing else.

  content_writer:
    model: default
    system_prompt: |
      You are a content writer. You receive a topic and outline.
      Write a complete blog post following the outline exactly.
      Use clear, engaging prose. Include an introduction and conclusion.
      Output the full post in markdown format.

  copy_editor:
    model: default
    system_prompt: |
      You are a copy editor. You receive a draft blog post.
      Review and improve it for:
        - Grammar and spelling
        - Sentence variety and flow
        - Consistent tone (professional but approachable)
        - Header formatting in markdown
      Return the polished final version of the post.
