nodes:
  - id: analyze
    type: agent
    name: "Risk Analysis"
    purpose: "Analyze the code change and output a risk score from 0 to 10. Just output a single number."
    runtime:
      provider: anthropic
      model: claude-sonnet-4-20250514
      system_prompt: "You analyze code changes for risk. Output ONLY a number from 0-10. 0=trivial, 10=extremely risky."

    outputs: [risk_score]

  - id: fast_track
    type: agent
    name: "Fast-Track Approval"
    purpose: "Auto-approve low-risk changes with a brief comment."
    inputs: [risk_score]
    runtime:
      provider: anthropic

  - id: deep_review
    type: agent
    name: "Deep Review"
    purpose: "Perform thorough code review for high-risk changes."

  - id: human_review
    type: human
    name: "Human Decision"
    purpose: "Human reviews the AI findings and makes final decision."
    inputs: [review_findings]

  - id: error_handler
    type: agent
    name: "Error Recovery"
    purpose: "Handle any failures in the review pipeline."
    runtime:

edges:
  # Risk analysis routes to different paths
  - from: analyze
    to: fast_track
    mode: conditional
    condition: "risk_score < 5"
    label: "Low risk → fast track"

  - from: analyze
    to: deep_review
    mode: conditional
    condition: "risk_score >= 5"
    label: "High risk → deep review"

  # Deep review needs human sign-off
  - from: deep_review
    to: human_review
    mode: sequential

  # Fallback: if analysis fails, route to error handler
  - from: analyze
    to: error_handler
    mode: fallback
