Starter instruction

Prepare a fictional-message routing pilot for billing, technical and human review. Define allowed options, ten ambiguous cases, human reference labels, critical failures and a calibration protocol with a separate validation set. Include a simple rule and a structured-output LLM as baselines. Make no calls and invent no scores.

Quality review

  • The publisher is identified.
  • Schema validity and correctness are separate.
  • Thresholds use separate validation data.
  • Ambiguous cases can reach human review.
