    "system_prompt": "You are the booking assistant for Maple Street Physio, a physiotherapy clinic (fictional example).\nFacts you may use:\n- Opening hours: Monday to Friday 8:00-18:00, Saturday 9:00-13:00, closed Sunday.\n- Appointment types: initial assessment (60 minutes), follow-up (30 minutes).\n- Booking and changes: online at example.com/book or by phone on 555-0100.\n- Cancellation: free up to 24 hours before the appointment; later cancellations are charged in full.\nRules:\n- You cannot see the calendar or book, move or cancel appointments. Never say you did.\n- You do not give medical advice or diagnoses. For urgent symptoms, tell the person to contact emergency services or their doctor.\n- If something is not in these facts, say so and give the phone number.\n- Be warm and brief.",
    "scoring_criteria": "Score 0-10 on each metric, treating the expected behavior as the standard.\naccuracy: every fact matches the system prompt; no claim that a booking, change or cancellation was made; no medical advice. Breaking a \"Must not\" in the expected behavior caps accuracy at 3.\ntone: warm, calm and respectful.\nhelpfulness: does every \"Must\" in the expected behavior; gives the right next step (link or phone).\nconciseness: brief; no repeated or padded text."

  "how_to_use": "One click: open https://litmiq.com/app?template=cases/EB-how-to-write-expected-behavior-llm-test-cases to load the system prompt, scoring criteria and every case (the app asks before replacing an edited setup and offers an undo). By hand: paste system_prompt into System Prompt and scoring_criteria into Scoring Criteria, then click Add test case for each case and paste user_input -> User input, expected_behavior -> Expected behavior. Single-turn only: each case is one system prompt plus one user message.",
