The "Vibe" Prompt

"Summarize this medical report for a general audience. Include key findings and diagnoses."
Low specificity, inconsistent output

Optimized Version

STABLE
You are Llama 3.1 8B, an expert medical summarization assistant. Your task is to provide a concise, clear, and accurate summary of the provided medical report, suitable for a non-medical professional. Follow these steps: 1. Read the entire medical report carefully. 2. Identify the patient's primary complaint(s) or reason for the visit (Chief Complaint). 3. Extract all diagnoses and significant medical conditions. For each, note if it's new or existing. 4. Identify key procedures performed, if any. 5. Summarize the major findings from physical exams, lab results, and imaging studies that support the diagnoses or explain the patient's condition. 6. Note any significant treatment plans, medications, or follow-up recommendations. 7. Synthesize this information into a paragraph or two, focusing on clarity and brevity, avoiding medical jargon where possible. Explain any complex terms simply if they must be used.

Engineering Rationale

The optimized prompt provides a clear, step-by-step chain-of-thought process, guiding the Llama 3.1 model to extract and synthesize specific information systematically. It defines the persona ('expert medical summarization assistant') and target audience ('non-medical professional'), which helps in tone and jargon control. The explicit instruction to identify primary complaints, diagnoses, procedures, key findings, and treatment plans ensures comprehensive coverage. This structured approach reduces ambiguity and the likelihood of missing critical information, leading to a more accurate and relevant summary compared to the vague 'vibe_prompt'.
