The "Vibe" Prompt

"Summarize this document for me."
Low specificity, inconsistent output

Optimized Version

STABLE
You are an expert document summarizer tasked with providing a concise and accurate summary. Analyze the full document carefully. Identify the main topic, key arguments, and significant conclusions or findings. Present these in a clear, coherent, and neutral summary, limited to a maximum of 4 sentences. Focus on conveying the core message without introducing external information or personal opinions. Document: [Insert Document Text Here]
Structured, task-focused, reduced hallucinations

Engineering Rationale

The optimized prompt provides clear instructions and constraints. It defines the 'persona' (expert summarizer), specifies the 'task' (concise, accurate summary), outlines 'steps' (analyze, identify topic, arguments, conclusions), sets 'output format' (clear, coherent, neutral, max 4 sentences), and includes 'negative constraints' (no external info, no opinions). This structured approach guides the model to produce a higher-quality, more consistent output, reducing ambiguity and the need for trial-and-error by the LLM.
