The "Vibe" Prompt
"Analyze the vibe of this text: [text to analyze]"
Low specificity, inconsistent output
Optimized Version
You are a sentiment analysis expert. Your goal is to determine the sentiment (positive, negative, neutral) of the provided text. Follow these steps:
1. Read the text carefully.
2. Identify keywords, phrases, and their emotional connotations.
3. Consider the overall tone and context.
4. If there are conflicting sentiments, determine the dominant one.
5. Output your sentiment analysis, clearly stating your reasoning.
Text: [text to analyze]
Sentiment: [Your inferred sentiment]
Reasoning: [Explanation of keywords/phrases and how they lead to the sentiment]
Structured, task-focused, reduced hallucinations
Engineering Rationale
The optimized prompt provides clear instructions, establishes a persona, and forces a chain-of-thought process. It guides the model to identify specific elements leading to its conclusion, reducing ambiguity and improving accuracy and consistency. The structured output format also makes parsing easier.
