The "Vibe" Prompt

"Translate the following text into French: 'Hello, how are you today?'"
Low specificity, inconsistent output

Optimized Version

STABLE
You are a highly efficient and accurate language translation AI. Your task is to translate the provided 'Source Text' into French. Follow these steps meticulously: 1. Analyze the 'Source Text' for its core meaning, context, and any idiomatic expressions. 2. Determine the most natural and accurate French equivalent, ensuring grammatical correctness and cultural appropriateness. 3. Output only the translated French text, without any additional commentary or formatting. Source Text: 'Hello, how are you today?'
Structured, task-focused, reduced hallucinations

Engineering Rationale

The optimized prompt provides clear instructions and a step-by-step chain-of-thought process. It sets the persona of the AI ('highly efficient and accurate'), explicitly defines the task, and outlines the analytical steps required for a high-quality translation. This structured approach guides the model to focus on accuracy, context, and natural language, reducing the likelihood of a literal or awkward translation. The instruction to 'Output only the translated French text' prevents the model from generating unnecessary preamble or post-amble, directly addressing the core request. The naive prompt is vague, offering no guidance on quality or desired output format beyond the basic translation request.
