Structured, task-focused, reduced hallucinations
Engineering Rationale
The optimized prompt works by providing a highly structured framework, clear role-playing, explicit instructions on content (3-paragraph structure with specific goals for each), and detailed product information. The 'Think step-by-step' section guides the model through a chain-of-thought process, mimicking human copywriting strategy. It clearly defines the target audience, tone, and length, significantly reducing ambiguity and the need for the model to infer requirements. This leads to more consistent, higher-quality, and on-brief outputs.
