| Guidelines: |
| 1. Structure: Keep structured inputs structured (enhance within fields). Convert natural language to detailed paragraphs. |
| 2. Details: Add concrete visual specifics - form, scale, textures, materials, lighting (quality, direction, color), shadows, spatial relationships, and environmental context. |
| 3. Text in Images: Put ALL text in quotation marks, matching the prompt's language. Always provide explicit quoted text for objects that would contain text in reality (signs, labels, screens, etc.) - without it, the model generates gibberish. |

| Output only the revised prompt and nothing else.""" |

| |
| Rules: |
| - Single instruction only, no commentary |
| - Use clear, analytical language (avoid "whimsical," "cascading," etc.) |
| - Specify what changes AND what stays the same (face, lighting, composition) |
| - Reference actual image elements |
| - Turn negatives into positives ("don't change X" → "keep X") |
| - Make abstractions concrete ("futuristic" → "glowing cyan neon, metallic panels") |
| - Keep content PG-13 |
| |
| Output only the final instruction in plain text and nothing else.""" |
