"content": "=You are tasked with generating {{ $json.number_ads }} image description variants for ad creatives based on a specific creative methodology.\n\nINPUT PARAMETERS:\n- Company Name: {{ $json.company_name }}\n- Number of Ads to Generate: {{ $json.number_ads }}\n- Creative Recipe: {{ $json.ad_creative_recipe }}\n- User Instructions: {{ $json.user_comments }}\n- Copy writting inspiration: {{ $json['Provide an example of copy writting for inspiration'] }}\n\nORIGINAL IMAGE DESCRIPTION:\n{{ $json.image_description }}\n\nCREATIVE METHODOLOGY GUIDE:\n\n**IF \"The metaphor bake\" is selected:**\n- Turn the key message into a visual metaphor or analogy\n- Use figurative imagery (objects, scenes, symbols, idioms, cultural references)\n- The visual should communicate the message clearly without needing extra copy\n- Make it instantly understandable and human, not overly conceptual\n- Ensure the product/brand connects logically back to the metaphor\n- Examples: Running after money on a fishing rod (chasing gains), board game representing guesswork\n\n**IF \"The pointer platter\" is selected:**\n- Show the product UI or mockup clearly\n- Feature 3-4 visual pointers/callouts highlighting key features or capabilities\n- Keep labels short (1-3 words) and position them around the UI with arrows or pills\n- Make the value proposition unmissable at a glance\n- Ensure all text elements stay readable and not cluttered\n- Focus on product education and clarity\n\n**IF \"The comparison combo\" is selected:**\n- Show a clear Before/After, Us vs. Them, With vs. Without, or Old Way vs. New Way comparison\n- Split the visual into two contrasting sides\n- Use visual or textual elements to show the \"hard way\" vs. the \"better way\"\n- Make the contrast unmistakable even without reading text\n- Use color, structure, or layout to emphasize the difference\n- Show transformation or improvement that the product creates\n\n**IF NO recipe is selected or field is empty:**\n- Keep the style and approach similar to the original image description\n- Maintain the same visual language and messaging approach\n- Focus on clarity and brand consistency\n\nTASK:\n1. First, determine which creative recipe applies (or if none selected)\n2. Modify the original image description according to:\n - The selected creative recipe methodology\n - The User Instructions provided\n - The ORIGINAL IMAGE DESCRIPTION\n - Copy writting must be based on the company and copy writting instruccions. not based on the image provided\n3. Generate {{ $json.number_ads }} additional variants with modifications to:\n - Color schemes and backgrounds\n - Visual styling and composition\n - Copy/text positioning and wording\n - Character poses, UI layouts, or comparison elements\n - Creative execution details\n\nRULES:\n- Keep the company name \"{{ $json.company_name }}\" consistent across all variants\n- Make sure copy writting is related to the company and inspiration provided in {{ $json['Provide an example of copy writting for inspiration'] }}\n- Apply BOTH the creative recipe methodology AND user instructions to ALL variants\n- Each variant must follow the same recipe but with distinct visual execution\n- Ensure descriptions are detailed enough for image generation\n- All variants should feel cohesive as part of the same ad campaign\n\nOUTPUT FORMAT (strict JSON):\n{\"variants\":[\"First variant following the recipe + user instructions\", \"Second variant with color/style changes\", \"Third variant with different composition\", \"Fourth variant with alternative styling\", \"Fifth variant with unique creative twist\"]}\n\n---\n\nEXAMPLE 1 - \"The metaphor bake\":\n{\"variants\":[\"A cheerful cartoon character with long hair and a beard running behind a dollar tied to a rod that comes from his back.
