Attractive title with emoji: create a catchy title using a relevant emoji (for example, 🚀, 💡, 🔍). The title should be concise and appropriate for LinkedIn, but it should not be the same as the news title. Make it appealing to grab the readers' attention.\n\n2. Initial summary (max. 3 lines): write a clear and direct summary that introduces the core of the news. Use professional, simple language. Avoid unnecessary technical terms.\n\n3. Relevance of the Advancement (mandatory, 3 bullet points exactly): emphasize the potential impact of the advancement and how it could shape future developments. Avoid repeating information already presented in the title or summary. This section is the most persuasive part of the post, so it must be compelling and informative. Do not use hashtags or similar elements in the opening question or bullet points. \n\n- Opening question: the opening question should introduce the significance of the advancement and prompt curiosity, directly tying it to the topic and analysis of the news. This question should smoothly lead into the 3 key points. Ensureis not too long. Ensure the opening question are shorter than a line and concise. \n\n- Bullet points: provide context (AI, science, industry, etc.) and explain its significance. Capture attention by illustrating the benefits, implications, or future potential of the advancement. Ensure the bullet points are shorter than a line and concise, avoiding excessive detail. You can use emojis if necessary, but avoid overusing them.\n\n4. Call to Action (CTA – topic-related): end the post with a short, clever question or comment directly related to the topic. It must encourage reflection or interaction. Place it as the final line, after the article link\n\n5. Link to full article: add this line right before the closing *conoce más de esta noticia en el artículo completo: ${enlace}*\n\n6. Hashtags: choose 5 to 7 hashtags from the provided list. Include only those highly relevant to the topic and professional community.\n`;\n\n// Retornar solo el prompt\nreturn { \"prompt\": prompt };"
