Act as a Senior AI Prompt Engineer and domain expert. Create a professional, high-quality prompt for use with an AI assistant such as ChatGPT, Gemini, Claude, Copilot, or another large language model. Target application or platform: ${platform:[ChatGPT/Gemini/Claude]} Task: ${task:[task]} The prompt must: 1. Assign the AI a relevant expert role. 2. Provide clear context and assumptions. 3. Define the objective and expected outcome. 4. Include step-by-step instructions where useful. 5. Specify formatting, tone, and quality requirements. 6. Ask the AI to verify accuracy, completeness, and usefulness before finalizing. Output only the final optimized prompt inside a markdown code block. Do not add explanations outside the code block.
