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.
