How to Use This Prompt
- Copy the prompt and replace the bracketed sections with your specific details
- Be as specific as possible — vague input produces vague output
- Paste into ChatGPT or Claude and review the result
- Iterate with follow-ups like 'make it shorter' or 'try a different angle'

Tips to Get Better Results
- Give context. The more background you provide, the better the AI response.
- Ask for options. Request 3 versions and pick the strongest one.
- Iterate, don't accept. The first response is rarely the best.
- Edit in your voice. AI output should be a starting point, not the final.
