Ready-to-paste prompt
Create a product specification for a new smartwatch by running `npx ts-node index.ts --input '{"name": "SmartWatch", "description": "A new smartwatch with health tracking features"}'`
Heads up: Make sure you have Node.js and TypeScript installed on your system, and that you have the `ts-node` package installed globally by running `npm install -g ts-node`
