Reverse-engineer or design a PRD for any product, feature idea, or live URL. Always starts with /grill-me to clarify scope and intent. When a URL is given, uses /gstack and Puppeteer for a full site audit. Produces a structured PRD with feature overviews and numbered workflow narratives organised by module. Saves the final document to the Desktop. Use when asked to "write a PRD", "document this product", "reverse engineer this site", or "turn this idea into a PRD".
