What is a Gemini prompt generator?

A Gemini prompt generator turns a plain-language goal into a structured prompt with role, context, constraints, and output format. It helps Google Gemini understand the task before it answers, so briefs come back complete, structured outputs stay valid, and multimodal requests produce usable results on the first run.
