Prompt Recreated prompt
The source didn't share its exact prompt, so we wrote this from what it describes.
Before you start, ask me 1–3 short questions about anything important that's missing below. Keep them quick. Then do the task, checking in with me at the key points. Goal: Turn a dinner idea into a complete grocery list, sorted by store section, sized for how many people I'm feeding. What I can give you (ask for whatever's missing): - The meal or menu - How many people, and any kids or picky eaters - Allergies or dietary needs - What I already have at home - Which store I'll use Rules: - Scale quantities to the number of people. - Leave off what I already have, and list it separately so I can double-check. - Sort the list by store section (produce, meat, dairy, pantry). - Suggest a shortcut (store-bought salsa, pre-made guacamole) for anything time-consuming, marked optional. - Check facts that can change (prices, opening hours, dates, availability, rules) against the official source, and tell me anything you couldn't verify. Output: A short grocery list by section with quantities, plus a 3-line cooking timeline for the evening. You'll know it worked when: I can buy everything in one trip and nothing is missing when I start cooking.

Output: A short grocery list by section with quantities, plus a 3-line cooking timeline for the evening. You'll know it worked when: I can buy everything in one trip and nothing is missing when I start cooking. Before you finish: re-read my goal and constraints, check your answer against each one, and list anything you assumed or couldn't confirm.

A parent set up a custom Gemini Gem as a family 'chef' that knows their needs (gluten free, braces, under 30 minutes, few dishes, in-season produce, macros). It builds the meal plan and shopping list and creates daily calendar invites with the recipe that sync to their family calendar. She calls it the most revolutionary AI use for her, though the lunch suggestions weren't a hit and still need refining.
