Recreated prompt

The source didn't share its exact prompt, so we wrote one from what it describes. The result shown is the source's, not ours.

What the prompt labels mean

The person didn't share their exact words, so we wrote this from what they described. We haven't tested it, and they didn't use this exact version.

Plan a week of fitness-focused meals for a household with kids ages 20, 18 and 14. Stay under a $300 grocery budget. Include dinner themes such as fish fry and taco night. Compare prices and build carts at Hy-Vee and Fareway using this week's ads. Pause for me to verify logins and approve items before checkout.

Try this in:

ChatGPT Used in source Gemini Grok Claude

Sends the Recreated prompt shown above. ChatGPT and Grok open with it filled in, and ChatGPT may send it straight away. Gemini and Claude open empty, so we copy the prompt for you to paste. Every button also copies it.

Opens in a new tab. We don't see what you send.

Optional stronger version

Our rewrite with extra checks. The poster didn't test it.

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Have an agent plan a week of meals and fill grocery carts at two stores without going over budget.

Questions to ask me first:
- Who is eating, and what are the health or fitness goals?
- What is the hard grocery budget?
- Which two stores and weekly ads should the agent use?

Inputs (fill in or confirm):
- Household and goals: [PEOPLE / GOALS]
- Budget: [AMOUNT]
- Dinner themes: [LIST]
- Stores and ads: [STORE1 / STORE2]

Rules:
- Stay under the budget I set.
- Build separate carts per store and use weekly ads.
- Pause for login verification and item approval before checkout.
- Prefer overlapping ingredients and kid-acceptable meals.

Checkpoint: Show the meal plan and estimated totals before building live carts.

If you get stuck: If a store blocks the agent, finish the list for manual add-to-cart and say so clearly.

Verify before you finish: Sum both carts against the budget and list any items I still need to approve.

Output: Meal plan with recipes, snack/lunch ideas, and two store carts with running totals.

Done when: I can approve or edit carts and check out under budget.

Outcome

Aaron Maurer, feeding three kids (ages 20, 18 and 14) with a fitness-focused meal plan and a budget under $300, used ChatGPT's agent feature to plan, price-compare and shop for a week of meals. The agent created a full meal plan with recipes, suggested healthy snacks and lunches, built shopping carts in Hy-Vee and Fareway while accounting for weekly ads, and left Maurer in control to verify logins and adjust items. Maurer recorded the run on YouTube and noted the project wasn't perfect, with lessons and frustrations saved for later posts, but called it a powerful new workflow.
