How the agent did it
- He set up a dedicated grocery chat and states preferences such as no olives.
- He signed the bot's browser into Amazon and Costco.
- Scheduled tasks run the grocery ordering.
@RhysSullivan wrote that one of his personal AI benchmarks is whether a model or agent harness can automate his grocery ordering. He says Grok Bot is the first to solve it well.
He lists what makes it work. He has a dedicated chat for groceries where he can state preferences, such as no olives, and the bot remembers them over time. The bot has a browser he can sign into Amazon and Costco on, and having a real running machine he can take over to sign in is, he says, very useful. Automated tasks run the ordering on a schedule. The bot can also use his MCP tools, including one called executor, to put what to cook and when on his calendar.
He says it effectively replaces a meal-kit service like HelloFresh for him, and is a better experience, cheaper and more precise about his preferences over time.
He is also clear about the gaps. He cannot add his girlfriend to the chat. He would like an artifacts system. And he finds the bot's browser use very slow, saying another tool's Chrome plugin still wins on that, though speed matters less for a background job.
He does not give order counts or cost figures.
Who it's for: Households that reorder similar groceries every week across several stores.
