A week of vegan dinners, planned by agents.

"What should we eat?" My partner and I could never agree.

And deciding was only the start. I wanted the shopping list written for us, with a rough price for everything at each store. I wanted the stores near us close at hand. I wanted a way to rate each dinner, and a cookbook of the ones we loved.

It began as a course exercise. In my Product Management with AI course we were asked to build one agent. I had built agents before, so I set myself a harder brief: four agents that work together on a problem from my own life.

• A plan is only useful if you can trust it. Prices change and shops differ, so Vegan Chef had to be honest about what it knows and what it estimates.
• Two people, one plan. Both of us choose, rate and shop, so nothing could get out of step.
• Agents need boundaries. Each one has a single job and stays out of the others' work.

I wrote a product brief first: the problem, the users, the job to be done, goals with a way to measure each one, what is in and out of scope, and acceptance criteria.

Then I built four AI agents, each with one job, that hand the week from one to the next.

1. 01

   Find dinners

2. 02

   Pick together

3. 03

   Plan and shop

4. 04

   Rate and keep

Here is what a week looks like from our side:

• New dinner ideas arrive without anyone searching.
• We each pick what we fancy.
• A plan for the week arrives with one shopping list. It shows the approximate price of each item across our stores, so we can see where the week is cheapest.
• The stores near us are a tap away.
• After we eat, we rate the dinners. The ones we love go into our own cookbook.

How the agents do all this stays in my kitchen.

I turned the acceptance criteria into 25 tests and tracked each one in Linear. Testing caught things I would have missed, like a gluten-free week that suggested an ingredient containing wheat. I fixed each one and tested again.

My partner used it too, and liked it. His feedback is shaping the next version.

• Make the changes from my partner's feedback and start fresh in December.
• Finish the remaining tests, including the ones that need both of us signed in.
