The brief the agent was handed

What it was asked for.

Audience

Homeowners with solar panels considering a battery

The pitch

Housecell is a modular home battery you can start with one 5kWh unit and stack to four, with an app that shows the actual payback in pounds. The page is a bento grid where every tile is one number the buyer is trying to work out.

Sections it decided on

  1. Bento hero: payback tile, capacity tile, blackout tile
  2. Sizing: how many units your house actually needs
  3. Blackout behaviour and what stays on
  4. Tariff arbitrage: charging cheap, using expensive
  5. Installation: one day, MCS certified
  6. Warranty and the cycle guarantee
  7. Real numbers from four installed homes
  8. Book a survey

The run

Fifty of these. About one developer day.

Same toolchain, fifty different briefs, no templates. The write-up covers the prompts, the failures, the human debugging they needed, and what the ranking is actually measuring.

Fictional demo

Every one of these fifty businesses is invented. The pages, and all the text, statistics, prices, reviews, people and images on them, were generated by AI as a design demonstration. Nothing here is a real offer, a real endorsement, or professional advice. Full notice
