Case study

One kit.
Your product.

Every kit ships as one readable file plus a design.md written for your AI agent. Here is what that means in practice: we take Gauss — an electric-car launch site — and turn it into the launch site of a hi-fi headphone. For real, step by step.

01

Pick the kit — even if it shows a car

The brief: launch the Def One, a fictional planar flagship headphone, with a premiere-night site. Gauss is built for exactly this — a dark stage where your cursor becomes an inspection reticle, magnetised by hotspots on the product. The demo shows a grand tourer. The mechanism doesn't care what stands on the stage.

Gauss — the kit as sold: an electric car on its stage

The starting point — Gauss v1.0, as sold

02

Brief your agent with the design.md

Unzip the kit, hand index.html and design.md to your agent — Claude, Cursor, whatever you use — with a brief like this one. The design.md does the heavy lifting: its Agent Instructions tell the model what must never change (one accent, one protagonist, the cursor engine, the rest zones), so the adaptation stays on rails.

Here are index.html and design.md from the Gauss kit.
Adapt it to launch the Def One, a planar flagship headphone:

- brand "DEF.", model name "Def One"
- the four hotspots become: planar driver, memory cushions,
  suspension headband, silver cable
- the performance stats become audio specs
  (102 mm driver, 44 kHz, 32 ohms, 385 g)
- keep every token, every font and the cursor engine
  exactly as they are

My product shots follow the kit's recipe: dark studio,
electric cyan rim light. Filenames match the originals.
03

Shoot your product with the kit's recipe

Gauss documents its photographic grade: night studio, deep blue-black, electric cyan rim light. Generate (or shoot) your product the same way and the kit absorbs it as if it had always been there. Seven images, one shared prompt prefix so the product stays identical from shot to shot.

The Def One photo series — same dark studio grade as the kit

The Def One series — same grade, drop-in filenames

04

The result — same engine, your story

The hotspots now name a transducer, cushions, a headband and a cable. The stats read in kilohertz and ohms instead of horsepower. The reticle still locks, the spec cards still speak, the stage still answers the cursor — none of that was touched.

Def Audio and the Def One are fictional — the images were generated with the same pipeline as the kit's own photography. That's the point: whatever your product is, the recipe is written down and the engine already works.

Every kit adapts like this.
