Smallstep2022–Current
We rebuilt the design system so an agent picks the mapped component instead of inventing an API.
Renzo Bianchi
Product designer who builds
I design product UI and the systems behind it. Lately, I ship them too.
Fourteen years making interfaces, most of them for US startups through StudioBox, the design studio I co-founded. With AI tooling I take a design all the way to production. Those years are what let me steer the models, so what comes out is still the design I intended.
Day to day, I look after the design systems and the products at Smallstep, and at Cravel, which I also co-founded.
Lately
Tools
artifact-lab
The bench where my UI experiments start: live knobs, a wallpaper viewport, and a recordable showcase. What graduates lands in Explorations; the rest stays here, still moving.
html-skill
Turns an agent’s output into one standalone HTML file where you approve, deny, or discuss each idea, and a Copy response button hands your decisions back as the next prompt.
npx skills add renzobianchi/skills --skill htmlarena-design
A design exploration arena: several candidates take the same brief from opposite directions, a judge scores what they rendered, and the winner absorbs the best ideas from the rest, in Paper, Figma, or code.

Notes
The button is the progress bar
A concept for an assistant inside Cravel that asks before it spends a restaurant’s money. Nothing here shipped in Cravel.
The exit is the confirmation
A weekend experiment: four actions on an AI composer, and the animation is the only thing that tells you what happened.
Directing is rejecting
The models will give you something that looks finished. Directing is everything after that.
Selected work

Eight agent-drawn directions for one table toolbar, and a judge that overruled the orchestrator.
