# Halftone Design System
> One brand on phone and web: Expo and Next.js kits your coding agent builds from.
Two prototype kits on one set of design tokens: a native kit (Expo, React Native, NativeWind,
react-native-reusables) and a web kit (Next.js, Tailwind 4, shadcn/ui). Each kit lists the only components a
prototype may use. Start with the install guide.
## This site
- [Install guide for agents](https://halftonedesignsystem.com/install.md): pick a kit and a path, then the rules
- [Everything in one file](https://halftonedesignsystem.com/llms-full.txt)
- [shadcn registry for Expo + react-native-reusables (@halftone-native)](https://halftonedesignsystem.com/r/native/registry.json)
- [shadcn registry for Next.js + shadcn/ui (@halftone-web)](https://halftonedesignsystem.com/r/web/registry.json)
- [Studio](https://halftonedesignsystem.com/studio/): people make and keep design systems here (saved in their browser). They hand you an `ht-` theme code or a `.halftone.json`; apply either with `npx halftone-tokens theme apply <code|file>` (the kits' apply-theme skill)
## Native kit
> A brand-agnostic Expo + React Native prototype kit (Expo Router, NativeWind, react-native-reusables).
> Screens are composed ONLY from the components listed below; nothing else exists.
Generated by `npm run registry:build` from registry/components.ts — do not edit by hand.
### Read first
- [AGENTS.md](https://github.com/itsHendri/halftone/blob/main/apps/mobile/AGENTS.md): stack, commands, how to build a prototype, gotchas
- [DESIGN_SYSTEM.md](https://github.com/itsHendri/halftone/blob/main/apps/mobile/DESIGN_SYSTEM.md): tokens, the component registry, patterns, anti-patterns, the hallucination guard
- [DESIGN.md](https://github.com/itsHendri/halftone/blob/main/apps/mobile/DESIGN.md): the design tokens in the DESIGN.md format
### Rules
- Use only the components below, by their exact names. Missing something: stop and say so (the `add-component` skill adds it properly).
- Style with semantic Tailwind classes only. No hex, no Tailwind palette colours, no StyleSheet colours.
- `npm run lint` enforces these rules (`halftone/*`): fix every error before calling a screen done.
- Text through `<Text variant>` from components/ui/text; icons through `<Icon as={…} />` (lucide).
- Check every screen in light and dark.
### Components
#### Actions
- [Button](https://github.com/itsHendri/halftone/blob/main/apps/mobile/components/ui/button.tsx): `variant` default/secondary/outline/ghost/link/destructive · `size` sm/default/lg/icon · children are `<Text>`/`<Icon>` — `<Button variant? size? disabled?><Text>…</Text></Button>`
- [Toggle](https://github.com/itsHendri/halftone/blob/main/apps/mobile/components/ui/toggle.tsx): pressed two-state button — `<Toggle pressed onPressedChange><ToggleIcon as={…} /></Toggle>`
- [ToggleGroup](https://github.com/itsHendri/halftone/blob/main/apps/mobile/components/ui/toggle-group.tsx): `type` single/multiple — `<ToggleGroup type="single|multiple"
