# Protokit

> Prototype kits for mobile and web that coding agents build 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.

## 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/protokit/blob/main/apps/mobile/AGENTS.md): stack, commands, how to build a prototype, gotchas
- [DESIGN_SYSTEM.md](https://github.com/itsHendri/protokit/blob/main/apps/mobile/DESIGN_SYSTEM.md): tokens, the component registry, patterns, anti-patterns, the hallucination guard
- [DESIGN.md](https://github.com/itsHendri/protokit/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.
- Text through `<Text variant>` from components/ui/text; icons through `<Icon as={…} />` (lucide).
- Check every screen in light and dark.

### Tokens

Colours are semantic names only, used as Tailwind classes (`bg-primary`, `text-muted-foreground`,
`border-border`, `bg-success/15`). Never hex, never Tailwind palette colours. Both themes are
required; every fill/foreground pairing clears WCAG AA (4.5:1), enforced by `npm run tokens:build`.
A tone's own text on its own tint (`text-success` on `bg-success/15`) clears AA only for these
tints; on a stronger one, put `text-foreground` on the tint:
primary up to /5, success up to /5, warning up to /5, info up to /15, destructive up to /5.

## Web kit

> A brand-agnostic Next.js prototype kit (App Router, Tailwind 4, shadcn/ui) for dashboards, marketing pages and
> AI product interfaces. Pages 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/protokit/blob/main/apps/web/AGENTS.md): stack, commands, how to build a prototype, gotchas
- [DESIGN_SYSTEM.md](https://github.com/itsHendri/protokit/blob/main/apps/web/DESIGN_SYSTEM.md): tokens, the component registry, patterns, anti-patterns, the hallucination guard
- [DESIGN.md](https://github.com/itsHendri/protokit/blob/main/apps/web/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 inline colour styles.
- Icons from lucide-react. Charts take colours from `var(--chart-1)`…`--chart-5`.
- Check every page in light and dark, at 375px and 1280px wide.

### Tokens

Colours are semantic names only, used as Tailwind classes (`bg-primary`, `text-muted-foreground`,
`border-border`, `bg-success/15`). Never hex, never Tailwind palette colours. Both themes are
required; every fill/foreground pairing clears WCAG AA (4.5:1), enforced by `npm run tokens:build`.
A tone's own text on its own tint (`text-success` on `bg-success/15`) clears AA only for these
tints; on a stronger one, put `text-foreground` on the tint:
primary up to /5, success up to /5, warning up to /5, info up to /15, destructive up to /5.

- Radius (`rounded-*`): sm 6px · md 8px · lg 10px · xl 16px · 2xl 20px (multiples of `--radius` = 10px); buttons use `rounded-md`
- Depth: `shadow-sm` (controls, cards), `shadow-md` (raised, popovers), `shadow-lg` (menus, dialogs) are the theme's three elevation levels; no shadow colour modifiers on surfaces (thumbs and floating elements may add `shadow-black/20`)
- Border `border` 1px · icon stroke 2 (an Icon's `strokeWidth` is relative to 2)
- Fonts: headings system, body system, mono system (applied by Text; `font-heading` makes any Text a heading, `font-mono` code and figures)

# Docs


- **Get started**
- [How it works](/docs): A prototype kit an agent can build from without making things up.
- [Install](/docs/install): Two kits, three ways in, and the one prompt that sets an agent up.
- [Native setup](/docs/mobile): Run the native kit, make it yours, and share it.
- [Web setup](/docs/web): Run the web kit, make it yours, and share it.

- **Design system**
- [Foundations](/docs/foundations): Colour, spacing, radius, type and motion, from one token file.
- [Themes](/docs/themes): Pick a theme on this site, watch both kits change live, then commit it to your project with one code.
- [Patterns](/docs/patterns): How screens are put together in each kit, and what to avoid. Generated from the kits' DESIGN_SYSTEM.md.

- **Project**
- [Changelog](/docs/changelog): What changed, newest first.
