## What it does

The skill covers installing and configuring Konsta UI v5 in React 19, Vue 3 and Svelte 5 projects. Styling is CSS-first: `@import 'tailwindcss'` plus `@import 'konsta/react/theme.css'`, with brand colors declared as `--color-brand-*` variables inside `@theme`. The app root gets wrapped in `App` with `theme`, `safeAreas` and `dark` props.

Inside you get a version table for Konsta and Tailwind, the v3/v4 migration path, a symptom-to-fix error table and a post-build checklist. The error table covers unstyled components, dead `ios:`/`material:` classes and Navbar or Tabbar sitting under the system bars. One trap is mixing with Ionic: there you use `KonstaProvider` instead of `App` and keep a single owner of safe areas, otherwise top padding doubles up.

The skill assumes React 19. On React 18 you will hit a `ref`/`forwardRef` warning after upgrading Konsta, so either move React forward or stay on Konsta 4. Dark mode in v5 is class-based and toggled on `<html>`. Konsta handles UI only, so routing, page transitions and the Android back button are yours to wire up.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill konsta-ui -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/konsta-ui/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/konsta-ui/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill konsta-ui -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/konsta-ui/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill konsta-ui -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/konsta-ui/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Cap-go/capgo-skills konsta-ui
```

2. **Manually: put the files in place**
- File: `.github/skills/konsta-ui/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill konsta-ui -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Cap-go/capgo-skills --path skills/konsta-ui
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/konsta-ui/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill konsta-ui -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Cap-go/capgo-skills/tree/HEAD/skills/konsta-ui/SKILL.md

## When to use it
- add Konsta UI v5 to a Capacitor app on React 19
- migrate a project from Konsta v3/v4 to Tailwind v4 CSS config
- find out why components render unstyled
- fix theme switching and platform-based theming
- stop Navbar and Tabbar from overlapping system bars

## Example prompts
- Set up Konsta UI v5 in my Capacitor app with React 19
- My Konsta components render unstyled — find the cause
- Migrate this project off konstaConfig in tailwind.config.js to the v5 CSS setup

description: Builds Capacitor app UI with Konsta UI v5 (Tailwind CSS v4-based iOS and Material components for React 19, Vue 3, Svelte 5) - CSS-first setup (`@import 'tailwindcss'; @import 'konsta/react/theme.css';`), `--color-brand-*` colors in `@theme`, `<App theme="ios|material|parent" safeAreas dark>`, `KonstaProvider` when mixing with Ionic, `ios:`/`material:` variants, `pt-safe`/`no-safe-areas` utilities, `k-md-vibrant`/`k-md-monochrome`, and migrating from Konsta v3/v4 `konstaConfig` in `tailwind.config.js`. Use when installing or upgrading Konsta, components render unstyled, theme or dark mode does not switch, or Navbar/Tabbar overlap system bars. Do not use for Ionic components (ionic-design), plain Tailwind setup without Konsta (tailwind-capacitor), or native safe-area/edge-to-edge config (safe-area-handling).

# Konsta UI for Capacitor

## When to Use

TRIGGER when:
- Adding Konsta UI to a Capacitor app or choosing it over Ionic
- Upgrading Konsta v3/v4 (Tailwind v3 `konstaConfig`) to v5 (Tailwind v4)
- Components unstyled, colors ignored, `ios:`/`material:` classes do nothing
- Navbar / Tabbar under the status bar or gesture bar
- Theme should follow platform (`ios` on iPhone, `material` on Android)

Do not use:
- Ionic Framework components or theming: `ionic-design`
- Tailwind install/config without Konsta: `tailwind-capacitor`
- Android SystemBars / edge-to-edge native config: `safe-area-handling`
- Keyboard overlap in forms: `capacitor-keyboard`

## Versions (October 2026)

| Konsta | Tailwind | Frameworks | Config style |
|--------|----------|------------|--------------|
| 5.x (`latest`, 5.5.0) | v4 | React 19 (`ref` as prop), Vue 3, Svelte 5 (runes, snippets) | CSS: `@import 'konsta/<fw>/theme.css'` + `@theme` |
| 4.x | v3 | adds Svelte 5 types | JS: `konstaConfig()` in `tailwind.config.js` |
| 3.x and below | v3 | | JS `konstaConfig()` |

Check first: `npm ls konsta tailwindcss react vue svelte`. Never mix v5 CSS setup with a `tailwind.config.js` `konstaConfig` wrapper.

## Workflow

1. **Inspect** versions, main CSS file, `tailwind.config.*`, `postcss.config.*`, `vite.config.*`, `index.html` viewport meta, whether Ionic is also present.
2. **Install / upgrade** (below). For an existing Tailwind v3 project, migrate Tailwind first (`tailwind-capacitor`).
3. **Wrap the app** in `App` (or `KonstaProvider` with Ionic/Framework7).
4. **Build screens** with components: [references/components.md](references/components.md).
5. **Verify** (below).

Only load a reference when its topic is in play.

## Setup (v5, React shown; Vue/Svelte use `konsta/vue/theme.css` / `konsta/svelte/theme.css`)

```bash
npm i konsta tailwindcss @tailwindcss/vite
```

```ts
// vite.config.ts
import tailwindcss from '@tailwindcss/vite';
````
