## What it does

The skill inspects and builds Ionic Framework interfaces inside Capacitor applications. It enforces core page architecture with `IonPage`, `IonHeader`, and `IonContent`. You get layout validation that keeps scrolling inside `ion-content` instead of generic container tags. It also enforces current form syntax via `label` and `labelPlacement` on `IonInput` and `IonSelect`.

It includes rules for theming with CSS variables, configuring dark palettes like `palettes/dark.system.css`, and testing both iOS and Material Design modes. The skill also handles upgrades from Ionic 8 to Ionic 9 with `npx @ionic/migrate`. It spots breaking changes such as removed `ion-picker-legacy`, truthy boolean strings on `autocorrect`, React Router 6 requirements, and zoneless Angular setups.

This workflow applies strictly to Ionic components. Do not rely on it for styling pure Tailwind setups or Konsta UI widgets, which need their own specific tools.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill ionic-design -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/ionic-design/SKILL.md

## When to use it
- configure dark palettes and CSS variables for Ionic themes
- migrate components and routing from Ionic 8 to Ionic 9
- fix layout glitches across iOS and Material Design modes
- structure input forms using label and labelPlacement attributes

## Example prompts
- Review our login form and update IonInput fields to modern Ionic 9 syntax.
- Configure the dark system palette using palettes/dark.system.css.
- Help migrate our Capacitor project from Ionic 8 to Ionic 9 using npx @ionic/migrate.

description: Builds and reviews Ionic Framework UI in Capacitor apps (Ionic 9 current, Ionic 8 still common) - page structure (`ion-header`/`ion-content`/`ion-footer`), lists, modern form syntax (`label`/`labelPlacement` on `ion-input`/`ion-select`), sheet modals, tabs + `ion-router-outlet`, CSS variable theming, dark palettes (`palettes/dark.system.css`, `.ion-palette-dark`), iOS vs MD mode, and Ionic 8 -> 9 breaking changes (React Router 6, Vue Router 5, Angular 18-22 zoneless, removed `ion-picker-legacy`, boolean `autocorrect`, `npx @ionic/migrate`). Use when writing Ionic components, theming an Ionic app, fixing platform-mode styling, or upgrading @ionic/react, @ionic/vue, @ionic/angular. Do not use for Konsta UI (konsta-ui), Tailwind setup (tailwind-capacitor), raw safe-area CSS (safe-area-handling), keyboard resize (capacitor-keyboard), or Ionic Appflow/Enterprise migrations (ionic-appflow-migration, ionic-enterprise-sdk-migration).

# Ionic Framework Design

## When to Use

TRIGGER when:
- Writing or reviewing `Ion*` / `ion-*` components in a Capacitor app
- Theming: `--ion-color-*`, dark mode, high contrast, per-platform styles
- iOS vs Material Design mode looks wrong, or `mode` overrides misbehave
- Upgrading Ionic 7/8 -> 9, or errors after `npm i @ionic/*@latest`
- Choosing Ionic vs another UI kit for a new Capacitor app

Do not use:
- Konsta UI components: `konsta-ui`
- Tailwind v4 install / config: `tailwind-capacitor`
- Notch / system bar padding outside Ionic: `safe-area-handling`
- Keyboard covering inputs: `capacitor-keyboard` (Ionic apps use `resize: 'ionic'`)
- Leaving Appflow / Ionic Enterprise plugins: `ionic-appflow-migration`, `ionic-enterprise-sdk-migration`

## Versions (October 2026)

| Package | Current | Notes |
|---------|---------|-------|
| `@ionic/core`, `@ionic/react`, `@ionic/vue`, `@ionic/angular` | 9.x (`latest`) | 8.x on `v8-lts` tag |
| `ionicons` | 8.x | |
| Ionic 9 minimums | Capacitor 7+, iOS 16+, Android Chromium 89+, Angular 18-22, React 18/19 + React Router 6.4+, Vue 3.5 + vue-router 5, TypeScript 5.4+ | |

Check installed versions first: `npm ls @ionic/core @ionic/react @ionic/vue @ionic/angular`. Write code for the installed major; do not mix v8 and v9 APIs.

## Workflow

1. **Inspect** framework, Ionic major, router version, global CSS imports, `setupIonicReact` / `IonicVue` / `provideIonicAngular` config, `capacitor.config` `Keyboard.resize`.
2. **Upgrading?** Load [references/ionic-9-migration.md](references/ionic-9-migration.md); run `npx @ionic/migrate` in preview first, report findings, then apply.
3. **Components**: [references/components.md](references/components.md) for page shell, lists, forms, overlays, tabs.
