## What it does

This skill walks through structuring a .NET MAUI app with Shell. It covers the `FlyoutItem`, `TabBar`, `Tab`, and `ShellContent` hierarchy in `AppShell.xaml`, plus route registration for pages outside that hierarchy. Transitions use `GoToAsync`, with guidance on passing parameters and handling back navigation.

The guide covers receiving values with `IQueryAttributable` and sending an object through `ShellNavigationQueryParameters`. It also explains navigation events and confirmation before leaving a page. Register a route before navigating to a page outside the visual hierarchy; otherwise, the app throws at runtime.

You’ll need a .NET MAUI project whose root shell is `AppShell.xaml`, along with `ContentPage` pages. This guidance is for Shell-based apps, not projects built around `NavigationPage` alone. External URL deep links and page data binding fall outside its scope.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add dotnet/skills --skill maui-shell-navigation -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add dotnet/skills --skill maui-shell-navigation -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add dotnet/skills --skill maui-shell-navigation -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dotnet/skills maui-shell-navigation
```

2. **Manually: put the files in place**

```

2. **Platform CLI**
```bash
gemini skills install https://github.com/dotnet/skills --path plugins/dotnet-maui/skills/maui-shell-navigation
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dotnet/skills --skill maui-shell-navigation -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/dotnet/skills/tree/HEAD/plugins/dotnet-maui/skills/maui-shell-navigation/SKILL.md

## When to use it
- build tabs and a flyout menu in `AppShell.xaml`
- register a route for a detail page
- pass navigation parameters between pages
- ask for confirmation before navigating back

## Example prompts
- Set up Shell tabs and a flyout menu in my .NET MAUI project.
- Add a `GoToAsync` transition to the details page and register its route.
- Pass an object between pages and confirm before navigating back.

  Guide for implementing Shell-based navigation in .NET MAUI apps. Covers AppShell
  setup, visual hierarchy (FlyoutItem, TabBar, Tab, ShellContent), URI-based navigation
  with GoToAsync, route registration, query parameters, back navigation, flyout and
  tab configuration, navigation events, and navigation guards.
  Use when: setting up Shell navigation, adding tabs or flyout menus, navigating between
  pages with GoToAsync, passing parameters between pages, registering routes, customizing
  back button behavior, or guarding navigation with confirmation dialogs.
  Do not use for: deep linking from external URLs (see .NET MAUI deep linking
  documentation), data binding on pages (use maui-data-binding), dependency injection
  setup (use maui-dependency-injection), or NavigationPage-only apps that don't use Shell.

# .NET MAUI Shell Navigation

Implement page navigation in .NET MAUI apps using Shell. Shell provides URI-based navigation, a flyout menu, tab bars, and a four-level visual hierarchy — all configured declaratively in XAML.

## When to Use

- Setting up top-level app navigation with tabs or a flyout menu
- Navigating between pages programmatically with `GoToAsync`
- Passing data between pages via query parameters or object parameters
- Registering detail-page routes for push navigation
- Guarding navigation with confirmation dialogs (e.g., unsaved changes)
- Customizing back button behavior per page

## When Not to Use

- Deep linking from external URLs or app links — see [.NET MAUI deep linking docs](https://learn.microsoft.com/dotnet/maui/fundamentals/app-links)
- Data binding on navigation target pages — use `maui-data-binding`
- Dependency injection for pages and view models — use `maui-dependency-injection`
- Apps using `NavigationPage` without Shell (different navigation API)

## Inputs

- A .NET MAUI project with `AppShell.xaml` as the root shell
- Pages (`ContentPage`) to navigate between
- Route names for detail pages not in the visual hierarchy

## Rules That Change the Answer

These are the Shell-specific decisions that are easy to get wrong. Apply them
whenever they are relevant to what the user asked.

| Situation | Do this | Not this |
|---|---|---|
| Declaring pages in `AppShell.xaml` | With `xmlns:views="clr-namespace:MyApp.Views"` declared: `<ShellContent ContentTemplate="{DataTemplate views:MyPage}" />` — the page is created on first navigation | `<ShellContent><views:MyPage /></ShellContent>`, which constructs **every** page at startup |
| Navigating to a page not in the visual hierarchy | `Routing.RegisterRoute("details", typeof(DetailsPage))` first | Calling `GoToAsync("details")` unregistered — it throws at runtime |
```
