# Uno Toolkit NavigationBar — Agent Skill
## Workflow
> **Docs lookup:** call `uno_platform_docs_search(...)` first, then `uno_platform_docs_fetch(sourcePath="…")` using the `sourcePath` field from a result (a relative `.md` path; add the result's `anchor` for a section). Never pass a URL, a `.html` link, or a hand-built path.
### Step 1: Fetch the NavigationBar Documentation
```
uno_platform_docs_search("Uno Toolkit NavigationBar app bar MainCommand PrimaryCommands")
```
Primary documentation page:
- **NavigationBar**: `external/uno.toolkit.ui/doc/controls/NavigationBar.md`
Fetch the page:
```
uno_platform_docs_fetch(sourcePath="external/uno.toolkit.ui/doc/controls/NavigationBar.md")
```
### Step 2: For Chefs Examples
```
uno_platform_docs_search("NavigationBar Chefs app example navigation back")
```
## Critical Rules
- **`MainCommand` is an `AppBarButton`** — there is no dedicated `NavigationBarMainCommand` type. Use `<utu:NavigationBar.MainCommand><AppBarButton Icon="Back" Command="{Binding GoBackCommand}"/></utu:NavigationBar.MainCommand>` (or equivalent attribute form). The same `AppBarButton` type is used for `PrimaryCommands` and `SecondaryCommands` items.
## Key Principles (Stable)
- `MainCommand` — the back-button slot; an `AppBarButton` instance
- `PrimaryCommands` — action `AppBarButton`s displayed on the right
- `SecondaryCommands` — overflow `AppBarButton`s in the overflow menu
- Two rendering modes: `Windows` (XAML drawn) and `Native` (platform AppBar on iOS/Android)
- Content property is the title
- XAML namespace: `xmlns:utu="using:Uno.Toolkit.UI"`
