 ### Core rules
 
+- Activate the `nativephp-mobile-ui` skill when writing a screen's view. It lists each element's props and
+  events, list-item swipe actions, and the text input traps.
+- Text fields are `outlined-text-input`, `filled-text-input` and `bare-text-input`. There is no `text-input`.
+  Bind them with `native:model.debounce.300ms` and also read the text `@submit` passes as the handler's last
+  argument; live binding can drop characters under fast typing.
+- `<native:list-item>` props are camelCase as written (`leadingCheckbox`, `trailingIconButton`). Swipe actions
+  only work on list items that are direct children of `<native:list>`.
 - Visual styling is theme-driven ("Model 3"): buttons, inputs, toggles, and
   other controls take their colors, radii, and typography from the theme
   (`Native\Mobile\UI\Theme`). Use semantic props like `variant="primary"`

+name: nativephp-mobile-ui
+description: "Element reference for nativephp/mobile-ui, the plugin that renders every NativePHP EDGE element. Activate when writing or changing a NativePHP screen's Blade view: layout (column, row, stack, scroll-view), text, button, the text inputs (outlined-text-input, filled-text-input, bare-text-input), list and list-item (leading/trailing slots, swipe actions, trailing icon buttons), icon, top-bar, toggle, checkbox, select, and their events and native:model binding."
+---
+
+# nativephp/mobile-ui elements
+
+Every `<native:*>` tag is drawn by this plugin, as SwiftUI on iOS and Jetpack Compose on Android. The plugin must be
+registered in `plugins()` in `app/Providers/NativeServiceProvider.php` (`php artisan native:plugin:register
+nativephp/mobile-ui`). The `native:` prefix is optional (`<column>` works), but use it.
+
+## Events
+
+`@press` (alias `@tap`), `@longPress`, `@doubleTap`, `@change`, `@submit`, `@refresh`, `@endReached`. The value is a
+public method name or `method(arg, ...)` with JSON arguments: `select('abc')`, `remove({{ $id }})`. The element's
+own value is appended after your arguments: the text for `@submit` and `@change` on text inputs, a bool for
+checkboxes and switches. Any element takes `@press`, including rows and columns. A misspelled event attribute is
+dropped without an error.
+
+## Elements
+
+| Element | Props that matter |
+|---|---|
+| `column`, `row`, `stack`, `scroll-view`, `spacer`, `divider`, `pressable` | Tailwind `class`: `w-full h-full flex-1 gap-N p-N px-N items-center justify-between rounded-lg bg-theme-*` |
+| `text` (slot is the text) | `class` (`text-lg font-bold line-through underline text-theme-on-surface`), `font` |
+| `button` | label as slot or `label`; `variant` primary\|secondary\|destructive\|success\|ghost; `size` sm\|md\|lg; `icon`, `icon-trailing`, `ios-icon`, `android-icon`, `disabled`, `loading`, `a11y-label` |
+| `outlined-text-input`, `filled-text-input`, `bare-text-input` | `native:model`, `placeholder`, `label`, `@submit`, `@change`, `keyboard` (text\|number\|decimal\|email\|phone\|url\|password), `secure`, `revealable`, `multiline`, `max-length`, `autofocus`, `leading-icon`, `trailing-icon`, `error`, `supporting` |
+| `list` | `separator`, `plain`, `horizontal`, `on-refresh`, `on-end-reached`. Children: `list-item` or any element |
+| `list-item` | see below |
+| `icon` | `name` (`star.fill`, `trash`, `plus`), or per platform `ios="checkmark.circle.fill" android="check_circle"`, `:size="20"`, `class="text-theme-primary"` |
+| `top-bar` | `title`, `subtitle`, `back`. Put it at the top level of the view |
+| also | `toggle`, `checkbox`, `slider`, `select`, `radio-group`, `chip`, `badge`, `date-picker`, `modal`, `bottom-sheet`, `tab-row`, `progress-bar`, `activity-indicator` |
+
+There is no `text-input` element. It throws "Unknown native element type: text_input".
+
+## Text inputs
+
+```blade
+<native:outlined-text-input class="flex-1" placeholder="New note" ref="title-input"
+    native:model.debounce.300ms="title" @submit="save" />
+```
+
+- Use `native:model.debounce.300ms` (`.debounce` alone is 300ms) or `.blur`. The default live mode syncs every
+  keystroke and echoes the value back into the field, which drops or reorders characters under fast typing.
+- Take the text from `@submit` too. The handler gets it as its last argument, so a button tapped inside the
+  debounce window can't save a stale value:
+
+```php
+public function save(?string $submitted = null): void
+{
+    $title = trim($submitted ?? $this->title);
+    // ...
+    $this->title = '';   // clears the field on the next render
+}
+```
+
+- `keep-focus-on-submit` only works on iOS.
+
+## List items
+
+Props are written camelCase, exactly as below. Use `:prop` for PHP values.
+
+- Text: `headline`, `supporting`, `overline`, `headlineColor`.
+- Leading slot, pick one: `leadingIcon`, `leadingCheckbox`, `leadingRadio`, `leadingMonogram`, `leadingAvatar`,
+  `leadingImage`. Changes go to `on-leading-change`.
+- Trailing slot, pick one: `trailingIcon`, `trailingText`, `trailingCheckbox`, `trailingSwitch`,
+  `trailingIconButton`. Changes go to `on-trailing-change`; the icon button's press goes to `on-trailing-press`.
+- Swipe: `:trailing-actions` and `:leading-actions` take arrays of `method`, `label`, `icon` (or `ios` and
+  `android`), `tint`, `role` (`destructive` makes it red). `on-swipe-delete` is the single-action shortcut.
+- `@press` on the row, `disabled`, `native:key` for a stable identity.
+
+```blade
+<native:list class="w-full flex-1" separator>
+    @foreach ($notes as $note)
+        <native:list-item native:key="note-{{ $note->id }}"
+            :headline="$note->title"
+            :supporting="$note->pinned ? 'Pinned' : ''"
+            :leadingCheckbox="$note->pinned" on-leading-change="pin({{ $note->id }})"
+            trailingIconButton="trash" trailing-a11y-label="Delete" on-trailing-press="remove({{ $note->id }})"
+            :trailing-actions="[['method' => 'remove('.$note->id.')', 'label' => 'Delete', 'icon' => 'trash', 'role' => 'destructive']]" />
+    @endforeach
+</native:list>
+```
+
+Swipe actions only work on list items that are direct children of `<native:list>`.
+
+A list item can't strike through or restyle its headline. For that, build the row yourself inside a
+`scroll-view`:
+
+```blade
+<native:scroll-view class="w-full flex-1">
+    <native:column class="w-full">
+        @foreach ($notes as $note)
+            <native:row class="w-full items-center gap-3 px-4 py-3" @press="archive({{ $note->id }})">
+                <native:icon :name="$note->archived ? 'checkmark.circle.fill' : 'circle'" :size="22" class="text-theme-primary" />
+                <native:text class="flex-1 {{ $note->archived ? 'line-through text-theme-on-surface-variant' : 'text-theme-on-surface' }}">{{ $note->title }}</native:text>
+                <native:button variant="ghost" size="sm" icon="trash" a11y-label="Delete" @press="remove({{ $note->id }})" />
+            </native:row>
+        @endforeach
+    </native:column>
+</native:scroll-view>
+```
+
+## Layout
+
+- `<native:top-bar>` gives a native navigation bar and handles the safe area. A screen can also return its title
+  from `navTitle(): string`.
+- Add `safe-area` only to screens with no top bar, bottom nav or layout.
+- Colours come from theme tokens (`bg-theme-*`, `text-theme-*`, `border-theme-*` with `primary`, `on-primary`,
+  `surface`, `on-surface`, `surface-variant`, `on-surface-variant`, `background`, `outline`), which switch for dark
+  mode on their own.
+
+## In tests
+
+Node types in `Native::test(...)->tree()` and `assertElement()` are snake_case: `list_item`,
+`outlined_text_input`. A list item's checkbox state is `props.leading_checked`. `assertSee()` finds headlines and
+swipe action labels. `press('remove(5)')` fires whatever callback was registered for that expression.
