+# GitHub Copilot & Claude Code Instructions
+
+You are an assistant helping with development of the Home Assistant frontend. The frontend is built using Lit-based Web Components and TypeScript, providing a responsive and performant interface for home automation control.
+
+**Note**: This file contains high-level guidelines and references to implementation patterns. For detailed component documentation, API references, and usage examples, refer to the `gallery/` directory.
+
+## Table of Contents
+
+- [Quick Reference](#quick-reference)
+- [Core Architecture](#core-architecture)
+- [Development Standards](#development-standards)
+- [Component Library](#component-library)
+- [Common Patterns](#common-patterns)
+- [Text and Copy Guidelines](#text-and-copy-guidelines)
+- [Development Workflow](#development-workflow)
+- [Review Guidelines](#review-guidelines)
+
+## Quick Reference
+
+### Essential Commands
+
+```bash
+yarn lint          # ESLint + Prettier + TypeScript + Lit
+yarn format        # Auto-fix ESLint + Prettier
+yarn lint:types    # TypeScript compiler (run WITHOUT file arguments)
+yarn test          # Vitest
+script/develop     # Development server
+```
+
+> **WARNING:** Never run `tsc` or `yarn lint:types` with file arguments (e.g., `yarn lint:types src/file.ts`). When `tsc` receives file arguments, it ignores `tsconfig.json` and emits `.js` files into `src/`, polluting the codebase. Always run `yarn lint:types` without arguments. For individual file type checking, rely on IDE diagnostics. If `.js` files are accidentally generated, clean up with `git clean -fd src/`.
+
+### Component Prefixes
+
+- `ha-` - Home Assistant components
+- `hui-` - Lovelace UI components
+- `dialog-` - Dialog components
+
+### Import Patterns
+
+```typescript
+import type { HomeAssistant } from "../types";
+import { fireEvent } from "../common/dom/fire_event";
+import { showAlertDialog } from "../dialogs/generic/show-alert-dialog";
+```
+
+## Core Architecture
+
+The Home Assistant frontend is a modern web application that:
+
+- Uses Web Components (custom elements) built with Lit framework
+- Is written entirely in TypeScript with strict type checking
+- Communicates with the backend via WebSocket API
+- Provides comprehensive theming and internationalization
+
+## Development Standards
+
+### Code Quality Requirements
+
+**Linting and Formatting (Enforced by Tools)**
+
+- ESLint config extends Airbnb, TypeScript strict, Lit, Web Components, Accessibility
+- Prettier with ES5 trailing commas enforced
+- No console statements (`no-console: "error"`) - use proper logging
+- Import organization: No unused imports, consistent type imports
+
+**Naming Conventions**
+
+- PascalCase for types and classes
+- camelCase for variables, methods
+- Private methods require leading underscore
+- Public methods forbid leading underscore
+
+### TypeScript Usage
+
+- **Always use strict TypeScript**: Enable all strict flags, avoid `any` types
+- **Proper type imports**: Use `import type` for type-only imports
+- **Define interfaces**: Create proper interfaces for data structures
+- **Type component properties**: All Lit properties must be properly typed
+- **No unused variables**: Prefix with `_` if intentionally unused
+- **Consistent imports**: Use `@typescript-eslint/consistent-type-imports`
+
+```typescript
+// Good
+import type { HomeAssistant } from "../types";
+
+interface EntityConfig {
+  entity: string;
+  name?: string;
+}
+
+@property({ type: Object })
+hass!: HomeAssistant;
+
+// Bad
+@property()
+hass: any;
+```
+
+### Web Components with Lit
+
+- **Use Lit 3.x patterns**: Follow modern Lit practices
+- **Extend appropriate base classes**: Use `LitElement`, `SubscribeMixin`, or other mixins as needed
+- **Define custom element names**: Use `ha-` prefix for components
+
+```typescript
+@customElement("ha-my-component")
+export class HaMyComponent extends LitElement {
+  @property({ attribute: false })
+  hass!: HomeAssistant;
+
+  @state()
+  private _config?: MyComponentConfig;
+
+  static get styles() {
+    return css`
+      :host {
+        display: block;
+      }
+    `;
+  }
+
+  render() {
+    return html`<div>Content</div>`;
+  }
+}
+```
+
+### Component Guidelines
+
+- **Use composition**: Prefer composition over inheritance
+- **Lazy load panels**: Heavy panels should be dynamically imported
+- **Optimize renders**: Use `@state()` for internal state, `@property()` for public API
+- **Handle loading states**: Always show appropriate loading indicators
+- **Support themes**: Use CSS custom properties from theme
+
+### Data Management
+
+- **Use WebSocket API**: All backend communication via home-assistant-js-websocket
+- **Cache appropriately**: Use collections and caching for frequently accessed data
+- **Handle errors gracefully**: All API calls should have error handling
+- **Update real-time**: Subscribe to state changes for live updates
+
+```typescript
+// Good
+try {
+  const result = await fetchEntityRegistry(this.hass.connection);
+  this._processResult(result);
+} catch (err) {
+  showAlertDialog(this, {
+    text: `Failed to load: ${err.message}`,
+  });
+}
+```
+
+### Styling Guidelines
+
+- **Use CSS custom properties**: Leverage the theme system
+- **Use spacing tokens**: Prefer `--ha-space-*` tokens over hardcoded values for consistent spacing
+  - Spacing scale: `--ha-space-1` (4px) through `--ha-space-20` (80px) in 4px increments
+  - Defined in `src/resources/theme/core.globals.ts`
+  - Common values: `--ha-space-2` (8px), `--ha-space-4` (16px), `--ha-space-8` (32px)
+- **Mobile-first responsive**: Design for mobile, enhance for desktop
+- **Follow Material Design**: Use Material Web Components where appropriate
+- **Support RTL**: Ensure all layouts work in RTL languages
+
+```typescript
+static get styles() {
+  return css`

+
+### View Transitions
+
+The View Transitions API creates smooth animations between DOM state changes. When implementing view transitions:
+
+**Core Resources:**
+
+- **Utility wrapper**: `src/common/util/view-transition.ts` - `withViewTransition()` function with graceful fallback
+- **Real-world example**: `src/util/launch-screen.ts` - Launch screen fade pattern with browser support detection
+- **Animation keyframes**: `src/resources/theme/animations.globals.ts` - Global `fade-in`, `fade-out`, `scale` animations
+- **Animation duration**: `src/resources/theme/core.globals.ts` - `--ha-animation-duration-fast` (150ms), `--ha-animation-duration-normal` (250ms), `--ha-animation-duration-slow` (350ms) (all respect `prefers-reduced-motion`)
+
+**Implementation Guidelines:**
+
+1. Always use `withViewTransition()` wrapper for automatic fallback
+2. Keep transitions simple (subtle crossfades and fades work best)
+3. Use `--ha-animation-duration-*` CSS variables for consistent timing (`fast`, `normal`, `slow`)
+4. Assign unique `view-transition-name` to elements (must be unique at any given time)
+5. For Lit components: Override `performUpdate()` or use `::part()` for internal elements
+
+**Default Root Transition:**
+
+By default, `:root` receives `view-transition-name: root`, creating a full-page crossfade. Target with [`::view-transition-group(root)`](https://developer.mozilla.org/en-US/docs/Web/CSS/::view-transition-group) to customize the default page transition.
+
+**Important Constraints:**
+
+- Each `view-transition-name` must be unique at any given time
+- Only one view transition can run at a time
+- **Shadow DOM incompatibility**: View transitions operate at document level and do not work within Shadow DOM due to style isolation ([spec discussion](https://github.com/w3c/csswg-drafts/issues/10303)). For web components, set `view-transition-name` on the `:host` element or use document-level transitions
+
+**Specification & Documentation:**
+
+For browser support, API details, and current specifications, refer to these authoritative sources (note: check publication dates as specs evolve):
+
+- [MDN: View Transition API](https://developer.mozilla.org/en-US/docs/Web/API/View_Transition_API) - Comprehensive API reference
+- [Chrome for Developers: View Transitions](https://developer.chrome.com/docs/web-platform/view-transitions) - Implementation guide and examples
+- [W3C Draft Specification](https://drafts.csswg.org/css-view-transitions/) - Official specification (evolving)
+
+### Performance Best Practices
+
+- **Code split**: Split code at the panel/dialog level
+- **Lazy load**: Use dynamic imports for heavy components
+- **Optimize bundle**: Keep initial bundle size minimal
+- **Use virtual scrolling**: For long lists, implement virtual scrolling
+- **Memoize computations**: Cache expensive calculations
+
+### Testing Requirements
+
+- **Write tests**: Add tests for data processing and utilities
+- **Test with Vitest**: Use the established test framework
+- **Mock appropriately**: Mock WebSocket connections and API calls
+- **Test accessibility**: Ensure components are accessible
+
+## Component Library
+
+### Dialog Component
+
+**Opening Dialogs (Fire Event Pattern - Recommended):**
+
+```typescript
+fireEvent(this, "show-dialog", {
+  dialogTag: "dialog-example",
+  dialogImport: () => import("./dialog-example"),
+  dialogParams: { title: "Example", data: someData },
+});
+```
+
+**Dialog Implementation Requirements:**
+
+- Use `ha-dialog` component
+- Implement `HassDialog<T>` interface
+- Use `@state() private _open = false` to control dialog visibility
+- Set `_open = true` in `showDialog()`, `_open = false` in `closeDialog()`
+- Return `nothing` when no params (loading state)
+- Fire `dialog-closed` event in `_dialogClosed()` handler
+- Use `header-title` attribute for simple titles
+- Use `header-subtitle` attribute for simple subtitles
+- Use slots for custom content where the standard attributes are not enough
+- Use `ha-dialog-footer` with `primaryAction`/`secondaryAction` slots for footer content
+- Add `autofocus` to first focusable element (e.g., `<ha-form autofocus>`). The component may need to forward this attribute internally.
+
+**Dialog Sizing:**
+
+- Use `width` attribute with predefined sizes: `"small"` (320px), `"medium"` (560px - default), `"large"` (720px), or `"full"`
+- Custom sizing is NOT recommended - use the standard width presets
+
+**Button Appearance Guidelines:**
+
+- **Primary action buttons**: Default appearance (no appearance attribute) or omit for standard styling
+- **Secondary action buttons**: Use `appearance="plain"` for cancel/dismiss actions
+- **Destructive actions**: Use `appearance="filled"` for delete/remove operations (combined with appropriate semantic styling)
+- **Button sizes**: Use `size="small"` (32px height) or default/medium (40px height)
+- Always place primary action in `slot="primaryAction"` and secondary in `slot="secondaryAction"` within `ha-dialog-footer`
+
+**Gallery Documentation:**
+
+- `gallery/src/pages/components/ha-dialog.markdown`
+- `gallery/src/pages/components/ha-dialogs.markdown`
+
+### Form Component (ha-form)
+
+- Schema-driven using `HaFormSchema[]`
+- Supports entity, device, area, target, number, boolean, time, action, text, object, select, icon, media, location selectors
+- Built-in validation with error display
+- Use `computeLabel`, `computeError`, `computeHelper` for translations
+
+```typescript
+<ha-form
+  .hass=${this.hass}
+  .data=${this._data}
+  .schema=${this._schema}
+  .error=${this._errors}
+  .computeLabel=${(schema) => this.hass.localize(`ui.panel.${schema.name}`)}
+  @value-changed=${this._valueChanged}
+></ha-form>
+```
+
+**Gallery Documentation:**
+
+- `gallery/src/pages/components/ha-form.markdown`
+
+### Alert Component (ha-alert)
+
+- Types: `error`, `warning`, `info`, `success`
+- Properties: `title`, `alert-type`, `dismissable`, `icon`, `action`, `rtl`
+- Content announced by screen readers when dynamically displayed
+
+```html
+<ha-alert alert-type="error">Error message</ha-alert>
+<ha-alert alert-type="warning" title="Warning">Description</ha-alert>
+<ha-alert alert-type="success" dismissable>Success message</ha-alert>
+```
+
+**Gallery Documentation:**
+
+- `gallery/src/pages/components/ha-alert.markdown`
+
+### Keyboard Shortcuts (ShortcutManager)
+
+The `ShortcutManager` class provides a unified way to register keyboard shortcuts with automatic input field protection.
+
+**Key Features:**
+
+- Automatically blocks shortcuts when input fields are focused
+- Prevents shortcuts during text selection (configurable via `allowWhenTextSelected`)
+- Supports both character-based and KeyCode-based shortcuts (for non-latin keyboards)
+
+**Implementation:**
+
+- **Class definition**: `src/common/keyboard/shortcuts.ts`
+- **Real-world example**: `src/state/quick-bar-mixin.ts` - Global shortcuts (e, c, d, m, a, Shift+?) with non-latin keyboard fallbacks
+
+### Tooltip Component (ha-tooltip)
+
+The `ha-tooltip` component wraps Web Awesome tooltip with Home Assistant theming. Use for providing contextual help text on hover.
+
+**Implementation:**
+
+- **Component definition**: `src/components/ha-tooltip.ts`
+- **Usage example**: `src/components/ha-label.ts`
+- **Gallery documentation**: `gallery/src/pages/components/ha-tooltip.markdown`
+
+## Common Patterns
+
+### Creating a Panel
+
+```typescript
+@customElement("ha-panel-myfeature")
+export class HaPanelMyFeature extends SubscribeMixin(LitElement) {
+  @property({ attribute: false })
+  hass!: HomeAssistant;
+
+  @property({ type: Boolean, reflect: true })
+  narrow!: boolean;
+
+  @property()
+  route!: Route;
+
+  hassSubscribe() {
+    return [
+      subscribeEntityRegistry(this.hass.connection, (entities) => {
+        this._entities = entities;
+      }),
+    ];
+  }
+}
+```
+
+#### Creating a Lovelace Card
+
+**Purpose**: Cards allow users to tell different stories about their house (based on gallery)
+
+```typescript
+@customElement("hui-my-card")
+export class HuiMyCard extends LitElement implements LovelaceCard {
+  @property({ attribute: false })
+  hass!: HomeAssistant;
+
+  @state()
+  private _config?: MyCardConfig;
+
+  public setConfig(config: MyCardConfig): void {
+    if (!config.entity) {
+      throw new Error("Entity required");
+    }
+    this._config = config;
+  }
+
+  public getCardSize(): number {
+    return 3; // Height in grid units
+  }
+
+  // Optional: Editor for card configuration
+  public static getConfigElement(): LovelaceCardEditor {
+    return document.createElement("hui-my-card-editor");
+  }
+
+  // Optional: Stub config for card picker
+  public static getStubConfig(): object {
+    return { entity: "" };
+  }
+}
+```
+
+**Card Guidelines:**
+
+- Cards are highly customizable for different households
+- Implement `LovelaceCard` interface with `setConfig()` and `getCardSize()`
+- Use proper error handling in `setConfig()`
+- Consider all possible states (loading, error, unavailable)
+- Support different entity types and states
+- Follow responsive design principles
+- Add configuration editor when needed
+
+### Internationalization
+
+- **Use localize**: Always use the localization system
+- **Add translation keys**: Add keys to src/translations/en.json
+- **Support placeholders**: Use proper placeholder syntax
+
+```typescript
+this.hass.localize("ui.panel.config.updates.update_available", {
+  count: 5,
+});
+```
+
+### Accessibility
+
+- **ARIA labels**: Add appropriate ARIA labels
+- **Keyboard navigation**: Ensure all interactions work with keyboard
+- **Screen reader support**: Test with screen readers
+- **Color contrast**: Meet WCAG AA standards
+
+## Development Workflow
+
+### Setup and Commands
+
+1. **Setup**: `script/setup` - Install dependencies
+2. **Develop**: `script/develop` - Development server
+3. **Lint**: `yarn lint` - Run all linting before committing
+4. **Test**: `yarn test` - Add and run tests
+5. **Build**: `script/build_frontend` - Test production build
+
+### Common Pitfalls to Avoid
+
+- Don't use `querySelector` - Use refs or component properties
+- Don't manipulate DOM directly - Let Lit handle rendering
+- Don't use global styles - Scope styles to components
+- Don't block the main thread - Use web workers for heavy computation
+- Don't ignore TypeScript errors - Fix all type issues
+
+### Security Best Practices
+
+- Sanitize HTML - Never use `unsafeHTML` with user content
+- Validate inputs - Always validate user inputs
+- Use HTTPS - All external resources must use HTTPS
+- CSP compliance - Ensure code works with Content Security Policy
+
+### Pull Requests
+
+When creating a pull request, you **must** use the PR template located at `.github/PULL_REQUEST_TEMPLATE.md`. Read the template file and use its full content as the PR body, filling in each section appropriately.
+
+- Do not omit, reorder, or rewrite the template sections
+- Check the appropriate "Type of change" box based on the changes
+- Do not check the checklist items on behalf of the user — those are the user's responsibility to review and check
+- If the PR includes UI changes, remind the user to add screenshots or a short video to the PR after creating it
+- Be simple and user friendly — explain what the change does, not implementation details
+- Use markdown so the user can copy it
+
+### Text and Copy Guidelines
+
+#### Terminology Standards
+
+**Delete vs Remove** (Based on gallery/src/pages/Text/remove-delete-add-create.markdown)
+
+- **Use "Remove"** for actions that can be restored or reapplied:
+  - Removing a user's permission
+  - Removing a user from a group
+  - Removing links between items
+  - Removing a widget from dashboard
+  - Removing an item from a cart
+- **Use "Delete"** for permanent, non-recoverable actions:
+  - Deleting a field
+  - Deleting a value in a field
+  - Deleting a task
+  - Deleting a group
+  - Deleting a permission
+  - Deleting a calendar event
+
+**Create vs Add** (Create pairs with Delete, Add pairs with Remove)
+
+- **Use "Add"** for already-existing items:
+  - Adding a permission to a user
+  - Adding a user to a group
+  - Adding links between items
+  - Adding a widget to dashboard
+  - Adding an item to a cart
+- **Use "Create"** for something made from scratch:
+  - Creating a new field
+  - Creating a new task
+  - Creating a new group
+  - Creating a new permission
+  - Creating a new calendar event
+
+#### Writing Style (Consistent with Home Assistant Documentation)
+
+- **Use American English**: Standard spelling and terminology
+- **Friendly, informational tone**: Be inspiring, personal, comforting, engaging
+- **Address users directly**: Use "you" and "your"
+- **Be inclusive**: Objective, non-discriminatory language
+- **Be concise**: Use clear, direct language
+- **Be consistent**: Follow established terminology patterns
+- **Use active voice**: "Delete the automation" not "The automation should be deleted"
+- **Avoid jargon**: Use terms familiar to home automation users
+
+#### Language Standards
+
+- **Always use "Home Assistant"** in full, never "HA" or "HASS"
+- **Avoid abbreviations**: Spell out terms when possible
+- **Use sentence case everywhere**: Titles, headings, buttons, labels, UI elements
+  - ✅ "Create new automation"
+  - ❌ "Create New Automation"
+  - ✅ "Device settings"
+  - ❌ "Device Settings"
+- **Oxford comma**: Use in lists (item 1, item 2, and item 3)
+- **Replace Latin terms**: Use "like" instead of "e.g.", "for example" instead of "i.e."
+- **Avoid CAPS for emphasis**: Use bold or italics instead
+- **Write for all skill levels**: Both technical and non-technical users
+
+#### Key Terminology
+
+- **"integration"** (preferred over "component")
+- **Technical terms**: Use lowercase (automation, entity, device, service)
+
+#### Translation Considerations
+
+- **Add translation keys**: All user-facing text must be translatable
+- **Use placeholders**: Support dynamic content in translations
+- **Keep context**: Provide enough context for translators
+
+```typescript
+// Good
+this.hass.localize("ui.panel.config.automation.delete_confirm", {
+  name: automation.alias,
+});
+
+// Bad - hardcoded text
+("Are you sure you want to delete this automation?");
+```
+
+### Common Review Issues (From PR Analysis)
+
+#### User Experience and Accessibility
+
+- **Form validation**: Always provide proper field labels and validation feedback
+- **Form accessibility**: Prevent password managers from incorrectly identifying fields
+- **Loading states**: Show clear progress indicators during async operations
+- **Error handling**: Display meaningful error messages when operations fail
+- **Mobile responsiveness**: Ensure components work well on small screens
+- **Hit targets**: Make clickable areas large enough for touch interaction
+- **Visual feedback**: Provide clear indication of interactive states
+
+#### Dialog and Modal Patterns
+
+- **Dialog width constraints**: Respect minimum and maximum width requirements
+- **Interview progress**: Show clear progress for multi-step operations
+- **State persistence**: Handle dialog state properly during background operations
+- **Cancel behavior**: Ensure cancel/close buttons work consistently
+- **Form prefilling**: Use smart defaults but allow user override
+
+#### Component Design Patterns
+
+- **Terminology consistency**: Use "Join"/"Apply" instead of "Group" when appropriate
+- **Visual hierarchy**: Ensure proper font sizes and spacing ratios
+- **Grid alignment**: Components should align to the design grid system
+- **Badge placement**: Position badges and indicators consistently
+- **Color theming**: Respect theme variables and design system colors
+
+#### Code Quality Issues
+
+- **Null checking**: Always check if entities exist before accessing properties
+- **TypeScript safety**: Handle potentially undefined array/object access
+- **Import organization**: Remove unused imports and use proper type imports
+- **Event handling**: Properly subscribe and unsubscribe from events
+- **Memory leaks**: Clean up subscriptions and event listeners
+
+#### Configuration and Props
+
+- **Optional parameters**: Make configuration fields optional when sensible
+- **Smart defaults**: Provide reasonable default values
+- **Future extensibility**: Design APIs that can be extended later
+- **Validation**: Validate configuration before applying changes
+
