+### Essential Commands
+
+```bash
+yarn lint          # ESLint + Prettier + TypeScript + Lit
+yarn format        # Auto-fix ESLint + Prettier
+yarn lint:types    # TypeScript compiler
+yarn test          # Vitest

+```
+
+### 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
+- **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`
+    :host {
+      --spacing: 16px;
+      padding: var(--spacing);
+      color: var(--primary-text-color);
+      background-color: var(--card-background-color);
+    }
+
+    @media (max-width: 600px) {
+      :host {
+        --spacing: 8px;
+      }
+    }
+  `;
+}
+```
+
+### 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 Components
+
+**Available Dialog Types:**
+
+- `ha-md-dialog` - Preferred for new code (Material Design 3)
+- `ha-dialog` - Legacy component still widely used
+
+**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:**
+
+- Implement `HassDialog<T>` interface
+- Use `createCloseHeading()` for standard headers
+- Import `haStyleDialog` for consistent styling
+- Return `nothing` when no params (loading state)
+- Fire `dialog-closed` event when closing
+- Add `dialogInitialFocus` for accessibility
+
+````
+
+### 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 `dialogInitialFocus` in dialogs
+- 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>
+````
+
+### 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>
+```
+
+## 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 Dialog
+
+```typescript
+@customElement("dialog-my-feature")
+export class DialogMyFeature
+  extends LitElement
+  implements HassDialog<MyDialogParams>
+{
+  @property({ attribute: false })
+  hass!: HomeAssistant;
+
+  @state()
+  private _params?: MyDialogParams;
+
+  public async showDialog(params: MyDialogParams): Promise<void> {
+    this._params = params;
+  }
+
+  public closeDialog(): void {
+    this._params = undefined;
+    fireEvent(this, "dialog-closed", { dialog: this.localName });
+  }
+
+  protected render() {
+    if (!this._params) {
+      return nothing;
+    }
+
+    return html`
+      <ha-dialog
+        open
+        @closed=${this.closeDialog}
+        .heading=${createCloseHeading(this.hass, this._params.title)}
+      >
+        <!-- Dialog content -->
+        <ha-button @click=${this.closeDialog} slot="secondaryAction">
+          ${this.hass.localize("ui.common.cancel")}
+        </ha-button>
+        <ha-button @click=${this._submit} slot="primaryAction">
+          ${this.hass.localize("ui.common.save")}
+        </ha-button>
+      </ha-dialog>
+    `;
+  }
+
+  static styles = [haStyleDialog, css``];
+}
+```
+
+### Dialog Design Guidelines
+
+- Max width: 560px (Alert/confirmation: 320px fixed width)
+- Close X-icon on top left (all screen sizes)
+- Submit button grouped with cancel at bottom right
+- Keep button labels short: "Save", "Delete", "Enable"
+- Destructive actions use red warning button
+- Always use a title (best practice)
+- Strive for minimalism
+
+#### 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
+
+### 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
+
+- **"add-on"** (hyphenated, not "addon")
+- **"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
+
