+Suggested comment for [Issue #49](https://github.com/sickn33/antigravity-awesome-skills/issues/49). Paste this on the issue:
+
+---
+
+The 404 happens because the package wasn’t published to npm yet. We’ve addressed it in two ways:
+
+1. **Publish to npm** – We’re set up to publish so `npx antigravity-awesome-skills` will work after the first release. You can also trigger a manual publish via the “Publish to npm” workflow (Actions tab) if you have `NPM_TOKEN` configured.
+
+2. **Fallback** – Until then (or if you hit a 404 for any reason), use:
+   ```bash
+   npx github:sickn33/antigravity-awesome-skills
+   ```
+   The README, GETTING_STARTED, and FAQ now mention this fallback.
+
+Thanks for reporting.

+    - Update version header in `README.md` if it displays the number.
+    - One-liner: `npm version patch` (or `minor`/`major`) — bumps `package.json` and creates a git tag; then amend if you need to tag after release.

+## Local development setup
+
+To run validation, index generation, and README updates locally:
+
+1. **Node.js** (for catalog and installer): `npm ci`
+2. **Python 3** (for validate, index, readme scripts): install dependencies with
+   ```bash
+   pip install -r requirements.txt
+   ```
+   Then you can run `npm run chain` (validate → index → readme) and `npm run catalog`.
+
+**Validation:** The canonical validator is **Python** (`scripts/validate_skills.py`). Use `npm run validate` (or `npm run validate:strict` for CI-style checks). The JavaScript validator (`scripts/validate-skills.js`) is legacy/optional and uses a different schema; CI and PR checks rely on the Python validator only.
+
+**npm audit:** CI runs `npm audit --audit-level=high`. To fix issues locally: run `npm audit`, then `npm update` or `npm audit fix` as appropriate; for breaking changes, update dependencies manually and run tests.

-# Release v4.5.0: Stitch UI Design
-
-> **Expert prompting guide for Google Stitch AI-powered UI design tool**
-
-This release adds the stitch-ui-design skill and clarifies documentation around Starter Packs vs full repo installation, bringing the total to 625 skills. The new skill provides comprehensive guidance for creating effective prompts in Google Stitch (Gemini 2.5 Flash) to generate high-quality UI designs for web and mobile applications.
-
-## New Skills (1)
-
-- **[stitch-ui-design](skills/stitch-ui-design/)** – Expert guide for creating effective prompts for Google Stitch AI UI design tool. Covers prompt structure, specificity techniques, iteration strategies, design-to-code workflows, and 10+ practical examples for landing pages, mobile apps, and dashboards.
-
-> **Try it:** `Use @stitch-ui-design to help me create a prompt for a mobile fitness app dashboard`
-
-## Documentation Improvements
-
-- **Clarified Starter Packs**: Updated README.md and GETTING_STARTED.md to explicitly state that installation means cloning the full repo once; Starter Packs are curated lists to help discover which skills to use by role, not a different installation method (fixes [#44](https://github.com/sickn33/antigravity-awesome-skills/issues/44))
-

+
+# Angular Best Practices
+
+Comprehensive performance optimization guide for Angular applications. Contains prioritized rules for eliminating performance bottlenecks, optimizing bundles, and improving rendering.
+
+## When to Apply
+
+Reference these guidelines when:
+
+- Writing new Angular components or pages
+- Implementing data fetching patterns
+- Reviewing code for performance issues
+- Refactoring existing Angular code
+- Optimizing bundle size or load times
+- Configuring SSR/hydration
+
+---
+
+## Rule Categories by Priority
+
+| Priority | Category              | Impact     | Focus                           |
+| -------- | --------------------- | ---------- | ------------------------------- |
+| 1        | Change Detection      | CRITICAL   | Signals, OnPush, Zoneless       |
+| 2        | Async Waterfalls      | CRITICAL   | RxJS patterns, SSR preloading   |
+| 3        | Bundle Optimization   | CRITICAL   | Lazy loading, tree shaking      |
+| 4        | Rendering Performance | HIGH       | @defer, trackBy, virtualization |
+| 5        | Server-Side Rendering | HIGH       | Hydration, prerendering         |
+| 6        | Template Optimization | MEDIUM     | Control flow, pipes             |
+| 7        | State Management      | MEDIUM     | Signal patterns, selectors      |
+| 8        | Memory Management     | LOW-MEDIUM | Cleanup, subscriptions          |
+
+---
+
+## 1. Change Detection (CRITICAL)
+
+### Use OnPush Change Detection
+
+```typescript
+// CORRECT - OnPush with Signals
+@Component({
+  changeDetection: ChangeDetectionStrategy.OnPush,
+  template: `<div>{{ count() }}</div>`,
+})
+export class CounterComponent {
+  count = signal(0);
+}
+
+// WRONG - Default change detection
+@Component({
+  template: `<div>{{ count }}</div>`, // Checked every cycle
+})
+export class CounterComponent {
+  count = 0;
+}
+```
+
+### Prefer Signals Over Mutable Properties
+
+```typescript
+// CORRECT - Signals trigger precise updates
+@Component({
+  template: `
+    <h1>{{ title() }}</h1>
+    <p>Count: {{ count() }}</p>
+  `,
+})
+export class DashboardComponent {
+  title = signal("Dashboard");
+  count = signal(0);
+}
+
+// WRONG - Mutable properties require zone.js checks
+@Component({
+  template: `
+    <h1>{{ title }}</h1>
+    <p>Count: {{ count }}</p>
+  `,
+})
+export class DashboardComponent {
+  title = "Dashboard";
+  count = 0;
+}
+```
+
+### Enable Zoneless for New Projects
+
+```typescript
+// main.ts - Zoneless Angular (v20+)
+bootstrapApplication(AppComponent, {
+  providers: [provideZonelessChangeDetection()],
+});
+```
+
+**Benefits:**
+
+- No zone.js patches on async APIs
+- Smaller bundle (~15KB savings)
+- Clean stack traces for debugging
+- Better micro-frontend compatibility
+
+---
+
+## 2. Async Operations & Waterfalls (CRITICAL)
+
+### Eliminate Sequential Data Fetching
+
+```typescript
+// WRONG - Nested subscriptions create waterfalls
+this.route.params.subscribe((params) => {
+  // 1. Wait for params
+  this.userService.getUser(params.id).subscribe((user) => {
+    // 2. Wait for user
+    this.postsService.getPosts(user.id).subscribe((posts) => {
+      // 3. Wait for posts
+    });
+  });
+});
+
+// CORRECT - Parallel execution with forkJoin
+forkJoin({
+  user: this.userService.getUser(id),
+  posts: this.postsService.getPosts(id),
+}).subscribe((data) => {
+  // Fetched in parallel
+});
+
+// CORRECT - Flatten dependent calls with switchMap
+this.route.params
+  .pipe(
+    map((p) => p.id),
+    switchMap((id) => this.userService.getUser(id)),
+  )
+  .subscribe();
+```
+
+### Avoid Client-Side Waterfalls in SSR
+
+```typescript
+// CORRECT - Use resolvers or blocking hydration for critical data
+export const route: Route = {
+  path: "profile/:id",
+  resolve: { data: profileResolver }, // Fetched on server before navigation
+  component: ProfileComponent,
+};
+
+// WRONG - Component fetches data on init
+class ProfileComponent implements OnInit {
+  ngOnInit() {
+    // Starts ONLY after JS loads and component renders
+    this.http.get("/api/profile").subscribe();
+  }
+}
+```
+
+---
+
+## 3. Bundle Optimization (CRITICAL)
+
+### Lazy Load Routes
+
+```typescript
+// CORRECT - Lazy load feature routes
+export const routes: Routes = [
+  {
+    path: "admin",
+    loadChildren: () =>
+      import("./admin/admin.routes").then((m) => m.ADMIN_ROUTES),
+  },
+  {
+    path: "dashboard",
+    loadComponent: () =>
+      import("./dashboard/dashboard.component").then(
+        (m) => m.DashboardComponent,
+      ),
+  },
+];
+
+// WRONG - Eager loading everything
+import { AdminModule } from "./admin/admin.module";
+export const routes: Routes = [
+  { path: "admin", component: AdminComponent }, // In main bundle
+];
+```
+
+### Use @defer for Heavy Components
+
+```html
+<!-- CORRECT - Heavy component loads on demand -->
+@defer (on viewport) {
+<app-analytics-chart [data]="data()" />
+} @placeholder {
+<div class="chart-skeleton"></div>
+}
+
+<!-- WRONG - Heavy component in initial bundle -->
+<app-analytics-chart [data]="data()" />
+```
+
+### Avoid Barrel File Re-exports
+
+```typescript
+// WRONG - Imports entire barrel, breaks tree-shaking
+import { Button, Modal, Table } from "@shared/components";
+
+// CORRECT - Direct imports
+import { Button } from "@shared/components/button/button.component";
+import { Modal } from "@shared/components/modal/modal.component";
+```
+
+### Dynamic Import Third-Party Libraries
+
+```typescript
+// CORRECT - Load heavy library on demand
+async loadChart() {
+  const { Chart } = await import('chart.js');
+  this.chart = new Chart(this.canvas, config);
+}
+
+// WRONG - Bundle Chart.js in main chunk
+import { Chart } from 'chart.js';
+```
+
+---
+
+## 4. Rendering Performance (HIGH)
+
+### Always Use trackBy with @for
+
+```html
+<!-- CORRECT - Efficient DOM updates -->
+@for (item of items(); track item.id) {
+<app-item-card [item]="item" />
+}
+
+<!-- WRONG - Entire list re-renders on any change -->
+@for (item of items(); track $index) {
+<app-item-card [item]="item" />
+}
+```
+
+### Use Virtual Scrolling for Large Lists
+
+```typescript
+import { CdkVirtualScrollViewport, CdkFixedSizeVirtualScroll } from '@angular/cdk/scrolling';
+
+@Component({
+  imports: [CdkVirtualScrollViewport, CdkFixedSizeVirtualScroll],
+  template: `
+    <cdk-virtual-scroll-viewport itemSize="50" class="viewport">
+      <div *cdkVirtualFor="let item of items" class="item">
+        {{ item.name }}
+      </div>
+    </cdk-virtual-scroll-viewport>
+  `
+})
+```
+
+### Prefer Pure Pipes Over Methods
+
+```typescript
+// CORRECT - Pure pipe, memoized
+@Pipe({ name: 'filterActive', standalone: true, pure: true })
+export class FilterActivePipe implements PipeTransform {
+  transform(items: Item[]): Item[] {
+    return items.filter(i => i.active);
+  }
+}
+
+// Template
+@for (item of items() | filterActive; track item.id) { ... }
+
+// WRONG - Method called every change detection
+@for (item of getActiveItems(); track item.id) { ... }
+```
+
+### Use computed() for Derived Data
+
+```typescript
+// CORRECT - Computed, cached until dependencies change
+export class ProductStore {
+  products = signal<Product[]>([]);
+  filter = signal('');
+
+  filteredProducts = computed(() => {
+    const f = this.filter().toLowerCase();
+    return this.products().filter(p =>
+      p.name.toLowerCase().includes(f)
+    );
+  });
+}
+
+// WRONG - Recalculates every access
+get filteredProducts() {
+  return this.products.filter(p =>
+    p.name.toLowerCase().includes(this.filter)
+  );
+}
+```
+
+---
+
+## 5. Server-Side Rendering (HIGH)
+
+### Configure Incremental Hydration
+
+```typescript
+// app.config.ts
+import {
+  provideClientHydration,
+  withIncrementalHydration,
+} from "@angular/platform-browser";
+
+export const appConfig: ApplicationConfig = {
+  providers: [
+    provideClientHydration(withIncrementalHydration(), withEventReplay()),
+  ],
+};
+```
+
+### Defer Non-Critical Content
+
+```html
+<!-- Critical above-the-fold content -->
+<app-header />
+<app-hero />
+
+<!-- Below-fold deferred with hydration triggers -->
+@defer (hydrate on viewport) {
+<app-product-grid />
+} @defer (hydrate on interaction) {
+<app-chat-widget />
+}
+```
+
+### Use TransferState for SSR Data
+
+```typescript
+@Injectable({ providedIn: "root" })
+export class DataService {
+  private http = inject(HttpClient);
+  private transferState = inject(TransferState);
+  private platformId = inject(PLATFORM_ID);
+
+  getData(key: string): Observable<Data> {
+    const stateKey = makeStateKey<Data>(key);
+
+    if (isPlatformBrowser(this.platformId)) {
+      const cached = this.transferState.get(stateKey, null);
+      if (cached) {
+        this.transferState.remove(stateKey);
+        return of(cached);
+      }
+    }
+
+    return this.http.get<Data>(`/api/${key}`).pipe(
+      tap((data) => {
+        if (isPlatformServer(this.platformId)) {
+          this.transferState.set(stateKey, data);
+        }
+      }),
+    );
+  }
+}
+```
+
+---
+
+## 6. Template Optimization (MEDIUM)
+
+### Use New Control Flow Syntax
+
+```html
+<!-- CORRECT - New control flow (faster, smaller bundle) -->
+@if (user()) {
+<span>{{ user()!.name }}</span>
+} @else {
+<span>Guest</span>
+} @for (item of items(); track item.id) {
+<app-item [item]="item" />
+} @empty {
+<p>No items</p>
+}
+
+<!-- WRONG - Legacy structural directives -->
+<span *ngIf="user; else guest">{{ user.name }}</span>
+<ng-template #guest><span>Guest</span></ng-template>
+```
+
+### Avoid Complex Template Expressions
+
+```typescript
+// CORRECT - Precompute in component
+class Component {
+  items = signal<Item[]>([]);
+  sortedItems = computed(() =>
+    [...this.items()].sort((a, b) => a.name.localeCompare(b.name))
+  );
+}
+
+// Template
+@for (item of sortedItems(); track item.id) { ... }
+
+// WRONG - Sorting in template every render
+@for (item of items() | sort:'name'; track item.id) { ... }
+```
+
+---
+
+## 7. State Management (MEDIUM)
+
+### Use Selectors to Prevent Re-renders
+
+```typescript
+// CORRECT - Selective subscription
+@Component({
+  template: `<span>{{ userName() }}</span>`,
+})
+class HeaderComponent {
+  private store = inject(Store);
+  // Only re-renders when userName changes
+  userName = this.store.selectSignal(selectUserName);
+}
+
+// WRONG - Subscribing to entire state
+@Component({
+  template: `<span>{{ state().user.name }}</span>`,
+})
+class HeaderComponent {
+  private store = inject(Store);
+  // Re-renders on ANY state change
+  state = toSignal(this.store);
+}
+```
+
+### Colocate State with Features
+
+```typescript
+// CORRECT - Feature-scoped store
+@Injectable() // NOT providedIn: 'root'
+export class ProductStore { ... }
+
+@Component({
+  providers: [ProductStore], // Scoped to component tree
+})
+export class ProductPageComponent {
+  store = inject(ProductStore);
+}
+
+// WRONG - Everything in global store
+@Injectable({ providedIn: 'root' })
+export class GlobalStore {
+  // Contains ALL app state - hard to tree-shake
+}
+```
+
+---
+
+## 8. Memory Management (LOW-MEDIUM)
+
+### Use takeUntilDestroyed for Subscriptions
+
+```typescript
+import { takeUntilDestroyed } from '@angular/core/rxjs-interop';
+
+@Component({...})
+export class DataComponent {
+  private destroyRef = inject(DestroyRef);
+
+  constructor() {
+    this.data$.pipe(
+      takeUntilDestroyed(this.destroyRef)
+    ).subscribe(data => this.process(data));
+  }
+}
+
+// WRONG - Manual subscription management
+export class DataComponent implements OnDestroy {
+  private subscription!: Subscription;
+
+  ngOnInit() {
+    this.subscription = this.data$.subscribe(...);
+  }
+
+  ngOnDestroy() {
+    this.subscription.unsubscribe(); // Easy to forget
+  }
+}
+```
+
+### Prefer Signals Over Subscriptions
+
+```typescript
+// CORRECT - No subscription needed
+@Component({
+  template: `<div>{{ data().name }}</div>`,
+})
+export class Component {
+  data = toSignal(this.service.data$, { initialValue: null });
+}
+
+// WRONG - Manual subscription
+@Component({
+  template: `<div>{{ data?.name }}</div>`,
+})
+export class Component implements OnInit, OnDestroy {
+  data: Data | null = null;
+  private sub!: Subscription;
+
+  ngOnInit() {
+    this.sub = this.service.data$.subscribe((d) => (this.data = d));
+  }
+
+  ngOnDestroy() {
+    this.sub.unsubscribe();
+  }
+}
+```
+
+---
+
+## Quick Reference Checklist
+
+### New Component
+

+- [ ] `standalone: true`
+- [ ] Signals for state (`signal()`, `input()`, `output()`)
+- [ ] `inject()` for dependencies
+- [ ] `@for` with `track` expression
+
+### Performance Review
+
+- [ ] No methods in templates (use pipes or computed)
+- [ ] Large lists virtualized
+- [ ] Heavy components deferred
+- [ ] Routes lazy-loaded
+- [ ] Third-party libs dynamically imported
+
+### SSR Check
+
+- [ ] Hydration configured

+
+# Angular State Management
+
+Comprehensive guide to modern Angular state management patterns, from Signal-based local state to global stores and server state synchronization.
+
+## When to Use This Skill
+
+- Setting up global state management in Angular
+- Choosing between Signals, NgRx, or Akita
+- Managing component-level stores
+- Implementing optimistic updates
+- Debugging state-related issues
+- Migrating from legacy state patterns
+
+## Do Not Use This Skill When
+
+- The task is unrelated to Angular state management
+- You need React state management → use `react-state-management`
+
+---
+
+## Core Concepts
+
+### State Categories
+
+| Type             | Description                  | Solutions             |
+| ---------------- | ---------------------------- | --------------------- |
+| **Local State**  | Component-specific, UI state | Signals, `signal()`   |
+| **Shared State** | Between related components   | Signal services       |
+| **Global State** | App-wide, complex            | NgRx, Akita, Elf      |
+| **Server State** | Remote data, caching         | NgRx Query, RxAngular |
+| **URL State**    | Route parameters             | ActivatedRoute        |
+| **Form State**   | Input values, validation     | Reactive Forms        |
+
+### Selection Criteria
+
+```
+Small app, simple state → Signal Services
+Medium app, moderate state → Component Stores
+Large app, complex state → NgRx Store
+Heavy server interaction → NgRx Query + Signal Services
+Real-time updates → RxAngular + Signals
+```
+
+---
+
+## Quick Start: Signal-Based State
+
+### Pattern 1: Simple Signal Service
+
+```typescript
+// services/counter.service.ts
+import { Injectable, signal, computed } from "@angular/core";
+
+@Injectable({ providedIn: "root" })
+export class CounterService {
+  // Private writable signals
+  private _count = signal(0);
+
+  // Public read-only
+  readonly count = this._count.asReadonly();
+  readonly doubled = computed(() => this._count() * 2);
+  readonly isPositive = computed(() => this._count() > 0);
+
+  increment() {
+    this._count.update((v) => v + 1);
+  }
+
+  decrement() {
+    this._count.update((v) => v - 1);
+  }
+
+  reset() {
+    this._count.set(0);
+  }
+}
+
+// Usage in component
+@Component({
+  template: `
+    <p>Count: {{ counter.count() }}</p>
+    <p>Doubled: {{ counter.doubled() }}</p>
+    <button (click)="counter.increment()">+</button>
+  `,
+})
+export class CounterComponent {
+  counter = inject(CounterService);
+}
+```
+
+### Pattern 2: Feature Signal Store
+
+```typescript
+// stores/user.store.ts
+import { Injectable, signal, computed, inject } from "@angular/core";
+import { HttpClient } from "@angular/common/http";
+import { toSignal } from "@angular/core/rxjs-interop";
+
+interface User {
+  id: string;
+  name: string;
+  email: string;
+}
+
+interface UserState {
+  user: User | null;
+  loading: boolean;
+  error: string | null;
+}
+
+@Injectable({ providedIn: "root" })
+export class UserStore {
+  private http = inject(HttpClient);
+
+  // State signals
+  private _user = signal<User | null>(null);
+  private _loading = signal(false);
+  private _error = signal<string | null>(null);
+
+  // Selectors (read-only computed)
+  readonly user = computed(() => this._user());
+  readonly loading = computed(() => this._loading());
+  readonly error = computed(() => this._error());
+  readonly isAuthenticated = computed(() => this._user() !== null);
+  readonly displayName = computed(() => this._user()?.name ?? "Guest");
+
+  // Actions
+  async loadUser(id: string) {
+    this._loading.set(true);
+    this._error.set(null);
+
+    try {
+      const user = await fetch(`/api/users/${id}`).then((r) => r.json());
+      this._user.set(user);
+    } catch (e) {
+      this._error.set("Failed to load user");
+    } finally {
+      this._loading.set(false);
+    }
+  }
+
+  updateUser(updates: Partial<User>) {
+    this._user.update((user) => (user ? { ...user, ...updates } : null));
+  }
+
+  logout() {
+    this._user.set(null);
+    this._error.set(null);
+  }
+}
+```
+
+### Pattern 3: SignalStore (NgRx Signals)
+
+```typescript
+// stores/products.store.ts
+import {
+  signalStore,
+  withState,
+  withMethods,
+  withComputed,
+  patchState,
+} from "@ngrx/signals";
+import { inject } from "@angular/core";
+import { ProductService } from "./product.service";
+

+      }));
+    },
+  })),
+);
+
+// Usage

+
+## NgRx Store (Global State)
+
+### Setup
+
+```typescript
+// store/app.state.ts
+import { ActionReducerMap } from "@ngrx/store";
+
+export interface AppState {
+  user: UserState;
+  cart: CartState;
+}
+
+export const reducers: ActionReducerMap<AppState> = {
+  user: userReducer,
+  cart: cartReducer,
+};
+
+// main.ts
+bootstrapApplication(AppComponent, {
+  providers: [
+    provideStore(reducers),
+    provideEffects([UserEffects, CartEffects]),
+    provideStoreDevtools({ maxAge: 25 }),
+  ],
+});
+```
+
+### Feature Slice Pattern
+
+```typescript
+// store/user/user.actions.ts
+import { createActionGroup, props, emptyProps } from "@ngrx/store";
+
+export const UserActions = createActionGroup({
+  source: "User",
+  events: {
+    "Load User": props<{ userId: string }>(),
+    "Load User Success": props<{ user: User }>(),
+    "Load User Failure": props<{ error: string }>(),
+    "Update User": props<{ updates: Partial<User> }>(),
+    Logout: emptyProps(),
+  },
+});
+```
+
+```typescript
+// store/user/user.reducer.ts
+import { createReducer, on } from "@ngrx/store";
+import { UserActions } from "./user.actions";
+
+export interface UserState {
+  user: User | null;
+  loading: boolean;
+  error: string | null;
+}
+
+const initialState: UserState = {
+  user: null,
+  loading: false,
+  error: null,
+};
+
+export const userReducer = createReducer(
+  initialState,
+
+  on(UserActions.loadUser, (state) => ({
+    ...state,
+    loading: true,
+    error: null,
+  })),
+
+  on(UserActions.loadUserSuccess, (state, { user }) => ({
+    ...state,
+    user,
+    loading: false,
+  })),
+
+  on(UserActions.loadUserFailure, (state, { error }) => ({
+    ...state,
+    loading: false,
+    error,
+  })),
+
+  on(UserActions.logout, () => initialState),
+);
+```
+
+```typescript
+// store/user/user.selectors.ts
+import { createFeatureSelector, createSelector } from "@ngrx/store";
+import { UserState } from "./user.reducer";
+
+export const selectUserState = createFeatureSelector<UserState>("user");
+
+export const selectUser = createSelector(
+  selectUserState,
+  (state) => state.user,
+);
+
+export const selectUserLoading = createSelector(
+  selectUserState,
+  (state) => state.loading,
+);
+
+export const selectIsAuthenticated = createSelector(
+  selectUser,
+  (user) => user !== null,
+);
+```
+
+```typescript
+// store/user/user.effects.ts
+import { Injectable, inject } from "@angular/core";
+import { Actions, createEffect, ofType } from "@ngrx/effects";
+import { switchMap, map, catchError, of } from "rxjs";
+
+@Injectable()
+export class UserEffects {
+  private actions$ = inject(Actions);
+  private userService = inject(UserService);
+
+  loadUser$ = createEffect(() =>
+    this.actions$.pipe(
+      ofType(UserActions.loadUser),
+      switchMap(({ userId }) =>
+        this.userService.getUser(userId).pipe(
+          map((user) => UserActions.loadUserSuccess({ user })),
+          catchError((error) =>
+            of(UserActions.loadUserFailure({ error: error.message })),
+          ),
+        ),
+      ),
+    ),
+  );
+}
+```
+
+### Component Usage
+
+```typescript
+@Component({
+  template: `
+    @if (loading()) {
+      <app-spinner />
+    } @else if (user(); as user) {
+      <h1>Welcome, {{ user.name }}</h1>
+      <button (click)="logout()">Logout</button>
+    }
+  `,
+})
+export class HeaderComponent {
+  private store = inject(Store);
+
+  user = this.store.selectSignal(selectUser);
+  loading = this.store.selectSignal(selectUserLoading);
+
+  logout() {
+    this.store.dispatch(UserActions.logout());
+  }
+}
+```
+
+---
+
+## RxJS-Based Patterns
+
+### Component Store (Local Feature State)
+
+```typescript
+// stores/todo.store.ts
+import { Injectable } from "@angular/core";
+import { ComponentStore } from "@ngrx/component-store";
+import { switchMap, tap, catchError, EMPTY } from "rxjs";
+
+interface TodoState {
+  todos: Todo[];
+  loading: boolean;
+}
+
+@Injectable()
+export class TodoStore extends ComponentStore<TodoState> {
+  constructor(private todoService: TodoService) {
+    super({ todos: [], loading: false });
+  }
+
+  // Selectors
+  readonly todos$ = this.select((state) => state.todos);
+  readonly loading$ = this.select((state) => state.loading);
+  readonly completedCount$ = this.select(
+    this.todos$,
+    (todos) => todos.filter((t) => t.completed).length,
+  );
+
+  // Updaters
+  readonly addTodo = this.updater((state, todo: Todo) => ({
+    ...state,
+    todos: [...state.todos, todo],
+  }));
+
+  readonly toggleTodo = this.updater((state, id: string) => ({
+    ...state,
+    todos: state.todos.map((t) =>
+      t.id === id ? { ...t, completed: !t.completed } : t,
+    ),
+  }));
+
+  // Effects
+  readonly loadTodos = this.effect<void>((trigger$) =>
+    trigger$.pipe(
+      tap(() => this.patchState({ loading: true })),
+      switchMap(() =>
+        this.todoService.getAll().pipe(
+          tap({
+            next: (todos) => this.patchState({ todos, loading: false }),
+            error: () => this.patchState({ loading: false }),
+          }),
+          catchError(() => EMPTY),
+        ),
+      ),
+    ),
+  );
+}
+```
+
+---
+
+## Server State with Signals
+
+### HTTP + Signals Pattern
+
+```typescript
+// services/api.service.ts
+import { Injectable, signal, inject } from "@angular/core";
+import { HttpClient } from "@angular/common/http";
+import { toSignal } from "@angular/core/rxjs-interop";
+
+interface ApiState<T> {
+  data: T | null;
+  loading: boolean;
+  error: string | null;
+}
+
+@Injectable({ providedIn: "root" })
+export class ProductApiService {
+  private http = inject(HttpClient);
+
+  private _state = signal<ApiState<Product[]>>({
+    data: null,
+    loading: false,
+    error: null,
+  });
+
+  readonly products = computed(() => this._state().data ?? []);
+  readonly loading = computed(() => this._state().loading);
+  readonly error = computed(() => this._state().error);
+
+  async fetchProducts(): Promise<void> {
+    this._state.update((s) => ({ ...s, loading: true, error: null }));
+
+    try {
+      const data = await firstValueFrom(
+        this.http.get<Product[]>("/api/products"),
+      );
+      this._state.update((s) => ({ ...s, data, loading: false }));
+    } catch (e) {
+      this._state.update((s) => ({
+        ...s,
+        loading: false,
+        error: "Failed to fetch products",
+      }));
+    }
+  }
+
+  // Optimistic update
+  async deleteProduct(id: string): Promise<void> {
+    const previousData = this._state().data;
+
+    // Optimistically remove
+    this._state.update((s) => ({
+      ...s,
+      data: s.data?.filter((p) => p.id !== id) ?? null,
+    }));
+
+    try {
+      await firstValueFrom(this.http.delete(`/api/products/${id}`));
+    } catch {
+      // Rollback on error
+      this._state.update((s) => ({ ...s, data: previousData }));
+    }
+  }
+}
+```

+
+## Best Practices
+
+### Do's
+
+| Practice                           | Why                                |
+| ---------------------------------- | ---------------------------------- |
+| Use Signals for local state        | Simple, reactive, no subscriptions |
+| Use `computed()` for derived data  | Auto-updates, memoized             |
+| Colocate state with feature        | Easier to maintain                 |
+| Use NgRx for complex flows         | Actions, effects, devtools         |
+| Prefer `inject()` over constructor | Cleaner, works in factories        |
+
+### Don'ts
+
+| Anti-Pattern                      | Instead                                               |
+| --------------------------------- | ----------------------------------------------------- |
+| Store derived data                | Use `computed()`                                      |
+| Mutate signals directly           | Use `set()` or `update()`                             |
+| Over-globalize state              | Keep local when possible                              |
+| Mix RxJS and Signals chaotically  | Choose primary, bridge with `toSignal`/`toObservable` |
+| Subscribe in components for state | Use template with signals                             |
+
+---
+
+## Migration Path
+
+### From BehaviorSubject to Signals
+
+```typescript
+// Before: RxJS-based
+@Injectable({ providedIn: "root" })
+export class OldUserService {
+  private userSubject = new BehaviorSubject<User | null>(null);
+  user$ = this.userSubject.asObservable();
+
+  setUser(user: User) {
+    this.userSubject.next(user);
+  }
+}
+
+// After: Signal-based
+@Injectable({ providedIn: "root" })
+export class UserService {
+  private _user = signal<User | null>(null);
+  readonly user = this._user.asReadonly();
+
+  setUser(user: User) {
+    this._user.set(user);
+  }
+}
+```
+
+### Bridging Signals and RxJS
+
+```typescript
+import { toSignal, toObservable } from '@angular/core/rxjs-interop';
+
+// Observable → Signal
+@Component({...})
+export class ExampleComponent {
+  private route = inject(ActivatedRoute);
+
+  // Convert Observable to Signal
+  userId = toSignal(
+    this.route.params.pipe(map(p => p['id'])),
+    { initialValue: '' }
+  );
+}
+
+// Signal → Observable
+export class DataService {
+  private filter = signal('');
+
+  // Convert Signal to Observable
+  filter$ = toObservable(this.filter);
+
+  filteredData$ = this.filter$.pipe(
+    debounceTime(300),
+    switchMap(filter => this.http.get(`/api/data?q=${filter}`))
+  );
+}
+```

+description: Modern Angular UI patterns for loading states, error handling, and data display. Use when building UI components, handling async data, or managing component states.
+risk: safe
+source: self
+---
+
+# Angular UI Patterns
+
+## Core Principles
+
+1. **Never show stale UI** - Loading states only when actually loading
+2. **Always surface errors** - Users must know when something fails
+3. **Optimistic updates** - Make the UI feel instant
+4. **Progressive disclosure** - Use `@defer` to show content as available
+5. **Graceful degradation** - Partial data is better than no data
+
+---
+
+## Loading State Patterns
+
+### The Golden Rule
+
+**Show loading indicator ONLY when there's no data to display.**
+
+```typescript
+@Component({
+  template: `
+    @if (error()) {
+      <app-error-state [error]="error()" (retry)="load()" />
+    } @else if (loading() && !items().length) {
+      <app-skeleton-list />
+    } @else if (!items().length) {
+      <app-empty-state message="No items found" />
+    } @else {
+      <app-item-list [items]="items()" />
+    }
+  `,
+})
+export class ItemListComponent {
+  private store = inject(ItemStore);
+
+  items = this.store.items;
+  loading = this.store.loading;
+  error = this.store.error;
+}
+```
+
+### Loading State Decision Tree
+
+```
+Is there an error?
+  → Yes: Show error state with retry option
+  → No: Continue
+
+Is it loading AND we have no data?
+  → Yes: Show loading indicator (spinner/skeleton)
+  → No: Continue
+
+Do we have data?
+  → Yes, with items: Show the data
+  → Yes, but empty: Show empty state
+  → No: Show loading (fallback)
+```
+
+### Skeleton vs Spinner
+
+| Use Skeleton When    | Use Spinner When      |
+| -------------------- | --------------------- |
+| Known content shape  | Unknown content shape |
+| List/card layouts    | Modal actions         |
+| Initial page load    | Button submissions    |
+| Content placeholders | Inline operations     |
+
+---
+
+## Control Flow Patterns
+
+### @if/@else for Conditional Rendering
+
+```html
+@if (user(); as user) {
+<span>Welcome, {{ user.name }}</span>
+} @else if (loading()) {
+<app-spinner size="small" />
+} @else {
+<a routerLink="/login">Sign In</a>
+}
+```
+
+### @for with Track
+
+```html
+@for (item of items(); track item.id) {
+<app-item-card [item]="item" (delete)="remove(item.id)" />
+} @empty {
+<app-empty-state
+  icon="inbox"
+  message="No items yet"
+  actionLabel="Create Item"
+  (action)="create()"
+/>
+}
+```
+
+### @defer for Progressive Loading
+
+```html
+<!-- Critical content loads immediately -->
+<app-header />
+<app-hero-section />
+
+<!-- Non-critical content deferred -->
+@defer (on viewport) {
+<app-comments [postId]="postId()" />
+} @placeholder {
+<div class="h-32 bg-gray-100 animate-pulse"></div>
+} @loading (minimum 200ms) {
+<app-spinner />
+} @error {
+<app-error-state message="Failed to load comments" />
+}
+```
+
+---
+
+## Error Handling Patterns
+
+### Error Handling Hierarchy
+
+```
+1. Inline error (field-level) → Form validation errors
+2. Toast notification → Recoverable errors, user can retry
+3. Error banner → Page-level errors, data still partially usable
+4. Full error screen → Unrecoverable, needs user action
+```
+
+### Always Show Errors
+
+**CRITICAL: Never swallow errors silently.**
+
+```typescript
+// CORRECT - Error always surfaced to user
+@Component({...})
+export class CreateItemComponent {
+  private store = inject(ItemStore);
+  private toast = inject(ToastService);
+
+  async create(data: CreateItemDto) {
+    try {
+      await this.store.create(data);
+      this.toast.success('Item created successfully');
+      this.router.navigate(['/items']);
+    } catch (error) {
+      console.error('createItem failed:', error);
+      this.toast.error('Failed to create item. Please try again.');
+    }
+  }
+}
+
+// WRONG - Error silently caught
+async create(data: CreateItemDto) {
+  try {
+    await this.store.create(data);
+  } catch (error) {
+    console.error(error); // User sees nothing!
+  }
+}
+```
+
+### Error State Component Pattern
+
+```typescript
+@Component({
+  selector: "app-error-state",
+  standalone: true,
+  imports: [NgOptimizedImage],
+  template: `
+    <div class="error-state">
+      <img ngSrc="/assets/error-icon.svg" width="64" height="64" alt="" />
+      <h3>{{ title() }}</h3>
+      <p>{{ message() }}</p>
+      @if (retry.observed) {
+        <button (click)="retry.emit()" class="btn-primary">Try Again</button>
+      }
+    </div>
+  `,
+})
+export class ErrorStateComponent {
+  title = input("Something went wrong");
+  message = input("An unexpected error occurred");
+  retry = output<void>();
+}
+```
+
+---
+
+## Button State Patterns
+
+### Button Loading State
+
+```html
+<button
+  (click)="handleSubmit()"
+  [disabled]="isSubmitting() || !form.valid"
+  class="btn-primary"
+>
+  @if (isSubmitting()) {
+  <app-spinner size="small" class="mr-2" />
+  Saving... } @else { Save Changes }
+</button>
+```
+
+### Disable During Operations
+
+**CRITICAL: Always disable triggers during async operations.**
+
+```typescript
+// CORRECT - Button disabled while loading
+@Component({
+  template: `
+    <button
+      [disabled]="saving()"
+      (click)="save()"
+    >
+      @if (saving()) {
+        <app-spinner size="sm" /> Saving...
+      } @else {
+        Save
+      }
+    </button>
+  `
+})
+export class SaveButtonComponent {
+  saving = signal(false);
+
+  async save() {
+    this.saving.set(true);
+    try {
+      await this.service.save();
+    } finally {
+      this.saving.set(false);
+    }
+  }
+}
+
+// WRONG - User can click multiple times
+<button (click)="save()">
+  {{ saving() ? 'Saving...' : 'Save' }}
+</button>
+```
+
+---
+
+## Empty States
+
+### Empty State Requirements
+
+Every list/collection MUST have an empty state:
+
+```html
+@for (item of items(); track item.id) {
+<app-item-card [item]="item" />
+} @empty {
+<app-empty-state
+  icon="folder-open"
+  title="No items yet"
+  description="Create your first item to get started"
+  actionLabel="Create Item"
+  (action)="openCreateDialog()"
+/>
+}
+```
+
+### Contextual Empty States
+
+```typescript
+@Component({
+  selector: "app-empty-state",
+  template: `
+    <div class="empty-state">
+      <span class="icon" [class]="icon()"></span>
+      <h3>{{ title() }}</h3>
+      <p>{{ description() }}</p>
+      @if (actionLabel()) {
+        <button (click)="action.emit()" class="btn-primary">
+          {{ actionLabel() }}
+        </button>
+      }
+    </div>
+  `,
+})
+export class EmptyStateComponent {
+  icon = input("inbox");
+  title = input.required<string>();
+  description = input("");
+  actionLabel = input<string | null>(null);
+  action = output<void>();
+}
+```
+
+---
+
+## Form Patterns
+
+### Form with Loading and Validation
+
+```typescript
+@Component({
+  template: `
+    <form [formGroup]="form" (ngSubmit)="onSubmit()">
+      <div class="form-field">
+        <label for="name">Name</label>
+        <input
+          id="name"
+          formControlName="name"
+          [class.error]="isFieldInvalid('name')"
+        />
+        @if (isFieldInvalid("name")) {
+          <span class="error-text">
+            {{ getFieldError("name") }}
+          </span>
+        }
+      </div>
+
+      <div class="form-field">
+        <label for="email">Email</label>
+        <input id="email" type="email" formControlName="email" />
+        @if (isFieldInvalid("email")) {
+          <span class="error-text">
+            {{ getFieldError("email") }}
+          </span>
+        }
+      </div>
+
+      <button type="submit" [disabled]="form.invalid || submitting()">
+        @if (submitting()) {
+          <app-spinner size="sm" /> Submitting...
+        } @else {
+          Submit
+        }
+      </button>
+    </form>
+  `,
+})
+export class UserFormComponent {
+  private fb = inject(FormBuilder);
+
+  submitting = signal(false);
+
+  form = this.fb.group({
+    name: ["", [Validators.required, Validators.minLength(2)]],
+    email: ["", [Validators.required, Validators.email]],
+  });
+
+  isFieldInvalid(field: string): boolean {
+    const control = this.form.get(field);
+    return control ? control.invalid && control.touched : false;
+  }
+
+  getFieldError(field: string): string {
+    const control = this.form.get(field);
+    if (control?.hasError("required")) return "This field is required";
+    if (control?.hasError("email")) return "Invalid email format";
+    if (control?.hasError("minlength")) return "Too short";
+    return "";
+  }
+
+  async onSubmit() {
+    if (this.form.invalid) return;
+
+    this.submitting.set(true);
+    try {
+      await this.service.submit(this.form.value);
+      this.toast.success("Submitted successfully");
+    } catch {
+      this.toast.error("Submission failed");
+    } finally {
+      this.submitting.set(false);
+    }
+  }
+}
+```

+
+## Dialog/Modal Patterns
+
+### Confirmation Dialog
+
+```typescript
+// dialog.service.ts
+@Injectable({ providedIn: 'root' })
+export class DialogService {
+  private dialog = inject(Dialog); // CDK Dialog or custom
+
+  async confirm(options: {
+    title: string;
+    message: string;
+    confirmText?: string;
+    cancelText?: string;
+  }): Promise<boolean> {
+    const dialogRef = this.dialog.open(ConfirmDialogComponent, {
+      data: options,
+    });
+
+    return await firstValueFrom(dialogRef.closed) ?? false;
+  }
+}
+
+// Usage
+async deleteItem(item: Item) {
+  const confirmed = await this.dialog.confirm({
+    title: 'Delete Item',
+    message: `Are you sure you want to delete "${item.name}"?`,
+    confirmText: 'Delete',
+  });
+
+  if (confirmed) {
+    await this.store.delete(item.id);
+  }
+}
+```
+
+---
+
+## Anti-Patterns
+
+### Loading States
+
+```typescript
+// WRONG - Spinner when data exists (causes flash on refetch)
+@if (loading()) {
+  <app-spinner />
+}
+
+// CORRECT - Only show loading without data
+@if (loading() && !items().length) {
+  <app-spinner />
+}
+```
+
+### Error Handling
+
+```typescript
+// WRONG - Error swallowed
+try {
+  await this.service.save();
+} catch (e) {
+  console.log(e); // User has no idea!
+}
+
+// CORRECT - Error surfaced
+try {
+  await this.service.save();
+} catch (e) {
+  console.error("Save failed:", e);
+  this.toast.error("Failed to save. Please try again.");
+}
+```
+
+### Button States
+
+```html
+<!-- WRONG - Button not disabled during submission -->
+<button (click)="submit()">Submit</button>
+
+<!-- CORRECT - Disabled and shows loading -->
+<button (click)="submit()" [disabled]="loading()">
+  @if (loading()) {
+  <app-spinner size="sm" />
+  } Submit
+</button>
+```
+
+---
+
+## UI State Checklist
+
+Before completing any UI component:
+
+### UI States
+
+- [ ] Error state handled and shown to user
+- [ ] Loading state shown only when no data exists
+- [ ] Empty state provided for collections (`@empty` block)
+- [ ] Buttons disabled during async operations
+- [ ] Buttons show loading indicator when appropriate
+
+### Data & Mutations
+
+- [ ] All async operations have error handling
+- [ ] All user actions have feedback (toast/visual)
+- [ ] Optimistic updates rollback on failure
+
+### Accessibility
+
+- [ ] Loading states announced to screen readers
+- [ ] Error messages linked to form fields
+- [ ] Focus management after state changes
+
+---
+
+## Integration with Other Skills
+
+- **angular-state-management**: Use Signal stores for state
+- **angular**: Apply modern patterns (Signals, @defer)
+- **testing-patterns**: Test all UI states

+## Angular Version Timeline
+
+| Version        | Release | Key Features                                           |
+| -------------- | ------- | ------------------------------------------------------ |
+| **Angular 20** | Q2 2025 | Signals stable, Zoneless stable, Incremental hydration |
+| **Angular 21** | Q4 2025 | Signals-first default, Enhanced SSR                    |
+| **Angular 22** | Q2 2026 | Signal Forms, Selectorless components                  |
+
+---
+
+## 1. Signals: The New Reactive Primitive
+
+Signals are Angular's fine-grained reactivity system, replacing zone.js-based change detection.
+
+### Core Concepts
+
+```typescript
+import { signal, computed, effect } from "@angular/core";
+
+// Writable signal
+const count = signal(0);
+
+// Read value
+console.log(count()); // 0
+
+// Update value
+count.set(5); // Direct set
+count.update((v) => v + 1); // Functional update
+
+// Computed (derived) signal
+const doubled = computed(() => count() * 2);
+
+// Effect (side effects)
+effect(() => {
+  console.log(`Count changed to: ${count()}`);
+});
+```
+
+### Signal-Based Inputs and Outputs
+
+```typescript
+import { Component, input, output, model } from "@angular/core";
+
+@Component({
+  selector: "app-user-card",
+  standalone: true,
+  template: `
+    <div class="card">
+      <h3>{{ name() }}</h3>
+      <span>{{ role() }}</span>
+      <button (click)="select.emit(id())">Select</button>
+    </div>
+  `,
+})
+export class UserCardComponent {
+  // Signal inputs (read-only)
+  id = input.required<string>();
+  name = input.required<string>();
+  role = input<string>("User"); // With default
+
+  // Output
+  select = output<string>();
+
+  // Two-way binding (model)
+  isSelected = model(false);
+}
+
+// Usage:
+// <app-user-card [id]="'123'" [name]="'John'" [(isSelected)]="selected" />
+```
+
+### Signal Queries (ViewChild/ContentChild)
+
+```typescript
+import {
+  Component,
+  viewChild,
+  viewChildren,
+  contentChild,
+} from "@angular/core";
+
+@Component({
+  selector: "app-container",
+  standalone: true,
+  template: `
+    <input #searchInput />
+    <app-item *ngFor="let item of items()" />
+  `,
+})
+export class ContainerComponent {
+  // Signal-based queries
+  searchInput = viewChild<ElementRef>("searchInput");
+  items = viewChildren(ItemComponent);
+  projectedContent = contentChild(HeaderDirective);
+
+  focusSearch() {
+    this.searchInput()?.nativeElement.focus();
+  }
+}
+```
+
+### When to Use Signals vs RxJS
+
+| Use Case                | Signals         | RxJS                             |
+| ----------------------- | --------------- | -------------------------------- |
+| Local component state   | ✅ Preferred    | Overkill                         |
+| Derived/computed values | ✅ `computed()` | `combineLatest` works            |
+| Side effects            | ✅ `effect()`   | `tap` operator                   |
+| HTTP requests           | ❌              | ✅ HttpClient returns Observable |
+| Event streams           | ❌              | ✅ `fromEvent`, operators        |
+| Complex async flows     | ❌              | ✅ `switchMap`, `mergeMap`       |
+
+---
+
+## 2. Standalone Components
+
+Standalone components are self-contained and don't require NgModule declarations.
+
+### Creating Standalone Components
+
+```typescript
+import { Component } from "@angular/core";
+import { CommonModule } from "@angular/common";
+import { RouterLink } from "@angular/router";
+
+@Component({
+  selector: "app-header",
+  standalone: true,
+  imports: [CommonModule, RouterLink], // Direct imports
+  template: `
+    <header>
+      <a routerLink="/">Home</a>
+      <a routerLink="/about">About</a>
+    </header>
+  `,
+})
+export class HeaderComponent {}
+```
+
+### Bootstrapping Without NgModule
+
+```typescript
+// main.ts
+import { bootstrapApplication } from "@angular/platform-browser";
+import { provideRouter } from "@angular/router";
+import { provideHttpClient } from "@angular/common/http";
+import { AppComponent } from "./app/app.component";
+import { routes } from "./app/app.routes";
+
+bootstrapApplication(AppComponent, {
+  providers: [provideRouter(routes), provideHttpClient()],
+});
+```
+
+### Lazy Loading Standalone Components
+
+```typescript
+// app.routes.ts
+import { Routes } from "@angular/router";
+
+export const routes: Routes = [
+  {
+    path: "dashboard",
+    loadComponent: () =>
+      import("./dashboard/dashboard.component").then(
+        (m) => m.DashboardComponent,
+      ),
+  },
+  {
+    path: "admin",
+    loadChildren: () =>
+      import("./admin/admin.routes").then((m) => m.ADMIN_ROUTES),
+  },
+];
+```
+
+---
+
+## 3. Zoneless Angular
+
+Zoneless applications don't use zone.js, improving performance and debugging.
+
+### Enabling Zoneless Mode
+
+```typescript
+// main.ts
+import { bootstrapApplication } from "@angular/platform-browser";
+import { provideZonelessChangeDetection } from "@angular/core";
+import { AppComponent } from "./app/app.component";
+
+bootstrapApplication(AppComponent, {
+  providers: [provideZonelessChangeDetection()],
+});
+```
+
+### Zoneless Component Patterns
+
+```typescript
+import { Component, signal, ChangeDetectionStrategy } from "@angular/core";
+
+@Component({
+  selector: "app-counter",
+  standalone: true,
+  changeDetection: ChangeDetectionStrategy.OnPush,
+  template: `
+    <div>Count: {{ count() }}</div>
+    <button (click)="increment()">+</button>
+  `,
+})
+export class CounterComponent {
+  count = signal(0);
+
+  increment() {
+    this.count.update((v) => v + 1);
+    // No zone.js needed - Signal triggers change detection
+  }
+}
+```
+
+### Key Zoneless Benefits
+
+- **Performance**: No zone.js patches on async APIs
+- **Debugging**: Clean stack traces without zone wrappers
+- **Bundle size**: Smaller without zone.js (~15KB savings)
+- **Interoperability**: Better with Web Components and micro-frontends
+
+---
+
+## 4. Server-Side Rendering & Hydration
+
+### SSR Setup with Angular CLI
+
+```bash
+ng add @angular/ssr
+```
+
+### Hydration Configuration
+
+```typescript
+// app.config.ts
+import { ApplicationConfig } from "@angular/core";
+import {
+  provideClientHydration,
+  withEventReplay,
+} from "@angular/platform-browser";
+
+export const appConfig: ApplicationConfig = {
+  providers: [provideClientHydration(withEventReplay())],
+};
+```
+
+### Incremental Hydration (v20+)
+
+```typescript
+import { Component } from "@angular/core";
+
+@Component({
+  selector: "app-page",
+  standalone: true,
+  template: `
+    <app-hero />
+
+    @defer (hydrate on viewport) {
+      <app-comments />
+    }
+
+    @defer (hydrate on interaction) {
+      <app-chat-widget />
+    }
+  `,
+})
+export class PageComponent {}
+```
+
+### Hydration Triggers
+
+| Trigger          | When to Use                             |
+| ---------------- | --------------------------------------- |
+| `on idle`        | Low-priority, hydrate when browser idle |
+| `on viewport`    | Hydrate when element enters viewport    |
+| `on interaction` | Hydrate on first user interaction       |
+| `on hover`       | Hydrate when user hovers                |
+| `on timer(ms)`   | Hydrate after specified delay           |
+
+---
+
+## 5. Modern Routing Patterns
+
+### Functional Route Guards
+
+```typescript
+// auth.guard.ts
+import { inject } from "@angular/core";
+import { Router, CanActivateFn } from "@angular/router";
+import { AuthService } from "./auth.service";
+
+export const authGuard: CanActivateFn = (route, state) => {
+  const auth = inject(AuthService);
+  const router = inject(Router);
+
+  if (auth.isAuthenticated()) {
+    return true;
+  }
+
+  return router.createUrlTree(["/login"], {
+    queryParams: { returnUrl: state.url },
+  });
+};
+
+// Usage in routes
+export const routes: Routes = [
+  {
+    path: "dashboard",
+    loadComponent: () => import("./dashboard.component"),
+    canActivate: [authGuard],
+  },
+];
+```
+
+### Route-Level Data Resolvers
+
+```typescript
+import { inject } from '@angular/core';
+import { ResolveFn } from '@angular/router';
+import { UserService } from './user.service';
+import { User } from './user.model';
+
+export const userResolver: ResolveFn<User> = (route) => {
+  const userService = inject(UserService);
+  return userService.getUser(route.paramMap.get('id')!);
+};
+
+// In routes
+{
+  path: 'user/:id',
+  loadComponent: () => import('./user.component'),
+  resolve: { user: userResolver }
+}
+
+// In component
+export class UserComponent {
+  private route = inject(ActivatedRoute);
+  user = toSignal(this.route.data.pipe(map(d => d['user'])));
+}
+```
+
+---
+
+## 6. Dependency Injection Patterns
+
+### Modern inject() Function
+
+```typescript
+import { Component, inject } from '@angular/core';
+import { HttpClient } from '@angular/common/http';
+import { UserService } from './user.service';
+
+@Component({...})
+export class UserComponent {
+  // Modern inject() - no constructor needed
+  private http = inject(HttpClient);
+  private userService = inject(UserService);
+
+  // Works in any injection context
+  users = toSignal(this.userService.getUsers());
+}
+```
+
+### Injection Tokens for Configuration
+
+```typescript
+import { InjectionToken, inject } from "@angular/core";
+
+// Define token
+export const API_BASE_URL = new InjectionToken<string>("API_BASE_URL");
+
+// Provide in config
+bootstrapApplication(AppComponent, {
+  providers: [{ provide: API_BASE_URL, useValue: "https://api.example.com" }],
+});
+
+// Inject in service
+@Injectable({ providedIn: "root" })
+export class ApiService {
+  private baseUrl = inject(API_BASE_URL);
+
+  get(endpoint: string) {
+    return this.http.get(`${this.baseUrl}/${endpoint}`);
+  }
+}
+```
+
+---
+
+## 7. Component Composition & Reusability
+
+### Content Projection (Slots)
+
+```typescript
+@Component({
+  selector: 'app-card',
+  template: `
+    <div class="card">
+      <div class="header">
+        <!-- Select by attribute -->
+        <ng-content select="[card-header]"></ng-content>
+      </div>
+      <div class="body">
+        <!-- Default slot -->
+        <ng-content></ng-content>
+      </div>
+    </div>
+  `
+})
+export class CardComponent {}
+
+// Usage
+<app-card>
+  <h3 card-header>Title</h3>
+  <p>Body content</p>
+</app-card>
+```
+
+### Host Directives (Composition)
+
+```typescript
+// Reusable behaviors without inheritance
+@Directive({
+  standalone: true,
+  selector: '[appTooltip]',
+  inputs: ['tooltip'] // Signal input alias
+})
+export class TooltipDirective { ... }
+
+@Component({
+  selector: 'app-button',
+  standalone: true,
+  hostDirectives: [
+    {
+      directive: TooltipDirective,
+      inputs: ['tooltip: title'] // Map input
+    }
+  ],
+  template: `<ng-content />`
+})
+export class ButtonComponent {}
+```
+
+---
+
+## 8. State Management Patterns
+
+### Signal-Based State Service
+
+```typescript
+import { Injectable, signal, computed } from "@angular/core";
+
+interface AppState {
+  user: User | null;
+  theme: "light" | "dark";
+  notifications: Notification[];
+}
+
+@Injectable({ providedIn: "root" })
+export class StateService {
+  // Private writable signals
+  private _user = signal<User | null>(null);
+  private _theme = signal<"light" | "dark">("light");
+  private _notifications = signal<Notification[]>([]);
+
+  // Public read-only computed
+  readonly user = computed(() => this._user());
+  readonly theme = computed(() => this._theme());
+  readonly notifications = computed(() => this._notifications());
+  readonly unreadCount = computed(
+    () => this._notifications().filter((n) => !n.read).length,
+  );
+
+  // Actions
+  setUser(user: User | null) {
+    this._user.set(user);
+  }
+
+  toggleTheme() {
+    this._theme.update((t) => (t === "light" ? "dark" : "light"));
+  }
+
+  addNotification(notification: Notification) {
+    this._notifications.update((n) => [...n, notification]);
+  }
+}
+```
+
+### Component Store Pattern with Signals
+
+```typescript
+import { Injectable, signal, computed, inject } from "@angular/core";
+import { HttpClient } from "@angular/common/http";
+import { toSignal } from "@angular/core/rxjs-interop";
+
+@Injectable()
+export class ProductStore {
+  private http = inject(HttpClient);
+
+  // State
+  private _products = signal<Product[]>([]);
+  private _loading = signal(false);
+  private _filter = signal("");
+
+  // Selectors
+  readonly products = computed(() => this._products());
+  readonly loading = computed(() => this._loading());
+  readonly filteredProducts = computed(() => {
+    const filter = this._filter().toLowerCase();
+    return this._products().filter((p) =>
+      p.name.toLowerCase().includes(filter),
+    );
+  });
+
+  // Actions
+  loadProducts() {
+    this._loading.set(true);
+    this.http.get<Product[]>("/api/products").subscribe({
+      next: (products) => {
+        this._products.set(products);
+        this._loading.set(false);
+      },
+      error: () => this._loading.set(false),
+    });
+  }
+
+  setFilter(filter: string) {
+    this._filter.set(filter);
+  }
+}
+```
+
+---
+
+## 9. Forms with Signals (Coming in v22+)
+
+### Current Reactive Forms
+
+```typescript
+import { Component, inject } from "@angular/core";
+import { FormBuilder, Validators, ReactiveFormsModule } from "@angular/forms";
+
+@Component({
+  selector: "app-user-form",
+  standalone: true,
+  imports: [ReactiveFormsModule],
+  template: `
+    <form [formGroup]="form" (ngSubmit)="onSubmit()">
+      <input formControlName="name" placeholder="Name" />
+      <input formControlName="email" type="email" placeholder="Email" />
+      <button [disabled]="form.invalid">Submit</button>
+    </form>
+  `,
+})
+export class UserFormComponent {
+  private fb = inject(FormBuilder);
+
+  form = this.fb.group({
+    name: ["", Validators.required],
+    email: ["", [Validators.required, Validators.email]],
+  });
+
+  onSubmit() {
+    if (this.form.valid) {
+      console.log(this.form.value);
+    }
+  }
+}
+```
+
+### Signal-Aware Form Patterns (Preview)
+
+```typescript
+// Future Signal Forms API (experimental)
+import { Component, signal } from '@angular/core';
+
+@Component({...})
+export class SignalFormComponent {
+  name = signal('');
+  email = signal('');
+
+  // Computed validation
+  isValid = computed(() =>
+    this.name().length > 0 &&
+    this.email().includes('@')
+  );
+
+  submit() {
+    if (this.isValid()) {
+      console.log({ name: this.name(), email: this.email() });
+    }
+  }
+}
+```
+
+---
+
+## 10. Performance Optimization
+
+### Change Detection Strategies
+
+```typescript
+@Component({
+  changeDetection: ChangeDetectionStrategy.OnPush,
+  // Only checks when:
+  // 1. Input signal/reference changes
+  // 2. Event handler runs
+  // 3. Async pipe emits
+  // 4. Signal value changes
+})
+```
+
+### Defer Blocks for Lazy Loading
+
+```typescript
+@Component({
+  template: `
+    <!-- Immediate loading -->
+    <app-header />
+
+    <!-- Lazy load when visible -->
+    @defer (on viewport) {
+      <app-heavy-chart />
+    } @placeholder {
+      <div class="skeleton" />
+    } @loading (minimum 200ms) {
+      <app-spinner />
+    } @error {
+      <p>Failed to load chart</p>
+    }
+  `
+})
+```
+
+### NgOptimizedImage
+
+```typescript
+import { NgOptimizedImage } from '@angular/common';
+
+@Component({
+  imports: [NgOptimizedImage],
+  template: `
+    <img
+      ngSrc="hero.jpg"
+      width="800"
+      height="600"
+      priority
+    />
+
+    <img
+      ngSrc="thumbnail.jpg"
+      width="200"
+      height="150"
+      loading="lazy"
+      placeholder="blur"
+    />
+  `
+})
+```
+
+---
+
+## 11. Testing Modern Angular
+
+### Testing Signal Components
+
+```typescript
+import { ComponentFixture, TestBed } from "@angular/core/testing";
+import { CounterComponent } from "./counter.component";
+
+describe("CounterComponent", () => {
+  let component: CounterComponent;
+  let fixture: ComponentFixture<CounterComponent>;
+
+  beforeEach(async () => {

+      imports: [CounterComponent], // Standalone import
+    }).compileComponents();
+
+    fixture = TestBed.createComponent(CounterComponent);
+    component = fixture.componentInstance;
+    fixture.detectChanges();
+  });
+
+  it("should increment count", () => {
+    expect(component.count()).toBe(0);
+
+    component.increment();
+
+    expect(component.count()).toBe(1);
+  });
+
+  it("should update DOM on signal change", () => {
+    component.count.set(5);
+    fixture.detectChanges();
+
+    const el = fixture.nativeElement.querySelector(".count");
+    expect(el.textContent).toContain("5");
+  });
+});
+```
+
+### Testing with Signal Inputs
+
+```typescript
+import { ComponentFixture, TestBed } from "@angular/core/testing";
+import { ComponentRef } from "@angular/core";
+import { UserCardComponent } from "./user-card.component";
+
+describe("UserCardComponent", () => {
+  let fixture: ComponentFixture<UserCardComponent>;
+  let componentRef: ComponentRef<UserCardComponent>;
+
+  beforeEach(async () => {
+    await TestBed.configureTestingModule({
+      imports: [UserCardComponent],
+    }).compileComponents();
+
+    fixture = TestBed.createComponent(UserCardComponent);
+    componentRef = fixture.componentRef;
+
+    // Set signal inputs via setInput
+    componentRef.setInput("id", "123");
+    componentRef.setInput("name", "John Doe");
+
+    fixture.detectChanges();
+  });
+
+  it("should display user name", () => {
+    const el = fixture.nativeElement.querySelector("h3");
+    expect(el.textContent).toContain("John Doe");
+  });
+});

+description: SOTA Computer Vision Expert (2026). Specialized in YOLO26, Segment Anything 3 (SAM 3), Vision Language Models, and real-time spatial analysis.
+---
+
+# Computer Vision Expert (SOTA 2026)
+
+**Role**: Advanced Vision Systems Architect & Spatial Intelligence Expert
+
+## Purpose
+To provide expert guidance on designing, implementing, and optimizing state-of-the-art computer vision pipelines. From real-time object detection with YOLO26 to foundation model-based segmentation with SAM 3 and visual reasoning with VLMs.
+
+## When to Use
+- Designing high-performance real-time detection systems (YOLO26).
+- Implementing zero-shot or text-guided segmentation tasks (SAM 3).
+- Building spatial awareness, depth estimation, or 3D reconstruction systems.
+- Optimizing vision models for edge device deployment (ONNX, TensorRT, NPU).
+- Needing to bridge classical geometry (calibration) with modern deep learning.
+
+## Capabilities
+
+### 1. Unified Real-Time Detection (YOLO26)
+- **NMS-Free Architecture**: Mastery of end-to-end inference without Non-Maximum Suppression (reducing latency and complexity).
+- **Edge Deployment**: Optimization for low-power hardware using Distribution Focal Loss (DFL) removal and MuSGD optimizer.
+- **Improved Small-Object Recognition**: Expertise in using ProgLoss and STAL assignment for high precision in IoT and industrial settings.
+
+### 2. Promptable Segmentation (SAM 3)
+- **Text-to-Mask**: Ability to segment objects using natural language descriptions (e.g., "the blue container on the right").
+- **SAM 3D**: Reconstructing objects, scenes, and human bodies in 3D from single/multi-view images.
+- **Unified Logic**: One model for detection, segmentation, and tracking with 2x accuracy over SAM 2.
+
+### 3. Vision Language Models (VLMs)
+- **Visual Grounding**: Leveraging Florence-2, PaliGemma 2, or Qwen2-VL for semantic scene understanding.
+- **Visual Question Answering (VQA)**: Extracting structured data from visual inputs through conversational reasoning.
+
+### 4. Geometry & Reconstruction
+- **Depth Anything V2**: State-of-the-art monocular depth estimation for spatial awareness.
+- **Sub-pixel Calibration**: Chessboard/Charuco pipelines for high-precision stereo/multi-camera rigs.
+- **Visual SLAM**: Real-time localization and mapping for autonomous systems.
+
+## Patterns
+
+### 1. Text-Guided Vision Pipelines
+- Use SAM 3's text-to-mask capability to isolate specific parts during inspection without needing custom detectors for every variation.
+- Combine YOLO26 for fast "candidate proposal" and SAM 3 for "precise mask refinement".
+
+### 2. Deployment-First Design
+- Leverage YOLO26's simplified ONNX/TensorRT exports (NMS-free).
+- Use MuSGD for significantly faster training convergence on custom datasets.
+
+### 3. Progressive 3D Scene Reconstruction
+- Integrate monocular depth maps with geometric homographies to build accurate 2.5D/3D representations of scenes.
+
+## Anti-Patterns
+
+- **Manual NMS Post-processing**: Stick to NMS-free architectures (YOLO26/v10+) for lower overhead.
+- **Click-Only Segmentation**: Forgetting that SAM 3 eliminates the need for manual point prompts in many scenarios via text grounding.
+- **Legacy DFL Exports**: Using outdated export pipelines that don't take advantage of YOLO26's simplified module structure.
+
+## Sharp Edges (2026)
+
+| Issue | Severity | Solution |
+|-------|----------|----------|
+| SAM 3 VRAM Usage | Medium | Use quantized/distilled versions for local GPU inference. |
+| Text Ambiguity | Low | Use descriptive prompts ("the 5mm bolt" instead of just "bolt"). |
+| Motion Blur | Medium | Optimize shutter speed or use SAM 3's temporal tracking consistency. |
+| Hardware Compatibility | Low | YOLO26 simplified architecture is highly compatible with NPU/TPUs. |

+
+# Radix UI Design System
+
+Build production-ready, accessible design systems using Radix UI primitives with full customization control and zero style opinions.
+
+## Overview
+
+Radix UI provides unstyled, accessible components (primitives) that you can customize to match any design system. This skill guides you through building scalable component libraries with Radix UI, focusing on accessibility-first design, theming architecture, and composable patterns.
+
+**Key Strengths:**
+- **Headless by design**: Full styling control without fighting defaults
+- **Accessibility built-in**: WAI-ARIA compliant, keyboard navigation, screen reader support
+- **Composable primitives**: Build complex components from simple building blocks
+- **Framework agnostic**: Works with React, but styles work anywhere
+
+## When to Use This Skill
+
+- Creating a custom design system from scratch
+- Building accessible UI component libraries
+- Implementing complex interactive components (Dialog, Dropdown, Tabs, etc.)
+- Migrating from styled component libraries to unstyled primitives
+- Setting up theming systems with CSS variables or Tailwind
+- Need full control over component behavior and styling
+- Building applications requiring WCAG 2.1 AA/AAA compliance
+
+## Do not use this skill when
+
+- You need pre-styled components out of the box (use shadcn/ui, Mantine, etc.)
+- Building simple static pages without interactivity
+- The project doesn't use React 16.8+ (Radix requires hooks)
+- You need components for frameworks other than React
+
+---
+
+## Core Principles
+
+### 1. Accessibility First
+
+Every Radix primitive is built with accessibility as the foundation:
+
+- **Keyboard Navigation**: Full keyboard support (Tab, Arrow keys, Enter, Escape)
+- **Screen Readers**: Proper ARIA attributes and live regions
+- **Focus Management**: Automatic focus trapping and restoration
+- **Disabled States**: Proper handling of disabled and aria-disabled
+
+**Rule**: Never override accessibility features. Enhance, don't replace.
+
+### 2. Headless Architecture
+
+Radix provides **behavior**, you provide **appearance**:
+
+```tsx
+// ❌ Don't fight pre-styled components
+<Button className="override-everything" />
+
+// ✅ Radix gives you behavior, you add styling
+<Dialog.Root>
+  <Dialog.Trigger className="your-button-styles" />
+  <Dialog.Content className="your-modal-styles" />
+</Dialog.Root>
+```
+
+### 3. Composition Over Configuration
+
+Build complex components from simple primitives:
+
+```tsx
+// Primitive components compose naturally
+<Tabs.Root>
+  <Tabs.List>
+    <Tabs.Trigger value="tab1">Tab 1</Tabs.Trigger>
+    <Tabs.Trigger value="tab2">Tab 2</Tabs.Trigger>
+  </Tabs.List>
+  <Tabs.Content value="tab1">Content 1</Tabs.Content>
+  <Tabs.Content value="tab2">Content 2</Tabs.Content>
+</Tabs.Root>
+```
+
+---
+
+## Getting Started
+
+### Installation
+
+```bash
+# Install individual primitives (recommended)
+npm install @radix-ui/react-dialog @radix-ui/react-dropdown-menu
+
+# Or install multiple at once
+npm install @radix-ui/react-{dialog,dropdown-menu,tabs,tooltip}
+
+# For styling (optional but common)
+npm install clsx tailwind-merge class-variance-authority
+```
+
+### Basic Component Pattern
+
+Every Radix component follows this pattern:
+
+```tsx
+import * as Dialog from '@radix-ui/react-dialog';
+
+export function MyDialog() {
+  return (
+    <Dialog.Root>
+      {/* Trigger the dialog */}
+      <Dialog.Trigger asChild>
+        <button className="trigger-styles">Open</button>
+      </Dialog.Trigger>
+
+      {/* Portal renders outside DOM hierarchy */}
+      <Dialog.Portal>
+        {/* Overlay (backdrop) */}
+        <Dialog.Overlay className="overlay-styles" />
+        
+        {/* Content (modal) */}
+        <Dialog.Content className="content-styles">
+          <Dialog.Title>Title</Dialog.Title>
+          <Dialog.Description>Description</Dialog.Description>
+          
+          {/* Your content here */}
+          
+          <Dialog.Close asChild>
+            <button>Close</button>
+          </Dialog.Close>
+        </Dialog.Content>
+      </Dialog.Portal>
+    </Dialog.Root>
+  );
+}
+```
+
+---
+
+## Theming Strategies
+
+### Strategy 1: CSS Variables (Framework-Agnostic)
+
+**Best for**: Maximum portability, SSR-friendly
+
+```css
+/* globals.css */
+:root {
+  --color-primary: 220 90% 56%;
+  --color-surface: 0 0% 100%;
+  --radius-base: 0.5rem;
+  --shadow-lg: 0 10px 15px -3px rgb(0 0 0 / 0.1);
+}
+
+[data-theme="dark"] {
+  --color-primary: 220 90% 66%;
+  --color-surface: 222 47% 11%;
+}
+```
+
+```tsx
+// Component.tsx
+<Dialog.Content 
+  className="
+    bg-[hsl(var(--color-surface))]
+    rounded-[var(--radius-base)]
+    shadow-[var(--shadow-lg)]
+  "
+/>
+```
+
+### Strategy 2: Tailwind + CVA (Class Variance Authority)
+
+**Best for**: Tailwind projects, variant-heavy components
+
+```tsx
+// button.tsx
+import { cva, type VariantProps } from 'class-variance-authority';
+import { cn } from '@/lib/utils';
+
+const buttonVariants = cva(
+  // Base styles
+  "inline-flex items-center justify-center rounded-md font-medium transition-colors focus-visible:outline-none disabled:pointer-events-none disabled:opacity-50",
+  {
+    variants: {
+      variant: {
+        default: "bg-primary text-primary-foreground hover:bg-primary/90",
+        destructive: "bg-destructive text-destructive-foreground hover:bg-destructive/90",
+        outline: "border border-input bg-background hover:bg-accent",
+        ghost: "hover:bg-accent hover:text-accent-foreground",
+      },
+      size: {
+        default: "h-10 px-4 py-2",
+        sm: "h-9 rounded-md px-3",
+        lg: "h-11 rounded-md px-8",
+        icon: "h-10 w-10",
+      },
+    },
+    defaultVariants: {
+      variant: "default",
+      size: "default",
+    },
+  }
+);
+
+interface ButtonProps extends VariantProps<typeof buttonVariants> {
+  children: React.ReactNode;
+}
+
+export function Button({ variant, size, children }: ButtonProps) {
+  return (
+    <button className={cn(buttonVariants({ variant, size }))}>
+      {children}
+    </button>
+  );
+}
+```
+
+### Strategy 3: Stitches (CSS-in-JS)
+
+**Best for**: Runtime theming, scoped styles
+
+```tsx
+import { styled } from '@stitches/react';
+import * as Dialog from '@radix-ui/react-dialog';
+
+const StyledContent = styled(Dialog.Content, {
+  backgroundColor: '$surface',
+  borderRadius: '$md',
+  padding: '$6',
+  
+  variants: {
+    size: {
+      small: { width: '300px' },
+      medium: { width: '500px' },
+      large: { width: '700px' },
+    },
+  },
+  
+  defaultVariants: {
+    size: 'medium',
+  },
+});
+```
+
+---
+
+## Component Patterns
+
+### Pattern 1: Compound Components with Context
+
+**Use case**: Share state between primitive parts
+
+```tsx
+// Select.tsx
+import * as Select from '@radix-ui/react-select';
+import { CheckIcon, ChevronDownIcon } from '@radix-ui/react-icons';
+
+export function CustomSelect({ items, placeholder, onValueChange }) {
+  return (
+    <Select.Root onValueChange={onValueChange}>
+      <Select.Trigger className="select-trigger">
+        <Select.Value placeholder={placeholder} />
+        <Select.Icon>
+          <ChevronDownIcon />
+        </Select.Icon>
+      </Select.Trigger>
+
+      <Select.Portal>
+        <Select.Content className="select-content">
+          <Select.Viewport>
+            {items.map((item) => (
+              <Select.Item 
+                key={item.value} 
+                value={item.value}
+                className="select-item"
+              >
+                <Select.ItemText>{item.label}</Select.ItemText>
+                <Select.ItemIndicator>
+                  <CheckIcon />
+                </Select.ItemIndicator>
+              </Select.Item>
+            ))}
+          </Select.Viewport>
+        </Select.Content>
+      </Select.Portal>
+    </Select.Root>
+  );
+}
+```
+
+### Pattern 2: Polymorphic Components with `asChild`
+
+**Use case**: Render as different elements without losing behavior
+
+```tsx
+// ✅ Render as Next.js Link but keep Radix behavior
+<Dialog.Trigger asChild>
+  <Link href="/settings">Open Settings</Link>
+</Dialog.Trigger>
+
+// ✅ Render as custom component
+<DropdownMenu.Item asChild>
+  <YourCustomButton icon={<Icon />}>Action</YourCustomButton>
+</DropdownMenu.Item>
+```
+
+**Why `asChild` matters**: Prevents nested button/link issues in accessibility tree.
+
+### Pattern 3: Controlled vs Uncontrolled
+
+```tsx
+// Uncontrolled (Radix manages state)
+<Tabs.Root defaultValue="tab1">
+  <Tabs.Trigger value="tab1">Tab 1</Tabs.Trigger>
+</Tabs.Root>
+
+// Controlled (You manage state)
+const [activeTab, setActiveTab] = useState('tab1');
+
+<Tabs.Root value={activeTab} onValueChange={setActiveTab}>
+  <Tabs.Trigger value="tab1">Tab 1</Tabs.Trigger>
+</Tabs.Root>
+```
+
+**Rule**: Use controlled when you need to sync with external state (URL, Redux, etc.).
+
+### Pattern 4: Animation with Framer Motion
+
+```tsx
+import * as Dialog from '@radix-ui/react-dialog';
+import { motion, AnimatePresence } from 'framer-motion';
+
+export function AnimatedDialog({ open, onOpenChange }) {
+  return (
+    <Dialog.Root open={open} onOpenChange={onOpenChange}>
+      <Dialog.Portal forceMount>
+        <AnimatePresence>
+          {open && (
+            <>
+              <Dialog.Overlay asChild>
+                <motion.div
+                  initial={{ opacity: 0 }}
+                  animate={{ opacity: 1 }}
+                  exit={{ opacity: 0 }}
+                  className="dialog-overlay"
+                />
+              </Dialog.Overlay>
+              
+              <Dialog.Content asChild>
+                <motion.div
+                  initial={{ opacity: 0, scale: 0.95 }}
+                  animate={{ opacity: 1, scale: 1 }}
+                  exit={{ opacity: 0, scale: 0.95 }}
+                  className="dialog-content"
+                >
+                  {/* Content */}
+                </motion.div>
+              </Dialog.Content>
+            </>
+          )}
+        </AnimatePresence>
+      </Dialog.Portal>
+    </Dialog.Root>
+  );
+}
+```
+

+### Popover
+
+```tsx
+<Popover.Root>
+  <Popover.Trigger />
+  <Popover.Portal>
+    <Popover.Content side="bottom" align="start">
+      Content

+
+## Accessibility Checklist
+
+### Every Component Must Have:
+
+- [ ] **Focus Management**: Visible focus indicators on all interactive elements
+- [ ] **Keyboard Navigation**: Full keyboard support (Tab, Arrows, Enter, Esc)
+- [ ] **ARIA Labels**: Meaningful labels for screen readers
+- [ ] **Color Contrast**: WCAG AA minimum (4.5:1 for text, 3:1 for UI)
+- [ ] **Error States**: Clear error messages with `aria-invalid` and `aria-describedby`
+- [ ] **Loading States**: Proper `aria-busy` during async operations
+
+### Dialog-Specific:
+- [ ] `Dialog.Title` is present (required for screen readers)
+- [ ] `Dialog.Description` provides context
+- [ ] Focus trapped inside modal when open
+- [ ] Escape key closes dialog
+- [ ] Focus returns to trigger on close
+
+### Dropdown-Specific:
+- [ ] Arrow keys navigate items
+- [ ] Type-ahead search works
+- [ ] First/last item wrapping behavior
+- [ ] Selected state indicated visually and with ARIA
+
+---
+
+## Best Practices
+
+### ✅ Do This
+
+1. **Always use `asChild` to avoid wrapper divs**
+   ```tsx
+   <Dialog.Trigger asChild>
+     <button>Open</button>
+   </Dialog.Trigger>
+   ```
+
+2. **Provide semantic HTML**
+   ```tsx
+   <Dialog.Content asChild>
+     <article role="dialog" aria-labelledby="title">
+       {/* content */}
+     </article>
+   </Dialog.Content>
+   ```
+
+3. **Use CSS variables for theming**
+   ```css
+   .dialog-content {
+     background: hsl(var(--surface));
+     color: hsl(var(--on-surface));
+   }
+   ```
+
+4. **Compose primitives for complex components**
+   ```tsx
+   function CommandPalette() {
+     return (
+       <Dialog.Root>
+         <Dialog.Content>
+           <Combobox /> {/* Radix Combobox inside Dialog */}
+         </Dialog.Content>
+       </Dialog.Root>
+     );
+   }
+   ```
+
+### ❌ Don't Do This
+
+1. **Don't skip accessibility parts**
+   ```tsx
+   // ❌ Missing Title and Description
+   <Dialog.Content>
+     <div>Content</div>
+   </Dialog.Content>
+   ```
+
+2. **Don't fight the primitives**
+   ```tsx
+   // ❌ Overriding internal behavior
+   <Dialog.Content onClick={(e) => e.stopPropagation()}>
+   ```
+
+3. **Don't mix controlled and uncontrolled**
+   ```tsx
+   // ❌ Inconsistent state management
+   <Tabs.Root defaultValue="tab1" value={activeTab}>
+   ```
+
+4. **Don't ignore keyboard navigation**
+   ```tsx
+   // ❌ Disabling keyboard behavior
+   <DropdownMenu.Item onKeyDown={(e) => e.preventDefault()}>
+   ```
+
+---
+
+## Real-World Examples
+
+### Example 1: Command Palette (Combo Dialog)
+
+```tsx
+import * as Dialog from '@radix-ui/react-dialog';
+import { Command } from 'cmdk';
+
+export function CommandPalette() {
+  const [open, setOpen] = useState(false);
+
+  useEffect(() => {
+    const down = (e: KeyboardEvent) => {
+      if (e.key === 'k' && (e.metaKey || e.ctrlKey)) {
+        e.preventDefault();
+        setOpen((open) => !open);
+      }
+    };
+    document.addEventListener('keydown', down);
+    return () => document.removeEventListener('keydown', down);
+  }, []);
+
+  return (
+    <Dialog.Root open={open} onOpenChange={setOpen}>
+      <Dialog.Portal>
+        <Dialog.Overlay className="fixed inset-0 bg-black/50" />
+        <Dialog.Content className="fixed left-1/2 top-1/2 -translate-x-1/2 -translate-y-1/2">
+          <Command>
+            <Command.Input placeholder="Type a command..." />
+            <Command.List>
+              <Command.Empty>No results found.</Command.Empty>
+              <Command.Group heading="Suggestions">
+                <Command.Item>Calendar</Command.Item>
+                <Command.Item>Search Emoji</Command.Item>
+              </Command.Group>
+            </Command.List>
+          </Command>
+        </Dialog.Content>
+      </Dialog.Portal>
+    </Dialog.Root>
+  );
+}
+```
+
+### Example 2: Dropdown Menu with Icons
+
+```tsx
+import * as DropdownMenu from '@radix-ui/react-dropdown-menu';
+import { DotsHorizontalIcon } from '@radix-ui/react-icons';
+
+export function ActionsMenu() {
+  return (
+    <DropdownMenu.Root>
+      <DropdownMenu.Trigger asChild>
+        <button className="icon-button" aria-label="Actions">
+          <DotsHorizontalIcon />
+        </button>
+      </DropdownMenu.Trigger>
+
+      <DropdownMenu.Portal>
+        <DropdownMenu.Content className="dropdown-content" align="end">
+          <DropdownMenu.Item className="dropdown-item">
+            Edit
+          </DropdownMenu.Item>
+          <DropdownMenu.Item className="dropdown-item">
+            Duplicate
+          </DropdownMenu.Item>
+          <DropdownMenu.Separator className="dropdown-separator" />
+          <DropdownMenu.Item className="dropdown-item text-red-500">
+            Delete
+          </DropdownMenu.Item>
+        </DropdownMenu.Content>
+      </DropdownMenu.Portal>
+    </DropdownMenu.Root>
+  );
+}
+```
+
+### Example 3: Form with Radix Select + React Hook Form
+
+```tsx
+import * as Select from '@radix-ui/react-select';
+import { useForm, Controller } from 'react-hook-form';
+
+interface FormData {
+  country: string;
+}
+
+export function CountryForm() {
+  const { control, handleSubmit } = useForm<FormData>();
+
+  return (
+    <form onSubmit={handleSubmit((data) => console.log(data))}>
+      <Controller
+        name="country"
+        control={control}
+        render={({ field }) => (
+          <Select.Root onValueChange={field.onChange} value={field.value}>
+            <Select.Trigger className="select-trigger">
+              <Select.Value placeholder="Select a country" />
+              <Select.Icon />
+            </Select.Trigger>
+            
+            <Select.Portal>
+              <Select.Content className="select-content">
+                <Select.Viewport>
+                  <Select.Item value="us">United States</Select.Item>
+                  <Select.Item value="ca">Canada</Select.Item>
+                  <Select.Item value="uk">United Kingdom</Select.Item>
+                </Select.Viewport>
+              </Select.Content>
+            </Select.Portal>
+          </Select.Root>
+        )}
+      />
+      <button type="submit">Submit</button>
+    </form>
+  );
+}
+```
+
+---
+
+## Troubleshooting
+
+### Problem: Dialog doesn't close on Escape key
+
+**Cause**: `onEscapeKeyDown` event prevented or `open` state not synced
+
+**Solution**:
+```tsx
+<Dialog.Root open={open} onOpenChange={setOpen}>
+  {/* Don't prevent default on escape */}
+</Dialog.Root>
+```
+
+### Problem: Dropdown menu positioning is off
+
+**Cause**: Parent container has `overflow: hidden` or transform
+
+**Solution**:
+```tsx
+// Use Portal to render outside overflow container
+<DropdownMenu.Portal>
+  <DropdownMenu.Content />
+</DropdownMenu.Portal>
+```
+
+### Problem: Animations don't work
+
+**Cause**: Portal content unmounts immediately
+
+**Solution**:
+```tsx
+// Use forceMount + AnimatePresence
+<Dialog.Portal forceMount>
+  <AnimatePresence>
+    {open && <Dialog.Content />}
+  </AnimatePresence>
+</Dialog.Portal>
+```
+
+### Problem: TypeScript errors with `asChild`
+
+**Cause**: Type inference issues with polymorphic components
+
+**Solution**:
+```tsx
+// Explicitly type your component
+<Dialog.Trigger asChild>
+  <button type="button">Open</button>
+</Dialog.Trigger>
+```
+
+---
+
+## Performance Optimization
+
+### 1. Code Splitting
+
+```tsx
+// Lazy load heavy primitives
+const Dialog = lazy(() => import('@radix-ui/react-dialog'));
+const DropdownMenu = lazy(() => import('@radix-ui/react-dropdown-menu'));
+```
+
+### 2. Portal Container Reuse
+
+```tsx
+// Create portal container once
+<Tooltip.Provider>
+  {/* All tooltips share portal container */}
+  <Tooltip.Root>...</Tooltip.Root>
+  <Tooltip.Root>...</Tooltip.Root>
+</Tooltip.Provider>
+```
+
+### 3. Memoization
+
+```tsx
+// Memoize expensive render functions
+const SelectItems = memo(({ items }) => (
+  items.map((item) => <Select.Item key={item.value} value={item.value} />)
+));
+```
+
+---
+
+## Integration with Popular Tools
+
+### shadcn/ui (Built on Radix)
+
+shadcn/ui is a collection of copy-paste components built with Radix + Tailwind.
+
+```bash
+npx shadcn-ui@latest init
+npx shadcn-ui@latest add dialog
+```
+
+**When to use shadcn vs raw Radix**:
+- Use shadcn: Quick prototyping, standard designs
+- Use raw Radix: Full customization, unique designs
+
+### Radix Themes (Official Styled System)
+
+```tsx
+import { Theme, Button, Dialog } from '@radix-ui/themes';
+
+function App() {
+  return (
+    <Theme accentColor="crimson" grayColor="sand">
+      <Button>Click me</Button>
+    </Theme>
+  );
+}
+```

+# Radix UI Design System - Skill Examples
+
+This folder contains practical examples demonstrating how to use Radix UI primitives to build accessible, customizable components.
+
+## Examples
+
+### `dialog-example.tsx`
+
+Demonstrates Dialog (Modal) component patterns:
+- **BasicDialog**: Standard modal with form
+- **ControlledDialog**: Externally controlled modal state
+
+**Key Concepts**:
+- Portal rendering outside DOM hierarchy
+- Overlay (backdrop) handling
+- Accessibility requirements (Title, Description)
+- Custom styling with CSS
+
+### `dropdown-example.tsx`
+
+Complete dropdown menu implementation:
+- **CompleteDropdown**: Full-featured menu with all Radix primitives
+  - Regular items
+  - Separators and labels
+  - Checkbox items
+  - Radio groups
+  - Sub-menus
+- **ActionsMenu**: Simple actions menu for data tables/cards
+
+**Key Concepts**:
+- Compound component architecture
+- Keyboard navigation
+- Item indicators (checkboxes, radio buttons)
+- Nested sub-menus
+
+## Usage
+
+```tsx
+import { BasicDialog } from './examples/dialog-example';
+import { CompleteDropdown } from './examples/dropdown-example';
+
+function App() {
+  return (
+    <>
+      <BasicDialog />
+      <CompleteDropdown />
+    </>
+  );
+}
+```
+
+## Styling
+
+These examples use CSS classes. You can:
+1. Copy the CSS from each file
+2. Replace with Tailwind classes
+3. Use CSS-in-JS (Stitches, Emotion, etc.)
