### Multi-Skill Workflows

Complex tasks combine multiple skills:

Feature Development: Feature Forge → Architecture Designer → Fullstack Guardian → Test Master → DevOps Engineer Bug Investigation: Debugging Wizard → Framework Expert → Test Master → Code Reviewer Security Hardening: Secure Code Guardian → Security Reviewer → Test Master

Core Workflow

1. Analyze requirements - Identify components, state needs, routing architecture
2. Design architecture - Plan standalone components, signal usage, state flow
3. Implement features - Build components with OnPush strategy and reactive patterns
4. Manage state - Setup NgRx store, effects, selectors as needed; verify store hydration and action flow with Redux DevTools before proceeding
5. Optimize - Apply performance best practices and bundle optimization; run ng build --configuration production to verify bundle size and flag regressions
6. Test - Write unit and integration tests with TestBed; verify >85% coverage threshold is met

Standalone Component with OnPush and Signals

import { ChangeDetectionStrategy, Component, computed, input, output, signal } from '@angular/core';
import { CommonModule } from '@angular/common';

@Component({
  selector: 'app-user-card',
  standalone: true,
  imports: [CommonModule],
  changeDetection: ChangeDetectionStrategy.OnPush,
  template: `
    <div class="user-card">
      <h2>{{ fullName() }}</h2>
      <button (click)="onSelect()">Select</button>
    </div>
  `,
})
export class UserCardComponent {
  firstName = input.required<string>();
  lastName = input.required<string>();
  selected = output<string>();

  fullName = computed(() => `${this.firstName()} ${this.lastName()}`);

  onSelect(): void {
    this.selected.emit(this.fullName());

RxJS Subscription Management with takeUntilDestroyed

import { Component, OnInit, inject } from '@angular/core';
import { takeUntilDestroyed } from '@angular/core/rxjs-interop';
import { UserService } from './user.service';

@Component({ selector: 'app-users', standalone: true, template: `...` })
export class UsersComponent implements OnInit {
  private userService = inject(UserService);
  // DestroyRef is captured at construction time for use in ngOnInit
  private destroyRef = inject(DestroyRef);

  ngOnInit(): void {
    this.userService.getUsers()
      .pipe(takeUntilDestroyed(this.destroyRef))
      .subscribe({
        next: (users) => { /* handle */ },
        error: (err) => console.error('Failed to load users', err),
      });
  }
}

NgRx Action / Reducer / Selector

// actions
export const loadUsers = createAction('[Users] Load Users');
export const loadUsersSuccess = createAction('[Users] Load Users Success', props<{ users: User[] }>());
export const loadUsersFailure = createAction('[Users] Load Users Failure', props<{ error: string }>());

// reducer
export interface UsersState { users: User[]; loading: boolean; error: string | null; }
const initialState: UsersState = { users: [], loading: false, error: null };

export const usersReducer = createReducer(
  initialState,
  on(loadUsers, (state) => ({ ...state, loading: true, error: null })),
  on(loadUsersSuccess, (state, { users }) => ({ ...state, users, loading: false })),
  on(loadUsersFailure, (state, { error }) => ({ ...state, error, loading: false })),
);

// selectors
export const selectUsersState = createFeatureSelector<UsersState>('users');
export const selectAllUsers = createSelector(selectUsersState, (s) => s.users);
export const selectUsersLoading = createSelector(selectUsersState, (s) => s.loading);
