Angular 18 × Cursor AI Prompt Engineering

Stop fighting Cursor AI hallucinations. Generate Angular 18-aware prompts that produce code your team can actually ship.

❌ Generic AI Output

// ❌ Generic Cursor AI output for Angular 18
// Missing Angular 18 conventions
// No error handling, no types
// Ignores Signals best practices
function getData() {
  // hallucinated API that doesn't exist
  return fetch('/api/data').then(r => r.json());
}

✅ Prompt Architect Output

// ✅ AI Prompt Architect output
// Full Angular 18 conventions enforced
// Proper error handling & types
// Signals best practices included
// Production-ready, zero hallucinations

Real Generated Output

Automated Quality Enforcement

Every prompt includes strict bans and deprecation rules tailored to your Angular 18 + Signals + RxJS + TypeScript + Cursor AI stack

# ⛔ STRICT BANS — Enforced Constraints

## Framework Version Enforcement
- **BANNED**: React class components → Use functional components + hooks
- **BANNED**: `componentWillMount`, `componentWillUpdate` → Use `useEffect`
- **BANNED**: `getInitialState` → Use `useState` or `useReducer`
- **BANNED**: `createClass` syntax → Use arrow function components
- **BANNED**: PropTypes runtime validation → Use TypeScript interfaces
- **BANNED**: `defaultProps` static → Use ES6 default parameters

## TypeScript Enforcement
- **BANNED**: `any` type annotations → Use `unknown` + type guards
- **BANNED**: `@ts-ignore` comments → Fix the actual type error
- **BANNED**: Non-null assertions (`!`) → Use optional chaining (?.)
- **BANNED**: `enum` keyword → Use `as const` union types
- **BANNED**: `namespace` declarations → Use ES modules

## Security Constraints
- **BANNED**: `eval()`, `Function()` constructors
- **BANNED**: `innerHTML` assignments → Use `textContent` or sanitise
- **BANNED**: Hardcoded secrets, API keys, or credentials
- **BANNED**: `http://` URLs in production → Enforce `https://`
- **BANNED**: `*` CORS origins in production → Whitelist domains
- **BANNED**: SQL string concatenation → Use parameterised queries
- **BANNED**: `localStorage` for auth tokens → Use httpOnly cookies

## State Management
- **BANNED**: Prop drilling beyond 2 levels → Use Context or Zustand
- **BANNED**: `useEffect` for data fetching → Use React Query / SWR
- **BANNED**: Mutable state mutations → Use immutable update patterns
- **BANNED**: Global mutable variables → Use React state or stores

## API & Data Patterns
- **BANNED**: `fetch` without error handling → Wrap in try/catch
- **BANNED**: Untyped API responses → Define response interfaces
- **BANNED**: `console.log` in production → Use structured logger
- **BANNED**: Synchronous file I/O → Use async/await patterns
- **BANNED**: Unbounded `.find()` / `.filter()` on large arrays → Use Map/Set

## CSS & Styling
- **BANNED**: Inline styles for layout → Use CSS modules or Tailwind
- **BANNED**: `!important` overrides → Fix specificity properly
- **BANNED**: Fixed pixel breakpoints → Use relative units (rem/em)
- **BANNED**: `z-index` values > 100 → Use a z-index scale system

❌ The Problem

AI outputs deprecated NgModules, ignores standalone components, and misuses Angular signals vs observables. Cursor's tab-completion often suggests code that ignores project-wide conventions.

✅ The Solution

AI Prompt Architect Prompts enforce standalone components, signal-based reactivity, and proper inject() patterns from Angular 18+. It constrains Cursor to your exact project patterns via .cursorrules and structured prompt context.

Frequently Asked Questions

Does it work with Cursor AI?

Yes. AI Prompt Architect generates prompts optimised for Cursor AI, including context formatting and constraint syntax that Cursor AI responds best to.

Can it handle Angular 18 projects?

Absolutely. Prompts include Angular 18-specific conventions, API patterns, and best practices to eliminate common hallucinations.

Is there a free tier?

Yes — generate up to 5 prompts per day for free. Pro tier unlocks unlimited generations, team sharing, and advanced templates.

Technical Deep Dive

How does it handle Angular standalone components and signal-based reactivity?

Prompts enforce standalone: true, signal() / computed() / effect() patterns from Angular 16+, and proper inject() usage instead of constructor injection. NgModules are excluded from generated code.

Can it generate prompts for Angular SSR with hydration?

Yes — the system encodes provideClientHydration(), proper TransferState usage, and withHttpTransferCacheInterceptor patterns. Non-destructive hydration boundaries are correctly annotated.

How does AI Prompt Architect optimise prompts specifically for Cursor AI?

It generates .cursorrules files and structured prompt context that Cursor reads automatically. This includes project-specific conventions, import patterns, and file organisation rules that persist across sessions.
