Cursor IDE AI Prompt Engineering: 10 Expert Rules for Production-Ready Code Generation with ChatGPT, Claude, and Copilot

// ❌ BAD PROMPT (Generates Generic Code):
"Create a user authentication function"
// ✅ OPTIMIZED PROMPT FOR AI (Generates Production Code):
"Using Next.js 14 App Router, TypeScript 5.0, Prisma ORM with PostgreSQL,
and NextAuth.js v5, create a server-side authentication middleware
that validates JWT tokens and implements role-based access control
for protecting /admin/* routes with proper error handling"

// ✅ PERFECT PROMPT FOR REACT HOOK GENERATION:
"Create a custom React 18 hook with TypeScript that debounces API calls
Input: searchTerm = 'react' (user types: 'r', 're', 'rea', 'reac', 'react')
Output: Only ONE API call after 500ms of no typing
Return: { data: User[], loading: boolean, error: Error | null }
Dependencies: TanStack Query v5, axios, TypeScript strict mode
Requirements: Handle race conditions, cleanup on unmount"

// ❌ WRONG (Too Complex for AI):
"Build complete e-commerce checkout with Stripe"
// ✅ RIGHT (Atomic Prompts for Each Part):
// Prompt 1: "Create Node.js Stripe payment intent generator with TypeScript"
// Prompt 2: "Build React 18 credit card form with react-hook-form validation"
// Prompt 3: "Implement Express.js webhook handler for Stripe events"
// Prompt 4: "Add idempotency keys for duplicate payment prevention"

// ✅ TYPESCRIPT + SECURITY CONSTRAINT TEMPLATE:
"Create Express.js REST API endpoint for user profile data
MUST HAVE:
✓ Input validation with Zod schema
✓ Rate limiting with express-rate-limit (100 req/min)
✓ Winston logging with correlation IDs
✓ Proper TypeScript types (no implicit any)
✓ JWT verification with jose library
MUST NOT:
✗ Use 'any' TypeScript type
✗ Return raw database errors to client
✗ Use synchronous file operations
✗ Store sensitive data in JWT payload
✗ Use deprecated Express methods"

// ✅ NEXT.JS 14 PROJECT CONTEXT:
"Project structure for Next.js 14 App Router:
- /app/api/[...route]/route.ts - API routes
- /lib/db/* - Prisma database queries  
- /lib/services/* - Business logic layer
- /components/ui/* - shadcn/ui components
- /hooks/use*.ts - Custom React hooks
- /types/*.d.ts - TypeScript type definitions
- Error handling: Custom AppError class extends Error
- Authentication: NextAuth with JWT strategy
Create user notification feature following these patterns"

// ✅ ADD TO ALL COMPLEX PROMPTS:
"After generating the code, explain:
1. Algorithm choice and alternatives considered
2. Time complexity (Big O notation)
3. Space complexity analysis  
4. Potential race conditions or deadlocks
5. Security implications and attack vectors
6. Browser compatibility (if frontend)
7. Performance optimization opportunities"

// PROGRESSIVE ENHANCEMENT WITH AI:
// Iteration 1: "Create React table component with TypeScript interfaces"
// Iteration 2: "Add sorting to existing table, preserve all types"
// Iteration 3: "Add pagination with URL state management (using URLSearchParams)"
// Iteration 4: "Add react-window virtualization for 10k+ rows performance"
// Iteration 5: "Add CSV export functionality with Web Workers"

// ✅ DEBUGGING PROMPT TEMPLATE:
"Next.js 14 production build error:
ERROR MESSAGE:
Error: Hydration failed because initial UI does not match server
at throwOnHydrationMismatch (react-dom.development.js:12507:9)
at tryToClaimNextHydratableInstance (react-dom.development.js:12535:5)
CONTEXT:

Only occurs with date formatting using date-fns
Component: TimeAgo.tsx using formatDistanceToNow()
Environment: Next.js 14.0.3, React 18.2.0, Node 20.x
Deployment: Vercel Edge Functions
Browser: Chrome 120, Safari 17

CURRENT CODE:
[paste TimeAgo component code]
How do I fix this hydration mismatch?"

// ✅ QUALITY METRICS TEMPLATE:
"Build React autocomplete search component:
PERFORMANCE:

First Contentful Paint: <1.5s
Response time: <100ms per keystroke
Debounce: 300ms
Bundle size: <10KB gzipped
Memory: No leaks, cleanup on unmount

TESTING:

Jest + React Testing Library
Minimum 80% code coverage
E2E tests with Playwright
Accessibility: WCAG 2.1 AA compliant

MONITORING:

Sentry error tracking
DataDog performance monitoring"

// ✅ VALIDATION PROMPT PREFIX:
"Before writing any code, please confirm:

PROBLEM: What specific problem are we solving?
USERS: Who will use this code? (developers/end-users)
CONSTRAINTS: What are the technical limitations?
EDGE CASES: What unusual inputs should we handle?
PERFORMANCE: What are the scalability requirements?
TESTING: How will this be tested?
DEPLOYMENT: Where will this run? (browser/server/edge)

After confirming understanding, provide the implementation."
