Turborepo + Next.js × Devin AI Prompt Engineering

Stop fighting Devin hallucinations. Generate Turborepo + Next.js-aware prompts that produce code your team can actually ship.

❌ Generic AI Output

// ❌ Generic Devin output for Turborepo + Next.js
// Missing Turborepo conventions
// No error handling, no types
// Ignores Next.js best practices
function getData() {
  // hallucinated API
  return fetch('/api/data').then(r => r.json());
}

✅ Prompt Architect Output

// ✅ AI Prompt Architect output
// Full Turborepo conventions enforced
// Proper error handling & types
// Next.js best practices included
// Production-ready, zero hallucinations

# ⛔ 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

Devin ignores monorepo boundaries, produces circular deps, and misconfigures Turborepo caching. Devin's autonomous coding sessions can drift from project conventions without structured prompts.

✅ The Solution

AI Prompt Architect enforces package boundaries, shared configs, turbo.json pipeline optimization, and workspace deps. It structures prompts that keep Devin aligned with your codebase conventions across autonomous sessions.

Frequently Asked Questions

Does it work with Devin AI?

Yes. AI Prompt Architect generates prompts optimised for Devin, including workspace context and constraint syntax that keeps Devin's autonomous sessions on-track.

Can it handle Turborepo projects?

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

Is there a free tier?

Yes — sign up for free and receive 1 analysis credit to try the platform. Paid tiers unlock more credits, generations, and advanced features.

Technical Deep Dive

How does it handle the Next.js App Router vs Pages Router distinction?

Prompts detect your router configuration and enforce the correct patterns — layout.tsx/page.tsx for App Router or getServerSideProps/getStaticProps for Pages Router. Mixed configurations are flagged during prompt generation.

Can it generate prompts for Next.js middleware and Edge Functions?

Yes — the constraint engine includes Edge Runtime limitations (no Node.js APIs, limited crypto), proper NextRequest/NextResponse patterns, and correct matcher configurations for middleware chains.

How does AI Prompt Architect optimise prompts for Devin?

It structures prompts for autonomous multi-step execution — encoding verification checkpoints, rollback boundaries, and explicit success criteria. The system ensures Devin stays aligned with your conventions across long autonomous sessions.
