Payload CMS × Claude Prompt Engineering

Stop fighting Claude hallucinations. Generate Payload CMS-aware prompts that produce code your team can actually ship.

❌ Generic AI Output

// ❌ Generic Claude output for Payload CMS
// Missing Payload CMS conventions
// No error handling, no types
// Ignores Next.js 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 Payload CMS conventions enforced
// Proper error handling & types
// Next.js best practices included
// Production-ready, zero hallucinations

Real Generated Output

Automated Quality Enforcement

Every prompt includes strict bans and deprecation rules tailored to your Payload CMS + Next.js + TypeScript + MongoDB + Claude stack

strict-bans.md — AI Prompt Architect

# ⛔ 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 treats Payload like WordPress, ignores collection config patterns, and misuses field-level access control. Claude can hallucinate API signatures and produce overly verbose implementations.

✅ The Solution

AI Prompt Architect Prompts enforce Payload collection configs, hooks (beforeChange/afterRead), and proper field-level access functions. It provides Claude with constraints and examples that reduce hallucination and enforce concise output.

Frequently Asked Questions

Does it work with Claude?

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

Can it handle Payload CMS projects?

Absolutely. Prompts include Payload CMS-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 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 Claude?

It structures prompts with Claude's XML tag format, explicit constraint blocks, and few-shot examples that reduce hallucination. The system leverages Claude's strength with long context by including full schema definitions.
