How to Get Best Results with Claude 3.5 Sonnet & DeepSeek V4 Flash

1. Select the Right Coding Model

Use Claude 3.5 Sonnet for complex Next.js App Router architecture and Tailwind UI, or DeepSeek V4 Flash for ultra-fast SQL queries and utility functions.

2. Provide Exact Stack Constraints

Specify Next.js 15 App Router, Server Actions, Prisma/PostgreSQL, and strict TypeScript types so the output compiles on the first try.

3. Request Edge-Case & Idempotency Guards

Always ask the model to handle race conditions, webhook retries, and Zod input validation.

Idempotent Payment Webhook Handler

“Write a production-ready Next.js 15 App Router API route (/api/webhooks/paypal/route.ts) in strict TypeScript that verifies webhook signatures, uses a PostgreSQL transaction lock to guarantee idempotency against duplicate webhook deliveries, credits user MANA balances, and logs audit events.”

Producer Tip: Claude 3.5 Sonnet excels at writing race-condition-proof transactional billing logic.
