Coding & Development Prompts

Scaffold a production App Router page: Server Component data fetching, Suspense streaming for instant TTFB, correct cache strategy (fetch cache vs unstable_cache vs revalidatePath), loading/error boundaries, and generateMetadata — with the non-obvious patterns most tutorials skip.

Production-grade dashboard layout: KPI cards with counting animations and trend sparklines, a chart area, activity table — all with dark mode, skeleton loading states, and responsive breakpoints defined to the pixel.

Generate correct, non-recursive RLS policies so anyone reads published rows and only owners edit their own.

Production-ready Stripe webhook route that verifies the signature and processes events exactly once.

A tuned .cursorrules file that keeps Cursor's agent on-convention: strict types, no dead code, match existing patterns.

Extract stateful logic from a bloated component into typed, testable custom hooks.

Paste a slow query and get a root-cause diagnosis, targeted index/rewrite fixes, and a before/after query plan — with specific pattern detection for N+1s, implicit casts, and composite index gaps.

Design a production JWT auth flow with access/refresh rotation, token family revocation, and a concrete threat model — including the 6 common JWT mistakes that lead to breaches and how to avoid each one.

Turn a feature description into a normalized Prisma schema with relations, indexes, and migration-safe defaults.
