Cursor 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.

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.

A conversion-optimized build spec that nails the persuasion sequence, scroll-triggered animations, mobile-first breakpoints, and Core Web Vitals — not just 'build me a landing page.'

A staged build spec for a 3-role food-delivery MVP (customer / restaurant / driver) on Next.js + Supabase + Stripe.

A ride-share MVP spec with Supabase realtime location streaming, a surge-aware fare calculator, driver matching logic, and a clear Phase 2 roadmap — not just 'build an Uber clone.'

A short-video social MVP: vertical snap-scroll feed, uploads, likes/comments/follows, and a basic For-You ranking.

Goes beyond 'build a SaaS' — specifies the patterns that actually make or break an MVP: tenant-isolated data, Stripe webhook flows, invite-based teams, usage metering, and an onboarding funnel.

Starts with a structured game design document (core loop, Bartle motivation type, the one mechanic that makes it unique), then prototypes the core loop first with playtest checkpoints — not just 'make me a game.'

Goes beyond 'make a platformer' — specifies the exact physics values that make jumps feel great (coyote time, input buffering, variable gravity), the juice layer (screen shake, squash-stretch, particles), and the level design methodology that teaches mechanics through play.

Describe your endpoint in plain English and Codex builds the full implementation: route handler, request validation, error responses, and a usage example — no boilerplate writing required.

Paste any function and Codex returns a plain-English explanation, a list of specific problems, and a refactored version with notes on every change — so you understand what changed and why.

Point Codex at any function and it writes the full test suite: happy path, edge cases, error conditions, and the mocks — covering what you'd write manually but in a fraction of the time.

Paste the buggy code and the error, and Codex diagnoses the root cause, explains why the obvious fix won't work, and gives you the correct fix with a regression test so the bug can never come back silently.

Turns a vague component idea into a typed, accessible Expo + React Native component with a documented prop API, themeable styles, full state handling, and a usage example.

Produces a maintainable Unity C# controller using proper component separation, the chosen input system, and inspector-tunable values — not a messy god-class in Update().

Gives you a reproducible, well-structured PyTorch training script — config, model, dataloaders, train/eval loop, metrics, checkpointing, and early stopping — tuned to your task.

Produces a typed, reusable React Native form with controlled inputs, inline validation, accessible error messaging, and submit/disabled states instead of wiring each field by hand.

Produces a typed useOfflineQuery hook with cache-first reads, optimistic revalidation, and retry-on-reconnect, plus a FlatList that renders loading, empty, error, stale, and offline states honestly.
