Same prompt. Same project. The only difference is whether PromptPack rules are loaded.
Without PromptPack
// Pages Router pattern in App Router
export async function getServerSideProps({
params
}) {
const product = await
db.product.findUnique({
where: { slug: params.slug }
});
return { props: { product } };
}
export default function ProductPage({ product }) {
const [data, setData] = useState(product);
useEffect(() => {
if (!data) router.push('/404');
}, [data]);
return <ProductView product={data} />;
}Deprecated data fetching. Wrong client/server boundary. useEffect for what should be a Server Component.
With PromptPack
// Proper Next.js 16 App Router
export default async function ProductPage({
params
}: Props) {
const { slug } = await params;
const product = await
db.product.findUnique({
where: { slug }
});
if (!product) notFound();
return <ProductView product={product} />;
}Async params. Direct Server Component fetch. notFound() instead of client-side redirect. Half the code.
Without rules, Cursor and Claude Code default to their training data — and that means getServerSideProps, sync cookies()/headers()/params, unstable_cache, and middleware.ts where proxy.ts belongs. These templates fix that. You drop them in, and the AI starts writing actual Next 16 code.
You add this rule
## Server Components
# Default to async Server
# Components. Fetch data at the
# component level.
#
# NEVER use useEffect for data
# fetching. Only add "use client"
# when you need hooks or browser
# APIs.
## Error Handling
# Create error.tsx for every route.
# Use notFound() for missing items.
# Always add loading.tsx with a
# skeleton that matches the layout.Cursor generates this
async function ProductPage({
params
}: Props) {
const { slug } = await params;
const product = await
db.product.findUnique({
where: { slug }
});
if (!product) notFound();
return (
<ProductView
product={product}
/>
);
}No useEffect. No "use client". Proper notFound() handling. That's what good rules do.
Markdown templates, sharded .cursor/rules MDC, .claude/skills hybrids, sub-agents, hooks, .mcp.json, .claude/settings.json — plus AGENTS.md as the cross-tool primary spec. The full agentic stack, tuned for Next 16.
Every template ships with rules, anti-patterns, a worked example, and Next 16 API references. Plus 9 sharded .cursor/rules MDC files and 5 .claude/skills hybrids on the top-baseline templates.
I'm Daniel, a solo developer from Hungary. I build production Next.js apps and I use Cursor and Claude Code daily.
A few months ago I realized I was spending more time correcting my AI than actually coding. It kept generating Pages Router patterns in my App Router projects. Client components where server components should be. useEffect for data fetching. The works.
So I started writing rules — specific, opinionated instructions that tell the AI exactly how my project works. The difference was night and day. I went from "fix this, no not like that" to code I could actually use on the first try.
v1.0 shipped in April with 52 templates for Next 15. Then Next 16 dropped, Cursor deprecated .cursorrules in favor of sharded MDC, and AGENTS.md became the cross-tool standard. v2.0 is the rebuild: 60+ templates, skills, and configs, tuned for Next 16 from end to end.

What format are the templates?
Markdown templates plus a sharded .cursor/rules directory of MDC files, .claude/skills hybrids, sub-agent definitions, hook scripts, .mcp.json, and .claude/settings.json. Drop them into your project root — no config, no build step, nothing to install.
Do I get updates?
Yes. Free updates through 2027-05 (12 months from v2.0 ship). v2.5 within 90 days adds a Next 16 SaaS-app starter template to the bundle. v3.0 within 6 months adds Stripe Checkout + Webhook, Better Auth, React 19 advanced patterns, and a Skills system deep-dive — all bundled as new templates in the pack. No separate SaaS service, no add-on subscription.
What if they don't work for my project?
