Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.00347 |
| Opus 5 | $0.00000 | $0.00173 |
| Sonnet 5 | $0.00000 | $0.00069 |
| Haiku 4.5 | $0.00000 | $0.00035 |
Grade A, and why
nextjs-pages scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
App Router pages
Structure
- All user-facing routes:
src/app/[locale]/… - Root metadata routes:
src/app/sitemap.ts,src/app/robots.ts(not locale-scoped) - Catch-all
src/app/[locale]/[...rest]/page.tsx→notFound()
Server page template
import { setRequestLocale, getTranslations } from "next-intl/server";
export default async function Page({
params,
}: {
params: Promise<{ locale: string }>;
}) {
const { locale } = await params;
setRequestLocale(locale);
const t = await getTranslations({ locale, namespace: "YourNamespace" });
return <h1>{t("title")}</h1>;
}
Layout (src/app/[locale]/layout.tsx)
- Validate locale with
hasLocale(routing.locales, locale)→notFound(). - Set
<html lang={locale} dir={locale === "ar" ? "rtl" : "ltr"}>. generateStaticParamsmust list allrouting.locales.
React 19 constraints
- JSON-LD: Server Component only; serialize with
JSON.stringify(data).replace(/</g, "\\u003c"). - No
next/scriptor client-side<script>for theme — cookie SSR in layout.
Params
- Next.js 16:
paramsandsearchParamsare Promises — alwaysawait params.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

nextjs-pages is a cursor rule published in the GitHub repository s0vers/next-app-i18n-starter (64 stars, last pushed 2mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 347 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other cursor rules, from other repositories
components
React component architecture for creating composable, accessible components with data attributes. Use when creating/updating composable components, not for higher-level feature/page components.
react
React patterns with destructured props, compiler optimization, Effects, and Tailwind v4 syntax. ALWAYS use when using React.
frontend-rules
Cursor rule "frontend-rules" from robotostudio/turbo-start-sanity, covering component structure and internationalization rules.
hydration-safety
React hydration mismatch prevention.
middleware-auth
Next.js middleware auth — prevents auth logic being placed in middleware instead of route handlers.
performance
Next.js performance optimization — caching, bundle size, and Core Web Vitals.
