AGENTS.md

next-app-i18n-starter AGENTS.md is an instructions file for Codex, OpenCode from s0vers/next-app-i18n-starter. It costs 630 tokens per session, scanned A, original, MIT.

Repository instructions for AI coding assistants working on a Next.js starter project with translations, right-to-left language support, themes, and search-engine settings.

In plain words
What is it for?
Use them when changing this project so code follows its structure, translation files stay consistent, secrets remain protected, and builds and checks are run after substantial changes.
Why use it?
They give the assistant project-specific rules, such as which package manager and navigation methods to use, and which files must be updated together.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Cursor.

This is s0vers/next-app-i18n-starter's own configuration. It tells Codex and OpenCode how to work on next-app-i18n-starter itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything next-app-i18n-starter configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

next-app-i18n-starter AGENTS.md 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 9d 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.

Agent guide

Instructions for AI coding assistants working in this repository.

Project

Next.js 16 App Router boilerplate with next-intl 4, locale-driven formatting, shadcn/ui, RTL, cookie-based theme SSR, and full SEO.

  • Package manager: bun (preferred) or pnpm — not npm/yarn
  • Node: 24.x (see .nvmrc, package.json engines)
  • After substantive changes: bun run build (and bun run lint when touching TS/TSX)

Non-negotiables

  1. Never edit .env or commit secrets — use .env.example as the template only
  2. Navigation: use @/i18n/navigation (Link, useRouter, usePathname, getPathname) — not next/link or next/navigation directly
  3. Translations: en.json is the type source of truth; add keys to all dictionary/*.json files
  4. Locale pages: call setRequestLocale(locale) in Server Components under src/app/[locale]/
  5. URLs for SEO: build with getPathname — English is / (localePrefix: "as-needed"), not /en
  6. React 19: no next/script or inline <script> in client components; JSON-LD in Server Components only
  7. Minimize diff scope — match existing patterns; no drive-by refactors

Cursor rules

Detailed, file-scoped rules live in .cursor/rules/. Cursor loads them automatically.

File Purpose
project-core.mdc Tooling, env, commits, general standards
i18n.mdc Locales, dictionaries, regional formatting
nextjs-pages.mdc App Router pages and layouts
seo.mdc Metadata, sitemap, robots, canonical URLs
components.mdc React components, shadcn, RTL, theme

Deep reference

Common tasks (pointers)

Task Where to look
Add language src/i18n/locales.ts (localeConfig) — routing, regional, OG, and switcher derive from it
Add page src/app/[locale]/…/page.tsx, dictionary namespace, @/i18n/navigation links
Add SEO to page generateMetadata, dictionary meta keys, sitemap.ts entry
RTL islands OmitRTL from @/components/OmmitRlt
Site constants src/lib/site.ts

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.
