i18n

i18n is a cursor rule for Cursor from omergulcicek/omergulcicek.com. It costs 0 tokens per session (323 once invoked), scanned A, a copy of i18n, MIT.

A set of rules for managing translation files, language keys, and multilingual application logic.

In plain words
What is it for?
It helps developers add and maintain localized messages and language-aware features.
Why use it?
It prevents inconsistent translation structures, missing type safety, and hardcoded text in user interfaces.

Getting it into your agent

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

i18n 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 4d 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.

Origin

This is a copy

100% identical to i18n — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Internationalization (i18n)

Constraints

  • Library Selection: Delegate specific hook/method usage to the framework constitution (nextjs.mdc or tanstack-start.mdc).
  • Keys: Use flat or max 3-level deep JSON structures. Use camelCase for keys.
  • SSOT: All translation keys MUST be defined in src/messages/.
  • Type Safety: Use the library's native type-generation features. Magic strings for keys are forbidden.
  • Namespacing: Use namespaces for features (e.g., auth.login, profile.settings) to maintain modularity.

Bans

  • Hardcoded strings in UI components.
  • Dynamic key construction (e.g., t("prefix." + variable)).
  • Reading locale via window.location or manual URL parsing.
  • JSON hierarchy deeper than 3 levels.
  • Async translation loading that causes layout shifts.

Correct Implementation

Incorrect Implementation

// BAN: Dynamic key generation const label = t("welcome_" + type);

Changes

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.
