i18n-translation-system

i18n-translation-system is a cursor rule for Cursor from speraxos/SperaxOS-AI-Agents. It costs 0 tokens per session (956 once invoked), scanned A, a copy of i18n-translation-system, MIT.

A project guide for translating selected text into different languages and checking that each result uses the expected language. I18n means designing software to support multiple languages and regions.

In plain words
What is it for?
Use it to detect changed source text, translate only new or changed fields, merge results, validate languages, and save the formatted output.
Why use it?
It avoids retranslating unchanged content and catches translations that are missing, outdated, or in the wrong language.

Cursor rule for Cursor

Written for Cursor: installed under .cursor/.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import { validateTranslationLanguage } from '../validators/language-validator';.

Good fit Use it to detect changed source text, translate only new or changed fields, merge results, validate languages, and save the formatted output.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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-translation-system 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 11d 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-translation-system — 2 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.

I18n Translation System Guide

This project implements an intelligent translation system with incremental detection and language validation.

🌍 Translation Workflow

Core Components

Translation Process Flow

  1. Source Detection: Extract translatable fields from source files
  2. Incremental Check: Compare with existing translations to detect changes
  3. Translation: Use OpenAI to translate only new/changed content
  4. Merge: Combine new translations with existing ones
  5. Validation: Verify translation language matches expected locale
  6. Format: Apply formatting and save results

🔄 Incremental Translation Logic

Key Method: getIncrementalData()

Located in scripts/formatters/agent-formatter.ts:

private getIncrementalData = (sourceData: any, existingData: any) => {
  const needsTranslation = {};
  let hasUpdates = false;

  for (const key of config.selectors) {
    const sourceValue = get(sourceData, key);
    const existingValue = get(existingData, key);

    if (sourceValue && !isEqual(sourceValue, existingValue)) {
      set(needsTranslation, key, sourceValue);
      hasUpdates = true;
    }
  }

  return { hasUpdates, needsTranslation };
};

Translation Strategy

  • Full Translation: When no existing translation file exists
  • Incremental Translation: When changes detected in source content
  • Skip Translation: When no changes detected (content unchanged)
  • Merge Results: Combine new translations with existing using lodash.merge

🛡️ Language Validation

Validation Process

Uses @yutengjing/eld library for language detection:

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.
