creo-i18n

creo-i18n is a skill for Claude Code from oyusypenko/creo. It costs 62 tokens per session (1,150 once invoked), scanned A, original, MIT.

A translation tool for JSON language files, using a locally running language model through LM Studio. It keeps the file structure and placeholders while translating into 39 or more listed languages.

In plain words
What is it for?
Batch-translating locale files, validating translated JSON against the source, and checking which language translations are complete or have problems.
Why use it?
It removes the need to translate each locale file by hand and checks that translated files still match the source structure. It requires LM Studio, a loaded model, and source files in the expected location.

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

creo-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 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.

i18n Translator Skill

Batch translate JSON locale files using a local LLM via LM Studio. Preserves JSON structure, placeholders, and validates output.

Commands

Command Description
/creo i18n translate <source-lang> <target-langs> Translate JSON files from source language to one or more target languages (comma-separated)
/creo i18n validate Validate that translated files match source structure
/creo i18n status Show translation status: which languages are done, which have issues

Examples

/creo i18n translate en uk,pl,de
/creo i18n translate en fr
/creo i18n validate
/creo i18n status

Prerequisites

  • Python 3.8+ with requests package
  • LM Studio running locally on port 1234 (default) with a loaded model
  • Source JSON locale files in the input/ directory

Supported Languages (39+)

Code Language Code Language Code Language
ar Arabic bg Bulgarian cs Czech
da Danish de German el Greek
en English es Spanish et Estonian
fi Finnish fr French he Hebrew
hi Hindi hr Croatian hu Hungarian

pl Polish pt Portuguese ro Romanian
ru Russian sk Slovak sl Slovenian
sr Serbian sv Swedish th Thai
tr Turkish ua Ukrainian vi Vietnamese
zh Chinese (Simplified) zh-TW Chinese (Traditional) fil Filipino

You can specify any language code supported by your LLM model.

How It Works

  1. Source files: Place JSON locale files in the input/ directory
  2. Configure: Edit config.json to set source language, target languages, and LM Studio URL
  3. Translate: The translator walks each JSON file recursively, sending each string value to the LLM with context (the JSON key path)
  4. Validate: After translation, the validator checks that every translated file has the exact same structure as the source
  5. Output: Translated files are saved to output/<lang>/ preserving the original directory structure

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.
