N.E.K.O: Skill for Claude Code

.agent/skills/i18n/SKILL.md

i18n is a skill for Claude Code, Codex from Project-N-E-K-O/N.E.K.O. It costs 114 tokens per session (701 once invoked), scanned A, original, Apache-2.0.

A translation-management toolkit for projects using i18next, a JavaScript library for showing text in different languages.

In plain words
What is it for?
Use it to check and replace hardcoded text in HTML and JavaScript, add translation keys, and sync locale files for languages such as English, Chinese, Japanese, Korean, Russian, Spanish, and Portuguese.
Why use it?
It finds hardcoded Chinese text and keeps translation keys aligned across language files, reducing missing or inconsistent translations.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

This is Project-N-E-K-O/N.E.K.O's own configuration. It tells Claude Code and Codex how to work on N.E.K.O 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 N.E.K.O configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is uv run python scripts/i18n_sync.py # Check status.

About the project

N.E.K.O is a real-time AI catgirl companion designed to live with the user, initiate interaction, share media, and perform tasks through an emotional engine. It is intended for people seeking a proactive personal digital companion. The catalogue contains skills for working with it.

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 10d 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

i18n Toolkit

Complete i18n (internationalization) toolkit for projects using i18next.

Architecture

  • i18n library: i18next
  • Locale files: static/locales/ (zh-CN, zh-TW, en, ja, ko, ru, es, pt)
  • HTML attributes: data-i18n, data-i18n-placeholder, data-i18n-title, data-i18n-alt
  • JS function: window.t() or i18next.t()
  • Progress file: .claude/i18n-progress.json

Three Main Commands

1. i18n-check - Detect Issues

Check frontend files for hardcoded Chinese text.

/i18n-check <module> [options]

Modules: main, live2d, voice, steam, settings, chat, custom

Options: --status, --reset, --files=<path>, --html, --js, --strict

See references/check-modules.md for module file mappings.

2. i18n-fix - Fix Issues

Replace hardcoded Chinese with i18n markers.

/i18n-fix <module> [--add-keys]

Fix patterns:

  • HTML: Add data-i18n="key" attributes
  • JS: Use window.t('key') with fallback

See references/fix-patterns.md for examples.

3. i18n-sync - Sync Languages

Align translation keys across all languages.

uv run python scripts/i18n_sync.py          # Check status
uv run python scripts/i18n_sync.py --apply  # Apply changes

Quick Workflow

  1. Check: /i18n-check steam - Find hardcoded strings
  2. Fix: /i18n-fix steam - Replace with i18n markers
  3. Verify: /i18n-check steam - Confirm fixes
  4. Sync: /i18n-sync - Sync to other languages

Detection Rules

Check for:

  • HTML: Chinese text in elements or attributes
  • JS: Chinese strings not wrapped in window.t()

Skip:

  • Already has data-i18n* or window.t() wrapper
  • console.log/error/warn debug messages
  • Third-party libs (static/libs/)
  • Comments
  • Internal logic strings (e.g., includes('已离开'))
  • Data keys (e.g., data['档案名'])
Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
