Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00062 | $0.02914 |
| Opus 5 | $0.00031 | $0.01457 |
| Sonnet 5 | $0.00012 | $0.00583 |
| Haiku 4.5 | $0.00006 | $0.00291 |
Grade A, and why
nylo-localization 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 2d 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.

Nylo Localization
Overview
Nylo v7 provides a JSON-based localization system configured in lib/config/localization.dart. Translation files live in the lang/ directory, and strings are accessed throughout the app using the .tr() extension or the TextTr convenience widget.
When to Use
- Adding multi-language (i18n) support to a Nylo project
- Creating or editing JSON translation files
- Displaying translated text with
Text.tr,TextTr, or.tr() - Passing dynamic arguments into translated strings
- Switching languages at runtime (programmatically or via LanguageSwitcher widget)
- Configuring supported locales, default locale, or fallback locale
- Handling right-to-left (RTL) languages like Arabic or Hebrew
- Debugging missing translation keys
- When NOT to use: For theming or styling text appearance unrelated to language, use nylo-themes instead
Quick Reference
| Action | Code / Location |
|---|---|
| Translation files directory | lang/en.json, lang/es.json, etc. |
| Localization config | lib/config/localization.dart |
| Set default locale | DEFAULT_LOCALE=en in .env |
| Use device locale | LOCALE_TYPE=device in .env |
| Debug missing keys | DEBUG_TRANSLATIONS=true in .env |
| Translate a string | "welcome".tr() |
| Translate with args | "greeting".tr(arguments: {"name": "John"}) |
| Translate nested key | "navigation.home".tr() |
| TextTr widget | TextTr("welcome") |
| TextTr with args | TextTr("greeting", arguments: {"name": "John"}) |
| Switch language (NyPage) | changeLanguage('es') |
| Switch language (anywhere) | await NyLocalization.instance.setLanguage(context, language: 'es') |
| Check if RTL | LocalizationConfig.isRtl(languageCode) |
| Verify key exists | NyLocalization.instance.hasTranslation("key") |
| Get all loaded keys | NyLocalization.instance.getAllKeys() |
| Rebuild env after changes | metro make:env --force |
Project Setup
1. Create Language Files
Add JSON files to the lang/ directory at the project root. Each file is named by its locale code:
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.

nylo-localization is a skill published in the GitHub repository nylo-core/claude-code (4 stars, last pushed 4mo ago), licensed MIT. It adds 62 tokens to every session and 2,914 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
