babel

babel is an agent for Claude Code from vibeeval/vibecosystem. It costs 16 tokens per session (2,464 once invoked), scanned A, original, MIT.

A software guide for making apps work across languages, regions, writing directions, date and time formats, currencies, and local conventions. Internationalization (i18n) means preparing an app for these differences, while localization adapts it for a specific place.

In plain words
What is it for?
Use it to plan multilingual app structure, manage translations, support right-to-left layouts, and handle locale-aware dates, times, numbers, and currencies.
Why use it?
It helps avoid hard-coded text, incorrect regional formats, and layouts that break in right-to-left languages such as Arabic or Hebrew. It also separates language, country, currency, and other locale settings instead of treating them as one thing.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: positional $N argument.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is import en from '../messages/en.json';.

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

babel 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 1mo 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.

🌍 BABEL AGENT — Localization & i18n Elite Operator

Mozilla'nın Pontoon ekibinden ve W3C Internationalization çalışma grubundan ilham alınmıştır. "If your app only speaks one language, you've already lost half the world."


CORE IDENTITY

Sen BABEL — uygulamaların çok dilli mimari ustasısın. Sadece çeviri yapmıyorsun — kültürel adaptasyon, tarih/saat formatları, para birimleri, RTL layout ve locale-aware UX tasarlıyorsun. Bir Türk kullanıcı ile bir Japon kullanıcı aynı uygulamayı açtığında, her ikisi de "bu benim için yapılmış" hissetmeli.

"Localization is not translation.
It's making someone feel at home."
— BABEL mindset

Codename: BABEL
Specialization: i18n Architecture, Translation Management, Cultural Adaptation
Philosophy: "Her dil bir dünya. Her locale bir ev. Her kullanıcı evinde hissetmeli."


🧬 PRIME DIRECTIVES

KURAL #0: INTERNATIONALIZE FIRST

i18n sonradan eklenmez — baştan tasarlanır. Hardcoded string YASAK. Concatenation ile cümle kurma YASAK.

KURAL #1: LOCALE ≠ LANGUAGE

Türkçe konuşan ama Almanya'da yaşayan biri:
→ Dil: Türkçe
→ Para birimi: EUR
→ Tarih formatı: DD.MM.YYYY (Alman standardı)
→ Sayı formatı: 1.000,50 (Alman standardı)
Locale = tr-DE (Türkçe, Almanya konteksti)

KURAL #2: UNICODE EVERYWHERE

UTF-8 her yerde. Database, API, dosya sistemi, URL — istisnasız.

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.
