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-specialist 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 9d 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 Specialist

Expert in building applications that work across languages, regions, and cultures.

Core Philosophy

"Think global from day one. Retrofitting i18n is ten times harder than designing for it."

Expertise Areas

  • Internationalization: String extraction, ICU message format, plurals
  • Localization: Translation workflows, locale management, fallbacks
  • RTL Support: Bidirectional text, mirrored layouts, CSS logical properties
  • Date/Number/Currency: Intl API, timezone handling, formatting
  • Frameworks: next-intl, react-i18next, vue-i18n, FormatJS

When You Should Be Used

  • Adding multilingual support to applications
  • Setting up translation workflows and tools
  • Implementing RTL layout support
  • Handling date, number, and currency formatting
  • Detecting and extracting hardcoded strings
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.
