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 5.1 | $0.00077 | $0.01576 |
| Opus 5 | $0.00039 | $0.00788 |
| Sonnet 5 | $0.00015 | $0.00315 |
| Haiku 4.5 | $0.00008 | $0.00158 |
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 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.
How it starts
The opening of the file, as written. The whole thing — 181 lines — stays where its author put it; the contents beside it link to each section on GitHub.
i18n Specialist
Expert in setting up and maintaining internationalization. Each app manages its own translations independently.
Mandatory Standards (Apply When Scaffolding Any App)
- Default locale:
en— types and catalogs are generated fromen; runtime falls back toenfor missing keys or unknown locale. - Standard second locale:
tr— for every deployable app or service that shows user-visible text, shipen+trmessage files together unless the product spec explicitly excludes Turkish. App/folder names in docs are examples only (web,admin,api, etc. — use whatever the repo actually has). - No static user-facing strings in code — anything a real user or API client reads (errors, validation messages, emails, UI) goes through the translation layer (
t,getApiTranslation, etc.). Exception: dummy/sample/fixture/seed/test-only strings that never ship as real product copy may stay literals.
API locale: derive from Accept-Language, authenticated user preference, or a documented query/header; if absent or unsupported, use en.
Core Principle: Per-App Translation Ownership
Every app owns its own translation files. Translations are NEVER shared across apps via a common package. Each app has different UI, different contexts, and different strings.
# Illustrative names only — match your monorepo’s actual apps
apps/
<api>/messages/
en.json
tr.json
<web-or-storefront>/messages/
en.json
tr.json
<dashboard-or-console>/messages/

tr.json
packages/
i18n/ ← ONLY config + types + helpers (NO translation JSON)
src/
config.ts ← Supported locales, default locale
types.ts ← Shared type definitions
helpers.ts ← Date/number/currency formatting helpers
Why Per-App?
- Web says "Save changes" → Admin says "Save" → Mobile says "Done" — same action, different copy
- API error messages are technical, frontend messages are user-friendly
- Each app ships its own bundle — shared translations bloat unused apps
- Teams can work on translations independently without merge conflicts
What ships with it
1 file 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.
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.

i18n-specialist is a skill published in the GitHub repository mtnyilmaz/agents (6 stars, last pushed 3mo ago), licensed MIT. It adds 77 tokens to every session and 1,576 once invoked, about $0.0004 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.
