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 5.1 | $0.00067 | $0.00867 |
| Opus 5 | $0.00034 | $0.00434 |
| Sonnet 5 | $0.00013 | $0.00173 |
| Haiku 4.5 | $0.00007 | $0.00087 |
Grade A, and why
i18n-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 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.

i18n / Localization
Purpose
Treat language as a first-class platform. Set up the i18n pipeline early so strings are extracted, translated, and verified per locale instead of being patched after release. Cover RTL, CJK, plurals, currency, dates, names, voice, and culture-specific imagery — not only word-for-word translation.
Product context
- Read
references/i18n-pipeline.md. - Pull the platform matrix from
platform-detectorand the UX specs fromux-design. - Pick the locale matrix: source locale + target locales + fallback chain. Justify each addition.
- Use Context7 MCP for current ICU MessageFormat behavior, current platform i18n APIs (Apple Foundation, Android Resources, Web Intl, .NET globalization), and current translation-platform integrations.
Design and validation
- Extract strings. All visible strings into string tables (Apple
.strings/.stringsdict, Androidstrings.xml/plurals.xml, web.json/.po/.xliff, UnityLocalizedString, UnrealStringTable). No hardcoded strings. - Translator brief. Per project: tone, voice, glossary, do-not-translate list, character limits per string, screenshots/context.
- Plural and gender rules. Use ICU MessageFormat (or platform equivalent) instead of string concatenation. Verify against CLDR plural categories per language.
- RTL and CJK. Verify mirroring of layout for RTL (Arabic, Hebrew, Persian, Urdu) and font glyph coverage for CJK (Chinese, Japanese, Korean). Test wide-text expansion for German, Russian, Finnish.
- Locale-specific formats. Date, time, number, currency, name order, address format, calendar — use platform formatters, not custom strings.
- Voice / video. If the product has voice, plan voice-over recording per locale; if video, plan subtitles per locale.
- Store listings. Translate store metadata: title, subtitle, description, screenshots with locale-specific copy where needed.
- Locale QA. Per locale: pseudo-localized run (
Ļöċäľïżëď ŧëẍŧ), expansion check, missing-string check, RTL check, fallback-chain check. - Release-gate verdict. Go / Conditional / Hold per locale.
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.
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-localization is a skill published in the GitHub repository ashermahonin/agentic-skills (10 stars, last pushed 16d ago), licensed MIT. It adds 67 tokens to every session and 867 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.
