i18n Readiness Review

Q: How do I know the i18n Readiness Review output is good?

The skill verifies itself against its own quality checks: Checks string externalization (the #1 blocker) — no hard-coded or concatenated UI text; Verifies locale-aware formatting (Intl/ICU) for dates, numbers, currency, plurals; Assesses layout expansion (+30–40%) and RTL if a target needs it; Confirms UTF-8 / CJK encoding end to end.

🔵 Stable🕐 updated 2026-06-29 🔷 SkillSpec L3 pm-localization

Review a product/codebase for internationalization readiness before you localize. Use when asked if a product is ready to localize, to review i18n readiness, find hard-coded strings/locale bugs, or prep for going multilingual. Produces a readiness audit — externalized strings, locale-aware formatting, layout/expansion, encoding/RTL, and a prioritised list of i18n fixes to make before translation starts.

What to give it

▸The product — web/app/codebase, stack/framework (i18n tooling differs).

▸Target languages — especially if any need RTL (Arabic/Hebrew), CJK (Chinese/Japanese/Korean), or are long (German/Finnish).

▸What you can share — code snippets, UI screenshots, or a description of how strings/formatting are handled today.

✅ The bar it holds itself to

Every skill in this library self-verifies — these are this skill's own quality checks, straight from its definition.

✓Checks string externalization (the #1 blocker) — no hard-coded or concatenated UI text

✓Verifies locale-aware formatting (Intl/ICU) for dates, numbers, currency, plurals

✓Assesses layout expansion (+30–40%) and RTL if a target needs it

✓Confirms UTF-8 / CJK encoding end to end

✓Prioritises blockers to fix *before* translation starts

✓Ends with a clear ready / not-ready verdict

⚠️ What it refuses to do

Do not start translating before i18n is ready — you'll translate into hard-coded strings and broken layouts

Do not concatenate sentence fragments — word order differs by language; translate whole strings with placeholders

Do not string-format dates/numbers — use Intl/ICU, or every locale shows them wrong

Do not assume text length — German/Finnish expand; fixed-width UI truncates and clips

Do not ignore RTL until late — retrofitting right-to-left into a left-to-right layout is a rebuild, not a tweak
