i18n-tools

Code-aware UI localization readiness analysis. Given a web app's source code, it produces the plan you need before translating: a string inventory traced to where each string is used, a terminology/glossary draft (plus a critical-strings register for destructive/billing/legal copy), and — the part a string catalog can't show — the structural blockers that break a translation even when every string is translated perfectly:

• styling or logic derived from display text (e.g. a switch on text[0])
• layout/sizing tuned to source-language string lengths
• font/script coverage gaps (no glyphs for the target script)
• RTL hazards (no dir, physical-side CSS, un-mirrored icons)
• locale loading & registration bugs (code↔dir mismatches, date libs not registered per locale)
• hand-built number/date/money formatting and naive interpolation/pluralization

It produces an analysis/plan, not the finished translations — the deliverable that makes the eventual translation safe and consistent.

Skill (once installed): i18n-tools:ui-localization. It also triggers on its own when you ask to translate/localize/i18n an app, add a locale, add RTL support, audit i18n readiness, or when a translation "looks broken" in a specific language.

The plugin bundles a helper script, scripts/i18n-sweep.sh <app-source-dir>, which greps the whole structural-blocker catalog at once (with per-category triage counts).
