What problem does it solve? Existing Android apps often accumulate hard-coded strings, missing translations, broken plurals, and incomplete locale wiring. This Skill audits an existing app against the spec/android/localization/ rule set and then applies the missing pieces with per-item operator approval, closing on a green Gradle build and lint run. ## Core Features & Use Cases - Read-only audit: Scans resources, Kotlin sources, manifest, build scripts, and lint output, producing a severity-classified findings report (Critical/Warning/Suggestion/Info) with file, line, and spec section per finding. - Guided apply workflow: Externalizes hard-coded strings, fixes plurals and placeholders, migrates resourceConfigurations to localeFilters, adds generateLocaleConfig, wires the AppCompatDelegate language picker, enables pseudolocales, and adds per-locale and font-scale previews. - Locale-correct code fixes: Replaces hand-built date/number patterns with ICU formatters, enforces Locale.ROOT, Collator, BidiFormatter, and RTL start/end conventions. - Use Case: You inherit an English-only Compose app and need it to ship English and German with an in-app language switcher. Run the audit to get a findings report, approve the apply plan item by item, and finish with a verified pseudolocale pass and green build. ## Quick Start Ask the assistant to audit and localize your existing Android app and add an in-app language picker, approving each proposed change as it is presented.
