name: localize description: "Generates or updates i18n localization files, translation keys, and locale configurations. Use when adding a new language, updating translation strings, or when the user mentions localization, i18n, translation, or l10n." argument-hint: "[scan|extract|validate|status]" user-invocable: true allowed-tools: Read, Glob, Grep, Write, Bash effort: 1 when_to_use: "When scanning, extracting, or validating localization strings, or checking for hardcoded text in the codebase"

When this skill is invoked:

1. Parse the subcommand from the argument:

   • scan — Scan for localization issues (hardcoded strings, missing keys)
   • extract — Extract new strings and generate/update string tables
   • validate — Validate existing translations for completeness and format
   • status — Report overall localization status

2. For scan:

   • Search src/ for hardcoded user-facing strings:
     • String literals in UI code that are not wrapped in a localization function
     • Concatenated strings that should be parameterized
     • Strings with positional placeholders (%s, %d) instead of named ones ({playerName})
   • Search for localization anti-patterns:
     • Date/time formatting not using locale-aware functions
     • Number formatting without locale awareness
     • Text embedded in images or textures (flag asset files)
     • Strings that assume left-to-right text direction
   • Report all findings with file paths and line numbers

3. For extract:

   • Scan all source files for localized string references
   • Compare against the existing string table (if any) in assets/data/
   • Generate new entries for strings that don't have keys yet
   • Suggest key names following the convention: [category].[subcategory].[description]
   • Output a diff of new strings to add to the string table

4. For validate:

   • Read all string table files in assets/data/
   • Check each entry for:
     • Missing translations (key exists but no translation for a locale)
     • Placeholder mismatches (source has {name} but translation is missing it)
     • String length violations (exceeds character limits for UI elements)
     • Orphaned keys (translation exists but nothing references the key in code)
   • Report validation results grouped by locale and severity

5. For status:

   • Count total localizable strings
   • Per locale: count translated, untranslated, and stale (source changed since translation)
   • Generate a coverage matrix:

   ## Localization Status
   Generated: [Date]
   
   | Locale | Total | Translated | Missing | Stale | Coverage |
   |--------|-------|-----------|---------|-------|----------|
   | en (source) | [N] | [N] | 0 | 0 | 100% |
   | [locale] | [N] | [N] | [N] | [N] | [X]% |
   
   ### Issues
   - [N] hardcoded strings found in source code
   - [N] strings exceeding character limits
   - [N] placeholder mismatches
   - [N] orphaned keys (can be cleaned up)
   

Rules

• English (en) is always the source locale
• Every string table entry must include a translator comment explaining context
• Never modify translation files directly — generate diffs for review
• Character limits must be defined per-UI-element and enforced automatically
• Right-to-left (RTL) language support should be considered from the start, not bolted on later
