Localization Manager
Overview
Automate the full i18n workflow—from detecting missing translation keys and generating AI-assisted translations to syncing locale files across codebases and validating translation quality.
When to Use
- Detecting untranslated strings after new feature development
- Generating initial AI translations for a new language
- Syncing translation files between frontend repo and CMS
- Auditing translation completeness before a product launch
- Managing translation contributor workflows with review queues
Instructions
- Accept inputs: source language, target languages, locale files directory, translation provider (AI/human/both), sync targets (CMS, S3, etc.).
- Scan codebase for all i18n keys (t(), $t(), useTranslation patterns).
- Compare extracted keys against existing locale files to find: missing keys, unused keys, inconsistent pluralization.
- For missing keys: generate AI translations using configured LLM or translation API (DeepL, Google Translate).
- Flag translations that may need human review (long text, legal terms, marketing copy).
- Validate translations: check for placeholder mismatches (%s, {name}), HTML tag consistency, character limit violations.
- Write updated locale files and create a PR with changes.
- Return audit report: coverage percentage per language, new keys translated, keys needing review.
