translation-add-language

What problem does it solve? Adding a new language to a software project normally requires manually creating locale files, copying every source key, translating each string, and updating configuration. This Skill automates that entire onboarding workflow in one step. ## Core Features & Use Cases - Language Validation: Resolves full language names to BCP-47 codes (e.g., "Japanese" to "ja") and detects duplicates before creating files. - Automatic File Creation: Matches the project's existing translation file patterns (flat JSON, per-language directories, or module-based layouts) and formats (JSON, YAML, PO). - AI Translation or Empty Templates: Translates all source keys while preserving variables, or generates empty values with the --empty flag for human translators. - Config Updates: Adds the new language to targetLanguages in .translation-sync.json. - Use Case: A developer wants to ship their app in Japanese. They invoke the Skill with "ja", and it creates src/i18n/ja.json with all 142 keys translated, variables preserved, and the config updated. ## Quick Start Add Japanese as a new target language to this project and translate all keys from the English source file.
