I18n Expert

daymade/claude-code-skills

If you're adding i18n to a React/Next/Vue codebase or auditing one that's half-done, this skill walks through the full cycle: install and configure react-i18next or the framework equivalent, hunt down hardcoded strings with regex, replace them with translation keys, ensure en-US and zh-CN parity, and localize error messages so users never see raw error.message. It includes a Python audit script to catch missing keys and dynamic translation calls. The workflow is opinionated about namespace structure, pluralization, and treating missing translations as blockers. Useful if you need comprehensive i18n coverage and want to avoid the usual pitfalls like exposing English-only errors or breaking tests that assert on visible text.

I18n Expert

Overview

Deliver a complete i18n setup + audit pass: configure the i18n framework, replace user-facing strings with keys, ensure locale parity, and validate pluralization/formatting for en-US and zh-CN.

Core Capabilities

  • Library selection and setup (React, Next.js, Vue).
  • Key architecture and locale file organization.
  • Translation generation and quality strategy (AI, professional, manual).
  • Routing and language detection/switching.
  • SEO and metadata localization (when applicable).
  • RTL support (only if RTL locales are in scope).

Scope Inputs (ask if unclear)

  • Framework and routing style.
  • Existing i18n state (none, partial, legacy).
  • Target locales (default: en-US + zh-CN).
  • Translation quality needs (AI vs professional vs manual).
  • Locale formats in use (JSON, YAML, PO, XLIFF).
  • Formality/cultural requirements (if any).

Workflow (Audit -> Fix -> Validate)

  1. Confirm scope and locale targets
  • Identify the i18n framework and locale locations.
  • Confirm locales; default to en-US + zh-CN when specified.
