i18n - Localization & UX Writing

Ensure all user-facing text is localized and crystal clear. Every string should be understandable by a 10-year-old or non-native English speaker.

When to Use This Skill

Checking for hardcoded strings
Writing or improving user-facing text
Creating error messages, button labels, confirmations
Migrating strings to i18n files
Reviewing string quality

Quick Reference

The Golden Rules

Be specific, not vague - "Could not save photo" not "Error occurred"
Use plain words - "Sign in" not "Authenticate"
Buttons complete "I want to ___" - "Delete photo" not "OK"
Errors say what to do - "Check your connection and try again"
No confusing dialogs - Never [Cancel] [OK] on a cancel confirmation

Commands

# Audit for hardcoded strings
dart run .claude/skills/i18n/scripts/check.dart --audit

# Audit specific feature
dart run .claude/skills/i18n/scripts/check.dart --audit auth

# Generate missing i18n files
dart run .claude/skills/i18n/scripts/check.dart --generate

# Regenerate translations
dart run build_runner build --delete-conflicting-outputs

Workflow

1. Audit

dart run .claude/skills/i18n/scripts/check.dart --audit {feature}

Look for: Text('...'), title:, hintText:, label:, SnackBar messages, Dialog content.

2. Evaluate & Improve

Check each string against ux-writing-guide.md. Use patterns from examples.md.

3. Add to i18n File

Create/update lib/features/{feature}/i18n/{feature}.i18n.yaml with proper strings.

4. Replace in Code

// Before: Text('Welcome back')
// After:  Text(t.auth.login.title)

5. Regenerate

dart run build_runner build --delete-conflicting-outputs
