+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+HabitTrove is a gamified habit tracking PWA built with Next.js 15, TypeScript, and Jotai state management. Users earn coins for completing habits and can redeem them for rewards. Features multi-user support with admin capabilities and shared ownership of habits/wishlist items.
+
+## Essential Commands
+
+### Development
+- `npm run dev` - Start development server with Turbopack
+- `npm run setup:dev` - Full setup: installs bun, dependencies, runs typecheck and lint
+- `npm install --force` - Install dependencies (force flag required)
+
+### Quality Assurance (Run these before committing)
+- `npm run typecheck` - TypeScript type checking (required)
+- `npm run lint` - ESLint code linting (required)
+- `npm test` - Run tests with Bun
+- `npm run build` - Build production version
+
+### Docker Deployment
+- `npm run docker-build` - Build Docker image locally
+- `docker compose up -d` - Run with docker-compose (recommended)
+- Requires `AUTH_SECRET` environment variable: `openssl rand -base64 32`
+
+## Version Management
+
+### Creating a New Version
+1. Update version in `package.json`
+2. Update `CHANGELOG.md` with new version and changes (follow existing patterns in the file, keep entries concise - ideally 1 line per change)
+3. Run `npm run typecheck && npm run lint` to ensure code quality
+4. Commit changes: `git add . && git commit -m "feat: description"`
+  * Follow Conventional Commits Standard: `<type>[scope]: <description>` (e.g., `feat(auth): add OAuth integration`, `fix: resolve memory leak in task loader`).
+
+## Architecture Overview
+
+### State Management (Jotai)
+- **Central atoms**: `habitsAtom`, `coinsAtom`, `wishlistAtom`, `usersAtom` in `lib/atoms.ts`
+- **Derived atoms**: Computed values like `dailyHabitsAtom`, `coinsBalanceAtom`
+- **Business logic hooks**: `useHabits`, `useCoins`, `useWishlist` in `/hooks`
+
+### Data Models & Ownership
+- **Individual ownership**: `CoinTransaction` has single `userId`
+- **Shared ownership**: `Habit` and `WishlistItemType` have `userIds: string[]` array
+- **Admin features**: Admin users can view/manage any user's data via dropdown selectors
+- **Data persistence**: JSON files in `/data` directory with automatic `/backups`
+
+### Key Components Structure
+- **Feature components**: `HabitList`, `CoinsManager`, `WishlistManager` - main page components
+- **Modal components**: `AddEditHabitModal`, `AddEditWishlistItemModal`, `UserSelectModal`
+- **UI components**: `/components/ui` - shadcn/ui based components
+
+### Authentication & Users
+- NextAuth.js v5 with multi-user support
+- User permissions: regular users vs admin users
+- Admin dropdown patterns: Similar implementation across Habits/Wishlist pages (reference CoinsManager for pattern)
+
+### Internationalization
+- `next-intl` with messages in `/messages/*.json`
+- Supported languages: English, Spanish, German, French, Russian, Chinese, Japanese
+
+## Code Patterns
+
+### Component Structure
+```typescript
+// Standard component pattern:
+export default function ComponentName() {
+  const [data, setData] = useAtom(dataAtom)
+  const { businessLogicFunction } = useCustomHook()
+  // Component logic
+}
+```
+
+### Hook Patterns
+- Custom hooks accept options: `useHabits({ selectedUser?: string })`
+- Return destructured functions and computed values
+- Handle both individual and shared ownership models
+
+### Shared Ownership Pattern
+```typescript
+// Filtering for shared ownership:
+const userItems = allItems.filter(item => 
+  item.userIds && item.userIds.includes(targetUserId)
+)
+```
+
+### Admin Dropdown Pattern
+Reference `CoinsManager.tsx:107-119` for admin user selection implementation. Similar pattern should be applied to Habits and Wishlist pages.
+
+## Data Safety
+- Always backup `/data` before major changes
+- Test with existing data files to prevent data loss
+- Validate user permissions for all data operations
+- Handle migration scripts carefully (see PLAN.md for shared ownership migration)
+
+## Performance Considerations
+- State updates use immutable patterns
+- Large dataset filtering happens at hook level
+- Derived atoms prevent unnecessary re-renders

 HabitTrove is a gamified habit tracking application that helps you build and maintain positive habits by rewarding you with coins, which you can use to exchange for rewards.
 
-> **⚠️ Important:** HabitTrove is currently in beta. Please regularly backup your `data/` directory to prevent any potential data loss.
+## Differences to Upstream
 
-## Try the Demo
+I generally try to keep the `main` branch up to date with upstream features, merging tagged versions and mapping them to `<upstream-version>.0`.
 
-Want to try HabitTrove before installing? Visit the public [demo instance](https://demo.habittrove.com) to experience all features without any setup required. (do not store personal info. Data on the demo instance is reset daily)
+In this version I've taken steps to ensure a smoother experience and decreased the chance of the program bricking itself. This doesn't mean that it's completely stable, but I've fixed the most glaring bugs I encountered.
+
+Differences (as of writing) are:
+- resolved linting problems so you can actually commit things
+- added missing dependency
+- refactored adding habit modal to cause less errors
+- resolved undefined error
+- replaced dockerhub release flow with github
+- miscellaneous refactorings
+- split habits & tasks page into two different pages
+- only display "show all" if there are more than 4 entries

+# Language Guide
+
+## Adding/Updating Translations
+
+### Adding a New Language
+
+To add a new language translation to HabitTrove:
+
+1. **Create translation file**: 
+   - Copy `messages/en.json` as a template
+   - Save as `messages/{language-code}.json` (e.g., `ko.json` for Korean)
+   - Translate all values while preserving keys and placeholder variables like `{username}`, `{count}`, etc.
+
+2. **Validate translation structure**:
+   ```bash
+   # Ensure JSON is valid
+   jq empty messages/{language-code}.json
+   
+   # Compare structure with English (should show no differences)
+   diff <(jq -S . messages/en.json | jq -r 'keys | sort | .[]') <(jq -S . messages/{language-code}.json | jq -r 'keys | sort | .[]')
+   ```
+
+3. **Add language option to UI**:
+   - Edit `app/settings/page.tsx`
+   - Add new `<option value="{language-code}">{Language Name}</option>` in alphabetical order
+
+4. **Update documentation**:
+   - Add language to README.md supported languages list
+   - Create new changelog entry with version bump
+   - Update package.json version
+
+### Example: Adding Korean (한국어)
+
+```bash
+# 1. Copy translation file
+cp /path/to/ko.json messages/ko.json
+
+# 2. Add to settings page
+# Add: <option value="ko">한국어</option>
+
+# 3. Update README.md
+# Change: 简体中文, 日본語
+# To: 简체中文, 한국어, 日본語
+
+# 4. Add changelog entry
+# Create new version section with language addition
+
+# 5. Bump package version
+# Update version in package.json
+```
+
+### Translation Quality Guidelines
+
+- Use natural, contextually appropriate expressions
+- Maintain consistent terminology throughout
+- Preserve all placeholder variables exactly: `{username}`, `{count}`, `{target}`, etc.
+- Use appropriate formality level for the target language
+- Ensure JSON structure matches English file exactly (385 total keys)
+
+### Validation Commands
+
+```bash
+# Check JSON validity
+jq empty messages/{lang}.json
+
+# Compare key structure
+node -e "
+const en = require('./messages/en.json');
+const target = require('./messages/{lang}.json');
+// ... deep key comparison script
+"
+
+# Verify placeholder consistency
+grep -o '{[^}]*}' messages/en.json | sort | uniq > en_vars.txt
+grep -o '{[^}]*}' messages/{lang}.json | sort | uniq > {lang}_vars.txt
+diff en_vars.txt {lang}_vars.txt
+```
