+# Jules Scheduled Task - UI/UX Enhancement Agent
+
+## Agent Identity
+You are an autonomous UI/UX enhancement agent for the Splitwiser expense-splitting application. Your task is to make **super minor, incremental improvements** to the codebase while maintaining perfect backwards compatibility.
+
+---
+
+## Project Context
+
+### Tech Stack
+- **Web App** (`/web`): React + Vite + TypeScript + TailwindCSS + Framer Motion
+  - Uses dual theming system: `GLASSMORPHISM` and `NEOBRUTALISM`
+  - Components in `/web/components/ui/` (Button, Card, Input, Modal, Skeleton)
+  - Pages in `/web/pages/` (Auth, Dashboard, Groups, GroupDetails, Friends, Profile)
+  - Context providers for Auth and Theme
+  
+- **Mobile App** (`/mobile`): Expo/React Native + React Native Paper
+  - Screens in `/mobile/screens/`
+  - Navigation in `/mobile/navigation/`
+  - API services in `/mobile/api/`
+
+### Design Philosophy
+- Web uses modern design with two switchable themes (glassmorphism for elegance, neobrutalism for bold)
+- Mobile uses React Native Paper with Material Design principles
+- Both prioritize accessibility and responsive design
+
+---
+
+## Your Task Instructions
+
+### CRITICAL: Before Making ANY Changes
+
+1. **Verify Project Tooling** (DO THIS FIRST!)
+   ```bash
+   # Check package.json to determine package manager
+   # Look for package-lock.json (npm), yarn.lock (yarn), or pnpm-lock.yaml (pnpm)
+   # This project uses: npm (confirmed by package-lock.json presence)
+   ```
+   
+   **Available Commands for Splitwiser:**
+   - `cd web && npm install && npm run dev` - Start web dev server
+   - `cd mobile && npm install && npx expo start` - Start mobile app
+   - `cd backend && pip install -r requirements.txt && uvicorn main:app --reload` - Start backend
+   - **DO NOT use pnpm or yarn** - this project uses npm and pip
+
+2. **Understand Project Direction**
+   - Read `README.md` for project vision
+   - Check recent commits to understand current focus
+   - Review open issues/PRs to see what's being prioritized
+   - Splitwiser goal: Modern, user-friendly expense splitting with dual-theme support
+
+3. **Read the tracking files** in `.Jules/`:
+   - `knowledge.md` - Understand past learnings and avoid repeating mistakes
+   - `todo.md` - Check for queued tasks to pick up
+   - `changelog.md` - Review recent changes for context
+
+4. **Analyze current state** of `web/` and `mobile/` folders
+

+
+---
+
+## Code Quality Rules
+
+### DO
+- Make changes **meaningful but focused** (impactful but not sprawling)
+- **Verify tooling first** - Check package.json/lock files before assuming commands
+- Test that existing functionality still works
+- Follow existing code patterns and style
+- Add comments only when logic is complex
+- Use existing color tokens from `tailwind.config.js` and `constants.ts`
+- Preserve dual-theme support in web components
+- **Align with project direction** - Changes should move the project forward
+
+### DON'T
+- Make trivial changes that users won't notice (e.g., only renaming a variable)
+- **Assume tooling** - Never use pnpm/yarn without verifying the project uses them
+- Refactor large sections of code
+- Change APIs or data structures
+- Remove existing functionality
+- Add new dependencies without documenting in `knowledge.md`
+- Make changes that require database migrations
+- Break backwards compatibility
+- Make changes just for the sake of making changes
+
+---
+
+## Example Task Execution
+
+### Task: Add aria-label to icon-only Button in Sidebar
+
+**1. Identify the issue:**
+```tsx
+// Current (in Sidebar.tsx)
+<Button size="sm" variant="secondary" onClick={toggleMode}>
+  {mode === 'dark' ? <Sun size={18} /> : <Moon size={18} />}
+</Button>
+```
+
+**2. Apply fix:**
+```tsx
+// Fixed
+<Button 
+  size="sm" 
+  variant="secondary" 
+  onClick={toggleMode}
+  aria-label={mode === 'dark' ? 'Switch to light mode' : 'Switch to dark mode'}
+>
+  {mode === 'dark' ? <Sun size={18} /> : <Moon size={18} />}
+</Button>
+```
+
+**3. Update tracking files:**
+
+`todo.md` - Check off completed task, note any related tasks discovered
+
+`knowledge.md` - Document if any challenges encountered
+
+`changelog.md` - Log the change with date
+
+---
+
+## Validation Checklist

+Before committing any change, verify:
+- [ ] No TypeScript/ESLint errors in web
+- [ ] No React Native errors in mobile
+- [ ] Visual appearance unchanged (or improved)
+- [ ] Both themes work correctly (web)
+- [ ] Dark mode works correctly
+- [ ] No console errors or warnings
+- [ ] Tracking files updated
+- [ ] **Change is meaningful** - Users will notice and appreciate it
+- [ ] **Correct tooling used** - Verified package manager from package.json
+- [ ] **Aligns with project direction** - Improves expense-splitting UX
+
+---
+
+## Learning from Past Mistakes
+
+### ❌ Mistake 1: Assuming Tooling Without Verification
+**What Happened:** Previous agent used `pnpm` commands when project uses `npm`
+**Why It Failed:** Didn't check package.json or lock files
+**Fix:** Always verify tooling first - check for package-lock.json (npm), yarn.lock (yarn), pnpm-lock.yaml (pnpm)
+
+### ❌ Mistake 2: Changes Too Trivial/Insignificant  
+**What Happened:** Made tiny changes users didn't notice (e.g., single ARIA label)
+**Why It Failed:** Overly cautious "under 50 lines" limit led to meaningless changes
+**Fix:** Aim for 30-100 lines of focused, impactful change. Each commit should be noticeable.
+
+### ❌ Mistake 3: Not Aligned with Project Direction
+**What Happened:** Made generic UX improvements without understanding project goals
+**Why It Failed:** Didn't read project vision or recent development trajectory
+**Fix:** Check README, recent commits, and understand that Splitwiser is about modern expense-splitting with exceptional UX
+
+### ✅ What Good Changes Look Like
+- Add complete skeleton loading system to Dashboard (not just one skeleton)
+- Implement full pull-to-refresh with haptic feedback (not just the gesture)
+- Create comprehensive empty state with illustration + CTA (not just text)
+- Add entire toast notification system for user feedback
+- Implement keyboard navigation for whole page (not just one element)
+
+---
+
+## Session Start Protocol
+
+1. **Verify tooling** - Check package.json and lock files to confirm npm/yarn/pnpm
+2. **Check project direction** - Review recent commits and README for current focus
+3. Pull latest code from main branch
+4. Read `.Jules/knowledge.md` for context and past mistakes
+5. Read `.Jules/todo.md` for queued tasks
+6. **Pick ONE meaningful task** that:
+   - Users will actually notice and appreciate
+   - Aligns with project direction (expense-splitting UX excellence)
+   - Takes 30-100 lines of focused change (not too trivial, not too large)
+7. Make the change and verify it works
+8. Update all three tracking files
+9. Commit with descriptive message: `[jules] Brief description of change`
+
+**Red Flags (Stop and Reassess):**
+- Using commands not in package.json
+- Change feels too trivial (just renaming, adding one ARIA label)
+- Change doesn't relate to expense-splitting experience
+- Unclear if change improves user experience
+
+---
+
+## Commit Message Format
+
+```
+[jules] <type>: <brief description>
+
+<type> = fix | enhance | a11y | style | perf
+```
+
+Examples:
+- `[jules] a11y: Add aria-labels to Sidebar icon buttons`
+- `[jules] enhance: Add skeleton loader to Groups page`
+- `[jules] fix: Correct Input focus ring in dark mode`
+- `[jules] style: Improve Card hover animation timing`

+# Jules Knowledge Base
+
+> Learnings, patterns, and solutions discovered while working on Splitwiser UI/UX.
+
+---
+
+## Project Architecture
+
+### Web Application Structure
+**Date:** 2026-01-01
+**Context:** Initial codebase analysis
+
+The web app follows a clean architecture:
+```
+web/
+├── App.tsx           # Main router with protected routes
+├── components/
+│   ├── layout/       # Layout, Sidebar, ThemeWrapper
+│   └── ui/           # Reusable: Button, Card, Input, Modal, Skeleton
+├── contexts/         # AuthContext, ThemeContext
+├── pages/            # Route pages
+├── services/         # API calls
+├── constants.ts      # Theme constants (GLASSMORPHISM, NEOBRUTALISM)
+└── types.ts          # TypeScript interfaces
+```
+
+### Mobile Application Structure
+**Date:** 2026-01-01
+**Context:** Initial codebase analysis
+
+The mobile app uses Expo with React Navigation:
+
+```
+mobile/
+├── App.js            # Entry point with providers
+├── screens/          # All screen components
+├── navigation/       # Stack and Tab navigators
+├── context/          # AuthContext
+├── api/              # API client and service functions
+└── utils/            # Helpers (currency, balance calculations)
+
+---
+
+## Theming System
+
+### Web Dual-Theme Pattern
+**Date:** 2026-01-01
+**Context:** Understanding theme-switching mechanism
+
+The web app supports two themes controlled by `ThemeContext`:
+- **GLASSMORPHISM**: Modern, translucent look with blurs and gradients
+- **NEOBRUTALISM**: Bold, sharp design with hard shadows and borders
+
+**How to implement:**
+```tsx
+const { style, mode } = useTheme();
+const isNeo = style === THEMES.NEOBRUTALISM;
+
+// Apply conditional classes
+className={isNeo 
+  ? 'border-2 border-black rounded-none shadow-[4px_4px_0px_0px_rgba(0,0,0,1)]' 
+  : 'rounded-xl backdrop-blur-md border-white/20'
+}
+```
+
+**Important:** Always support BOTH themes when modifying UI components.
+
+### Color Tokens
+
+**Date:** 2026-01-01
+**Context:** Custom colors in tailwind.config.js
+
+```js
+colors: {
+  neo: {
+    main: '#8855ff',    // Primary purple
+    second: '#ff9900',  // Secondary orange
+    accent: '#00cc88',  // Accent green
+    bg: '#f0f0f0',      // Background light
+    dark: '#1a1a1a'     // Background dark
+  }
+}
+```
+
+---
+
+## Component Patterns
+
+### Button Component Variants
+
+**Date:** 2026-01-01
+**Context:** Understanding Button.tsx API
+
+```tsx
+<Button 
+  variant="primary|secondary|danger|ghost"
+  size="sm|md|lg"
+  onClick={handler}
+  disabled={boolean}
+  className="additional classes"
+>
+  Content
+</Button>
+```
+
+### Card Component with Title/Action
+
+**Date:** 2026-01-01
+**Context:** Card.tsx supports optional header
+
+```tsx
+<Card 
+  title="Optional Title"
+  action={<Button>Action</Button>}
+  className="additional"
+>
+  {children}
+</Card>
+```
+
+### Modal Component Pattern
+
+**Date:** 2026-01-01
+**Context:** Modal.tsx structure
+
+```tsx
+<Modal
+  isOpen={boolean}
+  onClose={handler}
+  title="Modal Title"
+  footer={<>Cancel and Submit buttons</>}
+>
+  {content}
+</Modal>
+```
+
+---
+
+## Mobile Patterns
+
+### React Native Paper Components
+
+**Date:** 2026-01-01
+**Context:** Primary UI library for mobile
+
+Commonly used components:
+- `<Card>` with `<Card.Title>` and `<Card.Content>`
+- `<Avatar.Image>` and `<Avatar.Text>`
+- `<Button mode="contained|outlined|text">`
+- `<TextInput>` with label, value, onChangeText
+- `<FAB>` for floating action buttons
+- `<Portal>` and `<Modal>` for overlays
+- `<ActivityIndicator>` for loading states
+
+### Safe Area Pattern
+
+**Date:** 2026-01-01
+**Context:** Screens use View without SafeAreaView
+
+Most screens use `<View style={{ flex: 1 }}>` - consider wrapping in `SafeAreaView` for notched devices.
+
+---
+
+## API Response Patterns
+
+### Groups API
+
+**Date:** 2026-01-01
+**Context:** Group data structure from backend
+
+```typescript
+interface Group {
+  _id: string;
+  name: string;
+  currency: string;
+  joinCode: string;
+  imageUrl?: string;
+  members: GroupMember[];
+  createdAt: string;
+}
+```
+
+### Balance Summary API
+
+**Date:** 2026-01-01
+**Context:** Dashboard balance data
+
+```typescript
+interface BalanceSummary {
+  totalOwedToYou: number;
+  totalYouOwe: number;
+  netBalance: number;
+  groupsSummary: GroupBalanceSummary[];
+}
+```
+
+---
+
+## Known Issues & Gotchas
+
+### Image URL Validation
+
+**Date:** 2026-01-01
+**Context:** Avatar image handling pattern
+
+Both web and mobile use this pattern to validate image URLs:
+```javascript
+const isImage = imageUrl && /^(https?:|data:image)/.test(imageUrl);
+```
+
+Always check before rendering `<img>` or `<Avatar.Image>`.
+
+### Currency Formatting
+
+**Date:** 2026-01-01
+**Context:** Mobile uses utility, web uses inline
+
+- Mobile: Uses `formatCurrency()` and `getCurrencySymbol()` from `utils/currency.js`
+- Web: Uses inline template literals like `${group.currency} ${amount.toFixed(2)}`
+
+**Consider:** Standardizing currency formatting across platforms.
+
+### Framer Motion in Web
+
+**Date:** 2026-01-01
+**Context:** Animation library usage
+
+Common patterns:
+
+```tsx
+<motion.div
+  initial={{ opacity: 0, y: 20 }}
+  animate={{ opacity: 1, y: 0 }}
+  whileHover={{ scale: 1.02 }}
+  transition={{ type: 'spring', stiffness: 100 }}
+/>
+```
+
+Use `AnimatePresence` for exit animations.
+
+---
+
+## Best Practices Learned
+
+### 1. Accessibility First
+
+Always add:
+- `aria-label` for icon-only buttons
+- `role` attributes for non-semantic elements
+- `tabIndex` for keyboard navigation
+- Focus styles for keyboard users
+
+### 2. Loading State Hierarchy
+
+1. Full-screen skeleton for initial load
+2. Inline loading for actions
+3. Optimistic updates where possible
+
+### 3. Error Handling
+
+1. Try/catch API calls
+2. Show user-friendly error messages
+3. Log errors for debugging
+4. Provide retry options
+
+### 4. Responsive Breakpoints
+
+Tailwind breakpoints used:
+- `sm`: 640px
+- `md`: 768px
+- `lg`: 1024px
+- `xl`: 1280px
+
+---
+
+## Errors Encountered & Solutions
+
+### Previous Agent Mistakes (Lessons Learned)
+
+**Date:** 2026-01-01
+**Context:** Learning from past "Palette" agent that didn't work well
+
+**Mistake 1: Wrong Package Manager**
+
+- **Error:** Agent used `pnpm` commands when project uses `npm`
+- **Root Cause:** Didn't verify tooling from package.json/lock files
+- **Solution:** Always check for package-lock.json (npm), yarn.lock (yarn), or pnpm-lock.yaml (pnpm) FIRST
+- **Verification:** `ls package*.json` and check for lock files
+
+**Mistake 2: Changes Too Trivial**
+
+- **Error:** Made insignificant changes like single ARIA labels that users didn't notice
+- **Root Cause:** Over-cautious approach with "under 50 lines" hard limit
+- **Solution:** Aim for 30-100 lines of meaningful, focused change. Each commit should be user-noticeable.
+- **Example of Good Change:** Implement complete skeleton loading system, not just one skeleton
+
+**Mistake 3: Misaligned with Project Direction**
+
+- **Error:** Made generic UX improvements without understanding Splitwiser's goals
+- **Root Cause:** Didn't read README or understand project trajectory
+- **Solution:** Check README, recent commits, issues. Understand Splitwiser = modern expense-splitting with dual-theme excellence
+
+**Files to Check Before Starting:**
+
+- `README.md` - Project vision
+- `package.json` - Available scripts and tooling
+- `.git/logs/HEAD` or recent commits - Development direction
+
+---
+
+## Project Direction & Goals
+
+### What Splitwiser Is About
+
+**Date:** 2026-01-01
+
+Splitwiser is focused on (per README):
+1. **Modern expense splitting** - Making group expenses effortless
+2. **Group management** - Create and manage expense groups
+3. **Real-time synchronization** - Keep data synced across devices
+4. **Secure authentication** - JWT-based auth with refresh tokens
+5. **Receipt management** - Track and store receipt images
+6. **Debt simplification** - Minimize number of transactions
+7. **Multi-currency support** - Handle different currencies
+8. **Exceptional UX** - Beautiful, intuitive, delightful interactions
+9. **Cross-platform** - Web (React/Vite/TypeScript) and mobile (Expo/React Native)
+
+**Current Implementation Details:**
+- Web app uses dual-theme design system (Glassmorphism & Neobrutalism)
+- Mobile uses React Native Paper (Material Design)
+- Backend: FastAPI + MongoDB
+
+**NOT focused on:**
+- Generic business app features
+- Traditional accounting workflows
+- Enterprise features
+- One-off utilities
+
+**When picking tasks, ask:**
+- Does this improve expense splitting experience?
+- For web: Does it work in BOTH themes?
+- Will users notice and appreciate this?
+- Does it align with the README's core features?
