  <action>Create a React component that renders a weekly calendar grid with:
  - 7-day grid layout with day headers
  - Responsive design using Tailwind CSS
  - Proper date formatting for each day
  - Week navigation controls (previous/next buttons)
  - Ability to switch between day and week views
  - Support for displaying 1-14 days
  Use a clean, minimalist design pattern similar to TeuxDeux</action>

</task>

<task type="auto">
  <name>Implement Task Storage Service</name>
  <files>src/services/storage.ts</files>
  <action>Create a localStorage-based data persistence service that:
  - Saves tasks with unique identifiers
  - Persists tasks across browser sessions
  - Supports CRUD operations for tasks
  - Handles data integrity checks
  - Manages task expiration and cleanup</action>
  <verify>npm test passes, data persists between page reloads, no data loss</verify>
  <done>Tasks can be saved to localStorage, retrieved from localStorage, and persist across sessions</done>
</task>

<task type="auto">
  <name>Add Basic Task Management Features</name>
  <files>src/components/TaskManager.tsx</files>
  <action>Implement core task management functionality:
  - Create tasks with title, date, and description
  - Edit existing task details
  - Delete tasks
  - Tasks display in appropriate day columns
  - Visual indicators for task status
  - Proper error handling for edge cases</action>
  <verify>npm test passes, all CRUD operations work correctly, errors handled gracefully</verify>
  <done>Tasks can be added, edited, and deleted, displayed in proper day columns</done>
</task>

<task type="auto">
  <name>Enable Drag and Drop Functionality</name>
  <files>src/components/TaskManager.tsx</files>
  <action>Implement HTML5 Drag and Drop API for task reorganization:
  - Make tasks draggable between days
  - Provide visual feedback during drag operations
  - Handle drop targets correctly
  - Maintain task data integrity after reorganization
  - Smooth, responsive dragging experience</action>
  <verify>npm test passes, drag and drop works smoothly, no data corruption</verify>
  <done>Tasks can be dragged between days, drop targets are clear, data remains consistent</done>
</task>

<task type="auto">
  <name>Add Horizontal Time Navigation</name>
  <files>src/components/CalendarView.tsx</files>
  <action>Implement horizontal navigation for:
  - Left/right scrolling to view past and future dates
  - Support for navigating through weeks and months
  - Smooth horizontal scrolling with momentum
  - Ability to scroll to view 1-14 days at a time
  - Visual indicators for current date range
  - Date range customization controls</action>
  <verify>npm test passes, horizontal scrolling works smoothly, date navigation is intuitive</verify>
  <done>Users can scroll left to see past todos and right to see future dates, date range customization works</done>
</task>

<task type="auto">
  <name>Add Task Completion Toggle</name>
  <files>src/components/TaskManager.tsx</files>
  <action>Implement functionality to mark tasks as complete/incomplete:
