Task: React Dashboard UI for Agent Monitoring

Description

Create a modern React-based web interface for monitoring agent status, task queues, and development progress in real-time. This dashboard will connect to the local Express server and provide interactive controls for managing development workflows.

Functional Requirements

• Real-time Monitoring: Live agent status, task queues, and progress tracking
• Interactive Controls: Pause, resume, reorder, and detail views for tasks
• Performance Metrics: Historical trends, execution times, and success rates
• Multi-Stream Visualization: Parallel work stream coordination and dependencies
• Responsive Design: Works on desktop, tablet, and mobile devices

Technical Implementation

Files to Create:

• web/src/App.js - Main React application component
• web/src/components/AgentMonitor.js - Agent status monitoring interface
• web/src/components/TaskQueue.js - Task queue visualization and controls
• web/src/components/PerformanceMetrics.js - Charts and metrics dashboard
• web/src/components/StreamCoordination.js - Multi-stream workflow visualization
• web/src/hooks/useWebSocket.js - WebSocket connection management
• web/src/hooks/useAgentData.js - Agent data state management
• web/public/index.html - Dashboard HTML template and assets

Modern React Architecture:

• React 18: Latest React features with concurrent rendering
• WebSocket Integration: Real-time data updates via custom hooks
• State Management: Context API + useReducer for complex state
• UI Framework: Tailwind CSS for styling and responsive design
• Charts: Chart.js or Recharts for performance visualization
• Icons: React Icons for consistent iconography

Acceptance Criteria

Core Dashboard Features:

• Loads in <3 seconds with responsive design
• Real-time updates via WebSocket with <500ms latency
• Displays all active agents with current status and progress
• Shows task queue with priority, dependencies, and estimated time
• Provides interactive controls for task management
• Historical performance metrics with charts and trends

Agent Monitoring Interface:

• Real-time agent status (idle, running, completed, error)
• Current task details and progress percentage
• Agent resource usage (memory, CPU, execution time)
• Agent logs and output streaming
• Color-coded status indicators and health monitoring
• Agent restart and configuration controls

Task Queue Management:

• Visual task queue with drag-and-drop reordering
• Task filtering by stream, status, and priority
• Detailed task view with requirements and progress
• Dependency visualization showing task relationships
• Pause/resume controls for individual tasks
• Task cancellation and retry capabilities

Performance Metrics Dashboard:

• Real-time performance charts (execution time, success rate)
• Historical trends over time (daily, weekly, monthly)
• Agent efficiency comparisons and benchmarks
• Project progress tracking with milestone indicators
• Resource utilization monitoring and alerts
• Export capabilities for performance reports

Multi-Stream Coordination:

• Visual representation of parallel work streams
• Dependency mapping between tasks and streams
• Stream progress tracking and completion estimates
• Conflict detection and resolution suggestions
• Team coordination features for shared projects

Responsive Design:

• Desktop (1920x1080+): Full dashboard with all features
• Tablet (768x1024): Responsive layout with touch controls
• Mobile (375x667): Essential monitoring with simplified interface
• Dark/light mode toggle for user preference
• Accessibility compliance (WCAG 2.1 AA)

User Experience Requirements

Navigation and Layout:

• Intuitive navigation with clear information hierarchy
• Customizable dashboard layout with draggable panels
• Quick access toolbar for common actions
• Search functionality for tasks, agents, and logs
• Keyboard shortcuts for power users

Real-time Feedback:

• Visual progress indicators for long-running tasks
• Toast notifications for important events
• Audio alerts for critical issues (optional)
• Status changes with smooth animations
• Connection status indicator for WebSocket

Data Visualization:

• Clear, readable charts with proper scaling
• Color-blind friendly color palette
• Tooltips and hover states for detailed information
• Zoom and pan capabilities for historical data
• Export options for charts and data

Dependencies

• Internal: Task 11 (Local server with WebSocket support)
• External: React 18, WebSocket API, Chart.js/Recharts, Tailwind CSS
• Integration: WebSocket server for real-time data streaming

WebSocket Data Flow:

// Real-time data structure from server
{
  type: 'agent_status_update',
  data: {
    agentId: 'security-agent-001',
    status: 'running',
    progress: 45,
    currentTask: 'Scanning authentication modules',
    estimatedTime: '2 minutes remaining'
  }
}

Performance Optimization:

• React.memo for expensive components
• Virtualization for large task lists
• Debounced search and filtering
• Lazy loading for historical data
• WebSocket message batching for high-frequency updates

Risks

• High: Complex real-time UI might have performance issues
• Medium: WebSocket connection reliability could affect user experience
• Medium: Browser compatibility issues with modern React features

Mitigation Strategies

• Comprehensive performance testing and optimization
• Robust WebSocket reconnection and fallback strategies
• Progressive enhancement for older browsers
• Extensive cross-browser and device testing
