   • Comprehensive relationships and computed properties
   • SQLite for local storage

3. API Endpoints (app/api/)

   • Sessions: Start/end development sessions
   • Conversations: Track dialogue with Claude
   • Activities: Record tool usage and file operations
   • Waiting: Monitor think times and engagement
   • Git: Track repository operations
   • Projects: Manage and query project data
   • Analytics: Advanced productivity insights

4. Web Dashboard (app/dashboard/)

   • Modern Bootstrap-based interface
   • Real-time charts and metrics
   • Project overview and timeline views
   • Conversation search functionality
   • Analytics and insights visualization

5. Hook Integration (config/claude-hooks.json)

   • Complete hook configuration for Claude Code
   • Automatic session tracking
   • Real-time data capture
   • Dynamic session ID management

🧪 Testing Infrastructure

• Comprehensive test suite with pytest
• Database fixtures for realistic test scenarios
• API integration tests covering all endpoints
• Hook simulation tests for validation
• Sample data generators for development

📚 Documentation

• Complete API specification (OpenAPI/Swagger)
• Database schema documentation with ERD
• Hook setup guide with examples
• Development guide for contributors
• Architecture overview in README

Key Features

📊 Analytics & Insights

• Productivity Metrics: Engagement scores, session analytics, think time analysis
• Development Patterns: Working hours, tool usage, problem-solving approaches
• Learning Insights: Topic frequency, skill development, complexity progression
• Git Intelligence: Commit patterns, change analysis, repository health

💻 Real-time Tracking

• Session Management: Automatic start/stop with context capture
• Conversation Logging: Full dialogue history with tool correlation
• Activity Monitoring: Every tool use, file operation, and command execution
• Engagement Analysis: Think times, flow states, productivity scoring

🔍 Advanced Search

• Semantic Conversation Search: Find discussions by meaning, not just keywords
• Project Filtering: Focus on specific codebases
• Timeline Views: Chronological development history
• Context Preservation: Maintain conversation threads and outcomes

📈 Visual Dashboard

• Interactive Charts: Productivity trends, tool usage, engagement patterns
• Project Overview: Statistics, language analysis, activity heatmaps
• Real-time Updates: Auto-refresh every 5 minutes
• Responsive Design: Works on desktop and mobile

Data Model

Core Entities

1. Projects - Development projects with metadata
2. Sessions - Individual development sessions
3. Conversations - User-Claude dialogue exchanges
4. Activities - Tool usage and file operations
5. WaitingPeriods - Think time and engagement tracking
6. GitOperations - Version control activity

Key Relationships

• Projects contain multiple Sessions
• Sessions have Conversations, Activities, WaitingPeriods, and GitOperations
• Activities can be linked to specific Conversations
• Comprehensive foreign key relationships maintain data integrity
