### 💻 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

## Getting Started

### 1. Installation

```bash
# Install dependencies
pip install -r requirements.txt
pip install -r requirements-dev.txt

# Initialize database
python -m app.database.init_db

# Start server
python main.py
```

### 2. Hook Setup

```bash
# Copy hook configuration to Claude Code
cp config/claude-hooks.json ~/.config/claude-code/settings.json
```

### 3. Access Dashboard

- **Web Interface**: http://localhost:8000
- **API Documentation**: http://localhost:8000/docs
- **Health Check**: http://localhost:8000/health
