+WHERE s.end_time IS NOT NULL
+GROUP BY DATE(s.start_time)
+ORDER BY date DESC;
+```
+
+## Data Retention
+
+- **Conversation Full Text**: Stored indefinitely for search and analysis
+- **Activity Details**: Kept for all operations to maintain complete audit trail
+- **Analytics Aggregations**: Computed on-demand from source data
+- **Cleanup**: Manual cleanup tools provided, no automatic data expiration
+
+## Performance Considerations
+
+- Database file size grows approximately 1-5MB per day of active development
+- Full-text search indexes require periodic optimization (`PRAGMA optimize`)
+- Analytics queries use covering indexes to avoid table scans
+- Large file content is not stored, only file paths and change metrics
+
+## Migration Strategy
+
+Schema migrations are handled through versioned SQL scripts in `/migrations/`:
+- Each migration has up/down scripts
+- Version tracking in `schema_versions` table
+- Automatic backup before migrations
+- Rollback capability for failed migrations

+
+## Environment Configuration
+
+Copy the example environment file:
+
+```bash
+cp .env.example .env
+```
+
+Configure these variables in `.env`:
+
+```bash
+# Database
+DATABASE_URL=sqlite:///./data/tracker.db
+
+# API Configuration  
+API_HOST=0.0.0.0
+API_PORT=8000
+DEBUG=true
+
+# Security (generate with: openssl rand -hex 32)
+SECRET_KEY=your-secret-key-here
+ACCESS_TOKEN_EXPIRE_MINUTES=30
+
+# Analytics
+ENABLE_ANALYTICS=true
+ANALYTICS_BATCH_SIZE=1000
+
+# Logging
+LOG_LEVEL=INFO
+LOG_FILE=tracker.log
+```
+
+## Database Setup
+
+### Initialize Database
+
+```bash
+# Create database and tables
+python -m app.database.init_db
+
+# Verify database creation
+sqlite3 data/tracker.db ".tables"
+```
+
+### Database Migrations
+
+```bash
+# Create a new migration
+python -m app.database.migrate create "add_new_field"
+
+# Apply migrations
+python -m app.database.migrate up
+
+# Rollback migration
+python -m app.database.migrate down
+```
+
+### Sample Data
+
+Load test data for development:
+
+```bash
+# Load sample projects and sessions
+python -m app.database.seed_data
+
+# Clear all data
+python -m app.database.clear_data
+```
+
+## Testing
+
+### Run Tests
+
+```bash
+# Run all tests
+pytest
+
+# Run with coverage
+pytest --cov=app --cov-report=html
+
+# Run specific test file
+pytest tests/test_api.py
+
+# Run tests matching pattern
+pytest -k "test_session"
+
+# Run tests with verbose output
+pytest -v
+```
+
+### Test Database
+
+Tests use a separate in-memory database:
+
+```python
+# tests/conftest.py
+@pytest.fixture
+async def test_db():
+    # Create in-memory SQLite database for testing
+    engine = create_async_engine("sqlite+aiosqlite:///:memory:")
+    # ... setup code
+```
+
+### Writing Tests
+
+```python
+# tests/test_api.py
+import pytest
+from httpx import AsyncClient
+from app.main import app
+
+@pytest.mark.asyncio
+async def test_create_session(test_db, test_client):
+    response = await test_client.post(
+        "/api/session/start",
+        json={
+            "session_type": "startup",
+            "working_directory": "/test/path"
+        }
+    )
+    assert response.status_code == 201
+    data = response.json()
+    assert data["session_id"] is not None
+```
+
+## Development Workflow
+
+### Code Style
+
+We use Black for formatting and isort for import sorting:
+
+```bash
+# Format code
+black app/ tests/
+
+# Sort imports  
+isort app/ tests/
+
+# Check formatting without changes
+black --check app/ tests/
+```
+
+### Linting
+
+```bash
+# Run flake8 linting
+flake8 app/ tests/
+
+# Type checking with mypy
+mypy app/
+```
+
+### Pre-commit Hooks
+
+Install pre-commit hooks to run checks automatically:
+
+```bash
+# Install hooks
+pre-commit install
+
+# Run hooks manually
+pre-commit run --all-files
+```
+
+### Git Workflow
+
+1. **Create feature branch:**
+   ```bash
+   git checkout -b feature/new-analytics-endpoint
+   ```
+
+2. **Make changes and test:**
+   ```bash
+   # Make your changes
+   pytest  # Run tests
+   black app/ tests/  # Format code
+   ```
+
+3. **Commit changes:**
+   ```bash
+   git add .
+   git commit -m "Add new analytics endpoint for productivity metrics"
+   ```
+
+4. **Push and create PR:**
+   ```bash
+   git push origin feature/new-analytics-endpoint
+   ```
+
+## API Development
+
+### Adding New Endpoints
+
+1. **Define Pydantic schemas** in `app/models/schemas.py`:
+   ```python
+   class NewFeatureRequest(BaseModel):
+       name: str
+       description: Optional[str] = None
+   ```
+
+2. **Create route handler** in appropriate module:
+   ```python
+   @router.post("/api/new-feature", response_model=NewFeatureResponse)
+   async def create_new_feature(
+       request: NewFeatureRequest,
+       db: AsyncSession = Depends(get_db)
+   ):
+       # Implementation
+   ```
+
+3. **Add tests** in `tests/test_api.py`:
+   ```python
+   async def test_create_new_feature(test_client):
+       # Test implementation
+   ```
+
+### Database Queries
+
+Use SQLAlchemy with async/await:
+
+```python
+from sqlalchemy.ext.asyncio import AsyncSession
+from sqlalchemy import select
+from app.models.project import Project
+
+async def get_projects(db: AsyncSession, limit: int = 10):
+    result = await db.execute(
+        select(Project).limit(limit)
+    )
+    return result.scalars().all()
+```
+
+## Frontend Development
+
+### Web Dashboard
+
+The dashboard uses vanilla HTML/CSS/JavaScript:
+
+```
+app/dashboard/
+├── static/
+│   ├── css/
+│   │   └── dashboard.css
+│   ├── js/
+│   │   ├── dashboard.js
+│   │   ├── charts.js
+│   │   └── api-client.js
+│   └── images/
+└── templates/
+    ├── base.html
+    ├── dashboard.html
+    └── projects.html
+```
+
+### Adding New Dashboard Pages
+
+1. **Create HTML template:**
+   ```html
+   <!-- app/dashboard/templates/new-page.html -->
+   {% extends "base.html" %}
+   {% block content %}
+   <!-- Page content -->
+   {% endblock %}
+   ```
+
+2. **Add route handler:**
+   ```python
+   @dashboard_router.get("/new-page")
+   async def new_page(request: Request):
+       return templates.TemplateResponse("new-page.html", {"request": request})
+   ```
+
+3. **Add JavaScript if needed:**
+   ```javascript
+   // app/dashboard/static/js/new-page.js
+   class NewPageController {
+       // Page logic
+   }
+   ```
+
+## Debugging
+
+### Logging
+
+Configure logging in `main.py`:
+
+```python
+import logging
+logging.basicConfig(
+    level=logging.INFO,
+    format="%(asctime)s - %(name)s - %(levelname)s - %(message)s",
+    handlers=[
+        logging.FileHandler("tracker.log"),
+        logging.StreamHandler()
+    ]
+)
+```
+
+### Database Debugging
+
+Enable SQL query logging:
+
+```python
+# In development.py
+engine = create_async_engine(
+    DATABASE_URL,
+    echo=True  # This logs all SQL queries
+)
+```
+
+### API Debugging
+
+Use FastAPI's automatic documentation:
+
+- **Swagger UI**: http://localhost:8000/docs
+- **ReDoc**: http://localhost:8000/redoc
+
+### Hook Debugging
+
+Test hooks manually:
+
+```bash
+# Test session start
+curl -X POST http://localhost:8000/api/session/start \
+  -H "Content-Type: application/json" \
+  -d '{"session_type":"startup","working_directory":"'$(pwd)'"}'
+
+# Check logs
+tail -f tracker.log
+```
+
+## Performance
+
+### Database Optimization
+
+```bash
+# Analyze query performance
+sqlite3 data/tracker.db "EXPLAIN QUERY PLAN SELECT ..."
+
+# Rebuild indexes
+sqlite3 data/tracker.db "REINDEX;"
+
+# Vacuum database
+sqlite3 data/tracker.db "VACUUM;"
+```
+
+### API Performance
+
+```bash
+# Profile API endpoints
+pip install line_profiler
+kernprof -l -v app/api/sessions.py
+```
+
+## Deployment
+
+### Production Setup
+
+1. **Environment variables:**
+   ```bash
+   DEBUG=false
+   API_HOST=127.0.0.1
+   ```
+
+2. **Database backup:**
+   ```bash
+   cp data/tracker.db data/tracker.db.backup
+   ```
+
+3. **Run with Gunicorn:**
+   ```bash
+   pip install gunicorn
+   gunicorn main:app -w 4 -k uvicorn.workers.UvicornWorker
+   ```
+
+### Docker Setup
+
+```dockerfile
+FROM python:3.11-slim
+
+WORKDIR /app
+COPY requirements.txt .
+RUN pip install -r requirements.txt
+
+COPY . .

+# Claude Code Hook Setup Guide
+
+This guide explains how to configure Claude Code hooks to automatically track your development sessions with the Project Tracker API.
+
+## Overview
+
+Claude Code hooks are shell commands that execute in response to specific events. We'll configure hooks to send HTTP requests to our tracking API whenever key development events occur.
+
+## Prerequisites
+
+1. **Claude Code Project Tracker** server running on `http://localhost:8000`
+2. **curl** or **httpie** available in your shell
+3. **jq** for JSON processing (recommended)
+
+## Hook Configuration Location
+
+Claude Code hooks are configured in your settings file:
+- **Linux/macOS**: `~/.config/claude-code/settings.json`
+- **Windows**: `%APPDATA%\claude-code\settings.json`
+
+## Complete Hook Configuration
+
+Add this hooks section to your Claude Code settings:
+
+```json
+{
+  "hooks": {
+    "SessionStart": [
+      {
+        "matcher": "startup",
+        "command": "curl -s -X POST http://localhost:8000/api/session/start -H 'Content-Type: application/json' -d '{\"session_type\":\"startup\",\"working_directory\":\"'\"$PWD\"'\",\"git_branch\":\"'$(git branch --show-current 2>/dev/null || echo \"unknown\")'\",\"git_repo\":\"'$(git config --get remote.origin.url 2>/dev/null || echo \"null\")'\",\"environment\":{\"pwd\":\"'\"$PWD\"'\",\"user\":\"'\"$USER\"'\",\"timestamp\":\"'$(date -Iseconds)'\"}}' > /dev/null 2>&1 &"
+      },
+      {
+        "matcher": "resume",

+
+## Simplified Hook Configuration
+
+For easier setup, you can use our provided configuration file:
+
+```bash
+# Copy the hook configuration to Claude Code settings
+cp config/claude-hooks.json ~/.config/claude-code/
+```
+
+## Hook Details
+
+### SessionStart Hooks
+
+Triggered when starting Claude Code or resuming a session:
+- **startup**: Fresh start of Claude Code
+- **resume**: Resuming after --resume flag  
+- **clear**: Starting after clearing history
+
+**Data Captured:**
+- Working directory
+- Git branch and repository
+- System environment info
+- Session type
+
+### UserPromptSubmit Hook
+
+Triggered when you submit a prompt to Claude:
+
+**Data Captured:**
+- Your input message
+- Timestamp
+- Session context
+
+### Notification Hook
+
+Triggered when Claude is waiting for input:
+
+**Data Captured:**
+- Wait start time
+- Context before waiting
+
+### PostToolUse Hooks
+
+Triggered after successful tool execution:
+
+**Tools Tracked:**
+- **Edit/Write**: File modifications
+- **Read**: File examinations  
+- **Bash**: Command executions
+- **Grep/Glob**: Search operations
+- **Task**: Subagent usage
+
+**Data Captured:**
+- Tool name and action
+- Target files
+- Success/failure status
+- Tool-specific metadata
+
+### Stop Hook
+
+Triggered when Claude finishes responding:
+
+**Data Captured:**
+- Response completion
+- End of waiting period
+- Session activity summary
+
+## Testing Hook Configuration
+
+1. **Start the tracker server:**
+   ```bash
+   python main.py
+   ```
+
+2. **Verify hooks are working:**
+   ```bash
+   # Check server logs for incoming requests
+   tail -f tracker.log
+   
+   # Test a simple operation in Claude Code
+   # You should see API calls in the logs
+   ```
+
+3. **Manual hook testing:**
+   ```bash
+   # Test session start hook
+   curl -X POST http://localhost:8000/api/session/start \
+     -H 'Content-Type: application/json' \
+     -d '{"session_type":"startup","working_directory":"'$(pwd)'"}'
+   ```
+
+## Environment Variables
+
+The hooks can use these Claude Code environment variables:
+
+- `$CLAUDE_USER_PROMPT` - User's input message
+- `$CLAUDE_TOOL_FILE_PATH` - File path for file operations
+- `$CLAUDE_BASH_COMMAND` - Bash command being executed
+- `$CLAUDE_GREP_PATTERN` - Search pattern for Grep
+- `$CLAUDE_GLOB_PATTERN` - File pattern for Glob
+- `$CLAUDE_TASK_TYPE` - Type of Task/subagent
+
+## Troubleshooting
+
+### Hooks Not Firing
+
+1. **Check Claude Code settings syntax:**
+   ```bash
+   # Validate JSON syntax
+   python -m json.tool ~/.config/claude-code/settings.json
+   ```
+
+2. **Verify tracker server is running:**
+   ```bash
+   curl http://localhost:8000/api/projects
+   ```
+
+3. **Check hook command syntax:**
+   ```bash
+   # Test commands manually in shell
+   echo "Testing hook command..."
+   ```
+
+### Missing Data
+
+1. **Session ID issues**: The static `session_id: 1` in examples needs dynamic generation
+2. **JSON escaping**: Special characters in prompts/paths may break JSON
+3. **Network issues**: Hooks may fail if server is unreachable
+
+### Performance Impact
+
+- Hooks run asynchronously (`&` at end of commands)
+- Failed hook calls don't interrupt Claude Code operation
+- Network timeouts are handled gracefully
+
+## Advanced Configuration
+
+### Dynamic Session IDs
+
+For production use, implement session ID management:
+
+```bash
+# Store session ID in temp file
+CLAUDE_SESSION_FILE="/tmp/claude-session-id"
+
+# In SessionStart hook:
+SESSION_ID=$(curl -s ... | jq -r '.session_id')
+echo $SESSION_ID > $CLAUDE_SESSION_FILE
+
+# In other hooks:
+SESSION_ID=$(cat $CLAUDE_SESSION_FILE 2>/dev/null || echo "1")
+```
+
+### Conditional Hook Execution
+
+Skip tracking for certain directories:
+
+```bash
+# Only track in specific directories
+if [[ "$PWD" =~ "/projects/" ]]; then
+  curl -X POST ...
+fi
+```
+
+### Error Handling
+
+Add error logging to hooks:
+
+```bash
+curl ... 2>> ~/claude-tracker-errors.log || echo "Hook failed: $(date)" >> ~/claude-tracker-errors.log
+```
+
+## Security Considerations
+
+- Hooks execute with your shell privileges
+- API calls are made to localhost only
+- No sensitive data is transmitted externally
+- Hook commands are logged in shell history
+
+## Next Steps
+
+After setting up hooks:
+
+1. Start using Claude Code normally
+2. Check the web dashboard at http://localhost:8000
+3. Review captured data and analytics
+4. Adjust hook configuration as needed
+
+For detailed API documentation, see [API Specification](api-spec.yaml).
