## Features

### Conversation History

Each session with a persona maintains full conversation history:
- All your questions are saved
- All responses are preserved
- Switch between personas to compare perspectives
- Clear conversation button to start fresh

### Quick Suggestions

Pre-written questions to help you get started:
- "What's the most important issue facing downtown?"
- "Should we allow food trucks in the plaza?"
- "How can we make the city more sustainable?"
- "What do you think about the affordable housing crisis?"

### Context Awareness

All responses consider:
- The downtown district environmental context
- Recent events and upcoming decisions
- The persona's values, background, and expertise
- Their communication style and typical concerns

## Tips for Effective Use

### 1. Start Broad, Then Go Specific

```
Good progression:
1. "What are your priorities for downtown?"
2. "How do you feel about new development?"
3. "What about the 500-unit condo proposal on 5th St?"
```

### 2. Compare Perspectives

Ask the same question to multiple personas:
1. Ask Sarah Chen (planner) about bike lanes
2. Switch to Marcus Thompson (business owner)
3. Ask the same question
4. See how their values shape different responses

### 3. Use Realistic Scenarios

```
Weak: "What do you think?"
Strong: "The city is considering a $50M bond for affordable
        housing. It would add 200 units but increase property
        taxes by $150/year. What's your position?"
```

### 4. Ask Follow-up Questions

```
Initial: "Should we add more bike lanes?"
Follow-up: "What about concerns from business owners?"
Follow-up: "How would you address parking issues?"
```

### 5. Explore Trade-offs

```
Good questions:
- "How would you balance economic growth with affordability?"
- "What's more important: parking or bike infrastructure?"
- "How do we develop without displacing residents?"
```

## Use Cases

### 5. Policy Analysis

**Evaluate proposed policies:**
- Get immediate feedback from different angles
- Identify unintended consequences
- Understand equity implications
- Find opportunities for compromise

## Technical Details

### Performance

- First query may take 3-5 seconds (model initialization)
- Subsequent queries: 2-4 seconds each
- Conversation history is stored in browser session
- No data is saved between sessions (privacy-preserving)

### Browser Compatibility

Tested and working on:
- Chrome 90+
- Firefox 88+
- Safari 14+
- Edge 90+

### Port Configuration

Default port: `8501`

To use a different port:
```bash
streamlit run web_app.py --server.port 8502
```

### Customization

The web app reads from:
- `data/personas/*.json` - Persona definitions
- `data/contexts/*.json` - Environmental contexts
- `.env` - API configuration

Any changes to these files will be reflected after refreshing the browser.

## Troubleshooting

### App won't start

**Check Python version:**
```bash
python --version  # Should be 3.11+
```

**Reinstall dependencies:**
```bash
pip install -r requirements.txt
```

### "No personas loaded" error

**Check persona files exist:**
```bash
ls data/personas/
```

Should show 6 JSON files. If not, verify git repository is complete.

### API errors

**Verify API key:**
```bash
cat .env | grep ANTHROPIC_API_KEY
```

Should show your API key. If missing, add it to `.env`.

### Slow responses

**Check model configuration:**

In `.env`, you're using:
```
LLM_MODEL=claude-3-haiku-20240307
```

This is the fastest model. For better quality (but slower), you could upgrade to Sonnet or Opus.

### Persona not responding

**Check browser console:**
- Right-click → Inspect → Console tab
- Look for error messages
- Common issue: API rate limits

**Refresh the page:**
- Clears session state
- Reinitializes connections

### Clear stuck session

**Browser refresh:** Press F5 or Ctrl+R

**Clear cache:**
```bash
streamlit cache clear
```

## Keyboard Shortcuts

While in the text input field:
- **Enter**: Send message
- **Shift+Enter**: New line (in the future, for multi-line input)
- **Escape**: Clear input field

## Privacy & Data

### What's Stored

**Not stored:**
- No conversation logs saved to disk
