## Session Persistence

Quiz sessions are automatically saved to `~/.claude-quiz/`:

```
~/.claude-quiz/
  sessions/
    2026-01-12_143052.json   # Individual session data
    2026-01-12_150623.json
  stats.json                  # Aggregate statistics
```

### Session Data Includes:
- Profile and topics selected
- Questions answered (correct/incorrect/skipped)
- Time taken
- Category breakdown
- Wrong questions with correct answers

## Dynamic Question Generation

When the `--dynamic` flag is enabled and the Claude CLI is installed, the quiz can generate additional questions on-the-fly using `claude -p`:

```bash
node src/index.js -d
```

This requires:
- Claude CLI installed (`npm install -g @anthropic-ai/claude-code`)
- Active API key configured

Dynamic questions supplement the static pool when:
- Static pool is exhausted for selected topics
- User requests fresh questions
- Variety is needed for repeated quizzes

## Contributing Questions

We welcome question contributions! See [`templates/question-template.yaml`](./templates/question-template.yaml) for the format.

### Quality Guidelines

**Good questions test:**
- Practical application ("When should you...")
- Decision-making ("Which approach is best for...")
- Understanding ("Why does Claude...")
- Troubleshooting ("What would you do if...")

**Avoid:**
- Trivia ("What is the exact command syntax...")
- Pure memorization ("List all keyboard shortcuts...")
- Version-specific details that may change

### Submitting Questions

1. Fork the repository
2. Add questions to the appropriate `questions/XX-category.yaml` file
3. Follow the template format exactly
4. Ensure `doc_reference` points to valid sections
5. Submit a PR with description of added questions

## Troubleshooting

### "No questions available"

- Check that selected topics have questions in `questions/` directory
- Verify YAML files are valid (use a YAML validator)
- Try selecting different topics or "All topics"

### "Cannot find module 'yaml'"

```bash
cd quiz
npm install
```

### Quiz hangs on input

- Ensure you're running in an interactive terminal
- Try pressing Enter if stuck
- Use Ctrl+C to exit and restart
