- User's Downloads folder
- User's Documents folder
- User's Desktop folder

Any attempt to write outside these directories will result in an error.

## Development

### Scripts

- `npm run build`: Compile TypeScript to JavaScript
- `npm start`: Run the compiled server
- `npm run dev`: Run in development mode with tsx
- `npm test`: Run tests

## Troubleshooting

### Common Issues

**Puppeteer fails to launch:**
- Ensure you have the required system dependencies
- On Linux: `sudo apt-get install -y gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget`

**Permission errors:**
- Ensure the output directory exists and is writable
- Check that the user has permissions to write to the target directory

**Module not found errors:**
- Run `npm install` to ensure all dependencies are installed
- Rebuild the project with `npm run build`
