## 🔐 Security Considerations

### Protected Secrets
- Never commit `.env` files
- Use GitHub Secrets for credentials
- Base64 encode private keys
- Rotate keys periodically

### GitHub App Advantages
- Limited scope (this repository only)
- Better audit trail
- Automatic token expiration
- Fine-grained permissions

### Environment Isolation
- Production: HF Spaces environment variables
- Development: Local `.env` file (not committed)
- CI/CD: GitHub Actions secrets

- [ ] Webhook handling for real-time events
- [ ] Auto-fix implementation (create PRs)
- [ ] Code review suggestions
- [ ] Performance optimization

### Phase 3
- [ ] Multi-repo support
- [ ] Custom analysis rules
- [ ] Integration with more AI models
- [ ] Advanced analytics dashboard

### Phase 4
- [ ] Team collaboration features
- [ ] Scheduled reports
- [ ] Slack/Discord integration
- [ ] API rate limiting

---

## 📞 Support & Troubleshooting

### Common Issues

**Server won't start**
- Check GEMINI_API_KEY is set
- Verify GitHub auth configuration
- Check port 7860 isn't in use

**Chat API returns error**
- Verify GEMINI_API_KEY is valid
- Check API quota
- Review error logs

**GitHub integration fails**
- Verify GitHub App ID and installation ID
- Check private key is properly base64 encoded
- Ensure app is installed on repository

See TESTING.md for detailed troubleshooting.
