- Auto-upload configuration via ~/.taptik/config.yaml
- Complete documentation including API reference, troubleshooting, and security guides

## Success Criteria Met
- All Claude Code configuration types successfully collected and processed
- Security sanitization effectively removes sensitive data
- Cloud metadata enables search and discovery in Taptik platform
- Generated .taptik packages compatible with cloud upload workflows
- Error handling provides clear guidance for troubleshooting
