zxdl run --exclusive ./fan_control.zxdl Notice no sudo is required for hardware access—the XRT daemon handles privilege separation internally. One of the most praised features of the ZXDL Script Exclusive is its capability-based security . Traditional scripts run with the user's full permissions (confused deputy problem). ZXDL scripts, however, must declare a "capability manifest" at the top of the file. Example Capability Manifest @capabilities read: [ "/var/log/syslog", "/proc/stat" ] write: [ "/tmp/zxdl_cache/" ] network: [ "outbound:443" ] hardware: [ "thermal_zone0" ]
