• omd-dsh does not reinvent the wheel, it is a very thin layer of "wiring + organization": most of the core capabilities point to the DSH native mechanism, and this plug-in is only responsible for determining "which native capabilities are used in each mode and which model is used."
• omd featurepointed DSH native capabilities
• tier subagent delegationDSH native subagent (omd_task just exposes per-request model/persona selection)
• Read-only/no shell boundaryDSH native preset tool combination (not self-developed sandbox)
