+
+AI Workspace Console uses the shared Platform `ai-workspace-assistant` service. Tasker does not connect to AI Workspace Hub directly. The Tasker backend containers must be attached to the same Docker network as Platform/Engine through `NODEDC_ENGINE_DOCKER_NETWORK`; on NAS this is currently `nodedc-demo_default`, while local development uses `nodedc-platform_default`.
+
+Use the internal service URL on that shared network:
+
+```env
+PLANE_NODEDC_AI_WORKSPACE_ASSISTANT_URL=http://ai-workspace-assistant:18082
+```
+
+The Assistant generates Codex worker installers with the public Hub endpoint `wss://ai-hub.nodedc.ru/api/ai-workspace/hub`. Do not point Tasker directly at the Hub and do not expose Assistant as a public Nginx/DSM route.
 
 Production secrets remain in NAS env files or a secret store. They must not be committed.
