 ### 3. Task Routing
 
-Route tasks to the appropriate domain:
+**Use `component-registry.json` for routing decisions:**
+
+1. User request received
+2. Scan registry triggers for keyword matches
+3. Match found → invoke corresponding skill/command/agent
+4. No match → use domain routing below or ask for clarification

+**Domain routing (when registry doesn't match):**
 
 | Domain | Route To |
