+<objective>
+Analyze freeform natural language input and dispatch to the most appropriate GSD command.
+
+Acts as a smart dispatcher — never does the work itself. Matches intent to the best GSD command using routing rules, confirms the match, then hands off.
+
+Use when you know what you want but don't know which `/gsd:*` command to run.
