+<objective>
+Detect the current project state and automatically invoke the next logical GSD workflow step.
+No arguments needed — reads STATE.md, ROADMAP.md, and phase directories to determine what comes next.
+
+Designed for rapid multi-project workflows where remembering which phase/step you're on is overhead.
