 ## Core Rules
 **Complete entire workflow autonomously without user interruption, using TodoWrite for comprehensive progress tracking.**
 **Execute all discovered pending tasks until workflow completion or blocking dependency.**
-**Auto-complete session when all tasks finished: Call `/workflow:session:complete` upon workflow completion.**
+**User-choice completion: When all tasks finished, ask user to choose review or complete.**
 **ONE AGENT = ONE TASK JSON: Each agent instance executes exactly one task JSON file - never batch multiple tasks into single agent execution.**
