 ## Task Decomposition Standards
 
+### Dynamic Task Planning Rules
+**Module Grouping**: Max 3 modules per task, max 30 files per task
+**Task Count**: Calculate based on `total_modules ÷ 3 (rounded up) + base_tasks`
+**File Limits**: Split tasks when file count exceeds 30 in any module group
+**Base Tasks**: System overview (1) + Architecture (1) + API consolidation (1)
+**Module Tasks**: Group related modules by dependency depth and functional similarity
