+```
+Input Parsing:
+   ├─ Parse flags: --session, --interactive
+   └─ Detect mode: task-id present → Task mode | Otherwise → Session mode
+
+Phase 1: Mode Detection & Session Discovery
+   ├─ Detect operation mode (Task vs Session)
+   ├─ Discover/validate session (--session flag or auto-detect)
+   └─ Load session context (workflow-session.json, IMPL_PLAN.md, TODO_LIST.md)
+
+Phase 2: Interactive Requirement Clarification
+   └─ Decision (by mode):
+      ├─ Session mode → 3-4 questions (scope, modules, changes, dependencies)
+      └─ Task mode → 2 questions (update type, ripple effect)
+
+Phase 3: Impact Analysis & Planning
+   ├─ Analyze required changes
+   ├─ Generate modification plan
+   └─ User confirmation (Execute / Adjust / Cancel)
+
+Phase 4: Backup Creation
+   └─ Backup all affected files with manifest
+
+Phase 5: Apply Modifications
+   ├─ Update IMPL_PLAN.md (if needed)
+   ├─ Update TODO_LIST.md (if needed)
+   ├─ Update/Create/Delete task JSONs
+   └─ Update session metadata
+
+Phase 6: Verification & Summary
+   ├─ Validate consistency (JSON validity, task limits, acyclic dependencies)
+   └─ Generate change summary
