+# Documentation Tab Fix - Complete Resolution
+
+## Issue Resolved ✅
+
+**Problem**: Documentation tab content would appear briefly but disappear after 1-2 seconds in the Visual Workflow Builder.
+
+**Root Cause**: React state management conflict in PropertiesPanel component where tab state was being reset on every node parameter change.
+
+## Solution Applied
+
+### 1. Fixed PropertiesPanel State Management
+
+**Before (Problematic)**:
+```typescript
+useEffect(() => {
+  if (node) {
+    // ... parameter logic ...
+    setActiveTab(0); // ❌ Reset tab on every node change
+  }
+}, [node]); // Too broad dependency
+```
+
+**After (Fixed)**:
+```typescript
+useEffect(() => {
+  if (node) {
+    // ... parameter logic only ...
+  }
+}, [node]);
+
+// Separate effect for tab reset
+useEffect(() => {
+  setActiveTab(0);
+}, [node?.id]); // ✅ Only reset when node ID changes
+```
+
+### 2. Optimized DocumentationTab Dependencies
+
+```typescript
+// Improved dependency management
+useEffect(() => {
+  if (nodeType) {
+    loadDocumentation();
+  }
+}, [nodeType]); // Removed unnecessary selectedNodeId
+
+useEffect(() => {
+  if (nodeType && currentConfiguration) {
+    loadContextualHelp();
+  }
+}, [nodeType, JSON.stringify(currentConfiguration)]); // Stable comparison
+```
+
+### 3. Fixed TypeScript Compilation Error
+
+**Issue**: `selectedNodeId` parameter was declared but not used after optimization.
+
+**Fix**: Renamed parameter to `_selectedNodeId` to indicate intentional non-use:
+```typescript
+const DocumentationTab: React.FC<DocumentationTabProps> = ({
+  selectedNodeId: _selectedNodeId, // Renamed to indicate it's not used
+  nodeType,
+  currentConfiguration,
+  onToolSelect
+}) => {
+```
+
+## Files Modified
+
+1. `visual_workflow_builder/frontend/src/components/PropertiesPanel/index.tsx`
+2. `visual_workflow_builder/frontend/src/components/DocumentationTab/index.tsx`
+
+## Tests Created
+
+- `test_documentation_tab_fix.py`: Automated verification script
+- `fix_typescript_compilation.sh`: TypeScript compilation verification
+
+## Result
+
+✅ Documentation tab now remains visible and functional  
+✅ Content persists during user interactions  
+✅ Tab only resets when switching between different nodes  
+✅ All documentation features accessible  
+✅ TypeScript compilation errors resolved  
+
+**Status: RESOLVED** - Users can now access tool documentation without interruption and the code compiles without errors.
