+
+### Notification System
+
+**Three Verbosity Levels:**
+- `off` - No notifications (default)
+- `errors` - Show only failed tool calls
+- `all` - Show all tool calls and results
+
+**Notification Types:**
+- **Tool Call** - `🔧 MCP: list({ path: "projects", recursive: true })`
+- **Success** - `✅ MCP: list completed (142ms)`
+- **Error** - `❌ MCP: create_note failed - Parent folder does not exist`
+
+**Tool Icons:**
+- 📖 Read operations (`read_note`, `read_excalidraw`)
+- ✏️ Write operations (`create_note`, `update_note`, `update_frontmatter`, `update_sections`)
+- 🗑️ Delete operations (`delete_note`)
+- 📝 Rename operations (`rename_file`)
+- 🔍 Search operations (`search`, `search_waypoints`)
+- 📋 List operations (`list`)
+- 📊 Stat operations (`stat`, `exists`)
+- ℹ️ Info operations (`get_vault_info`)
+- 🗺️ Waypoint operations (`get_folder_waypoint`)
+- 📁 Folder operations (`is_folder_note`)
+- 🔗 Link operations (`validate_wikilinks`, `resolve_wikilink`, `backlinks`)
+
+### Rate Limiting
+
+- Queue-based notification display
+- Maximum 10 notifications per second
+- 100ms interval between notifications
+- Prevents UI freezing during bulk operations
+- Async processing doesn't block tool execution
+
+### History Tracking
+
+**Storage:**
+- Last 100 tool calls stored in memory
+- Automatic pruning when limit exceeded
+- Cleared on plugin reload
+
+**History Entry:**
+```typescript
+interface NotificationHistoryEntry {
+  timestamp: number;      // When the tool was called
+  toolName: string;       // Name of the tool
+  args: any;              // Tool parameters
+  success: boolean;       // Whether the call succeeded
+  duration?: number;      // Execution time in milliseconds
+  error?: string;         // Error message (if failed)
+}
+```
+
+**History Modal:**
+- Filter by tool name (text search)
+- Filter by type (all/success/error)
+- Shows count of filtered entries
+- Displays formatted entries with:
+  - Status icon (✅/❌)
+  - Tool name with color coding
+  - Timestamp and duration
+  - Parameters (JSON formatted)
+  - Error message (if failed)
+- Export to clipboard as JSON
+- Close button
+
+### Settings
+
+**Default Configuration:**
+```typescript
+{
+  notificationsEnabled: false,        // Disabled by default
+  notificationVerbosity: 'errors',    // Show errors only
+  showParameters: false,              // Hide parameters
+  notificationDuration: 3000,         // 3 seconds
+  logToConsole: false                 // No console logging
+}
+```
+
+**Configuration Options:**
+- **Enable notifications** - Master toggle
+- **Notification verbosity** - Control which notifications to show
+- **Show parameters** - Include tool parameters (truncated to 50 chars)
+- **Notification duration** - How long notifications stay visible (ms)
+- **Log to console** - Also log to browser console for debugging
+
+## Technical Details
+
+### Performance
+
+**When Disabled:**
+- Zero overhead
+- No notification manager created
+- No history tracking
+- No performance impact
+
+**When Enabled:**
+- Async notification queue
+- Non-blocking display
+- Minimal memory footprint (~10KB for 100 entries)
+- No impact on tool execution time
+
+### Privacy
+
+**Parameter Handling:**
+- Truncates long values (max 50 chars for display)
+- Optional parameter hiding
+- Doesn't show sensitive data (API keys, tokens)
+- File content truncated in parameters
+
+**Console Logging:**
+- Optional feature (disabled by default)
+- Logs to browser console for debugging
+- Always logs errors regardless of setting
+
+### Integration
+
+**Tool Call Flow:**
+```
+1. Client calls tool via MCP
+2. ToolRegistry.callTool() invoked
+3. Show "tool call" notification (if enabled)
+4. Execute tool
+5. Track execution time
+6. Show "success" or "error" notification
+7. Add entry to history
+8. Return result to client
+```
+
+**Notification Manager Lifecycle:**
+```
+1. Plugin loads
+2. Load settings
+3. Create notification manager (if enabled)
+4. Pass to server's tool registry
+5. Settings change → update notification manager
+6. Plugin unloads → cleanup
+```
+
+## Usage Examples
+
+### For Development
+
+**Verbose Mode:**
+```json
+{
+  "notificationsEnabled": true,
+  "notificationVerbosity": "all",
+  "showParameters": true,
+  "notificationDuration": 3000,
+  "logToConsole": true
+}
+```
+
+See every tool call with parameters and timing information.
+
+### For Production
+
+**Errors Only:**
+```json
+{
+  "notificationsEnabled": true,
+  "notificationVerbosity": "errors",
+  "showParameters": false,
+  "notificationDuration": 5000,
+  "logToConsole": false
+}
+```
+
+Only see failed operations with longer display time.
+
+### Disabled
+
+**No Notifications:**
+```json
+{
+  "notificationsEnabled": false,
+  "notificationVerbosity": "off",
+  "showParameters": false,
+  "notificationDuration": 3000,
+  "logToConsole": false
+}
+```
+
+Zero overhead, no visual feedback.
+
