-# Implementation Plan: Improve Error Display in Webview
-
-## Overview
-
-Currently, `cline.say("error", ...)` displays error text in red. We want to improve this to look more like the "Edit Unsuccessful" display with:
-
-1. A custom title that can be passed as metadata
-2. An expandable/collapsible UI pattern
-3. The error text shown when expanded
-
-## Current Implementation Analysis
-
-### 1. Error Display Flow
-
-- **Backend (Task.ts)**: `say("error", text)` method sends error messages
-- **Frontend (ChatRow.tsx)**: Renders error messages with red text styling
-- **Diff Error Pattern**: Already implements the expandable UI pattern we want to replicate
-
-### 2. Diff Error Implementation (lines 960-1048 in ChatRow.tsx)
-
-The diff_error display has:
-
-- Warning icon with yellow/orange color
-- Bold title ("Edit Unsuccessful")
-- Copy button
-- Expand/collapse chevron
-- Expandable content area showing the error details
-
-## Implementation Steps
-
-### Step 1: Extend the say method signature
-
-**File**: `src/core/task/Task.ts`
-
-The say method already accepts an `options` parameter with metadata support. We need to:
-
-- Document that error messages can include a `title` in metadata
-- No changes needed to the method signature itself
-
-### Step 2: Update ChatRow.tsx to handle enhanced error display
-
-**File**: `webview-ui/src/components/chat/ChatRow.tsx`
-
-Changes needed:
-
-1. Add state for error expansion (similar to `isDiffErrorExpanded`)
-2. Extract metadata from error messages
-3. Render errors with the expandable UI pattern
-4. Use custom title from metadata or default to "Error"
-
-### Step 3: Update translation files
-
-**Files**: All files in `webview-ui/src/i18n/locales/*/chat.json`
-
-Add new translation keys:
-
-- `error.defaultTitle`: Default title when no custom title is provided
-- Keep existing `error` key for backward compatibility
-
-### Step 4: Update existing error calls
-
-Search for all `say("error", ...)` calls and optionally add metadata with custom titles where appropriate.
-
-## Technical Details
-
-### Message Structure
-
-```typescript
-// When calling say with error and custom title:
-await this.say(
-	"error",
-	"Detailed error message here",
-	undefined, // images
-	false, // partial
-	undefined, // checkpoint
-	undefined, // progressStatus
-	{
-		metadata: {
-			title: "Custom Error Title",
-		},
-	},
-)
-```
-
-### Frontend Rendering Logic
-
-```typescript
-// In ChatRow.tsx, for case "error":
-// 1. Extract title from metadata or use default
-// 2. Render expandable UI similar to diff_error
-// 3. Show error text in expanded section
-```
-
-## Benefits
-
-1. **Consistency**: Error display matches the existing "Edit Unsuccessful" pattern
-2. **Clarity**: Custom titles provide immediate context about the error type
-3. **User Experience**: Collapsible errors reduce visual clutter
-4. **Flexibility**: Backward compatible - existing error calls continue to work
-
-## Testing Considerations
-
-1. Test with errors that have custom titles
-2. Test with errors without custom titles (should use default)
-3. Test expand/collapse functionality
-4. Test copy button functionality
-5. Verify all translations work correctly
-
-## Migration Strategy
-
-- The implementation is backward compatible
-- Existing `say("error", ...)` calls will continue to work
-- We can gradually update error calls to include custom titles where beneficial
