## ⏳ Remaining Steps

### Step 1: Install Dependencies
**Status**: ⚠️ **BLOCKED - Requires npm**

```bash
cd ui/desktop
npm install
```

**What this does**:
- Installs `@monaco-editor/react@^4.6.0`
- Monaco Editor will be loaded from CDN at runtime
- No additional configuration needed

---

### Step 2: Integrate Monaco into RichChatInput
**Status**: 📋 **Ready to implement after npm install**

**File**: `ui/desktop/src/components/RichChatInput.tsx`

#### Changes Needed:

**A. Add imports (top of file, around line 7)**:
```typescript
// ADD THIS:
import { lazy, Suspense } from 'react';
import MonacoCodeInput from './MonacoCodeInput';

// Lazy load Monaco for better performance
const MonacoCodeInputLazy = lazy(() => import('./MonacoCodeInput').then(m => ({ default: m.MonacoCodeInput })));
```

**B. Replace SyntaxHighlighter in code mode rendering (around line 665-740)**:

Find this section:
```typescript
{/* Code content with syntax highlighting - constrained to container width */}
<div 
  className="block font-mono text-sm bg-[#1E1E1E]/30 rounded p-2 border border-gray-700/50 mt-1 w-full overflow-x-auto relative"
  style={{ 
    fontFamily: 'Monaco, Menlo, "Ubuntu Mono", Consolas, source-code-pro, monospace',
    maxWidth: '100%',
    boxSizing: 'border-box',
  }}
>
  {cursorInCode ? (
    // ... SyntaxHighlighter code ...
  ) : (
    // ... SyntaxHighlighter code ...
  )}
</div>
```

Replace with:
```typescript
{/* Monaco Editor for live code editing */}
<Suspense fallback={
  <div className="flex items-center justify-center h-32 bg-[#1E1E1E]/30 rounded border border-gray-700/50">
    <div className="animate-spin rounded-full h-8 w-8 border-t-2 border-b-2 border-blue-500" />
  </div>
}>
  <MonacoCodeInputLazy
    language={codeMode.language}
    value={codeContent}
    onChange={(newCode) => {
      // Update the full value with new code
      const beforeCode = value.slice(0, codeMode.startPos);
      const afterCode = value.slice(codeMode.startPos + codeContent.length);
      const newValue = beforeCode + newCode + afterCode;
      onChange(newValue, codeMode.startPos + newCode.length);
    }}
    onSend={() => {
      // Trigger send via parent's onKeyDown
      const syntheticEvent = new CustomEvent('submit', {
        detail: { value },
      }) as unknown as React.FormEvent;
      onKeyDown?.(syntheticEvent as any);
    }}
    onExit={() => {
      // Exit code mode
      setCodeMode(null);
    }}
    height="auto"
    theme="vs-dark"
    className="mt-1"
  />
</Suspense>
```

---

### Step 3: Add CSS Styling
**Status**: 📋 **Ready to implement**

**File**: `ui/desktop/src/styles/main.css`

Add at the end:
```css
/* Monaco Code Input Wrapper */
.monaco-code-input-wrapper {
  border-radius: 8px;
  border: 1px solid rgba(255, 255, 255, 0.1);
  overflow: hidden;
  background: #1E1E1E;
  margin-top: 8px;
}

/* Smooth transition when entering code mode */
.monaco-code-input-wrapper {
  animation: slideDown 0.2s ease-out;
}

@keyframes slideDown {
  from {
    opacity: 0;
    transform: translateY(-10px);
  }
  to {
    opacity: 1;
    transform: translateY(0);
  }
}

/* Loading spinner */
.monaco-loading {
  display: flex;
  align-items: center;
  justify-center;
  min-height: 100px;
}
```

### Step 4: Testing
**Status**: 📋 **After implementation**

#### Manual Testing Checklist:
- [ ] Start dev server: `npm run start-gui`
- [ ] Type `#python ` in chat input
- [ ] Verify Monaco loads (may take ~500ms first time)
- [ ] Type code and verify syntax highlighting
- [ ] Test autocomplete (type `def hel` and wait)
- [ ] Test Enter key (should insert newline)
- [ ] Test Cmd+Enter (should send message)
- [ ] Test Escape key (should exit code mode)
- [ ] Test with different languages (javascript, typescript, etc.)
- [ ] Verify height adjusts correctly
- [ ] Check performance with large code blocks

#### Test Cases:
1. **Basic activation**: `#python ` → Monaco appears
2. **Syntax highlighting**: Type code → Colors appear
3. **Autocomplete**: Type partial word → Suggestions appear
4. **Multi-line**: Press Enter → New line added
5. **Send**: Press Cmd+Enter → Message sent
6. **Exit**: Press Escape → Back to normal mode
7. **Language switching**: Try #javascript, #typescript, etc.

git add ui/desktop/package.json
git add ui/desktop/src/components/MonacoCodeInput.tsx

## 💡 Tips for Integration

### If Monaco doesn't load:
- Check browser console for errors
- Verify network tab shows CDN requests
- Try clearing browser cache

### If autocomplete doesn't work:
- Wait 1-2 seconds after typing
- Ensure language is supported
- Check Monaco loaded successfully

### If height is wrong:
- Check `calculatedHeight` in MonacoCodeInput
- Verify min/max constraints
- Test with different code lengths

### If keyboard shortcuts don't work:
- Verify `onSend` and `onExit` props are passed
- Check `addCommand` in `handleEditorDidMount`
- Test in browser dev tools
