# Tool Status Indicators

## Problem

The ExploringCard showed tool calls but no visual feedback about their status:
- ❌ No indication which tools are still running
- ❌ No indication which tools succeeded/failed
- ❌ User couldn't tell if the system was stuck or working

## Solution

Added visual status indicators matching the internal `status` field:

### Status Types

1. **`calling`** - Tool is executing
   - Icon: ⏳ (spinning hourglass animation)
   - Shows: "Running command..."

2. **`success`** - Tool completed successfully
   - Icon: ✓ (green checkmark)
   - Shows: "Ran: python3..."

3. **`error`** - Tool failed
   - Icon: ✗ (red X)
   - Shows: "Error: ..."

## Implementation

### Component Changes

```typescript:255-277:ui/components/Chat/ExploringCard.tsx
{toolCalls.map((toolCall, index) => {
  const displayText = getToolCallDisplayText(toolCall);
  
  // Determine status indicator
  let statusIndicator = null;
  if (toolCall.status === 'calling') {
    // Loading spinner for in-progress tools
    statusIndicator = <span className="exploring-tool-spinner">⏳</span>;
  } else if (toolCall.status === 'success') {
    // Success checkmark
    statusIndicator = <span className="exploring-tool-success">✓</span>;
  } else if (toolCall.status === 'error') {
    // Error X
    statusIndicator = <span className="exploring-tool-error">✗</span>;
  }
  
  return (
    <div key={toolCall.id || index} className="exploring-tool-item">
      <span className="exploring-tool-arrow">→</span>
      <span className="exploring-tool-name">{displayText}</span>
      {statusIndicator}
    </div>
  );
})}
```

### CSS Styling

```css:59-96:ui/components/Chat/ExploringCard.css
.exploring-tool-name {
  color: var(--text-secondary);
  flex: 1; /* Take remaining space */
}

/* Status indicators */
.exploring-tool-spinner {
  margin-left: 8px;
  font-size: 14px;
  animation: spin 1s linear infinite;
}

@keyframes spin {
  from { transform: rotate(0deg); }
  to { transform: rotate(360deg); }
}

.exploring-tool-success {
  margin-left: 8px;
  color: #10b981; /* Green */
  font-size: 14px;
  font-weight: bold;
}

.exploring-tool-error {
  margin-left: 8px;
  color: #ef4444; /* Red */
  font-size: 14px;
  font-weight: bold;
}
```

## Visual Examples

### Before
```
Exploring
  → Ran: python3 -c <<'PY' import sys...
  → Ran: set -e curl -I -L --max-time 20 https://...
  → Ran: set -e curl -L --max-time 30 -s https://...
  → Searched for "$//>"
  → Got info from www.ventureguides.com
```

No indication of status - just shows text.

### After
```
Exploring
  → Running python3... ⏳
  → Fetching web content ⏳
  → Got info from ventureguides.com ✓
  → Searched for "$//>" ✓
  → Read file ✓
```

Clear visual feedback:
- ⏳ = Still running (animated)
- ✓ = Completed successfully (green)
- ✗ = Failed (red, if error)

## Why Not Show Results?

### Considered: Show result preview in card
```
→ Ran: ls -la ~/Documents ✓
  Found 42 files (3.2 KB)
```

**Rejected because:**
- ❌ Results can be MASSIVE (100K+ characters)
- ❌ Clutters the UI
- ❌ Adds cognitive load
- ❌ User sees results in assistant's text response anyway

### Current Approach: Just show status
```
→ Listed files ✓
```

**Benefits:**
- ✅ Clean, minimal UI
- ✅ Clear progress indication
- ✅ Results appear in assistant's natural response below
- ✅ Matches Paprwork V1 UX

## Status Flow

```
1. Tool call initiated
   → "Running command..." ⏳

2. Tool executing (10-30 seconds)
   → Still showing ⏳ (animated)

3. Tool completes
   → "Ran: command" ✓

4. Assistant uses result
   → "I found 42 files in Documents..."
```

## Alternative Considered: Collapsible Results

Could add optional "Show result" expansion:

```
→ Listed files ✓ [▼ Show details]
  
  When expanded:
  ────────────────────
  total 42
  -rw-r--r--  1 user  staff  1234 Feb 11 10:30 file1.txt
  -rw-r--r--  1 user  staff  5678 Feb 11 10:31 file2.txt
  ...
  ────────────────────
```

**Decision**: Skip for now. Can add later if users request it.

## Performance Impact

**Minimal:**
- No network requests
- No heavy rendering
- Just CSS animations for spinner
- Status already tracked in state

**Estimated overhead:**
- ~5ms per tool call to render icon
- ~0.1KB per icon in bundle

## Testing

Test the following scenarios:

1. **Single tool call**
   - Shows spinner → Shows checkmark
   
2. **Multiple parallel tool calls**
   - All show spinners → Each completes independently
   
3. **Tool error**
   - Shows spinner → Shows red X
   
4. **Long-running tool (60s+)**
   - Spinner keeps animating → Eventually completes

5. **Card collapse/expand**
   - Status indicators persist correctly

## Summary

✅ **Added**: Visual status indicators (⏳, ✓, ✗)  
✅ **Improved**: User feedback during long operations  
✅ **Maintained**: Clean, minimal UI  
✅ **Matches**: Paprwork V1 UX patterns

Users can now see at a glance which tools are running, which completed, and which failed.
