# Enhanced Input Plugin - Bug Fix Report
**Date:** 2025-11-07
**Status:** RESOLVED ✅

---

## Issue Summary

The Enhanced Input Plugin was not rendering and falling back to default input display despite being enabled in config.

---

## Root Cause Analysis

### Bug #1: Plugin Discovery Failure (CRITICAL)

**Location:** `kollabor/plugins/discovery.py:164`

**The Problem:**
```python
# OLD CODE (BROKEN):
module_name = plugin_file.stem[:-7] if plugin_file.stem.endswith('_plugin') else plugin_file.stem
# This strips "_plugin" from filename:
# "enhanced_input_plugin.py" → "enhanced_input"

# Then line 210 tries to import:
module_path = f"plugins.{safe_name}"  # "plugins.enhanced_input" ❌
```

**Why It Failed:**
- File: `plugins/enhanced_input_plugin.py`
- Stripped name: `enhanced_input`
- Import attempt: `plugins.enhanced_input` ← Module doesn't exist!
- Actual module: `plugins.enhanced_input_plugin` ← This is the real name!

**The Fix:**
```python
# NEW CODE (WORKING):
module_name = plugin_file.stem  # e.g., "enhanced_input_plugin"
# Keep the full filename stem, don't strip anything

# Now import works:
module_path = f"plugins.{safe_name}"  # "plugins.enhanced_input_plugin" ✅
```

**Files Changed:**
- `kollabor/plugins/discovery.py:164` - Removed suffix stripping
- `kollabor/plugins/discovery.py:81` - Updated path construction

### Bug #2: Invalid Box Style Configuration

**Location:** `.kollabor-cli/config.json:158`

**The Problem:**
```json
"enhanced_input": {
  "enabled": true,
  "style": "rounded_double",  // ❌ This style doesn't exist!
```

**Error Message:**
```
ERROR: Failed executing hook render_fancy_input: 'Unknown box style: rounded_double'
```

**The Fix:**
```json
"enhanced_input": {
  "enabled": true,
  "style": "rounded",  // ✅ Valid style
```

## Test Results

### Before Fix:
```
Discovered plugins: ['enhanced_input', ...]
Loaded plugins: []  ← NO PLUGINS LOADED!
```

### After Fix:
```
Discovered plugins: ['enhanced_input_plugin', ...]
Loaded plugins: ['EnhancedInputPlugin', ...]  ← SUCCESS!

## Impact

### Affected Plugins
All 5 plugins were failing to load:
- ✅ `EnhancedInputPlugin` - NOW WORKING
- ✅ `HookMonitoringPlugin` - NOW WORKING
- ✅ `QueryEnhancerPlugin` - NOW WORKING
- ✅ `WorkflowEnforcementPlugin` - NOW WORKING (with constructor issues)
- ⚠️ `SystemCommandsPlugin` - Different loading mechanism

### System Impact
- **Before:** 0 plugins loaded, fallback input rendering
- **After:** 4 plugins loaded, enhanced input working with gradients

---

## Lessons Learned

1. **Module Naming:** Python module names must match actual file names
2. **Import Paths:** `plugins.enhanced_input` ≠ `plugins.enhanced_input_plugin`
3. **Configuration Validation:** Config values should be validated against available options
4. **Error Propagation:** Plugin load failures were silent - need better logging

---

## Recommendations

1. **Add Config Validation:** Validate box style names on config load
2. **Better Error Messages:** "Module not found" should suggest checking filename
3. **Plugin Registry Stats:** Show loaded vs discovered plugin count
4. **Config Schema:** JSON schema for validation
5. **Startup Diagnostics:** Display plugin load failures during startup
