# Clarification Quiz Enhancement - Implementation Summary

## Completed Backend Improvements ✅

### 1. Settings Configuration (`includes/class-settings.php`)

**Added three new settings:**

1. **Enable Clarification Quiz** (Checkbox)
   - Default: `true`
   - Allows users to completely enable/disable the quiz

2. **Confidence Threshold** (Select dropdown)
   - Options: 0.5 (Very Sensitive), 0.6 (Sensitive - Recommended), 0.7 (Balanced), 0.8 (Strict - Current), 0.9 (Very Strict)
   - Default: `0.6` (lowered from hardcoded 0.8)
   - Lower threshold = quiz appears more frequently

3. **Required Context Categories** (Multi-select)
   - 7 categories: Target Outcome, Target Audience, Tone, Content Depth, Expertise Level, Content Type, POV
   - Default: All categories selected
   - Users can deselect categories they don't need

**Files Modified:**
- `class-settings.php:233` - Sanitization for enable checkbox
- `class-settings.php:246-256` - Sanitization for threshold and categories
- `class-settings.php:280-291` - Extract settings from database
- `class-settings.php:537-633` - Settings UI HTML

---

### 2. Enhanced System Prompt (`includes/class-gutenberg-sidebar.php`)

**Updated the clarity check system prompt to:**

- **Evaluate 7 context categories** instead of 3 (topic, audience, scope)
- **Use configurable threshold** from settings (no longer hardcoded 0.8)
- **Generate only predefined options** - explicitly forbids `open_text` questions
- **Include category labels** in questions for better UX
- **Calculate confidence** by subtracting 15% per missing category

**New Categories:**
1. `target_outcome` - Education/Marketing/Sales/Entertainment/Brand Awareness
2. `target_audience` - Demographics, role, knowledge level
3. `tone` - Formal/Casual/Technical/Friendly/Professional/Conversational
4. `content_depth` - Quick Overview/Standard Guide/Detailed Analysis/Comprehensive
5. `expertise_level` - Beginner/Intermediate/Advanced/Expert
6. `content_type` - Tutorial/Opinion/Comparison/Listicle/Case Study/News Analysis
7. `pov` - First Person/Third Person/Expert Voice/Neutral

**Files Modified:**
- `class-gutenberg-sidebar.php:1186-1213` - Settings integration in `handle_check_clarity()`
- `class-gutenberg-sidebar.php:1224-1268` - New system prompt
- `class-gutenberg-sidebar.php:1590-1673` - Same updates in private `check_clarity_before_generation()`

---

### 3. Fallback Helper Method

**Created `get_default_clarification_questions()` method:**

- **Provides 7 predefined question templates** with curated options
- **Used when AI fails** (API errors, JSON parse errors)
- **Respects user's category selection** from settings
- **No more skipping the quiz** on errors - always shows fallback questions

**Question Templates Include:**
- Target outcome: 5 options (Education, Marketing, Sales, Entertainment, Brand Awareness)
- Target audience: 5 options (General Public, Professionals, Customers, Users, Peers)
- Tone: 5 options (Professional, Friendly, Technical, Casual, Formal)
- Content depth: 4 options (Quick Overview, Standard Guide, Detailed Analysis, Comprehensive)
- Expertise level: 4 options (Beginner, Intermediate, Advanced, Expert)
- Content type: 6 options (Tutorial, Opinion, Comparison, Listicle, Case Study, News Analysis)
- POV: 4 options (Third Person, First Person, Expert Voice, Neutral)

**Files Modified:**
- `class-gutenberg-sidebar.php:1687-1808` - New helper method

---

### 4. Improved Error Handling

**Updated both clarity check methods to use fallback:**

**Before:**
```php
if ( is_wp_error( $response ) ) {
    return array( 'is_clear' => true, 'confidence' => 1.0, 'questions' => array() );
}
```

**After:**
```php
if ( is_wp_error( $response ) ) {
    error_log( 'WP Agentic Writer: Clarity check API error - ' . $response->get_error_message() );
    return $this->get_default_clarification_questions( $topic );
}
```

**Benefits:**
- Quiz still appears even when AI fails
- Logs errors for debugging
- Better user experience (doesn't silently skip context gathering)

**Files Modified:**
- `class-gutenberg-sidebar.php:1283-1311` - Error handling in `handle_check_clarity()`
- `class-gutenberg-sidebar.php:1677-1693` - Error handling in `check_clarity_before_generation()`

---

### 5. Clarification Answers Integration

**Added clarification context to plan generation:**

- **Extracts answers from request parameters**
- **Formats answers by category with labels**
- **Adds context section to AI prompt** before generating outline
- **Respects skipped answers** (excludes them from context)

**Context Format in Prompt:**
```
=== CONTEXT FROM CLARIFICATION QUIZ ===
- Primary Goal: Education - Teach something new
- Target Audience: General public / Beginners
- Tone of Voice: Friendly & Conversational
- Content Depth: Standard guide (800-1500 words)
- Expertise Level: Beginner - No prior knowledge
- Content Type: Tutorial / How-to guide
- Point of View: Third person (objective, "it", "they")
=== END CONTEXT ===
```

**Files Modified:**
- `class-gutenberg-sidebar.php:344-365` - Extract clarification answers in `handle_generate_plan()`
- `class-gutenberg-sidebar.php:470` - Added parameter to `stream_generate_plan()`
- `class-gutenberg-sidebar.php:496-530` - Build and format clarification context
- `class-gutenberg-sidebar.php:576` - Inject context into AI prompt

### Problem Solved: Lack of Context

**Categories Added:**
- ✅ Target outcome (education/marketing/sales/etc)
- ✅ Tone of voice (formal/casual/technical)
- ✅ Content depth (overview/guide/analysis)
- ✅ Expertise level (beginner/intermediate/advanced)
- ✅ Content type (tutorial/opinion/how-to)

## Pending Work (Optional)

### Frontend Enhancements (`assets/js/sidebar.js`)

These are **optional improvements** to the user interface:

1. **Add category labels** to question cards
   - Show emoji icons for each category (🎯 Goal, 👥 Audience, etc.)
   - Display category badges above questions

2. **Enhanced progress display**
   - Show which categories are already clear
   - Display "Already know: Goal, Audience, Tone"
   - Better visual feedback on quiz progress

3. **Skip button** for each question
   - Allow marking questions as "not applicable"
   - Prevents users from getting stuck on irrelevant questions

**Note:** The current frontend will work without these changes. The quiz will just look the same as before, but with better questions and more frequent appearance.

4. **Threshold Test:**
   - Set threshold to 0.5 (Very Sensitive)
   - Enter "SEO tips"
   - Verify quiz appears
   - Set threshold to 0.9 (Very Strict)
   - Enter same topic
   - Verify quiz doesn't appear

5. **Category Filter Test:**
   - Uncheck some categories in settings
   - Enter vague topic
   - Verify quiz only asks for checked categories

6. **Settings Disable Test:**
   - Uncheck "Enable Clarification Quiz"
   - Enter vague topic
   - Verify quiz never appears

7. **API Failure Test:**
   - Use invalid API key
   - Enter vague topic
   - Verify fallback questions appear (not error or skip)

8. **Plan Integration Test:**
   - Complete quiz with specific answers
   - Generate plan
   - Verify plan structure matches quiz answers (e.g., if you selected "Tutorial - How-to guide", the plan should be tutorial-style)

## Configuration Examples

### Example 1: Marketing Blog
**Settings:**
- Confidence Threshold: 0.6 (Sensitive)
- Required Categories: Target Outcome, Target Audience, Tone, Content Type

**Result:** Quiz will ask 4 focused questions about marketing goals and audience.

### Example 2: Technical Documentation
**Settings:**
- Confidence Threshold: 0.5 (Very Sensitive)
- Required Categories: All categories

**Result:** Comprehensive quiz covering all 7 categories to ensure technical accuracy.

### Example 3: Quick Blog Posts
**Settings:**
- Confidence Threshold: 0.8 (Strict)
- Required Categories: Target Audience, Tone

**Result:** Minimal quiz, only appears when very unclear. Fast workflow.

---

## Database Migration

No database migration needed. All settings use WordPress options API with sensible defaults:

```php
// New settings with defaults
$settings['enable_clarification_quiz'] = true;
$settings['clarity_confidence_threshold'] = '0.6';
$settings['required_context_categories'] = array(
    'target_outcome',
    'target_audience',
    'tone',
    'content_depth',
    'expertise_level',
    'content_type',
    'pov',
);
```

Settings will be created automatically on first save.

---

## Rollback Plan

If issues occur, revert in this order:

1. **Revert settings changes** in `class-settings.php`
   - Lines 233, 246-256, 280-291, 537-633

2. **Revert system prompt** in `class-gutenberg-sidebar.php`
   - Restore original 3-criteria check (topic, audience, scope)
   - Restore hardcoded 0.8 threshold

3. **Revert fallback method**
   - Remove `get_default_clarification_questions()` method
   - Restore "assume clear" error handling

4. **Revert clarification integration**
   - Remove `$clarification_answers` parameter
   - Remove context building code

---

## Success Metrics

✅ **Settings UI** - 3 new fields with proper sanitization
✅ **Configurable threshold** - Dynamic value from settings (0.6 default)
✅ **7 context categories** - Expanded from 3
✅ **Predefined options only** - No open_text questions
✅ **Fallback questions** - Works even when AI fails
✅ **Plan integration** - Clarification answers inform article structure
✅ **Error logging** - All errors logged for debugging
✅ **Backward compatible** - No breaking changes to existing functionality

---

## Next Steps

The backend implementation is **complete and functional**. The clarification quiz will now:

1. ✅ Appear more frequently (60% threshold vs 80%)
2. ✅ Ask better questions with predefined options
3. ✅ Gather comprehensive context (7 categories)
4. ✅ Use fallback when AI fails
5. ✅ Pass answers to plan generation for better articles

**Optional frontend enhancements** can be added later for improved UX, but are not required for the system to work.
