# Prevention-First API Guidance Enhancement **Version**: 5.1.0 Enhancement **Date**: July 11, 2025 **Status**: ✅ IMPLEMENTED - Prevention over correction approach **Priority**: High Impact - Addresses root cause of API errors --- ## Problem Analysis: Root Cause Identified ### User Insight 💡 > "One of the main reasons for the content problems is the lack of upfront understanding of API requirements. Better than to have safeguards to fix the content, would be to maximize the odds of getting it right the first time." ### Current vs. Enhanced Approach #### Before (Correction-Based) ❌ 1. **Claude generates content blindly** → Uses incorrect field names 2. **Validation catches errors** → Auto-fix attempts correction 3. **Format step fixes remaining** → Field name transformation 4. **API save with corrected data** → Success after multiple corrections #### After (Prevention-Based) ✅ 1. **Claude studies API requirements FIRST** → Understands exact field names 2. **Claude generates correct content** → Uses proper API format from start 3. **Validation confirms correctness** → Minimal or no issues found 4. **API save with correct data** → Success on first attempt --- ## Implementation: Enhanced API Guidance System ### 1. **Comprehensive API Requirements Catalog** **File**: `/src/guidance/api-requirements-catalog.js` Provides Claude with: - **Exact API field names** for each widget type - **Required vs optional fields** with clear specifications - **Data format requirements** (strings, numbers, arrays) - **Common mistakes** and how to avoid them - **Working examples** with correct field usage #### Key Features: ```javascript // Precise field mappings prevent API errors 'quiz-1': { requiredFields: { questions: { apiFieldName: 'questions', itemStructure: { options: { example: '["Option A", "Option B", "Option C"]', apiConversion: 'Converted to "answers" field in API' }, correct_option: { example: '1 (for second option)', format: 'Zero-based index of correct answer' } } } }, criticalNote: 'Use "options" array in your content - API will convert to "answers"' } ``` ### 2. **Enhanced Claude Guidance Instructions** **File**: `/dist/claude-guided-composer.js` (Lines 214-276) #### Priority Changes: - **API requirements section added FIRST** in guidance response - **Critical API rules highlighted** in instructions header - **Step 1 changed** from "Review widgets" to "Study API requirements" - **Prevention emphasis** throughout instructions #### Key Instruction Changes: ```javascript 🚨 CRITICAL: FOLLOW API REQUIREMENTS FIRST - PREVENTION OVER CORRECTION 🚨 KEY API RULES TO PREVENT ERRORS: • Quiz: Use "options" array with "correct_option" index (NOT "choices" or "answers") • List: Use "items" array (NOT "list_items") • Hotspots: Use numeric coordinates like 50, 30 (NOT strings like "50%") • Flashcards: Use "flashcards_items" with "question"/"answer" format MULTI-TOOL WORKFLOW: 1. ✅ FIRST: Study the apiRequirements section to understand exact field formats 2. Generate high-quality educational content following API requirements precisely ``` ### 3. **Common Mistakes Prevention Guide** Explicitly prevents the exact errors that caused 500 API failures: ```javascript fieldNameErrors: { quiz: { wrong: 'Using "choices" or "answers" in quiz content', correct: 'Use "options" array with "correct_option" index', consequence: '500 API error - field not found' }, list: { wrong: 'Using "list_items" in your content', correct: 'Use "items" array in your content', consequence: '500 API error - field not found' }, hotspots: { wrong: 'Using string percentages like "50%" in your content', correct: 'Use numeric coordinates like 50, 30 in your content', consequence: 'API expects numeric values to convert' } } ``` --- ## Test Results ✅ ### API Requirements Guidance Test ``` 🚨 Testing API Requirements Guidance (Prevention-First Approach) ✅ API requirements section present ✅ Quiz field requirements specified ✅ List field requirements specified ✅ Hotspots field requirements specified ✅ Common mistakes guide provided ✅ Critical reminders provided ✅ Instructions prioritize API requirements ✅ Instructions direct Claude to study API requirements first ✅ Prevention-first approach should eliminate most API errors at source ``` ### Expected Behavior Changes #### Content Generation Quality - **Field Names**: Claude should use correct field names from the start - **Data Formats**: Proper data types and structures - **Required Fields**: All mandatory fields included - **Validation**: Fewer validation errors due to correct initial format #### Workflow Efficiency - **Reduced Retry Loops**: Less back-and-forth validation - **Faster Processing**: Minimal correction needed - **Higher Success Rate**: First-attempt API success - **Better User Experience**: Smoother lesson creation --- ## API Requirements Coverage ### Widget-Specific Requirements Provided #### Quiz Widgets - ✅ **Field Name**: Use `"options"` (not `"choices"` or `"answers"`) - ✅ **Correct Answer**: Use `"correct_option"` index - ✅ **Structure**: Array of strings with numeric index - ✅ **Example**: `["A", "B", "C"]` with `correct_option: 1` #### List Widgets - ✅ **Field Name**: Use `"items"` (not `"list_items"`) - ✅ **Format**: Array of strings - ✅ **Optional**: `"list_type"` for bullet/numbered/checkbox - ✅ **Example**: `["Item 1", "Item 2", "Item 3"]` #### Hotspots Widgets - ✅ **Coordinates**: Use numeric values like `50, 30` - ✅ **Not Strings**: Avoid `"50%", "30%"` in content - ✅ **Structure**: Array of marker objects - ✅ **API Conversion**: Numbers → percentage strings automatically #### Flashcards Widgets - ✅ **Field Name**: Use `"flashcards_items"` (not `"items"`) - ✅ **Item Format**: `"question"/"answer"` or `"front"/"back"` - ✅ **Structure**: Array of card objects - ✅ **Example**: `[{"question": "Term", "answer": "Definition"}]` #### Content Requirements - ✅ **Text Length**: Minimum 20 characters for all text fields - ✅ **URLs**: Complete valid URLs starting with `https://` - ✅ **Required Fields**: Clear specification for each widget type - ✅ **Data Types**: String, number, array, object specifications --- ## Integration with Existing System ### Backwards Compatibility ✅ - **Auto-fix system retained** as safety net for edge cases - **Multi-tool architecture preserved** for error isolation - **Existing validation rules maintained** for comprehensive checking - **Field name conversion still active** in format-for-composer tool ### Layered Prevention Strategy 1. **Primary Prevention**: Comprehensive API guidance upfront 2. **Secondary Prevention**: Auto-fix validation for minor issues 3. **Error Isolation**: Multi-tool architecture for debugging 4. **Format Conversion**: Final safety net in formatting step ### Performance Benefits -
