Fallback Selection Logic

def select_fallback_persona(requested_persona, available_personas, error_context):
    # Persona mapping for fallbacks
    fallback_mapping = {
        "pm": "generic_pm",
        "product-manager": "generic_pm", 
        "dev": "generic_dev",
        "developer": "generic_dev",
        "analyst": "generic_analyst",
        "architect": "generic_architect",
        "design-architect": "generic_design_architect",
        "po": "generic_pm",  # PO falls back to PM
        "sm": "generic_dev"  # SM falls back to Dev
    }
    
    # Try direct fallback mapping
    primary_fallback = fallback_mapping.get(requested_persona.lower())
    
    if primary_fallback and is_available(primary_fallback):
        return primary_fallback
    
    # If multiple personas are unavailable, use troubleshooting assistant
    unavailable_count = count_unavailable_personas(available_personas)
    if unavailable_count >= 2:
        return "troubleshooting_assistant"
    
    # Try fuzzy matching with available personas
    fuzzy_match = find_closest_available_persona(requested_persona, available_personas)
    if fuzzy_match and similarity_score(requested_persona, fuzzy_match) > 0.6:
        return fuzzy_match
    
    # Last resort - troubleshooting assistant
    return "troubleshooting_assistant"

Fallback Activation Process

def activate_fallback_persona(fallback_persona, original_request, error_context):
    # Load fallback persona definition
    fallback_definition = load_fallback_persona(fallback_persona)
    
    # Create activation context with limitations

        "persona": fallback_definition,
        "original_request": original_request,
        "limitations": fallback_definition.limitations,
        "capabilities": fallback_definition.capabilities,
        "fallback_reason": error_context.reason,
        "recovery_suggestions": generate_recovery_suggestions(original_request)
    }
    
    # Notify user of fallback mode
    fallback_notification = f"""
    ⚠️ **Fallback Mode Active**

    return {
        "persona": fallback_definition,
        "context": activation_context,
        "notification": fallback_notification
    }

Fallback Quality Assurance

def validate_fallback_effectiveness(fallback_session):
    quality_metrics = {
        "user_satisfaction": measure_user_satisfaction(fallback_session),
        "task_completion": assess_task_completion_rate(fallback_session),
        "limitation_impact": evaluate_limitation_impact(fallback_session),
        "recovery_success": track_recovery_attempts(fallback_session)
    }
    
    # Log fallback performance for improvement
    fallback_memory = {
        "type": "fallback_performance",
        "fallback_persona": fallback_session.persona_name,
        "original_request": fallback_session.original_request,
        "session_duration": fallback_session.duration,
        "quality_metrics": quality_metrics,
        "improvement_suggestions": generate_improvement_suggestions(quality_metrics)
    }
    
    # Store for future fallback optimization
    if memory_system_available():
        add_memories(
            content=json.dumps(fallback_memory),
            tags=["fallback", "performance", fallback_session.persona_name],
            metadata={"type": "fallback_analysis"}
        )

Fallback Improvement Learning

def learn_from_fallback_usage():
    # Analyze fallback usage patterns
    fallback_memories = search_memory(
        "fallback_performance effectiveness user_satisfaction",
        limit=20,
        threshold=0.5
    )
    
    insights = {
        "most_effective_fallbacks": identify_effective_fallbacks(fallback_memories),
        "common_limitation_complaints": extract_limitation_issues(fallback_memories),
        "successful_workarounds": find_successful_workarounds(fallback_memories),
        "recovery_pattern_success": analyze_recovery_patterns(fallback_memories)
    }
    
    # Update fallback personas based on learnings
    for insight in insights.improvement_opportunities:
        update_fallback_persona(insight.persona, insight.improvements)
    
    return insights

This fallback persona system ensures that BMAD can continue operating with reduced but functional capabilities even when primary persona files are unavailable, while continuously learning to improve the fallback experience.
