# SuperClaude Framework Hooks - Shared Modules Overview

## Architecture Summary

The SuperClaude Framework Hooks shared modules provide the intelligent foundation for all 7 Claude Code hooks. These 10 shared modules implement the core SuperClaude framework patterns from RULES.md, PRINCIPLES.md, and ORCHESTRATOR.md, delivering executable intelligence that transforms static configuration into dynamic, adaptive behavior.

## Core Design Principles

### 1. **Evidence-Based Intelligence**
All modules implement measurable decision-making with metrics, performance targets, and validation cycles. No assumptions without evidence.

### 2. **Adaptive Learning System**
Cross-hook learning engine that continuously improves effectiveness through pattern recognition, user preference adaptation, and performance optimization.

### 3. **Configuration-Driven Behavior**
YAML-based configuration system supporting hot-reload, environment interpolation, and modular includes for flexible deployment.

### 4. **Performance-First Design**
Sub-200ms operation targets with intelligent caching, optimized algorithms, and resource-aware processing.

### 5. **Quality-Gated Operations**
Every operation includes validation, error handling, fallback strategies, and comprehensive logging for reliability.

## Integration Points

### Hook Integration
Each hook imports and uses shared modules for:
```python
from shared import (
    FrameworkLogic,           # Decision making
    PatternDetector,          # Pattern recognition  
    MCPIntelligence,          # Server coordination
    CompressionEngine,        # Token optimization
    LearningEngine,           # Adaptive learning
    UnifiedConfigLoader,      # Configuration
)

# Additional modules available for direct import:
from shared.intelligence_engine import IntelligenceEngine  # YAML pattern interpreter
from shared.validate_system import YAMLValidationEngine    # System health validation
from shared.logger import get_logger                       # Logging utilities
```

### SuperClaude Framework Compliance

## Usage Patterns

### Basic Hook Integration
```python

framework_logic = FrameworkLogic()
pattern_detector = PatternDetector()
mcp_intelligence = MCPIntelligence()

# Use in hook implementation
context = {...}
complexity_score = framework_logic.calculate_complexity_score(context)
detection_result = pattern_detector.detect_patterns(user_input, context, operation_data)
activation_plan = mcp_intelligence.create_activation_plan(user_input, context, operation_data)
```

### Advanced Learning Integration
```python
# Record learning events
learning_engine.record_learning_event(
    LearningType.USER_PREFERENCE,
    AdaptationScope.USER,
    context,
    pattern,
    effectiveness_score=0.85
)

# Apply learned adaptations
enhanced_recommendations = learning_engine.apply_adaptations(
    context, base_recommendations
)
```
