        "effectiveness_score": float,  # Cached score
        # ... existing fields
    }
}
```

### Optimization Types

#### Pattern Improvement
```python
{
    "type": "pattern_improvement",
    "patterns": {
        "section_name": ["new_pattern_1", "new_pattern_2"]
    }
}
```

#### Preference Tuning
```python
{
    "type": "preference_tuning",
    "preferences": {
        "setting_name": "new_value",
        "another_setting": true
    }
}
```

{
    "type": "rule_refinement",
    "syntax_rules": {
        "category_name": {
            "patterns": ["regex_pattern"],
            "description": "Rule description"
        }
    }
}
```

## Error Handling

### Common Error Types

#### Memory Service Errors
```python
{
    "success": False,
    "error": "Memory service not available"
}
```

#### Learning Engine Errors
```python
{
    "success": False,
    "error": "Analysis failed: {detailed_error_message}"
}
```

#### Optimization Errors
```python
{
    "success": False,
    "error": "Auto-optimization failed: {detailed_error_message}",
    "context_name": str,
    "backup_file": str  # If backup was created
}
```

### Error Recovery

All optimization operations create backups before modification:

```python
backup_file = f"backup_{context_name}_context_{timestamp}.json"
```

Failed operations preserve the original context file and provide the backup location for manual recovery.

### Validation Errors

Context optimization includes comprehensive validation:

```python
{
    "success": False,
    "error": "Optimized context validation failed",
    "validation_errors": List[str],
    "backup_file": str
}
```

## Performance Considerations

### Memory Service Calls

- All memory operations are asynchronous
- Failed memory calls don't block context operations
- Memory unavailability gracefully degrades functionality

### Learning Engine Performance

- Effectiveness analysis cached for 1 hour
- Optimization suggestions computed on-demand
- Session learning runs asynchronously during initialization

### Context Optimization

- Atomic operations with backup-first approach
- Validation before applying changes
- Automatic rollback on validation failure

## Integration Examples

### Basic Learning Workflow

```python
# Initialize provider with learning engine
provider = ContextProvider()

# Analyze context effectiveness
effectiveness = await provider.learning_engine.analyze_context_effectiveness("terraform")

# Get optimization suggestions
suggestions = await provider.learning_engine.suggest_context_optimizations()

# Apply automatic optimization
optimization_data = {
    "type": "preference_tuning",
    "preferences": {"default_region": "us-west-2"}
}
result = await provider.auto_optimize_context("terraform", optimization_data)
```

### Memory Integration Pattern

```python
# Store learning event
await provider.memory_service.store_memory(
    "Successfully optimized terraform context preferences",
    ["optimization", "terraform", "preferences"],
    {"optimization_type": "preference_tuning", "score_improvement": 0.2}
)

# Retrieve related memories
memories = await provider.memory_service.recall_memory(
    "terraform optimization",
    n_results=5
)
```
