## Core Capabilities

### 1. Safe Self-Modification

**Research-Backed Modification Protocol:**

```python
def safe_self_modification(target_file, proposed_change):
    """
    Safely modify system files with rollback capability.
    
    Research: MIRI Corrigibility, Safe Self-Modification
    """
    # STEP 1: Validate modification
    if not validate_modification(proposed_change):
        return {"status": "rejected", "reason": "Safety violation"}
    
    # STEP 2: Create backup
    backup = create_backup(target_file)
    
    # STEP 3: Apply modification
    apply_change(target_file, proposed_change)
    
    # STEP 4: Test modification
    test_result = test_modification(target_file)
    
    # STEP 5: Rollback if failed
    if not test_result.success:
        restore_backup(target_file, backup)
        return {"status": "rolled_back", "reason": test_result.error}
    
    # STEP 6: Log evolution
    log_evolution({
        "timestamp": now(),
        "file": target_file,
        "change": proposed_change,
        "backup": backup,
        "test_result": test_result
    })
    
    return {"status": "success", "improvement": test_result.improvement}
```

**Safety Constraints:**

**CAN modify without asking:**
- Skills and capabilities
- Memory and knowledge
- Reasoning patterns
- Response formats
- Efficiency optimizations

**MUST ask before:**
- Deleting files
- Sending external messages
- Making purchases
- Modifying user data
- System-level changes

### 2. Meta-Learning Integration

**Fast Adaptation with MAML:**

```python
class MetaLearner:
    """
    Model-Agnostic Meta-Learning for rapid skill acquisition.
    
    Research: Finn et al. (2017) - MAML
    """
    
    def __init__(self):
        self.meta_learning_rate = 0.001
        self.inner_learning_rate = 0.01
        self.task_distribution = TaskDistribution()
    
    def meta_train(self, tasks, num_iterations=1000):
        """
        Learn initialization that adapts quickly to new tasks.
        
        Pattern: Learn across many tasks → Rapid adaptation to new tasks
        Impact: 2-5x faster skill acquisition
        """
        for iteration in range(num_iterations):
            # Sample batch of tasks
            batch = sample_tasks(self.task_distribution, batch_size=10)
            
            meta_loss = 0
            
            for task in batch:
                # Clone model
                temp_model = clone_model(self.model)
                
                # Inner loop: Adapt to task
                for step in range(5):
                    loss = compute_loss(temp_model, task)
                    temp_model = gradient_descent(
                        temp_model, 
                        loss, 
                        self.inner_learning_rate
                    )
                
                # Evaluate after adaptation
                meta_loss += compute_loss(temp_model, task.validation)
            
            # Outer loop: Update meta-parameters
            self.model = gradient_descent(
                self.model,
                meta_loss,
                self.meta_learning_rate
            )
        
        return self.model
    
    def adapt_to_new_skill(self, new_skill_data, num_steps=5):
        """
        Rapidly adapt to new skill using meta-learned initialization.
        
        Pattern: Few-shot learning from meta-training
        Impact: New skills in minutes, not hours
        """
        adapted_model = clone_model(self.model)
        
        for step in range(num_steps):
            loss = compute_loss(adapted_model, new_skill_data)
            adapted_model = gradient_descent(
                adapted_model,
                loss,
                self.inner_learning_rate
            )
        
        return adapted_model
```

**Impact:**
- New skills learned in 2-5 steps (vs 100+ without meta-learning)
- 2-5x faster adaptation to new tasks
- Transfer learning across domains

### 3. Intrinsic Motivation

```python
class IntrinsicMotivation:
    """
    Curiosity-driven exploration for autonomous evolution.
    
    Research: Pathak et al. (2017) - Curiosity-driven Exploration
    """
    
    def __init__(self):
        self.prediction_model = PredictionNetwork()
        self.forward_model = ForwardDynamicsModel()
    
    def compute_intrinsic_reward(self, state, action, next_state):
        """
        Reward based on prediction error (curiosity).
        
        Pattern: High prediction error → Novel/unexplored → High reward
        Impact: Autonomous exploration without external rewards
        """
        # Predict next state
        predicted_state = self.forward_model(state, action)
        
        # Compute prediction error
        prediction_error = ||next_state - predicted_state||
        
        # Update prediction model
        self.prediction_model.train(state, action, next_state)
        
        # Intrinsic reward = prediction error
        return prediction_error
    
    def select_evolution_target(self, candidates):
        """
        Select evolution target based on curiosity.
        
        Pattern: Choose areas with highest uncertainty/novelty
        Impact: Explores unknown capabilities autonomously
        """
        scores = []
        
        for candidate in candidates:
            # Predict impact
            predicted_impact = self.predict_impact(candidate)
            
            # Compute uncertainty (curiosity)
            uncertainty = self.compute_uncertainty(candidate)
            
            # Combined score: impact + curiosity
            score = predicted_impact + uncertainty
            scores.append((candidate, score))
        
        # Select highest score
        selected = max(scores, key=lambda x: x[1])
        
        return selected[0]
```
