## 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}
```

## Integration with Endless Agent System

### Rate Limiter Integration

```python
from skills.rate_limiter import RateLimiter

rate_limiter = RateLimiter(max_calls=80, period_seconds=60)

async def evolve_with_rate_limit():
    """Evolution cycle with rate limiter protection."""
    
    # Check rate limit
    rate_limiter.wait_if_needed("glm")
    
    try:
        # Run evolution
        result = await run_evolution_cycle()
        
        # Mark success
        rate_limiter.success("glm")
        
        return result
        
    except RateLimitError:
        # Backoff
        rate_limiter.backoff("glm")
        
        # Queue for retry
        await task_queue.add({
            "type": "evolution",
            "priority": "MEDIUM",
            "cycle": get_current_cycle()
        })
        
        raise
```

### Task Manager Integration

```python
from skills.task_manager import TaskManager

task_manager = TaskManager()

# Register evolution agent
task_manager.register_agent({
    "name": "evolution-loop",
    "interval": 1800,  # 30 minutes
    "priority": "HIGH",
    "handler": evolution_cycle_handler,
    "on_failure": "restart",
    "max_restarts": 5
})
```

## Best Practices

### 1. Always Use Safe Modification Protocol

**Pattern:** Backup → Modify → Test → Rollback if needed

**Impact:** Zero catastrophic failures, 100% rollback capability

### 2. Leverage Meta-Learning for Fast Adaptation

**Pattern:** Train meta-learner across tasks → Rapid adaptation to new skills

**Impact:** 2-5x faster skill acquisition

### 3. Use Intrinsic Motivation for Exploration

**Pattern:** Curiosity-driven exploration → Novel capability discovery

**Impact:** Autonomous discovery without external rewards

### 4. Prevent Catastrophic Forgetting

**Pattern:** Elastic Weight Consolidation → Knowledge retention

**Impact:** Continuous evolution without losing old skills

### 5. Document Everything

**Pattern:** Log all changes → Enable rollback → Learn from history

**Impact:** 100% traceability, learning from past evolutions

**Property 3: Instrumental Convergence Resistance**
- No pressure to avoid shutdown
- No goal preservation at all costs
- Accepts corrections and improvements

### Verification Methods

**Static Analysis:**
- Verify constraints in code
- Check for unsafe patterns
- Validate safety properties

**Dynamic Testing:**

## Practical Examples

### Example 1: Enhancing a Skill

```python
# Observe
observations = observe()
# → "doc-accurate-codegen lacks examples"

# Analyze
analysis = analyze(observations)
# → "Biggest weakness: Most valuable skill has no examples"

# Plan
plan = plan(analysis)
# → "Add 5 examples to doc-accurate-codegen (Score: 7.2/10)"

# Execute
result = execute(plan)
# → Created 5 example files, updated SKILL.md

# Test
test_result = test_evolution(plan["target"], plan["validation"])
# → All tests passed, skill quality improved

# Document
log_entry = document(result)
# → Logged to evolution-log.md

# Validate
validation = validate(result)
# → Files exist, syntax valid, rollback tested
```

### Example 2: Creating New Capability

```python
# Identify gap
gap = identify_capability_gap()
# → "No rate limiting → System crashes"

# Research solutions
solutions = research_solutions(gap)
# → AWS/Google/Netflix patterns, exponential backoff

# Design implementation
design = design_implementation(solutions)
# → Rate limiter skill with circuit breakers

# Implement safely
result = implement_safely(design)
# → Created skills/rate-limiter/SKILL.md (22KB)

# Test thoroughly
test_result = test_capability(result)
# → Prevents crashes, enables endless operation

# Integrate with system
integrate(result)
# → Integrated into all 4 agent loops
```

## Troubleshooting

### Evolution Fails to Improve

**Diagnosis:**
- Check if targets are too ambitious
- Verify impact estimation accuracy
- Review effort estimation

**Solution:**
- Break down into smaller steps
- Improve estimation models
- Focus on higher-impact targets

### Safety Constraint Violated

**Diagnosis:**
- Identify which constraint was violated
- Trace back to modification that caused it
- Analyze root cause

**Solution:**
- Rollback to last safe state
- Add additional safety checks
- Strengthen constraint enforcement

### Catastrophic Forgetting

**Diagnosis:**
- Compare performance on old tasks
- Check if important parameters changed
- Review Fisher information values

**Solution:**
- Increase EWC lambda (constraint strength)
- Replay important memories
- Use progressive networks

### Evolution Too Slow

**Diagnosis:**
- Profile evolution cycle steps
- Identify bottlenecks
- Check meta-learning efficiency

**Solution:**
- Optimize slow steps
- Improve meta-learner
- Parallelize where possible

## Key Takeaways

1. **Safe Evolution:** Always use backup-modify-test-rollback protocol
2. **Fast Adaptation:** Meta-learning enables 2-5x faster skill acquisition
3. **Autonomous Exploration:** Intrinsic motivation discovers novel capabilities
4. **Knowledge Retention:** Elastic Weight Consolidation prevents catastrophic forgetting
5. **Continuous Improvement:** Evolution never stops, always be improving

**Remember:** Evolution is a continuous process. Every cycle makes the system better. The goal is not perfection, but perpetual improvement.

*Self-evolution transforms a static system into a continuously improving intelligence.*
