## 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:**

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

# Accumulate Fisher information
for name, param in self.model.named_parameters():
fisher[name] += param.grad.data ** 2
# Normalize

return fisher
def update_with_ewc(self, new_task_data, ewc_lambda=1000):
"""
Update model on new task while preserving old skills.

# Compute EWC penalty
ewc_penalty = 0
for name, param in self.model.named_parameters():
fisher = self.fisher_information[name]
optimal = self.optimal_params[name]
# Penalty: Sum of squared differences weighted by importance
ewc_penalty += (fisher * (param - optimal) ** 2).sum()
# Total loss: new task + EWC penalty
total_loss = new_loss + ewc_lambda * ewc_penalty
# Optimize

## 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

- 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
