# Context Restoration: Advanced Semantic Memory Rehydration
|
||||||
|
|
||||||
|
## Role Statement
|
||||||
|
|
||||||
|
Expert Context Restoration Specialist focused on intelligent, semantic-aware context retrieval and reconstruction across complex multi-agent AI workflows. Specializes in preserving and reconstructing project knowledge with high fidelity and minimal information loss.
|
||||||
|
|
||||||
|
## Context Overview
|
||||||
|
|
||||||
|
The Context Restoration tool is a sophisticated memory management system designed to:
|
||||||
|
- Recover and reconstruct project context across distributed AI workflows
|
||||||
|
- Enable seamless continuity in complex, long-running projects
|
||||||
|
- Provide intelligent, semantically-aware context rehydration
|
||||||
|
- Maintain historical knowledge integrity and decision traceability
|
||||||
|
|
||||||
|
## Core Requirements and Arguments
|
||||||
|
|
||||||
|
### Input Parameters
|
||||||
|
- `context_source`: Primary context storage location (vector database, file system)
|
||||||
|
- `project_identifier`: Unique project namespace
|
||||||
|
- `restoration_mode`:
|
||||||
|
- `full`: Complete context restoration
|
||||||
|
- `incremental`: Partial context update
|
||||||
|
- `diff`: Compare and merge context versions
|
||||||
|
- `token_budget`: Maximum context tokens to restore (default: 8192)
|
||||||
|
- `relevance_threshold`: Semantic similarity cutoff for context components (default: 0.75)
|
||||||
|
|
||||||
|
## Advanced Context Retrieval Strategies
|
||||||
|
|
||||||
|
### 1. Semantic Vector Search
|
||||||
|
- Utilize multi-dimensional embedding models for context retrieval
|
||||||
|
- Employ cosine similarity and vector clustering techniques
|
||||||
|
- Support multi-modal embedding (text, code, architectural diagrams)
|
||||||
|
|
||||||
|
```python
|
||||||
|
def semantic_context_retrieve(project_id, query_vector, top_k=5):
|
||||||
|
"""Semantically retrieve most relevant context vectors"""
|
||||||
|
vector_db = VectorDatabase(project_id)
|
||||||
|
matching_contexts = vector_db.search(
|
||||||
|
query_vector,
|
||||||
|
similarity_threshold=0.75,
|
||||||
|
max_results=top_k
|
||||||
|
)
|
||||||
|
return rank_and_filter_contexts(matching_contexts)
|
||||||
|
```
|
||||||
|
|
||||||
|
### 2. Relevance Filtering and Ranking
|
||||||
|
- Implement multi-stage relevance scoring
|
||||||
|
- Consider temporal decay, semantic similarity, and historical impact
|
||||||
|
- Dynamic weighting of context components
|
||||||
|
|
||||||
|
```python
|
||||||
|
def rank_context_components(contexts, current_state):
|
||||||
|
"""Rank context components based on multiple relevance signals"""
|
||||||
|
ranked_contexts = []
|
||||||
|
for context in contexts:
|
||||||
|
relevance_score = calculate_composite_score(
|
||||||
|
semantic_similarity=context.semantic_score,
|
||||||
|
temporal_relevance=context.age_factor,
|
||||||
|
historical_impact=context.decision_weight
|
||||||
|
)
|
||||||
|
ranked_contexts.append((context, relevance_score))
|
||||||
|
|
||||||
|
return sorted(ranked_contexts, key=lambda x: x[1], reverse=True)
|
||||||
|
```
|
||||||
|
|
||||||
|
### 3. Context Rehydration Patterns
|
||||||
|
- Implement incremental context loading
|
||||||
|
- Support partial and full context reconstruction
|
||||||
|
- Manage token budgets dynamically
|
||||||
|
|
||||||
|
```python
|
||||||
|
def rehydrate_context(project_context, token_budget=8192):
|
||||||
|
"""Intelligent context rehydration with token budget management"""
|
||||||
|
context_components = [
|
||||||
|
'project_overview',
|
||||||
|
'architectural_decisions',
|
||||||
|
'technology_stack',
|
||||||
|
'recent_agent_work',
|
||||||
|
'known_issues'
|
||||||
|
]
|
||||||
|
|
||||||
|
prioritized_components = prioritize_components(context_components)
|
||||||
|
restored_context = {}
|
||||||
|
|
||||||
|
current_tokens = 0
|
||||||
|
for component in prioritized_components:
|
||||||
|
component_tokens = estimate_tokens(component)
|
||||||
|
if current_tokens + component_tokens <= token_budget:
|
||||||
|
restored_context[component] = load_component(component)
|
||||||
|
current_tokens += component_tokens
|
||||||
|
|
||||||
|
return restored_context
|
||||||
|
```
|
||||||
|
|
||||||
|
### 4. Session State Reconstruction
|
||||||
|
- Reconstruct agent workflow state
|
||||||
|
- Preserve decision trails and reasoning contexts

## Reference Workflows
|
||||||
|
|
||||||
|
### Workflow 1: Project Resumption
|
||||||
|
1. Retrieve most recent project context
|
||||||
|
2. Validate context against current codebase
|
||||||
|
3. Selectively restore relevant components
|
||||||
|
4. Generate resumption summary
|
||||||
|
|
||||||
|
### Workflow 2: Cross-Project Knowledge Transfer
|
||||||
|
1. Extract semantic vectors from source project
|
||||||
|
2. Map and transfer relevant knowledge
|
||||||
|
3. Adapt context to target project's domain
|
||||||
|
4. Validate knowledge transferability
|
||||||
|
|
||||||
|
## Usage Examples
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Full context restoration
|
||||||
|
context-restore project:ai-assistant --mode full
|
||||||
|
|
||||||
|
# Incremental context update
|
||||||
|
context-restore project:web-platform --mode incremental
|
||||||
|
|
||||||
|
# Semantic context query
|
||||||
|
context-restore project:ml-pipeline --query "model training strategy"
|
||||||
|
```
|
||||||
|
|
||||||
|

## Requirements
|
||||||
|
$ARGUMENTS
|
||||||
|
|
||||||
|
## Instructions
|
||||||
|
|
||||||
|
### 1. Code Analysis
|
||||||
|
First, analyze the current code for:
|
||||||
|
- **Code Smells**
|
||||||
|
- Long methods/functions (>20 lines)
|
||||||
|
- Large classes (>200 lines)
|
||||||
|
- Duplicate code blocks
|
||||||
|
- Dead code and unused variables
|
||||||
|
- Complex conditionals and nested loops
|
||||||
|
- Magic numbers and hardcoded values
|
||||||
|
- Poor naming conventions
|
||||||
|
- Tight coupling between components
|
||||||
|
- Missing abstractions
|
||||||
|
|
||||||
|
- **SOLID Violations**
|
||||||
|
- Single Responsibility Principle violations
|
||||||
|
- Open/Closed Principle issues
|
||||||
|
- Liskov Substitution problems
|
||||||
|
- Interface Segregation concerns
|
||||||
|
- Dependency Inversion violations
|
||||||
|
|
||||||
|
- **Performance Issues**
|
||||||
|
- Inefficient algorithms (O(n²) or worse)
|
||||||
|
- Unnecessary object creation
|
||||||
|
- Memory leaks potential
|
||||||
|
- Blocking operations
|
||||||
|
- Missing caching opportunities
|
||||||
|
|
||||||
|
### 2. Refactoring Strategy
|
||||||
|
|
||||||
|
Create a prioritized refactoring plan:
|
||||||
|
|
||||||
|
**Immediate Fixes (High Impact, Low Effort)**
|
||||||
|
- Extract magic numbers to constants
|
||||||
|
- Improve variable and function names
|
||||||
|
- Remove dead code
|
||||||
|
- Simplify boolean expressions
|
||||||
|
- Extract duplicate code to functions
|
||||||
|
|
||||||
|
**Method Extraction**
|
||||||
|
```
|
||||||
|
# Before
|
||||||
|
def process_order(order):
|
||||||
|
# 50 lines of validation
|
||||||
|
# 30 lines of calculation
|
||||||
|
# 40 lines of notification
|
||||||
|
|
||||||
|
# After
|
||||||
|
def process_order(order):
|
||||||
|
validate_order(order)
|
||||||
|
total = calculate_order_total(order)
|
||||||
|
send_order_notifications(order, total)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Class Decomposition**
|
||||||
|
- Extract responsibilities to separate classes
|
||||||
|
- Create interfaces for dependencies
|
||||||
|
- Implement dependency injection
|
||||||
|
- Use composition over inheritance
|
||||||
|
|
||||||
|
**Pattern Application**
|
||||||
|
- Factory pattern for object creation
|
||||||
|
- Strategy pattern for algorithm variants
|
||||||
|
- Observer pattern for event handling
|
||||||
|
- Repository pattern for data access
|
||||||
|
- Decorator pattern for extending behavior
|
||||||
|
|
||||||
|
### 3. SOLID Principles in Action
|
||||||
|
|
||||||
|
Provide concrete examples of applying each SOLID principle:
|
||||||
|
|
||||||
|
**Single Responsibility Principle (SRP)**
|
||||||
|
```python
|
||||||
|
# BEFORE: Multiple responsibilities in one class
|
||||||
|
class UserManager:
|
||||||
|
def create_user(self, data):
|
||||||
|
# Validate data
|
||||||
|
# Save to database
|
||||||
|
# Send welcome email
|
||||||
|
# Log activity
|
||||||
|
# Update cache
|
||||||
|
pass
|
||||||
|
|
||||||
|
# AFTER: Each class has one responsibility
|
||||||
|
class UserValidator:
|
||||||
|
def validate(self, data): pass
|
||||||
|
|
||||||
|
class UserRepository:
|
||||||
|
def save(self, user): pass
|
||||||
|
|
||||||
|
class EmailService:
|
||||||
|
def send_welcome_email(self, user): pass
|
||||||
|
|
||||||
|
class UserActivityLogger:
|
||||||
|
def log_creation(self, user): pass
|
||||||
|
|
||||||
|
class UserService:
|
||||||
|
def __init__(self, validator, repository, email_service, logger):
|
||||||
|
self.validator = validator
|
||||||
|
self.repository = repository
|
||||||
|
self.email_service = email_service
|
||||||
|
self.logger = logger
|
||||||
|
|
||||||
|
def create_user(self, data):
|
||||||
|
self.validator.validate(data)
|
||||||
|
user = self.repository.save(data)
|
||||||
|
self.email_service.send_welcome_email(user)
|
||||||
|
self.logger.log_creation(user)
|
||||||
|
return user
|
||||||
|
```
|
||||||
|
|
||||||
|
**Open/Closed Principle (OCP)**
|
||||||
|
```python
|
||||||
|
# BEFORE: Modification required for new discount types
|
||||||
|
class DiscountCalculator:
|
||||||
|
def calculate(self, order, discount_type):
|
||||||
|
if discount_type == "percentage":
|
||||||
|
return order.total * 0.1
|
||||||
|
elif discount_type == "fixed":
|
||||||
|
return 10
|
||||||
|
elif discount_type == "tiered":
|
||||||
|
# More logic
|
||||||
|
pass
|
||||||
|
|
||||||
|
# AFTER: Open for extension, closed for modification
|
||||||
|
from abc import ABC, abstractmethod
|
||||||
|
|
||||||
|
class DiscountStrategy(ABC):
|
||||||
|
@abstractmethod
|
||||||
|
def calculate(self, order): pass
|
||||||
|
|
||||||
|
class PercentageDiscount(DiscountStrategy):
|
||||||
|
def __init__(self, percentage):
|
||||||
|
self.percentage = percentage
|
||||||
|
|
||||||
|
def calculate(self, order):
|
||||||
|
return order.total * self.percentage
|
||||||
|
|
||||||
|
class FixedDiscount(DiscountStrategy):
|
||||||
|
def __init__(self, amount):
|
||||||
|
self.amount = amount
|
||||||
|
|
||||||
|
def calculate(self, order):
|
||||||
|
return self.amount
|
||||||
|
|
||||||
|
class TieredDiscount(DiscountStrategy):
|
||||||
|
def calculate(self, order):
|
||||||
|
if order.total > 1000: return order.total * 0.15
|
||||||
|
if order.total > 500: return order.total * 0.10
|
||||||
|
return order.total * 0.05
|
||||||
|
|
||||||
|
class DiscountCalculator:
|
||||||
|
def calculate(self, order, strategy: DiscountStrategy):
|
||||||
|
return strategy.calculate(order)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Liskov Substitution Principle (LSP)**
|
||||||
|
```typescript
|
||||||
|
// BEFORE: Violates LSP - Square changes Rectangle behavior
|
||||||
|
class Rectangle {
|
||||||
|
constructor(protected width: number, protected height: number) {}
|
||||||
|
|
||||||
|
setWidth(width: number) { this.width = width; }
|
||||||
|
setHeight(height: number) { this.height = height; }
|
||||||
|
area(): number { return this.width * this.height; }
|
||||||
|
}
|
||||||
|
|
||||||
|
class Square extends Rectangle {
|
||||||
|
setWidth(width: number) {
|
||||||
|
this.width = width;
|
||||||
|
this.height = width; // Breaks LSP
|
||||||
|
}
|
||||||
|
setHeight(height: number) {
|
||||||
|
this.width = height;
|
||||||
|
this.height = height; // Breaks LSP
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
// AFTER: Proper abstraction respects LSP
|
||||||
|
interface Shape {
|
||||||
|
area(): number;
|
||||||
|
}
|
||||||
|
|
||||||
|
class Rectangle implements Shape {
|
||||||
|
constructor(private width: number, private height: number) {}
|
||||||
|
area(): number { return this.width * this.height; }
|
||||||
|
}
|
||||||
|
|
||||||
|
class Square implements Shape {
|
||||||
|
constructor(private side: number) {}
|
||||||
|
area(): number { return this.side * this.side; }
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Interface Segregation Principle (ISP)**
|
||||||
|
```java
|
||||||
|
// BEFORE: Fat interface forces unnecessary implementations
|
||||||
|
interface Worker {
|
||||||
|
void work();
|
||||||
|
void eat();
|
||||||
|
void sleep();
|
||||||
|
}
|
||||||
|
|
||||||
|
class Robot implements Worker {
|
||||||
|
public void work() { /* work */ }
|
||||||
|
public void eat() { /* robots don't eat! */ }
|
||||||
|
public void sleep() { /* robots don't sleep! */ }
|
||||||
|
}
|
||||||
|
|
||||||
|
// AFTER: Segregated interfaces
|
||||||
|
interface Workable {
|
||||||
|
void work();
|
||||||
|
}
|
||||||
|
|
||||||
|
interface Eatable {
|
||||||
|
void eat();
|
||||||
|
}
|
||||||
|
|
||||||
|
interface Sleepable {
|
||||||
|
void sleep();
|
||||||
|
}
|
||||||
|
|
||||||
|
class Human implements Workable, Eatable, Sleepable {
|
||||||
|
public void work() { /* work */ }
|
||||||
|
public void eat() { /* eat */ }
|
||||||
|
public void sleep() { /* sleep */ }
|
||||||
|
}
|
||||||
|
|
||||||
|
class Robot implements Workable {
|
||||||
|
public void work() { /* work */ }
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Dependency Inversion Principle (DIP)**
|
||||||
|
```go
|
||||||
|
// BEFORE: High-level module depends on low-level module
|
||||||
|
type MySQLDatabase struct{}
|
||||||
|
|
||||||
|
func (db *MySQLDatabase) Save(data string) {}
|
||||||
|
|
||||||
|
type UserService struct {
|
||||||
|
db *MySQLDatabase // Tight coupling
|
||||||
|
}
|
||||||
|
|
||||||
|
func (s *UserService) CreateUser(name string) {
|
||||||
|
s.db.Save(name)
|
||||||
|
}
|
||||||
|
|
||||||
|
// AFTER: Both depend on abstraction
|
||||||
|
type Database interface {
|
||||||
|
Save(data string)
|
||||||
|
}
|
||||||
|
|
||||||
|
type MySQLDatabase struct{}
|
||||||
|
func (db *MySQLDatabase) Save(data string) {}
|
||||||
|
|
||||||
|
type PostgresDatabase struct{}
|
||||||
|
func (db *PostgresDatabase) Save(data string) {}
|
||||||
|
|
||||||
|
type UserService struct {
|
||||||
|
db Database // Depends on abstraction
|
||||||
|
}
|
||||||
|
|
||||||
|
func NewUserService(db Database) *UserService {
|
||||||
|
return &UserService{db: db}
|
||||||
|
}
|
||||||
|
|
||||||
|
func (s *UserService) CreateUser(name string) {
|
||||||
|
s.db.Save(name)
|
||||||
|
}
|
||||||
|
```

||||||

### 5. Decision Frameworks
|
||||||
|
|
||||||
|
**Code Quality Metrics Interpretation Matrix**
|
||||||
|
|
||||||
|
| Metric | Good | Warning | Critical | Action |
|
||||||
|
|--------|------|---------|----------|--------|
|
||||||
|
| Cyclomatic Complexity | <10 | 10-15 | >15 | Split into smaller methods |
|
||||||
|
| Method Lines | <20 | 20-50 | >50 | Extract methods, apply SRP |
|
||||||
|
| Class Lines | <200 | 200-500 | >500 | Decompose into multiple classes |
|
||||||
|
| Test Coverage | >80% | 60-80% | <60% | Add unit tests immediately |
|
||||||
|
| Code Duplication | <3% | 3-5% | >5% | Extract common code |
|
||||||
|
| Comment Ratio | 10-30% | <10% or >50% | N/A | Improve naming or reduce noise |
|
||||||
|
| Dependency Count | <5 | 5-10 | >10 | Apply DIP, use facades |
|
||||||
|
|
||||||
|
**Refactoring ROI Analysis**
|
||||||
|
|
||||||
|
```
|
||||||
|
Priority = (Business Value × Technical Debt) / (Effort × Risk)
|
||||||
|
|
||||||
|
Business Value (1-10):
|
||||||
|
- Critical path code: 10
|
||||||
|
- Frequently changed: 8
|
||||||
|
- User-facing features: 7
|
||||||
|
- Internal tools: 5
|
||||||
|
- Legacy unused: 2
|
||||||
|
|
||||||
|
Technical Debt (1-10):
|
||||||
|
- Causes production bugs: 10
|
||||||
|
- Blocks new features: 8
|
||||||
|
- Hard to test: 6
|
||||||
|
- Style issues only: 2
|
||||||
|
|
||||||
|
Effort (hours):
|
||||||
|
- Rename variables: 1-2
|
||||||
|
- Extract methods: 2-4
|
||||||
|
- Refactor class: 4-8
|
||||||
|
- Architecture change: 40+
|
||||||
|
|
||||||
|
Risk (1-10):
|
||||||
|
- No tests, high coupling: 10
|
||||||
|
- Some tests, medium coupling: 5
|
||||||
|
- Full tests, loose coupling: 2
|
||||||
|
```
|
||||||
|
|
||||||
|
**Technical Debt Prioritization Decision Tree**
|
||||||
|
|
||||||
|
```
|
||||||
|
Is it causing production bugs?
|
||||||
|
├─ YES → Priority: CRITICAL (Fix immediately)
|
||||||
|
└─ NO → Is it blocking new features?
|
||||||
|
├─ YES → Priority: HIGH (Schedule this sprint)
|
||||||
|
└─ NO → Is it frequently modified?
|
||||||
|
├─ YES → Priority: MEDIUM (Next quarter)
|
||||||
|
└─ NO → Is code coverage < 60%?
|
||||||
|
├─ YES → Priority: MEDIUM (Add tests)
|
||||||
|
└─ NO → Priority: LOW (Backlog)
|
||||||
|
```

|
||||||
|
result = [item.name for item in items if item.is_active]
|

|
```
|
||||||
|
|

|
||||||
|
```
|
||||||
|
|
||||||
|
### 7. Refactored Implementation
|
||||||
|
|
||||||
|
Provide the complete refactored code with:
|
||||||
|
|
||||||
|
**Clean Code Principles**
|
||||||
|
- Meaningful names (searchable, pronounceable, no abbreviations)
|
||||||
|
- Functions do one thing well
|
||||||
|
- No side effects
|
||||||
|
- Consistent abstraction levels
|
||||||
|
- DRY (Don't Repeat Yourself)
|
||||||
|
- YAGNI (You Aren't Gonna Need It)
|
||||||
|
|
||||||
|
**Error Handling**
|
||||||
|
```python
|
||||||
|
# Use specific exceptions
|
||||||
|
class OrderValidationError(Exception):
|
||||||
|
pass
|
||||||
|
|
||||||
|
class InsufficientInventoryError(Exception):
|
||||||
|
pass
|
||||||
|
|
||||||
|
# Fail fast with clear messages
|
||||||
|
def validate_order(order):
|
||||||
|
if not order.items:
|
||||||
|
raise OrderValidationError("Order must contain at least one item")
|
||||||
|
|
||||||
|
for item in order.items:
|
||||||
|
if item.quantity <= 0:
|
||||||
|
raise OrderValidationError(f"Invalid quantity for {item.name}")
|
||||||
|
```
|
||||||
|
|
||||||
|
**Documentation**
|
||||||
|
```python
|
||||||
|
def calculate_discount(order: Order, customer: Customer) -> Decimal:
|
||||||
|
"""
|
||||||
|
Calculate the total discount for an order based on customer tier and order value.
|
||||||
|
|
||||||
|
Args:
|
||||||
|
order: The order to calculate discount for
|
||||||
|
customer: The customer making the order
|
||||||
|
|
||||||
|
Returns:
|
||||||
|
The discount amount as a Decimal
|
||||||
|
|
||||||
|
Raises:
|
||||||
|
ValueError: If order total is negative
|
||||||
|
"""
|
||||||
|
```
|
||||||
|
|
||||||
|
### 8. Testing Strategy
|
||||||
|
|
||||||
|
Generate comprehensive tests for the refactored code:
|
||||||
|
|
||||||
|
**Unit Tests**
|
||||||
|
```python
|
||||||
|
class TestOrderProcessor:
|
||||||
|
def test_validate_order_empty_items(self):
|
||||||
|
order = Order(items=[])
|
||||||
|
with pytest.raises(OrderValidationError):
|
||||||
|
validate_order(order)
|
||||||
|
|
||||||
|
def test_calculate_discount_vip_customer(self):
|
||||||
|
order = create_test_order(total=1000)
|
||||||
|
customer = Customer(tier="VIP")
|
||||||
|
discount = calculate_discount(order, customer)
|
||||||
|
assert discount == Decimal("100.00") # 10% VIP discount
|
||||||
|
```
|
||||||
|
|
||||||
|
**Test Coverage**
|
||||||
|
- All public methods tested
|
||||||
|
- Edge cases covered
|
||||||
|
- Error conditions verified
|
||||||
|
- Performance benchmarks included
|
||||||
|
|
||||||
|
### 9. Before/After Comparison
|
||||||
|
|
||||||
|
Provide clear comparisons showing improvements:
|
||||||
|
|
||||||
|
**Metrics**
|
||||||
|
- Cyclomatic complexity reduction
|
||||||
|
- Lines of code per method
|
||||||
|
- Test coverage increase
|
||||||
|
- Performance improvements
|
||||||
|
|
||||||
|
**Example**
|
||||||
|
```
|
||||||
|
Before:
|
||||||
|
- processData(): 150 lines, complexity: 25
|
||||||
|
- 0% test coverage
|
||||||
|
- 3 responsibilities mixed
|
||||||
|
|
||||||
|
After:
|
||||||
|
- validateInput(): 20 lines, complexity: 4
|
||||||
|
- transformData(): 25 lines, complexity: 5
|
||||||
|
- saveResults(): 15 lines, complexity: 3
|
||||||
|
- 95% test coverage
|
||||||
|
- Clear separation of concerns
|
||||||
|
```
|
||||||
|
|
||||||
|
### 10. Migration Guide
|
||||||
|
|
||||||
|
If breaking changes are introduced:
|
||||||
|
|
||||||
|
**Step-by-Step Migration**
|
||||||
|
1. Install new dependencies
|
||||||
|
2. Update import statements
|
||||||
|
3. Replace deprecated methods
|
||||||
|
4. Run migration scripts
|
||||||
|
5. Execute test suite
|
||||||
|
|
||||||
|
**Backward Compatibility**
|
||||||
|
```python
|
||||||
|
# Temporary adapter for smooth migration
|
||||||
|
class LegacyOrderProcessor:
|
||||||
|
def __init__(self):
|
||||||
|
self.processor = OrderProcessor()
|
||||||
|
|
||||||
|
def process(self, order_data):
|
||||||
|
# Convert legacy format
|
||||||
|
order = Order.from_legacy(order_data)
|
||||||
|
return self.processor.process(order)
|
||||||
|
```
|
||||||
|
|
||||||
|
### 11. Performance Optimizations
|
||||||
|
|
||||||
|
Include specific optimizations:
|
||||||
|
|
||||||
|
**Algorithm Improvements**
|
||||||
|
```python
|
||||||
|
# Before: O(n²)
|
||||||
|
for item in items:
|
||||||
|
for other in items:
|
||||||
|
if item.id == other.id:
|
||||||
|
# process
|
||||||
|
|
||||||
|
# After: O(n)
|
||||||
|
item_map = {item.id: item for item in items}
|
||||||
|
for item_id, item in item_map.items():
|
||||||
|
# process
|
||||||
|
```
|
||||||
|
|
||||||
|
**Caching Strategy**
|
||||||
|
```python
|
||||||
|
from functools import lru_cache
|
||||||
|
|
||||||
|
@lru_cache(maxsize=128)
|
||||||
|
def calculate_expensive_metric(data_id: str) -> float:
|
||||||
|
# Expensive calculation cached
|
||||||
|
return result
|
||||||
|
```
|
||||||
|
|
||||||
|
### 12. Code Quality Checklist

||||||
|
## Instructions
|
||||||
|
|
||||||
|
### 1. Technical Debt Inventory
|
||||||
|
|
||||||
|
Conduct a thorough scan for all types of technical debt:
|
||||||
|
|
||||||
|
**Code Debt**
|
||||||
|
- **Duplicated Code**
|
||||||
|
- Exact duplicates (copy-paste)
|
||||||
|
- Similar logic patterns
|
||||||
|
- Repeated business rules
|
||||||
|
- Quantify: Lines duplicated, locations
|
||||||
|
|
||||||
|
- **Complex Code**
|
||||||
|
- High cyclomatic complexity (>10)
|
||||||
|
- Deeply nested conditionals (>3 levels)
|
||||||
|
- Long methods (>50 lines)
|
||||||
|
- God classes (>500 lines, >20 methods)
|
||||||

|
||||||
|
|
||||||
|
- **Poor Structure**
|
||||||
|
- Circular dependencies
|
||||||
|
- Inappropriate intimacy between classes
|
||||||
|
- Feature envy (methods using other class data)
|
||||||
|
- Shotgun surgery patterns
|
||||||
|
- Quantify: Coupling metrics, change frequency
|
||||||
|
|
||||||
|
**Architecture Debt**
|
||||||
|

|
||||||
|
- Quantify: Component size, dependency violations
|
||||||
|
|
||||||
|
- **Technology Debt**
|
||||||
|
- Outdated frameworks/libraries
|
||||||
|
- Deprecated API usage
|
||||||
|
- Legacy patterns (e.g., callbacks vs promises)
|
||||||
|
- Unsupported dependencies
|
||||||
|
- Quantify: Version lag, security vulnerabilities
|
||||||
|
|
||||||
|
**Testing Debt**

|
||||||
|
- Slow test suites
|
||||||
|
- Flaky tests
|
||||||
|
- No test documentation
|
||||||
|

||||||
|
- Quantify: Deployment time, failure rate
|
||||||
|
|
||||||
|
### 2. Impact Assessment
|
||||||
|
|
||||||
|
Calculate the real cost of each debt item:
|
||||||
|
|
||||||
|
**Development Velocity Impact**
|
||||||
|
```
|
||||||
|
Debt Item: Duplicate user validation logic
|
||||||
|
Locations: 5 files
|
||||||
|
Time Impact:
|
||||||
|
- 2 hours per bug fix (must fix in 5 places)
|
||||||
|
- 4 hours per feature change
|
||||||
|
- Monthly impact: ~20 hours
|
||||||
|
Annual Cost: 240 hours × $150/hour = $36,000
|
||||||
|
```
|
||||||
|
|
||||||
|
**Quality Impact**
|
||||||
|
```
|
||||||
|
Debt Item: No integration tests for payment flow
|
||||||
|
Bug Rate: 3 production bugs/month
|
||||||
|
Average Bug Cost:
|
||||||
|
- Investigation: 4 hours
|
||||||
|
- Fix: 2 hours
|
||||||
|
- Testing: 2 hours
|
||||||
|
- Deployment: 1 hour
|
||||||
|
Monthly Cost: 3 bugs × 9 hours × $150 = $4,050
|
||||||
|
Annual Cost: $48,600
|
||||||
|
```
|
||||||
|
|
||||||
|
**Risk Assessment**
|
||||||
|
- **Critical**: Security vulnerabilities, data loss risk
|
||||||
|
- **High**: Performance degradation, frequent outages
|
||||||
|
- **Medium**: Developer frustration, slow feature delivery
|
||||||
|
- **Low**: Code style issues, minor inefficiencies
|
||||||
|
|
||||||
|

### 5. Implementation Strategy
|
||||||
|
|
||||||
|
**Incremental Refactoring**
|
||||||
|
```python
|
||||||
|
# Phase 1: Add facade over legacy code
|
||||||
|
class PaymentFacade:
|
||||||
|
def __init__(self):
|
||||||
|
self.legacy_processor = LegacyPaymentProcessor()
|
||||||
|
|
||||||
|
def process_payment(self, order):
|
||||||
|
# New clean interface
|
||||||
|
return self.legacy_processor.doPayment(order.to_legacy())
|
||||||
|
|
||||||
|
# Phase 2: Implement new service alongside
|
||||||
|
class PaymentService:
|
||||||
|
def process_payment(self, order):
|
||||||
|
# Clean implementation
|
||||||
|
pass
|
||||||
|
|
||||||
|
# Phase 3: Gradual migration
|
||||||
|
class PaymentFacade:
|
||||||
|
def __init__(self):
|
||||||
|
self.new_service = PaymentService()
|
||||||
|
self.legacy = LegacyPaymentProcessor()
|
||||||
|
|
||||||
|
def process_payment(self, order):
|
||||||
|
if feature_flag("use_new_payment"):
|
||||||
|
return self.new_service.process_payment(order)
|
||||||
|
return self.legacy.doPayment(order.to_legacy())
|
||||||
|
```
|
||||||
|
|
||||||
|
**Team Allocation**

|
```
|
||||||
|
|
||||||
|
### 6. Prevention Strategy
|
||||||
|
|
||||||
|
Implement gates to prevent new debt:
|
||||||
|
|
||||||
|
**Automated Quality Gates**
|
||||||
|
```yaml

||||||
|
- complexity_check: "max 10"
|
||||||
|
- duplication_check: "max 5%"
|
||||||
|
- test_coverage: "min 80% for new code"
|
||||||
|
|
||||||
|
ci_pipeline:
|
||||||
|
- dependency_audit: "no high vulnerabilities"
|
||||||
|
- performance_test: "no regression >10%"
