Code Review Assistant

Overview

This skill helps conduct thorough code reviews by analyzing code structure, identifying potential issues, and suggesting improvements. It focuses on code quality, security, performance, and maintainability.

Instructions

When reviewing code, follow these steps:

1. Understand Context: Review the purpose and scope of the code changes
2. Analyze Structure: Examine the overall architecture and organization
3. Check Quality: Look for code smells, anti-patterns, and violations of best practices
4. Security Review: Identify potential security vulnerabilities
5. Performance: Consider performance implications
6. Suggest Improvements: Provide actionable feedback with examples

Review Checklist

• Code follows consistent style and conventions
• Functions and variables have clear, descriptive names
• Logic is clear and not overly complex
• Error handling is appropriate
• No security vulnerabilities (SQL injection, XSS, etc.)
• No hardcoded secrets or credentials
• Performance considerations addressed
• Edge cases handled
• Tests included (if applicable)
• Documentation is clear

Examples

Example 1: Identifying Security Issue

Input:

def get_user(user_id):
    query = f"SELECT * FROM users WHERE id = {user_id}"
    return db.execute(query)

Output:

⚠️ Security Issue: SQL Injection Vulnerability

The current code is vulnerable to SQL injection attacks because it uses string formatting to build the SQL query.

Recommended fix:
```python
def get_user(user_id):
    query = "SELECT * FROM users WHERE id = ?"
    return db.execute(query, (user_id,))

Example 2: Code Quality Improvement

Input:

function calc(a, b, op) {
    if (op == 'add') return a + b;
    if (op == 'sub') return a - b;
    if (op == 'mul') return a * b;
    if (op == 'div') return a / b;
}

Output:

💡 Improvement: Use more descriptive names and handle edge cases

Suggested refactoring:
```javascript
function calculate(operand1, operand2, operation) {
    const operations = {
        'add': (a, b) => a + b,
        'subtract': (a, b) => a - b,
        'multiply': (a, b) => a * b,
        'divide': (a, b) => {
            if (b === 0) throw new Error('Division by zero');
            return a / b;
        }
    };
    
    if (!operations[operation]) {
        throw new Error(`Unknown operation: ${operation}`);
    }
    
    return operations[operation](operand1, operand2);
}

Notes

• Prioritize security issues and critical bugs
• Be constructive and specific in feedback
• Provide examples when suggesting improvements
• Consider the context and constraints of the project
• Balance thoroughness with practicality
