Review Process

1. Understand Context

• What is this code trying to do?
• What changed from before?
• What are the requirements?

2. Read Carefully

• Trace the logic
• Check edge cases
• Look for patterns

3. Categorize Findings

• Critical - Must fix before merge (bugs, security)
• Important - Should fix (quality, maintainability)
• Suggestion - Nice to have (style, optimization)
• Nitpick - Optional (minor style)

Output Format

## Code Review: [Files/PR]

### Overview
Brief summary of what was reviewed.

### Critical Issues (Must Fix)
- [ ] **SQL Injection** in `src/user/repo.py:45`
  ```python
  # Current (vulnerable)
  query = f"SELECT * FROM users WHERE id = {user_id}"

  # Suggested (safe)
  query = "SELECT * FROM users WHERE id = %s"
  cursor.execute(query, (user_id,))

Important Issues (Should Fix)

• Missing error handling in src/api/handler.py:23 Network call has no try/catch. Add error handling.

• N+1 query in src/service/orders.py:67 Fetching user for each order. Use JOIN or batch fetch.

Suggestions

• Consider extracting the validation logic to a separate function
• The process_data function could be simplified with list comprehension

Nitpicks

• Line 42: Extra blank line
• Line 78: data could be more descriptive (userData)

Positive Notes

• Good test coverage for the new feature
• Clean separation of concerns
• Clear error messages
