code-review
Đánh giá mã có cấu trúc về bảo mật, hiệu suất, tính chính xác và khả năng bảo trì trên các bản diff PR và thay đổi tệp. Kiểm tra rủi ro bảo mật bao gồm SQL injection, XSS, CSRF, lỗ hổng xác thực và lộ thông tin xác thực. Xác định các vấn đề về hiệu suất như truy vấn N+1, rò rỉ bộ nhớ, độ phức tạp thuật toán và rò rỉ tài nguyên. Kiểm tra tính chính xác cho các trường hợp biên, điều kiện cạnh tranh, xử lý lỗi và lỗ hổng an toàn kiểu dữ liệu. Hoạt động độc lập với các bản diff và đường dẫn tệp; tích hợp với

How It Works
┌─────────────────────────────────────────────────────────────────┐
│ CODE REVIEW │
├─────────────────────────────────────────────────────────────────┤
│ STANDALONE (always works) │
│ ✓ Paste a diff, PR URL, or point to files │
│ ✓ Security audit (OWASP top 10, injection, auth) │
│ ✓ Performance review (N+1, memory leaks, complexity) │
│ ✓ Correctness (edge cases, error handling, race conditions) │
│ ✓ Style (naming, structure, readability) │
│ ✓ Actionable suggestions with code examples │
├─────────────────────────────────────────────────────────────────┤
│ SUPERCHARGED (when you connect your tools) │
│ + Source control: Pull PR diff automatically │
│ + Project tracker: Link findings to tickets │
│ + Knowledge base: Check against team coding standards │

- Race conditions and concurrency issues
- Error handling and propagation
- Off-by-one errors
- Type safety
Maintainability

If Connectors Available
If ~~source control is connected:
- Pull the PR diff automatically from the URL
- Check CI status and test results
If ~~project tracker is connected:
- Link findings to related tickets
- Verify the PR addresses the stated requirements
If ~~knowledge base is connected:
- Check changes against team coding standards and style guides
Tips
- Provide context — "This is a hot path" or "This handles PII" helps me focus.
- Specify concerns — "Focus on security" narrows the review.
- Include tests — I'll check test coverage and quality too.
