code-review

作者： anthropic

針對PR差異與檔案變更，進行結構化程式碼審查，涵蓋安全性、效能、正確性與可維護性。審查安全風險，包括SQL注入、XSS、CSRF、認證缺陷與憑證暴露；識別效能問題，如N+1查詢、記憶體洩漏、演算法複雜度與資源洩漏；檢查正確性，包含邊界情況、競爭條件、錯誤處理與型別安全漏洞。可獨立運作於差異與檔案路徑，並與原始碼控制整合。

### Summary
[1-2 sentence overview of the changes and overall quality]

### Critical Issues
| # | File | Line | Issue | Severity |
|---|------|------|-------|----------|
| 1 | [file] | [line] | [description] | 🔴 Critical |

### Suggestions
| # | File | Line | Suggestion | Category |
|---|------|------|------------|----------|
| 1 | [file] | [line] | [description] | Performance |

### What Looks Good
- [Positive observations]

### Verdict
[Approve / Request Changes / Needs Discussion]

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.
