code-reviewer

code-reviewer is a skill for Claude Code from u9401066/template-is-all-you-need. It costs 89 tokens per session (1,710 once invoked), scanned A, original, Apache-2.0.

A broad code review guide that checks source code for quality, security, performance, and common development practices. It can review files, folders, features, recent changes, or a pull request—a proposed change submitted for review.

In plain words
What is it for?
Use it to review Python projects or proposed changes, including checks for SQL injection, cross-site scripting, exposed secrets, unsafe paths, database-query problems, naming, complexity, and duplication.
Why use it?
It brings several review checks into one process, helping find unclear code, security risks, slow patterns, duplicated logic, and unused code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

code-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

程式碼審查技能

描述

對程式碼進行全面審查,檢查品質、安全性、效能和最佳實踐。

觸發條件

  • 「review 這段程式碼」「CR」「審查」
  • 「檢查程式碼」「看一下」「幫看」
  • 「code review」「PR review」

🔧 操作步驟

Step 1: 確定審查範圍

詢問或推斷審查目標:

  • 特定檔案:read_file("path/to/file.py")
  • 整個目錄:grep_search 取得概覽
  • 特定功能:semantic_search("功能名稱")
  • 最近變更:get_changed_files()

Step 2: 執行靜態分析(Python 專案)

# Ruff - 快速 linter (取代 flake8 + isort + pyupgrade)
uv run ruff check src/ --output-format=concise

# Mypy - 型別檢查
uv run mypy src/ --ignore-missing-imports

# Bandit - 安全性檢查
uv run bandit -r src/ -ll

# Vulture - 死碼偵測
uv run vulture src/ --min-confidence 80

Step 3: 審查程式碼品質

檢查項目 標準 工具輔助
命名清晰度 名稱應描述用途 人工審查
函數長度 < 50 行 grep_search
類別大小 < 300 行 grep_search
複雜度 McCabe < 10 ruff --select=C901
DRY 原則 無重複程式碼 semantic_search
SOLID 原則 單一職責等 人工審查

Step 4: 審查安全性

風險類型 檢查方式 嚴重程度
SQL 注入 搜尋 raw SQL 🔴 Critical
XSS 搜尋未轉義輸出 🔴 Critical
硬編碼密碼 grep "password|secret|key" 🔴 Critical
路徑遍歷 搜尋未驗證路徑 🟠 High
日誌洩漏 搜尋敏感資料輸出 🟡 Medium

Step 5: 審查效能

問題類型 偵測方式
N+1 查詢 搜尋迴圈內的 DB 呼叫
無謂迴圈 審查巢狀迴圈
記憶體洩漏 檢查資源釋放
阻塞操作 審查 I/O 操作

Step 6: 審查 DDD 架構

參考 ddd-architect 規則:

  • Domain 層是否有外部依賴?
  • Repository Interface 是否在 Domain 層?
  • Application 層是否過度膨脹?

Step 7: 產生審查報告


📊 審查報告格式

# 程式碼審查報告

📁 審查範圍:`src/domain/`, `src/application/`
📅 日期:2026-01-15
👤 審查者:AI Assistant

## 📈 總覽

| 指標 | 分數 | 說明 |
| ---- | ---- | ---- |
| 品質 | 8/10 | 命名清晰,部分函數過長 |
| 安全 | 9/10 | 無明顯漏洞 |
| 效能 | 7/10 | 存在 N+1 查詢風險 |
| 架構 | 8/10 | 符合 DDD,但有小違規 |

---

## ✅ 優點

1. **清晰的領域模型**:User entity 封裝良好
2. **完整的錯誤處理**:使用自定義例外
3. **良好的測試覆蓋**:核心邏輯有單元測試

---

## ⚠️ 問題發現

### 🔴 Critical (必須修復)

#### 1. SQL 注入風險
- **位置**:[user_repository.py](src/infrastructure/repositories/user_repository.py#L45)
- **問題**:使用字串拼接建立 SQL
- **建議**:使用參數化查詢

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
