code-review

A command that reviews uncommitted code changes for security, quality, testing, accessibility, and maintainability issues. It reports each finding with a severity, file location, explanation, and suggested fix.

In plain words
What is it for?
Use it to inspect the current Git changes, find security flaws and code-quality problems, check tests and accessibility, and produce a review report.
Why use it?
It gives developers a structured check before committing changes. It can block approval when it finds critical or high-severity problems such as exposed credentials or injection vulnerabilities.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 320 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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-review 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 yesterday.

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.

What it actually says

代码审查 (Code Review)

对未提交的更改进行全面的安全和质量审查:

  1. 获取更改的文件:git diff --name-only HEAD

  2. 对每个更改的文件,检查:

安全问题 (CRITICAL - 严重):

  • 硬编码的凭证、API 密钥、令牌
  • SQL 注入漏洞
  • XSS 漏洞
  • 缺少输入验证
  • 不安全的依赖
  • 路径遍历风险

代码质量 (HIGH - 高):

  • 函数 > 50 行
  • 文件 > 800 行
  • 嵌套深度 > 4 层
  • 缺少错误处理
  • console.log 语句
  • TODO/FIXME 注释
  • 公共 API 缺少 JSDoc

最佳实践 (MEDIUM - 中):

  • 变异模式 (Mutation patterns) (建议使用不可变模式)
  • 代码/注释中的 Emoji 使用
  • 新代码缺少测试
  • 无障碍问题 (a11y)
  1. 生成报告包含:

    • 严重程度: CRITICAL (严重), HIGH (高), MEDIUM (中), LOW (低)
    • 文件位置和行号
    • 问题描述
    • 建议的修复
  2. 如果发现 CRITICAL 或 HIGH 问题,阻止提交

绝不批准带有安全漏洞的代码!

What this file has done since we first saw it

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.

code-review is a command published in the GitHub repository cfrs2005/claude-init (1,365 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 320 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
