What does the Code Audit skill do?

Source Code Security Audit It is listed under Security on SkillMD.

Is Code Audit safe to use?

This skill has not completed SkillMD's automated safety review yet. Independent scanners report: SkillSpector: PASS, Skill Scanner: PASS. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Code Audit?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Code Audit free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

When to Use

Reviewing a codebase for security defects with static analysis.
Verifying that a vulnerability fix actually removes the flawed pattern.

适用场景

白盒审计、PR/差分安全审查
Semgrep / CodeQL / Bandit / gosec 等 SAST
危险 API、注入点、鉴权缺失、加密误用
与 supply-chain-security/ 分工：本 skill 偏自有代码逻辑，供应链偏依赖与管道

工作流

1. 范围与威胁模型

□ 信任边界：用户输入、文件、反序列化、SSRF、鉴权中间件
□ 高价值资产：鉴权、支付、管理端、密钥处理

2. 自动扫描

semgrep --config auto .
# 或项目规则包
semgrep --config p/owasp-top-ten .

3. 人工验证（MUST）

□ 每个 SAST 命中：可达性？可利用性？误报？
□ 鉴权：IDOR/越权、缺校验、错误的多租户隔离
□ 注入：SQL/命令/模板/LDAP
□ 加密：硬编码密钥、ECB、自定义 crypto

4. 产出

Finding：位置 + 数据流 + PoC + 修复建议
可选 ATT&CK / CWE 编号

工具链

工具	语言/场景
Semgrep	多语言快速规则
CodeQL	深数据流（GitHub）
Bandit	Python
gosec / staticcheck	Go
SpotBugs / FindSecBugs	Java

参考

references/sast-review-checklist.md
../supply-chain-security/ ../api-security/ ../llm-security/（Agent 代码）

路由上下文

上游: MASTER R26
角色: ops/role-map.md cae
下游: 依赖漏洞 → supply-chain；运行时验证 → pentest-tools

任务完成自检

是否人工验证而非只贴扫描器输出？
是否含修复建议？
是否限定在授权仓库范围？
Checklist？

Limitations

Static analysis produces false positives; manual triage is required.
Coverage depends on language support of the chosen SAST engine.
