About code-audit
A source-code security audit skill for white-box reviews and PR diffs where repository access is available. Its workflow combines threat modeling, SAST, and manual validation, with findings documented alongside evidence and remediation advice.
Key features
- 01Define code scope and threat boundaries
- 02Run SAST scans such as Semgrep
- 03Manually validate reachability and exploitability
- 04Review authorization, injection, and cryptography
- 05Document evidence and remediation advice
Use cases
- 01Review PRs or code diffs
- 02Audit security logic in owned services
- 03Validate automated scan findings
- 04Check for authorization flaws, injection, or hardcoded keys

From the project READMESource Code Security Audit
ACTION REQUIRED（读完后立刻执行）
NOW: 读取../field-journal/precedent-pentest.md或代码审计授权NOW: 确认有源码/仓库访问（无源码二进制 → 转 RE skill）NOW: 明确语言栈与范围（目录/服务/PR diff）NEXT: tool-index；semgrep 等ACT: 威胁建模草图 → 自动扫描 → 人工验证
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 |

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？
