code-audit SKILL.md skillA

code-audit from coco-research/coco is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add coco-research/coco/code-audit@git:20260914.480426e

Pins git:20260914.480426e in mdr.lock. Pin the fingerprint instead.

Use for authorized source-code security review and SAST workflows including Semgrep, CodeQL patterns, dangerous API hunting, and fix verification.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Source Code Security Audit

## 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

```text
□ 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

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

### 3. 人工验证（MUST）

```text
□ 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

```text
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 |

How to install

The exact contents, by fingerprint

mdr add coco-research/coco/code-audit@sha256:b710916dba76f21e

The line at the top of this page pins the label git:20260914.480426e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
