code-audit

Helps your agent review code for security flaws. It looks for dangerous patterns and verifies if fixes have been applied correctly.

What it does

This tool helps find security flaws in programming code. It scans the code for dangerous patterns and suggests how to fix them.

When to use it

  • ✓When reviewing code for security defects using static analysis.
  • ✓When verifying that a vulnerability fix actually removes the flawed pattern.
  • ✓When looking for potentially dangerous code patterns.

Example of what to ask your AI

“Scan my Python code for security vulnerabilities.”

Ready-to-paste message

Use this skill to help me: https://github.com/sickn33/agentic-awesome-skills/blob/main/plugins/agentic-awesome-skills-claude/skills/code-audit/SKILL.md Read the SKILL.md file at that link and follow its instructions for my task.
How it works

The tool uses programs like Semgrep and CodeQL to analyze the code automatically. Then, you need to manually review the results to confirm issues and suggest fixes.

Installation

Easiest way: copy the skill link and paste it into Claude, ChatGPT or Cursor asking it to follow the instructions.

In the terminal (Claude Code, Codex, Cursor), in your project folder:

npx skills add sickn33/agentic-awesome-skills --skill code-audit

Or download just the file:

curl -L https://raw.githubusercontent.com/sickn33/agentic-awesome-skills/main/plugins/agentic-awesome-skills-claude/skills/code-audit/SKILL.md -o SKILL.md

Source Code Security Audit

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

  • ../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.

FAQ

What is static analysis?

It's a way to analyze code without running it, looking for errors or security issues.

What is a false positive?

It's when the tool flags an issue that isn't actually an error or a security risk.

What programming languages are supported?

Support depends on the analysis tools used, but it includes popular languages like Python, Java, and Go.
