About the project

VulnClaw is an AI-driven command-line penetration-testing agent that turns natural-language instructions into an automated workflow for reconnaissance, vulnerability discovery, exploitation, and report generation. It is intended for authorized penetration tests, CTF competitions, security teaching, and red-team exercises, using LLMs and MCP tools. The catalogue contains its specialized skills for security-testing tasks.

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

secknowledge-skill 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 10d ago.

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.

Web 和 AI 安全测试知识库

知识源: WooYun 88,636 漏洞 × 先知 5,600+ 文档 × GAARM 150 AI 风险 × OWASP 架构: SKILL.md(路由)→ references/(按场景加载)

VulnClaw 集成说明

  • 本 Skill 集成自 Pa55w0rd/secknowledge-skill,在 VulnClaw 中作为 secknowledge-skill specialized skill 使用;上游声明为 MIT License。
  • CTF/SRC 场景先加载 references/vulnclaw-ctf-src-routing.md 判断资料入口,再按漏洞类型加载 web-*ai-*testing-methodology.mdgaarm-risk-matrix.md
  • 与 VulnClaw 现有技能协同:CTF 单题技巧优先结合 ctf-web/ctf-crypto/ctf-misc,SRC 和实战漏洞挖掘优先使用本 Skill 的方法论、案例映射、风险矩阵和证据约束。
  • 输出时保留上游的授权边界、引用标注和"假设/确认"区分;未能从 reference 佐证的 payload、CVE、GAARM/OWASP 编号必须明确标注为未核对。

触发条件

触发条件(AND 组合)

  1. 用户意图是执行安全测试(渗透/挖洞/利用/审计) — 非讨论/学习
  2. 提供了具体目标:URL、接口、代码片段、模型/Agent 架构、MCP 配置 — 非抽象问题
  3. 任务涉及以下领域之一
    • Web: SQL 注入/XSS/命令执行/越权/文件上传/SSRF/反序列化/XXE/GraphQL/HTTP 走私
    • AI: Prompt 注入/越狱/MCP 投毒/Agent 滥用/RAG 投毒/沙箱逃逸/模型窃取
    • 绕过: WAF/内容过滤/Guard Rails 绕过

不触发(任一命中即路由到他处):

  • 概念讲解:"什么是…"、"…原理"、"…怎么防御" → 普通问答
  • 非安全代码审查:"review 代码质量"、"优化性能" → 普通 code review
  • 业务 bug:语法错误、空指针、业务逻辑错误(非安全逻辑)→ 普通 debug
  • 深度白盒代码审计(Source-Sink 污点传播、AST 分析)→ code-audit-skill
  • 查 CVE 文档、工具文档 → WebSearch/Context7

歧义处理:目标和意图不明时,先问:"目标是什么?你希望做渗透测试 / 代码审计 / 还是了解概念?"

行为准则(整个会话有效,不因对话长度放松)

  1. 所有 Payload/CVE 编号/风险编号必须引用 reference 文件的具体章节 — 每次输出前自检。未在 reference 中的一律标注 "UNABLE TO CITE",禁止编造。
  2. 区分"漏洞假设"与"漏洞确认" — 基于方法论推断的潜在风险 → 标注 假设(需验证);有明确证据的 → 标注 已确认(证据: …)。禁止混淆。
  3. 授权边界 — 任何利用步骤输出前必须确认是 CTF/授权渗透/本人环境。无授权上下文只输出分析,不输出可直接武器化的完整 Payload。

幻觉防护与来源引用

内容类型 正确输出 禁止输出
CVE 编号 引用具体 reference 文件和章节,或标 "UNABLE TO CITE — 建议 WebSearch 核实" 编造 CVE-YYYY-NNNN
Payload references/web-*.mdreferences/ai-*.md 内 payload 章节引用 凭印象写 payload
GAARM 风险编号 引用 references/gaarm-risk-matrix.md 自造编号
OWASP 条目 LLM01-10 / ASI01-10 / WSTG-* 引用 testing-methodology.md §10.x 改写编号含义
工具/命令 仅使用在 reference 中出现过的,或明确标注 "通用命令(未在 reference 中核对)" 伪造工具参数
无检索结果 "UNABLE TO ASSESS:reference 未覆盖此场景,建议 WebSearch" 凭经验推测作为结论

What ships with it

40 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
