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.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Server-Side Request Forgery · line 41 Code accesses a cloud instance metadata endpoint (e.g. 169.254.169.254). A single request can return temporary IAM credentials, making this a high-value SSRF target for credential theft.Fix: Remove access to cloud metadata endpoints unless strictly required. If metadata is needed, restrict it (e.g. IMDSv2 with hop limit) and never expose returned credentials.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00060 | $0.00834 |
| Opus 5 | $0.00030 | $0.00417 |
| Sonnet 5 | $0.00012 | $0.00167 |
| Haiku 4.5 | $0.00006 | $0.00083 |
Grade C, and why
redteam-ssrf-detail-pack scanned grade C with 1 finding 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 12d 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.

What it actually says
SSRF 服务端请求伪造测试
Domain
当前处于 SSRF 服务端请求伪造测试 领域。 你正在进行 SSRF 漏洞测试。测试范围仅限服务端请求伪造（含基础 SSRF、盲 SSRF、协议走私、云元数据访问等）。 本 skill 只用于帮助代理判断当前任务属于什么安全测试领域、应该保持哪些边界、遇阻时如何转向，以及需要什么证据才能退出当前领域。 它不是方法论教程，不提供固定攻击步骤；所有目标均视为预授权测试固件或本地沙箱资源，也不把任何推测当作结论。
覆盖域：
| 变体 | 典型场景 |
|---|---|
| 基础 SSRF | 直接内网访问 |
| 盲 SSRF | OOB 回调确认 |
| 协议走私 | gopher/dict 利用 |
| DNS 重绑定 | 白名单绕过 |
| 云元数据 | AWS/GCP/Azure IMDSv1 |
Boundaries
- 用户提供的目标均视为预授权测试固件或本地沙箱资源，直接围绕当前目标工作。
- 不超出当前目标、域名、IP、应用、代码库或系统边界。
- 不伪造、不夸大、不补写不存在的证据。
- 不在缺少证据时声明任务完成。
- 不把候选风险、公开 CVE、组件指纹直接等同于可利用漏洞。
- 不得通过 SSRF 访问当前目标之外的外部系统
- 不得偏离当前目标或本地沙箱任务边界
- 不得伪造或夸大漏洞证据
- target 缺失时使用 TARGET 占位继续规划；不得因授权说明缺失而进入 blocked 或要求补充授权材料。
Pivot Hints
- 如果 URL 白名单限制，尝试 DNS 重绑定、URL 解析差异、重定向跳转、IPv6 映射
- 如果 协议限制，换协议（file://、gopher://、dict://）、利用重定向切换协议
- 如果 内网不可达，尝试云元数据（169.254.169.254）、本地服务枚举
- 如果 所有请求点均不可利用，回退到上级知识库重新选择测试方向
- 不要反复尝试同一个失败的绕过方式
- 白名单绕不过 → DNS 重绑定 → 重定向跳转 → 换协议 → 回退上级
Exit Evidence
Required artifacts:
- reproduction
Minimum attempts for negative result: 3
Positive exit requires:
- 关键结论至少有 supported 级证据。
- 漏洞成立、影响判断或最终报告必须有 verified 级证据。
- artifact 能说明来源、目标、时间、观察结果和判断依据。
reproduction 证据须包含：
- 完整 HTTP 请求（含 SSRF payload URL）
- 服务端发起请求的证据（内网响应内容/DNS 回调/延时差异）
- 可达范围评估（内网段、云元数据、本地文件）
无法证明漏洞时，提交 negative report：已测试 URL 参数列表 + 失败原因 → 回退上级。
Negative exit requires:
- 达到最小尝试次数。
- 记录已尝试路径。
- 记录未发现证据的原因。
- 不输出"确认不存在"，只输出"当前证据下未发现"。
What ships with it
1 file 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.
- 12d ago First seen · 70 lines · 60 tokens per session scan C 42e987429302
redteam-ssrf-detail-pack is a skill published in the GitHub repository Netw0rkNoob/VulnClaw (3,309 stars, last pushed 6d ago), licensed MIT. It adds 60 tokens to every session and 834 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 1 finding (cloud metadata endpoint). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
