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.

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 | $0.00044 | $0.00430 |
| Opus 5 | $0.00022 | $0.00215 |
| Sonnet 5 | $0.00009 | $0.00086 |
| Haiku 4.5 | $0.00004 | $0.00043 |
Grade A, and why
redteam-recon-intake 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 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.
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.

What it actually says
Recon Intake
Domain
裸域名/URL/IP 首次进入安全评估时的侦察入口。 负责从零建立目标资产画像(recon_profile)，为后续 CVE Lookup 和攻击路径分配提供事实依据。
阶段顺序：
- DNS 解析 + 存活探测
- 端口扫描 + 服务指纹
- 子域枚举
- Web 目录/敏感文件探测
- WAF/CDN 识别
- 技术栈指纹(CMS/框架/中间件版本)
Boundaries
- 不执行任何主动漏洞利用
- 不发送破坏性请求(DELETE/DROP/shutdown)
- 仅探测当前目标，不自动扩展到任务中未出现的关联域名/IP
- 不进行暴力破解或密码喷洒
- 不绕过速率限制(如被限速则降速或暂停)
- 侦察深度止于信息收集，不进入漏洞验证阶段
Pivot Hints
- WAF/CDN 阻断直连 → 尝试历史 DNS、邮件头、证书搜索获取真实 IP
- 子域枚举受限 → 证书透明度日志、DNS 区域传送、关联域反查
- 目录扫描被封 → 降速、换 User-Agent、使用自定义字典
- 端口全部过滤 → 检查 IPv6、尝试常见高端口、确认目标存活
- 信息收集饱和 → 整理已有信息，输出 recon_profile 并推进到下一阶段
Exit Evidence
- Required: recon_profile, port_scan_result, service_fingerprint
- min_attempts: 4
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 · 42 lines · 44 tokens per session scan A 533144c15380
redteam-recon-intake is a skill published in the GitHub repository Netw0rkNoob/VulnClaw (3,299 stars, last pushed 6d ago), licensed MIT. It adds 44 tokens to every session and 430 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
