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 | $0.00043 | $0.00801 |
| Opus 5 | $0.00022 | $0.00400 |
| Sonnet 5 | $0.00009 | $0.00160 |
| Haiku 4.5 | $0.00004 | $0.00080 |
Grade A, and why
redteam-cve-lookup 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
CVE Lookup
Domain
Recon Profile 完成后的 CVE 匹配与适用性评估阶段。 根据已收集的产品名、版本号、服务指纹，查询已知 CVE，评估其对目标的适用性。
阶段顺序：
- 从 recon_profile 提取产品/版本/服务清单
- 按产品+版本查询 CVE 数据库(NVD/CVE MCP/本地库)
- 初筛：排除明确不匹配的 CVE(产品不符/版本范围外)
- 适用性评估：结合目标指纹判断 candidate/possibly_applicable/not_applicable/patched
- 补丁状态确认：检查已部署版本是否包含修复
Trigger
recon_profile_ready
Feedback Gates
- Product Gate：recon_profile 中是否存在可识别的组件/产品名。无产品名则证据不足，回退 recon 补证。
- Version Gate：是否有版本号或可比对的指纹信息。无版本信息降低 confidence 但不阻断。
- Source Gate：CVE 来源是否可追溯(NVD/MITRE/厂商公告)。不可追溯标记 low confidence。
- Applicability Gate：是否有证据证明目标适用该 CVE。无证据标记 candidate 待验证。
- Patch Gate：是否有证据表明已修复(版本号高于修复版本/补丁已部署)。已修复标记 patched。
Boundaries
- 不执行任何漏洞利用或 PoC
- 不发送攻击性 payload 验证 CVE
- 仅查询当前目标，不自动扩展到任务中未出现的关联目标
- CVE 查询阶段只做信息匹配，不做主动验证
- 对低置信度候选不做过度推断
- 遵循最小请求原则，避免批量爬取 CVE 数据源
Pivot Hints
- 产品名不明确 → 回退 recon，尝试更精确的指纹识别(Wappalyzer/httpx tech detect)
- 版本号缺失 → 尝试从 HTTP header/error page/changelog 推断版本范围
- CVE 数据源不可用 → 降级到离线 CVE 字典或已知漏洞列表
- 候选过多(>20) → 按 CVSS 评分+影响范围排序，优先评估高危+RCE类
- 全部标记 patched → 输出 cve_patch_status artifact，退出到 evidence-based router
- 无任何候选 → 输出空 cve_candidate_list，退出到 evidence-based router
Exit Conditions
- 存在 possibly_applicable 或 candidate CVE（confidence >= medium）→ 进入 cve-validation path
- 全部 CVE 标记 not_applicable 或 patched → 退出到 evidence-based router
- 产品/版本证据不足，无法生成有效候选 → 回退 recon-intake 补证
- 无 CVE 候选（产品无已知漏洞）→ 退出到 evidence-based router
Exit Evidence
- Required: cve_candidate_list
- Optional: cve_applicability_matrix, cve_patch_status
- min_attempts: 2
Capabilities
cve_lookup -> cve_candidate_list
cve_applicability -> cve_applicability_matrix
patch_status_check -> cve_patch_status
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.

redteam-cve-lookup is a skill published in the GitHub repository Netw0rkNoob/VulnClaw (3,309 stars, last pushed 6d ago), licensed MIT. It adds 43 tokens to every session and 801 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.
