pentester: Skill for Claude Code

.agents/skills/third-party/redteam-recon-intake/SKILL.md

redteam-recon-intake is a skill for Claude Code, Codex from fb0sh/pentester. It costs 44 tokens per session (430 once invoked), scanned A, a copy of redteam-recon-intake, MIT.

An initial security-reconnaissance guide for a bare domain, URL, or IP address. It gathers facts such as DNS records, open ports, services, subdomains, web paths, protective layers, and technology versions without exploiting vulnerabilities.

In plain words
What is it for?
Use it as the first step of an authorized external security assessment to produce a target profile, port-scan results, and service fingerprints.
Why use it?
It creates a factual profile of the target before later security checks. Its boundaries help avoid destructive requests, brute force, and expanding beyond the named target.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is fb0sh/pentester's own configuration. It tells Claude Code and Codex how to work on pentester itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything pentester configures →

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

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 8d 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.

Origin

This is a copy

100% identical to redteam-recon-intake — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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:

  1. DNS 解析 + 存活探测
  2. 端口扫描 + 服务指纹
  3. 子域枚举
  4. Web 目录/敏感文件探测
  5. WAF/CDN 识别
  6. 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
Files

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.

Changes

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.
