  • Markdown instructions

    A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

  • Works with any LLM

    AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

  • 7 bundled files

    Scripts, templates, and references the model can read while it works. Files are read-only and never executed.

  • Open source

    Published by Netw0rkNoob on GitHub. Read the source before you install it.

Installation

Install the Osint Recon AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

1

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

  1. Open the app and go to Plugins → Skills.
  2. Choose "Install from GitHub".
  3. Paste the skill folder URL below and confirm.
  4. Enable the skill in any chat where you want it available.
Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.
2

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills
git clone --depth 1 https://github.com/Netw0rkNoob/VulnClaw.git /tmp/VulnClaw
mkdir -p .claude/skills
cp -r /tmp/VulnClaw/vulnclaw/skills/specialized/osint-recon .claude/skills/osint-recon
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Osint Recon in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Osint Recon on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Osint Recon is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

  • Loaded only when it is needed

    The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

  • Switch models mid-chat

    Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

OSINT 开源情报收集知识库

针对信息收集/侦察/社会工程场景的实战知识库,提供四维信息收集模型(服务器信息 → 网站信息 → 域名信息 → 人员信息),以及具体的工具使用方法和数据提取技巧。

recon Skill 的区别

  • recon → 技术层面侦察(端口扫描、DNS、目录枚举)— 基础版
  • osint-recon → 全维度侦察(服务器 + 网站 + 域名 + 人员/社会工程)— 深度版

核心原则

  1. 四维度全覆盖 — 服务器/网站/域名三个维度始终执行,人员维度按条件触发
  2. 从页面提取一切可提取的信息 — 不只看 HTTP 头,还要看 HTML 内容、JS 文件、注释
  3. 先被动后主动 — 先看响应头、DNS、WHOIS(被动),再做端口扫描/目录枚举(主动)
  4. 维度完成度自检 — 每轮检查哪些维度已完成 ✅,哪些未完成 ❌,全部完成后才允许 [DONE]
  5. 外部链接即线索 — 页面上的每个外部链接都可能是信息来源
  6. 结构化输出 — 所有发现汇总为 Markdown 报告

四维信息收集模型

维度一:服务器信息

维度四:人员信息 ⚡ 条件触发

⚠️ 此维度仅在以下条件之一满足时才执行:

  • 用户命令中明确提及"社会工程/社工/人员信息/作者追踪/人物画像"等
  • 目标网站有明确作者信息(meta author、about 页面、联系方式)

不应该做社工的情况:普通企业官网无个人作者 / 用户只要求"扫描目标" / 目标是 IP/内网地址

追踪方向方法说明
作者标识提取页面 meta author、about 页面用户名、昵称、邮箱
GitHub 追踪fetch + GitHub API仓库、语言偏好、贡献记录、邮箱
社交媒体从页面提取链接 → 访问B站、微博、知乎、Twitter、LinkedIn
跨平台关联用用户名/邮箱搜索其他平台相同 ID 跨平台搜索
历史提交GitHub commits → 提交邮箱关联其他项目和身份
泄露检测GitHub 历史代码搜索.env、config、密钥泄露

First-Pass 工作流

  1. 访问目标fetch 获取首页,提取 HTTP 头 + HTML 内容
  2. 维度一:服务器信息 → 端口扫描、真实 IP、OS 指纹、中间件/数据库识别
  3. 维度二:网站信息 → Web 指纹、WAF 检测、敏感目录/源码泄露、旁站/C段
  4. 维度三:域名信息 → WHOIS、ICP 备案、子域名、DNS 记录、证书透明度
  5. 维度四(条件触发) → 提取作者信息、跨平台追踪、信息汇总
  6. 维度完成度自检 → 确认每个维度至少做过一轮检查
  7. 汇总报告 → 生成 Markdown 格式侦察报告

⭐ 常用提取代码片段

从 HTML 提取所有外部链接

python
import re
html = "..."  # fetch 获取的 HTML
links = re.findall(r'href=["\'](https?://[^"\']+)["\']', html)
for link in set(links):
    print(link)

从 HTML 提取作者信息

python
import re
# meta author
author = re.findall(r'<meta\s+name=["\']author["\']\s+content=["\']([^"\']+)["\']', html)
# about 页面链接
about_links = re.findall(r'href=["\']([^"\']*(?:about|me|contact)[^"\']*)["\']', html, re.I)

查询 crt.sh 子域名

python
import requests
domain = "example.com"
r = requests.get(f"https://crt.sh/?q=%.{domain}&output=json")
if r.status_code == 200:
    for entry in r.json():
        print(entry['name_value'])

GitHub 用户信息

python
import requests
username = "target_user"
r = requests.get(f"https://api.github.com/users/{username}")
if r.status_code == 200:
    data = r.json()
    print(f"Name: {data.get('name')}")
    print(f"Bio: {data.get('bio')}")
    print(f"Email: {data.get('email')}")
    print(f"Blog: {data.get('blog')}")
    print(f"Location: {data.get('location')}")
    print(f"Company: {data.get('company')}")

WAF 检测(响应特征法)

python
import requests
url = "https://target.com"
# 正常请求
r1 = requests.get(url)
# 触发 WAF 的请求(带攻击特征)
r2 = requests.get(url + "/?id=1' OR 1=1--")
# 对比响应
if r1.status_code != r2.status_code or len(r1.text) != len(r2.text):
    print("[!] 可能存在 WAF")
    print(f"正常状态码: {r1.status_code}, 攻击状态码: {r2.status_code}")

旁站查询(同 IP 反查域名)

python
import requests
ip = "1.2.3.4"
# 使用 chinaz API 或其他反查接口
# 也可以通过 crt.sh 查询同 IP 的证书
r = requests.get(f"https://crt.sh/?q={ip}&output=json")

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Osint Recon AI skill do?

OSINT 开源情报收集知识库 — 四维信息收集模型(服务器→网站→域名→人员),维度四(人员信息)条件触发

Why use Osint Recon on TypingMind?

Because you install it once and use it with any model. Osint Recon is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Osint Recon in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/Netw0rkNoob/VulnClaw/tree/main/vulnclaw/skills/specialized/osint-recon. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Osint Recon?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Osint Recon?

As many as you like. As long as a model supports skills, you can use Osint Recon with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Osint Recon AI skill free?

Yes. It is published on GitHub by Netw0rkNoob under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
