  • 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.

  • Self-contained

    Everything the model needs lives in the instructions — no extra files to sync.

  • Open source

    Published by xu-xiang on GitHub. Read the source before you install it.

Installation

Install the Security Scan 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.
    https://github.com/xu-xiang/everything-claude-code-zh/tree/main/docs/zh-CN/skills/security-scan
  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.

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/xu-xiang/everything-claude-code-zh.git /tmp/everything-claude-code-zh
mkdir -p .claude/skills
cp -r /tmp/everything-claude-code-zh/docs/zh-CN/skills/security-scan .claude/skills/security-scan
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Security Scan 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 Security Scan 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 Security Scan 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.

安全扫描技能

使用 AgentShield 审计您的 Claude Code 配置中的安全问题。

何时激活

  • 设置新的 Claude Code 项目时
  • 修改 .claude/settings.json、CLAUDE.md 或 MCP 配置后
  • 提交配置更改前
  • 加入具有现有 Claude Code 配置的新代码库时
  • 定期进行安全卫生检查时

扫描内容

文件检查项
CLAUDE.md硬编码的密钥、自动运行指令、提示词注入模式
settings.json过于宽松的允许列表、缺失的拒绝列表、危险的绕过标志
mcp.json有风险的 MCP 服务器、硬编码的环境变量密钥、npx 供应链风险
hooks/通过 ${file} 插值导致的命令注入、数据泄露、静默错误抑制
agents/*.md无限制的工具访问、提示词注入攻击面、缺失的模型规格

先决条件

必须安装 AgentShield。检查并在需要时安装:

bash
# Check if installed
npx ecc-agentshield --version

# Install globally (recommended)
npm install -g ecc-agentshield

# Or run directly via npx (no install needed)
npx ecc-agentshield scan .

使用方法

基础扫描

针对当前项目的 .claude/ 目录运行:

bash
# Scan current project
npx ecc-agentshield scan

# Scan a specific path
npx ecc-agentshield scan --path /path/to/.claude

# Scan with minimum severity filter
npx ecc-agentshield scan --min-severity medium

输出格式

bash
# Terminal output (default) — colored report with grade
npx ecc-agentshield scan

# JSON — for CI/CD integration
npx ecc-agentshield scan --format json

# Markdown — for documentation
npx ecc-agentshield scan --format markdown

# HTML — self-contained dark-theme report
npx ecc-agentshield scan --format html > security-report.html

自动修复

自动应用安全的修复(仅修复标记为可自动修复的问题):

bash
npx ecc-agentshield scan --fix

这将:

  • 用环境变量引用替换硬编码的密钥
  • 将通配符权限收紧为作用域明确的替代方案
  • 绝不修改仅限手动修复的建议

Opus 4.6 深度分析

运行对抗性的三智能体流程以进行更深入的分析:

bash
# Requires ANTHROPIC_API_KEY
export ANTHROPIC_API_KEY=your-key
npx ecc-agentshield scan --opus --stream

这将运行:

  1. 攻击者(红队) — 寻找攻击向量
  2. 防御者(蓝队) — 建议加固措施
  3. 审计员(最终裁决) — 综合双方观点

初始化安全配置

从头开始搭建一个新的安全 .claude/ 配置:

bash
npx ecc-agentshield init

创建:

  • 具有作用域权限和拒绝列表的 settings.json
  • 遵循安全最佳实践的 CLAUDE.md
  • mcp.json 占位符

GitHub Action

添加到您的 CI 流水线中:

yaml
- uses: affaan-m/agentshield@v1
  with:
    path: '.'
    min-severity: 'medium'
    fail-on-findings: true

严重性等级

等级分数含义
A90-100安全配置
B75-89轻微问题
C60-74需要注意
D40-59显著风险
F0-39严重漏洞

结果解读

关键发现(立即修复)

  • 配置文件中硬编码的 API 密钥或令牌
  • 允许列表中存在 Bash(*)(无限制的 shell 访问)
  • 钩子中通过 ${file} 插值导致的命令注入
  • 运行 shell 的 MCP 服务器

高优先级发现(生产前修复)

  • CLAUDE.md 中的自动运行指令(提示词注入向量)
  • 权限配置中缺少拒绝列表
  • 具有不必要 Bash 访问权限的代理

中优先级发现(建议修复)

  • 钩子中的静默错误抑制(2>/dev/null、|| true)
  • 缺少 PreToolUse 安全钩子
  • MCP 服务器配置中的 npx -y 自动安装

信息性发现(了解情况)

  • MCP 服务器缺少描述信息
  • 正确标记为良好实践的限制性指令

Frequently asked questions

What does the Security Scan AI skill do?

使用AgentShield扫描您的Claude代码配置(.claude/目录),以发现安全漏洞、配置错误和注入风险。检查CLAUDE.md、settings.json、MCP服务器、钩子和代理定义。

Why use Security Scan on TypingMind?

Because you install it once and use it with any model. Security Scan 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 Security Scan in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/xu-xiang/everything-claude-code-zh/tree/main/docs/zh-CN/skills/security-scan. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Security Scan?

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 Security Scan?

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

Is the Security Scan AI skill free?

Yes. It is published on GitHub by xu-xiang 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.
