  • 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 0xShe on GitHub. Read the source before you install it.

Installation

Install the Php Xss Audit 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/0xShe/PHP-Code-Audit-Skill/tree/main/php-xss-audit
  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/0xShe/PHP-Code-Audit-Skill.git /tmp/PHP-Code-Audit-Skill
mkdir -p .claude/skills
cp -r /tmp/PHP-Code-Audit-Skill/php-xss-audit .claude/skills/php-xss-audit
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Php Xss Audit 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 Php Xss Audit 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 Php Xss Audit 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.

PHP XSS 审计(php-xss-audit)

分析 PHP 项目源码,识别跨站脚本(XSS):用户输入进入输出上下文且未做正确转义/编码,或框架禁用了自动转义导致表达式执行/HTML 注入。

分级与编号

  • 详见:shared/SEVERITY_RATING.md
  • 漏洞编号:{C/H/M/L}-XSS-{序号}

XSS Sink(必做)

识别以下输出点:

  • 原生输出:echo/print/printf/<?= ?>(输出变量到响应)
  • 字符串拼接到响应:header() / setcookie()(若包含可控内容)
  • 模板渲染:
    • Twig:{{ }}(转义)与 {% autoescape false %} / |raw 风险点
    • Smarty:fetch/display 与不安全变量输出
    • Blade 类:{!! !!}(不转义输出)
  • 动态脚本/事件属性:输出到 on* 属性、<script> 内、URL 参数

逃逸/防护检查(必做)

对每条疑似链必须分析:

  • 是否存在 htmlspecialchars/htmlentities 或框架自动转义
  • 是否存在上下文编码(HTML、属性、JS、URL)
  • 是否禁用了转义(raw/raw filter/unescaped output)

tracer 触发条件(必做)

  • 用户输入经历多层处理、拼接成 HTML 片段
  • 存在分支:某分支转义,另一分支不转义
  • 输出点在模板层,输入在 controller 层

报告输出

输出到:

{output_path}/vuln_audit/xss_{timestamp}.md

漏洞条目模板(强制)

与 php-sql-audit 基本一致,但在数据流链里必须明确:

  • 输出上下文:HTML body/attribute/script/URL 参数/模板片段
  • 具体转义函数或转义关闭点的位置与证据
  • PoC 必须包含可执行 XSS payload,并区分需要的编码方式

证据引用(强制:来自 php-route-tracer)

每条 XSS 疑似漏洞必须逐项引用 trace 输出中 ## 9) Sink Evidence Type Checklist 的 XSS 行对应证据要点(允许状态为待验证,但证据引用必须存在):

  1. EVID_XSS_OUTPUT_POINT:响应输出点位置证据(echo/模板输出/<script>或属性/URL 上下文)
  2. EVID_XSS_USER_INPUT_INTO_OUTPUT:用户输入进入输出的证据
  3. EVID_XSS_ESCAPE_OR_RAW_CONTROL:转义/禁用转义证据(htmlspecialchars 等或 raw/raw 模式证据)

tracer 证据缺失处理(强制)

  • 若无法定位上述 1~3 任一关键证据要点:该漏洞状态只能标记为 ⚠️待验证,不得直接给出 ✅已确认可利用。

Why use Php Xss Audit on TypingMind?

Because you install it once and use it with any model. Php Xss Audit 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 Php Xss Audit in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/0xShe/PHP-Code-Audit-Skill/tree/main/php-xss-audit. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Php Xss Audit?

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 Php Xss Audit?

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

Is the Php Xss Audit AI skill free?

It is published on GitHub by 0xShe. Check the repository for licensing terms. 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.
