  • 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 Csrf 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-csrf-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-csrf-audit .claude/skills/php-csrf-audit
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Php Csrf 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 Csrf 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 Csrf 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 CSRF 审计(php-csrf-audit)

分析 PHP 项目源码中,所有可能造成状态变更的接口(POST/PUT/PATCH/DELETE,或含副作用的 GET)是否实现了 CSRF 防护(token 校验、SameSite/CORS 配合、双提交 cookie 等)。

分级与编号

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

保护点与必检内容(强制)

必须识别并输出:

  1. 状态变更入口:路由的 HTTP 方法、是否包含副作用(写数据库/更新权限/发起交易/触发任务等)
  2. CSRF token 生成:token 来源(session/cookie/random)、字段名、注入到表单或请求头的方式
  3. CSRF token 校验:后端验证逻辑位置与条件(是否只校验登录用户、是否存在绕过分支)
  4. 校验绕过:是否存在“某些分支不校验”“仅校验特定 Content-Type”“只在 AJAX 时校验”等
  5. 同源/跨站辅助:SameSite、CORS/跨域设置、Referer/Origin 校验(注意:Referer/Origin 单独依赖也可能不稳)

数据流追踪要求

必须追踪至少一条链:

  • 从 token 来源(如 $_SESSION['csrf'])到前端输出
  • 再到后端的 token 接收($_POST/headers)与校验(比较/哈希校验)

报告输出

输出到:

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

漏洞条目模板(强制)

必须包含以下部分:

  • 位置证据(路由 + 校验函数/中间件位置)
  • 数据流链(token 生成 -> 前端携带 -> 后端校验)
  • 可利用前置条件(是否需要登录;攻击者能否构造页面;浏览器同站策略)
  • 验证 PoC(必须包含真实路由与请求结构;若需配合登录,给出 cookie/登录态说明)
  • 建议修复(token 校验放置、失败响应策略、字段名统一、对绕过分支加覆盖)

证据引用(强制:来自 php-route-tracer)

每条 CSRF 风险必须逐项引用 trace 中的证据点(允许状态为待验证,但证据引用必须存在):

  1. EVID_CSRF_STATE_CHANGE_HANDLER_EXEC:状态变更 handler 的执行证据(trace 的分支路径证据)
  2. EVID_CSRF_TOKEN_SOURCE:CSRF token 来源与生成证据(session/cookie/random 等)
  3. EVID_CSRF_TOKEN_RECEIVE:CSRF token 在请求中的接收/进入校验逻辑的位置证据(trace 的参数进入点/分支证据)
  4. EVID_CSRF_TOKEN_VERIFY:CSRF 校验比较/哈希判断位置证据(trace 的条件与早退证据)
  5. EVID_CSRF_BYPASS_BRANCH:绕过分支证据(如仅校验某些 Content-Type 或仅对 AJAX 校验)

tracer 证据缺失处理(强制)

  • 若 trace 契约校验失败或缺失上述 1~5 任一关键证据点:该风险只能标记为 ⚠️待验证,不得给出“已确认可利用”的断言。

Frequently asked questions

What does the Php Csrf Audit AI skill do?

Why use Php Csrf Audit on TypingMind?

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

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

Which AI models can use Php Csrf 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 Csrf Audit?

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

Is the Php Csrf 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.
