  • 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 Session Cookie 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-session-cookie-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-session-cookie-audit .claude/skills/php-session-cookie-audit
Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Php Session Cookie 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 Session Cookie 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 Session Cookie 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 会话与 Cookie 安全审计(php-session-cookie-audit)

分析 PHP 项目源码中认证会话相关的安全设置与实现逻辑,重点检测:

  • session fixation
  • cookie flags 缺失(HttpOnly/Secure/SameSite)
  • JWT 校验缺陷(签名算法混淆、未校验 exp/iss/aud、弱密钥)
  • remember-me/持久登录弱点(若存在)

分级与编号

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

必检内容(强制)

  1. Session 初始化:
    • 是否在登录后 session_regenerate_id
    • 是否设置合理的超时、cookie 参数
  2. Cookie flags:
    • HttpOnly、Secure、SameSite 是否明确设置
  3. JWT:
    • decode/verify 使用的算法是否固定
    • 是否验证 exp/nbf/iss/aud
    • secret/公钥是否硬编码或读取不安全
  4. 退出/失效:
    • logout 是否真正清除 session 与 token

PoC 要求(强制)

  • 对 session fixation:给出请求序列(登录前固定 session id -> 登录后验证会话变化)
  • 对 cookie flags:说明浏览器侧可见差异与危害(并给出示例 HTTP 响应头)
  • 对 JWT:给出“签名算法/claim 校验缺失”的请求 PoC 框架(必须说明 payload 如何构造)

证据引用(强制:来自 php-route-tracer)

每条会话与 Cookie 安全疑似风险必须逐项引用 trace 输出中 ## 9) Sink Evidence Type Checklist 的 SESS 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_SESS_SESSION_INIT_REGEN:登录后是否 session_regenerate_id 等会话固定防护证据
  2. EVID_SESS_COOKIE_FLAGS:Cookie flags(HttpOnly/Secure/SameSite)设置证据
  3. EVID_SESS_JWT_VERIFY_CLAIMS:JWT 签名算法固定与 exp/nbf/iss/aud 等 claim 校验证据
  4. EVID_SESS_LOGOUT_CLEAR:logout 是否真正清除 session 与 token 的证据

tracer 证据缺失处理(强制)

  • 若 trace 契约校验失败或缺失上述 1~4 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。

报告输出

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

条目模板(强制)

必须包含:位置证据 + 数据流链(token/session -> 校验 -> 授权)+ 可利用前置条件 + PoC + 修复建议 + rg 搜索语句。

Why use Php Session Cookie Audit on TypingMind?

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

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

Which AI models can use Php Session Cookie 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 Session Cookie Audit?

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

Is the Php Session Cookie 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.
