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

Use it in TypingMind

Enable Php Tpl 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 Tpl 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 Tpl 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 模板注入/SSTI 审计(php-tpl-audit)

分析 PHP 项目源码,识别模板注入(SSTI)与危险表达式执行风险:用户可控内容影响模板选择、渲染表达式解析或转为可执行代码。

分级与编号

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

TPL Sink(必做)

模板相关渲染/执行点:

  • Twig:
    • Environment->load($templateName) / createTemplate($name) / render($template)
    • |raw 或关闭自动转义策略(必须有证据点)
  • Laravel Blade(Illuminate/View,PHP 原生常见):
    • view($templateName, $data) / View::make($templateName, $data)
    • Illuminate\View\Factory->make($template) / 渲染入口 $engine->render({value})
    • 当模板可控时:Blade raw 输出({!! !!})与 @php 指令属于高危执行链(必须用证据点落到渲染/编译入口)
  • Smarty:
    • Smarty->fetch($template) / display($template)
  • 自定义模板引擎:
    • eval()、preg_replace('/e')、create_function 等被用于模板表达式
    • call_user_func / call_user_func_array 参数来自用户输入(可能触发表达式)

可控性(必做)

必须输出:

  • 用户输入如何进入“模板名/模板片段/表达式字符串”
  • 是否存在严格的白名单模板名映射
  • 是否存在沙箱/表达式限制

tracer 触发条件(必做)

  • 模板选择/表达式构造跨多个函数或经过字符串拼接

证据引用(强制:来自 php-route-tracer)

每条模板注入/SSTI 疑似漏洞必须逐项引用 trace 输出中 ## 9) Sink Evidence Type Checklist 的 TPL 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_TPL_ENGINE_RENDER_OR_PARSE_ENTRY:模板引擎渲染/表达式解析点位置证据(load/createTemplate/fetch/render 或等价入口)
  2. EVID_TPL_TEMPLATE_OR_EXPR_CONTROL:模板名或表达式是否可控证据(来自路由参数到模板构造变量的映射)
  3. EVID_TPL_EXEC_CHAIN_ENTRY:执行链入口证据(表达式求值/编译/执行:如 raw/disable escape、eval/use of call_user_func 等)

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。

报告输出

输出到:

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

条目必须包含:数据流链、可利用前置条件、可执行 PoC 框架、修复建议与搜索语句。

Why use Php Tpl Audit on TypingMind?

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

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

Which AI models can use Php Tpl 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 Tpl Audit?

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

Is the Php Tpl 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.
