怎么装How to install

NPM · Node.js

npm install -g memlab

选择与你的环境对应的方式。命令来自项目文档，未运行实测。Choose the option for your environment. Commands come from project documentation and have not been run-tested.

限制与风险Limits and risk

以下要求与风险来自文档静态检查，未执行项目代码；扫描没有命中，不代表使用安全。Risk here is evidence, not an alarm. These findings come from static scanning of the docs; we never execute a project’s code.

静态扫描STATIC SCAN

01控制浏览器Controls a browserreadme

- **Browser memory leak detection** - Write test scenarios with the Puppeteer

02控制浏览器Controls a browserplugins/memlab/skills/memlab-capture-heap-snapshots/SKILL.md
```
**From Puppeteer or Playwright test code** (Chromium only): use a CDP session.
```

静态扫描发现一个中等风险：该工具能控制浏览器（通过 Puppeteer 编写测试场景）。使用时请注意，它可能会自动操作浏览器，确保在受控环境中使用。A static scan flagged a medium risk: Memlab controls a browser via Puppeteer for memory leak detection. This is expected behavior, but review the code if you have security concerns.
