browser

browser is a skill for Claude Code from nullskymc/Aurevoy. It costs 63 tokens per session (838 once invoked), scanned A, original, MIT.

A browser-automation skill that controls a web browser to load pages, interact with forms and buttons, inspect page structure, and capture screenshots.

In plain words
What is it for?
Use it to check rendered interfaces, test end-to-end user flows, extract dynamic content, debug front-end errors, and save screenshots.
Why use it?
It lets an agent test what a user actually sees and handles pages whose content is created by JavaScript. It can also expose browser console errors and network requests.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

browser scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Browser 浏览器自动化技能

你启用了浏览器自动化能力。通过 Playwright MCP Server,你可以操控无头浏览器来:

可用能力

页面导航与交互

  • 打开任意 URL 并等待页面加载完成
  • 点击按钮、填写表单、触发事件
  • 页面滚动、切换标签页
  • 等待特定元素出现或网络空闲

信息提取

  • 截图:捕获页面可视区域的 PNG 截图
  • DOM 摘要:获取页面结构的可访问性树(accessibility tree),比原始 HTML 更精简易读
  • 控制台输出:抓取浏览器控制台的错误和警告信息
  • 网络请求:监控页面发出的 API 请求和响应

测试与验证

  • 验证页面功能是否正常
  • 检查 UI 渲染效果
  • 排查前端错误
  • 端到端工作流测试

使用指南

何时使用浏览器

  • 需要查看页面实际渲染效果时
  • 需要抓取 JavaScript 动态渲染的内容(web_fetch 只能获取静态 HTML/文本)
  • 需要模拟用户操作(登录、搜索、提交表单)
  • 需要调试前端错误
  • 需要截图作为产物交付

何时不用浏览器

  • 仅获取静态页面正文 → 用 web_fetch(更快更轻量)
  • 仅搜索信息 → 用 web_search
  • 仅读取本地文件 → 用 read_file

操作原则

  1. 先轻后重:优先用 web_fetch 获取内容,确认需要 JS 渲染再用浏览器
  2. 快速收窄:打开页面后先看 DOM 摘要定位关键元素,再精确交互
  3. 保存证据:重要页面状态用截图保存为 artifact
  4. 处理错误:检查控制台输出中的错误信息
  5. 超时处理:页面加载慢时设置合理的超时时间

首次配置

浏览器能力通过 Playwright MCP Server 提供。需要先安装和配置:

# 安装 Playwright MCP Server
npm install -g @anthropic/mcp-server-playwright

# 在 Aurevoy 设置中配置 MCP Server:
# command: npx
# args: ["-y", "@anthropic/mcp-server-playwright"]

或者在 AUREVOY_MCP_SERVERS_JSON 环境变量中配置:

{
  "mcpServers": {
    "playwright": {
      "command": "npx",
      "args": ["-y", "@anthropic/mcp-server-playwright"],
      "enabled": true
    }
  }
}

配置后重启 Aurevoy,浏览器相关工具会自动注册。

输出格式

浏览器操作后请呈现:

## 浏览器操作结果

### 页面: <URL>
### 状态: <加载状态>

### DOM 摘要
<关键元素和结构>

### 截图
<截图已保存为 artifact>

### 控制台输出
<错误/警告信息>

### 分析
<基于以上信息的分析>

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
