browser-use is a Claude Code skill for AI-driven browser automation using the browser-use library, where an LLM interprets pages and decides actions.

About

browser-use is a Claude Code skill for AI-driven browser automation built on the browser-use Python library, where an LLM reads pages and decides the next action instead of following a fixed script. A developer uses it for complex or dynamic browser tasks that need intelligent decisions, such as extracting structured data from a site. It documents LLM configuration, Chrome sessions, login-state persistence, and token-reduction settings. Documentation is primarily in Chinese.

  • AI-driven browser automation using the browser-use library, where an LLM understands pages and decides actions
  • Covers custom LLM config (ChatAnthropic/ChatOpenAI), Chrome sessions, login-state reuse, and structured output
  • Includes token-optimization tactics like use_vision=False and message compaction

What it does

Automate complex, dynamic browser tasks by letting an LLM understand pages and decide actions, and extract structured data.

Who is it for?

Complex or dynamic browser interactions needing intelligent decisions and structured-data extraction

Skip if: Simple stable pages where a scripted Playwright flow is cheaper

When should I use this skill?

You need a browser task that adapts to page changes and needs the model to decide actions

browser-use 智能浏览器自动化

概述

browser-use 是一个 AI 驱动的浏览器自动化工具,它使用 LLM 来:

  • 理解网页内容
  • 智能决策下一步操作
  • 自动完成任务

与 Playwright 的区别:

特性Playwrightbrowser-use
控制方式预编程脚本AI智能决策
适应性页面变化需重写自动适应
Token消耗较低但需调试智能精简
复杂交互需精确选择器自然语言描述
维护成本

⚠️ 资源清理原则(强制)

所有涉及浏览器的 cron 任务完成后,必须自动关闭 Chrome 进程!

import asyncio
from browser_use import Agent

async def main():
    agent = Agent(task="...", llm=llm)
    result = await agent.run()

    # ⚠️ 任务结束后必须显式关闭浏览器
    if hasattr(agent, 'browser') and agent.browser:
        await agent.browser.close()

    # ⚠️ 推荐在脚本结束时强制清理残留进程
    import subprocess
    subprocess.run(['pkill', '-f', 'chrome'], capture_output=True)

    return result

原因: 避免内存泄漏和资源占用,防止 Gateway CPU 100% 过载

安装状态

✅ 已安装:

  • browser-use 0.11.11
  • browser-use-sdk 2.0.15

快速开始

基本用法

import asyncio
from browser_use import Agent
from langchain_openai import ChatOpenAI

async def main():
    agent = Agent(
        task="打开 polymarket.com,查看 Fed 利率市场",
        llm=ChatOpenAI(model="gpt-4o"),
    )
    result = await agent.run()
    print(result)

asyncio.run(main())

使用自定义 LLM(推荐配置)

⚠️ 重要:your-provider API 是 Anthropic 格式,不是 OpenAI 格式!必须使用 ChatAnthropic

from browser_use.llm.anthropic.chat import ChatAnthropic

# your-provider API(Anthropic 兼容)✅ 推荐
llm = ChatAnthropic(
    model="claude-sonnet-4-6",
    base_url="https://your-anthropic-proxy.example.com",  # 注意:不加 /v1
    api_key="your-api-key",  # 或从 pass show api/your-provider 获取
)

agent = Agent(
    task="你的任务",
    llm=llm,
)
# ❌ 错误用法:不要用 ChatOpenAI + your-provider
# from browser_use.llm.openai.chat import ChatOpenAI  # 这个不行!your-provider 不支持 OpenAI 格式
# 如果使用 OpenAI 兼容 API(如 Provider-B),用 ChatOpenAI:
from browser_use.llm.openai.chat import ChatOpenAI
llm = ChatOpenAI(
    model="gpt-4o",
    base_url="https://ai.9w7.cn/v1",
    api_key="your-api-key",
)

使用 Chrome 浏览器

from browser_use import Agent, BrowserProfile, BrowserSession

# 配置使用 Chrome
profile = BrowserProfile(
    executable_path="/usr/bin/google-chrome-stable",
    headless=True,
    disable_security=True,
)
session = BrowserSession(browser_profile=profile)

agent = Agent(
    task="任务描述",
    llm=llm,
    browser_session=session,
)

保存/加载登录态

# 保存登录态
await browser_context.save_storage_state(path="polymarket_auth.json")

# 加载登录态
context = BrowserContextConfig(
    storage_state="polymarket_auth.json"
)

常用配置

最小化 Token 消耗

agent = Agent(
    task="任务",
    llm=llm,
    use_vision=False,  # 禁用视觉,减少token
    max_actions_per_step=3,  # 限制每步操作数
    message_compaction=True,  # 消息压缩
)

调试模式

agent = Agent(
    task="任务",
    llm=llm,
    headless=False,  # 显示浏览器
    slow_mo=1000,  # 慢放,每步延迟1秒
    save_conversation_path="debug_log/",  # 保存日志
)

提取结构化数据

from pydantic import BaseModel

class MarketData(BaseModel):
    question: str
    yes_price: float
    no_price: float

agent = Agent(
    task="获取 Polymarket Fed 利率市场数据",
    llm=llm,
    output_model_schema=MarketData,
)
result = await agent.run()
# result 将是 MarketData 类型

Polymarket 集成

查看市场

agent = Agent(
    task="""
    1. 打开 https://polymarket.com/event/fed-decision-in-march-885
    2. 提取以下信息:
       - 市场问题
       - Yes 价格
       - No 价格
       - 交易量
    3. 返回 JSON 格式数据
    """,
    llm=llm,
)

执行交易

agent = Agent(
    task="""
    1. 打开 Polymarket
    2. 连接钱包(如果需要)
    3. 导航到 Fed 利率市场
    4. 买入 $0.60 的 No(价格 ≥ 0.85)
    5. 确认交易
    """,
    llm=llm,
    sensitive_data={
        "wallet_address": "0x...",
    }
)

最佳实践

1. 任务描述要清晰

# 好 ✅
task="打开 polymarket.com,找到 Fed 利率市场,提取 Yes/No 价格"

# 差 ❌
task="帮我看看那个市场"

2. 使用结构化输出

from pydantic import BaseModel

class TradingResult(BaseModel):
    success: bool
    market: str
    action: str  # "buy_yes", "buy_no"
    amount: float
    price: float
    tx_hash: str | None

agent = Agent(
    task="执行交易...",
    output_model_schema=TradingResult,
)

3. 错误处理

try:
    result = await agent.run()
except Exception as e:
    print(f"任务失败: {e}")
    # 可以使用 browser tool 作为后备

4. 复用登录态

# 第一次登录后保存
# 后续直接加载,避免重复登录

browser_context = BrowserContextConfig(
    storage_state="~/.playwright-data/polymarket/auth.json"
)

Token 消耗优化

对比(相同任务)

工具平均 Token原因
browser tool~5000-10000每次快照全页面
Playwright~1000-2000需多次调试
browser-use~2000-4000AI精简决策

优化技巧

1. 禁用视觉use_vision=False 2. 限制历史max_history_items=10 3. 压缩消息message_compaction=True 4. 减少步骤max_actions_per_step=3 5. 使用 Flash 模式flash_mode=True(快速模式)

from pydantic import BaseModel
import os

class MarketInfo(BaseModel):
    question: str
    yes_price: float
    no_price: float
    volume: str

async def check_polymarket():
    # 使用本地 LLM API
    llm = ChatOpenAI(
        model="claude-3-5-sonnet-20241022",
        base_url="https://your-anthropic-proxy.example.com",
        api_key=os.environ.get("XSC_API_KEY"),
    )
    
    agent = Agent(
        task="""
        访问 Polymarket Fed 利率市场:
        https://polymarket.com/event/fed-decision-in-march-885
        
        提取并返回:
        - 市场问题
        - Yes 价格(0-1)
        - No 价格(0-1)
        - 24h 交易量
        """,
        llm=llm,
        output_model_schema=MarketInfo,
        use_vision=False,
        max_actions_per_step=5,
    )
    
    result = await agent.run()
    return result

if __name__ == "__main__":
    asyncio.run(check_polymarket())
