Agent Browser Skill

Agent Browser Skill

Fast browser automation using accessibility tree snapshots with refs for deterministic element selection.
借助可访问性树快照和引用实现确定性元素选择的快速浏览器自动化工具。

Why Use This Over Built-in Browser Tool

为何选择它而非内置浏览器工具

Use agent-browser when:
  • Automating multi-step workflows
  • Need deterministic element selection
  • Performance is critical
  • Working with complex SPAs
  • Need session isolation
Use built-in browser tool when:
  • Need screenshots/PDFs for analysis
  • Visual inspection required
  • Browser extension integration needed
使用agent-browser的场景：
  • 自动化多步骤工作流
  • 需要确定性元素选择
  • 性能至关重要
  • 处理复杂SPA
  • 需要会话隔离
使用内置浏览器工具的场景：
  • 需要截图/PDF用于分析
  • 需要视觉检查
  • 需要浏览器扩展集成

Core Workflow

核心工作流

bash
undefined
bash

1. Navigate and snapshot

1. 导航并生成快照

agent-browser open https://example.com agent-browser snapshot -i --json
agent-browser open https://example.com agent-browser snapshot -i --json

2. Parse refs from JSON, then interact

2. 解析JSON中的引用，然后进行交互

agent-browser click @e2 agent-browser fill @e3 "text"
agent-browser click @e2 agent-browser fill @e3 "text"

3. Re-snapshot after page changes

3. 页面变化后重新生成快照

agent-browser snapshot -i --json
undefined
agent-browser snapshot -i --json
undefined

Key Commands

核心命令

Navigation

导航

bash
agent-browser open <url>
agent-browser back | forward | reload | close
bash
agent-browser open <url>
agent-browser back | forward | reload | close

Snapshot (Always use -i --json)

快照（始终使用 -i --json）

bash
agent-browser snapshot -i --json          # Interactive elements, JSON output
agent-browser snapshot -i -c -d 5 --json  # + compact, depth limit
agent-browser snapshot -s "#main" -i      # Scope to selector
bash
agent-browser snapshot -i --json          # 仅包含交互元素，JSON格式输出
agent-browser snapshot -i -c -d 5 --json  # + 紧凑格式、深度限制
agent-browser snapshot -s "#main" -i      # 限定选择器范围

Interactions (Ref-based)

交互操作（基于引用）

bash
agent-browser click @e2
agent-browser fill @e3 "text"
agent-browser type @e3 "text"
agent-browser hover @e4

agent-browser select @e6 "value"
agent-browser press "Enter"
agent-browser scroll down 500
agent-browser drag @e7 @e8

Best Practices

最佳实践

  1. Always use 
    -i
    flag     - Focus on interactive elements
  2. Always use 
    --json
     - Easier to parse
  3. Wait for stability - 
    agent-browser wait --load networkidle
  4. Save auth state - Skip login flows with 
    state save/load
  5. Use sessions - Isolate different browser contexts
  6. Use 
    --headed
    for debugging     - See what's happening
  1. 始终使用
    -i
    参数     - 仅关注可交互元素
  2. 始终使用
    --json
    参数     - 更易于解析
  3. 等待页面稳定 - 使用
    agent-browser wait --load networkidle
  4. 保存认证状态 - 通过
    state save/load
    跳过登录流程
  5. 使用会话 - 隔离不同的浏览器上下文
  6. 调试时使用
    --headed
    参数     - 可视化查看操作过程

Example: Search and Extract

示例：搜索与提取

bash
agent-browser open https://www.google.com
agent-browser snapshot -i --json
bash
agent-browser open https://www.google.com
agent-browser snapshot -i --json

AI identifies search box @e1

AI识别出搜索框@e1

agent-browser fill @e1 "AI agents" agent-browser press Enter agent-browser wait --load networkidle agent-browser snapshot -i --json
agent-browser fill @e1 "AI agents" agent-browser press Enter agent-browser wait --load networkidle agent-browser snapshot -i --json

AI identifies result refs

AI识别出结果引用

agent-browser get text @e3 --json agent-browser get attr @e4 "href" --json
undefined
agent-browser get text @e3 --json agent-browser get attr @e4 "href" --json
undefined

Example: Multi-Session Testing

示例：多会话测试

Admin session

管理员会话

agent-browser --session admin open app.com agent-browser --session admin state load admin-auth.json agent-browser --session admin snapshot -i --json
agent-browser --session admin open app.com agent-browser --session admin state load admin-auth.json agent-browser --session admin snapshot -i --json

User session (simultaneous)

用户会话（同时进行）

agent-browser --session user open app.com agent-browser --session user state load user-auth.json agent-browser --session user snapshot -i --json
