Skill 文档

SEO Analyzer Skill

基于 Google 官方文档的 SEO 自动检测工具。自动分析网址的技术 SEO、内容元数据、性能体验和链接结构，输出符合 Google 最佳实践的检测报告。

使用方法

自动模式 (推荐)

只需告诉 agent 检查某个 URL，skill 会自动完成所有工作：

python skills/seo-analyzer/scripts/seo_analyzer.py --auto <url>

Skill 会自动:

  1. 检查 agent-browser 是否已安装
  2. 如果已安装，调用 agent-browser 获取页面内容
  3. 执行完整的 SEO 检查
  4. 生成详细的检测报告

手动模式

如果 agent-browser 未安装，可以使用手动模式：

# 方式1: 从文件分析
python skills/seo-analyzer/scripts/seo_analyzer.py page.html <url>

# 方式2: 从 stdin 读取 (需要先手动获取 HTML)
agent-browser get source > page.html
python seo_analyzer.py page.html <url>

对于 Agent 的调用方式

当用户请求分析某个 URL 时：

# 使用自动模式
python skills/seo-analyzer/scripts/seo_analyzer.py --auto https://example.com

Agent 内部会：

  1. 调用 check_agent_browser_available() 检查 agent-browser
  2. 如果可用，调用 fetch_page_with_agent_browser(url) 获取页面
  3. 如果不可用，提示用户安装 agent-browser
  4. 调用 analyze_page() 执行 SEO 分析
  5. 输出格式化报告

Alternative – save to file first:

# Step 1: Open page
agent-browser open <url> --timeout 30000

# Step 2: Save HTML to file
agent-browser get source > /tmp/page.html

# Step 3: Run analysis
python skills/seo-analyzer/scripts/seo_analyzer.py /tmp/page.html <url>

Command-line Options

# Analyze HTML file
python skills/seo-analyzer/scripts/seo_analyzer.py page.html https://example.com

# Read from stdin (pipe from agent-browser)
agent-browser get source | python skills/seo_analyzer.py - https://example.com

# Output in JSON format (for programmatic use)
python seo_analyzer.py page.html https://example.com --json

Workflow

  1. Crawl the URL – Use agent-browser to load the page and capture HTML
  2. Extract page content – Use agent-browser get source to get HTML
  3. Run SEO checks – Pass HTML to seo_analyzer.py for evaluation
  4. Generate report – Output findings with severity levels and recommendations

For Agents: How to Analyze a URL

When asked to analyze a website’s SEO, follow these steps:

# 1. Open the URL with agent-browser
agent-browser open <target_url> --timeout 30000

# 2. Get the HTML source from the browser
agent-browser get source > /tmp/target_page.html

# 3. Run the SEO analyzer
python skills/seo-analyzer/scripts/seo_analyzer.py /tmp/target_page.html <target_url>

Or as a single command:

agent-browser open <target_url> --timeout 30000 && agent-browser get source | python skills/seo-analyzer/scripts/seo_analyzer.py - <target_url>

agent-browser open –timeout 30000


### Step 2: Extract the page HTML
After the page loads, get the HTML content:

agent-browser get source

Or use get text to extract visible content:

agent-browser get text “body”


### Step 3: Save HTML to file and run analysis
Write the HTML to a file, then run the analyzer:
```bash
# Save HTML content to a file
echo "<html>...</html>" > /tmp/page.html

# Run the SEO analyzer
python skills/seo-analyzer/scripts/seo_analyzer.py /tmp/page.html <url>

Integrated workflow (recommended)

Use stdin to pass HTML directly:

agent-browser get source | python skills/seo-analyzer/scripts/seo_analyzer.py - <url>

Alternative: Analyze existing HTML file

If you already have HTML content saved:

python skills/seo-analyzer/scripts/seo_analyzer.py /path/to/page.html https://example.com/page
