content-extract — 上层内容解析入口(MCP 语义对齐,但不跑 MCP Server)

目标:把“给我一个 URL → 产出可读 Markdown + 可追溯入口”变成一个统一入口,供后续所有业务 skill(github-explorer、写作类 skills、日报等)复用。

核心原则(来自你发的 Excel Skill 拆解文章的启发):

  • 行为规约层:永远给出可追溯入口(原文 URL + 解析产物路径/链接),绝不编造来源。
  • Token 探针:先用低成本 probe 判断可不可以直接抓;不行再走重解析(MinerU)。
  • 反弹机制:失败时返回“下一步动作建议”,而不是一堆异常栈。

工作流(Decision Tree)

输入:url

  1. Domain Whitelist(跳过 probe):若 URL 属于高概率反爬/动态站点(微信/知乎等),直接走 MinerU
  • 白名单文件:references/domain-whitelist.md
  • 对命中白名单的 URL:强制 model_version=MinerU-HTML
  1. Probe(低成本):优先用 web_fetch(url)
  • 目标:拿到正文 markdown(便宜、快)
  • 判断“失败/不合格”条件(见 references/heuristics.md)包括:
    • 403/401/反爬
    • 只有“环境异常/验证码/请在微信打开”等提示
    • 内容极短/明显导航页/丢正文
  1. Fallback(高保真):走 MinerU 官方 API
  • 调用下游 driver:skills/mineru-extract/scripts/mineru_parse_documents.py
  • 对 HTML 页面(微信等):强制 model_version=MinerU-HTML
  1. 输出统一结果合同(Result Contract)

无论用 probe 还是 MinerU,都返回同一套结构:

{
  "ok": true,
  "source_url": "...",
  "engine": "web_fetch" ,
  "markdown": "...",
  "artifacts": {
    "out_dir": "...",
    "markdown_path": "...",
    "zip_path": "..."
  },
  "sources": [
    "原文URL",
    "(如使用MinerU)MinerU full_zip_url",
    "(如使用MinerU)本地markdown_path"
  ],
  "notes": ["任何重要限制/失败原因/下一步建议"]
}

注意:engine 可能是 web_fetchmineru

MinerU 调用(给 agent 的确定性脚本)

当需要 MinerU 时,用这个命令(返回 JSON,且可把 markdown 内联进 JSON,便于下游总结):

python3 mineru-extract/scripts/mineru_parse_documents.py \
  --file-sources "<URL>" \
  --model-version MinerU-HTML \
  --emit-markdown --max-chars 20000

路径说明: 上述命令假设你在 skills 安装根目录下执行。如果 mineru-extract 安装在其他位置,请替换为实际路径。

交付规范(强制)

  • 输出必须包含 sources(原文入口 + 解析产物入口)。
  • 如果 MinerU 成功:必须把 markdown_path(本地路径)写进 sources,方便复查。
  • 如果两条链路都失败:必须明确失败原因,并给出下一步(例如:让 Boss 提供可访问镜像链接 / 允许我用浏览器 relay 导出 HTML / 走上传 HTML 文件解析的兜底方案)。

本 skill 自身不做什么

  • 不跑 MCP Server(避免常驻服务与运维负担)
  • 不试图绕过登录/验证码(这属于访问层问题;我们只做解析层和工作流路由)

How to use content-extract on Cursor

AI-first code editor with Composer

1

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

  • Cursor installed and configured on your development machine
  • Node.js version 16.0+ with npm package manager (verify with node --version)
  • Active project directory or workspace where you want to add content-extract
2

Execute installation command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/blessonism/openclaw-search-skills --skill content-extract

The skills CLI fetches content-extract from GitHub repository blessonism/openclaw-search-skills and configures it for Cursor.

3

Select Cursor when prompted

The CLI will show a list of available agents. Use arrow keys to navigate and space to select Cursor:

◆ Which agents do you want to install to?
│ ── Universal (.agents/skills) ── always included ────
│ • Amp
│ • Antigravity
│ • Cline
│ • Codex
│ ●Cursor(selected)
│ • Cursor
│ • Windsurf
4

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/content-extract

Reload or restart Cursor to activate content-extract. Access the skill through slash commands (e.g., /content-extract) or your agent's skill management interface.

Security & Verification Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.

Implementation Guide

Prerequisites

  • Claude Desktop or compatible AI client with skill support
  • Clear understanding of task or problem to solve
  • Willingness to iterate and refine outputs

Time Estimate

15-45 minutes depending on use case complexity

Installation Steps

  1. 1.Install skill using provided installation command
  2. 2.Test with simple use case relevant to your work
  3. 3.Evaluate output quality and relevance
  4. 4.Iterate on prompts to improve results
  5. 5.Integrate into regular workflow if valuable

Common Pitfalls

  • Expecting perfect results without iteration
  • Not providing enough context in prompts
  • Using skill for tasks outside its intended scope
  • Accepting outputs without review and validation

Best Practices

✓ Do

  • +Start with clear, specific prompts
  • +Provide relevant context and constraints
  • +Review and refine all outputs before using
  • +Iterate to improve output quality
  • +Document successful prompt patterns

✗ Don't

  • Don't use without understanding skill limitations
  • Don't skip validation of outputs
  • Don't share sensitive information in prompts
  • Don't expect skill to replace human judgment

💡 Pro Tips

  • Be specific about desired format and style
  • Ask for multiple options to choose from
  • Request explanations to understand reasoning
  • Combine AI efficiency with human expertise

When to Use This

✓ Use When

Use when skill capabilities match your task, clear ROI on time saved, and you can validate outputs. Best for repetitive tasks, learning, and quality improvement.

✗ Avoid When

Avoid when task requires deep expertise you can't validate, involves sensitive decisions, or when learning process is more valuable than speed of completion.

Learning Path

  1. 1Familiarize yourself with skill capabilities and limitations
  2. 2Start with low-risk, non-critical tasks
  3. 3Progress to more complex and valuable use cases
  4. 4Build expertise through regular use and experimentation
