使用说明 (SKILL.md)

Jina Web Fetcher

使用 Jina AI 服务抓取网页内容。

安装

无需安装,直接使用 curl。

使用

# 抓取任意网页
curl -s "https://r.jina.ai/http://目标URL"

# 抓取 Google 搜索结果
curl -s "https://r.jina.ai/http://www.google.com/search?q=搜索词"

示例

# 抓取 GitHub Trending
curl -s "https://r.jina.ai/http://github.com/trending"

# 抓取 Hacker News
curl -s "https://r.jina.ai/http://news.ycombinator.com"

# 抓取特定文章
curl -s "https://r.jina.ai/http://example.com/article"

注意

  • Google 被封锁时使用 r.jina.ai 仍可能被拦截
  • 大部分网站都可以正常抓取
安全使用建议
This skill simply tells the agent to use r.jina.ai as a proxy to fetch any URL. Before installing or using it consider: 1) Privacy/exfiltration — any URL and page contents you ask to fetch will be relayed to r.jina.ai (including potentially sensitive internal endpoints). 2) SSRF risk — you can inadvertently expose internal services by fetching internal URLs through the proxy. 3) Legal/ToS risk — using a proxy to 'bypass search engine restrictions' may violate site terms of service. 4) If you must use it, avoid sending credentials or private/internal URLs, and verify r.jina.ai's privacy policy or run your own trusted proxy instead. If you need simple public-page fetching, prefer a local fetch method under your control.
功能分析
Type: OpenClaw Skill Name: jina-web-fetcher Version: 1.0.0 The skill instructs the AI agent to make external network calls using `curl` to `https://r.jina.ai/` with user-controlled URLs (e.g., `http://目标URL`). This introduces a supply chain risk by relying on an external, third-party service. More critically, it creates a vulnerability for Server-Side Request Forgery (SSRF) against the `r.jina.ai` service if a malicious user provides an internal IP or sensitive URL. Additionally, the direct embedding of user input into a shell command in `SKILL.md` poses a prompt injection risk for the agent if it does not properly sanitize the user-provided URL before execution.
能力评估
Purpose & Capability
The name/description claim to fetch arbitrary webpages (including Google results) via Jina AI. The SKILL.md shows exactly that: curl to r.jina.ai/http://<target>. That is coherent with the stated purpose, though the explicit claim of 'bypass search engine restrictions' raises legal/ToS concerns rather than a technical incoherence.
Instruction Scope
Instructions directly tell the agent to proxy arbitrary URLs through https://r.jina.ai. This means any requested URL (including internal/private addresses or pages requiring auth) and the fetched page contents will be sent to a third party. The SKILL.md does not warn about this, nor does it constrain scope (only public URLs), so the runtime behavior can collect and transmit sensitive data.
Install Mechanism
This is an instruction-only skill with no install steps or code files, so there is no on-disk install risk.
Credentials
The skill requests no credentials, but its ability to fetch arbitrary URLs via a remote proxy is disproportionate: it can be used to access internal network endpoints (SSRF) or to exfiltrate private content to r.jina.ai. No environment variables are required or declared, and the SKILL.md does not disclose that data will be sent to a third party.
Persistence & Privilege
No persistent install or 'always' privilege is requested; the skill is user-invocable and uses normal autonomous invocation defaults.
如何使用
  1. 确保已安装 OpenClaw(本地或 Docker 部署)
  2. 在对话框中输入安装命令:/install jina-web-fetcher
  3. 安装完成后,直接呼叫该 Skill 的名称或使用 /jina-web-fetcher 触发
  4. 根据 Skill 的参数说明提供必要输入,即可获得结构化输出
