Task Router Skill
Task Router
Optimizes web fetching by using Cloudflare's Markdown for Agents, reducing token consumption by ~80%
Follow the repository instructions for this skill and your agent. Review the files and dependencies before adding it to your workflow.

Give your agent the source link and ask it to inspect instructions and dependencies before explaining the installation steps.
Cloudflare 推出 Markdown for Agents 功能:
在需要网页抓取时,使用优化后的 fetch 函数:
const { optimizedFetch } = require('./markdown-fetch');
const result = await optimizedFetch('https://example.com');
// result.markdown - Markdown 内容(如果有)
// result.html - HTML 内容(备用)
// result.tokensSaved - 节省的 tokens(如果有)
async function optimizedFetch(url, options = {}) {
const headers = {
'Accept': 'text/markdown, text/html',
...options.headers
};
const response = await fetch(url, { ...options, headers });
const contentType = response.headers.get('content-type');
const xMarkdownTokens = response.headers.get('x-markdown-tokens');
let result = {
url,
contentType,
tokensSaved: xMarkdownTokens ? parseInt(xMarkdownTokens) : null
};
if (contentType.includes('text/markdown')) {
result.markdown = await response.text();
result.format = 'markdown';
} else {
result.html = await response.text();
result.format = 'html';
}
return result;
}
| Content-Type | 处理方式 |
|---|---|
| text/markdown | 直接使用,跳过 HTML 解析 |
| text/html | 走原有解析逻辑 |
如果响应中有 x-markdown-tokens header,记录到日志:
if (result.tokensSaved) {
console.log(`[Markdown Fetch] Token 节省: ${result.tokensSaved}`);
}
找一个 Cloudflare 托管的网站测试:
curl -H "Accept: text/markdown, text/html" https://cloudflare-example.com
确认收到 content-type: text/markdown 响应。

# Markdown Fetch - 网页抓取优化
## 背景
Cloudflare 推出 **Markdown for Agents** 功能:
- AI 请求时返回 Markdown 格式
- Token 消耗比 HTML 减少约 80%
## 使用方法
在需要网页抓取时,使用优化后的 fetch 函数:
```javascript
const { optimizedFetch } = require('./markdown-fetch');
const result = await optimizedFetch('https://example.com');
// result.markdown - Markdown 内容(如果有)
// result.html - HTML 内容(备用)
// result.tokensSaved - 节省的 tokens(如果有)
```
## 核心逻辑
```javascript
async function optimizedFetch(url, options = {}) {
const headers = {
'Accept': 'text/markdown, text/html',
...options.headers
};
const response = await fetch(url, { ...options, headers });
const contentType = response.headers.get('content-type');
const xMarkdownTokens = response.headers.get('x-markdown-tokens');
let result = {
url,
contentType,
tokensSaved: xMarkdownTokens ? parseInt(xMarkdownTokens) : null
};
if (contentType.includes('text/markdown')) {
result.markdown = await response.text();
result.format = 'markdown';
} else {
result.html = await response.text();
result.format = 'html';
}
return result;
}
```
## 响应处理
| Content-Type | 处理方式 |
|--------------|----------|
| text/markdown | 直接使用,跳过 HTML 解析 |
| text/html | 走原有解析逻辑 |
## 可选:x-markdown-tokens 日志
如果响应中有 `x-markdown-tokens` header,记录到日志:
```javascript
if (result.tokensSaved) {
console.log(`[Markdown Fetch] Token 节省: ${result.tokensSaved}`);
}
```
## 改动范围
1. 找到所有 HTTP 请求(fetch/axios/request)
2. 统一添加 header
3. 响应处理加判断
## 测试验证
找一个 Cloudflare 托管的网站测试:
```bash
curl -H "Accept: text/markdown, text/html" https://cloudflare-example.com
```
确认收到 `content-type: text/markdown` 响应。Task Router
