What this skill tells your AI

The instructions your AI receives, as published by woodfishhhh/ez_math_model in skills/ez-math-model/tools/webcrawl/SKILL.md and read by ahel’s review.

何时使用

  • 题目纯数学 / 物理机理 → 不要启用
  • 题目涉及行业 / 政策 / 地理 / 经济 → 启用。
  • 评价类题目需要业界基准 / 标准 → 启用。

入口决策树

有具体 URL 要读 → Jina Reader(免费,零配置)
  失败 → Firecrawl scrape(要 EZMM_FIRECRAWL_KEY)
  失败 → 让 LLM 用 WebFetch(最后兜底)

要先搜后读 → Tavily(要 EZMM_TAVILY_KEY)
            / Exa(要 EZMM_EXA_KEY)
            / SerpAPI(要 EZMM_SERPAPI_KEY)
全部不可用 → 让用户给具体 URL,再走单页抓取

命令模板

Jina Reader(免费)

# 任意 URL → markdown,零配置
$url = 'https://example.com/article'
Invoke-RestMethod -Uri "https://r.jina.ai/$url" -OutFile workdir/.../web/$(($url | Get-FileHash -Algorithm MD5).Hash.Substring(0,8)).md

Firecrawl

import requests, os
r = requests.post(
    "https://api.firecrawl.dev/v1/scrape",
    headers={"Authorization": f"Bearer {os.environ['EZMM_FIRECRAWL_KEY']}"},
    json={"url": "https://...", "formats": ["markdown"]},
    timeout=60,
).json()
markdown = r["data"]["markdown"]

Tavily / Exa / SerpAPI

参考 tools/webcrawl/SKILL.md 的代码段。

落盘规范

抓回的页面落到:

workdir/{task_id}/attachments/external/web/<sha8>.md

文件头三行写:

<!-- source: tavily | firecrawl | jina | exa | serp -->
<!-- fetched_at: 2026-05-20T10:00:00+08:00 -->
<!-- url: https://... -->

礼貌爬取

  • 单源间隔 ≥ 1s
  • 尊重 robots.txt(除非用户授权)
  • 不绕过登录 / 反爬
  • 大批量爬取走 Firecrawl,不裸 requests

失败诊断

情况处理
全部 key 缺失仅 Jina 可用;写诊断说明可用工具集
单页 4xx / 5xx退避重试 1 次;仍失败记诊断
抓回登录墙 / 验证码不绕过;写诊断
超时 > 60s中断,写诊断
