Workflow

Step 1: Determine Fetch Target

Based on the user's request, pick the right source(s) and category:

Step 2: Fetch Using web_fetch

Use the web_fetch tool with extractMode=text to get clean text content. Set maxChars appropriately:

web_fetch:
  url: "\x3Csource-url>"
  extractMode: text
  maxChars: 8000   # per page, enough for ~5-10 headlines + snippets

Example fetches:

• 新浪财经要闻: https://finance.sina.com.cn/
• 新浪财经期货: https://finance.sina.com.cn/futures/
• 东方财富快讯: https://www.eastmoney.com/
• 金十数据: https://www.jin10.com/

Respect robots.txt: Use moderate fetch intervals and reasonable maxChars. Do not scrape at high frequency.

Step 3: Classify News by Sector

Parse fetched text and classify each news item. Look for keywords in headline and body:

Output format — group news under their sector heading:

### 🏛️ 宏观宏观
1. [标题] — 摘要（来源，时间）
2. [标题] — 摘要（来源，时间）

Step 4: Generate Summary (AI)

For each news item (or at least the top 5-8 most important ones), produce a one-line summary:

• Length: 20-40 Chinese characters max
• Style: Concise, fact-only, no opinion
• Focus: What happened + why it matters to markets

Example:

❌ 不好: "央行宣布降准0.5个百分点，市场流动性得到改善"
✅ 好: "央行降准0.5%，释放长期资金约1万亿"

Step 5: Extract Keywords

Extract 2-5 key terms per news item. Prioritize actionable terms that traders care about:

• Policy actions: "降准", "加息", "限产", "收储"
• Price levels: "突破 XXXX", "创 X 年新高"
• Supply/demand: "减产", "累库", "检修", "开工率"
• Events: "交割", "移仓", "基差", "价差"

Step 6: Sentiment Analysis

Tag each news item with a sentiment direction:

Apply sentiment relative to the sector/contract, not the general economy. E.g., "原油增产" = 🔴 偏空 for oil.

Step 7: Importance Ranking

Rank news items by market impact (high → low):

Step 8: Format Final Output

Use this output format as the final presentation:

Scripts

scripts/fetch_news.py

A Python script for batch fetching from multiple sources. Use when the user needs a consolidated multi-source fetch (not individual page fetches via web_fetch).

python scripts/fetch_news.py --sources sina,jin10 --sectors macro,agri --max-items 20

Parameters:

• --sources: Comma-separated source list (sina, eastmoney, hexun, jin10)
• --sectors: Filter by sector keywords
• --max-items: Max items to return (default 20)
• --output: Output format (text, json)

Important Notes

• Don't over-fetch: One fetch per source per scenario is enough. ~5-8k chars per fetch.
• Source attribution: Always include the source name for each news item — credibility matters.
• Timestamps: Include approximate time if available (e.g., "10:23", "昨夜").
• Cross-reference: When a key event is reported differently across sources, note discrepancies.
• No forward-looking statements: Summarize what happened, don't predict outcomes.
• Respect robots.txt: Do not scrape at high frequency; reasonable intervals only.
