Authentication & Environment

Required Environment Variable

export XQ_A_TOKEN="value_of_xq_a_token"

You must check if $XQ_A_TOKEN is set before execution. If not set, prompt:

Please set your Snowball Token first: export XQ_A_TOKEN="your_token" How to obtain: Open xueqiu.com in browser → Login → F12 → Application → Cookies → Copy xq_a_token value.

Technical Architecture

Data	API Domain	Method	Reason
Influencer Updates	xueqiu.com	Playwright + stealth	Main domain has Alibaba Cloud WAF, curl cannot bypass
Watchlist	stock.xueqiu.com	Playwright (browser fetch)	Needs browser context for full auth cookies
Single Stock Quote	stock.xueqiu.com	curl	Subdomain has no WAF, only needs xq_a_token

Dependency Installation

The skill directory contains install.sh. Run it once before first use:

bash {baseDir}/install.sh

Manual installation:

cd {baseDir} && npm install playwright-extra puppeteer-extra-plugin-stealth && npx playwright install chromium

Configuration Files

{baseDir}/watchlist.json — Influencer Watchlist

[
  { "user_id": "1247347556", "name": "Duan Yongping", "note": "Value Investing" },
  { "user_id": "5819606767", "name": "Shi Laomao", "note": "HK Stocks Deep Dive" }
]

• user_id: Obtained from Snowball personal page URL xueqiu.com/u/{user_id}
• note: Tag used to annotate influencer expertise in the report

{baseDir}/portfolio.json — Portfolio Configuration (Optional)

{
  "positions": [
    { "symbol": "SH600519", "name": "Kweichow Moutai", "shares": 100, "cost": 1680.00 },
    { "symbol": "00700", "name": "Tencent Holdings", "shares": 500, "cost": 320.00 }
  ]
}

If portfolio.json exists with position data, the report will calculate profit/loss.

If portfolio.json does not exist or is empty, automatically fetch the user's Snowball watchlist as targets. In this case, share counts and cost prices are unavailable; no P&L is calculated, only quotes are displayed.

Data Fetching Script

{baseDir}/fetch_timeline.js provides three subcommands:

1. Fetch Influencer Updates

node {baseDir}/fetch_timeline.js timeline "{user_id1},{user_id2},..." [count]

• Launches headless Chromium via Playwright + stealth
• First visits xueqiu.com homepage to bypass WAF (JS execution + cookie setting)
• Then navigates to each user's update API in sequence
• Request interval: 1.5 seconds, default 5 original posts per user (type=10)
• Post body stripped of HTML tags, truncated to first 500 characters

Output format (stdout):

{
  "{user_id}": {
    "statuses": [
      {
        "id": 376485375,
        "title": "",
        "text": "Post plain text...",
        "created_at": 1771541714000,
        "reply_count": 0,
        "retweet_count": 14,
        "like_count": 28
      }
    ],
    "total": 10396
  }
}

Post link: https://xueqiu.com/{user_id}/{status_id}

2. Fetch Watchlist

node {baseDir}/fetch_timeline.js watchlist

Returns all watchlist symbols and names from the user's Snowball account.

3. Fetch Watchlist + Real-time Quotes (Recommended)

node {baseDir}/fetch_timeline.js watchlist_quotes

Returns the watchlist and real-time quotes for each stock (current price, change %, PE, market cap, etc.) in one call.

Output format (stdout):

{
  "stocks": [
    {
      "symbol": "00700",
      "name": "Tencent Holdings",
      "current": 522.0,
      "percent": -2.06,
      "chg": -11.0,
      "high": 533.0,
      "low": 518.0,
      "last_close": 533.0,
      "pe_ttm": 20.64,
      "pb": 3.62,
      "dividend_yield": 0.87,
      "market_capital": 4753517897250,
      "currency": "HKD",
      "exchange": "HK"
    }
  ]
}

4. Supplement: Single Stock Quote (curl fallback)

The quotes subdomain has no WAF, can be called directly with curl:

curl -s -b 'xq_a_token=TOKEN' -H 'User-Agent: Mozilla/5.0' -H 'Referer: https://xueqiu.com/' \
  'https://stock.xueqiu.com/v5/stock/quote.json?symbol={symbol}&extend=detail' \
  | jq '.data.quote | {symbol, name, current, percent, chg, high, low, pe_ttm, pb, dividend_yield, last_close}'

---

Execution Flow

Execute in the following order. Steps 2 and 3 can run in parallel:

Step 1: Check Environment

• Verify $XQ_A_TOKEN is set
• Read {baseDir}/watchlist.json (influencer list)
• Read {baseDir}/portfolio.json (if exists)

Step 2: Fetch Influencer Updates

node {baseDir}/fetch_timeline.js timeline "{all_user_ids_comma_separated}" 5

Extract all user_ids from watchlist.json, join with commas, single call.

Step 3: Fetch Watchlist Quotes

Option A: portfolio.json exists with positions — use curl to query each position's quote one by one (no Playwright needed).

Option B: portfolio.json does not exist or is empty — use Playwright to fetch Snowball watchlist + quotes:

node {baseDir}/fetch_timeline.js watchlist_quotes

Step 4: Summary Analysis

Combine influencer updates and stock quote data, output according to the report format below.

---

Report Output Format

Strictly follow the five-section structure below:

---

1. Influencer Opinion Summary

Grouped by person. For each influencer, include:

• Influencer Nickname (tag from watchlist.json note field)
• For each post, extract 1-2 core viewpoints, displayed in a table (including interaction data)
• Summarize specific stock symbols or sector directions mentioned by that influencer

2. Watchlist Quote Overview

Group by market (HK Stocks / US Stocks / A-shares), display in Markdown table:

Stock	Symbol	Current Price	Change %	PE(TTM)	Market Cap

If portfolio.json position data exists, add columns:

Stock	Symbol	Current Price	Change %	Shares Held	Cost Price	P&L Amount	P&L %

P&L Amount = (Current Price - Cost Price) × Shares Held P&L % = (Current Price - Cost Price) / Cost Price × 100%

Note the currency unit for different markets (CNY / HKD / USD).

3. Correlation Analysis Between Influencer Views and Holdings

• Check each influencer's posts for direct mentions of stock symbols or company names in the user's watchlist
• Check for mentions of related sectors (e.g., tech, consumer, new energy, finance, etc.)
• Mark bullish/bearish signals for each correlated item
• Point out consensus or divergence in views between influencers

4. Investment Reference Suggestions

Based on the above analysis, provide personalized references:

• Possible reasons for stocks in the watchlist with abnormal daily change (>3% or <-3%)
• Opportunities where influencers have a consensus bullish view
• Risk points to watch
• Possible action ideas (for reference only)

5. Disclaimer

The above content is automatically generated by AI based on Snowball public information and does not constitute any investment advice. Investing involves risk, and decisions should be made with caution. Data may be delayed; please refer to actual market quotes. Influencer views represent only their personal opinions.

Error Handling

Error Scenario	Detection Method	Handling
Token not set	$XQ_A_TOKEN empty	Prompt user to set and explain how to obtain
Playwright not installed	node reports MODULE_NOT_FOUND	Prompt to run bash {baseDir}/install.sh
WAF slider verification	Returns "Access Verification"	Advise to retry later
Token expired	Returns error_code 400/400016	Prompt to get a new token
Watchlist empty	watchlist_quotes returns empty stocks	Prompt user to add stocks in Snowball App
Influencer not found	Returns empty statuses	Skip that user, annotate in report
API rate limit	HTTP 429 or consecutive errors	Wait and retry
Network error	Request timeout	Prompt to check network

Principle: Partial failure should not interrupt the entire workflow. If influencer updates fail, still output the quotes report; if quotes fail, still output the influencer summary.
