Magpie

magpie — A-share quote & alert agent skill

🐦 magpie is a local daemon at http://127.0.0.1:17891 exposing a tiny HTTP API. This skill teaches you how to call it. The daemon must already be running — if /health fails, tell the user to magpie start.

When to activate

• "茅台现在多少" / "查 600519" / "海康威视" → quote lookup
• "今天主力资金流向" / "X 股票主力流入多少" → fund flow
• "给 600519 设个 1500 突破告警" / "茅台跌破 1300 提醒我" → add alert
• "看看我自选股" / "我加了哪些股" → watchlist
• "今天龙虎榜" / "谁上龙虎榜了" → lhb
• "早盘要点" / "收盘复盘" / "周报" → digest
• "今天我的盘怎么样" → digest evening
• "K 线" / "最近 X 天怎么样" → kline

Don't activate

• 美股 / 港股 / 加密币（v1 不支持）
• 选股策略 / 技术分析 / 买卖建议（magpie 是监控工具，非投资建议）
• 写策略 / 回测 / 下单
• 新闻 / 公告 / 财报数据

Health check first

Always check /health before issuing requests. If down:

curl -s http://127.0.0.1:17891/api/v1/health

If non-200 / connection refused, tell user:

"magpie daemon 没启动，请运行 cd /Volumes/DevDisk/symbol/magpie && node dist/cli.js start（或如果已安装 npm 包，magpie start）。"

HTTP API reference

Base URL: http://127.0.0.1:17891

Quotes

# Single
curl -s "http://127.0.0.1:17891/api/v1/quote/600519"

# Batch
curl -s "http://127.0.0.1:17891/api/v1/quotes?codes=600519,000858,002594"

Response shape:

{
  "ok": true,
  "quote": {
    "code": "600519", "name": "贵州茅台",
    "price": 1344.09, "change": -10.46, "changePct": -0.77,
    "open": 1354.5, "prevClose": 1354.55,
    "high": 1358.6, "low": 1338,
    "volume": 5696787, "turnover": 7653257144,
    "source": "sina", "delaySec": 5
  }
}

Stock code rules:

• 6 digits, no prefix needed — 600519 not sh600519
• 上海: 6xxxxx / 9xxxxx
• 深圳: 0xxxxx / 3xxxxx
• 北交所: 8xxxxx / 4xxxxx

If user gave a stock name, you need to know the code. Try this order:

1. Reverse-lookup the watchlist first — GET /watchlist to see if user already added it (matches by name substring)
2. Use the common-stock table below
3. If still unknown, ask the user for the 6-digit code, don't guess

Common Chinese A-share stocks (verified):

• 贵州茅台 600519 / 五粮液 000858 / 泸州老窖 000568 / 山西汾酒 600809
• 比亚迪 002594 / 宁德时代 300750 / 長城汽车 601633
• 中国平安 601318 / 招商银行 600036 / 平安银行 000001 / 工商银行 601398
• 海康威视 002415 / 美的集团 000333 / 万科A 000002 / 中国中车 601766
• 海尔智家 600690 / 隆基绿能 601012 / 长江电力 600900
• 世纪华通 002602 / 京东方 A 000725 / 洁美科技 002859 / 巨人网络 002558

Ambiguous abbreviations — always ask the user to clarify:

• “平安” → 中国平安 (601318) or 平安银行 (000001)?
• “招行 / 招商” → 招商银行 (600036) 是常规映射但确认一句更稳
• “万科” → 万科A (000002) vs 万科企业 (000540) etc.

If in doubt, ask: "你指的是哪个股票？请给 6 位代码。"

Note: stock names from sina data source occasionally arrive with full/half-width spaces (e.g. 五 粮 液). magpie v0.0.3+ trims these in the server. If you ever see one, just trim before rendering.

Fund flow（资金流）

curl -s "http://127.0.0.1:17891/api/v1/flow/600519"

Units are CNY (元). Divide by 1e8 for 亿. Negative = 净流出，positive = 净流入.

Fields: mainNetIn (主力), superNetIn (超大单), bigNetIn (大单), midNetIn (中单), smallNetIn (小单).

Rendering rule (do not parrot negative numbers):

• value < 0 → 净流出 ¥{abs(v/1e8).toFixed(2)} 亿
• value > 0 → 净流入 ¥{(v/1e8).toFixed(2)} 亿
• value 0 → 持平

delaySec is usually 60s for flow (vs 5s for quote). If user is asking real-time, add a hint: "资金流数据延迟~1min、以交所清算为准".

K-line（K线）

curl -s "http://127.0.0.1:17891/api/v1/kline/600519?period=daily&days=30"

period ∈ daily|weekly|monthly. Default 30 rows. Rows have date, open, close, high, low, volume, turnover, changePct, change, turnoverRate.

龙虎榜 lhb

curl -s "http://127.0.0.1:17891/api/v1/lhb"                      # today
curl -s "http://127.0.0.1:17891/api/v1/lhb?date=2026-05-13"      # specific date

Returns up to 50 rows. After 18:00 SH local is most reliable.

How to respond to common asks

"查 X" / "X 现在多少"

1. Map name → 6-digit code (or ask)
2. GET /quote/<code>
3. Reply concise: 贵州茅台 600519: ¥1344.09 📉 -0.77% (今高 ¥1358.6 / 今低 ¥1338)
4. If delaySec > 30 add: "数据延迟 Xs"

"X 资金流"

1. GET /flow/<code>
2. Convert to 亿元 (/1e8), highlight mainNetIn. Negative → say "净流出"，不要写负号。
3. Default report: main + super 两项足够。
   • Concise: 茅台 600519 主力净流出 ¥11.78 亿（超大单净流出 ¥11.55 亿）
4. “详细” / “全部” 才担 mid/small：· 大单 -0.23 亿 · 中单 +11.78 亿 · 小单 -0.003 亿

"给 X 设个 ¥N 告警"

1. Determine type:
   • 跌破/止损 → lte (价格简单 ≤) or breakdown (需 prevClose > threshold)
   • 突破/止盈 → gte (价格简单 ≥) or breakout (需 prevClose < threshold)
2. POST /alerts with {code, type, threshold, note}
3. Confirm template by type (don't free-style):
   • gte → ✓ 规则 #N 已添加：{name} ({code}) 涨到 ¥{th} ping 你
   • lte → ✓ 规则 #N 已添加：{name} ({code}) 跌到 ¥{th} ping 你
   • breakout → ✓ 规则 #N 已添加：{name} ({code}) 突破 ¥{th} ping 你
   • breakdown → ✓ 规则 #N 已添加：{name} ({code}) 跌破 ¥{th} ping 你
4. Distance hint (optional but nice): if current price differs from threshold by >5%, append （当前 ¥{p}，距阈值 {+±X%}）

"今天我的盘"

1. GET /digest?type=evening (after 15:00) or morning (before 09:30)
2. Return the digest.markdown verbatim — already formatted nicely

"今天龙虎榜"

1. GET /lhb (after 18:00 SH for stable data)
2. Summarize top 3-5 with reasons, don't dump all 50

Market phase semantics (from /health)

Unknown phase value → fall back to "closed" handling.

Output style

• Numbers: prices always with ¥ prefix and 2 decimals; percentages with sign and 2 decimals
• Direction emoji: 📈 涨 / 📉 跌 / ➖ 平
• Brevity: a single line per stock unless user asks for detail
• Disclaimer: 不要给买卖建议；如果用户问"该买吗"，回答"magpie 只看数据，不建议买卖决策"
