longbridge-news

Prompt-only skill that aggregates news, filings, and community topics for a single stock — classifies them, distils a fact-only takeaway, and reports sentiment at coarse granularity. May call WebSearch as a clearly-labelled fallback.

Response language: match the user's input language — Simplified Chinese / Traditional Chinese / English.

When to use

• "NVDA 最近新闻", "recent news on NVDA", "NVDA 最近新聞"
• "茅台公告", "700 港交所披露", "NVDA 8-K"
• "市场对 X 财报怎么看", "X 财报后股价为什么跌" — this is news + community
• "X 社区在聊什么", "long port community on NVDA"
• "X 全面综述" (default omnibus)

Depth selection

CLI

Run longbridge <subcommand> --help to verify exact flags. Default omnibus example (run concurrently):

longbridge news NVDA.US --format json
longbridge filing NVDA.US --format json
longbridge topic NVDA.US --format json

Keyword search (no symbol required):

longbridge news search "AI chips" --format json        # search news by keyword
longbridge topic search "NVDA earnings" --format json  # search community topics by keyword

Workflow

1. Resolve symbol; if mapping fails, ask back (this is common with small-caps).

2. Pick depth (table above) and call CLI commands concurrently (see CLI section). If longbridge is not installed, fall back to MCP.

4. Classify the news array into 6 buckets (mandatory — never dump raw titles):

   Bucket	Cues
   catalyst (业绩 / 基本面)	earnings, revenue, guidance, EPS, 财报, 营收, 利润
   regulatory (监管 / 合规)	SEC, 证监会, fine, lawsuit, 调查, 处罚, 罚款
   strategic (战略 / 业务)	acquisition, partnership, launch, 收购, 拆分, 新产品
   financial (资本动作)	buyback, split, dividend, 增发, 回购, 股权激励
   opinion (评级 / 目标价)	upgrade, downgrade, analyst, 评级, 目标价
   other	unclassified

5. Render the structured summary (template below). Skip empty buckets but always include the key-takeaway summary (≤ 100 chars, fact-only).

(Translate into the user's language.)

WebSearch fallback (optional)

Use only when:

• MCP news returns empty, or
• the latest item is > 7 days old, or
• the user asks about a breaking event the MCP dataset has not yet captured.

When you do, prepend: "Below is from a web search — not Longbridge data." / "以下为网络搜索结果,非长桥数据。" / "以下為網絡搜尋結果,非長橋數據。"

Output constraints

• Must classify into the 6 buckets — never dump raw titles.
• Must include the key-takeaway summary (≤ 100 chars, fact-only).
• Must end with the not-investment-advice disclaimer.
• 给有证据的方向性判断，例如 "市场普遍将此解读为正面 / 负面"；避免只贴 "利好 / 利空" 标签而不附事实。
• Do not quote individual community comments verbatim (cherry-pick risk); report sentiment as a coarse skew.
• Do not invent news. If MCP is sparse, say so and offer WebSearch.

Compliance: hype vocabulary

If topic / topic_replies content contains a high density of hype words — "涨停板", "主升浪", "必涨", "满仓", "all in", "庄家", "次新妖股" — do not echo them. Downgrade to "discussion contains a notable share of speculative posts" and move on.

Error handling

MCP fallback

If longbridge CLI is not installed (command not found), use MCP tools instead:

When the CLI is unavailable, fall back to the MCP server. Discover available tools from the MCP server's tool list at runtime — do not rely on hardcoded tool names.

MCP setup: claude mcp add --transport http longbridge https://openapi.longbridge.com/mcp (quote scope).
