name	longbridge-peer-comparison
description	Cross-symbol comparison (2–5 stocks) via Longbridge — valuation (PE / PB / PS / dividend yield), current price + change, latest financial KPIs (revenue / net income / ROE), market cap. Renders as a single matrix; flags cross-currency or cross-industry caveats. Triggers: "X 和 Y 哪个值得买", "X vs Y", "几只股票对比", "同行业谁最强", "X 跟 Y 谁更便宜", "几只哪个增速快", "科技七姐妹谁最强", "X 跟 Y 對比", "X 跟 Y 哪個便宜", "X vs Y", "compare X and Y", "peer comparison", "which is more expensive", "which has higher growth".

longbridge-peer-comparison

Prompt-only skill that takes 2–5 symbols, runs the same per-symbol orchestration concurrently, and renders one normalised matrix.

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

When to use

• "茅台 五粮液 哪个便宜", "AAPL vs GOOG vs MSFT"
• "NVDA AMD 哪个增速快", "科技七姐妹谁最强"
• "茅台跟 700 谁估值低" (cross-currency + cross-industry — render with explicit disclaimer)

Symbol-count rules

Count	Behaviour
0	Ask: "Which symbols would you like to compare?"
1	Reroute → longbridge-valuation (#14) or longbridge-fundamental (#15)
2–5	Run normally
≥ 6	Ask user to narrow to 3–5 ("matrix becomes unreadable beyond 5")

Cross-cohort caveats

• Cross-currency (e.g. NVDA.US + 600519.SH) → render the matrix; add an explicit disclaimer at the top of the table: "cross-currency comparison shows relative levels only; no FX conversion is applied".
• Cross-industry (e.g. tech + spirits) → render the matrix; add: "cross-industry comparison has limited meaning — valuation thresholds are not comparable".
• Cross-market (different accounting standards: IFRS / US GAAP / CN GAAP) → add: "data uses different accounting standards; treat as a rough benchmark."

CLI

Run longbridge --help to see all available subcommands, then longbridge <subcommand> --help before calling. Types of data needed per symbol (run concurrently for all symbols):

• Real-time quote (last price, change)
• Valuation indices (PE, PB, PS, dividend yield, market cap)
• Financial KPIs from the most recent report (revenue, net income, ROE) — headline figures only, not full statements
• Historical valuation data

# Always check flags first, then call — example structure:
longbridge <subcommand> NVDA.US --format json

Workflow

1. Resolve every symbol to <CODE>.<MARKET>. Apply the count rules above.

2. Concurrently per symbol, call CLI commands (see CLI section). If longbridge is not installed, fall back to MCP.

3. Do not pull the full IS/BS/CF — financial-report headline fields are enough for the KPIs.

4. Normalise (label currency on every figure; do not auto-convert FX). Render as a Markdown table — rows are dimensions, columns are symbols.

5. Add the observations paragraph at the bottom (data-only, no winners).

Output template

{symbol₁ vs symbol₂ vs ...} comparison — Source: Longbridge Securities
[If cross-currency / cross-industry / cross-market: disclaimer here]

| Dimension | Symbol₁ | Symbol₂ | Symbol₃ |
|---|---|---|---|
| Last (CCY) | ... | ... | ... |
| Today's change | ... | ... | ... |
| Market cap | ... | ... | ... |
| **Valuation** | | | |
| PE (TTM) | ... | ... | ... |
| PB | ... | ... | ... |
| PS | ... | ... | ... |
| Dividend yield | ... | ... | ... |
| **Financials (latest period)** | | | |
| Revenue YoY | ... | ... | ... |
| Net income YoY | ... | ... | ... |
| ROE | ... | ... | ... |

[Observations]
- Valuation: who is highest / lowest on PE / PB / PS
- Growth: who leads on revenue / net income YoY
- Dividend: highest yield
- Scale: market-cap ratios

Output constraints

• Must be a Markdown table, dimensions × symbols.
• Must label currency on every numeric figure (CNY / USD / HKD / SGD); no auto-FX conversion.
• Must end with not-investment-advice disclaimer.
• Cross-currency / cross-industry / cross-market → must include the disclaimer at the top of the table.

Performance note

2–5 symbols × 4 tools = 8–20 MCP calls. Latency may be visible. If the user gives 5 symbols, optionally tell them "comparing 5 symbols, fetching in parallel..." before delivering.

Error handling

Situation	Reply
command not found: longbridge	Fall back to MCP; if MCP also unavailable, tell user to install longbridge-terminal.
Some symbols' data missing	Render N/A in those rows; explain which symbol(s) failed
1 symbol only	Reroute to longbridge-valuation / longbridge-fundamental
≥ 6 symbols	Trim to top 5; tell user the rest are dropped
stderr not logged in	Tell user to run longbridge auth login.

MCP fallback

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

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).
