## What it does

\`longbridge-portfolio` works with account assets, stock and fund positions, P&L, cash-flow records, statements, margin ratios, and estimated buying power. It also provides workflows for portfolio diagnosis, rebalancing, asset allocation, VaR/CVaR risk analysis, performance attribution, and tax-loss harvesting.

The skill routes requests to reference files and exposes CLI commands such as `assets`, `positions`, `portfolio`, `statement`, `order`, and `dca`. Account data needs Quote permission or Trade permission, depending on the command. `order` and `dca` can change the account, so the agent must show a preview or plan and wait for explicit confirmation. `dca` is limited to AP accounts; Longbridge US accounts do not provide fund positions or margin ratio data.

If the user input is only a slash command, command name, ticker / symbol, or contains no natural-language language signal, you MUST respond in English. Do not infer Chinese from trigger keywords, skill metadata, or examples.
