MNS 操作手册（面向 Agent）

MNS (Money Never Sleeps) CLI operations manual for autonomous agents. Tracks an investment portfolio in a local ledger, reads market sentiment (CNN Fear & Greed Index), and generates target-weight rebalancing suggestions. Use when the user asks to view holdings, record a trade they already executed, generate a daily strategy report, inspect or tune strategy parameters, or run a backtest. CRITICAL: MNS connects to NO broker and executes NO trades. `mns buy` / `mns sell` are bookkeeping entries that record trades the human has ALREADY executed elsewhere. Never call them to "act on" a suggestion — doing so silently corrupts every downstream number. Triggers: "查看持仓", "记录买入"…
