Immediately sell all assets in a symphony (or queue for market open if outside of market hours).
AI agents use liquidate_symphony to commit financial operations through Composer Trade — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This tool sells all assets in a portfolio symphony, which constitutes a major financial action. It moves money by converting all held assets to cash, which is both a financial transaction and potentially irreversible (market conditions change, assets sold cannot be repurchased at the same price). The blast radius is critical: an AI agent misusing this tool could liquidate an entire investment portfolio immediately.
From the tool's definition "Immediately sell all assets in a symphony" — liquidates all holdings, committing irreversible financial transactions
