  "description": "Conversational Solana trading agent. Live with real funds, non-custodial: manual trades are signed by the user's own wallet; automated rule buys are signed by Opal's key within a user-set, revocable spending limit. Stop-loss and take-profit levels always alert you. They also sell for you on one narrow path: a position a rule opened in your automation wallet with those levels set on the rule. Opal cannot sell from a wallet you hold yourself, and a level you add to any other position only alerts you. The skills listed on this card are read-only market data; the same endpoint also exposes `swap`, which executes a real-fund trade, to an authenticated caller.",
