This is irreversible once executed, with potentially large financial impact if misused by an AI agent (wrong size, wrong direction, wrong instrument). Financial is the highest severity category and clearly applies here. From the tool's own definition: "'Place a market order to buy or sell' — directly executes a live trade on Bybit exchange, committing financial obligations immediately at market price." ## Use case AI agents use place_market_order to commit financial operations through Bybit, usually the final step of a payment, billing, or trading workflow. A call moves real money. ## Recommended policy (PolicyLayer) Verdict: **Approval-gated**.
