## Why cancel_order is rated Critical

Cancelling an order removes it from the order book permanently. While no money is directly moved, the action is irreversible (the cancelled order cannot be reinstated) and occurs in a financial trading context, making it Destructive with high severity due to potential trading impact.

From the tool's own definition: "'Cancel a specific order' — cancelling an order is an irreversible action that terminates a live trading order and cannot be undone."

## Use case

AI agents call cancel_order to permanently remove resources in Bybit, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Bybit:

```json
