## Why delete_sub_uid is rated Critical

Deletion of a sub UID is an irreversible action that cannot be undone. It results in permanent loss of an account entity and likely cascading effects on associated permissions, data, and trading activity. This meets the definition of Destructive: 'irreversibly deletes or overwrites data, or actions that cannot be undone'.

From the tool's own definition: "Tool name 'delete_sub_uid' explicitly uses the verb 'delete', and the description states it will 'Delete a sub UID', indicating irreversible removal of a subordinate user account or identity."

## Use case

AI agents call delete_sub_uid 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
{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_sub_uid"
  ]
}
```
