## Why delete_huly_enum is rated Critical

This tool irreversibly removes enum data from the Huly system. While it includes a safety guard (refusing deletion if referenced), the core operation is permanent deletion, which cannot be undone. This places it squarely in the Destructive category, rated high severity due to potential data loss impact. An AI agent misusing this could permanently delete critical enum definitions.

From the tool's own definition: "Tool name explicitly contains 'delete'; description states 'Permanently delete a Huly model enum' and 'Refuses deletion while any attribute references it' — indicating irreversible removal of data with referential integrity checks."

## Use case

AI agents call delete_huly_enum to permanently remove resources in Huly, 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 Huly:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_huly_enum"
  ]
}
```
