## Why delete_group_milestone is rated Critical

Deleting a group milestone permanently removes organizational project planning data that cannot be recovered. This qualifies as Destructive (most severe applicable category) rather than Write, as the operation is irreversible.

From the tool's own definition: "Tool name explicitly states 'delete' and description confirms 'Delete a group milestone' — this is an irreversible deletion operation that destroys data without undo capability."

## Use case

AI agents call delete_group_milestone to permanently remove resources in Gitlab Mcp, 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 Gitlab Mcp:

```json

  ]
}
```
