## Why ae_delete_layer is rated Critical

This tool irreversibly deletes data (a layer from an After Effects composition) and cannot be undone programmatically. Deletion of composition layers is a destructive operation that destroys work product. The high severity reflects that an AI agent could accidentally or maliciously remove critical animation layers, requiring manual recreation of work.

From the tool's own definition: "Tool name contains 'delete' and description states 'Remove a layer from the composition permanently'. The word 'permanently' indicates irreversible deletion."

## Use case

AI agents call ae_delete_layer to permanently remove resources in Ae, 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 Ae:

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