## Why zernio_create_webhook is rated Medium

Creating a webhook is a Write operation—it creates a new configuration that can receive notifications. While webhooks can be used to trigger external actions, the tool itself merely creates the webhook resource, not the actions themselves. This is reversible (webhooks can be deleted).

From the tool's own definition: "Tool name 'zernio_create_webhook' and description 'Create a new webhook' indicate creation of a new resource (webhook configuration). This is a reversible modification operation."

## Use case

AI agents use zernio_create_webhook to create or update resources in Zernio, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Zernio environment.

## Recommended policy (PolicyLayer)
