WHY IT NEEDS A POLICY

Why attach_feed_to_webhook needs a policy

This tool modifies existing webhook subscription state by establishing a new feed-to-webhook binding. While the action is reversible (feeds can be detached via the sibling tool detach_feed_from_webhook), it creates a persistent configuration change that triggers automated delivery of future feed entries to the webhook endpoint.

From the tool's definition Tool description states it will 'attach a feed to a webhook subscription so its new entries get delivered' — this modifies the webhook subscription configuration by adding a feed association, creating a new delivery relationship.
