gateway_resource_policy_delete
AI agents call gateway_resource_policy_delete to permanently remove resources in Awslabs Valkey — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion of resource policies cannot be undone and would immediately impact authorization rules, potentially locking out legitimate users or exposing resources. This is destructive rather than execute because the action itself (deletion) is the primary effect and cannot be reversed. High severity due to blast radius affecting infrastructure access control.
From the tool's definition Tool name contains 'delete' and operates on 'gateway_resource_policy', which is a policy document that controls access to AWS resources. The name pattern '*_delete' indicates irreversible removal of a resource or configuration.
