WHAT IT DOES

What manage_k8s_resource does on Awslabs Valkey

AI agents invoke manage_k8s_resource to trigger actions in Awslabs Valkey. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why manage_k8s_resource needs a policy

The name 'manage_k8s_resource' strongly implies performing operations on Kubernetes resources. 'Manage' is a broad verb that could span creating, updating, or deleting K8s resources (pods, deployments, services, etc.), which can have significant impact. Without a description, exact behavior is unknown, but management operations on infrastructure are at minimum Execute-level.
