Use kube-score when an agent needs to inspect Kubernetes object definitions and surface recommendations about reliability and security before anything reaches a cluster. Invoke this instead of normal Kubernetes tooling when the job is preflight risk review of manifests or chart output, not schema validation alone and not live cluster administration. The scope boundary is specific and skill-shaped: kube-score performs recommendation-oriented static analysis on Kubernetes manifests before deployment, not general Kubernetes management or a generic platform listing.
