Auditing Kubernetes Cluster Rbac
Run a structured Kubernetes RBAC review before release or during production access changes so cluster roles and bindings do not over-privilege workloads or humans.
Overview
Auditing Kubernetes Cluster RBAC is an agent skill most often used in Ship (also Operate) that guides systematic review of Kubernetes roles, cluster roles, and bindings to catch over-privileged access.

- Guides agent-assisted review of Kubernetes RBAC bindings and effective permissions
- Fits pre-ship hardening and post-deploy access-change checks on live clusters
- Aligns with Anthropic cybersecurity skill patterns for infrastructure assurance
- Supports solo builders operating their own EKS, GKE, or self-managed clusters
- Apache 2.0 licensed skill package from a cybersecurity-focused skills collection

What problem does it solve?
You are shipping or operating on Kubernetes but cannot quickly tell which identities can read secrets, patch deployments, or grant themselves admin across namespaces.
Who is it for?
Indie SaaS or API operators on managed or self-hosted Kubernetes who change RBAC infrequently and want agent-guided review checkpoints.
Skip if: Teams that already enforce RBAC exclusively via GitOps policy engines with mandatory CI gates and no manual cluster drift.
When should I use this skill?
Before production Kubernetes deploys or when cluster roles, bindings, or service account permissions change.
What do I get? / Deliverables
You get a structured RBAC audit narrative and remediation-oriented notes you can apply before merge, release, or after an access-model change.
- RBAC findings summary
- prioritized binding and role remediation notes

Journey fit
Spans multiple journey phases - primary shelf plus alternate fits below.
Canonical shelf is Ship because RBAC audits are the standard gate before promoting cluster changes or going live with new services. Security subphase matches identity-and-access review work on Role, ClusterRole, RoleBinding, and ClusterRoleBinding objects.
Where it fits
You stand up a throwaway namespace on a shared cluster and want bindings verified before sharing the demo URL.
You finalize Helm charts with new ServiceAccounts and need a last-pass RBAC review before tag release.
A contractor kubeconfig expired and you must re-audit what their Role still allows after changes.
How it compares
Use for Kubernetes authorization review, not as a substitute for container image vulnerability scanning or network policy design.
Common Questions / FAQ
Who is auditing-kubernetes-cluster-rbac for?
Solo builders and small teams running workloads on Kubernetes who need help reviewing RoleBindings and ClusterRoleBindings before ship or after access changes.
When should I use auditing-kubernetes-cluster-rbac?
During Ship security prep before production cutover, when validating a new namespace layout in Validate-style prototypes on cluster, and during Operate when you rotate credentials or onboard users.
Is auditing-kubernetes-cluster-rbac safe to install?
Review the Security Audits panel on this Prism page for published audit results; the skill may instruct cluster API access—use least-privilege kube contexts and never paste production credentials into untrusted sessions.
