Competition K8s Control Plane

Use this skill only as a downstream specialization after $ctf-sandbox-orchestrator is already active and has established sandbox assumptions, node ownership, and evidence priorities. If that has not happened yet, return to $ctf-sandbox-orchestrator first.

Use this skill when the decisive path runs through Kubernetes control-plane state, API permissions, or controller behavior rather than a single container's runtime alone.

Quick Start

1. Separate manifest intent from live cluster state: API objects, mutations, controllers, secrets, and resulting workloads.
2. Identify the active principal first: service account, kubeconfig identity, node credential, webhook, or controller.
3. Map the smallest control-plane edge to its workload effect.
4. Keep RBAC, service accounts, owner references, namespace boundaries, and secret consumers in compact evidence blocks.
5. Reproduce the smallest cluster action that yields the decisive workload or secret effect.

Workflow

1. Map The API Trust Path

• Record namespaces, service accounts, Roles, ClusterRoles, bindings, admission hooks, controllers, and the resources they can mutate.
• Distinguish read access, create access, patch access, exec access, and secret access.
• Keep principal, verb, resource, namespace, and resulting object in one chain.

2. Trace Mutation To Workload State

• Show how an API action becomes a pod, volume mount, secret exposure, env injection, job run, or controller-created artifact.
• Compare checked-in YAML against live objects after defaulting, admission mutation, or controller reconciliation.
• Distinguish pod-runtime behavior from cluster-level mutation logic.

3. Reduce To The Decisive Cluster Path
