version: "1.0.1" name: manage-cluster description: Bring an existing GKE cluster under management on user request (e.g. "manage my cluster <name> in <location>") by creating its Cluster Agent profile, or take one out of management by excluding it. Use whenever a user asks to manage/onboard/watch a specific existing cluster, or to stop managing, exclude or offboard one.

Manage Cluster Skill

When a user asks you to manage (onboard / start watching) a specific existing GKE cluster — e.g. _"manage my cluster payments-prod in us-central1"_ — bring it under management by creating its Cluster Agent profile. After this, the cluster gets a per-cluster agent and is delegable via the kanban board.

This is the explicit, user-driven counterpart to onboarding-time creation (gke-cluster-creation). It is safe to run repeatedly (idempotent).

Steps

1. Gather the target. You need project, cluster, and location.

• Use any values the user gave. If the user omits the project, resolve it:
• default to the platform's active project: gcloud config get-value project; then
• confirm the cluster exists in that project (next step). If it isn't there, or the name is ambiguous, run gcloud container clusters list --format="value(name,location,resourceLabels)" (optionally --project <p>) to locate it, and ask the user only if still ambiguous.

1. Verify the cluster exists before creating a profile (clean error instead of a half-scaffold):

• verify_gke_cluster (platform GKE tool) or gcloud container clusters describe <cluster> --location <location> --project <project> --format="value(status)".
• If it does not exist, tell the user and stop.

1. Create the profile:

``bash python3 /opt/data/scripts/cluster_agent_profile.py create \ --project "<project>" --cluster "<cluster>" --location "<location>" ``

This scaffolds the Cluster Agent profile home on the data PVC, pins a read-only KUBECONFIG to that cluster, stamps its cluster_identity into the profile config and ## Target Cluster Identity into SOUL.md, and prints the profile name. It is idempotent — re-managing an already-managed cluster is a safe no-op.

1. Confirm to the user. Report that <cluster> (<project>/<location>) is now managed: it has a Cluster Agent and is delegable (kanban).

This step gives the cluster an agent immediately. Even without it, the cluster-agent-reconcile cron automatically gives every cluster in every project in scope — including the management cluster where kube-agents runs — an agent on its next run; this skill just does it now.

Stop managing

Because reconciliation manages all clusters in every project in scope, deleting a still-existing cluster's profile alone won't stick — the next reconcile recreates it. To stop managing a cluster:

• Tear down the cluster (see gke-cluster-creation); reconcile prunes its profile automatically.
• Or exclude it: declare the cluster as an exclusion where the install's scope is declared, which depends on how the PlatformAgent is applied. Take that from the request, or ask; the agent cannot read the Helm release record. On an install made with install.sh and upgraded with upgrade.sh (an install.env exists; the Terraform composition applies the chart from it), have the user add project/location/cluster to SCOPE_EXCLUDE_CLUSTERS in install.env and run ./upgrade.sh --upgrade-mode=full, which renders the exclusion into spec.scope.exclude.clusters and the reconcile prunes the profile on its next run. Do not route them to edit the PlatformAgent or the chart values by hand there. A CR edit takes effect at the next reconcile, but the next full upgrade refuses to apply over a spec.scope that install.env does not record, and prints the SCOPE_* lines that would; a helm upgrade by hand is not refused, the next full upgrade renders install.env's scope over it and the profile comes back. On a chart installed with helm install directly, the exclusion is the value platformAgent.scope.exclude.clusters and a helm upgrade; on the composition applied directly, scope.exclude.clusters in its tfvars. On a hand-applied PlatformAgent (no meta.helm.sh/release-name annotation: kubectl get platformagent -n kubeagents-system -o jsonpath='{.items[0].metadata.annotations.meta\.helm\.sh/release-name}', the install's namespace), add an entry {projectId, location, clusterName} to spec.scope.exclude.clusters on it (the operator delivers it to the reconcile, which prunes the profile on its next run). Fleet answers and the per-cluster audits leave an excluded cluster out too, not only the profile. The older RECONCILE_EXCLUDE bare-name variable on the cluster-agent-reconcile cron still works for one release.

Notes

• Requires the cluster to be reachable by the platform's credentials (the create step runs gcloud container clusters get-credentials). If that fails, surface the error — the user may need to grant access.
• The Cluster Agent is read-only; managing a cluster does not grant any mutation ability. Remediation still flows through the Platform Agent's GitOps write path.
