Use when CVE alerts fire against workloads that are paused, draining, or being decommissioned. Covers feeding workload state into alert routing, suppressing pages for dead namespaces, and keeping a decommission list the agent reads. Not for active-workload CVE triage.
This skill walks through recovering an etcd cluster that rejects writes with mvcc: database space exceeded. It covers confirming the NOSPACE alarm, defragging members one at a time, disarming the alarm, and setting up automatic compaction. Reach for it whenever etcd writes fail while disk space looks fine.
Responds to Karpenter failing to provision nodes for pending pods. Shows how to read the provisioning failure from the controller logs, compare pod requirements against the NodePool, and broaden constraints or capacity. Reach for it when Karpenter logs insufficient capacity or no compatible node.

Distinguishes the two causes behind container exit code 137: OOMKilled (the container exceeded its memory limit) versus node-pressure eviction (the node ran out of memory). Shows how to read the termination reason and fix each. Reach for it when a container dies with 137 and you need to know which memory problem it wa…

Debugs pod evictions caused by the node.kubernetes.io/unreachable NoExecute taint. Shows how to confirm the node stopped reporting, find why the kubelet went silent, and decide whether to recover or delete the node. Reach for it when pods get evicted after a node goes NotReady.

Fixes Kubernetes API 429 Too Many Requests errors caused by client-side throttling. Shows how to identify the hot client from audit logs, then raise its QPS and burst settings or reduce request churn. Reach for it when controllers or automation start failing with 429s under load.
Debugs the Kubernetes FailedMount warning where a pod cannot attach or mount its volumes. Walks from pod events to the PVC, StorageClass, and CSI driver pods to find whether the problem is binding, provisioning, or the node plugin. Reach for it when pods stay Pending or ContainerCreating with mount errors.
Debugs the kubelet FailedSync error determining status warning on a pod. Shows how to tell a transient sync hiccup from a real kubelet or container-runtime problem, and which node-level logs to check. Reach for it when pod status flaps or the warning repeats on one node.
Debugs Airflow KubernetesExecutor pods that never leave Pending: resource requests, node capacity, image pull problems, and scheduler misconfiguration. Use when task pods sit in Pending and tasks never start. Not for pods that start then fail.
Responds to Redis rejecting writes because memory exceeded maxmemory. Use when write commands fail with the OOM error and the instance is otherwise healthy. Not for Redis being down, replication or persistence failures, or read errors.
Fixes Kubernetes rightsizing that measures node CPU while the cluster autoscaler is deliberately keeping utilization low. Use it when an agent recommends smaller nodes for a cluster whose autoscaler is working as designed, or when "low utilization" is the autoscaler's doing. Key trigger: the agent measured node-level …
Responds to Kubernetes node MemoryPressure and DiskPressure conditions: identifying the consuming workloads, relieving the pressure, and preventing repeats. Use it when node conditions show pressure or pods go unschedulable citing it. Not for pod-level OOMKilled or full persistent volumes.
