scitix/siclaw

Skill Claude CodeCodex

Analyze cluster-wide Kubernetes events to identify issues and patterns. Aggregates Warning events, detects high-frequency patterns, and correlates related events.

scitix/siclaw

Skill Claude CodeCodex

Diagnose Deployment rollout failures (stuck rollouts, ProgressDeadlineExceeded, replica mismatch). Checks rollout status, ReplicaSets, and new pod health to identify why an update is failing.

scitix/siclaw

Skill Claude CodeCodex

Diagnose DNS resolution failures in the cluster (NXDOMAIN, timeouts, SERVFAIL). Checks CoreDNS health, service endpoints, and DNS configuration.

scitix/siclaw

Skill Claude CodeCodex

Show and ping the gateway of a network interface, on a Kubernetes node or inside a pod's network namespace. Auto-detects the gateway from the routing table (ip -j route), reports interface type (RoCE / Ethernet / IB), and tests reachability with ping. Use for default-route / gateway questions, network reachability…

scitix/siclaw

Skill Claude CodeCodex

Diagnose HorizontalPodAutoscaler failures (not scaling, metrics unavailable, target mismatch). Checks HPA status, metrics-server health, and scaling events to identify why autoscaling is not working.

scitix/siclaw

Skill Claude CodeCodex

Count HTTP status codes and request-duration distribution from an ingress controller's access log, over a fixed time window, in one pass. Use when asked "how many 503s", "how many requests took over 60s", "what's the status code / latency distribution" for a service — i.e. a MEASUREMENT question about traffic, not a…

scitix/siclaw

Skill Claude CodeCodex

Diagnose container image pull failures (ErrImagePull / ImagePullBackOff). Checks pod status, containerd logs, and events to identify root cause.

scitix/siclaw

Skill Claude CodeCodex

Diagnose Ingress failures (rules not matching, backend unreachable, TLS errors, no address assigned). Checks Ingress resources, IngressClass, backend Services, and controller health to identify why external traffic is not routed correctly.

scitix/siclaw

Skill Claude CodeCodex

Diagnose Job and CronJob failures (BackoffLimitExceeded, DeadlineExceeded, pods failing, CronJob not triggering). Checks Job status, pod logs, and CronJob schedule to identify why batch workloads are failing.

scitix/siclaw

Skill Claude CodeCodex

Diagnose NetworkPolicy-related connectivity issues (traffic unexpectedly blocked, default-deny effects, egress blocking DNS). Identifies which NetworkPolicies affect a pod, checks ingress/egress rules, and verifies CNI support.

scitix/siclaw

Skill Claude CodeCodex

Check node health and diagnose node-level issues (NotReady, DiskPressure, MemoryPressure, PIDPressure). Inspects node conditions, resource allocation, and real-time usage.

scitix/siclaw

Skill Claude CodeCodex

Retrieve logs from a Kubernetes node — systemd units (journalctl) or files under /var/log. Use when you need node-level evidence: containerd, kubelet, kernel/OOM, or anything the pod's own log cannot show. Three access paths in order: hostscript (SSH), nodescript (debug pod), and localscript against the kubelet log…

scitix/siclaw

Skill Claude CodeCodex

Diagnose pod crash failures (CrashLoopBackOff, OOMKilled, Error, RunContainerError). Checks pod status, events, and previous logs to identify root cause.

scitix/siclaw

Skill Claude CodeCodex

Diagnose pod scheduling failures (Pending, Unschedulable). Checks events, node resources, taints, affinity, and PVC bindings to identify why a pod cannot be scheduled.

scitix/siclaw

Skill Claude CodeCodex

Diagnose PersistentVolumeClaim failures (Pending PVC, StorageClass not found, PV binding issues, capacity mismatch). Checks PVC, PV, StorageClass, and provisioner events to identify why storage is not available.

scitix/siclaw

Skill Claude CodeCodex

Diagnose Kubernetes native ResourceQuota and LimitRange admission rejections (exceeded quota, forbidden by LimitRange, FailedCreate). Checks namespace quotas, current usage, LimitRange constraints, and ReplicaSet events to identify why pods cannot be created. Not applicable to Volcano Queue — use…

scitix/siclaw

Skill Claude CodeCodex

Diagnose Service connectivity issues (empty Endpoints, selector mismatch, port mismatch, no backend pods). Checks Service, Endpoints, and target pods to identify why traffic is not reaching backends.

scitix/siclaw

Skill Claude CodeCodex

Diagnose StatefulSet rollout and scaling failures (ordered update stuck, OnDelete not updating, partition misconfiguration, PVC binding deadlocks). Checks update strategy, pod ordinal progression, PVC bindings, and ordered startup to identify why a StatefulSet is not progressing.

scitix/siclaw

Skill Claude CodeCodex

Diagnose Volcano-managed Pod scheduling issues. Checks Pod status, PodGroup, events, and Queue to identify scheduling failures.

scitix/siclaw

Skill Claude CodeCodex

Gang Scheduling diagnostic guide for Volcano. Use when PodGroup cannot schedule completely, member Pods remain Pending, or minAvailable/minMember constraints are not satisfied.

scitix/siclaw

Skill Claude CodeCodex

Diagnose Volcano Job status and issues. Check Job phases, task statuses, PodGroup associations, and overall job health.

scitix/siclaw

Skill Claude CodeCodex

Query cluster node resources for Volcano scheduling. Check allocatable CPU, memory, GPU, and current usage.
