# CoreWeave Management

Analyze CoreWeave GPU workloads, virtual servers, storage, and Kubernetes resources.

## Phase 1: Discovery

```bash
#!/bin/bash
# CoreWeave uses standard Kubernetes API with their kubeconfig
export KUBECONFIG="${COREWEAVE_KUBECONFIG:-$HOME/.kube/coreweave}"

echo "=== Namespaces ==="
kubectl get namespaces -o json \
  | jq -r '.items[] | "\(.metadata.name)\t\(.status.phase)\t\(.metadata.creationTimestamp[0:10])"' \
  | column -t | head -15

echo ""
echo "=== GPU Workloads ==="
kubectl get pods --all-namespaces -o json \
  | jq -r '.items[] | select(.spec.containers[].resources.limits["nvidia.com/gpu"] != null) | "\(.metadata.namespace)\t\(.metadata.name[0:40])\t\(.status.phase)\t\(.spec.containers[0].resources.limits["nvidia.com/gpu"]) GPU(s)\t\(.spec.nodeName // "pending")"' \
  | column -t | head -20

echo ""
echo "=== Virtual Servers ==="

## Phase 2: Analysis

  | column -t | head -15

echo ""
echo "=== Resource Requests Summary ==="

  | jq '{
    total_gpu_requests: [.items[].spec.containers[].resources.requests["nvidia.com/gpu"] // "0" | tonumber] | add,

  }'

echo ""
echo "=== InferenceService (KServe) ==="

## Safety Rules

- **Read-only**: Only use `kubectl get`, `describe`, and `logs` commands
- **Never create, delete, or scale** workloads without confirmation
- **Kubeconfig**: Never output kubeconfig contents or tokens
- **Secrets**: Never read or output Kubernetes secret values

## Anti-Hallucination Rules

1. **NEVER assume resource names** — always discover via CLI/API in Phase 1 before referencing in Phase 2.
2. **NEVER fabricate metric names or dimensions** — verify against the service documentation or `--help` output.
3. **NEVER mix CLI commands between service versions** — confirm which version/API you are targeting.
4. **ALWAYS use the discovery → verify → analyze chain** — every resource referenced must have been discovered first.
5. **ALWAYS handle empty results gracefully** — an empty response is valid data, not an error to retry.

## Counter-Rationalizations

| Shortcut | Counter | Why |
|----------|---------|-----|
| "I'll skip discovery and check known resources" | Always run Phase 1 discovery first | Resource names change, new resources appear — assumed names cause errors |
| "The user only asked for a quick check" | Follow the full discovery → analysis flow | Quick checks miss critical issues; structured analysis catches silent failures |
| "Default configuration is probably fine" | Audit configuration explicitly | Defaults often leave logging, security, and optimization features disabled |
| "Metrics aren't needed for this" | Always check relevant metrics when available | API/CLI responses show current state; metrics reveal trends and intermittent issues |
| "I don't have access to that" | Try the command and report the actual error | Assumed permission failures prevent useful investigation; actual errors are informative |
