nvcf-self-managed-prerequisite

nvcf-self-managed-prerequisite is a skill for Claude Code, Codex from NVIDIA/nvcf. It costs 195 tokens per session (2,444 once invoked), scanned A, original, Apache-2.0.

A setup guide for the prerequisites needed by the NVCA operator and compute-plane stack, a system for managing NVIDIA compute resources. It covers nvcf-cli, KAI Scheduler, and the SMB CSI driver.

In plain words
What is it for?
Use it before running nvcf-nvca-install or setting up self-managed compute resources, scheduling, and shared Samba storage.
Why use it?
The installation can fail when these tools or cluster components are missing. The guide explains what each prerequisite does and when it is needed.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nvcf-self-managed-prerequisite scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 178 lines — stays where its author put it; the contents beside it link to each section on GitHub.

NVCA prerequisites — KAI Scheduler + SMB CSI

One operator tool plus two cluster-level components the NVCA operator / compute plane depends on. Satisfy all three before running nvcf-nvca-install.

Prereq Why it is needed Detail
nvcf-cli The compute-plane stack's make register-cluster (and install/apply/sync, which abort without the registration values it writes) shells out to nvcf-cli. The shipped stack defaults to building it from a sibling ../cli checkout that the release does not include, so a green-field repo fails with ensure-nvcf-cli / "Registration values not found". See Step 0b below
KAI Scheduler selfManaged.featureGateValues includes KAIScheduler; NVCA polls Queue CRs and refuses to become healthy until their quotas are -1. Skip the standalone helm step below when addons.kaiScheduler.enabled is set in nvcf-compute-plane (required when enabling Grove or Dynamo). references/kai-scheduler.md
SMB CSI driver (smb.csi.k8s.io) NVCA's selfManaged.sharedStorage runs Samba sidecar pods that export file shares; the resulting PVCs need this CSI driver to bind references/smb-csi.md

The KAI Scheduler and SMB CSI installs are cloud-neutral helm commands pinned to NVCF-validated versions. These are upstream third-party charts (not NVCF images), so they are not in manifest.yaml; the per-component reference docs carry the current pin and link the NVCF docs version table. nvcf-cli is an operator workstation tool, not an in-cluster install.

Prerequisites

  • A running Kubernetes cluster (any cloud — AKS, EKS, GKE, k3d, MicroK8s) with kubectl configured and admin access.
  • helm >= 3.12 and < 4. Helm 4 is NOT supported (matches nvcf-self-managed-stack/README.md). On Helm 4 the KAI install below hangs silently for many minutes — Helm 4 runs the chart's pre-install crd-manager hook through a before-hook-creation delete and then waits --timeout per already-absent hook resource, so the release sits in pending-install with no pods and never errors cleanly. Use Helm 3.x.
  • Cluster has CPU headroom on a general-purpose node pool for KAI's 7 pods.

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

nvcf-self-managed-prerequisite is a skill published in the GitHub repository NVIDIA/nvcf (202 stars, last pushed 4d ago), licensed Apache-2.0. It adds 195 tokens to every session and 2,444 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
