Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00161 | $0.01491 |
| Opus 5 | $0.00081 | $0.00745 |
| Sonnet 5 | $0.00032 | $0.00298 |
| Haiku 4.5 | $0.00016 | $0.00149 |
Grade A, and why
nvcf-explore-stack 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 2d 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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
NVCF Explore Stack
Help a user or developer navigate the NVCF self-hosted stack inside the monorepo. Identify what a release is, what installs it, what it depends on, and which subtree owns the chart and the runtime image.
Instructions
This skill is for both NVCF users and NVCF developers. Users use it to understand stack dependencies, deployment order, and CI/CD migration questions. Developers use it to find the owning chart, source subtree, hook, or helmfile stage before making changes.
Use this skill long enough to answer the question, then hand off to the right execution skill. Always cite the source file path so the user can verify.
Required inputs
Read these from the monorepo root.
Authoritative (always read first when answering):
deploy/stacks/self-managed/helmfile.d/00-observability-infrastructure.yaml.gotmpldeploy/stacks/self-managed/helmfile.d/01-dependencies.yaml.gotmpldeploy/stacks/self-managed/helmfile.d/02-core.yaml.gotmpldeploy/stacks/self-managed/helmfile.d/03-observability.yaml.gotmpldeploy/stacks/observability/helmfile.d/01-observability.yaml.gotmpldeploy/stacks/nvcf-compute-plane/helmfile.d/01-dependencies.yaml.gotmpldeploy/stacks/nvcf-compute-plane/helmfile.d/02-nvca.yaml.gotmpl
Chart-level (when the chart is checked into the monorepo):
deploy/helm/<chart>/Chart.yamldeploy/helm/<chart>/values.yaml
Common questions
What deploys X
: Look up release X in the helmfile stage files. Return chart name, version, namespace, and which gotmpl file declares it. If the chart is checked in, also point at deploy/helm/<chart>/.
What does X depend on
: Return the needs: chain for that release plus the stage gate it sits behind (control-plane stages 0 -> 1 -> 2 -> 3, then compute-plane). Include any profile, condition:, or component mode that gates whether X deploys at all.
What hooks run for X
: Read the checked-in chart under deploy/helm/<chart>/ when available. Search its templates/ directory for Helm hook annotations, weights, hook events (pre-install / post-install), images used, and purpose. Cite the chart-relative template file path. If the chart is not checked in, cite its Helmfile chart reference and state that local templates are unavailable.
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-explore-stack is a skill published in the GitHub repository NVIDIA/nvcf (202 stars, last pushed 2d ago), licensed Apache-2.0. It adds 161 tokens to every session and 1,491 once invoked, about $0.0008 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.
