setup-cluster

setup-cluster is a skill for Claude Code, Codex from Zayne-sprague/Dr-Claude-Code. It costs 71 tokens per session (2,994 once invoked), scanned A, original, MIT.

A guided setup process for connecting a new computing cluster to RACA. A cluster is a group of machines used for shared computing, such as a university HPC system, rented cloud GPUs, or a local GPU server.

In plain words
What is it for?
Use it when adding a SLURM system, configuring RunPod, or connecting a local GPU machine. It records the cluster settings in .raca/clusters.yaml.
Why use it?
It turns the connection steps into a checked workflow and verifies that the selected cluster can be reached.

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

setup-cluster scanned grade A with 1 finding 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 3d 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.

GPU Memory Reference Table

Use this when estimating GPU requirements:

GPU VRAM Notes
H200 141 GB Best for 70B+ models
H100 SXM 80 GB Flagship datacenter GPU
H100 PCIe 80 GB Slightly lower bandwidth than SXM
A100 SXM 80 GB Common in academic clusters
A100 PCIe 80 GB Common in academic clusters
GH200 96 GB Grace Hopper — CPU+GPU unified mem
L40S 48 GB Strong for inference
A6000 48 GB Workstation GPU
V100 32 GB Older; common in legacy clusters
RTX 4090 24 GB Consumer; great for local dev
RTX 3090 24 GB Consumer; older
RTX 4080 16 GB Consumer mid-range
T4 16 GB Common in cloud / budget clusters
RTX 3080 10 GB Consumer entry
RTX 4070 12 GB Consumer mid-range

Phase 0: Identify Cluster Type

Ask the user:

"What type of cluster are you setting up?

  1. SLURM (university HPC, national lab, etc.)
  2. RunPod (cloud GPU rental)
  3. Local machine (workstation or server you control directly)"

Route to the appropriate phase based on their answer.


Phase 1a: SLURM Cluster Setup

Step 1.1 — Gather connection info

FIRST: Check ~/.ssh/config for existing aliases.

cat ~/.ssh/config 2>/dev/null

If the user's cluster name already appears as a Host entry in their SSH config, you already have the hostname, user, port, and key. Tell the user: "I found <name> in your SSH config — using hostname <hostname>, user <user>." Use those values directly.

Hostname validation: A valid SSH hostname looks like:

  • A FQDN: login.torch.hpc.nyu.edu, frontera.tacc.utexas.edu
  • An IP: 192.168.1.100
  • An SSH config alias: a short name that appears as Host <name> in ~/.ssh/config

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.
