environment-setup is a skill for Claude Code, Codex from Katagiri-Hoshino-Lab/VibeCodeHPC. It costs 34 tokens per session (249 once invoked), scanned A, original, MIT.

Guidance for installing command-line tools and dependencies when setting up VibeCodeHPC on a new computer, container, or supercomputer. A command-line tool is a program controlled by typed terminal commands.

In plain words
What is it for?

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

environment-setup 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 10d 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.

What it actually says

Environment Setup

Decision Flow

  1. Check available tools: which node npm cargo python3 module
  2. Check constraints: container restrictions, network access, admin privileges
  3. Select CLI based on environment (see references/)
  4. Install and authenticate

CLI Selection Guide

Constraint Recommended CLI
No npm/node Codex (Rust binary)
No network (air-gapped) vibe-local (Ollama, pre-downloaded models)
Supercomputer (batch jobs) Claude Code or Codex
Container (no job scheduler) Any, but verify batch job access
Free tier only OpenCode (Nemotron, keyless)

Files

What ships with it

3 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.
