installing-software

installing-software is a skill for Claude Code from yale-som-hpc/claude-code-marketplace. It costs 71 tokens per session (1,505 once invoked), scanned C, original, Unlicense.

A set of instructions for installing software on the Yale SOM HPC cluster without administrator access. It explains when to use cluster modules, language package managers, user-installed binaries, or Apptainer containers.

In plain words
What is it for?
Use it when installing tools or packages on the cluster, loading software with Lmod, managing Python or R dependencies, handling GLIBC compatibility errors, building software from source, or running Apptainer containers.
Why use it?
It helps avoid failed installations caused by missing permissions, incompatible system libraries, or packages being installed incorrectly across shared cluster jobs.

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 C, and why

installing-software scanned grade C with 2 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 176 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Installing Software

Rule: prefer cluster modules for system software, uv/renv for language packages, and static binaries in ~/.local/bin for user tools.

Modules first

module avail
module spider git
module spider r
module spider cuda
module load git
module load r

Important: Git may require module load git. Do not assume it is in the default PATH.

For Python projects, prefer uv and a project .venv over loading a generic Python module. Use the Python module only when you specifically need cluster-provided Python or a module-provided package.

In reusable shell scripts and Slurm scripts, load required modules explicitly rather than relying on your interactive shell state:

module purge
module load git
module load r

User binaries

Put user-installed command-line tools here:

mkdir -p ~/.local/bin ~/go/bin
export PATH="$HOME/.local/bin:$HOME/go/bin:$PATH"

Prefer statically-linked builds from GitHub releases if available. Inspect "curl to sh" install patterns prior to using those. Common per-user tools:

  • uv — Python project manager (install snippet below).
  • duckdb — CLI for SQL over Parquet/CSV/JSON; not module-loadable on the cluster. See accelerating Python.
  • qsv — fast CSV triage; not module-loadable. Same place.
  • gh — GitHub CLI.
  • jq — JSON on the command line.
  • ripgrep — fast recursive grep.
  • croc, rclone — file transfer (see using the filesystem).

Prefer static or musl binaries

If a GitHub release offers a Linux musl build, prefer it:

x86_64-unknown-linux-musl
x86_64-musl
static-linux-amd64

Why: modern prebuilt binaries often require a newer glibc than the cluster provides. Static/musl builds avoid many GLIBC_2.xx not found errors.

Typical failure:

./tool: /lib64/libc.so.6: version `GLIBC_2.38' not found

Fix: download a musl/static build, use a module, build in Apptainer, or compile on the cluster.

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.

installing-software is a skill published in the GitHub repository yale-som-hpc/claude-code-marketplace (5 stars, last pushed 1mo ago), licensed Unlicense. It adds 71 tokens to every session and 1,505 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
