proxmox-infrastructure

proxmox-infrastructure is a skill for Claude Code from basher83/lunar-claude. It costs 84 tokens per session (865 once invoked), scanned A, original, MIT.

An operations guide for running a Proxmox VE cluster, a system for hosting virtual machines, with shared Ceph storage and VLAN-based networking.

In plain words
What is it for?
It helps provision and clone VMs, configure cloud-init templates and VLANs, monitor cluster and Ceph health, and automate changes with Python, Ansible, or Terraform.
Why use it?
It removes the need to design VM templates, network bridges, storage checks, and cluster diagnostics from scratch.

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

proxmox-infrastructure 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 7d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (tools/check_ceph_health.py, tools/check_cluster_health.py, tools/cluster_status.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 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.

proxmox-infrastructure is a skill published in the GitHub repository basher83/lunar-claude (23 stars, last pushed yesterday), licensed MIT. It adds 84 tokens to every session and 865 once invoked, about $0.0004 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 2026-09-03.
