A first-run setup skill for the Proxmox management plugin, which manages virtual machines and containers on a server. It asks for host and connection details and saves them in a configuration file.

Use it to configure a Proxmox host's IP address, SSH account, web interface URL, and optional API token references before using other management skills.

It creates the connection profile that other Proxmox actions need, while keeping host-specific values out of the plugin's general instructions.

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.

Any agent

npx skills add danielrosehill/Proxmox-Mgmt-Plugin --skill onboard

Clone the repo

git clone --depth 1 https://github.com/danielrosehill/Proxmox-Mgmt-Plugin

Made for: Claude Code.

Or install proxmox-mgmt, the plugin that ships this one along with the rest of its 2 skills.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00108	$0.01284
Opus 5	$0.00054	$0.00642
Sonnet 5	$0.00022	$0.00257
Haiku 4.5	$0.00011	$0.00128

Security

Grade A, and why

onboard 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 9d 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 — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

proxmox-mgmt: onboard

Establish the persistent connection profile for a Proxmox VE host. The same plugin install can serve multiple Proxmox environments — only the values in config.json are environment-specific. No host details should ever be hard-coded into other skills in this plugin.

Workspace resolution

Resolve the plugin's data directory as $CLAUDE_USER_DATA/proxmox-mgmt/ if CLAUDE_USER_DATA is set; otherwise $XDG_DATA_HOME/claude-plugins/proxmox-mgmt/ if XDG_DATA_HOME is set; otherwise ~/.local/share/claude-plugins/proxmox-mgmt/. Create the directory if it doesn't exist. See the canonical convention in the claude-rudder:plugin-data-storage skill.

Shell form:

PLUGIN_DATA_DIR="${CLAUDE_USER_DATA:-${XDG_DATA_HOME:-$HOME/.local/share}/claude-plugins}/proxmox-mgmt"
mkdir -p "$PLUGIN_DATA_DIR"

The config file is $PLUGIN_DATA_DIR/config.json.

When to use

User says "set up proxmox", "onboard proxmox", "configure proxmox plugin".
Any other proxmox-mgmt skill finds no config.json at the resolved path — offer to run onboarding first.
The user changes hosts, IPs, or credentials.

Procedure

Load existing config from $PLUGIN_DATA_DIR/config.json if present. Show the current values back. Offer Update vs Replace vs Cancel.

Interview the user. Ask each question; default sensibly when the user just hits enter:

Field	Prompt	Notes
`host`	"What's the LAN address of your Proxmox host?"	No default — user must answer. Hostname or IP.
`ssh_user`	"SSH username?"	Default: `root`. Proxmox typically uses root for management.
`ssh_port`	"SSH port?"	Default: `22`.
`ssh_key_path`	"Path to the SSH private key (or leave blank for default agent)?"	Optional. Expand `~`.
`web_url`	"Proxmox web UI URL?"	Default: `https://<host>:8006`.
`node_name`	"Proxmox node name (run `hostname` on the host if unsure)?"	Used by API calls. Default: derived from `host`.
`api_enabled`	"Use the Proxmox API? (y/n)"	If yes, ask for the next two.
`api_token_id`	"API token ID (e.g. `root@pam!claude`)?"	Stored as plain text — it's an identifier, not a secret.
`api_token_secret_ref`	"Where is the API token secret stored? (1Password ref / env var name / file path)"	Reference only.
`verify_tls`	"Verify TLS on the Proxmox web/API URL? (y/n)"	Default: `n` (most homelab Proxmox hosts use self-signed certs).
`notes`	"Any free-text notes about this host?"	Optional (e.g. GPU passthrough, RAID 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.

onboard is a skill published in the GitHub repository danielrosehill/Proxmox-Mgmt-Plugin (10 stars, last pushed 4mo ago), licensed MIT. It adds 108 tokens to every session and 1,284 once invoked, about $0.0005 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 2026-08-31.
