What it does
Vast Host Install is an agent skill from jjziets/vasttools. Prepare, install and commission NVIDIA GPU hosts for Vast.ai using host-specific safety gates, XFS storage checks, cgroup/runtime testing and optional VM qualification. Use for Vast host installation or readiness work, not renter-instance setup.
Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including reference files (for example `agents/openai.yaml`, `references/cgroups.md` and `references/evidence.md`).
It sits in DevOps & Cloud. It works with NVIDIA AI Platform and Docker. The repository describes itself as: My swiftsknife for vast.ai service.

Example prompts
- “/vast-host-install”

What it can do on your machine
Read from SKILL.md and the folder at commit 27529eb. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
discord.gg
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Vast Host Install loads about 2.1k tokens when it runs, and up to ~17k if it reads all its reference files. Until then it costs about 66 tokens; SKILL.md has 1,051 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,051 words (~2,078 tokens).
“Produce a reproducible host build with observed acceptance results. Support preparation, authorized installation, and commissioning. Begin with read-only discovery when the target or change scope is unclear. A request to write or publish this runbook is not permission to operate…”
