Run a heavy suite, build or eval on an ephemeral 16-vCPU Ubicloud VM: TTL-named VMs, a reaper, quota preflight and a hang watchdog. (gstack).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<!-- AUTO-GENERATED from SKILL.md.tmpl — do not edit directly --> <!-- Regenerate: bun run gen:skill-docs --> # /ubicloud — Ephemeral VMs for heavy runs ## Shared preamble (load first) This skill follows gstack shared preamble `4e82fa4c839f` (AskUserQuestion format, voice, writing, completeness and completion rules). If your Read of that file, headed by this id, is still in context, do not read it again; otherwise Read `~/.claude/skills/gstack/ubicloud/sections/preamble.md` in full before the command below.

How to install
mdr add garrytan/gstack/ubicloud@sha256:7532c04fa0829419The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
