Get a clean, reproducible ephemeral environment for CI and testing — a fresh root Ubuntu VM with every major toolchain and Docker preinstalled, your GitHub repo auto-cloned in, and the whole thing thrown away after. Per-second billing makes each run cost cents. Use to run tests, reproduce a bug, or validate a build in a pristine environment without polluting the host.
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
# Ephemeral CI / test environment (Box) Use this when you need a **clean, throwaway environment** to test a repo, run a CI job, or reproduce a bug — identical every time, with nothing left behind. Every run starts from a fresh VM with all toolchains preinstalled, so there's no "works on my machine" drift. ## Why Box - **Pristine + reproducible** — fresh VM per run; no leftover state. - **Batteries included** — Docker + Node/Python/Go/Rust/Java/etc. already there; repo auto-clones in. - **Cheap per run** — $0.036/h billed per second; a test run costs cents of VM time, and you `box delete` after. On the $20 plan, 200 starts a day are included; each extra start costs $0.03-$0.07. ## Prereqs `curl -fsSL https://box.ascii.dev/install | sh`, then `box login "$BOX_API_KEY" --json`. (Select the repo to auto-clone in the dashboard, or clone it in setup.) ## Recipe ```bash box_id="$(box new --json | jq -r 'select(.event == "ready") | .id')" trap 'box delete "$box_id" --json' EXIT box ssh "$box_id" -- "cd /project && npm ci && npm test" box ssh "$box_id" -- "cat /project/junit.xml" > junit.xml # pull results back ``` ## Limits …

How to install
mdr add ariana-dot-dev/cloud-sandbox-vm-skills/ephemeral-ci-environment@sha256:2b8acd882ced7e0dThe line at the top of this page pins the label git:20261109.2f1d005, 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.
