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 — per-second billing; a test run costs cents, and you box delete after.

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.)
