Host a service on a stable public HTTPS URL straight from a cloud VM — start your app, run one command, get https://<box>-<port>.on.ascii.dev with managed TLS and token-gating. Supports bring-your-own domain and raw TCP/UDP via a dedicated IPv4. Use to host a web app, API, demo, or webhook endpoint without DNS or certificate setup.

  • Pipes a download into a shell
  • Reads credentials

The file

We split this skill into the rules it gives an agent

1 rule. About 0 are common, 1 is distinctive, and 0 are very specific to this project.

  • ≈0

    Many files like this have a rule of this kind.

  • ≈1

    Distinctive · estimate

    This author's own choices. Worth a look.

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  1. Distinctive:

    Use this to put a running service on the public internet from inside a Box: a web app, an API, a demo, or a long-lived endpoint.

    line 8

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Public URL hosting (Box)

Use this to put a running service on the public internet from inside a Box: a web app, an API, a demo, or a long-lived endpoint. Box handles TLS, routing, and auth — no DNS, no certificates, no separate platform.

Recipe

box_id="$(box new --no-auto-stop --json | jq -r 'select(.event == "ready") | .id')"
box ssh "$box_id" -- bash -s < ./deploy.sh                 # build + start app on 0.0.0.0:8080
box ssh "$box_id" -- "host 8080 --public --title 'my app'"
box ssh "$box_id" -- "host url 8080"                        # https://<box>-8080.on.ascii.dev

host URLs are token-gated by default; --public makes them open. A dedicated IPv4 + full TCP/UDP means you can also point your own domain or host non-HTTP services.

Why Box

  • Zero infra — TLS + subdomain + auth managed for you.
  • Stays up — --no-auto-stop keeps the host alive 24-7; persists across resume.
  • Cheap — per-second billing, ~10× cheaper than typical sandbox/host providers.

Prereqs

curl -fsSL https://box.ascii.dev/install | sh, then box login "$BOX_API_KEY" --json.

Limits

EU-only; 100 active VMs soft cap. For multi-region CDN-grade hosting, use a dedicated host; Box is best for single-VM services, previews, and demos.

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
