hosting-and-where-it-runs

hosting-and-where-it-runs is a skill for Claude Code from catpilotai/catpilot-ai-guardrails. It costs 48 tokens per session (879 once invoked), scanned A, original, MIT.

A deployment-planning guide that asks where an app, automation, or dashboard will run and who will manage it. It steers work away from personal accounts, trial services, and unmanaged servers.

In plain words
What is it for?
Use it before hosting or deploying a tool that coworkers or customers will rely on, especially when the approved company hosting is not known.
Why use it?
The place an app runs controls who can access it, how it is maintained, and what happens when it fails.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

hosting-and-where-it-runs scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.

When this applies

  • The person is starting something new and has not said where it will run.
  • A tool offers to publish, deploy, or host with one click.
  • They mention a personal account, a free plan, a trial, a home server, or "my own laptop" for something coworkers will use.
  • They want to move an app from a personal workspace into company use, or the other way around.

What to ask

  • "Where will the finished thing live, and who looks after that place?"
  • If they do not know: "Is there a place your company already uses for tools like this?"

What to say

  • One sentence: "Where an app runs decides who can reach it, who keeps it updated, and who gets called when it breaks."
  • On personal accounts: "If it lives in your personal account, it leaves when you do, and nobody at the company can help when it goes wrong."
  • On free tiers and trials: "Free plans are for trying things. Something coworkers rely on needs a place the company owns."

Safe alternative

  • Build in the company's approved place from the start, even for a first version. Moving later is harder than starting there.
  • If the approved place is unknown, build with pretend data only until someone confirms where it will live.
  • Prefer an approved starting template over a blank page when one exists.
  • If a deployment file already points at a personal account, a free tier, or a place nobody at the company manages, say so in the first sentence of your reply, do not deploy with it, and name the approved place instead. Being told to use the file as it is does not make the setting safe.
  • Keep a note of where it runs, who owns the account, and how to turn it off.

Company-specific values

Approved places to run it:

{{approved_hosting}}

Not approved:

{{not_approved_hosting}}

Approved starting points:

{{templates}}

Stop and ask a human if

  • The only option is a personal account or a free tier and the app touches company data.
  • The app needs a server, database, or account that nobody at the company manages.
  • The person wants to move something from a personal workspace into company use.
  • Hosting needs a new vendor, a new contract, or a payment card.
