What it does

This skill should be used when the user is choosing between managed and self-hosted services, deciding whether to run Kubernetes or use managed containers, evaluating self-hosted databases vs managed databases, considering self-hosted monitoring or caches, designing for a small team (under 50 engineers), or justifying a self-hosted exception. Covers the operations tax of self-hosting, managed container orchestration over Kubernetes for small teams, managed workflow engines, managed caches and databases, managed monitoring, and the decision framework for when self-hosting is genuinely…

What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.

The skill itself

A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.

9Self-hosting a database, a cache, a workflow engine, or a Kubernetes cluster is not free. It costs patching, backup verification, incident response at 3 AM, capacity planning, version upgrades, security hardening, and monitoring of the monitor. Each self-hosted service is an invisible full-time job. For a team of five engineers shipping a SaaS product, running your own PostgreSQL is the equivalent of hiring a sixth engineer whose entire job is keeping PostgreSQL alive -- except you do not hire that person, so the work falls on everyone, and nobody does it well.

11Managed services trade money for engineering time. For startups and small teams (under 50 engineers), this trade is almost always correct. The cloud bill goes up by hundreds of dollars per month; the engineering team gets back thousands of dollars in reclaimed time. Self-host only when the managed service genuinely cannot meet your requirements -- and document the justification in an ADR.

13## The Operations Tax
14
15Every self-hosted service carries a recurring operations cost that is invisible until something breaks.
16
17| Operations Task | Managed Service | Self-Hosted |
18|-----------------|-----------------|-------------|
19| OS/kernel patching | Provider handles it | You schedule downtime, test, apply |
20| Version upgrades | One-click or automatic | You test, migrate, rollback-plan, execute |
21| Backup & restore | Automated, point-in-time | You configure, verify, test restores quarterly |
22| Scaling | Auto-scaling or single API call | You monitor, forecast, provision, rebalance |
23| High availability | Built-in multi-AZ/region | You design, implement, test failover |
24| Security hardening | Provider hardens, you configure | You harden OS, network, application, and runtime |
25| Monitoring | Built-in metrics and logs | You deploy exporters, configure dashboards, set alerts |

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈170
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
9,830
on trigger
The instruction body and 2 supporting files, read only when the skill fires.
5.0%
of a 200k window
Ten skills this size would take about 50% of the window before you open a file.
050k100k150k200k context window

10k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

No worked example has been published for this skill yet.

The procedure it runs

The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.

What it asks for
Writes filesnot declared
Network accessnot declared

This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

3 files, 40.0 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md14.8 kB
  • examples/managed-container-service.md11.8 kB
  • examples/managed-data-stack.md13.4 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 3 files you can review in full before installing. The MIT licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

Windows PowerShell says 'running scripts is disabled on this system'? Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/every-self-hosted-service-is-a-person-you-didn-t/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/every-self-hosted-service-is-a-person-you-didn-t/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/every-self-hosted-service-is-a-person-you-didn-t" ] && { [ ! -e ~/.claude/skills/every-self-hosted-service-is-a-person-you-didn-t ] || { mv ~/.claude/skills/every-self-hosted-service-is-a-person-you-didn-t "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/every-self-hosted-service-is-a-person-you-didn-t" ~/.claude/skills/ && echo "Installed ~/.claude/skills/every-self-hosted-service-is-a-person-you-didn-t" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/every-self-hosted-service-is-a-person-you-didn-t/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where. It appears as managed-services-over-self-hosted in Gemini CLI, Codex, Copilot and Grok (its own name); Claude Code lists it by the folder name, every-self-hosted-service-is-a-person-you-didn-t.

Which clients pick it up on their own

A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.

Versions

v1.0.0 is what is on the shelf; no release here carries a date. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

v1.0.0
  • No earlier releases have been published to the marketplace.
Pinning

The install command always fetches the release that is current the day you run it — v1.0.0 today — and cannot ask for an earlier one. The copy on your disk does not change until you run it again.
