What it does

This skill should be used when the user says "infra help", "arn infra help", "where am I in the pipeline", "what's next for infra", "infra status", "pipeline status", "infra pipeline", "arn-infra-help", "show infra pipeline", "what step am I on for infra", "infra workflow", "infrastructure status", "show infrastructure pipeline", or wants to see their current position in the Arness Infra workflow and get guidance on the next step. This skill detects whether the user is in Quick (interactive) mode or Full Pipeline mode and renders an ASCII diagram with the active stage marked.

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.

16
17Detect the user's current position in the Arness Infra workflow, determine whether they are using Quick mode (interactive skills) or Full Pipeline mode (structured change management), render an ASCII diagram with the active stage marked, and suggest the next command to run. This skill is strictly read-only -- it never modifies files or project state. Supports cross-plugin awareness — detects activity in Arness Spark and Arness Code and provides hints at the bottom of the output.

21## Prerequisites
22
23Read ## Arness from the project's CLAUDE.md. If no ## Arness section exists or Arness Infra fields are missing, inform the user: "Arness Infra is not configured for this project yet. Run /arn-infra-wizard to get started — it will set everything up automatically." Do not proceed without it.
24
25Extract:
26- **Experience level** -- derived from user profile. Read ~/.arness/user-profile.yaml (or .claude/arness-profile.local.md if it exists — project override takes precedence). Apply the experience derivation mapping from ${CLAUDE_PLUGIN_ROOT}/skills/arn-infra-ensure-config/references/experience-derivation.md. If no profile exists, check for legacy Experience level in ## Arness as fallback.
27- **Infra plans directory** -- path to infrastructure change plans (default: .arness/infra-plans)
28- **Infra specs directory** -- path to infrastructure change specs (default: .arness/infra-specs)
29- **Infra docs directory** -- path to infrastructure documentation (default: .arness/infra-docs)
30- **Providers** -- configured providers list
31- **Environments** -- environment promotion pipeline
32- **Deferred** -- whether infrastructure is deferred

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.

≈160
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
6,215
on trigger
The instruction body and 1 supporting file, read only when the skill fires.
3.2%
of a 200k window
Ten skills this size would take about 32% of the window before you open a file.
050k100k150k200k context window

6.4k 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

2 files, 25.5 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • SKILL.md10.2 kB
  • references/pipeline-map.md15.3 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 2 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.

# Arness Infra Help · 6.4k tokens when loaded · macOS, Linux mkdir -p .claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/arness-infra-help/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/arness-infra-help" ] && { [ ! -e .claude/skills/arness-infra-help ] || { mv .claude/skills/arness-infra-help "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/arness-infra-help" .claude/skills/ && echo "Installed .claude/skills/arness-infra-help"
On Windows, or any OS with Node 20+
npx mcprush@latest skill add appsvortex/arness-infra-help

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/arness-infra-help/ 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/arness-infra-help/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/arness-infra-help" ] && { [ ! -e ~/.claude/skills/arness-infra-help ] || { mv ~/.claude/skills/arness-infra-help "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/arness-infra-help" ~/.claude/skills/ && echo "Installed ~/.claude/skills/arness-infra-help" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/arness-infra-help/ 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 arn-infra-help in Gemini CLI, Codex, Copilot and Grok (its own name); Claude Code lists it by the folder name, arness-infra-help.

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

v1.1.0 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.

v1.1.0
  • 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 — v1.1.0 today — and cannot ask for an earlier one. The copy on your disk does not change until you run it again.
