What is arn-infra-help?

A read-only status guide for an infrastructure workflow. It shows which stage the project is in and suggests the next command, without changing files or project state.

It reports the active infrastructure stage, distinguishes interactive from structured workflow modes, displays a simple workflow diagram, and recommends what to run next.

It removes the need to remember a multi-step infrastructure process or inspect several files to find the current position. It can also point out related activity in other Arness workflows.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00133	$0.02260
Opus 5.5	$0.00053	$0.00904
Sonnet 5.5	$0.00027	$0.00452
Haiku 4.5	$0.00013	$0.00226

Security

Grade A, and why

arn-infra-help 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 yesterday.

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 — 165 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Arness Infra Help

Detect 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.

Allowed tools: Read, Glob, Grep only. This skill MUST NOT use Write, Edit, Bash, or Task tools. This skill MUST NOT invoke any agents.

Prerequisites

Read ## 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.

Extract:

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.
Infra plans directory -- path to infrastructure change plans (default: .arness/infra-plans)
Infra specs directory -- path to infrastructure change specs (default: .arness/infra-specs)
Infra docs directory -- path to infrastructure documentation (default: .arness/infra-docs)
Providers -- configured providers list
Environments -- environment promotion pipeline
Deferred -- whether infrastructure is deferred

If any of the infra-specific directory fields are missing, use defaults:

Infra plans directory defaults to .arness/infra-plans
Infra specs directory defaults to .arness/infra-specs
Infra docs directory defaults to .arness/infra-docs

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
