What is arn-infra-deploy?

An infrastructure deployment tool that applies infrastructure changes to a selected environment, such as staging or production. It includes checks for environment promotion, costs, safety, and tracking of created resources.

Use it to deploy application infrastructure, promote it between environments, or apply definitions made with infrastructure-as-code tools.

It adds review and safety checks around the step that actually changes live infrastructure, reducing the chance of deploying to the wrong place or exceeding cost limits.

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	$0.00132	$0.03929
Opus 5.5	$0.00053	$0.01572
Sonnet 5.5	$0.00026	$0.00786

Security

Grade A, and why

arn-infra-deploy 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 — 328 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Arness Infra Deploy

Execute infrastructure deployment to a target environment with environment promotion enforcement, CI/CD pipeline awareness, cost gates, safety layers, and post-deployment resource tracking. This skill orchestrates the actual apply/deploy step, producing handoff files with secret references and updating the issue lifecycle.

This skill is expertise-adaptive: beginner users deploy via platform CLI commands (fly deploy, railway up), while intermediate and expert users deploy via IaC tools (tofu apply, pulumi up). All experience levels receive the same safety protections.

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:

Deferred -- if yes, inform the user that infrastructure is deferred and suggest running /arn-infra-assess first. Stop.
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.
Providers -- which cloud providers are configured
Providers config -- path to providers.md for per-provider details and IaC tool overrides
Default IaC tool -- the default IaC tool to use when no per-provider override exists
Environments -- environment names in promotion order
Environments config -- path to environments.md for promotion pipeline and deployment state
Tooling manifest -- path to tooling-manifest.json for tool availability checks
Resource manifest -- path to active-resources.json for resource tracking
Cost threshold -- monthly budget limit for cost gate warnings
Validation ceiling -- maximum validation level before requiring explicit approval
Platform -- for issue label management
Issue tracker -- for issue lifecycle transitions
Infra specs directory -- from ## Arness config, for locating INFRA spec and handoff files (default: .arness/infra-specs)

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.
