arn-infra-cleanup

arn-infra-cleanup is a skill for Claude Code from AppsVortex/arness. It costs 147 tokens per session (2,960 once invoked), scanned A, original, MIT.

An infrastructure cleanup tool that finds expired temporary cloud resources using configured time limits. It shows what would be removed and waits for confirmation before destroying anything.

In plain words
What is it for?
Use it to check and remove expired development environments, deployments, and other short-lived infrastructure.
Why use it?
It helps prevent forgotten temporary environments from continuing to use cloud resources and incur costs, without deleting resources automatically.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: mentions CLAUDE.md; names the AskUserQuestion tool.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

arn-infra-cleanup 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 — 301 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Arness Infra Cleanup

Check for expired ephemeral infrastructure resources across three TTL sources (issue tracker, TTL registry, resource manifest) and destroy them with user confirmation. Supports periodic monitoring via /loop for session-duration TTL enforcement.

This skill never auto-destroys resources. Every destruction requires explicit user confirmation with a summary of what will be destroyed and its associated cost.

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.

Check the Deferred field. If Deferred: yes, inform the user: "Infrastructure is in deferred mode. Cleanup is not available until infrastructure is fully configured. Run /arn-infra-assess to un-defer." Stop.

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.
  • Providers -- which cloud providers are configured
  • Providers config -- path to providers.md
  • Default IaC tool -- for determining destroy commands
  • Environments -- environment names in promotion order
  • Environments config -- path to environments.md for per-environment deployment state
  • Resource manifest -- path to active-resources.json for resource inventory
  • Reference overrides -- path to local reference override directory (for evolving reference reads)
  • Platform -- for issue tracker access
  • Issue tracker -- for reading cleanup issues and updating labels
  • Tooling manifest -- path to tooling-manifest.json for available CLIs

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.
