Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00127 | $0.02741 |
| Opus 5.5 | $0.00051 | $0.01096 |
| Sonnet 5.5 | $0.00025 | $0.00548 |
| Haiku 4.5 | $0.00013 | $0.00274 |
Grade A, and why
arn-infra-containerize 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 — 276 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Arness Infra Containerize
Generate production-ready Dockerfiles, docker-compose configurations, and .dockerignore files for the application. This skill produces security-audited, multi-stage container configurations adapted to the application's technology stack and topology.
This skill reads the application context (codebase patterns, architecture, technology stack) based on the project topology, invokes the arn-infra-specialist agent for container configuration generation, and the arn-infra-security-auditor agent for security review. All generated files are presented for user approval before being written.
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. Containerization is not available until infrastructure is fully configured. Run /arn-infra-assess to un-defer." Stop.
Extract:
- Project topology -- how to resolve the application project (monorepo, separate-repo, infra-only)
- Application path -- path to the application project root
- Experience level -- derived from user profile. Read
~/.arness/user-profile.yaml(or.claude/arness-profile.local.mdif 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 legacyExperience levelin## Arnessas fallback. - Providers -- informs container registry selection and platform-specific optimizations
- Tooling manifest -- path to check for Docker/container tools availability
Workflow
Step 1: Resolve Application Context
Resolve the application project based on topology to understand the technology stack, services, and dependencies.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

arn-infra-containerize is a skill published in the GitHub repository AppsVortex/arness (33 stars, last pushed yesterday), licensed MIT. It adds 127 tokens to every session and 2,741 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-25.
