container is a skill for Claude Code from vinnie357/claude-skills. It costs 57 tokens per session (4,032 once invoked), scanned A, original, MIT.

A guide for using Apple Container, a macOS tool that runs Linux containers as lightweight virtual machines on Apple silicon Macs.

In plain words
What is it for?
Use it to build and run OCI-compatible containers, manage container machines, and configure container-based services on supported Macs.
Why use it?
It explains the system requirements, container management, configuration, networking, storage, and service setup needed to run containers.

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

container 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 9d ago.

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.

Apple Container CLI

This skill activates when working with Apple Container for running Linux containers natively on Apple silicon Macs.

What is Apple Container?

Apple Container is a macOS-native tool for running Linux containers as lightweight virtual machines on Apple silicon:

  • Swift-based: Built on Apple's Virtualization.framework
  • OCI-compatible: Produces and runs standard OCI container images
  • Apple silicon only: Requires Apple silicon Mac (M1 or later)
  • Stable 1.0: Currently at version 1.0.0 (released 2026-06-09); 0.x minor releases carried frequent breaking changes — see Version Differences below when upgrading
  • Lightweight VMs: Each container runs as a lightweight Linux VM

Prerequisites

  • macOS 26 or later (Tahoe)
  • Apple silicon Mac (M1, M2, M3, M4 series)
  • Install via signed .pkg from GitHub releases

System Management

Manage the container system service (start, stop, status, version, logs, disk usage) and its TOML configuration file. Full command list, flag tables, and the TOML config detail: references/command-reference.md.

⚠ BREAKING — 1.0.0: A TOML configuration file at ~/.config/container/config.toml replaces the UserDefaults-backed system properties. container system property get, set, and clear are REMOVED — edit the TOML file, then restart the service (container system stop && container system start).

Container Lifecycle

Run, manage, and export containers (run, list/ls, start, stop, kill, delete/rm, exec, logs, inspect, cp, stats, prune, export, create). Full flag tables and worked examples: references/command-reference.md.

Two corrections worth keeping in view: a custom MAC address is set via --network <name>,mac=XX:XX:XX:XX:XX:XX on container run — there is no separate --mac-address flag. container export produces a filesystem tar only (-o/--output); it does not create or tag an image, and there is no -t/--tag flag.

What ships with it

18 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.

Changes

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.

container is a skill published in the GitHub repository vinnie357/claude-skills (25 stars, last pushed 2d ago), licensed MIT. It adds 57 tokens to every session and 4,032 once invoked, about $0.0003 per session on Opus 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 2026-08-30.
