convert-to-apple-container

convert-to-apple-container is a skill for Claude Code from sliamh11/Deus. It costs 68 tokens per session (1,322 once invoked), scanned C, original, MIT.

A migration guide for switching a macOS agent system from Docker to Apple Container, Apple's native container runtime.

In plain words
What is it for?
Use it when setting up Deus on macOS with Apple Container instead of Docker and when verifying the converted build and cleanup behavior.
Why use it?
It updates runtime commands and mount handling while preserving safeguards that prevent one installation from stopping another installation's containers.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./container/build.sh.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 C, and why

convert-to-apple-container scanned grade C with 1 finding 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 5d 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Convert to Apple Container

This skill switches Deus's container runtime from Docker to Apple Container (macOS-only). It uses the skills engine for deterministic code changes, then walks through verification.

What this changes:

  • Container runtime binary: dockercontainer
  • Mount syntax: -v path:path:ro--mount type=bind,source=...,target=...,readonly
  • Startup check: docker infocontainer system status (with auto-start)
  • Orphan detection: docker ps --filtercontainer ls --format json
    • Preserve the instance-suffix scoping (LIA-491). cleanupOrphans() only stops containers whose name ends in this install's -i<8hex> stamp; names without a stamp are warned about, never stopped. Dropping that partition during the port silently restores the old host-wide sweep, in which a second daemon kills the first's live containers. The stamp is a plain name suffix, so it survives any listing format — only the parsing needs porting.
  • Build script default: dockercontainer
  • Dockerfile entrypoint: .env shadowing via mount --bind inside the container (Apple Container only supports directory mounts, not file mounts like Docker's /dev/null overlay)
  • Container runner: main-group containers start as root for mount --bind, then drop privileges via setpriv

What stays the same:

  • Mount security/allowlist validation
  • All exported interfaces and IPC protocol
  • Non-main container behavior (still uses --user flag)
  • All other functionality

Prerequisites

Verify Apple Container is installed:

container --version && echo "Apple Container ready" || echo "Install Apple Container first"

If not installed:

Apple Container requires macOS. It does not work on Linux.

convert-to-apple-container is a skill published in the GitHub repository sliamh11/Deus (51 stars, last pushed 3d ago), licensed MIT. It adds 68 tokens to every session and 1,322 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
