What is convert-to-apple-container?

A conversion from Docker to Apple Container, Apple's container runtime for macOS. It changes how ClaudeClaw starts containers, mounts folders, checks status, and builds images.

It helps switch the container runtime, update mount commands and startup checks, and adapt the container entrypoint for Apple's directory-mount rules.

It lets macOS users run ClaudeClaw with Apple Container instead of Docker while retaining the existing security checks and interfaces. Apple Container must be installed.

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.

Clone the repo

git clone --depth 1 https://github.com/sbusso/claudeclaw

npx agentmods add skills/sbusso/claudeclaw/convert-to-apple-container

Made for: Claude Code.

Or install claudeclaw, the plugin that ships this one along with the rest of its 27 skills.

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	$0.00068	$0.01363
Opus 5	$0.00034	$0.00681
Sonnet 5	$0.00014	$0.00273
Haiku 4.5	$0.00007	$0.00136

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 10d 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.

Recursive force deletehighDestructive command

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 ClaudeClaw'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: docker → container
Mount syntax: -v path:path:ro → --mount type=bind,source=...,target=...,readonly
Startup check: docker info → container system status (with auto-start)
Orphan detection: docker ps --filter → container ls --format json
Build script default: docker → container
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:

Download from https://github.com/apple/container/releases
Install the .pkg file
Verify: container --version

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

Phase 1: Pre-flight

Check if already applied

grep "CONTAINER_RUNTIME_BIN" src/orchestrator/container-runtime.ts

If it already shows 'container', the runtime is already Apple Container. Skip to Phase 3.

Phase 2: Apply Code Changes

Ensure upstream remote

git remote -v

If upstream is missing, add it:

git remote add upstream https://github.com/sbusso/claudeclaw.git

Merge the skill branch

git fetch upstream skill/apple-container
git merge upstream/skill/apple-container

This merges in:

src/orchestrator/container-runtime.ts — Apple Container implementation (replaces Docker)
src/container-runtime.test.ts — Apple Container-specific tests
src/orchestrator/container-runner.ts — .env shadow mount fix and privilege dropping
src/runtimes/docker/Dockerfile — entrypoint that shadows .env via mount --bind
src/runtimes/docker/build.sh — default runtime set to container

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.

convert-to-apple-container is a skill published in the GitHub repository sbusso/claudeclaw (192 stars, last pushed 28d ago), licensed MIT. It adds 68 tokens to every session and 1,363 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 2026-08-30.
