labor.fun: Skill for Claude Code

.claude/skills/convert-to-apple-container/SKILL.md

convert-to-apple-container is a skill for Claude Code from BreadchainCoop/labor.fun. It costs 68 tokens per session (1,668 once invoked), scanned D, a copy of convert-to-apple-container, MIT.

A migration guide for replacing Docker with Apple Container, Apple's macOS-native container runtime.

In plain words
What is it for?
Use it to update container commands, bind mounts, build-script defaults, startup checks, orphan detection, and the Dockerfile entrypoint for macOS.
Why use it?
It helps adapt commands and startup checks when moving to Apple Container, including differences in mounts, container listing, and container privileges.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: names the AskUserQuestion tool.

This is BreadchainCoop/labor.fun's own configuration. It tells Claude Code how to work on labor.fun itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything labor.fun configures →

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

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 D, and why

convert-to-apple-container scanned grade D with 3 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 7d 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

echo "block in on en0 proto tcp to any port 3001" | sudo pfctl -ef -

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 Breadbrich Engels'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
  • 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.

Phase 1: Pre-flight

Check if already applied

grep "CONTAINER_RUNTIME_BIN" src/container-runtime.ts

If it already shows 'container', the runtime is already Apple Container. Skip to Phase 4.

Phase 2: Apply Code Changes

Ensure upstream remote

git remote -v

If upstream is missing, add it:

git remote add upstream https://github.com/qwibitai/salem.git

Merge the skill branch

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

This merges in:

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

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.

convert-to-apple-container is a skill published in the GitHub repository BreadchainCoop/labor.fun (2 stars, last pushed 6d ago), licensed MIT. It adds 68 tokens to every session and 1,668 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it D with 3 findings (asks for root, recursive force delete, makes network calls). It is 86% identical to convert-to-apple-container, differing in 76 lines, and is treated as a copy.
