A Claude skill that makes AI assistants actually competent at container

[jcordon5]

I kept hitting a wall using AI assistants with container: because the tool is new, they'd invent a brew install --cask container, fall back to Docker Desktop / Lima / Colima, and miss Mac-specific behavior (per-container IPs, the macOS 15 vs 26 networking differences, the whole container machine concept).

So I distilled the official docs (release 1.x) into an open-source Claude skill — a SKILL.md + references covering the container-vs-container machine decision, networking/volumes, config.toml, and a troubleshooting table.

I benchmarked it on 4 realistic tasks, with vs. without the skill, graded against fixed checks: 22/22 vs 15/22. The gap is entirely on the Mac-specific tasks (e.g. "persistent Linux dev environment" went 1/6 → 6/6, because the baseline did not know container machine exists).
