Check before installing. Some of what it can do is expected: a coding skill usually runs build and test commands.

Apptainer: run OCI images as rootless batch jobs with --nv GPU passthrough and digest-pinned SIFs. Use when running a CUDA tool without Docker, podman lacks GPU support, or a pull fills root.

Works with any agent that supports SKILL.md skills.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'apptainer' ] || [ -L ~/.agents/skills/'apptainer' ]; then echo 'A skill folder named apptainer already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/laurigates/claude-plugins' "$d" && git -C "$d" checkout --quiet '16af2dca8c1e706bab01e003bf03a7d19192b346' -- 'tools-plugin/skills/apptainer' && mkdir -p ~/.agents/skills && cp -R "$d"/'tools-plugin/skills/apptainer' ~/.agents/skills/'apptainer' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'apptainer' ~/.claude/skills/'apptainer' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
