Opt-in advanced Docker security hardening beyond the docker-setup baseline — LAN containment with DNS policy, resource bounds with kernel-hygiene sysctls, and a boot-time plugin install audit log. Applied as a reversible docker-compose overlay (does not touch the base compose file) and verified against the live container. Run after /docker-setup; requires bridge networking.
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/'docker-security' ] || [ -L ~/.agents/skills/'docker-security' ]; then echo 'A skill folder named docker-security already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/gtapps/hermitd' "$d" && git -C "$d" checkout --quiet 'c2d971ab801daa0725f1554f92e405e62f76a3e8' -- 'plugins/hermitd/skills/docker-security' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/hermitd/skills/docker-security' ~/.agents/skills/'docker-security' && 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/'docker-security' ~/.claude/skills/'docker-security' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
