Route a request to install a tool, binary, package, env var, persistent directory, side service, or personal/third-party skill in the hermit Docker container to the first channel that can carry it. Apt packages go in the Dockerfile operator block; boot-time shell work goes in docker-entrypoint.hermit-local.sh; compose and Dockerfile only when nothing else fits. Activates on messages like "install skills in the container", "install gog in the container", "add an apt package", "download a binary …

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'docker-customize' ] || [ -L ~/.agents/skills/'docker-customize' ]; then echo 'A skill folder named docker-customize 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 "$d" checkout --quiet 'c2d971ab801daa0725f1554f92e405e62f76a3e8' -- 'plugins/hermitd/skills/docker-customize' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/hermitd/skills/docker-customize' ~/.agents/skills/'docker-customize' && 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-customize' ~/.claude/skills/'docker-customize' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
