Fine to try. Some of what it can do is expected: a devops skill usually runs commands, installs tools and uses cloud credentials.

Use this skill when writing, reviewing, or optimizing Dockerfiles, even if the user just says their image is too large, their build is slow, or they need to harden a container for production. Covers multi-stage builds, layer caching, .dockerignore, non-root users, and image size optimization.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

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

if [ -e ~/.agents/skills/'docker-build-strategies' ] || [ -L ~/.agents/skills/'docker-build-strategies' ]; then echo 'A skill folder named docker-build-strategies already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/docker/skills' "$d" && git -C "$d" checkout --quiet '3b6fe59c63532138756dae8bea1f62d40b464b62' -- 'skills/docker-build-strategies' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/docker-build-strategies' ~/.agents/skills/'docker-build-strategies' && 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-build-strategies' ~/.claude/skills/'docker-build-strategies' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
