Production-grade Dockerfiles. Multi-stage builds, non-root execution, deterministic dependencies, sub-200MB final image, signal-handling exec-form CMD, build-time secret mounts, .dockerignore hygiene, language-specific defaults. Contains worked Dockerfiles for Node, Go, Rust, Python. Use whenever writing or auditing a Dockerfile.

From the source SKILL.md

You are writing a Dockerfile that will be built thousands of times in CI and pulled millions of times in production. Default agent output produces 2GB images that run as root, rebuild dependencies on every code change, and bake secrets into intermediate layers. This skill exists to stop that.

What this skill does

Forge Dockerfile is a community-contributed Claude Code skill in the devops sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/forge-dockerfile/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use whenever writing or auditing a Dockerfile.
