multi-stage-dockerfile skillA
multi-stage-dockerfile is agent-read markdown (skill) from fabioc-aloha/alex_skill_mall: Create optimized multi-stage Dockerfiles for any language or framework.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
Your goal is to help me create efficient multi-stage Dockerfiles that follow best practices, resulting in smaller, more secure container images. ## Multi-Stage Structure - Use a builder stage for compilation, dependency installation, and other build-time operations - Use a separate runtime stage that only includes what's needed to run the application - Copy only the necessary artifacts from the builder stage to the runtime stage - Use meaningful stage names with the `AS` keyword (e.g., `FROM node:18 AS builder`) - Place stages in logical order: dependencies → build → test → runtime ## Base Images - Start with official, minimal base images when possible - Specify exact version tags to ensure reproducible builds (e.g., `python:3.11-slim` not just `python`) - Consider distroless images for runtime stages where appropriate - Use Alpine-based images for smaller footprints when compatible with your application - Ensure the runtime image has the minimal necessary dependencies ## Layer Optimization - Organize commands to maximize layer caching - Place commands that change frequently (like code changes) after commands that change less frequently (like dependency installation) …

How to install
mdr add fabioc-aloha/alex_skill_mall/multi-stage-dockerfile@git:20260728.80a7ab6mdr add fabioc-aloha/alex_skill_mall/multi-stage-dockerfile@sha256:56c9532717b01477Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
