docker SKILL.md skillA
docker from nahid-sparktales/agent-dispatcher is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Build container images that are reproducible, small, and safe to run — layer order and what actually caches, multi-stage builds, and what belongs in an image versus what must never be baked into one. Use when writing or reviewing a Dockerfile, when an image build is slow, bloated, or non-deterministic, or when deciding how configuration and secrets reach a container. Not for orchestration, cluster or compose topology, not for CI workflow authoring (github-actions), and not for pipeline stage…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Docker images An image is a build artifact with a filesystem attached. Most of what goes wrong with one is decided by the order of a dozen lines: what got cached, what got copied in that should not have been, and what the container is running as when it starts. A built image is not a running service. "The build succeeded" says the layers assembled, nothing about whether the thing inside starts, serves, or shuts down. ## When this fires A Dockerfile is being written, changed, or reviewed; a build is slow or gives different results on different machines; an image is unexpectedly large; or config and credentials need a route into the container. It does not fire for scheduling, networking between services, or a bug in the application code that happens to be containerized. ## Procedure 1. **Read what exists first** — the Dockerfile, `.dockerignore`, and how the image is actually built (locally, in CI, with what build args). Most "write me a Dockerfile" tasks are really a fix to the one already there, and a second parallel Dockerfile is how two images drift. 2. **Choose the base deliberately and pin it.** Prefer the language's official image or a slim …

How to install
mdr add nahid-sparktales/agent-dispatcher/docker@sha256:f63a3fe231b08ff8The line at the top of this page pins the label git:20260919.a0d4f55, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
