At a glance
Tools required
apko and access to the package sources and OCI output destination you intend to use
Install & setup
Install apko, create a declarative image configuration that names packages and metadata, then build the OCI image artifact from that config and publish it through your normal registry flow if needed.

Quick brief
apko is a real Chainguard build tool for assembling OCI images from declarative package configurations. Invoke this when you want an agent to construct minimal, auditable images from explicit package lists and metadata, instead of driving a general Dockerfile-based image build.
How it works
What this skill actually does
The scope boundary is declarative image assembly for minimal OCI artifacts. That is narrower than a generic container platform, registry, or image product listing.
