Skill: Docker image publishing

Goal

Provide a reusable GitHub Actions workflow to build/push multi-arch images to GHCR on tag pushes.

Conventions

Publish on tags v*.
Use native Intel or ARM runners for CI/CD. Don't use QEMU
Use buildx + per-arch digest builds, then merge into a manifest.
Use docker/metadata-action for semver tag derivation.

Files

.github/workflows/docker-publish.yml
.github/workflows/prune-docker-images.yml

Use it

Copy one of these into your project. Installing also returns the manifest and these snippets.

# after Install: the listing is in your workspace's routing pool - a plan picks it for its slot
curl -s -X POST https://api.opensmartroute.ai/api/v1/route -H 'Authorization: Bearer $OSR_API_KEY' -H 'Content-Type: application/json' -d '{"text": "...", "plan": true}'

Manifest

An Open Capability Manifest: the router reads it to know what this does, what it costs and when to pick it.
