# image-composer-tool OS Availability ## Overview Discover what can be built from `image-templates/` by listing all template metadata. This skill answers: - Which OS families are available - Which distro variants are available - Which architectures are available - Which image types are available - Which exact template files can be built ## When to Use - User asks "what OS can I build?" - User asks for available distro/arch/imageType combinations - User needs to pick a valid template before running a build - User wants a full inventory of all templates under `image-templates/` ## Primary Command ```bash python3 .github/skills/image-composer-list-os/scripts/list-os-templates.py ``` ## Common Filters ```bash # Only Ubuntu templates python3 .github/skills/image-composer-list-os/scripts/list-os-templates.py --os ubuntu # Only x86_64 templates python3 .github/skills/image-composer-list-os/scripts/list-os-templates.py --arch x86_64 # Only raw image templates python3 .github/skills/image-composer-list-os/scripts/list-os-templates.py --image-type raw # Narrow by distro + image type python3 .github/skills/image-composer-list-os/scripts/list-os-templates.py --dist ubuntu24 --image-type raw # Summary only python3 .github/skills/image-composer-list-os/scripts/list-os-templates.py --summary-only ``` ## Output Format The script prints: 1. Summary counts by OS family 2. Detailed table for each template: - template filename - target.os - target.dist - target.arch - target.imageType - metadata.description ## Notes - Source of truth is `image-templates/*.yml` - Templates that fail to parse are reported with warnings - This skill is read-only and does not modify templates
