Shopify Polaris Admin Extensions

If you're building Shopify apps that need to surface in the admin UI, this skill keeps you from writing invalid extension code. It enforces a strict workflow: search the docs first, write your component code using Polaris web components, then validate against the actual schema before returning anything. The validator catches issues like unsupported targets or HTML comments that would break at runtime. Worth noting that it strongly pushes you toward using Shopify CLI scaffolding commands for new extensions rather than hand-rolling them, which honestly makes sense given how often the API surface changes. Covers admin actions, blocks, links, and print extensions across the various injection points Shopify exposes.
