Recommended Skills
Journey fit
Shopify admin extensions are integration work inside the merchant admin, which is core Build activity once you are implementing the product on a commerce platform. Integrations is the canonical shelf because the skill encodes platform APIs, extension surfaces, and versioned Shopify endpoints—not generic marketing or launch distribution.
How it compares
Use as a Shopify-version-aware build skill, not a generic React component library skill that ignores App Bridge and API dating.
