Shopify Polaris Customer Account Extensions

This one helps you build custom UI extensions for Shopify customer account pages using their Polaris component library. You get access to 20+ extension targets across order status, profile, and order index pages, plus a full set of web components like forms, buttons, banners, and even maps. The workflow is strict: you must search docs, write code, then validate with specific flags including your extension target before returning anything. It enforces version 2026-01 and won't let you skip validation, which is honestly helpful since it catches issues like HTML comments that break the validator. Most useful when you need to add merchant-installable features to customer accounts without fighting the docs yourself.
