Use for any work in a Spree Commerce 6 project — orienting in the repo (server/, apps/dashboard, apps/storefront), detecting the project flavor (create-spree-app + `spree` CLI vs a classic Rails app), running commands, following Spree conventions (Spree:: namespace, Spree.base_class, Spree.customer_class, current_store scoping, has_status, prefixed IDs, custom fields vs metadata), and finding the right docs.
