What problem does it solve? Customizing an Openfront UIKit storefront without understanding the actual source architecture leads to broken checkout flows, unauthorized GraphQL calls, and duplicated backend logic. This Skill guides a structured process of source orientation, user interviews, and contract inspection before any code changes. ## Core Features & Use Cases - Source Architecture Orientation: Maps where behavior lives across features/storefront, app/** routes, Keystone models, and schema.graphql before proposing changes. - Structured Requirements Interview: Asks targeted questions about checkout revision, built-in versus separate client mode, customer journeys, and deployment constraints. - Capability Matrix & Contract Validation: Traces data loaders, GraphQL operations, access rules, and provider adapters to classify each feature as verified, presentation-only, backend-blocked, or absent. - Use Case: A team wants to rebrand the kit catalog and checkout experience. The Skill inspects the actual routes and named operations, identifies which changes are presentation-only versus requiring new backend mutations, and produces a safe implementation plan. ## Quick Start Ask the assistant to plan a custom storefront for the Openfront UIKit product by first inspecting the current source checkout and GraphQL schema.
