What problem does it solve? Customizing a Coffee Shop storefront without understanding the actual backend contract leads to broken flows, unauthorized GraphQL calls, and features that look complete but fail in production. This Skill grounds every change in the real source code, schema, and access rules before any implementation begins. ## Core Features & Use Cases - Source-Grounded Planning: Explains where behavior lives in features/storefront, app/** routes, Keystone models, and schema.graphql before proposing changes. - Structured Discovery: Interviews the user about goals, constraints, and environments, then produces a capability matrix classifying each feature as verified, presentation-only, backend-blocked, or absent. - Two Implementation Modes: Guides adapting the built-in storefront client or building a separately deployed client with pinned schemas, strict types, and server-side credential handling. - Use Case: A team wants to redesign the Coffee Shop pickup ordering flow with new branding. The Skill inspects the actual routes, GraphQL operations, and access rules, identifies which changes are presentation-only versus requiring backend work, and delivers a verified implementation plan. ## Quick Start Use this skill to plan a custom storefront for my Openfront Coffee Shop deployment and inspect the current source before proposing changes.
