What problem does it solve? It prevents teams from building permanent React/Inertia UI before the design direction is validated, by enforcing a dual-track workflow where backend domain work and hi-fi kit prototyping proceed together and the founder approves a prototype before live implementation. ## Core Features & Use Cases - Dual-track workflow: Coordinates backend Pest/domain work with UX psychology notes, placement decisions, and light hi-fi kit prototypes. - Gated permanent UI: Requires capability truth, UX placement notes, a kit prototype, and founder selection before writing permanent React/Inertia components. - Foundation pass exception: Skips alternate prototypes when an accepted kit already exists, aligning live foundation surfaces and stripping dead chrome. - Use Case: When adding a new marketplace listing page to a Laravel + Inertia + React app, produce one or two hi-fi kit prototypes themed to the design kit, get founder approval, then implement the permanent page with Pest and UI verification. ## Quick Start Ask the AI to apply the ui-kit-first-development workflow to prototype and then implement a new product page using the design kit before writing permanent React components.
