What problem does it solve? Turning a product discovery brief into a coherent, reviewable design set normally requires manual coordination of token systems, screen flows, and prototypes. This Skill conducts the design phase of the A-Team harness, producing durable design tokens, a design.md with screens and flows, and a navigable lofi prototype in one pass. ## Core Features & Use Cases - Design token generation: Creates or consumes durable tokens (scale.ts, palette.ts, shadcn-theme.css) under docs/product/design-system/ with WCAG checks and a create-once guarantee. - Screens & flows drafting: Derives screen graphs from wireflow briefs or JTBD documents, emitting an executable flow-contract JSON handoff. - Lofi prototype conduction: Builds a greyscale navigable prototype with runtime-swappable variants under docs/features/<slug>/lofi/, calibrated by fidelity settings. - Use Case: After discovery has captured jobs-to-be-done in docs/product/jtbd/, run the design phase to produce tokens, a design.md with derived calls and flags, and a lofi prototype ready for human gate review. ## Quick Start Run the design phase for the current feature using the existing docs/product context and report any blocking flags for the gate review.
