What problem does it solve? Plans with UI scope often ship with missing design decisions: no empty states, no hierarchy, no edge-case handling, and generic AI-looking layouts. This Skill reviews a plan with a designer's eye before implementation, rates each design dimension 0-10, and fixes the plan so the design is intentional rather than accidental. ## Core Features & Use Cases - Dimension-by-dimension plan review: Rates each design dimension 0-10, explains what would make it a 10, then edits the plan to close the gaps. - AI mockup generation: Uses the gstack designer binary to generate visual mockups, style variants, comparison boards, and vision-based quality checks from design briefs. - UI scope detection: Exits early when a plan has no UI surface, avoiding forced design review on backend-only changes. - Use Case: You have a plan for a new dashboard page. Run this Skill in plan mode to get mockups of the layout, a critique of empty states and responsive behavior, and an updated plan with concrete typography, spacing, and accessibility decisions. ## Quick Start Ask the assistant to run /plan-design-review on the current plan to critique its UI and UX decisions and add missing design details before implementation.
