What problem does it solve? Implementation plans often describe backend logic in detail while leaving UI/UX decisions vague or missing entirely, leading to generic, inconsistent interfaces discovered only after code ships. This Skill reviews a plan before implementation, rates each design dimension 0-10, and edits the plan to close the gaps. ## Core Features & Use Cases - Dimension-by-dimension rating: Scores information architecture, interaction states, user journey, specificity, and other design dimensions 0-10, explaining what a 10 would look like and fixing the plan to get there. - Outside design voices: Optionally runs parallel critiques via Codex (hard-rejection rules and litmus checks) and an independent Claude subagent, then synthesizes a consensus scorecard. - Plan editing, not just commentary: Directly updates the plan file with missing empty states, error states, responsive behavior, and accessibility requirements. - Use Case: Before implementing a new dashboard page, run this review to catch that the plan never specified loading states, mobile navigation hierarchy, or empty-state copy — and have those decisions written into the plan. ## Quick Start Ask the AI to run /plan-design-review on the current plan to rate its design completeness and fill in missing UI/UX decisions before implementation.
