What problem does it solve? Implemented interfaces often ship looking generic and interchangeable because no one checked whether the UI actually fits the product's users, workflows, and constraints. This Skill catches that problem before release by grounding critique in product evidence and enforcing a hard pass/fail finish gate. ## Core Features & Use Cases - Design Contract Creation: Captures the product's user, job, first-read object, density decision, interaction model, responsive priorities, and forbidden generic defaults before any critique begins. - Evidence-Based Review: Audits implemented screens across product legibility, hierarchy, pattern fit, states, responsive behavior, and implementation fidelity at desktop and mobile sizes. - Hard Finish Gate: Returns a clear PASS or HOLD decision with observable findings, required changes, and verification conditions instead of vague aesthetic feedback. - Use Case: Before releasing an analytics dashboard, run the review to discover that four equal-weight metric cards bury the retention decision, then get a concrete required change verified at 1440px and 390px including loading and empty states. ## Quick Start Review this implemented screen before release and return a finish-gate decision with evidence and required changes.
