design-critique

Audit a UI across six evaluation lanes, each backed by an itemized reference checklist, and produce a prioritized improvement plan with severity-rated findings (P1–P4) and before/after fixes. The six lanes: - A. Accessibility — WCAG 2.2 contrast, use-of-color, focus, target size, reflow - B. Usability — Nielsen's heuristics, error messages, slips vs. mistakes - C. Cognitive load — Hick's Law, Von Restorff, Prägnanz - D. Affordances & conventions — Norman, Jakob's Law, Apple HIG (Clarity/Deference/Depth) - E. Visual hierarchy — Refactoring UI, Gestalt - F. Color & design systems — Material Design 3 roles, design tokens, product precedent Lanes can fan out to parallel sub-agents (a fusion-style panel); findings are deduplicated and severity-promoted when multiple lanes agree. Checklists carry adversarially-verified WCAG/Nielsen thresholds and an evidence-grading rule, so blocker-severity findings rest on verified facts. Preserves the existing theme. Asks the user to decide when a principle conflicts with intentional brand choices. Produces docs/design-critique/ with a findings list, impact/effort roadmap, and explicit trade-off decisions.
