What problem does it solve? UI reviews often produce vague, unsupported suggestions or accidental source changes. This Skill audits a product surface strictly against its own governing design system, proves every finding with contract, runtime, and correction evidence, and produces self-contained implementation plans without ever modifying product source code. ## Core Features & Use Cases - Evidence-gated UI audit: Traces the rendered path of one coherent surface, reconstructs its local design system, and keeps only findings backed by a binding design contract, a proven runtime path, and a single deterministic correction. - Read-only safety: Never edits product source, installs dependencies, or commits; all output lives under design-plans/ as Markdown plans another agent can execute. - Structured reporting and handoff: Reports at most three vetted findings in a confidence-ranked table, recommends the highest-leverage improvement, then writes self-contained plans using the included plan template. - Use Case: Ask it to review your app's settings page; it traces the components and tokens that actually govern that surface, reports only contradictions it can prove against documented design decisions, and drafts an implementation-ready plan for the finding you select. ## Quick Start Use the improve-ui skill to audit the primary product surface, identify supported UI problems, and recommend what to improve first without modifying anything.
