These skills help an agent design, critique and improve user interfaces. They cover generating layout alternatives, reviewing a screen against design rules, and fixing accessibility problems found in an audit.
73 skillsPrevent and remove generic AI-generated design defaults, incoherent visual choices, and established UI defects while creating, revising, or reviewing websites, apps, screenshots, mockups, and design code. Use as a passive quality gate during UI work or for an explicit anti-slop cleanup; preserve the chosen art direction instead of forcing a neutral redesign.
Review a screen or flow across accessibility, layout, copy, typography, color and UI polish.
Survey a codebase's animation and motion code as a senior motion advisor, then produce a prioritized audit and self-contained implementation plans for other agents (or cheaper models) to execute. Read-only on source code — it plans improvements, it does not apply them. Use when the user asks to "improve the animations", "audit the motion", "make this app feel better", or wants a roadmap of animation fixes rather than a review of a single diff.
Structured UI design review — existing code (React/JSX, CSS, Tailwind) and, when behaviour matters, the running app in a real browser — reported as a prioritised Before / After / Why table. Covers visual hierarchy, spacing, typography, colour & contrast, component states, motion, responsiveness, accessibility, multi-page flow & navigation, and interaction continuity — grounded in Refactoring UI and Emil Kowalski's principles. For animation/jank/FPS, focus order, and cross-page UX it can drive Chrome via chrome-devtools-mcp to capture what a screenshot can't. Trigger when the user asks to "review this UI", "design review", "critique this component/screen/page or multi-page flow", asks why something "looks off", "looks AI-generated", or "looks like a wireframe", or wants to raise visual polish. For building UI from scratch use web-taste; for the full animation set see emilkowal-animations.
Audit websites, apps, screenshots, mockups, and design code for harmful AI-design clichés, generic generated defaults, and established UI defects. Use when the user wants evidence-backed design feedback, an anti-slop review, or a removal-first cleanup plan without a speculative redesign.
Deterministic design critique for HTML/CSS screens. Runs 73 slop guards extracted from the set of rules professional designers use in production-grade designs to catch the tells that make UI read as AI-generated (gradient-clipped headlines, the default indigo accent, puffy shadows, emoji icons, fake dot charts and decorated gauges, badges floated over the hero, eyebrow kickers above the H1, fake magazine mastheads, colored edge-stripe rails, two-tone headlines, over-designed list rows, layout-collapse bugs, em-dash copy, placeholder imagery), auto-fixes what can be safely rewritten, and reports the rest with concrete edits. Use whenever generated or hand-written HTML/CSS is about to be shown, exported, shipped, or committed, or when asked to critique a design, check it for slop, or give a second opinion on a generated screen.
Search a codebase or UI for places that don't animate but should, and reject everything that shouldn't. Read-only; it proposes motion with exact values, it does not implement it. Use when the user asks "what could be animated here?" or wants to "make this feel more alive". For fixing existing animations, use improve-animations or review-animations instead.
Audits font loading, type scales, measure, spacing, OpenType, and rendered punctuation with 78 scoped rules. Use when asked to "audit typography", "fix the fonts", or "review my type system". For a new visual direction use ui-design Direction; for general UI defects use ui-design Audit.
Audit an existing product surface against its own design evidence, identify verified UI problems, and write self-contained implementation plans for another agent. Strictly read-only on product source. Use when asked to review, refine, improve, or clean up an interface without replacing its identity; investigate design-system drift; or prepare a design handoff.
Review a branch, pull request or uncommitted change for introduced UI regressions.
Compare AI design skills for design systems, shadcn/ui, frontend creation and interface refinement, with practical briefs to help you choose a workflow.
Use a critique or rules skill when you already have screens, a variants skill when you want options to compare, and an AccessLint skill when the goal is fixing accessibility issues.
