Design & UI
Critique UI/UX designs for clarity, hierarchy, interaction, accessibility, and craft. Use for design reviews, PR feedback on UI changes, evaluating mockups, checking if a component is ship-ready, or when honest feedback is needed on whether something meets a high bar.
Browse and install components from the Elements registry (tryelements.dev). Use when user asks about available components, wants to explore providers, says "elements", "component library", "what components", "install from registry", "tryelements", or needs to find the right component category.
Analyze an existing website before improve, redesign, rebuild, or migration decisions. Use when a project has a current URL, local HTML/codebase, screenshots, sitemap, robots, analytics export, asset folder, or legacy site materials and needs a local-first audit with approval-gated crawling or authenticated access.

Renders configurable gameplay blocks (gift box, blind box, leaderboard rules, leaderboard gifts, single-leaderboard Top3, etc.) based on the uiMeta delivered by page-center. Coding conventions match ui2 components and follow ui2-upgrade-guide. Applicable scenarios: creating new building-block components, copying and revising existing blocks, and filling in types/config/composables according to the established conventions.
Runs a PM-perspective design critique focused on product outcomes and user goals, not aesthetics. Use when asked for a PM design critique, a product review of a Figma design, or feedback from a product perspective without needing to be a designer. Produces structured outcome-based feedback tied to user goals, business metrics, and requirement coverage.
Build Flutter forms with Form, TextFormField, DropdownMenuFormField, and custom FormField. Covers validation, AutovalidateMode, forceErrorText, theme-driven InputDecoration, autofillHints, keyboards, and focus traversal on Flutter 3.47+. Use when adding or fixing a login, signup, checkout, or any validate/save form; when fields jump, lose text, skip autofill, or ignore FormState.validate(); or when the user runs /flutter-building-forms
Design and implement purposeful, performant, and accessible motion in Flutter. Use for transitions, micro-interactions, gesture feedback, animated state changes, shared elements, list choreography, reduced-motion behavior, or diagnosing animation quality and performance.
Verify rendered Flutter interfaces through screenshots, golden tests, breakpoint comparisons, state matrices, and structured visual critique. Use when asked to compare designs, inspect polish, validate responsive or theme behavior, diagnose visual regressions, or confirm implementation quality after UI changes.
Frontend engineering standards — component architecture, state, async, forms, accessibility, performance and TypeScript discipline. Detects the project's framework and loads only the matching guidance. TRIGGER — load BEFORE writing or editing frontend code, not after: any .tsx, .jsx, .vue, .svelte, or component/hook file is being created or edited; the prompt names a component, hook, prop, state, form, modal, route, page, React, Next, Solid, SolidStart, solid-js, signal, useState, useEffect, createSignal, createStore, createResource, createAsync, <For>, <Show>, store, context, a11y, or web vitals. Trigger on plain feature requests in a frontend repo — "add a button", "wire up this form", "make this load faster", "fix this rerender" — the user will not say "best practices"; the component file is the trigger. Load it even when another skill (tdd, impeccable, simplify) is already active. SKIP only for backend-only work with no UI file touched.

Triggers include requests like 'design a todo app', 'create responsive layout', 'which UI library should I use', 'implement dark mode', 'build a form with validation', or 'make this mobile-friendly'.
A unified entry point for high-quality frontend design and implementation. Use to create, refactor or refine homepages, personal brand pages, portfolios, landing pages, dashboards, forms, cards, navigation and other web UI; first analyze the project stack and existing design system, then define a differentiation direction, implement production-grade code, and invoke interaction or motion specialist skills as needed.
Game feel consulting based on Steve Swink's "Game Feel: A Game Designer's Guide to Virtual Sensation" (Morgan Kaufmann, 2009). Use when helping with control responsiveness, input mapping, physics tuning, avatar movement, jump mechanics, polish effects, or analyzing why controls feel "floaty", "tight", "responsive", or "sluggish". Covers the psychology of real-time control, metrics for measuring feel, and practical tuning guidance.
